Problems solved by technology

[0002]Emulsion polymerization uses water as the medium, which can increase the molecular weight of the polymer. It is low in cost and has no environmental pollution. It has been widely used in adhesives, coatings, inks and Rubber industry field, but because of its poor peel strength and high temperature resistance, its application in special fields is limited. In order to expand its application field, the present invention modifies acrylate

Abstract

A high-performance water-based acrylate pressure-sensitive adhesive comprises the following components in parts by weight: 75-120 parts of monomers, 0.3-0.5 part of sodium bicarbonate, 1.5-3 parts of an emulsifier, and 0.2-0.5 part of an initiator, wherein the monomer comprises the following components in parts by weight: 40-60 parts of 2-ethylhexyl acrylate, 20-30 parts of vinyl acetate, and 15-30 parts of glycidyl methacrylate; the emulsifier comprises the following components in parts by weight: 0.5-1 part of sodium dodecyl sulfate and 1-2 parts of double phenethyl polyoxyethylene ether; the initiator is 0.2-0.5 part of potassium persulfate. The pressure-sensitive adhesive has relatively high initial adhesion, permanent adhesion and solvent resistance.

Description

technical field [0001] The invention relates to a high-performance water-based acrylate pressure-sensitive adhesive and a manufacturing process thereof, belonging to the field of organic chemical industry. technical background [0002] Emulsion polymerization uses water as the medium, which can increase the molecular weight of the polymer. It has low cost and no environmental pollution. It has been widely used in adhesives, coatings, inks and rubber industries. However, due to its poor peel strength and high temperature resistance , which limits its application in special fields, in order to expand its application field, the present invention modifies acrylate. Contents of the invention [0003] The purpose of the present invention is to provide a high-performance water-based acrylate pressure-sensitive adhesive and a preparation method thereof. [0004] In order to achieve the above object, a high-performance water-based acrylate pressure-sensitive adhesive of the pres...
