非热敏催化剂型喷涂聚氨酯硬泡研究

Study on Spray Rigid Polyurethane Foam Prepared by Non-thermal Catalyst

针对低温环境下聚氨酯硬泡室外喷涂施工存在限制的问题,本研究制备了一种非热敏催化剂,不同温度下的试验表明该催化剂对温度不敏感;室外施工试验证明采用该催化剂的聚氨酯硬泡配方可在11℃下施工,泡沫的性能满足GB 50404—2007《硬质聚氨酯保温防水工程技术规范》的要求。

A new type of non-thermal catalyst is prepared in order to solve the issue on the spraying of rigid polyurethane foam at low temperatures. Experiments at different temperatures indicate the catalyst is temperature-insensitive. Trial construction in the open air shows rigid polyurethane foam prepared by the catalyst can applied at 11℃ and the foam meets the requirements of GB 50404--2007 （Technical code for rigid polyurethane foam insulation and waterproof engineering》.
