使用化学工作站对制备得到生物基聚氨酯薄膜的防腐性能进行分析。生物基聚氨酯制备工艺:取乙酸丁酯和木质素或改性木质素,然后加入13 g羟基丙烯酸树脂,6.5 g固化剂,1 wt%有机锡催化剂,混合后室温下固化得到
The anticorrosive properties of the prepared bio-based polyurethane films were analyzed by chemical workstation. Preparation process of bio-based polyurethane: Take butyl acetate and lignin or modified lignin, then add 13 g hydroxyl acrylic resin, 6.5 g curing agent, 1 wt% organotin catalyst, and then cure at room temperature.
