| 摘 要： | 研究了成核剂HPN-A,HPN-B对抗冲共聚聚丙烯2500H力学性能、热性能以及收缩率的影响。结果表明:成核剂HPN-B对2500H的性能影响较大,其添加量为0.08%(质量分数)时,试样的弯曲模量和拉伸强度分别提高22%和5.4%;成核剂HPN-B在提高试样刚性的同时,使试样的简支梁缺口冲击强度也略有提高。在热加工性能方面,成核剂HPN-B提高了试样的结晶温度和负荷变形温度,使试样的横向收缩率和纵向收缩率分别缩小6.15%和8.20%。

| Abstract: | It was investigated that the influence of nucleating agent HPN-A/HPN-B on mechanical, thermal properties and shrinkage ratio of impact polypropylene copolymer 2500H. Results showed that the nucleating agent HPN-B had a greater influence on the performance of the 2500H, the additive amount of 0.08%, the flexural modulus and tensile strength increased by 22% and 5.4% respectively. The HPN-B improved rigidity of the sample, and the Charpy notched impact strength increased slightly. The crystallinity and heat deformation temperature were increased by the HPN-B, shrinkage ratio of transverse and machine direction decreased 6.15% and 8.20% respectively in the performance of heat processing. |
