Problems solved by technology

[0011] At present, it is difficult for commercially available thermal vulcanization adhesives to achieve good bonding to such high-hardness and high-strength ceramics. Under this trend, adhesives with better performance are needed to meet the bonding requirements for hard ceramics.

Abstract

The invention discloses a heat-vulcanization adhesive for adhering ceramics with elastomer. The heat-vulcanization adhesive comprises the following components in percentage by weight: 5-15% of phenolic resin, 5-15% of a film-forming agent, 0.5-5% of an extra formaldehyde source, 0.5-5% of an acid acceptor, 5-10% of an adhesion promoter and the balance solvent. The heat-vulcanization adhesive is characterized in that a phenolic compound supported by a silicane-containing modified organic porous material is used as the adhesion promoter, so that the adhesive forms a high-strength high-activity active transition layer between the elastomer and hard ceramics, and therefore, adhesion of the high-strength hard ceramics by the adhesive is effectively realized.

Description

technical field [0001] The invention relates to a thermally vulcanized adhesive containing silane-modified phenolic resin and superhard filler, which is used as a primer when bonding ceramics and elastomers. [0002] technical background [0003] A number of adhesive compositions that provide bonding to substrates such as elastomers and metals have been developed on the market. Usually the Mohs hardness of steel is around 4-5, while the Mohs hardness of ordinary silicate ceramics exceeds 8, and the hardness of pure alumina and zirconia ceramics is as high as 9. Compared with metal substrates such as steel, The requirements for bonding ceramic substrates are even higher. [0004] In the bonding mechanism, substrate bonding is nothing more than two major functions, one is physical effects, including penetration, anchoring, adsorption, etc.; the other is chemical effects, that is, the reaction with active groups on the surface of the substrate. In this way, for the bonding of ...
