Problems solved by technology

With the development of electronic and electrical technology, various electronic components, electronic products, and electrical equipment are required to integrate more powerful functions into smaller components. In order to make products safer, more optimized, and more perfect, many Designers have tried their best to do this, but due to the relatively simple physical properties of existing silicone rubber, for example, flame-retardant silicone rubber has no thermal conductivity, while thermally conductive silicone rubber has no flame retardancy and better weather resis

Abstract

The invention discloses organic silicon rubber, which has flame retardance, high heat conductivity, high temperature resistance and low temperature resistance and can be used for replacing the conventional organic silicon rubber. The organic silicon rubber comprises alpha,omega-divinyl polydimethylsiloxane, methyl hydrogen-containing polysiloxane, cerium oxide, zinc oxide, ferric oxide, alumina, hydroxyl ferric oxide, white carbon black, a catalyst and an aid in the weight ratio of (10-18):(1-6):(1-1.25):(5-25):(1-3):(10-12.5):(1-2.5):(10-25):(1-2.5):(0.003-1.25):(0.003-1.25).

Description

【Technical field】 [0001] The invention relates to a silicone rubber and a production method thereof, in particular to an addition-type silicone rubber with flame retardancy, high thermal conductivity, high temperature resistance and low temperature resistance and a preparation method thereof. The silicone rubber of the invention can replace the traditional Organic silicon rubber belongs to the technical field of organic silicon chemical industry. 【Background technique】 [0002] In recent years, silicone rubber materials have been widely used in the electronic and electrical industry, but because they are polymer materials, they are flammable and have a large amount of smoke, and sometimes they are the direct fuse of fire; therefore, flame-retardant silicone rubber has gradually Become the main force of silicone rubber materials in the electrical and electronic industry With the development of industrial production and science and technology, people continue to put forward ne...
