AI Technical Summary

Technical Problem

The poor bonding strength and insufficient heat resistance of SBS spray glue lead to prone to aging and opening of glue in high temperature environments. The existing improved methods are costly, complex in production and affect product quality.

Method used

Using SBS thermoplastic styrene butadiene rubber, tackifying resin, environmentally friendly solvent and additives, high-bonding strength heat-resistant SBS spray glue is prepared by adding trimers, catalysts and rubber vulcanizing agents, and the glue is promoted by using the different volatility properties of the solvent. The crosslinking degree of SBS thermoplastic styrene butadiene rubber is controlled.

Benefits of technology

It has achieved the improvement of high bonding strength and heat resistance, simple production process, energy saving and consumption reduction, small product odor, comply with environmental protection standards, and is suitable for high-end soft furniture and luggage industries.

Abstract

The invention discloses a high-bonding-strength heat-resistant SBS spray adhesive and a preparation method thereof, and belongs to the field of adhesives. The high-bonding-strength heat-resistant SBS spray adhesive is prepared from the following components in parts by weight: 70 to 85 parts of SBS thermoplastic styrene-butadiene rubber, 50 to 60 parts of tackifying resin, 100 to 120 parts of solvent, 5 to 8 parts of tripolymer, 3 to 5 parts of catalyst and 3 to 6 parts of rubber vulcanizing agent, wherein the solvent comprises a first solvent and a second solvent, the volatilization rate of the first solvent is smaller than that of the second solvent, and the volume ratio of the first solvent to the second solvent is (8-10): 1. After the glue is sprayed on the surface of a material, stable basic adhesive force can be provided, in a high-temperature environment, double bonds of SBS thermoplastic styrene butadiene rubber are subjected to a cross-linking reaction under the action of a catalyst, and a polymer with a cross-linked network structure and high cohesion is generated. Therefore, the adhesive is higher in bonding strength and better in heat resistance.
