摘要

在本研究中，使用通用注塑机制备了聚丙烯基泡沫复合材料。将化学发泡剂以1重量%和2重量%的比例添加到纯聚丙烯（PP）聚合物、滑石填充聚丙烯（PP-T）复合材料和滑石填充聚丙烯/乙烯-丙烯-二烯共混物（PP-T-EPDM）复合材料中。研究了发泡剂含量对纯聚丙烯聚合物和聚丙烯复合材料力学性能和泡沫性能的影响。结果表明，随着化学发泡剂含量的增加，发泡剂的拉伸强度、拉伸模量、冲击强度、硬度、泡孔直径、泡沫密度和粘度值以及表层厚度均降低，而体积膨胀率增加。

A study of the cell morphology and mechanical properties of bumper material PP-T-EPDM composite foam

In this study, cellular polypropylene based composite foams were prepared using an universal injection moulding machine. The chemical foaming agent was added to neat polypropylene (PP) polymer, talc filled polypropylene (PP-T) composite and talc filled polypropylene/ethylene-propylene-diene blend (PP-T-EPDM) composite materials at the ratio of 1% and 2% by weight. The influence of foaming agent content on the mechanical and cellular properties of both neat PP polymer and PP composites was investigated. The results showed that the tensile strength, tensile modulus, impact strength, hardness, cell diameter, foam density and viscosity values and skin layer thickness decreased while volume expansion ratio increased with the increment in chemical blowing agent content.

期刊介绍： Cellular Polymers is concerned primarily with the science of foamed materials, the technology and state of the art for processing and fabricating, the engineering techniques and principles of the machines used to produce them economically, and their applications in varied and wide ranging uses where they are making an increasingly valuable contribution. Potential problems for the industry are also covered, including fire performance of materials, CFC-replacement technology, recycling and environmental legislation. Reviews of technical and commercial advances in the manufacturing and application technologies are also included. Cellular Polymers covers these and other related topics and also pays particular attention to the ways in which the science and technology of cellular polymers is being developed throughout the world.
