Abstract

The invention discloses a heat-conducting silicone grease composition which mainly consists of organic silicone oil, a silicane coupling agent and heat-conducting powder, wherein the silicane coupling agent covers the surface of the heat-conducting powder; the heat-conducting powder is prepared from powders with larger, intermediate and small diameters; and the concerned metal powder is subjected to heat treatment to form an oxide film on the surface of the metal powder. The heat-conducting silicone grease composition has high heat conductivity and good fluidity; secondarily, the heat-conducting silicone grease composition has high temperature resistance and can keep good heat conductivity and fluidity at 250 DEG C; additionally, the heat-conducting silicone grease composition requires no refrigeration and has the advantages of simplified storage and operation flows and high reliability.

Description

technical field

[0001] The invention relates to a high-temperature-resistant heat-conducting silicone grease composition. Background technique

[0002] With the continuous increase of power consumption and power density of microelectronics technology, heat dissipation has become the key to the progress of PCB board technology. The operating temperature of a single electronic component increases by 10°C, and the reliability is reduced by 50%. CPU failure due to overheating accounts for CPU failure The proportion of the total is 55%. As a result, many heat dissipation technologies and heat dissipation materials have been developed. Among them, thermal interface materials have been widely used because they can effectively reduce the interface thermal resistance between heat sources and heat sinks, and many varieties have been derived. Thermal grease is one of them. According to different application environments, silicone grease is divided into conductive and thermal conducti...
