Preparation of special non-solidified rubber asphalt waterproof coating
Non-curable rubber asphalt waterproof coating has low high-temperature performance and cannot be applied to facades,sloping roofs,and other locations.Moreover,its viscosity is high at 130℃,and it needs to be heated to above 160℃ before construction can proceed,consuming a large amount of energy and exhaust emissions.In this experiment,the effects of SBS,SBR,rubber powder,asphalt and oil,inorganic fillers,dispersing additives and C5 petroleum resin on the properties of non-curable rubber asphalt waterproof coating were analyzed to develop special non-curable waterproof coating formula.The results show that the softening point of the special non-curable property increases by 35℃,the heat resistance increases by 30℃,the viscosity decreases by 1810 mPa·s at 130℃,and the slip resistance of the sheet material does not slip at 90℃.The special non-curable rubber asphalt waterproof coating has the characteristics of high heat resistance and low viscosity,and can be used for waterproofing of facade or slope roof.The construction can be carried out at 130℃,reducing energy consumption.
