摘要: 用磷酸和钢渣制备改性钢渣,以改性钢渣取代部分炭黑与丁苯橡胶复合,制备改性钢渣代炭黑环保型丁苯橡胶,研究了磷酸/钢渣质量比、改性钢渣/炭黑质量比和促进剂/硫磺质量比对所制样品力学性能的影响. 结果表明,当磷酸/钢渣质量比为10:250时,改性钢渣具有最优的孔结构,比表面积为15.093 m2/g,孔体积为0.0868 mL/g,平均孔径为24.87 nm;当改性钢渣/炭黑质量比为260:250、促进剂/硫磺质量比为10:15时,丁苯橡胶的力学和经济综合性能最佳,拉伸强度为23.7 MPa,邵尔A硬度为67.9,撕裂强度为41.2 kN/m.

Abstract: Phosphoric acid and steel slag were used to prepare modified steel slag, then, environmentally friendly styrene butadiene rubber were prepared by synthesizing styrene butadiene and carbon black partially substituted by modified steel slag. The effects of ratios of phosphoric acid/steel slag, modified steel slag/carbon black and accelerator/sulfur on the mechanical properties of prepared samples were studied, respectively. The results showed that when the mass ratio of phosphoric acid/steel slag was 10:250, modified steel slag showed the optimal pore structure, the specific surface area, pore volume and average pore diameter were 15.093 m2/g, 0.0868 mL/g and 24.87 nm accordingly. With the mass ratios of modified steel slag/carbon black and accelerator/sulfur as 260:250 and 10:15, the prepared sample presents the best comprehensive performance in terms of mechanics and economy, tensile strength 23.7 MPa, Shore A hardness 67.9 and tear strength 41.2 kN/m.
