摘　　要：通过醇与异氰酸反应合成预聚体及预聚体固化而制备胶辊的研究,结合生产施工过程中的经验及使用胶辊单位的反馈,得出:以聚四氢呋喃二元醇(Mn1000)与ε-己内酯在140℃～160℃合成的聚醚酯二元醇(Mn2000)。该醇与TDI100在90℃合成含-NCO质量百分数为2.4%～3.2%的预聚体,该预聚体再以适量的988SG混和,与复合固化剂(质量比MoCA∶TMP=5∶1)按扩链系数0.85固化,可制得硬度60A以下性能优越的胶辊。The paper discusses that precursor is synthesized by alcohol and isocyanic acid,and it is solidified to prepare rubber roll. According to the experiment of process and the suggestions from the users,the conclusion can be made as follow:politeramethylene(Mn l000) can be combined with ε-caprolactone to get ploy(ester-esther)diol combined with TDI100 to obtain a precursor with 2.4% to 3.2% -NCO, which would be mixed with proper 988SG and solidified with complex curing agent lits quality proportion of MoCA:TMP=5:1)at the 0.85 chain expasion coefficient to obtain the rubber roll which enjoys the good performance and less 60A hardness.
