High temperature resistance hot-melt pressure-sensitive adhesive

Abstract

The invention relates to a high temperature resistance hot-melt pressure-sensitive adhesive, which is characterized by comprising 12-13% of natural rubber, 12-13% of petroleum rubber, 20-22% of petroleum resin, 20-22% of terpene resin, 10-11% of alkyl phenolic resin, 14-15% of naphthenic oil, 3.0-3.5% of rubber accelerator and 1-3% of anti-aging agent. By the above technical scheme, solubleness, thermoplasticity and rebound resilience of the SBS series pressure-sensitive adhesive can be ensured, and the high temperature softness and cohesiveness of the pressure-sensitive adhesive can be enhanced.

Description

technical field [0001] The invention belongs to the field of adhesives, and specifically refers to a high-temperature-resistant hot-melt pressure-sensitive glue used for producing adhesive tapes. Background technique [0002] Pressure-sensitive adhesives are mainly acrylic and rubber-based solvent-based or latex-based adhesives. In order to achieve high-speed operation, reasonable coating, and the need to eliminate solvent pollution and other problems, hot-melt pressure-sensitive adhesives have been developed. Hot-melt pressure-sensitive adhesives integrate the characteristics of hot-melt adhesives and pressure-sensitive adhesives. convenient. [0003] The main component of pressure-sensitive adhesive is thermoplastic elastomer pressure-sensitive adhesive, which is basically composed of SBS (thermoplastic styrene-butadiene rubber), SIS (block copolymer of styrene and isoprene), tackifying resin, softener, Anti-aging agent and coloring agent are to be formed. However, its ...
