【摘要】研究了碱式硫酸镁(M-HOS)和钛酸钾(K2Ti6O13)晶须填充改性PP热变形温度、流动性能和力学性能等。结果表明,这两种晶须均能有效地提高PP热变形温度,同时也能改善其力学性能。镁盐和钛酸钾晶须的最佳含量均为30%,此时PP热变形温度分别提高到151.8℃和146.5℃。更多还原

【Abstract】 Heat deformation temperature（HDT）,fluidity and mechanical properties of polypropylene（PP） modified by M-HOS and K₂Ti₆O₁₃ whiskers were studied.Experimental results showed that the whiskers could increase the HDT of PP evidently,and they also improved the mechanical properties of PP.When the content of M-HOS whiskers was 30%,the HDT of PP was 151.8℃,and as the content of K₂Ti₆O₁₃ whiskers was 30%,the HDT of PP was 146.5℃.更多还原
