采用改进的一步法合成双酚A型环氧树脂,阐述了合成反应机理、改进法合成反应的步骤,探讨了不同原料配比对树脂性能的影响,反应温度、氧化钠浓度对环氧值的影响以及水洗条件的优化等。并经红外光谱表征和性能测定,采用的合成工艺方法和产物结构是正确的,且工艺过程无毒无害、便于操作,产物纯度更高、色泽更透明。

The modified one-step method is used to synthesize bisphenol A epoxy resin. This paper introduces the reaction mechanism and the reaction steps, and investigates the influence of different materials ratios on resin property, and the influence of reaction temperature and sodium oxide concentration on epoxy value together with the optimization of washing condition. Through IR spectrum characterization and properties determination, it is showed that the method and structure is suitable, the technological process is non-toxic and harmless and convenient to operate, and the product is of higher purity and transparency.
