Embodiment Construction
[0012] A PE protective film pressure-sensitive adhesive used on the surface of fibers, made of the following raw materials: 2-ethylhexyl acrylate: 30-38 parts, vinyl acetate: 0-4 parts, hydroxyacrylate Ethyl ester: 0.4-2 parts, acrylic acid: 1.6-4 parts, solvent: 55-60 parts;
[0013] The optimum parts by weight of the PE protective film pressure-sensitive adhesive is: 2-ethylhexyl acrylate: 35 parts, vinyl acetate: 2 parts, hydroxyethyl acrylate: 1 part, acrylic acid: 3 parts, solvent : 60 servings.
[0014] A method for producing the above-mentioned PE protective film pressure-sensitive adhesive, the steps are as follows:
[0015] 1): Weigh various raw materials in proportion;
[0016] 2): Add 2-ethylhexyl acrylate, vinyl acetate, hydroxyethyl acrylate, and acrylic acid into the solvent and heat to 80°C for stirring. Polymerization reaction occurs inside, and the material can be discharged in 8 hours.
[0017] The PE protective film pressure-sensitive adhesive produced by...
