摘要
本文制备了醛基纤维素及纤维素基希夫碱铜配合物,用于催化生漆干燥成膜。采用FT-IR、XRD、TG、SEM等现代分析技术手段对改性前后纤维素的性能和结构进行表征,并对漆膜的常规物理机械性能进行了测试。结果表明:2%含量的纤维素基希夫碱铜配合物对生漆膜具有明显的催干作用,漆膜的固化时间缩短为300 min,且漆膜综合机械性能较好,附着力(百格刀法)为5B,柔韧性为3mm,光泽度63.6。
Aldehyde cellulose and its cellulose Schiff base copper complex were prepared to catalyze the lacquer drying and film formation of.The properties and structure of cellulose before and after modification were characterized by modern analytical techniques such as FT-IR,XRD,TG and SEM,and the conventional physical and mechanical properties of the paint film were tested.The results show that 2%cellulose schiff base copper complex has obvious drying effect on the paint film,and the curing time of the paint film is shortened to 300 min with good comprehensive mechanical properties.The adhesion(hundred grid knife method)is 5 B,the flexibility is 3 mm and the gloss is 63.6.
