Problems solved by technology

Traditional white latex mostly uses vinyl acetate, polyvinyl alcohol, and even starch as the main raw materials. Not only is the polymerization process complicated and the production cycle is long, but the white latex itself has shortcomings such as poor water resistance and easy degumming of the bonded parts when exposed to water. Gelation is common under low temperature conditions in winter, and the drying speed is slow, the initial adhesion is weak, and the string is drawn, so it is inconvenient to use

Abstract

The invention relates to a strong white emulsion which is prepared from the following raw materials in percentage by weight: 44-46 parts of vinyl acetate, 5-8 parts of polyvinyl alcohol, 1-5 parts of dibutyl phthalate, 0.1 part of ammonium persulfate, 13-16 parts of alcohol, 0.1 part of water repellents and 21-24 parts of water. The product disclosed by the invention has the advantages of good low-temperature resistant property and water-resistant property, high product bonding strength, convenience for use and production cost reduction.

Description

Technical field: [0001] The invention belongs to an adhesive, and particularly relates to a strong white latex. Background technique: [0002] White latex is currently one of the most widely used and most used adhesives. It is widely used in wood processing, architectural decoration, printed matter binding, leather, textile and other industries. Traditional white latex mostly uses vinyl acetate, polyvinyl alcohol, and even starch as the main raw materials. Not only is the polymerization process complicated and the production cycle is long, but the prepared white latex itself has problems such as poor water resistance and easy degumming when the adhesive is exposed to water. Gelation is common under low temperature conditions in winter, and the drying speed is slow, the initial adhesion is weak, and the drawing is inconvenient. Summary of the invention: [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings in the prior art, and provide a str...
