The invention provides a foldable ethylene propylene diene rubber/POE (polyolefin elastomer) waterproof coiled material, which is characterized by being prepared from the following raw materials in parts by weight: ethylene propylene diene rubber, hydrogenated rosin resin, POE, 1,3-bi(tertiary butyl peroxide diisopropyl) benzene, triallyl isocyanurate, stearic acid, 2-mercapto benzimidazole, lanthanum oxide, chlorinated paraffin, ammonium bicarbonate, zinc oxide, sodium metasilicate, 2-amino-2-methyl-1-propyl alcohol, epoxidized soybean oil, sodium selenite, polyethylene terephathalate, azodicarbonamide, aluminium oxide, hexamethyl disilazane, ethyl ester, diethyl tertiary butanol, trihydrolxy triethylamine 2,2'-disulfbenzothiazole and deionized water. The waterproof coiled material can be folded at any angles, so that the number of splicing parts can be greatly reduced; the water seeping probability can be effectively reduced; meanwhile, the heat insulation and energy saving effects can be achieved; the construction is simple and convenient.
