摘要(Abstract)：

采用甲基丙烯酸羟乙酯与五氧化二磷制备含磷单体—甲基丙烯酸羟乙酯磷酸酯(PMOE),并用于合成含磷丙烯酸乳液。研究含磷单体含量对乳液聚合过程稳定性及其树脂阻燃性能的影响。采用红外光谱(FTIR)分析含磷丙烯酸乳液的化学组成;通过热重分析(TGA)、极限氧指数(LOI)和UL-94方法测试含磷丙烯酸树脂的热稳定性和阻燃性能,并利用扫描电镜(SEM)观察含磷丙烯酸树脂残炭微观形貌。实验结果表明:当乳液体系中含磷单体的含量低于30%(wt)时,可以制备得到具有高单体转化率、低凝胶率且储存稳定良好的含磷丙烯酸乳液。随着含磷单体的提高,树脂的成碳率增大,LOI值提高,阻燃性能也得到提高。当含磷单体的用量为30%(wt)时,改性树脂的LOI值可以达到29.5%,并能通过UL-94测试的V-0级别,700℃下的成碳率可达54%(wt)。通过对树脂残炭的微观形貌分析,证明磷元素在丙烯酸树脂体系中主要起到凝聚相阻燃作用。
