Abstract

The invention relates to a heat vulcanization adhesive. The heat vulcanization adhesive comprises a solvent and solid components; on the calculation basis of 100 parts by weight of the solid components, the solid components comprise 30-45% by weight of phenol aldehyde / epoxy component, preferably 35-40% by weight; 1-2.5 parts by weight of first accelerator; 20-30% by weight of halogenated polyolefin, preferably 25-30% by weight; 1-2% by weight of co-vulcanization component; 10-15% by weight of metal oxide; 2-5% by weight of adhesion promoter; 1-2 parts by weight of wetting / dispersing agent; and the balance of inert filler. The invention further provides a preparation method of the heat vulcanization adhesive.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a phenolic / epoxy modified rubber-metal thermal vulcanization adhesive and a preparation method thereof. Background technique [0002] With the rapid development of the rubber industry, rubber composite materials are widely used in petrochemical, construction, transportation and other industrial fields by combining the high elasticity of rubber and the high strength of metal. Among them, the quality of rubber and metal adhesives is the key to the success of composite materials. The key is that with the increase in the types of composite products and the expansion of application fields, the requirements for bonding technology are becoming more and more stringent. The traditional chlorinated rubber method, isocyanate method and other technologies have been eliminated, and the mainstream products are chemlok, Thxion (Rohm and Haas), vulcanized rubber-metal adhesives from Sibang, England, whi...
