Abstract

The invention discloses high-radiation heat-radiating and heat-conducting plastics and a preparation method thereof. The high-radiation heat-radiating and heat-conducting plastics are prepared from the following components: 45 to 50 percent of liquid crystal macromolecular polymers, 1 to 2 percent of nano single-arrow diamond-type graphene microsheets, 45 to 50 percent of filler, 1 to 2 percent of glass fibers, and 0.1 to 1 percent of coupling agent, wherein the filler is mixed powder of nitrides and nano oxides. The high-radiation heat-radiating and heat-conducting plastics are good in mechanical performance, high in structural force and adaptive to the market demand.

Description

technical field [0001] The invention relates to a high-radiation heat-dissipating heat-conducting plastic, in particular to a plastic material capable of enhancing the dual effects of radiation heat dissipation and high heat conduction and a preparation method thereof. Background technique [0002] Thermally conductive plastics refer to a class of plastic products with relatively high thermal conductivity, generally greater than 1W / (m.K). Most metal materials have good thermal conductivity and can be used in radiators, heat exchange materials, printed circuit boards, etc., but the corrosion resistance of metal materials limits applications in some fields, such as exchangers in chemical production and wastewater treatment , heat pipe, etc. Plastics have good corrosion resistance and mechanical properties, but compared with metal materials, plastic materials have poor thermal conductivity. The low thermal conductivity of plastics limits its range of applications. [0003] W...

Problems solved by technology

[0005] At present, the thermally conductive fillers commonly used in thermally conductive plastics are aluminum nitride, silicon nitride, boron nitride, aluminum oxide, magnesium oxide, silicon oxide, etc. These high thermal conductivity materials all use conduction as the heat transfer medium. Uneven distribution or excessive heat energy When the load is too large, the heat energy often cannot meet the heat dissipation capacity of the plastic
