摘　　要：用新型多元醇部分代替传统不饱和聚酯当中二元醇,用二步加料法,合成出具有体型结构的预聚物,再用带有不饱和双键的丙烯酸酯类进行封端,得出能紫外光固化的不饱和聚酯。同时,为了制备出性能最好的树脂,对其成分进行了正交实验,最终得出了附着力良好,硬度较高的,可用于木器表面涂膜的光固化(UV)胶衣树脂。并且研究其分别在高压汞灯和主波长为375nm的LED光源下,UV胶衣树脂体系的光固化动力学行为。Novel branched unsaturated polyester resin was synthesized by the polyhydric alcohols partly instead of traditional dihydric alcohol with two-step loading,and blocking with acrylic ester （with photosensitive double bond）.The resin was characterized by FT-IR spectrum and GPC.Through a set of orthogonal optimum experi-ments,we had got the best performance of the resin which had a good adhesion and great hardness on a sub-strate of wood.The UV Hg lamp and UV-LED power was used as an irradiation power to investigate the UV-curing kinetic behavior of the branched unsaturated polyester as aprepolymers.And through adj ust the formula of different initiator and content,the result shows that the prepolymer can also curing under the UV-LED pow-er,and also doing under the high pressure Hg lamp.
