Abstract

The invention relates to an acrylate emulsion pressure-sensitive adhesive and a preparation method thereof. The acrylate emulsion pressure-sensitive adhesive comprises, parts by weight, 10-35 parts of seeded emulsion, 40-85 parts of pre-emulsion A, 4-27 parts of pre-emulsion B, 0.2-0.8 part of sodium hydrogensulfite and 0-5 parts of curing agent. The acrylate emulsion pressure-sensitive adhesive and the preparation method thereof are characterized in that a common emulsifying agent, the specific adhesive-preparing process and a specific monomer raw material are adopted, the raw material is low in cost and can be easily obtained in the market, and the prepared acrylate emulsion pressure-sensitive adhesive is stable in quality, good in coating performance and wide in application range and can be used for ordinary and high-grade polyethylene protective films, polrvinyl chloride protective films, polypropylene protective films and the like. After prepared protective films are torn off, no pressure-sensitive adhesive is left on the base material surface, and no shadow exists.

Description

technical field [0001] The invention relates to an acrylate emulsion pressure-sensitive adhesive and a preparation method thereof, more specifically, the invention relates to an acrylate emulsion pressure-sensitive adhesive for a protective film and a preparation method thereof. Background technique [0002] The application range of the protective film is getting wider and wider, and can be applied on the surface of metal products, coated metal products, plastic products, automobile products, electronic products, signage products, profile products, and other product surfaces. Most of the pressure-sensitive adhesives for protective films use solvent-based adhesives. With the improvement of environmental protection requirements, people begin to use emulsion-type pressure-sensitive adhesives on protective films. However, emulsion-type pressure-sensitive adhesives generally have poor water resistance and poor heat and humidity resistance. It is easy to produce shadow phenomenon ...
