环氧树脂的配合对氯磺化聚乙烯CSM橡胶性能的影响 （王敏 徐州工业职业技术学院 江苏徐州 221140） 摘要 本次实验主要研究不同的环氧树脂的配合对氯磺化聚乙烯CSM橡胶性能的影响，主要采用对比实验法、正交实验法，在实验中先是炼母炼胶，辊筒温度控制在60℃，将辊距调至0mm时加料(其加料顺序为：氯磺化聚乙烯CSM→芳烃油DOP+炭黑N770将通过辊距调至为0.5mm，下片时辊距为2mm。在第一轮混炼中将辊距调至2mm时加入母炼胶等配合剂，（其加料顺序为：母炼胶→硫化促进剂TRA/硫化促进剂TT/氢化松香/硬脂酸SA/松香→环氧树脂），下片时辊距为3.85mm。在第一轮混炼中，将辊距调至2mm加入母炼胶等配合剂(其加料顺序为：母炼胶→硫化促进剂TRA/MgO/氢化松香/环氧树脂E—44)下片时辊距调至3.85mm，其硫化温度均为155℃，硫化压力为15 Mpa,为防止胶料产生气泡，提高胶料的致密性；使胶料流动，充满模具，改善硫化胶的物理性能。硫化时间由硫化仪测定的正硫化时间而定。结果表明：CSM配方中常用的TRA是CSM最有效的硫化促进剂，当加入MgO时不仅可起到了酸吸收的作用，同时使性能有所提高。从拉伸强度、伸长率、300%的定伸应力、撕裂强度及压缩永久变形来看硫化促进剂TRA优于TT，同样氢化松香与松香比，选用氢化松香较好。 关键词：环氧树脂E—44、氯磺化聚乙烯CSM、硫化促进剂TRA、TT Epoxy resin with the chlorosulfonated polyethylene CSM properties of rubber (Min Industrial Vocational and Technical College in Xuzhou, Jiangsu Xuzhou 221140) Abstract The main experiment on different epoxy resin with the chlorosulfonated polyethylene CSM properties of rubber, mainly in a comparative experiment, orthogonal experiment, in the experiment first home Lian Lian Jiao, roller temperature control in 60 ℃, will be transferred to roll away from 0 mm when feeding (their feeding chronological order: chlorosulfonated polyethylene CSM → aromatic oil DOP + carbon black N770 will be transferred to roll away from the 0.5 mm, from the roll of films for the 2 mm. Mixing in the first round will be raised to 2 mm from the roll when joined with the mother Lianjiao, and other agents, (their feeding chronological order: Mother Lianjiao → vulcanization accelerator TRA / vulcanization accelerator TT / hydride -/ Stearate SA / Rosin → epoxy resin), the films roll from the 3.85 mm. In the first round of mixing, from the roll will be raised to 2 mm joined with the mother of Lianjiao, such as (their feeding chronological order: Mother Lianjiao → vulcanization accelerator TRA / MgO / hydride Rosin / epoxy E-44) under Films from the roll raised to 3.85 mm, its curing temperature are 155 ℃, curing pressure for 15 Mpa, in order to prevent a bubble compound, raising the dense com
