摘　　要：研究同向双螺杆挤出机的螺杆结构、脱硫温度和螺杆转速对胶粉脱硫的影响。结果表明:螺杆结构越有利于提高螺杆的混合和剪切能力,胶粉的溶胶含量越大,交联密度越小;当脱硫温度从170℃升高至190℃时,胶粉的脱硫效果有一定改善;当螺杆转速从50 r·min^(-1)增至90 r·min^(-1)时,胶粉的脱硫效果明显改善;当脱硫温度为180~190℃、螺杆转速为50~70 r·min^(-1)时,中等混合和剪切能力螺杆脱硫的胶粉的脱硫效果较好,脱硫胶粉胶料的拉伸性能较优。The effect of screw structure,desulfurization temperature and screw speed on the rubber powder desulfurization by the co-rotating twin screw extruder was studied.The results showed that the screw structure was more conducive to improving the mixing and shear ability of the screw,and the larger the sol content of the rubber powder was,the smaller the crosslinking density was.When the desulfurization temperature increased from 170℃to 190℃,the desulfurization effect of the rubber powder was improved to a certain extent.When the screw speed increased from 50 r·min^(-1) to 90 r·min^(-1),the desulfurization effect of the rubber powder was significantly improved.When the desulfurization temperature was 180~190℃and the screw speed was 50~70 r·min^(-1),the desulfurization effect of the rubber powder with medium mixing and shear ability screw were better,and the tensile properties of the desulfurization rubber powder compound were superior.
