Abstract

The invention relates to a high-temperature-resistant hot-melt pressure-sensitive adhesive, which comprises the following components in parts by mass: 30-150 parts of a thermoplastic elastomer, 10-40parts of industrial gelatin, 50-120 parts of a tackifying resin, 5-15 parts of a plasticizer, 30-80 parts of an acrylic monomer, 3-7 parts of a cross-linking accelerator and 1-3 parts of an antioxidant. According to the invention, improvement is made on the basis of an existing solvent processing technology, and colloid is prepared in a melting, stirring and extruding mode, so that environmental pollution caused by volatile gas and the like due to use of a solvent is greatly reduced, and the mechanical property of the colloid prepared in a melting, stirring and extruding mode is not greatly different from that of an existing solvent processing technology.

Description

technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to a high-temperature-resistant hot-melt pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Removable adhesive tape is easy to remove after bonding, and does not leave any glue after removal. It has been widely used to fix components in electronic products, such as batteries, screens, etc. Due to the development of thinner electronic products and the application of 5G technology, higher requirements are placed on the performance of removable tapes, the most important of which is temperature resistance. Solvent processing methods are used in the existing processing technology, but solvent processing will produce many by-products, and now environmental protection regulations are becoming more and more stringent, and pollution control is becoming more and more strict. [0003] In view of the above technical problems, Chinese Patent Appli...
