一种低烟无卤阻燃热塑性聚氨酯弹性体材料及其制备方法

本发明涉及无卤阻燃高分子材料技术领域，尤其涉及一种低烟无卤阻燃热塑性聚氨酯弹性体材料及其制备方法。本发明使用相容剂与阻燃剂表面氨基在界面原位成键，配合两步法工艺实现高效阻燃与抑烟，全部阻燃功能组分的总用量约23%～30%，组分D集成了磷‑氮化学阻燃，其金属离子且可催化成炭及促分散，协同配方中的成炭剂、纳米协效剂、抑烟剂和相容剂形成致密连续的精密炭层；使得材料极限氧指数≥30%、在1.6mm厚度下达到UL 94 V‑0级、最小透光率≥70%；同时避免了因高填充对TPU微相分离结构的破坏并改善了两相界面结合，材料拉伸强度≥20MPa、断裂伸长率≥450%，力学与加工性能得到充分保留。
