    Abstract:The influencing factors of tensile properties of polyurethane waterproof coatings are analyzed from three aspects of preparation,maintenance and test. The results show that the forming times,curing environment and stretching rate of waterproof coatings have great influence on the tensile properties of waterproof coatings,and some matters needing attention in the test of tensile properties of waterproof materials are put forward.
