摘要
对非端氨基聚醚的聚脲喷涂弹性体配方进行了研究,考察了聚丙二醇(PPG)软段、硬段含量以及扩链剂对弹性体性能的影响,制备出适用于混凝土桥梁和水处理池的防水防渗层材料,也可用于机械设备内衬。
The recipes of polyurea spray elastomer based on non-terminated amine polyether were studied. The influence of contents of PPG soft segment and rigid segment, chain extender, etc. on performance of the elastomer is investigated. The water-proof and permeating-proof polyurethane materials suitable for concrete bridge and water treatment pool as well as interior lines of mechanical equipment were prepared.
