Abstract

The invention discloses tri-ethylene-propylene rubber water proof coiled material that uses tri-ethylene-propylene rubber EP35 or 4045, carbon, fine particle calcium carbonate, ZnO, stearic acid, Rhine wax, anti-aging agent, accelerating agent, vulcanizing agent as raw material. The advantage of the invention is that it is water proof, damp proof, mould proof, pressure proof, acid, alkali, and salt resistant, strong adhesive force, good extension, and strong ageing resistance.

Description

technical field [0001] The invention relates to a waterproof coiled material and a production method thereof, in particular to an EPDM waterproof coiled material and a production method thereof. technical background [0002] At present, the production method of rubber waterproof membrane generally adopts the traditional one-stage vulcanization method of rubber drum vulcanization or pressure tank vulcanization. One-stage vulcanization makes the product press flat, no pattern on the surface, and the specific surface area of ​​the bonding surface is small. Moreover, the material cost of the EPDM waterproof membrane produced by the current process is high, the formula is not well matched, it is easy to bloom, which affects the bonding, and the vulcanization speed is slow during the processing, which affects the vulcanization process time. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, to provide an EPDM...
