At present, the EPDM waterproof membranes sold in the market are basically produced according to the national polymer waterproof membrane standards. When used on buildings, they have good waterproof effects and long working life. The fly in the ointment is that : Both the EPDM waterproof membrane and the waterproof layer used to generate it are easy to burn when exposed to open flames, so there are certain safety hazards, especially not suitable for waterproof and anti-corrosion projects for buildings with high fire protection requirements Therefore, it is not ideal from the perspective of practicality and economy

Abstract
The invention discloses an ageing-resistant ethylene-propylene-diene monomer rubber (EPDM) / POE waterproof roll which is characterized by being prepared from the following raw materials in parts by weight: EPDM, butadiene styrene rubber, POE, 1,3-di(tert-butylperoxyisopropyl)benzene, triallyl isocyanurate, stearic acid, 2-mercapto benzimidazole, lanthanum oxide, di-2-ethylhexylsulfosuccinate, absolute ethyl alcohol, polyvinyl alcohol, zinc oxide, argil, nano-silica, vinyltris(beta-methoxyethoxy)silane, ethylene bis stearamide, sodium phosphate, 2,2'-dithio-dibenzo thiazole and deionized water. According to the waterproof roll disclosed by the invention, EPDM serves as a matrix, and a proper amount of POE and butadiene styrene rubber are added, so that the wear resistance of rubber materials is greatly enhanced, and the ageing resistance and oxidization resistance of the waterproof roll disclosed by the invention are improved.
Description
technical field [0001] The invention relates to a building waterproof material, in particular to an anti-aging EPDM / POE waterproof coiled material and a production method thereof. technical background [0002] EPDM membrane is recognized as the waterproof membrane with the best comprehensive performance in the world, and EPDM has been used in a large number of Chinese construction projects because of its excellent physical properties. In recent years, with the advancement of social science and technology and the enhancement of people's awareness of environmental protection, the industry's requirements for building waterproof materials have changed from the previous single waterproof function to the multifunctional direction of long life, flame retardancy, and ozone aging resistance. At present, the EPDM waterproof membranes sold in the market are basically produced according to the national polymer waterproof membrane standards. When used on buildings, they have good waterpr...
