Abstract

The invention relates to a light-color hot-melt pressure-sensitive adhesive for a glass cloth adhesive tape and a preparation method thereof. The hot-melt pressure-sensitive adhesive is prepared fromthe following components in parts by weight: 20-45 parts of thermoplastic elastomer, 10-30 parts of modified organic silicon resin, 20-35 parts of tackifying resin, 5-10 parts of modified glass beads,1-3 parts of an antioxidant and 1-3 parts of a crosslinking agent, wherein the modified organic silicon resin is prepared by performing functional modification on organic silicon resin by adopting epoxy resin and organic fluorine resin. The preparation process is simple in steps and good in controllability, and the prepared hot-melt pressure-sensitive adhesive is light in color, good in temperature resistance, high in initial adhesion and good in permanent adhesion, is suitable for glass cloth adhesive tapes, and has a very good application prospect.

Description

Technical field [0001] The invention belongs to the technical field of polymer adhesives, and relates to a light-color hot melt pressure-sensitive adhesive for glass cloth tape and a preparation method thereof. Background technique [0002] As we all know, hot-melt pressure-sensitive adhesive is a kind of pressure-sensitive adhesive, which is mainly made by mixing synthetic rubber, resin and rubber oil, etc., heated to a molten state and then coated on a substrate such as tissue paper, cloth or plastic film. A new type of adhesive tape. Specifically, hot-melt pressure-sensitive adhesives have both hot-melt and pressure-sensitive characteristics. It becomes liquid when heated to 130-200°C, and can be used by spraying, roller coating, blade coating, etc., and it becomes solid when cooled to room temperature. A certain pressure can produce a good bonding effect. [0003] At present, with the continuous development of polymer chemistry technology, adhesive technology has also made gr...
