Abstract In this work, a novel phosphorous containing UV-curable monomer (PA) was synthesized by the reaction of phytic acid and glycidyl methacrylate. The structure of PA was confirmed by 13C NMR, 1H NMR, 31P NMR and FTIR. Pyrolysis gas phase products of PA cured coating mainly include CO, CO2, H2O, alkyl-containing compounds, carbonyl-containing compounds and aromatic compounds. Cooperated with other two kind of reactive monomers, TAEP and TGICA, PA showed excellent fire protection effect for PMMA matrix, extending fireproof time of PMMA for more than twenty minutes. The SEM results of the carbon residues show that a certain coating prepared can form a uniform and complete expanded carbon layer, resulting in protecting the PMMA matrix from being ignited.

用于UV固化涂料的植酸基单体的合成以提高PMMA的防火安全性

摘要 在这项工作中，通过植酸和甲基丙烯酸缩水甘油酯反应合成了一种新型的含磷紫外光固化单体（PA）。PA的结构经13C NMR、1H NMR、31P NMR和FTIR确证。PA固化涂料的热解气相产物主要有CO、CO2、H2O、含烷基化合物、含羰基化合物和芳香族化合物。PA与其他两种活性单体TAEP和TGICA配合，对PMMA基体表现出优异的防火效果，将PMMA的防火时间延长了20分钟以上。残炭的SEM结果表明，制备的某种涂层可以形成均匀完整的膨胀碳层，从而保护PMMA基体不被点燃。
