摘要
讨论了在室温下制备端羟基聚丁二烯 (羟丁 )型 PU防水涂料中的半预聚程度、NCO%以及固化剂、焦油填充量等对力学性能的影响 ,用红外光谱法确定了固化时间 。
The (HTPB PU) waterproof coating cured at indoor temp erature is influenced by the degree of prepolymerization,NCO%,extenders and the proportion of coal tar.The cured time can be researched by IR.It is shown that t he new system is better than anti hydrolysis,anti corrosiveness and oil resis tance.
