Fiber surface PE protective film pressure sensitive adhesive and preparation method thereof

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...

[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 peeled off, there will be residual glue on the protected surface, so a PE film with good use effect will be developed. Protective film pressure-sensitive adhesive has been put on people's research agenda
