Description

technical field [0001] The invention relates to the technical field of heat-conducting silica gel, in particular to an aging-resistant heat-conducting silica gel material for a computer processor and a preparation method thereof. Background technique [0002] A computer processor is the functional unit that interprets and executes instructions, also known as the central processing unit or cpu, which is the central nervous system of a computer, in contrast to the devices surrounding the processor and memory called peripherals, such as keyboards, monitors, Disks, tape drives, etc. are peripherals. Each processor has a unique set of operation commands, which can be called the instruction set of the processor, such as storage, transfer, etc. are all operation commands. [0003] Computer processors will generate a lot of heat during work. If the heat dissipation measures are not proper, the temperature of the components will be too high, resulting in a decrease in its working pe...
