Organic silicon rubber high in thermal conductivity

Abstract

The invention discloses organic silicon rubber high in thermal conductivity. The organic silicon rubber is prepared from, by weight, 100 parts of methyl vinyl silicone rubber, 4-6 parts of siloxane, 18-30 parts of methyl silicone oil, 5-8 parts of vinyl silicone oil, 3-15 parts of calcium carbonate, 4-16 parts of silicon dioxide, 3-5 parts of a silane coupling agent, 50-80 parts of gas-phase white carbon black, 5-15 parts of a cross-linking agent, 2-8 parts of kieselguhr and 3-10 parts of nanometer zirconia. The organic silicon rubber is non-toxic and harmless, environment friendly, highly conductive, resistant to high temperature of 250DEG C, good in weather fastness and good in breathability.

Description

technical field [0001] The application belongs to the technical field of silicone rubber, and in particular relates to a high thermal conductivity silicone rubber. Background technique [0002] Among many synthetic rubbers, silicone rubber is one of the best. It is odorless, non-toxic, not afraid of high temperature and can withstand severe cold. Ordinary silicone rubber still does not lose its original properties when it is between 200 degrees Celsius and minus 50 degrees Celsius. Strength and elasticity, at the same time, silicone rubber also has good electrical insulation, oxygen resistance and aging resistance, light resistance and aging resistance, mildew resistance, chemical stability, etc., so it is widely used in aerospace, automobiles, ships, office Supplies, electronics and other industries. However, with the rapid development of scientific and technological innovation and the rapid development of the electronic power industry, the volume of electronic products is...

Problems solved by technology

However, with the rapid development of scientific and technological innovation and the rapid development of the electronic power industry, the volume of electronic products is getting smaller and higher, and the integration level is getting higher and higher, so the heat conduction requirements for electronic components are getting higher and higher. However, the current domestic common The thermal conductivity of silicone rubber is generally not ideal, and silicone rubber with good thermal conductivity can only be imported from abroad, which is expensive
