| titleOfInvention | Polyvinyl acetate emulsion |
| abstract | The invention discloses PVAc (polyvinyl acetate) emulsion which is prepared from the following substances in percentage by mass: 25-50 percent of VAc monomers, 30-50 percent of a dispersing medium, less than or equal to 10 percent of protection colloid, 1-5 percent of an emulsifier, 0.1-0.2 percent of an initiator, 0.1-0.2 percent of a pH adjusting agent and 5-40 percent of a plasticizer, wherein the protection colloid is polyvinyl alcohol; the emulsifier is a mixture of alkylphenol ethoxylates serving as a non-ionized emulsifier and alkylphenol ether ammonium sulfate salt serving as an anionic emulsifier; the dispersing medium is water; the plasticizer is a polyester plasticizer, obtained by performing esterization reaction on phthalic anhydride, adipic acid, pentanediol and diethylene glycol, with the molecular weight of 700-1,000. The PVAc disclosed by the invention is low in preparation cost and high in bonding strength and can be used for adhering glass fiber chopped strand mats. |
