【摘要】 探讨了纳米氧化镁粒子对PC/ABS合金力学性能和刮擦性能的影响.结果表明添加纳米MgO粒子后,PC/ABS合金的拉伸、弯曲和缺口冲击强度及表面耐刮擦性能都得到了部分改善;当纳米MgO添加量为7%时,PC/ABS合金的综合力学性能和耐刮擦性能最优,其中弯曲强度最大值比未加填料提高10%,缺口冲击强度可提高7%.刮擦面电镜表明PC/ABS合金耐刮擦性能得到明显改善.更多还原

【Abstract】 The effect of nano-MgO particles on mechanical properties and scratch-resistant behavior of PC/ ABS blends were investigated in this article.The results showed that addition of nano-MgO particles improved the tensile and flexural strength,notched izod impact strength and scratch-resistant of PC/ABS blends.The optimum mechanical properties and scratch-resistant of PC/ABS blend were obtained at the content of nano-MgO particles of 7%and the flexural strength and notched izod impact strength increased by 10%and 7%,respectively compared to unfilled blends.The results in SEM indicated that addition of nano-MgO particles improved the the scratch-resistant capacities of PC/ABS blends and the scratch-resistant behavior.更多还原
