Abstract

The invention discloses a fluorosilicone modified aqueous pressure-sensitive adhesive used for a polyethylene protection film. The aqueous pressure-sensitive adhesive comprises 95-99w% of a fluorosilicone emulsion and 1-5wt% of a curing agent. The invention also provides a preparation method of the aqueous pressure-sensitive adhesive. The fluorosilicone modified aqueous pressure-sensitive adhesive disclosed in the invention has good adhesion to the polyethylene film, can realize the good balance of initial stick force, peeling strength and cohesive force, and has the advantages of storage stability, heat resistance, cold resistance, acid resistance, alkali resistance, salt resistance and the like.

Description

technical field [0001] The invention relates to a fluorine-silicon modified water-based pressure-sensitive adhesive, in particular to a fluorine-silicon-modified water-based pressure-sensitive adhesive for a 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 the util...
