Self-adhesive rubber asphalt waterproofing coiled material

The utility model relates to a self-adhesive rubber asphalt waterproofing coiled material, which includes a lower isolation layer adhered on the lower surface of the self-adhesive waterproof layer, an upper isolation layer adhered on the upper surface, and a high strength film adhered in the middle. In use, the lower isolation layer can firstly be stripped, then the coiled material is coated on the base surface, and the upper isolation layer on the corresponding lateral side is stripped when the next coiled material needs to be lapped. Therefore, the time period that the self-adhesive waterproofing layer is exposed at the lap joint position of the coiled material is reduced, the adhering strength is prevented from being reduced due to adhered ash during construction, problems of water permeation/water leakage frequently occurring at the lap joint of the coiled material in prior art is avoided. Thus , the utility model can be widely applied to waterproof processing on base surface of various buildings.
