死漆研磨法制备一种快干漆的研究
Quick-drying Lacquer Prepared by Grinding Method
摘要
Abstract
A quick-drying lacquer ( QDL) was prepared from the dead lacquer and titanium compound grinded at ambient and solvent-free condition. The structure and properties of the products were studied by IR, SEM and TG. The influence of main specific components of raw lacquer on the curing was discussed. The results showed that urushiol was the main component for film formation in the grinding process. The water-in-oil emulsion of dead lacquer was damaged in grinding process. When the mole ratio of titanium compound to urushiol was 1:2, the drying time was shortest. The surface drying time and hard drying time of the obtained film were 1. 5 and 6 h, respectively, which were far more quickly than natural lacquer . QDL1, QDL2 and QDL3 were obtained through grinding process when the mole ratio of titanium compound to urushiol were 1:2, 1:3 and 1:4. All the obtained films had high gloss, the gloss values were 50 higher than that of natural lacquer films. The temperatures at 5 % weight loss, 10 % weight loss and maximum weight loss of QDL1 were 289, 346 and 475 ℃, respectively, which was higher than natural lacquer on counterpart time by 21, 35 and 28 ℃. This indicated that the thermostability of the QDL films was better than that of laccase-catalyzed lacquer films.关键词
