Abstract

The invention discloses a heat-conducting plastic and a preparation method thereof, wherein the heat-conducting plastic comprises, by weight, 25% to 80% of matrix resins, 5% to 40% of heat-conducting fillers, 5% to 10% of coupling agents and 5% to 30% of halogen-free flame retardants. According to the heat-conducting plastic, the coefficient of heat conductivity is high, the injection molding is convenient, the cost is low, heat dissipation is even, hot spots can be avoided, local deformation of parts caused by the high temperature is reduced, the weight is light and lighter than the weight of aluminum materials by 40% to 50%, the molding processing is convenient, secondary processing is not needed, and the product design degree of freedom is high.

Description

Technical field [0001] The invention relates to the field of materials, in particular to a thermally conductive plastic and a preparation method thereof. Background technique [0002] Traditional thermal conductive materials are mostly metals such as Ag, Cu, Al and metal oxides such as Al 2 O 3 , MgO, BeO and other non-metallic materials such as graphite, carbon black, Si 3 N 4 , AlN. With the development of industrial production and science and technology, people have put forward new requirements for thermally conductive materials, hoping that materials have excellent comprehensive properties: for example, heat exchangers used in chemical production and wastewater treatment require the materials used to have thermal conductivity and It is required to be resistant to chemical corrosion and high temperature; for example, due to the rapid development of integration technology and assembly technology in the electrical and electronic field, the volume of electronic components and log...
