Abstract

The invention relates to the field of adhesives, and particularly relates to a polyvinyl acetate adhesive which is characterized by comprising the following components in parts by weight: 100 parts of water, 6-8 parts of polyvinyl alcohol, 40 parts of vinyl acetate, 0.5-0.8 part of propyl alcohol, 1 part of copolymerization catalyst, 4-6 parts of hydrogen peroxide diisopropylbenzene, 1-2 parts of diisooctyl phthalate and 2-3 parts of anti-aging agent. Compared with the prior art, the polyvinyl acetate adhesive provided by the invention has the advantages of good water resistance, heat resistance, cold resistance and initial adhesion, high bonding strength and the like, and can be used as high-quality white latex to replace common white latex.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a polyvinyl acetate adhesive. Background technique [0002] Polyvinyl acetate emulsion is a commonly used white latex with low cost, convenient production and use, good performance, non-toxic, odorless, non-corrosive, and will not pollute the environment. It is mainly used for wood, decorative panels, paper processing, leather goods, wood and Bonding of cement products and printing and dyeing fixing agent, etc. However, the common polyvinyl acetate emulsion has poor cold resistance, and it is easy to gel in winter, reducing performance and use effect. Contents of the invention [0003] The object of the present invention is to provide a kind of polyvinyl acetate adhesive, to solve the defect that prior art exists. [0004] In order to achieve the above object, the following technical scheme is adopted: a polyvinyl acetate adhesive comprising the following components and parts by weig...
