Abstract Since a production line for 3D printing is easier to change a product model than that for traditional manufacturing one, 3D printing technology is developing and growing faster than most other technologies. A thermoplastic polyurethane is suitable for a 3D printing material because of easy control of its properties by changing a hard/soft segment ratio. A polyurethane having a low content of hard segment can be melted at low temperature and shows high rebound resilience and high slip resistance. However, it is not suitable for a shoe outsole material because of its low abrasion resistance. In this study, hydroxyl-terminated polydimethylsiloxane (PDMS-OH) was used as an additional polyol to improve abrasion resistance. Polyurethanes were synthesized by adding a small amount of PDMS-OH. Abrasion and slip resistances of the synthesized polyurethanes were investigated as a shoe outsole material for 3D printing. The result showed that both properties of PDMS-containing polyurethanes were strongly depended on the content of PDMS.

端羟基聚二甲基硅氧烷与聚醚多元醇合成热塑性聚氨酯及其耐磨性研究

摘要 由于3D打印生产线比传统制造生产线更容易改变产品模型，因此3D打印技术的发展和增长速度比大多数其他技术都要快。热塑性聚氨酯适用于 3D 打印材料，因为它可以通过改变硬/软链段比率轻松控制其性能。硬链段含量低的聚氨酯可以在低温下熔化，并表现出高回弹性和高防滑性。但由于耐磨性低，不适合做鞋外底材料。在这项研究中，羟基封端的聚二甲基硅氧烷 (PDMS-OH) 被用作额外的多元醇以提高耐磨性。聚氨酯是通过加入少量的 PDMS-OH 合成的。研究了合成聚氨酯作为 3D 打印鞋外底材料的耐磨性和防滑性。结果表明，含 PDMS 的聚氨酯的两种性能都强烈依赖于 PDMS 的含量。
