季铵盐改性丙烯酸酯抗静电剂合成及UV固化性能

本文采用甲基丙烯酸β羟乙酯(HEMA)、异佛尔酮二异氰酸酯(IPDI)及自制的N,N,N三乙基2羟乙基氯化铵合成了一种季铵盐改性丙烯酸酯抗静电剂。使用核磁共振谱表征产物结构。将产物制成浓度40%的甲基丙烯酸β羟乙酯(HEMA)溶液,通过UV固化成膜,涂膜的表面电阻为106Ω,水洗后表面电阻为107Ω。为了得到综合性能优异的涂膜,添加活性稀释剂1,6己二醇二丙烯酸酯(HDDA)与低聚物(PUA),研究了各组分对固化时间、硬度、附着力以及抗静电性的影响。最佳配比(质量分数):季铵盐改性丙烯酸酯抗静电剂40%,HEMA40%,HDDA15%,PUA5%。涂膜的性能:外观(目测)澄清透明,固化时间3s,硬度2H,附着力1级,表面电阻108Ω。

Synthesis and Properties of Quaternary Ammonium salt Modified UV-curable Acrylate Antistatic Agent

This paper The preparation of quaternary ammonium salt modified acrylate antistatic agent from reaction of 2-hydroxyethylmehtacrylate(HEMA),aliphatic isosporone(IPDI)and self-made N,N,N-triethyl-2-hydroxyethanaminium were described.The structure of the product was characterized with NMR . The product was used to prepare 40% concentration of 2-hydroxyethylmethacrylate (HEMA) solution. The surface of the resistance of UV-curing film was up to 106Ω. It can keep 107Ω even after washing with water. In order to obtain better performance film,1,6-hexanediol diacrylate (HDDA) and oligomer (PUA) were added. The influence of each component on the curing time,hardness,adhesion and anti-static were studied. The optimum proportion (mass fraction) is quaternary ammonium salt modified acrylate antistatic agent 40%,HEMA 40%,HDDA 15%,and PUA 5%. The performance of film: Appearance (visual) transparent,Curing time 3s,Hardness 2H,Adhesion 1-level,Surface of the resistance 108Ω.
