摘要
环氧化大豆油丙烯酸酯(AESO)已大规模用于UV固化涂料中,但目前同时获得高生物基含量以及优异机械性能的大豆油基光固化涂料依然是一个很大的挑战。文中设计并合成了异山梨醇甲基丙烯酸酯(ISDMA)作为光固化活性稀释剂。使用流变仪研究了ISDMA对AESO稀释性的影响。将ISDMA与AESO混合制备了一系列生物基UV固化涂料,并对这些涂料的热机械性能、力学性能和涂层基本性能进行了评估。结果表明:ISDMA对AESO表现出良好稀释性的同时,可以有效地提高固化涂层的玻璃化转变温度(Tg)、储能模量和硬度。
The epoxy soybean oil acrylate （AESO） has been widely used in UV-curable coatings, but it is still a great challenge to obtain soybean oil-based photocurable coatings simuhaneously having high bio-based content and excellent mechanical properties. In this paper, an isosorbide dimethacrylate （ISDMA） was designed and synthesized as a photocurable reactive diluent. The solubility of reactive diluents for AESO was studied using rheometer. A series of UV-curable coatings were prepared by mixing reactive diluents with AESO, and systematically evaluated their thermo-mechanical, mechanical and basic coating properties. The results showed that ISDMA exhibited good dilution capabilities for AESO, and can effectively increase the glass transition temperature （ Tg）, storage modulus and hardness of the cured material.
