Abstract

The invention discloses tooth-shaped heat-conducting silicon rubber. The tooth-shaped heat-conducting silicon rubber is prepared from the following components in percentage by weight: 15%-35% of an organic silicon polymer, 40%-75% of heat-conducting powder, 1%-20% of a flame retardant and the balance of an auxiliary agent. The tooth-shaped heat-conducting silicon rubber product disclosed by the invention has the properties of heat conduction, insulation, high compression and high wearing resistance; the properties of heat conduction, insulation, large tolerance clearance, wearing resistance and piercing resistance needed by certain special fields are realized; and the preparation is simple and feasible, and the tooth-shaped heat-conducting silicon rubber is safe and reliable.

Description

technical field [0001] The invention relates to polymer technical materials, in particular to a tooth-shaped heat-conducting silicone rubber and a preparation method thereof. Background technique [0002] Heat dissipation has always been a key research task in the electronics industry, and the actual operating temperature of electronic components is one of the key factors affecting their reliability. With the development of electronic equipment towards miniaturization and high power consumption, its power consumption density gradually increases. The calorific value of electronic equipment has also increased exponentially, which also puts forward higher requirements on the heat dissipation performance of the system. The thermal interface material is the key material of the heat dissipation system, and it is the bridge connecting the heat transfer between the chip and the heat sink. According to the different fillers and production processes of thermally conductive materials...
