Title:
MEDIUM VISCOSITY PROTECTIVE FILM EMULSION AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/197056
Kind Code:
A1
Abstract:
A medium viscosity protective film emulsion and a preparation method therefor. The medium viscosity protective film emulsion comprises the following components: an acrylate monomer, a functional monomer, an emulsifier, an initiator, a neutralizing agent, and deionized water. Preferably, methyl methacrylate is a hard monomer, butyl acrylate and iso-octyl acrylate are soft monomers. Although the amount of the functional monomer is small, after a small amount of such monomer is added and is subjected to a polymerization reaction with the soft and hard monomers, the prepared acrylate emulsion polymer contains an amount of functional group with a high polarity, and thus can obviously increase the cohesive force and adhesive property of an adhesive. The pre-emulsified seed polymerization process is used, excellent water resistance is achieved, and at the same time excellent compliance is achieved, and the film suffers little change over time. Furthermore, the peeling force of a protective film prepared by the product does not increase by more than 10% after sticking to a board for half a year, and the protective film is easily peeled off when the protective film is removed, and does not pollute the surface of a substrate.
