▎ 摘　　要

NOVELTY - An elastomer-modified asphalt coiled material comprises a modified asphalt layer comprising matrix asphalt, graphene oxide, bismuth nitrate, N-methylmorpholine-N-oxide, MA-100 carbon black, urea, and palm wax emulsion. USE - Elastomer modified asphalt coiled material used in construction. ADVANTAGE - The elastomer modified asphalt coiled material is environmentally friendly, and has excellent acid resistance, alkali resistance, waterproof property, wear resistance, folding resistance, adhesiveness with respect to various metal, concrete, and plastic surfaces, can be folded at multiple angles, and reduced number of splice, and provides economical construction having excellent efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of elastomer modified asphalt coiled material, which involves mixing matrix asphalt, styrene butadiene copolymer, styrene butadiene rubber, coumarone resin, tackifier, silicone rubber, magnesia, melamine phosphate, diethanolamine, barium sulfate, plasticizer, kaolin powder, activated carbon, polyurethane, polyether polyol, butyl stearate, anti-aging agent, lightweight silicon powder, graphene oxide, bismuth nitrate, MA-100 carbon black, urea, adding 95% ethanol of 4-5% raw material in a mixer, using pressure and stirring of internal mixer, breaking the hard components to form soft components, mixing the components at 164 degrees C at 0.12 MPa, after mixing for 50 minutes, adding palm wax emulsion, and N-methylmorpholine-N-oxide to the obtained mixture in mixer, stirring for 12 minutes, ultrasonically treating for 43 minutes, adding thickener and activated carbon to disperse fully, evenly dispersing by cutting uniformly, cooling to 112 degrees C, and flowing the prepared oil-immersed material into the oil-immersed tank.
