Preparation and Property of Waterborne Polyurethane Waterproofing Composites

Abstract:

Waterborne polyurethane waterproofing composite has been prepared using polyurethane emulsion, cement, sand, and distilled water as raw materials, respectively. The compression performance of the samples has been determined by tensile testing machine. The microstructure of the samples has been observed by metallographic microscope. At the same time, the water resisting property of samples has been presented. The result shows that the surface of samples becomes the more smoothing with the increase ratio of cement to sand. The best compressive strength and water resisting property have been obtained when the weight of polyurethane emulsion to distilled water was 1:5 and the ratio of sand to cement was 2.1:1.
