Preparation of Roofing and Roofing Waterproof Coating for Roof Greening and Exploration of Quick Inspection of Its Resistance

Abstract: According to the advancement of urban construction and the rise of roofing, roof greening has become an important measure to green construction facilities and improve air quality, which has attracted worldwide attention and respected. High-strength polyurethane is expected to be widely used in these areas. In this paper, the preparation of high strength polyurethane waterproof coating was studied. Polyurethane coating was prepared by replacing TDI with MDI in polyurethane prepolymer. At the same time, a method for rapid testing of root-resistant piercing of plant waterproof layer was explored. The strength and resistance of waterproof material Puncture force relationship, through the experimental data obtained polyurethane waterproof membrane tensile strength and its root resistance is proportional to the root. 

Keywords: Polyurethane waterproof coating; Roof greening; Physical puncture; Resistance to plant root piercing; MDI
