VAE Emulsion For Paper Industry

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.  

VAE(ethylene-vinyl acetate copolymer) emulsions are widely used in civil engineering and building structures because of their excellent water resistance, acid and alkali resistance, aging stability and low price.   VAE emulsion is non-toxic, odorless, green and environmentally friendly, and has excellent bonding effect on many different surfaces. It is an excellent adhesive. In the field of construction, it can be used to prepare tile adhesive, concrete repair, building insulation wall construction, self-leveling mortar and other fields.   The waterproof coating with VAE emulsion as the base material has excellent weather resistance, acid and alkali resistance and UV resistance. It can be used for waterproofing treatment of special-shaped roofing, repair of old roofing and construction of colored roofing, and for waterproofing coating of sanitary ware.   The addition of VAE emulsion to cement can not only greatly improve the strength of cement, but also achieve excellent results in repairing concrete and anti-seepage treatment of reservoir.   VAE emulsion mixed in mortar can increase the strength, can improve the adhesion to various substrates, can increase the resistance and impact resistance, can improve the water absorption and water permeability, can improve the chemical resistance, this polymer mortar due to its excellent performance, is now widely used.   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.  

The formulation and production process of vae emulsion waterproofing materials involve a variety of ingredients and steps.   Formulation: The main component of VAE emulsion is vinyl acetate copolymer, which provides adhesiveness, stability and elasticity, as well as emulsifier, defoamer, stabilizer and auxiliary agent. These ingredients help to form a stable emulsion state, increase its adhesion and durability, and depending on the specific application needs, additives such as thickeners and preservatives may be added.   Production process: The production process includes raw material preparation, mixing, heating, emulsification, pH adjustment and adding additives. First of all, the ethylene acetate copolymer and other raw materials are added to the reaction kettle, adding an appropriate amount of water to stir and mix, and then heating to a certain temperature to start the polymerization reaction, adding emulsifier through stirring and high-speed shear to form a stable emulsion, adjust the pH value according to the need, and finally add additives, packaging and sealing.    In addition, there are other ingredients such as polyurethane emulsion, thickener, dispersant, etc., used to improve the bond strength, durability, softness, wrinkle resistance and so on. These ingredients are widely used in different fields such as building materials, textile printing and dyeing, paper industry, coatings industry and adhesives.   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.   Related Products: VAE CW 40-705 VAE CW 40-707 VAE CW FH-Ⅱ
