Abstract

The invention relates to the technical field of waterproof rolls, and concretely relates to an anti-aging waterproof roll with papermaking waste mud as a filler. The waterproof roll comprises, by weight, 100-150 parts of papermaking sludge powder, 80-120 parts of polyvinyl chloride, 30-40 parts of ethylene -propylene-diene-monomer rubber, 20-35 parts of chlorosulfonated polyethylene, 25-45 parts of natural rubber, 5-20 parts of synthetic rubber, 2-10 parts of reinforced fibers, 0-10 parts of a stabilizer, 0-6 parts of an anti-aging agent D, 5-20 parts of a plasticizer and 2-4 parts of a coupling agent. The waterproof roll has the following advantages: the waste mud discharged papermaking is selected as the filler and can completely or partially replace a calcium carbonate filler, so that fibers in the papermaking waste mud are tightly combined to form the waterproof roll containing a fiber skeleton, the tensile strength is high, and the product quality is improved; and meanwhile, landfill and incineration of the papermaking waste mud can be reduced, environment treatment is facilitated, and obvious social benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material, in particular to an anti-aging waterproof coiled material using papermaking waste mud as a filler. Background technique [0002] At present, the domestic research and development of waterproof membranes mainly include asphalt-based waterproof membranes and polymer waterproof membranes; the main varieties of polymer waterproof membranes are EPDM waterproof membranes, PVC waterproof membranes , chlorinated polyethylene waterproofing membrane, chlorosulfonated polyethylene waterproofing membrane, chlorinated polyethylene rubber blended waterproofing membrane, etc. The raw materials of EPDM waterproofing membrane rely on imports, and the production process requires a vulcanization process, so High cost; chlorinated polyethylene or polyvinyl chloride waterproof membrane has low strength. [0003] China's invention patent application 99112580.0 pointed out that the poor elasticity o...
