摘要

摘要近年来，汽车行业开始采用替代方法来降低原材料成本和保护环境。重量的增加会导致油耗和二氧化碳排放量上升。本研究旨在通过在一款超小型跨界 SUV 汽车的门板生产中使用发泡聚丙烯来减轻重量，并通过缩短注塑周期来节约能源，从而减少尾气排放。新生产的添加 2% ITP 822 化学发泡剂的门板与现有门板的性能进行了比较。通过泡沫形态结构、冲击力和硬度测试，确定 ITP 822 是一种合适的化学发泡剂。此外，重量减轻了 5.2%。此外，注塑周期时间缩短了约 12%，总周期时间从 35 秒缩短至 31 秒。

Properties of chemically foamed polypropylene materials for application to automobile interior door panels

Abstract In recent years, alternative approaches have been implemented in the automotive sector to reduce raw material costs and protect the environment. An increase in weight causes both fuel consumption and CO2 emissions to rise. This study aims to reduce exhaust emissions due to weight reduction by using foamed polypropylene in the door panel production of a subcompact crossover SUV car and saving energy by shortening the injection cycle time. The newly produced 2 % ITP 822 chemical foaming agent added door panel was compared with the current door panel performances. As a result of foam morphology structure, impact, and hardness tests, it was decided that ITP 822 is a suitable chemical foaming agent. In addition, a weight reduction of 5.2 % was achieved. Moreover, the injection cycle time has been reduced by approximately 12 %, reducing the total cycle time from 35 s to 31 s.
