Abstract

The invention relates to a stable metal binder, which is prepared from the following raw materials in parts by weight: 5-11 parts of ethyleneglycol dimethacrylate, 6-11 parts of polyvinyl butyral, 2-9 parts of ethylenediamine, 5-7 parts of hydroxyquinoline, 6-8 parts of diethylenetriamine, 4-9 parts of butadiene-acrylonitrile rubber, 2-8 parts of ferric acetylacetonate, 2-6 parts of quinhydrone, 5-8 parts of fumed silica, 8-14 parts of hydrophobic modified aluminum particles, 3-6 parts of calcium carbonate, 4-7 parts of polymethyl methacrylate, 3-5 parts of copper oxide, 7-10 parts of ethyleneglycol dimethacrylate, and 5-10 parts of hexamine. The stable metal binder has the beneficial effects that the stable metal binder is good in cohesiveness and high temperature resistance, and the stable binder has good binding power at high temperature.

Description

technical field [0001] The present invention relates to a stable metal adhesive. Background technique [0002] Metal adhesive is a one-component, low-viscosity, transparent, fast-curing adhesive at room temperature. Also known as metal glue. It has a wide bonding surface and has good bonding ability to most materials. It is one of the important room temperature curing adhesives. The disadvantages are that the reaction speed is too fast, the water resistance is poor, the brittleness is large, the temperature resistance is low (<70 ℃), the shelf life is short, and the durability is not good. It is suitable for metal bonding on the market, especially for alloy metal bonding. There are fewer types of adhesives. Therefore, there is a need for an adhesive with a wide range of applications and strong cohesion. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a stable me...
