Abstract

A self-adhering rubber water-proof coiled material and a method for preparing the same composed of a rubber water-proof coiled material basal layer, a glue spreading reinforcement layer and a self-adhering rubber waterproof layer on the glue spreading reinforcement layer. The glue spreading reinforcement layer is glue spreaded nonwoven cloth or glue spreaded glass-fiber cloth. The self-adhering rubber waterproof layer is produced by mixing the following materials in proportion by weight: 60-70 portions of ethylene propylene terpolymer (PET); 10-26 portions of butyl rubber; 4-25 portions of chloroprene rubber; 50-70 portions of black carbon; 50-70 portions of fine particle calcium carbonate; 2-7 portions of coumarone; 10-20 portions of naphthenic oil; 5-10 portions of zinc oxide and 0.7-1.2 portions of stearic acid. The construction art is simple and fast. Because the self-adhering base material contains hydrophilic material, the basal layer can be in wet lay up if the basal layer has no water. The method has no glue brushing and glue shining process so as to save time limit for a project and the cost, effectively avoid hollow casing and burst phenomenon and form a whole a complete waterproof sealing system.

Description

technical field [0001] The invention relates to a rubber waterproof coiled material used in building construction and a preparation method of the waterproof coiled material. Background technique [0002] Waterproof membrane is a commonly used building material in building construction. In underground engineering and water conservancy engineering construction, waterproof membrane is of great significance to reduce leakage and withstand high water pressure. The existing EPDM waterproof membrane has excellent properties such as high strength, high elongation, high tear strength, high and low temperature resistance, ozone resistance, and aging resistance, so it is widely used in building construction. However, after the existing EPDM waterproofing membrane is laid, the waterproof base material cannot be closely combined with the building base, and water leakage is easy to occur. In case of local water seepage in the waterproof layer, it will also cause "water channeling" under ...
