Abstract

The invention discloses an adhesive for metal glue joint. The adhesive comprises, by weight, 20-30 parts of butadiene rubber based magneto-rheological elastomers, 10-20 parts of fully-vulcanized superfine powder butadiene styrene rubber, 10-20 parts of 4, 4'-diphenyl-methane-diisocyanate, 6-12 parts of polytetrahydrofuran polyether, 12-18 parts of organic attapulgite / polyurethane elastomer nanocomposite, 8-15 parts of plant glue, 2-5 parts of coupling agents and 1-3 parts of initiating agents. By means of the adhesive for the metal glue joint, the adhesion is highly firm, the adhesion time is short, and the volatilization of harmful substances can not occur.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an adhesive used for metal bonding. Background technique [0002] Adhesive bonding (bonding, bonding, cementation, gluing) refers to the technology of connecting the surfaces of homogeneous or heterogeneous objects with adhesives, which has the characteristics of continuous stress distribution, light weight, or sealing, and low temperature in most processes. Gluing is especially suitable for the connection of different materials, different thicknesses, ultra-thin specifications and complex components. Glue is the fastest growing in modern times, with a wide range of applications, and has a major impact on the progress of high-tech science and technology and the improvement of people's daily life. Therefore, it is very important to research, develop and produce various adhesives. [0003] However, the adhesives currently used for metal-to-metal bonding have insufficient bonding fastnes...
