Novel graphite composite material

Abstract

The invention discloses a novel graphite composite material. The novel graphite composite material is characterized by comprising graphite base layers and gummed layers, wherein the graphite base layers are mutually stacked; one gummed layer is arranged between every two adjacent graphite base layers; the outer surfaces of the gummed layers and the graphite base layers are coated with UV ink films; and metal coatings are located on the outer surfaces of the UV ink films. The novel graphite composite material has the advantages that the graphite base layers are mutually stacked, and the gummed layer is arranged between every two adjacent graphite base layers, so that the thickness of the composite material can be effectively increased and the heat-conduction and heat-dissipation effects are enhanced. According to the novel graphite composite material, the outer surfaces of the gummed layers and the graphite base layers are coated with the UV ink films, and the outer surfaces of the UV ink films are coated with the metal coatings, so that the integral strength of the graphite composite material is enhanced and the connection strength of the graphite composite material and metal substrates of other radiators is enhanced.

Description

technical field [0001] The invention relates to a composite material, in particular to a novel graphite composite material. Background technique [0002] Thermally conductive materials are widely used in various sectors of the national economy and industrial fields. With the advancement of industrial development and technology, people put forward more new requirements for thermal conductive materials, such as electrical insulation, corrosion resistance, light weight, easy processing and molding, etc. High-tech electronic products are developing in the direction of small, light and thin, and the number of integrated electronic components is increasing, and the heat dissipation problem needs to be solved urgently. [0003] During the use of electronic components, due to the heat generated inside the components, which cannot be dissipated, it is easy to cause relatively extreme temperatures in the system and cause damage to the devices themselves. Therefore, electronic compone...

Problems solved by technology

However, due to the limitation of traditional technology, the thickness of polymer graphite cannot exceed 0.1-0.25mm, which affects the thermal conductivity and heat dissipation performance of polymer graphite as a heat-conducting and heat-dissipating material.
