Problems solved by technology

[0005] The embodiment of the present invention aims to solve the technical problem that the performance of the emulsion-type acrylic pressure-sensitive adhesive is difficult to have both acid resistance and temperature resistance at the same time. It aims at the technical deficiency of the existing emulsion-type acrylic pressure-sensitive adhesive, and provides an acid-resistant >80°C / 4h, acid-resistant and temperature-resistant emulsion-type acrylic pressure-sensitive adhesive with temperature resistance >120°C / 1h performance, and its preparation process

Abstract

An acid-resistant and temperature-resistant emulsion-type acrylic pressure-sensitive adhesive, which relates to resin encapsulation, sealing and fixing in the fields of optical lenses, optical materials, electronic information industry and other materials, including monomers, emulsifiers, initiators, residual monomer treatment agents, pH neutralizer, curing agent and deionized water. The technical solution applies the principle of pressure-sensitive adhesive structure mechanics as the core, focusing on the interaction of lauryl acrylate (LA) and 2-ethylhexyl acrylate (2-EHA) sequence combination to adjust acid resistance>80℃ / 4h, both temperature resistance >120℃ / 1h performance index construction. The acid-resistant and temperature-resistant emulsion-type acrylic pressure-sensitive adhesive disclosed in the embodiment of the present invention is an "oil-to-water" benzene-free, halogen-free, and aldehyde-free water-based product, which not only solves the problem that normalized products are subject to solvent-based pressure-sensitive adhesives The restricted use of glue and the harm of organic solvents also break through the technical barriers of acid resistance and temperature resistance accumulated by emulsion-type acrylic pressure-sensitive adhesives, which are beneficial to the coating and processing of optical lenses, optical materials, and electronic information industries.

Description

technical field [0001] The embodiments of the present invention belong to resin encapsulation, sealing and fixing in the fields of optical lenses, optical materials, electronic information industry materials, etc., and in particular relate to an acid-resistant and temperature-resistant emulsion type acrylic pressure-sensitive adhesive and its preparation process. Background technique [0002] At present, the existing solvent-based rubber series pressure-sensitive adhesives, solvent-based silicone pressure-sensitive adhesives, solvent-based acrylic pressure-sensitive adhesives, and imported emulsion-type acrylic pressure-sensitive adhesives, because of their acid-resistant and temperature-resistant adhesion, sealing and fixing Function, has been widely used in optical lenses, optical materials, electronic information industry and other fields. Among them, the production and supply channels of a small number of solvent-based rubber series pressure-sensitive adhesives in China ...
