| 摘 要： | 以聚酰胺6（PA6)为基体，以氮化硼（BN）、氧化镁（MgO）为导热填料制备了PA6/BN/MgO导热复合材料。固定填料含量为50%（质量分数，下同）不变，考察MgO/BN配比的变化对复合材料热导率、力学性能和熔体流动性的影响。结果表明，材料的热导率、拉伸强度和弯曲强度随着MgO/BN配比的增大而减小，冲击强度和断裂伸长率随着MgO/BN配比的增大而增大，材料熔体流动性则呈现了随MgO/BN配比的增大先增大后减小的趋势。

| Abstract: | Thermally conductive composites were prepared with the polyamide 6（PA6）as matrix and hexagonal boron nitride（BN）and magnesium oxide（MgO）as fillers.Keeping the dosage of fillers at 50%, the effect of weight ratio of MgO to BN, thermal conductivity（λ）, mechanical properties, melt flow rate was studied. With increasing weight ratio of MgO to BN，thermal conductivity，tensile strength, and blending strength of the composites increased，while the impact strength and elongation at breaking decreased. Besides, the melt flow rate increased first, and then reduced. |
