Abstract

The invention relates to the technical field of LED lamp production, and discloses an abrasion-resistant LED heat dissipation lamp holder and a preparation method thereof. The abrasion-resistant LED heat dissipation lamp holder is prepared from the following raw materials in parts by weight: 60-90 parts of polyamide resin, 40-60 parts of polypropylene resin, 5-9 parts of a toughening agent, 15-20parts of an asbestos fiber, 3-6 parts of high alumina bauxite, 0.4-0.7 part of an antioxidant, 0.3-0.8 part of a lubricant, and 0.2-0.5 part of a dispersant. The LED lamp holder has good heat dissipation, abrasion resistance, flame retardancy, safety and environmental protection; polyamide resin and polypropylene resin which are heat conducting materials are taken as main raw materials; the asbestos fiber and the high alumina bauxite are added; on the premise of ensuring good heat dissipation, the mechanical strength and abrasion resistance of the LED lamp holder can be effectively improved; meanwhile, the use of toxic and harmful raw materials containing bromine and heavy metals is reduced; and compared with traditional aluminum lamp holders and ceramic lamp holders, the LED lamp holder prepared by direct injection molding of mixed powder has simple process and low costs.

Description

technical field [0001] The patent of the invention relates to the technical field of LED lamp production, in particular to a wear-resistant LED heat dissipation lamp holder and a preparation method thereof. Background technique [0002] With the increasing world energy crisis and environmental pollution, energy conservation and environmental protection have become the theme of today's social development. In the field of global power resource consumption, lighting accounts for about 20% every year. Therefore, lighting energy saving has become more and more popular among people. focus on. However, the traditional incandescent and fluorescent lamps are completely unable to meet the needs of human social development due to their low energy efficiency, short lifespan and the production of toxic substances. As a new generation of green lighting source, LED (Light Emission Diode) has been widely used in indoor and outdoor lighting, billboards, etc. , stage decoration, automobile ...
