Problems solved by technology

[0004] However, most of the existing heat-conducting plastics use non-high-temperature-resistant materials as base materials, so the thermal conductivity of the products produced is not high.
Moreover, thermally conductive plastics in the domestic market are basically added with fibers, such as: self-adhesiv

Abstract

The invention discloses an insulated polyphenylene sulfide high thermal conductive plastic which is prepared from the following raw materials in percentage by mass: 30-45 parts of polyphenylene sulfide, 41-61 parts of thermal conductive agent, 3-4 parts of self-made modifying agent, 1.5-3 parts of solubilizer, 1-3 parts of lubricating agent, 1-2 parts of coupling agent, 1-1.4 parts of antioxidant and 0.5-1 part of light stabilizer. The raw materials are prepared into the insulated polyphenylene sulfide high thermal conductive plastic through the steps of pre-treating, stirring, granulating, drying and the like. The thermal conductive plastic prepared by using the method has higher thermal conductivity.

Description

technical field [0001] The invention relates to a thermally conductive plastic, in particular to an insulating polyphenylene sulfide high thermally conductive plastic and a preparation method thereof. Background technique [0002] At present, the main materials of LED heat sink lamp housings on the market are aluminum heat sinks and some low thermal conductivity plastics. Although the thermal conductivity of aluminum heat sinks is high, its insulation performance makes it impossible to pass the safety test, and it is difficult to mass-produce aluminum heat sinks. [0003] As we all know, any radiator is to quickly transfer heat from the heat source to the surface of the radiator, and then spread the heat to the surrounding environment by thermal convection and thermal radiation, about 70% by thermal convection, 30% by thermal radiation, aluminum Although the thermal conductivity is high, it only solves the problem of fast heat transfer, while the heat dissipation is mainly ...
