摘　　要：以铁水脱硫渣作为橡胶填料,取代部分炭黑与丁苯橡胶复合制备铁水脱硫渣/丁苯橡胶材料,研究铁水脱硫渣/炭黑比(质量比)、铁水脱硫渣粒度、硫化体系和硫化时间等因素对铁水脱硫渣/丁苯橡胶的力学性能影响.结果表明:当铁水脱硫渣/炭黑比为20/30,铁水脱硫渣粒度为16μm(1 000目),硫化体系为促进剂N-叔丁基-2-苯并噻唑次磺酰胺(NS)与硫磺(NS/硫磺质量比为1.00/1.75),硫化时间约为1 500s时,铁水脱硫渣/丁苯橡胶的力学性能与经济效益最好.Molten iron desulphurization slag/styrene butadiene rubber composites were prepared using molten iron desulphurization slag as rubber filler to replace part of carbon black.The effects of molten iron desulphurization slag/carbon black ratio（by mass）,particle size of molten iron desulphurization slag,curing system and curing time on the mechanical properties of the molten iron desulphurization slag/styrene butadiene rubber were studied.The results show that the mechanical performance and economic benefits of the molten iron desulphurization slag/styrene butadiene rubber are the optimal when the molten iron desulphurization slag/carbon black ratio is 20/30,the particle size of the molten iron desulphurization slag is16μm（1 000 mesh）,the curing system is the promoter N-tert-butyl-2-benzothiazole sulfenamide and the sulfur（ratio of the promoter NS and the sulfur is 1.00/1.75）,and curing time is about 1 500 s.
