The invention relates to a rubber composite waterproofing membrane and a producing method, which is compositely composed of a base course and a surface course in staggered superposition, the base course is a rubber waterproof layer, the surface course is chemical fiber non-woven fabric or chemical fiber woven fabric, the main materials of the rubber of the base course are ethylene propylene diene monomer rubber, calculated according to parts by weight, 100 parts of ethylene propylene diene monomer rubber are regarded as the reference, the content of other components is as follows: 5 to 10 parts of zinc oxide, 1 to 3 parts of stearic acid, 0.5 to 3 parts of polyethylene glycol, 1 to 4 parts of paraffin, 40 to 80 parts of fast extruding carbon black, 10 to 50 parts of calcium carbonate, 40 to 80 parts of plasticizer, 0.5 to 1.5 parts of accelerator BZ, 0.5 to 3 parts of accelerator CZ, 0.5 to 1.5 parts of accelerator TMTD and 1 to 3 parts of sulfur. The membrane provided by the invention has the advantages of the good performance, the good aging resistance, the long life span, protecting environment, no pollution, the simple processes and the high producing efficiency.
