Abstract

The invention relates to a Si-H polymer, a heat-conducting silica gel composition and a preparation method and application of the Si-H polymer and the heat-conducting silica gel composition. The Si-H polymer is obtained by carrying out condensation polymerization on hydrogen-containing silane containing 2 to 3 methoxy groups, methyl phenyl diethoxy silane and diphenyl silanediol; the molar ratio of the methoxy group in the hydrogen-containing silane to the diethoxy group in the methyl phenyl diethoxy silane to the hydroxyl group in the diphenyl silanediol is 1: (0.5-1.5): (0.25-1). The Si-H polymer is used as a cross-linking agent to be added into the components of the heat-conducting silica gel, so that the oil leakage problem of the cured heat-conducting silica gel can be effectively improved, and meanwhile, no obvious negative influence is brought to the flexibility of the heat-conducting silica gel. In addition, the oil leakage problem is effectively improved, so that the heat-conducting property of the heat-conducting silica gel is kept stable for a long time.

Description

Technical field [0001] The present invention involves the field of thermal conductivity silicon gel, and more specific, involves a SI-H pool, thermal conductivity silicon gel composition, and its preparation methods and applications. Background technique [0002] With the proposal of the national "carbon peaks" and "carbon neutralization" strategic goals, the needs of the whole society for energy conservation and emission reduction are becoming more and more urgent. Energy storage materials are "peak -cutting and filling valley" It plays an important role. New energy vehicle power batteries can be stored in energy when using the electric trough, which is conducive to the re -distribution of energy. Therefore, in recent years, new energy vehicles have been strongly supported and developed. New energy vehicle power batteries will generate heat during work. If these heat cannot be distributed in the environment in time, it will cause fatal damage to the electronic components around ...
