Water resistance metal binder and preparation method thereof

Abstract

The present invention provides a water resistance metal binder and a preparation method thereof, wherein the binder comprises methyltriethoxysilane, ethyl silicate, an alpha-cyanoacrylate glue, a bisphenol F epoxy resin, an E-39 epoxy resin, p-hydroxybenzenesulfonic acid, hydroxyethyl cellulose, sodium alginate, cobalt boroacylate, nanometer titanium dioxide, barium sulfate, calcium lactate, calcium citrate, tetrapod-like zinc oxide crystal whisker, ethanol, dilute hydrochloric acid and water. The preparation method comprises: stirring methyltriethoxysilane, ethyl silicate and ethanol at a temperature 75-85 DEG C, adding a mixing solution of dilute hydrochloric acid and water, adding other components excluding p-hydroxybenzenesulfonic acid after the solution is clarified, heating to a temperature of 45-55 DEG C, carrying out thermal insulation for 15-30 min, adding p-hydroxybenzenesulfonic acid, heating to a temperature of 120-140 DEG C, and maintaining for 2-3 h. According to the present invention, the metal binder has characteristics of high binding strength and water resistance, and does affect the connection after the instrument contacts water even is soaked in water; and the preparation method has characteristics of simple steps, easy control, easy industrial production, and low production cost.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a water-resistant metal adhesive and a preparation method thereof. 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; ...

AI Technical Summary

Problems solved by technology

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 and fix, and when the thickness of the metal shell is thin, it will affect the product. The appearance and follow-up treatment; 3. Using adhesives, the bonding strength of this method is not high, and it is easy to fall off when exposed to water
