Abstract

The invention discloses a special modified polyvinyl acetate emulsion adhesive and a preparation method of the special modified polyvinyl acetate emulsion adhesive. The raw materials comprise, by weight, 40%-50% of water, 40%-50% of vinyl acetate, 2%-5% of polyvinyl alcohol, 3%-9% of butyl ether acetate, diethylene glycol formate and propylene carbonate, 0.1%-0.2% of persulfate, 0.05%-0.1% of a defoaming agent and 0.1%-0.2% of a preservative. According to the special modified polyvinyl acetate adhesive disclosed by the invention, three special plasticizers, namely butyl ether acetate, diethylene glycol formate and propylene carbonate, are added, so that the adhesive has special performance, an adhesive film is soft and tough after being dried, and adhesion between glass and wood can be completed. And the adhesive shear strength is equivalent to that of the similar polyvinyl acetate emulsion adhesive on the market, and is determined according to the chemical industry standard (HG / T2727-2010) of the polyvinyl acetate emulsion woodworking adhesive.
