▎ 摘  要

NOVELTY - Water-swelling-enhanced type modified asphalt waterproof coiled material comprises 150-170 pts. wt. asphalt, 30-35 pts. wt. softening oil, 4-5 pts. wt. styrene butadiene styrene (SBS), 15-20 pts. wt. water-swellable rubber, 10-20 pts. wt. rubber powder, and 20-300 pts. wt. filler. USE - Water swelling enhanced type modified asphalt and waterproof coiled material. Can be used in the preparation of water-proof coiled materials, e.g. SBS modified asphalt, SBS-coiled material-adhesive polymer modified asphalt. ADVANTAGE - The water swelling enhanced type modified asphalt and waterproof coiled material: utilizes the water-type rubber as modified agent, which can enhance water absorption while modifying the asphalt, so as to expand to achieve the effect of plugging; and provides waterproof and leakage-proof. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation methodof water-swelling enhanced type modified asphalt waterproof coiled material comprising: (1) adding butyl benzene rubber, coumarone resin, polyethylene glycol, water-absorbing resin in the double-roller open mill, plasticating at 160℃, then orderly adding nano zinc oxide, stearic acid, graphene oxide, plasticating for 5 minutes at 170℃, then adding sulfur, DM and promoting agent DM at 140℃, plasticating for 10 minutes, finally adding carbon black and white carbon black for reinforcing, cooling for further use, recording as material A, (2) adding asphalt in the reaction kettle, then adding softening agent, raising the temperature to 150℃, adding material A, stirring and dispersing for 40-60 minutes, then raising the temperature to 185℃, adding SBS, stirring for 1-2 hours, after completely dissolving, adding rubber powder to fully swell, at last, adding filler, stirring uniformly and then processing; and ((3) uniformly spraying the B material on the coiled material surface by the glue spraying device, and covering with the isolating film to obtain the product.
