摘要
以十六碳酰氯(棕榈酰氯)为酰化剂与三聚氰胺进行反应,制备了十六碳酰化三聚氰胺(PM),并优化了反应条件;探究了棕榈酰氯、草酰氯、磺酰氯及丙烯酰氯四种酰化剂,制备得到相应的酰化三聚氰胺,对比了反应条件和产物性能;最后对比了密胺树脂(MF)以及棕榈酰化密胺树脂(PMF)的性能.用FT-IR、1H-NMR以及SEM表征分析了PM的结构,用TGA研究了PM的热稳定性.结果表明,该合成方法以及纯化方法产率高(90%),产物热分解温度高(367.4℃),PM粉末具有疏水性,其水接触角最高达 143°.PMF树脂比MF树脂具有更高的固含量(59.8%)和更高的粘度(150.6 mPa·s),对MF树脂后续的研究应用有着重要意义.
Abstract
The reaction between melamine and hexadecanoyl chloride(palmitoyl chloride)as an acylating agent resulted in the production of hexadecanoylated melamine(PM)after optimizing the reaction conditions.Four acylating agents,namely palmitoyl chloride,oxaloyl chloride,sulfonyl chloride,and acryloyl chloride,were used to obtain the corresponding acylated melamine.The reaction conditions and product properties were compared,followed by a comparison of the properties of the dermatomimetic resins(MFs)and palmitoylated dermatomimetic resins(PMFs).Finally,a comparison was made between the properties of MF and PMF.The PM structure underwent analysis through FT-IR,1H-NMR,and SEM characterization.Additionally,the thermal stability of PM was studied using TGA.The results indicate that the synthesis and purification method produced a high yield(90%)and a high thermal decomposition temperature(367.4℃).Furthermore,the PM powder exhibited hydrophobicity with a water contact angle of up to 143°.The PMF resin has a higher solids content(59.8%)and viscosity(150.6 mPa·s)compared to MF resin,which is significant for future research and application of MF resin.
