Heat-dissipation graphite powder mixed plastic material

Abstract

The invention discloses a heat-dissipation graphite powder mixed plastic material which comprises thermoplastic or thermosetting plastics. Heat-dissipation graphite powder, which accounts for 20-60 wt%, is uniformly mixed in the thermoplastic or thermosetting plastics. Since the heat-dissipation graphite powder is added into the plastic material disclosed by the invention, the particles of the graphite powder are orderly arranged to some extent to form microchannel carbon tubes, and each heat-dissipation channel is composed of a plurality of microchannels, thereby generating the chimney effect. When being installed on the surface of a heat source, the plastic material has favorable heat-dissipation performance. When being mixed in the plastic material, the graphite powder can modify the plastic material, so that the plastic material has favorable coefficient of heat transfer, and has the effects of shielding electromagnetic waves, blocking secondary radiation and the like.

Description

A plastic material mixed with heat-dissipating graphite powder technical field The invention relates to a plastic material mixed with heat-dissipating graphite powder. Background technique With the development of science and technology and people's needs, more and more electronic products are used, and there are various requirements for new materials. For example, it is hoped to obtain plastics with better heat dissipation effects in applications, so as to realize It has the advantages of light weight, good heat dissipation effect, and easy processing. However, as far as the current situation is concerned, the existing technology is not ideal. On the other hand, for various types of electronic products, it is also hoped that new materials that can effectively prevent the influence of electromagnetic waves can be obtained. Contents of the invention In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a plastic mater...
