摘要
环己酮-甲醛树脂综合性能良好,是一种新型涂料添加剂。其生产方法有三种:甲基环己酮与甲醛共缩合;环己酮与甲醛在有机溶剂和氢氧化钠存在下一步共缩合;环己酮与甲醛在碱性条件下两步合成。工业上采用第三种方法。
Cyclohexanone-formaldehyde resin has high hardness, good weatherability and resistance to oxidation, low viscosity, good luster and other advantages. It is a new type paint additive. There are three manufacturing methods: cocon-densation of methyl cyclohexanone and formaldehyde; one step cocondensation of cyclohexanone and formaldehyde in the presence of organic solvent and sodium hydrate; two step synthesis of cyclohexanone and formaldehyde under alkali condition. The third method is commercially adopted.
