摘要 研究了侧链含有氯甲基的高活性氯代聚醚多元醇(CHIROL)与亚膦酸二甲酯钠盐反应,合成高活性含磷阻燃聚醚多元醇(HIROL)的方法。考察了微波技术、反应物料比、催化剂以及溶剂等主要条件对亲核取代反应和产物收率的影响。分析结果表明,当HIROL的磷质量分数达到1 41%~6 73%时,HIROL为透明的琥珀色液体,粘度0 359Pa·s~0 668Pa·s,由其制成的阻燃PU软泡氧指数已达22 6~28 3,其它力学性能和技术指标也符合GB12080-89的要求。

Abstract: The flame retardant polyether polyol(HIROL) containing phosphorus was synthesized with dimethyl phosphite and high reactive chloride polyether polyol(CHIRO) which had chloromethyl group in side chain. The effect of process conditions, such as microwave, reactant ratio, catalyst and solvent etc, on the nucleophilic substitution and yield of product were investigated. The results showed that when the content of phosphorus reached 141%—673%, HIROL was a transparent amber liquid whose viscosity was 0359—0668 Pa·s. Then oxygen index of flame retardant soft PU foam composed of HIROL was 226—283 and the other mechanical and technical parameters were in accord with those in GB12080-89.
