Description

technical field [0001] The invention relates to a two-component glue, which belongs to a two-component potting glue and a preparation method thereof. Background technique [0002] Due to its excellent electrical insulation properties, high temperature resistance and weather resistance, good chemical stability, and simple processing technology, silicone potting adhesives are widely used in electronic potting and other fields, and play a role in moisture-proof, corrosion-proof, shock-proof, and anti-corrosion. The role of dust can not only improve the performance of electronic products, but also stabilize the parameters of electronic components, but ordinary silicone potting adhesives have disadvantages such as low adhesion to the substrate and no adhesion, which seriously affects the its scope of application. Epoxy resin potting compound has strong affinity with various polar materials such as metal, glass, cement, wood, plastic, etc., especially materials with high surface ...
