Abstract

The invention relates to a preparation method of a water-based acrylate pressure-sensitive adhesive, and an application of the adhesive in household appliance protective films. A component A of the pressure-sensitive adhesive is an alkyl (methyl) acrylate polymer, and a component B of the pressure-sensitive adhesive is a polyfunctional aziridine-series crosslinking agent. The component A is obtained through polymerization of butyl acrylate, isooctyl acrylate, methyl methacrylate, butyl methacrylate, 2-hydroxypropyl acrylate, acrylic acid and (methyl) acrylate containing two double bonds, wherein the polymerization is initiated by ammonium sulfate. The pressure-sensitive adhesive provided by the invention has the advantages of good leveling property, less foam, fisheye-free property in coating, and the like. When the adhesive is applied on a needed substrate to prepare a household appliance protective film, the protective film has good high-temperature resistance, good high-humidity resistance and good aging resistance. When the protective film is torn from the surface of a household appliance, no residual adhesive or spot is left.

Description

technical field [0001] The invention relates to a pressure-sensitive adhesive, which is a pressure-sensitive adhesive having the advantages of good leveling performance, less foam, small latex liquid particle size and the like. The pressure-sensitive adhesive can be used in fields that have high requirements on the appearance of the pressure-sensitive adhesive tape, such as the surface protective film of household appliances and the like. Background technique [0002] Due to its universality, low cost and other advantages, transparent protective film is used more and more widely. The high-grade transparent protective film has higher requirements on the glue, which requires the glue to have good leveling properties, less foam, and no small gel pieces. Home appliance protective film is its typical representative. [0003] With the improvement of people's living standards, various household appliances have gradually entered thousands of households, which has brought about the...
