NOVELTY - A high friction coefficient styrene-butadiene rubber comprises 100 parts mass styrene-butadiene rubber, 30-50 parts mass quick-extruded carbon black, 30-50 parts mass light calcium carbonate, 10-30 parts mass paraffin oil, 4-6 parts mass zinc oxide, 1 part mass stearic acid, 6-12 parts mass butene derivative, 3-6 parts mass graphene, 1-2 parts mass N-cyclohexyl-2-benzothiazolesulfenamide, 0.5-1 part mass tetramethylthiuram disulfide, 1-2 parts mass 4,4'-dithiodimorpholine and 1-2 parts mass sulfur. The butene derivative is low-molecular-weight butene oligomer with molecular weight of 3000 or less. The graphene has particle size (D50) between 5 μm and 50 μm. USE - The high friction coefficient styrene-butadiene rubber is useful for ceramic tile. ADVANTAGE - The styrene-butadiene rubber has friction coefficient of more than 3 on the surface of wet and slippery ceramic tiles, and friction coefficient of more than 18 on the surface of dry ceramic tiles, and excellent anti-skid performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the high friction coefficient styrene-butadiene rubber, which involves (1) mixing graphene with paraffin oil whose weight is 3-5 times the weight of graphene, grinding 3 times, and mixing using a three-roll mill, where the grinding scale is 0.1 grid, (2) weighing all raw materials, calculating the weight of paraffin oil mixed with graphene after weighing graphene, and deducting when weighing paraffin oil, (3) adding styrene-butadiene rubber to a kneader, kneading, adding to a mixture of quick-extruded carbon black, light calcium carbonate, paraffin oil, zinc oxide, stearic acid, butene derivative and graphene, mixing, kneading, continuously pressurizing and mixing after lifting bolt, and discharging glue, and (4) placing the above-mentioned mixed rubber materials at room temperature, adding to kneader for kneading, then adding N-cyclohexyl-2-benzothiazolesulfenamide, tetramethylthiuram disulfide, 4,4'-dithiodimorpholine and sulfur, continuously kneading, and discharging glue.
