Abstract

Two kinds of double comb-like quaternary ammonium salt polymers P(DPA-EPI) and P(DBA-EPI) with lower polarity were designed and synthesized using epichlorohydrin (EPI), di--propylamine (DPA) and di--butylamine (DBA) as raw materials. The transparent antistatic epoxy resin coatings were obtained using the two polymers as antistatic agents, respectively. Because P(DPA-EPI) and P(DBA-EPI) with good hygroscopic performance are easily dissolved in epoxy resin paints and are nearly linearly arranged in the epoxy resin paints, the obtained transparent antistatic epoxy resin coatings achieve good antistatic properties. The values of of the coatings reach 5.13 × 10 Ω sq and 2.69 × 10 Ω sq, respectively, with a lower addition amount of polymers of only 1.0 wt%. The two antistatic epoxy resin coatings also have good durability. Compared to the epoxy resin coating, with the introduction of P(DPA-EPI) and P(DBA-EPI), the thermal stability and adhesion of the antistatic epoxy resin coatings do not change obviously, but the Rockwell hardness values slightly reduce.

摘要

以环氧氯丙烷（EPI）、二丙胺（DPA）和二丁胺（DBA）为原料，设计合成了两种极性较低的双梳状季铵盐聚合物P（DPA-EPI）和P（DBA-EPI）。分别以这两种聚合物作为抗静电剂，制备了透明抗静电环氧树脂涂料。由于具有良好吸湿性能的P（DPA-EPI）和P（DBA-EPI）易溶于环氧树脂涂料中，且在环氧树脂涂料中近乎线性排列，因此所制备的透明抗静电环氧树脂涂料具有良好的抗静电性能。涂料的表面电阻值分别达到5.13×10Ω·sq和2.69×10Ω·sq，聚合物添加量仅为1.0 wt%时添加量较低。这两种抗静电环氧树脂涂料还具有良好的耐久性。与环氧树脂涂料相比，随着P（DPA-EPI）和P（DBA-EPI）的引入，抗静电环氧树脂涂料的热稳定性和附着力没有明显变化，但洛氏硬度值略有降低。
