Description
技术领域
本发明涉及一种阻燃的聚氨酯防水卷材及其制备方法。
背景技术
聚氨酯主要是具有热塑性的线性结构，它比PVC发泡材料有更好的稳定性、耐化学性、回弹性和力学性能，具有更小的压缩变型性。隔热、隔音、抗震、防毒性能良好。因此用作包装、隔音、过滤材料。
聚氨酯卷材是目前应用广泛的材料，主要由玻璃纤维布和具有防水和阻燃性能聚氨酯胶层复合而成，聚氨酯卷材的防水和阻燃性能是重要的性能指标，本领域的技术人员希望聚氨酯卷材的防水和阻燃性能可以做得更好。
发明内容
本发明要解决的技术问题是提供一种具有出色的阻燃防水性能的阻燃的聚氨酯防水卷材及其制备方法。
为解决上述问题，本发明采用如下技术方案：
一种阻燃的聚氨酯防水卷材，包括陶瓷纤维布,所述陶瓷纤维布的背面设置有阻燃聚氨酯层,所述陶瓷纤维布的正面设置有防水聚氨酯层,所述防水聚氨酯层和阻燃聚氨酯层均与陶瓷纤维布粘合,所述陶瓷纤维布的正面和背面分别设置有第一连接丝和第二连接丝,所述第一连接丝和第二连接丝均呈弧形设置,所述第一连接丝和第二连接丝均与陶瓷纤维布为一体式设置,所述第一连接丝与防水聚氨酯层浇筑成一体,所述第二连接丝与阻燃聚氨酯层浇筑成一体；
所述阻燃聚氨酯层由按重量份数配比的聚醚型热塑性聚氨酯104-110份、双酚F二缩水甘油醚3-9份、γ-氨丙基三乙氧基硅烷3-7份、三异丙苯基磷酸酯4-8份、氟基烷基聚醚改性聚硅氧烷36-40份、异佛尔酮二异氰酸酯10-12份、四针状氧化锌晶须9-13份、氢氧化镁7-10份和2-羟基-4-正辛氧基二苯甲酮4-7份组成；
所述防水聚氨酯层由按重量份数配比的蓖麻油改性酚醛树脂65-88份、丁腈橡胶22-24份、氯化亚锡3-7份、钛酸四异丙酯2-4份、二苯基甲烷二异氰酸酯三聚体28-33份、一缩二丙二醇20-22份、三羟甲基乙烷1-3份、异辛酸锌3-7份、二月桂酸二丁锡2-4份、丙酮60-66份、明矾3-6份和碳酸氢钠7-9份组成。
氯化亚锡与酚醛树脂和丁腈橡胶复配可以起到协同性的作用，促进酚醛树脂对丁腈橡胶的硫化。固化过程中橡胶分子贯穿于酚醛树脂的网络当中，形成典型的互穿网络结构，获得良好的韧性。
明矾和碳酸氢钠复配可以起到协同性的效果，起均匀发孔的作用。
