Vinyl acetate-ethylene copolymer emulsion is a polymer emulsion made of vinyl acetate and ethylene as basic raw materials, referred to as VAE emulsion or EVA emulsion in English. Since its introduction in 1965, it has been widely used in adhesives, building materials, coatings, papermaking, fabric processing, tobacco, packaging and other fields due to its excellent adhesion, permanent flexibility, good acid and alkali resistance and other properties.   In order to improve the performance of VAE emulsion and expand its application range, a lot of fruitful modification research has been done to improve the water resistance, mechanical strength, heat resistance, adhesion, curing speed and other aspects of VAE emulsion. These modification studies are mainly focused on the following directions: additive method, copolymerization method, composite modification method and blending method. Among them, the blending method is a method of physically blending VAE emulsion with one or more polymer solutions or emulsions to form a multi-component system. The properties of the various components of the blending method can complement each other, thereby obtaining new materials with better performance or new properties, reducing costs while potentially expanding the application field of VAE emulsion, allowing VAE emulsion to play a greater application value.   Polymer solutions or polymer emulsions that are often blended with VAE emulsions include: rosin resin, phenolic resin, urea-formaldehyde resin, terpene resin, polyurethane emulsion, acrylic emulsion, styrene-acrylic emulsion, vinyl acetate emulsion, styrene-butadiene emulsion, etc. Since VAE emulsion has good miscibility with a variety of emulsions, blending is the simplest and most direct way to achieve complementary properties of the blended components and obtain new properties.   PVAc emulsion was used to modify VAE emulsion, and at the same time, thickening resin and additives were used to synthesize an adhesive suitable for bonding non-polar plastic materials. The addition of thickening resin significantly improved the bonding strength of the emulsion; the addition of acidic metal salt crosslinking agent improved the water resistance of the system without affecting the stability of the emulsion.   VAE emulsion was modified by blending pure acrylic emulsion, acetic acid acrylic emulsion, silicone acrylic emulsion, styrene acrylic emulsion and VAE emulsion to prepare adhesive. The results show that the VAE emulsion modified by acrylate emulsion has been greatly improved in bonding performance and peel strength. Among them, the adhesive obtained by using acetic acid acrylic emulsion to modify VAE emulsion has the best comprehensive performance, especially the most obvious improvement in high temperature adhesion.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.  

Vinyl acetate-ethylene copolymer (VAE) emulsion is the abbreviation of vinyl acetate-ethylene copolymer emulsion. It is a polymer emulsion formed by copolymerizing vinyl acetate and ethylene monomers with other auxiliary materials through emulsion polymerization.   White latex is a water-soluble adhesive, a thermoplastic adhesive produced by polymerization of vinyl acetate monomer under the action of an initiator. Usually called white latex or PVAC emulsion for short, the chemical name is polyvinyl acetate adhesive, which is synthesized from acetic acid and ethylene to vinyl acetate, with the addition of titanium dioxide (low-grade ones add light calcium, talc, and other powders). It is then made by emulsion polymerization. A thick milky white liquid.   VAE emulsion has the advantages of permanent softness, water resistance, low temperature resistance, fast bonding speed, high bonding strength, and is safe and non-toxic. VAE emulsion is widely used in adhesives, exterior wall insulation, building waterproofing, coatings, composite packaging materials, building cement mortar modification, non-woven fabric manufacturing, paper coating and general adhesive for various polar and non-polar materials. Access and other fields.   The characteristics of white latex include normal temperature curing, fast curing, high bonding strength, good toughness and durability of the bonding layer and not easy to age. White latex is a widely used water-soluble adhesive. It is mainly used in wood bonding, construction industry, coatings, etc. It is also used in furniture assembly, surface repair, etc.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.

VAE (ethylene-vinyl acetate copolymer) emulsion viscosity is an important quality indicator and has a significant impact on product mass transfer, heat transfer, fluid flow, emulsion stability and emulsion transportation. Monomer ratio, polymerization temperature, initiator, emulsifier system optimization, electrolyte additives, and storage conditions are all factors that affect the viscosity of VAE emulsion.   1. Monomer ratio The selection and proportion of monomers directly affect the viscosity and other properties of VAE emulsion. The ratio of ethylene to vinyl acetate (VAc) is particularly critical. Generally speaking, VAE emulsions with a VAc content of 70% to 95% have higher viscosity. Increased VAc content will increase the flexibility and elasticity of the emulsion, and will also increase the viscosity of the emulsion.   2.Polymerization temperature control Polymerization temperature is another important factor affecting the viscosity of VAE emulsion. Changes in temperature will affect the rate of free radical generation and the rate of polymerization. Generally speaking, within a suitable temperature range, an increase in temperature will speed up the polymerization reaction, causing the latex particles in the emulsion to grow rapidly, resulting in an increase in viscosity. However, too high a temperature may cause the emulsion to gel, affecting its quality and stability.   3.Initiator The amount and type of initiator have a significant impact on the viscosity of VAE emulsions. Initiators mainly affect the rate of polymerization. When the amount of initiator is large, the polymerization reaction is fast, the number of generated latex particles increases, and the viscosity of the emulsion increases. However, excessive initiator may cause the reaction to be too fast and difficult to control, resulting in reduced emulsion performance. Different types of initiators generate different types of free radicals during the reaction and have different effects on the viscosity of the emulsion.   4. Emulsifier system optimization The selection and dosage of emulsifier are crucial to the stability and viscosity of VAE emulsion. The main function of emulsifier is to reduce the surface tension of emulsion and promote monomer dispersion and emulsion formation. Appropriate emulsifier concentration and anionic/nonionic emulsifier ratio can improve the stability of the emulsion and also affect the viscosity of the emulsion. The degree of polymerization and alcoholysis of protective colloids such as PVA (polyvinyl alcohol) also significantly affect the viscosity of the emulsion. The higher the degree of polymerization of PVA, the greater the viscosity of the emulsion; the higher the degree of alcoholysis, the lower the viscosity of the emulsion.   5.Electrolyte additives The addition of electrolyte additives can affect the viscosity and stability of VAE emulsions. Some electrolyte additives can compress the electric double layer of latex particles and reduce the electrostatic repulsion between latex particles, thereby increasing the viscosity of the emulsion. However, excessive amounts of electrolyte additives may cause aggregation in the emulsion, affecting its performance.   The factors that affect the viscosity of VAE emulsions include reaction time and rate, PH value, storage conditions and stability. In actual production and application, these factors need to be reasonably adjusted according to specific needs and conditions to obtain VAE emulsion products with excellent performance.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.

A variety of adhesives with different functions and uses can be prepared from VAE emulsion and its modified emulsions. Such as PVC film adhesive, interior decoration glue, plywood glue, floor glue, wallpaper glue, wood glue, paper-plastic composite glue, PVC plastic door special glue, difficult plastic bottle label glue, carpet back glue, cigarette glue, external wall insulation board glue, non-woven adhesive, aluminum foil glue, paper tube glue, binding glue, flock glue, leather glue, paulowood glue, roof waterproof glue. Here are some typical varieties.   1. PVC film adhesive: 50 parts VAE emulsion (CW40-707), 25 parts terpene resin aqueous dispersion (TSR-5112TP), 20 parts water and 5 parts ethyl acetate. After mixing evenly, the PVC film adhesive is obtained, and the water resistance of the bonded PVC film is better than that of the acrylic emulsion adhesive.   2. Special adhesive for PVC plastic and steel skin: Mixed with VAE emulsion 40-50 parts, rosin or rosin ester emulsion 20-25 parts, DOP 1 part, toluene 3 parts to 5 parts, defoam-0.3 parts to 0.5 parts, PVC plastic and steel skin special adhesive can be prepared for the bonding of PVC plastic and steel skin with plywood or wood-based board.   3. Building decoration glue: Add a small amount of DBP, inorganic fillers (such as paste precipitated barium sulfate, etc.) and auxiliaries to VAE emulsion to produce environmentally friendly white latex. An appropriate amount of VAE emulsion can also be added to polyvinyl acetate emulsion to obtain white latex such as HL-005 white latex with faster curing, less brittleness and better water resistance.   4. Adhesive for cigarette machine: the reference formula is 55 parts VAE emulsion (CW-707), 30 parts modified monomer, mixed soap-free emulsifier 1.0 parts, DBP5 parts, additives (castor oil), butyl phosphate, ethylene glycol, defoamer (n-octanol) small amount. It is used as an adhesive for lap, joint, molding and packaging of high speed cigarette machine.   5. Plywood adhesive: It is composed of VAE emulsion, DBP, ultra-fine calcined kaolin, fumed white carbon black, etc., adding 10-15 parts of MDI before use, and mixing evenly for bonding solid wood plywood.   6. Paulownia adhesive: The general adhesive used in the joint of paulownia jointing is easy to be red, yellow and black, especially in the rainy and humid hot season. The reason for the color development of paulownia joint may be that the paulownia itself contains a color substance, when the moisture content of the bonding place is higher, the color substance migrates to the joint, resulting in color development phenomenon, resulting in unqualified product quality. Using imported VAE emulsion, polyvinyl formaldehyde adhesive liquid, dibutyl phthalate, nano-calcium carbonate, precipitated barium sulfate and other adhesive, no red cracks were found.   7. Adhesive for building exterior wall insulation board: 100 parts VAE emulsion (CW-705LH), 40 parts quartz powder, 60 parts precipitated barium sulfate, 20 parts ultrafine calcinated kaolin, mixed into paste, adding cement and appropriate amount of water before use to adjust the viscosity required. Adhesive polystyrene foam (EPS) board and concrete, strong and durable.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.

When VAE is mixed with sand slurry, many properties are improved, but the properties of mortar are also different due to the amount of emulsion mixed in mortar. According to research, from the comprehensive point of view of performance and economy, it is considered that the P/C (polymer weight/cement weight) value is between 0.1 and 0.4.   Increase mortar strength: The fluidity (flow value) of the mortar increases with the increase of the amount of emulsion added, and can rely on mixing with the emulsion to reduce the amount of water, so as to obtain a dense hardened substance, and can increase the strength, so that the shrinkage rate and water absorption decline. Improve the brittleness of mortar: When VAE emulsions are mixed into it, vibration-absorbing polymer particles fill the cement Spaces, thus improving the impact resistance of the mortar. Improve chemical resistance: The mixed VAE emulsion can improve the acid resistance of the mortar and prevent the corrosion of salt water, machine oil, ammonia, methanol and other chemicals.   The use of synthetic resins can improve the strength and adhesion of concrete, mortar, etc: The synthetic resin solution is applied to the surface of the original concrete or mortar, and then the surface is covered with new concrete or mortar, which can eliminate the "rough work" process. At present, polyvinyl acetate emulsions and styrene-butadiene rubber latex are commonly used, and VAE emulsions have greater bond strength than these two emulsions. Pure mortar has no bonding strength for wood, metal, plastic, etc., and only when the polymer is mixed in, the mortar can bond with wood, etc. High strength can be obtained by curing in the air (it is not necessary to spray water onto the poured mortar). If the hydration reaction of cement products is not sufficient, then it cannot get the inherent strength, so if the mortar is cured in the air, then it is brittle and easy to crack. If VAE emulsions are mixed in, the strong hydration force of the emulsions prevents the mortar from losing water too quickly, thus providing the moisture needed for cement curing.   Website: www.elephchem.com Whatsapp: (+)86 13851435272 E-mail: admin@elephchem.com ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate–ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.
