摘要/Abstract

摘要： 以松香为原料，先与顺丁烯二酸酐发生Diels-Alder加成反应合成了马来海松酸酐（MPA），接着与己二胺反应合成了马来海松酰胺酸（MPAA），最后与甲基丙烯酸缩水甘油酯反应合成了改性松香甲基丙烯酸酯（MRMA），通过FT-IR和¹H NMR对中间体和目标化合物的化学结构进行了表征，并测试了MRMA的UV光固化膜性能。研究结果表明：MRMA可溶解于常见的丙烯酸酯类活性单体中，UV光固化涂层的玻璃化转变温度（T_g）为124.3℃，最大热失重温度为418.4℃。固化膜硬度为2H，吸水率小于5%，在聚丙烯薄膜上附着力为0级，具有良好的耐水性、耐酸碱性和耐溶剂性能，在UV光固化涂料、油墨及黏合剂中有良好的应用前景。活性稀释剂种类及用量对UV光固化涂层性能影响的分析结果表明：以丙烯酸丁酯（BA）为活性稀释剂时MRMA/BA固化涂层具有良好的综合性能，且随着MRMA用量的增加，涂层的附着力上升，拉伸强度和硬度增加，断裂伸长率先增加后降低，玻璃化转变温度逐渐升高。

Abstract: Maleopimaric anhydride(MPA) was firstly synthesized by Diels-Alder addition reaction of resin acid and maleic anhydride, then the MPA reacted with hexamethylene diamine to prepare maleopimaramide acid(MPAA), finally, modified rosin methacrylate(MRMA) was synthesized via the reaction between maleopimaramide acid and glycidyl methacrylate. The chemical structure of intermediates and goal product were characterized by FT-IR and ¹HNMR. The ultraviolet(UV)-curing properties of MRMA film were investigated. The results showed that MRMA was solvable in usual active acrylic esters. The results of DSC and TG showed that the glass transition temperature(T_g) of the UV-curing coating was 124.3℃ and the peak value in DTG was 418.4℃. The hardness and water-absorption of UV-curing film were 2H and below 5%, respectively. The adhesive force of UV-curing coating on polypropylene film was grade 0. The UV-curing film showed good resistances to acid, alkali, and water. All these indicated that MRMA would have a good prospect of applications for UV-curing coating, printing ink, and adhesive. The effects of the type and dosage of active diluent(AD) on UV-curing coating were also studied. The results showed that UV-curing MRMA coating with butyl acrylate(BA) as AD had good comprehensive performance. The adhesive force, tensile strength, glass transition temperature, and hardness of UV-curing MRMA/BA coating increased with the increase of MRMA content, while the elongation at break increased first and then decreased.
