Description

一种含氮杂环芳香聚醚多元醇及其制备方法和聚氨酯硬质 泡沫
技术领域
本发明属于聚氨酯硬泡材料领域,具体涉及一种含氮杂环芳香聚醚多元醇及其在聚氨酯硬泡中的应用。
背景技术
硬质聚氨酯泡沫作为一种高分子绝热保温材料,由于具有高强度、隔热保温等优良特性,在保温隔热领域有广泛的应用。但是随着全球资源越来越紧缺,社会对资源节约型产品的要求越来越高,尤其是近年来碳达峰和碳中和的政策加持,建设零碳园区和零碳社区成为未来的一个发展方向。因此高强度和较好的导热聚氨酯泡沫是目前研究的重要方向之一。
CN106590379A公开以含溴二元醇/酚为起始剂,在催化剂作用下与环氧氯丙烷进行开环聚合反应,得到双官能度的聚环氧氯丙烷,再将上述产物与强碱溶液反应得到端环氧基化合物,最后该端环氧基化合物进行水解反应后再经后处理得到含卤阻燃聚醚多元醇。该工艺优点是原料价廉易得,反应简单;但是该方法制备的聚醚多元醇较苯胺聚醚活性低,所制得的泡沫强度和导热也未得到较好提升。
CN104877105 A公开了一种聚氨酯硬泡组合料及其制备方法,该方法使用HFC-365mfc/227ea作为发泡剂,成本较高,且不环保。
CN101257947 A公开了一种用于甲酸发泡的聚异氰脲酸酯硬质泡沫的催化剂体系以及生产该聚异氰脲酸酯硬质泡沫的方法和可由这种方法得到的聚异氰酸酯硬质泡沫。该方法制得的组合料无法应用于管道喷涂体系,且含有物理发泡剂戊烷,易燃易爆。
因而,鉴于以上问题,希望合成一种简单高效的反应型多元醇,可以解决上述组合料不环保、不安全的问题,并提高聚氨酯泡沫的强度和降低导热。
