NOVELTY - Heat-conducting insulating carbon fiber silica gel gasket comprises substrate. The substrate is carbon fiber heat-conducting silica gel gasket. The carbon fiber heat-conducting silica gel gasket comprises upper surface and lower surface. The upper surface and the lower surface are respectively scraped with boron nitride dispersion to form at least one boron nitride nano-insulating layer arranged on the upper surface and the lower surface of the carbon fiber heatconducting silica gel gasket in parallel along the scraping direction. USE - Used as heat-conducting insulating carbon fiber silica gel gasket. ADVANTAGE - The gasket: improves the heat conducting of the heat conducting insulating carbon fiber silicone gasket; and meets the needs of high thermal conductivity and insulation application scenarios with large heat flow density and high insulation requirements. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the gasket, comprising adding carbon fiber, heat conducting powder, silicone oil, coupling agent, curing agent, and inhibitor to the homogenizer and uniformly mixing, adding the catalyst for uniform mixing to obtain mixed base material, adding the above-mentioned mixed base material to the glue storage barrel in the automatic glue dispenser, placing the glue storage barrel and the base material together in the vacuum box for vacuum processing, mounting the glue storage barrel on the automatic glue dispenser after the vacuum is over, starting the device, arranging the mixed base material in predetermined direction in fixed mold according to predetermined procedure, placing the mixed base material and the molding together in the oven for curing to obtain heat conducting silica gel blank, using cutting device to cut the above-mentioned heat-conducting silica gel embryo body, where the angle between the cutting direction and the predetermined direction is 50-90 degrees to obtain carbon fiber heat-conducting silica gel gasket, mixing the hydrogen-containing silicone oil, volatile organic solvent, coupling agent, inhibitor and catalyst at room temperature, preparing the boron nitride dispersion after the boron nitride is uniformly dispersed, coating the above-mentioned boron nitride dispersion liquid on the upper surface of the carbon fiber heat-conducting silicone gasket using blade coating device, forming at least one layer of boron nitride nano-insulating layer arranged on the upper surface of the carbon fiber thermally conductive silicone gasket in parallel along the squeegee direction after heating and curing, following the same steps to scrape the boron nitride dispersion on the lower surface of the carbon fiber thermal conductive silicone gasket, forming at least one layer of boron nitride nano-insulating layer arranged on the lower surface of the carbon fiber heat-conducting silicone rubber gasket in parallel along the squeegee direction to obtain the heat-conducting and insulating carbon fiber silica gel gasket after heating and curing.
