However, with the use of a large number of functional fillers such as thermal conductivity and mechanical strength, although functions such as thermal conductivity can be well realized, these thermal conductive silica gels are high-density. As the weight of new energy vehicles increases, its application in new energy vehicles is limited. Widely used in automobiles

Abstract
The invention discloses a low-specific-weight heat-conducting silica-gel gasket for a new-energy vehicle. The low-specific-weight heat-conducting silica-gel gasket is prepared from the following components in parts by weight: 100 parts of organopolysiloxane, 200-2000 parts of high-heat-conductivityinorganic filler, 0-50 parts of lightweight filler, 0.05-0.5 part of catalyst and pigment, wherein the organopolysiloxane is a composition of vinyl polysiloxane and hydrogen-containing polysiloxane; the high-heat-conductivityinorganic filler is prepared from one or more of silicon dioxide, aluminiumoxide, zincoxide, magnesiumoxide, aluminiumhydroxide, aluminiumnitride, siliconnitride, boronnitride and siliconcarbonate; the particle size of the high-heat-conductivityinorganic filler is0.1-100mu m. The low-specific-weight heat-conducting silica-gel gasket disclosed by the invention has the beneficial effects that the conventional performances of the heat-conducting silica-gel gasketcan be ensured, meanwhile the low specific weight of the heat-conducting silica-gel gasket is realized, the weight of the low-specific-weight heat-conducting silica-gel gasket under the equal heat-conductivity coefficient is 40%-70% of that of the conventional heat-conducting gasket in the prior art, and the lightweight requirement for the new-energy vehicle is met.
Description
technical field [0001] The invention relates to the technical field of heat-conducting silica gel, in particular to a low-specific-gravity heat-conducting silica gel gasket for new energy vehicles and a preparation method thereof. Background technique [0002] Thermally conductive silicone gasket is a kind of thermally conductive interface material synthesized by a special process based on silica gel, adding various auxiliary materials such as metal oxides. It is specially produced for the design scheme of using gaps to transfer heat. It can fill gaps and complete The heat transfer between the heating part and the heat dissipation part also plays the role of insulation, shock absorption and sealing, which can meet the design requirements of miniaturization and ultra-thin equipment. It is extremely manufacturable and practical, and the thickness is applicable to a wide range. It is an excellent thermally conductive filler material. [0003] However, due to the large amount o...
