摘要
以多羟甲基苯酚钠和丙烯酰氯为原料,合成了适用于水性UV固化涂料的多羟甲基苯酚丙烯酸酯,通过红外光谱表征了产物的化学结构。探讨了物料比、反应温度、反应时间和催化剂用量等因素对产物产率的影响,结果表明:当n(多羟甲基苯酚钠)∶n(丙烯酰氯)=1∶2、反应温度为0～-5℃、反应时间为2.5h、催化剂四丁基溴化铵用量为0.04%(占物料质量比)时,最有利于产物的合成;多羟甲基苯酚丙烯酸酯的水溶性及涂膜性能,也能较好地满足水性UV固化涂料的应用。
Multi-hydroxymethyl-phenol acrylate which is suitable for waterborne UV curing coating was synthesized by using multi-hydroxymethyl phenol sodium and acryloyl chloride as raw material.Chemical structure of the product was characterized by FT-IR.The relation between the production yield and material ratio,reaction temperature,reaction time and catalyst content was discussed.The results showed that the most favorable reaction condition is when n（multihydroxymethyl phenol sodium）∶n（acryloyl chloride）=1∶2,reaction temperature at 0^-5℃,reaction time 2.5 h,the content of tetrabutyl ammonium bromide 0.04%（accounting for materials quality ratio）;water-soluble and film properties of the multi-hydroxymethyl-phenol acrylate can satisfy the application of waterborne UV curing coating.
