Study on UV-Curing High Performance Celulose Ester Coatings

Abstract

Abstract: Celulose acetate butyrate (CAB) was grafted with anhydride，which was used to prepare the UV-curable modified celulose ester resin.The efects of active monomers and photoinitiators on the proper-ties of modified CAB were discused.Coating performance on diferent substrates were also studied.The sol-vent resistance and scratch resistance of the modified CAB were significantly improved.The hardnes could reach4H，the gloss (60°) 130，and the acetone rub test were over 400 times.

Key words: Celulose acetate butyrate, anhydride, UV-curing, solvent resistance, scratch resistance

摘要： 通过对醋酸丁酸纤维素(CAB)进行酸酐接枝改性，合成了可紫外光固化的改性纤维素酯树脂。讨论了活性稀释剂、光引发剂的选用对改性后醋酸丁酸纤维素性能的影响，并研究了不同材质表面的涂膜性能。改性的醋酸丁酸纤维素涂层在耐溶剂性、耐划伤性方面得到显著提高，其硬度可达 4H，光泽(60°)为 130，耐丙酮擦拭40次以上。
