Problems solved by technology

[0003] Due to the low viscosity of the existing pressure-sensitive adhesive, in order to ensure the bonding quality, it is necessary to coat a large amount of pressure-sensitive adhesive on the PE film, but because the thickness of the PE film is relatively thin, when a large amount of pressure-sensitive adhesive is coated, The press

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...

Abstract

The invention discloses a fiber surface PE protective film pressure sensitive adhesive, which is prepared from the following raw materials by mass portion: 30 to 38 portions of acrylic acid 2-ethylhexyl acrylate, 0 to 4 portions of vinyl acetate, 0.4 to 2 portions of hydroxy-ethyl acrylate, 1.6 to 4 portions of acrylic acid and 55 to 60 portions of solvent. The PE protective film pressure sensitive adhesive prepared by the process is good in viscosity, can achieve a pressure sensitive effect by coating in a small amount during use, avoids PE thin film protruding and winding during drying due to small coated amount and prevents residual adhesive on a protected surface when the protective film is stripped, thereby being widely used for the manufacturing of PE protective films.

Description

technical field [0001] The invention relates to a protective film pressure-sensitive adhesive, specifically a PE protective film pressure-sensitive adhesive used on the surface of fibers, and also relates to a preparation method of the protective film pressure-sensitive adhesive. Background technique [0002] At present, the protective film used on the fiber surface is made of PE film as the base material, rubber or acrylate polymer as the pressure-sensitive adhesive, and processed by coating and drying methods. [0003] Due to the low viscosity of the existing pressure-sensitive adhesive, in order to ensure the bonding quality, it is necessary to coat a large amount of pressure-sensitive adhesive on the PE film, but because the thickness of the PE film is relatively thin, when a large amount of pressure-sensitive adhesive is coated, The pressure-sensitive adhesive will shrink during the drying process, which will cause the PE film to roll, and when the protective film is pe...
