摘要： 制备了PP（聚丙烯）/Al(OH)3/Mg(OH)2导热复合材料，并用稳态平板导热系数测试仪在不同测试温度下测定该复合材料的导热系数。结果表明，加入Al(OH)3和Mg(OH)2使PP导热系数提高。复合材料的导热系数随着填料含量的增加而非线性提高，随着测试温度的升高而非线性提高，随着填料粒径的增大而非线性增大。

Abstract: Polypropylene (PP) thermal composites filled with Al(OH)3 and Mg(OH)2 were prepared. The thermal conductivity coefficient of the composites was measured by stable flat measuring instrument for thermal conductivity in different testing temperature. The addition of Al(OH)3 and Mg(OH)2 resulted in the thermal conductivity increase of PP. The thermal conductivity coefficient of PP/Al(OH)3/Mg(OH)2 composites presents a nonlinear increase with the increase in filler content，with the increase in testing temperature，as well as with the increase in filler diameter.
