Crystal whisker reinforced organic silicon heat conducting material and preparation method thereof

Abstract

The invention discloses a crystal whisker reinforced organic silicon heat conducting material and a preparation method thereof. The crystal whisker reinforced organic silicon heat conducting material is prepared from organic silicon resin, heat conducting insulating filler, crystal whiskers, a platinum catalyst, hydrogen-containing silicon oil, a coupling agent and other additives which are subjected to processes such as surface treatment, vacuum smelting and rolling. By adding the inorganic crystal whiskers and the heat conducting insulating filler, the heat conductivity coefficient of the organic silicon material can be increased, the mechanical properties of the organic silicon material can be improved as well, and the organic silicon material has better toughness and more balanced mechanical properties and can be widely applied to electronic heat conduction fields of electrons, automobiles, LED lamps and the like.

Description

technical field

[0001] The invention relates to a whisker-reinforced organosilicon heat-conducting material and a preparation method thereof, belonging to the technical field of organosilicon polymer materials. Background technique

[0002] Silicone products are based on silicon-oxygen (Si-O) bonds as the main chain structure, so silicone products have the characteristics of high thermal stability, high weather resistance, electrical insulation performance, low surface tension and low surface energy, and physiological inertia. , due to the above-mentioned excellent properties of silicone, its application range is very wide. It is not only used as a special material in aviation, cutting-edge technology, and military technology departments, but also in various sectors of the national economy. Its application range has expanded to: construction, electronics, textiles, automobiles, machinery, leather and paper, chemical industry Metals and paints, medicine and medical treatment...
