基于一步法合成水性多官能团环氧树脂及其与皮胶原纤维相互作用的研究

本研究着眼于常规铬鞣所产生的污染问题，采用一步法，即基于自由基共聚理论，以含双键环氧单体与乙烯基类单体为原料直接合成系列水性多官能团环氧树脂。探究官能团类型、单体种类及配比等因素对水性环氧树脂分子量大小及其分布的影响规律，建立水性环氧树脂聚合动力学方程。将其应用于对皮胶原纤维的改性中，获得环氧树脂中官能团类型、分子量大小及其分布对改性皮胶原纤维性能的影响规律，建立水性环氧树脂与胶原纤维相互作用的机理模型，进而揭示其鞣制机理。该研究简化了水性环氧树脂的合成工艺，为皮胶原纤维的改性提供了新的思路，对实现无铬鞣具有重要的意义。

This study focuses on the problem of pollution produced by conventional chrome tanning, and intends to synthesis a series of waterborne multifunctional epoxy resin through one-step method based on the theory of free radical copolymerization, which take the epoxy monomer containing a double bond and vinyl monomers as the raw material. Explore the effect of group and the type and ratio of monomer on molecular weight and its distribution law of waterborne epoxy resin. Establish the waterborne epoxy resin polymerization dynamics equation. The waterborne epoxy resin was used to modify the leather collagen. Get the effect rule of group type and the size of molecular weight and its distribution on the properties of modified leather collagen. Build the interaction mechanism model of waterborne epoxy resin with collagen fiber and reveal the tanning mechanism. This study simplifies the synthesis process of waterborne epoxy resin and provides a new train of thought of leather collagen modification. Furthermore, it has the vital significance on chrome-free tanning.
