Abstract:Performance of waterproof materials will seriously restrict the reliability of waterproofing engineering,especially in complex underground environment. Therefore,this paper studied the performance changing of spraying quick-setting rubber under extreme chemical conditions in detail. The results show that the spraying fast-setting rubber modified emulsified asphalt have excellent chemical resistance ability,its tensile properties,elongation at break and bond strength retention rate are all higher than 90%,after being soaked continuously for 168 hours in extreme chemical conditions. With excellent chemical resistance and water impermeability, it can be applied to a variety of groundwater environments.
Key words:fast-setting rubber,asphalt waterproof coating,chemical resistance
