Abstract

The invention discloses a PBT heat conducting and heat resisting material for an LED lamp holder and a preparation method of the PBT heat conducting and heat resisting material and relates to a heat resisting plastic material and a preparation method thereof. The heat conducting and heat resisting PBT mainly comprises a resin matrix, a reinforcing system, a heat conducting system, a lubricating system and an antioxidant system; the resin matrix is PBT; the reinforcing system is glass fibers; the lubricating system comprises a TAF lubricant and calcium stearate; the antioxidant system is an antioxidant 1010. According to the heat conducting and heat resisting PBT material prepared by the preparation method disclosed by the invention, the glass fibers are used as a reinforcing framework, anethylene-methyl acrylate-glycidyl methacrylate (E-MA-GMA) terpolymer is used as a compatibilizer, and AIN is filled as a heat conducting factor; better strength and toughness are kept under the condition of ensuring high heat conductivity of the PBT material; meanwhile, the PBT plastic has the advantages of easiness in processing, batch production, low cost and the like, so that the heat conducting plastic is applied to the related fields of LED lamp holders and the like.

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. Generally, about 15% to 20% of the input power of a high-pow...
