Abstract

The invention discloses a metal adhesive and a preparation method thereof. The metal adhesive comprises, in parts by weight, 10-30 parts of E-51 epoxy resin, 5-12 parts of polyurethane formate, 10-30 parts of methyl propylene glycol diester, 2-8 parts of polyethylene, 1-5 parts of epoxypropane phenyl ether, 5-8 parts of barium phenolic resin, 3-7 parts of 8-hydroxyquinoline, 1-5 parts of hexamine, 2-6 parts of nitrile rubber, 2-8 parts of tricresyl phosphate, 1-5 parts of aluminium oxide, 1-4 parts of polysulfide rubber, 1-3 parts of attapulgite, 2-5 parts of polyvinyl butyral, 3-7 parts of diethylenetriamine, 2-9 parts of ethanediamine, 5-15 parts of triethanolamine and 10-20 parts of acetone. The preparation method comprises the following steps of mixing the constituents except polyvinyl butyral, heating and then adding polyvinyl butyral, and cooling to obtain the metal adhesive. The metal adhesive disclosed by the invention is short in positioning time, good in storage stability, and good in adhesion performance.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to an adhesive for metal and a preparation method thereof. Background technique [0002] Ceramics, metals, and polymer materials are known as the three major contemporary solid materials, each of which has its own advantages. Ceramics have good corrosion resistance, mechanical strength, and insulation properties; while metals have good toughness, electrical conductivity, and ease of processing. However, the brittleness of ceramics is relatively large and the resistance to sudden temperature changes is not good, so it needs to be bonded with metals, which can effectively overcome these shortcomings. For example: especially in the field of aerospace, such as the connection of key components of aircraft and missiles. [0003] Adhesive refers to a class of organic or inorganic, natural or synthetic substances that can connect the same or two or more homogeneous or hetero...
