摘要
首先用硫酸钙晶须、抗氧剂1010、抗氧剂168与聚丙烯通过熔融挤出制造出聚丙烯/硫酸钙晶须的复合材料。讨论含量为0、1%、2%、3%、5%硫酸钙晶须对复合材料的力学性能性能的影响,结果表明,硅氧偶联剂修饰的硫酸钙晶须含量为2%时,复合材料的拉伸强度、弹性模量以及弯曲强度最大,然而,随着硫酸钙晶须含量的增加,复合材料的冲击韧性显著降低。
The composite material of polypropylene/calcium sulfate whisker was prepared by melt extrusion using calcium sulfate whiskers,antioxidant 1010,antioxidant 168 and polypropylene. The effects of 0,1%,2%,3%,5% of calcium sulfate whiskers on the mechanical properties of the composites were studied. The results exhibited that 2% of siloxane coupling agent modified calcium sulfate whiskers treated composites had the best tensile strength,elastic modulus and flexural strength performance.However,the impact toughness of the composites decreased significantly along with the increase of calcium sulfate whiskers content.
