Abstract

The invention provides an organic silicon modified acrylic pressure-sensitive adhesive and a preparation method thereof. The adhesive is prepared from the following raw materials in parts by weight: 7-9 parts of acrylic acid, 150-170 parts of butyl acrylate, 150-170 parts of isobutyl acrylate, 18-20 parts of styrene, 3-5 parts of hydroxyethyl acrylate, 0.7-1.0 part of benzoyl peroxide, 3-5 parts of dilauroyl peroxide, 12-25 parts of hydroxyethyl methylacrylate, 3-5 parts of vinyl silicone oil, 0.5-1.5 parts of hydrogen-containing silicone oil, 0.01-0.03 part of platinum catalyst, 14-17 parts of ammonia water, and 200-250 parts of deionized water. The preparation method disclosed by the invention is good in emulsifying effect, free of implosion and gel phenomena, and capable of ensuring that the prepared acrylic pressure-sensitive adhesive is good in comprehensive performance. The acrylic pressure-sensitive adhesive has high temperature resistance and aging resistance, meanwhile, the phenomena of implosion and gel are avoided in the preparation process, and it can be guaranteed that the prepared acrylic pressure-sensitive adhesive is good in comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesives, in particular to an organosilicon-modified acrylic pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] At present, the materials used for surface protection film include acrylic, epoxy resin, polyurethane, silicone materials and hybrid materials, etc. Among them, acrylic and silicone have their own advantages, and acrylic pressure-sensitive adhesive has moderate performance and low price; silicone pressure-sensitive adhesive Sensitive glue has good temperature resistance and aging resistance, but it is more expensive. [0003] At present, it is known that the important factors affecting the performance of acrylic pressure-sensitive adhesives include the influence of glass transition temperature, the influence of polymer molecular weight and its molecular weight distribution, the influence of polar groups, the influence of cross-linking,...
