Abstract

The invention relates to electronic and electrical materials and particularly relates to high-thermal conductivity electrical insulation cement and a preparation method thereof. The high-thermal conductivity electrical insulation cement is characterized by comprising fluorine-containing epoxy resin, resorcinol diglycidyl ether epoxy resin, carboxylic group-containing polyimide resin, 1,4-bis(2,4-diaminophenoxy)benzene, methyl tetrahydrophthalic anhydride and inorganic filler at a mass ratio of 100:(100-300):(50-150):(15-30):(100-200):(200-600), wherein the functional fluorine-containing epoxy resin is fluorine-containing bisphenol A epoxy resin, and the structural formula is shown in the specification. The electrical insulation cement has good thermal conduction and high heat resistance, is simple in preparation method and low in cost, has an excellent electrical insulation property, facilitates large-scale batch production, is widely applicable and has a good market prospect.

Description

technical field [0001] The invention relates to electronic and electrical materials, in particular to a high thermal conductivity electrical insulating adhesive and a preparation method thereof. Background technique [0002] With the development of electrical and electronic business and the improvement of electrical and electrical technology, the wide application of high-performance electrical and electronic products and other high-performance technological products will inevitably generate more heat. If these heat cannot be exported, it will seriously affect The performance of the product will shorten the service life of the product, and if it is used for a long time, it may cause a safety accident. Therefore, insulating polymer materials in the electrical and electronic industries urgently need materials with high thermal conductivity to ensure stable and safe operation. [0003] At present, the production of insulating polymer materials generally involves adding high the...
