摘　　要：以4种二胺与环氧氯丙烷发生缩聚反应形成聚胺抗静电剂,并以反应产物的叔胺值与总胺值的比值为判断依据,优选出丁二胺与己二胺为反应物料,并通过四因素四水平正交实验,优化出最佳合成条件,同时对合成的两种聚胺PN-1与PN-2进行抗静电性评价测试。结果表明,二胺与环氧氯丙烷缩聚的最优条件为反应时间6h、反应温度90℃、环氧氯丙烷与二胺摩尔比为5、反应物浓度为50%;PN-1与PN-2在单独使用时,抗静电效果不佳,加量为2mg·L^(-1)时,环己烷的电导率不足30pS·m^(-1);当PN-1、PN-2分别与聚砜以质量比为1∶1复配时,在2mg·L^(-1)的加量下,可使环己烷的初始电导率达到150pS·m^(-1)以上,储存20d后环己烷电导率可达700pS·m^(-1)以上;PN-1、PN-2与聚砜复配的产品对正己烷也有极佳的抗静电效果。Polyamine antistatic agents were formed by condensation reactions between different diamines and epichlorohydrin.Based on the ratio of the tertiary amine value to the total amine value of the reaction products,butylene diamine and hexamethylene diamine were selected as the reaction materials.The optimal synthesis conditions were optimized through four factor and four level orthogonal experiments,and the antistatic properties of the two synthesized polyamines PN-1 and PN-2 were evaluated.The results showed that the optimal conditions for the condensation of diamine and epichlorohydrin were reaction time of 6 hours,reaction temperature of 90℃,molar ratio of epichlorohydrin to diamine of 5,and reactant concentration of 50%;When PN-1 and PN-2 were used alone,the anti-static effect was not good.When the dosage was 2mg·L^(-1),the conductivity of cyclohexane was less than 30pS·m^(-1);When the mass ratio of PN-1 and PN-2 to polysulfone is 1∶1,at a dosage of 2mg·L^(-1),the initial conductivity of cyclohexane can reach 150pS·m^(-1)or above,and after 20 days of storage,the conductivity of cyclohexane can reach 700pS·m^(-1)or above;At the same time,the products of PN-1 and PN-2 compounded with polysulfone also have anti-static effects on n-hexane.
