Abstract

Provided is a room temperature and humidity thickening thermo-conductive silicone grease composition with high shape retention characteristics and good workability despite a low viscosity in an initial phase. Essential components of the room temperature and humidity thickening thermo-conductive silicone grease composition of the present invention are: (A) organopolysiloxane with a viscosity of between 0.1Pa°s and 1,000Pa°s at 25°C with both ends being blocked by a hydroxyl group; (B) organopolysiloxane represented by general equation (1) (1) (R1 is independently a substituted or non-substituted monovalent hydrocarbon group, R2 is independently an alkyl group, alkoxy alkyl group, alkenyl group, or acyl group, n is an integer between 2 and 100, and a is an integer between 1 and 3); (C) a silane compound which contains at least three hydrolysable groups bonded to a silicon atom in one molecule and / or a (partial) hydrolyzate or a (partial) hydrolysis condensate thereof; (D) a thickening catalyst; (E) a thermally conductive filler with a thermal conductivity of at least 10W / m°°C; and (F) silica fine powder.

Description

technical field

[0001] The present invention relates to a room-temperature humidity-increased thermally conductive silicone grease composition that is easy to apply and has very high shape retention properties, so that workability is very good. Background technique

[0002] In the electrical and electronic field and the conveyor field, etc., in order to precisely control the energy used, a large number of electronic components and parts have been mounted in the past. For example, even if we only focus on conveyors, electronic components and parts such as motors, inverters, and batteries that are not required for automobiles have been required to be installed due to the change from automobiles to hybrid vehicles, plug-in hybrid vehicles, and electric vehicles. In addition, in the body system such as engine control, power train, and air conditioning control, the content of control is also advanced, and the number of systems required for control is also increasing. Along with ...
