Abstract

The invention provides a metal adhesive. A preparation method comprises the following steps: 1, stirring methyl trimethoxy silane, ethyl silicate, sodium silicate and ethanol at 75-85 DEG C, slowly adding a mixed liquid of the diluted hydrochloric acid and water, and clarifying the solution; 2, adding polyamide, a branched polyether epoxy resin, an acrylic acid-itaconic acid copolymer, cis-butenedioic acid dibutyl ester, polyitaconic acid, polycrotonic acid, cobalt boroacylate, polyanionic cellulose, sodium poly-maleate, nano aluminum oxide, polyacrylic acid triethanolamine and silicon carbidecrystal whisker, heating to 45-55 DEG C, and keeping the temperature for 15-30 minutes; 3, adding p-hydroxy benzenesulfonic acid, heating to 120-140 DEG C, and keeping the temperature for 2-3 hours.The metal adhesive provided by the invention is good in adhesion property, relatively good in impact resistance, shearing resistance and tensile strength and relatively good in water resistance, acidresistance, alkali resistance and temperature resistance, and the connection property of the metal adhesive is not affected even if an instrument is wetted or soaked in water.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a metal adhesive. Background technique [0002] With the development of society and the improvement of scientific and technological level, more and more precision instruments are manufactured, and people need more and more accurate scientific data to prove problems. This is also a major test for the manufacture of precision instruments. People have higher and higher requirements for the strength of materials. Most products are made of metal materials, such as aluminum alloy, stainless steel, zinc alloy, etc. The metal material has the advantages of high strength, thin thickness, fast heat dissipation, and good texture. But how to realize fast and effective connection between metals is a problem to be improved at present. At present, it is mainly through: 1. Screw hole or buckle structure, this method has more processes and is expensive; 2. Welding, this method is complicated to clamp a...
