喷涂聚脲施工技术应用研究

The Technology of Spraying Polyurea in Construction

聚脲防水技术是近年来,国外为适应环保需求而研制、开发的一种新型无溶剂、无污染的绿色施工技术,是结构防水技术的最新发展,以环保、耐各种化学腐蚀、高强、耐磨、柔韧性、热稳定性能好、与混凝土附着力强等优越性能在国际上受到推崇和使用。介绍聚脲防水技术的性能特点,研究聚脲防水涂料在京沪高速铁路徐沪段桥面防水的应用,以及出现的一些问题和解决方法。

The Polyurea water-proof technology has been developed into a new pollution-free construction technology with no solvent in recent years in foreign countries,so as to meet the needs of environmental protection.The kind of waterproof coating is durable,flexible,able to bear various chemical erosion,and has a good heat stability and strong adhesion to the concrete.This study explores the functions and characteristics of the Polyurea water-proof technology,the application of this technology to bridges on the Xuzhou-Shanghai section of the Beijing-to-Shanghai high-speed railway,and some existing problems and the solutions.
