本发明涉及导热塑料。该导热塑料的配方按质量份计包括以下组分：尼龙66 55-65份、钢纤维10-18份、无卤聚磷酸含氮化合物18-22份、硅油1-3份、硅微粉1 - 3份、抗氧剂1098 0.5-2份，或者按质量份计包括以下组分：尼龙66 58-68份、铝纤维7-15份、无卤聚磷酸酯含氮化合物18-22份、硅油1-3份、硅微粉1 - 3份、抗氧剂1098 0.5-2份。该导热塑料的导热系数为5- 15 W/m.K，阻燃性能为V-0级，绝缘性能通过欧盟安全测试（即绝缘性能≥ 3750 V），机械性能优于尼龙66产品，生产成本适中，从而适用于LED灯具散热系统，以替代铝壳，也可应用于其他电子电器产品。
The invention relates to thermal conductive plastic. A formula of the thermal conductive plastic comprises the following components in parts by mass: 55-65 parts of nylon 66, 10-18 parts of steel fiber, 18-22 parts of halogen-free poly-phosphate nitrogenous compound, 1-3 parts of silicone oil, 1-3 parts of silicone powder and 0.5-2 parts of antioxidant 1098, or comprises the following components in parts by mass: 58-68 parts of nylon 66, 7-15 parts of aluminium fiber, 18-22 parts of halogen-free poly-phosphate nitrogenous compound, 1-3 parts of silicone oil, 1-3 parts of silicone power and 0.5-2 parts of antioxidant 1098. The thermal conductive plastic has the advantages that thermal conductivity is 5-15W/m.K, flame retardant property is at a level V-0, insulating property passes a safety test in European Union (namely the insulating property is higher than or equal to 3750V), mechanical property is better than that of a nylon 66 product, and production cost is moderate, so that the thermal conductive plastic is applicable to an LED lamp cooling system, so as to replace an aluminium shell, and the thermal conductive plastic also can be applied to other electronic and electrical products.
