Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that, in the heat conduction process of the equipment, the thermally conductive silicone pad is prone to softening and stress relaxation as the temperature rises after the equipment is running for a period of time. Phenomenon, resilience and tightness are reduced, therefore, the preparation of a thermally conductive silicone pad with high thermal conductivity and high resilience is a problem that needs to be solved at present

Description

technical field [0001] The present application relates to the field of heat-conducting silica gel pads, more specifically, it relates to a heat-conducting silica gel pad with high thermal conductivity and high resilience and a preparation method thereof. Background technique [0002] Thermally conductive silica gel is a kind of thermally conductive insulating compound, which is widely used in various electronic products, heating elements (power tubes, thyristors, electric heating stacks, etc.) and heat dissipation facilities (radiating fins, cooling strips, shells, etc.) The base surface between them acts as a heat transfer medium and has properties such as moisture-proof, dust-proof, corrosion-proof, cushioning and shock-proof. [0003] The thermal conductivity of the thermally conductive silicone pad determines the thermal conductivity of the thermally conductive silicone pad. The larger the thermal conductivity, the faster the thermally conductive silicone pad can absorb ...
