PA10T composite heat radiation material for heatproof LED lamp and preparation method thereof

The invention provides a PA10T composite heat radiation material for heatproof LED lamp, and the material is prepared from the following raw materials in part by weight: 40-42 parts of magnesium oxide, 20-22 parts of boron nitride, 2-3 parts of short cut glass fibre, 30-32 parts of polyamide PA10T, 7-8 parts of alumina whisker, 1-2 parts of carbon monofluoride, 2-3 parts of BeC, 1-2 parts of aluminium nitride, 3-4 parts of zirconium silicate powder, 2-2.5 parts of polyvinyl butyral, 5-6 parts of ethanol and 3-4 parts of SEBS. The composite heat radiation material provided by the invention employs boron nitride to modify SEBS, so that the notch impact strength of the material is improved; the material provided by the invention employs short cut glass fibre and whisker for modification, so that the heat conduction coefficient and mechanical properties of the composite material are improved, and the electrical property is maintained at a high level; carbon monofluoride is used, and the thermal diffusivity, the waterproof and oil resistant function are improved; BeC, aluminium nitride and zirconium silicate powder are used, so that the material has an excellent heat conduction performance, and the hear resistance of the material is improved.
