Abstract：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 is 16μm(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.
