The invention discloses a silica gel foam material with heat-conducting property and a preparation method, and relates to the technical field of silica gel foam materials, the silica gel foam material comprises the following components: 100 parts of organic silica gel, 20-30 parts of a reinforcing agent, 0.2-0.5 part of a vulcanizing agent, 2-8 parts of a foaming agent, and 2-5 parts of a foaming promoter, 0-10 parts of a conditioning agent, 10-20 parts of a flame retardant, 2-5 parts of a carbon nanotube high-thermal-conductivity filler and 2-5 parts of nano oxide. According to the silica gel foaming material with the heat-conducting property, the carbon nano tubes have good heat transfer performance, and the CNTs have a very large length-diameter ratio, so that the heat exchange performance of the silica gel foaming material in the length direction is very high, the heat exchange performance of the silica gel foaming material in the vertical direction is relatively low, and the thermal conductivity of the silica gel foaming material is greatly improved through proper orientation. The carbon nanotubes can be used for synthesizing a heat conduction material with high anisotropy, in addition, the carbon nanotubes have higher heat conductivity, and the heat conductivity of the silica gel foaming material is greatly improved by doping a trace amount of carbon nanotubes into the silica gel foaming material.
Description
technical field [0001] The invention relates to the technical field of silica gel foam materials, in particular to a silica gel foam material with thermal conductivity and a preparation method. Background technique [0002] Foamed silica gel is a two-component heating vulcanized silicone rubber, which is a white or skin-colored oily liquid. After vulcanization, it becomes a soft elastic material. The foaming volume is 3-4 accompany the original; Pads, patches, anti-skid pads and other flexible silicone rubber products. [0003] The silicone foam materials in the prior art are generally not resistant to high temperatures, have poor thermal conductivity, and cannot withstand high temperatures for a long time after molding, resulting in deformation. Therefore, it is necessary to design a silicone foam material with thermal conductivity to solve the problem. above problem. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to solve the shortcomings in ...
