Abstract

The invention relates to a heatproof plastic material and a preparation method thereof, and concretely relates to a heat-conduction heatproof PBT material for LED lamp holders, and a preparation method thereof. The heat-conduction heatproof PBT is mainly composed of a resin matrix, a reinforcing system, a heat conduction system, a lubrication system and an anti-oxidation system, wherein the resin matrix is PBT; the reinforcing system is glass fibers; the lubrication system is a TAF lubricant and calcium stearate; and the anti-oxidation system is an antioxidant 1010. The heat-conduction heatproof PBT material prepared in the invention adopts the glass fibers as a reinforcing skeleton, ethylene-methyl acrylate-glycidyl methacrylate terpolymer (E-MA-GMA) as a compatibilizer and filled AlN as a heat conduction factor, so good strength and toughness are maintained on the premise of guaranteeing of the high heat conductivity of the PBT material; and the advantages of workability and low batch production cost of the PBT plastic make the heat conduction plastic be applied in LED lamp holder 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...
