Abstract

The invention relates to the technical field of metal and rubber bonding adhesives, and provides a single-coating type metal and rubber heat vulcanization adhesive. The adhesive at least comprises thefollowing components in percentage by weight: 4-20% of liquid rubber, 5-20% of a Diels-Alder graft polymer, 1-5% of a hydroxyl aromatic compound, 1-5% of a formaldehyde source, 0.5-3% of a cross-linking agent, 0.5-3% of a vulcanizing agent, 0.5-5% of an acid acceptor, 1-10% of an inert pigment filler and the balance of a solvent. According to the adhesive, high-vinyl liquid polybutadiene rubber is compounded for use, so that the adhesive not only can endow a bonding layer with excellent peeling strength and crosslinking density, but also can be beneficial to enhancing the bonding durability of the bonding layer and still can keep very good stability under relatively harsh conditions.

Description

technical field [0001] The invention relates to the technical field of metal and rubber bonding adhesives, in particular to a single-coated metal and rubber thermal vulcanization adhesive and a preparation method thereof. Background technique [0002] In recent years, a variety of adhesive compositions have been developed for bonding various materials or objects, such as elastomeric substrates and metal surfaces. With the continuous development of bonding technology, adhesive compositions are faced with more and more demanding bonding conditions, and the range of ingredients used in compositions is constantly constrained by environmental regulations. In order to live well in this somewhat difficult atmospheric environment, future adhesive compositions will need to use environmentally acceptable ingredients, and the adhesive materials made of these ingredients must be able to withstand more stringent bonding. condition. Rubber and metal are bonded by adhesive, which is the ...
