Abstract

A PBT heat-conducting and heat-resistant material for LED lamp holders and a preparation method thereof, relating to a heat-resistant plastic material and a preparation method thereof, the heat-conducting and heat-resistant PBT mainly consists of a resin matrix, a reinforcement system, a heat conduction system, and a lubrication system , Composition of antioxidant system. Among them, the resin matrix is ​​PBT; the reinforcement system is glass fiber; the lubrication system is TAF lubricant and calcium stearate; the antioxidant system is antioxidant 1010. The thermally conductive and heat-resistant PBT material prepared by the present invention uses glass fiber as a reinforcing skeleton, uses ethylene-methyl acrylate-glycidyl methacrylate terpolymer (E-MA-GMA) as a compatibilizer, and is filled with AlN. The thermal conductivity factor maintains good strength and toughness while ensuring the high thermal conductivity of the PBT material. At the same time, the advantages of PBT plastics such as easy processing and low mass production cost can make the thermal conductive plastic used in LED lamp holders and other related fields.

Description

technical field [0001] The invention relates to a heat-resistant plastic material and a preparation method thereof, in particular to a PBT heat-conducting and heat-resistant material used for an LED lamp holder and a preparation method thereof. Background technique [0002] With the global warming caused by greenhouse gas emissions, people have enhanced their awareness of energy conservation and environmental protection. The use of new energy-saving light-emitting diodes (Light Emitting Diode, referred to as LED) has attracted the attention of the international community. Since light-emitting diodes (LEDs) have the advantages of small size, high luminous efficiency, low energy consumption, high brightness, and environmental protection, governments of various countries have increased funding and corresponding policy support for LED research and development. In the past decade, LED technology has developed rapidly. In 2010, Europe has banned high-power incandescent lamps, co...
