Abstract

The invention discloses a polyacrylate pressure-sensitive adhesive emulsion for a polyethylene protection film and a preparation method thereof. The environment-friendly pressure-sensitive adhesive emulsion employs a single component, can realize good cross-linking and curing only through heating and drying without addition of other cross-linking agents and uses a polymerization type emulsifier to reduce a variety of adverse problems caused by emulsifier migration. The environment-friendly pressure-sensitive adhesive disclosed in the invention has good adhesion on the polyethylene film and can realize good balance among initial viscous force, peeling strength and cohesive force.

Description

technical field [0001] The invention relates to a polyacrylate pressure-sensitive adhesive emulsion, more specifically, the invention relates to an environment-friendly polyacrylate pressure-sensitive adhesive for polyethylene protective film and a preparation method thereof. Background technique [0002] Protective film is a surface protection and packaging material used to protect the surface of commodities. It is pasted on various metals, aluminum-plastic panels, plastic panels, coated steel, stainless steel panels, aluminum profiles, stone, glass, instruments, and furniture. Such as the surface of the commodity, so that it can protect the surface during manufacturing, transportation, secondary processing, storage and use, prevent the commodity from being polluted, scratched and slow down the oxidation of the commodity surface. The application of protective film can not only improve the appearance quality of products and facilitate material processing, but also improve th...
