阻燃润滑剂氰尿酸三聚氰胺盐的一步法合成研究

Study on synthesis of flame retardant lubricant MCA by one-step

以尿素、三聚氰胺为原料合成氰尿酸三聚氰胺盐。考察了分散剂的选取以及原料配比、反应温度、反应时间等因素对目的产物纯度和收率的影响，确定了适宜的反应条件：分散剂A的分散效果最好，用量为三聚氰胺重量的219／6；尿素和三聚氰胺的摩尔比为3：0．85；固化反应温度为280-300℃，时间为60～70min；水解反应温度100-105℃，时间10h。在该条件下，产品纯度为99．6％，收率为94．7％。

Synthesis of melamine cyanurate acid as flame-retardant lubricant was reported with urea and melamine as raw materials, The effects of dispersant, molecular ratio, reaction temperature and reaction time on the reaction purity and yield were studied. The optimum reaction conditions are as follows： A has best dispersive activity, optimum dispersant amount was 21% part（based on 100 parts melamine） ; urea： melamine= 3 ：0. 85 The solidify reaction temperature was 280-300℃ and reaction time was 60-70min The hydrolysis reaction temperature was 100-105℃ and reaction time was 10h;Under the optimum reaction conditions the purity of product can be up to 99. 6%,and the yield can be up to 94.7 %.
