Problems solved by technology

Under normal circumstances, the running time of the computer is very long. The computer fan rotates for a long time and the fan blades rub against the air to generate a large amount of positive and negative charges. There is too much electrostatic adsorption on the computer fan, which not only affects the normal operation of the computer fan, but also shortens the use of the fan. At the same time, the electrostatically adsorbed dust on the computer fan is transferred to other adjacent electronic components, which will also affect its service life

Abstract

The invention belongs to the technical field of computer material, and provides an antistatic computer fan composite material. The antistatic computer fan composite material comprises the following raw materials in parts by weight: 53-60 parts of polytetrafluoroethylene, 12-20 parts of graphene reinforcing fibers, 13-20 parts of organic fibers, 6-11 parts of conductive polymers, 2-7 parts of diffusing oil, 2-5 parts of a fire retardant , 1-3 parts of zinc-copper alloy, and 1-5 parts of plasticizer. The polytetrafluoroethylene is used as a main material of the antistatic computer fan composite material, auxiliary materials including the conductive polymers, the diffusing oil, the fire retardant, the zinc-copper alloy, the plasticizer and the like are added, and therefore, the compressive strength, the toughness and the antistatic property of the composite material are improved.

Description

technical field [0001] The invention belongs to the technical field of computer materials, in particular to an antistatic computer fan composite material. Background technique [0002] Plastic based products are also popular for their corrosion resistance, light weight, low cost and ease of installation. However, the strength of plastic raw materials is low, relatively flammable, and products made of them are also prone to static electricity, so the performance of plastic materials still needs to be improved. [0003] Existing computer fans that adopt plastic raw materials to make also have the problem of dust absorption caused by static electricity. Under normal circumstances, the running time of the computer is very long. The computer fan rotates for a long time and the fan blades rub against the air to generate a large amount of positive and negative charges. There is too much electrostatic adsorption on the computer fan, which not only affects the normal operation of th...
