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.
