Abstract

The invention provides a novel non-metal high-thermal-conductivity composite material which is prepared from the following raw materials in parts by weight: 5-20 parts of a carbon elementary substance nano material, 30-45 parts of graphite micro powder and 50-80 parts of macromolecular resin, the sum of the total amount of the carbon elementary substance nanometer material and the total amount of the graphite powder does not exceed 50% of the high-thermal-conductivity composite material. Existing aluminum alloy materials are widely designed and applied to heat conduction and heat dissipation bodies, but aluminum as a heat conduction and heat dissipation base material has the defects of huge energy consumption, poor processing environment, serious pollution, high probability of explosion and the like in the processing process and the use process of the aluminum as the heat conduction and heat dissipation base material; and according to the invention, the carbon elementary substance nano material and the graphite micro powder are adopted, the heat dissipation performance of a high polymer material is effectively improved, preparation of a non-metal high-thermal-conductivity composite material is achieved, and aluminum materials are effectively replaced for production of radiators.

Description

technical field [0001] The invention relates to a non-metallic heat-conducting and heat-dissipating material filled with carbon simple substance and a molding process of the material; specifically, a material composite prefabrication technology is used to fully mix carbon simple substance and phenolic resin and prefabricate fluffy particles or blocks, and pass A mold with a certain shape, high temperature and high pressure are applied in the mold cavity, and the prefabricated particles / blocks are compressed and solidified alone or combined with other structural materials. The prefabricated material undergoes a chemical reaction under high temperature and high pressure, and at the same time, the texture changes from fluffy to dense, and forms a high thermal conductivity. Background technique [0002] Existing aluminum alloy materials are widely designed and applied in heat conduction and heat dissipation bodies. Through the movement of its free electrons, metals can quickly ...
