浇注型聚氨酯弹性体的研制

Preparation of Casting Polyurethane Rubber

采用一步法工艺制备了两种浇注型聚氨酯弹性体体系 ,对胶液的性能及固化后胶层的性能分别进行了测试分析 ,并与预聚法得到的胶层的性能进行了比较 。

s Two systems of casting polyurethane rubber were prepared by one step process,and the properties of the liquid cement and the sub were tested.In addition,comparisons of the properties of subs by one step process and two step process were made.The properties of the system prepared were better than those of the system by two step.
