摘要

获得了含有不同摩尔比的甲基丙烯酸缩水甘油酯（GMA）、甲基丙烯酸甲酯（MMA）和丙烯酸正丁酯（BA）的聚丙烯酸树脂。六氟磷酸三芳基锍被用作光引发剂，并与 GMA 的环氧基团发生反应。研究了聚丙烯酸树脂的化学结构和紫外线固化反应参数与粉末涂料功能特性之间的关系。根据厚度、光泽度、粗糙度、变形性、抗划伤性、对钢的附着力、硬度和水接触角确定了涂层的外观和机械性能。DMA 用于评估交联密度。结果表明，粉末涂料具有良好的物理和机械性能，固化时间为 70 秒。

UV-curable powder transparent coatings based on oligo(meth)acrylic resins

Polyacrylic resins containing glycidyl methacrylate (GMA), methyl methacrylate (MMA) and n-butyl acrylate (BA) in various molar ratios were obtained. Triaryl sulfonium hexafluorophosphate was used as a photoinitiator and reacted with the epoxy groups of GMA. The relationship between the chemical structure of polyacrylic resins and the parameters of the UV curing reaction and the functional properties of powder coatings was investigated. The appearance and mechanical properties of the coatings were determined based on thickness, gloss, roughness, deformability, scratch resistance, adhesion to steel, hardness, and water contact angle. DMA was used to assess the cross-link density. Powder coatings with good physical and mechanical properties and curing time of 70 s were obtained.
