Description

technical field [0001] The invention relates to the technical field of computer heat dissipation, in particular to an anti-cracking computer heat-conducting silicone grease and a preparation method thereof. Background technique [0002] Thermally conductive silicone grease is commonly known as heat dissipation paste. Thermally conductive silicone grease is made of organic silicone as the main raw material, and materials with excellent heat resistance and thermal conductivity are added to form a thermally conductive silicone grease compound. It is used in power amplifiers, transistors, electronic tubes and other electronic components. The heat conduction and heat dissipation of the original device, so as to ensure the stability of the electrical performance of electronic instruments and meters. When the computer is working, the CPU and GPU will generate a lot of heat. In order to prevent the high temperature from affecting the performance, the CPU and GPU generally coat a lay...

AI Technical Summary

Problems solved by technology

[0003] The existing thermal conductive silicone grease can generally meet the basic needs of heat conduction, but the thermal conductive silicone grease will gradually dry out after a period of use, resulting in a significant decrease in thermal conductivity. At this time, it is necessary to replace the thermal conductive silicone grease. It is more troublesome for people with poor ability. Many users have not replaced the thermal grease after using the computer for a long time, which causes some hardware of the computer to always be in a high temperature working state, which affects the overall performance and service life of the computer.
