摘要

探索了一种光引发剂接枝改性水性环氧丙烯酸树脂（EA）的制备方法。首先，通过4-羟基二苯甲酮（4-HBP）与2，4-甲苯二异氰酸酯（TDI）反应合成带异氰酸根的光引发剂中间体（HTBP），然后将HTBP接枝到EA上，再与马来酸酐反应制备自带光引发基团的水性树脂。采用NMR、FTIR分别对HTBP和EA-g-HTBP的结构进行了表征。将合成的树脂涂膜进行光固化测试，并与同类型的共混引发剂体系相比较。研究表明化学接枝型体系的固化速率、铅笔硬度、热稳定性都有所提高。

Abstract

A novel water-borne epoxy acrylic resin (EA)with photoinitiator was synthesized by grafting maleic anhydride (MAH)and a new photoinitiator HTBP prepared by the reaction of 4-hydroxy benzophenone (4-HBP)and 2

4-toluene diisocyanate (TDI）.The structures of HTBP and graft polymers were characterized by H NMR and FTIR spectroscopy.Curing time and adhesion were evaluated according to industrial standard.The film hardness was measured by GB 6739—86 (China）.The thermal properties were characterized by TGA.Adhesion and thermal properties of the grafting system were improved compared with blending system

because of good compatibility between photoinitiaor and resin.Due to the same reason

the hardness of the film could be up to 4H.Above all

the new modified resin could avoid the photolysis fragments that might cause toxicity

which meant less environment pollution and more applications.
