摘 要:本文以双环戊二烯(DCPD)和苯酚为原料,以自制的新型强酸性阳离子交换树脂为烷基化反应的催化剂,催化苯酚与DCPD发生反应生成双环戊二烯苯酚树脂(DPR)。用阳离子交换树脂替代传统含氟催化剂作为烷基化反应的催化剂,减少了含氟废水的产生,更加绿色环保。通过改变反应时间、反应温度、原料配比、催化剂用量以及正交实验,探究烷基化反应的最佳工艺条件以及阳离子交换树脂磺化度对产物的影响,使合成的树脂能够符合电子用树脂的要求。同时探究DPR树脂的结构,并测定DPR树脂中不同聚合度组分的含量,以及DPR树脂的软化点、收率等数据。实验表明,当采用新型强酸性阳离子交换树脂为催化剂,反应条件为3 h、120℃,原料配比为4∶1,催化剂用量为20%时,聚合度为0的组分含量可达92.36%。In this paper,dicyclopentadiene(DCPD)and phenol were used as raw materials,and a new strong acidic cation exchange resin made by ourselves was used as the catalyst for alkylation reaction.The reaction of phenol with DCPD was catalyzed to produce dicyclopentadiene phenol resin(DPR).Using cation exchange resin to replace the traditional fluorine-containing catalyst as the catalyst of alkylation reaction reduces the production of fluorine-containing wastewater and is more green and environmental friendly.By changing the reaction time,reaction temperature,raw material ratio,catalyst dosage and orthogonal experiment,the optimal process conditions of alkylation reaction and the influence of sulfonation degree of cation exchange resin on the product are explored,so that the synthesized resin can meet the requirements of electronic resin.At the same time,the structure of DPR resin was explored,and the contents of components with different degrees of polymerization in DPR resin,as well as the softening point and yield of DPR resin were determined.The experiment shows that when the new strong acidic cation exchange resin is used as the catalyst,the reaction conditions are 3 h,120℃,the ratio of raw materials is 4∶1,and the amount of catalyst is 20%,the content of component with polymerization degree of 0 can reach 92.36%.
