一种新的漆，混合R。将漆树（中国生漆，漆酚）与漆黑（泰国生漆，漆酚）混合，制备了漆黑（中国生漆，漆酚）与漆黑（泰国漆酚）的混合物。主要性能，粘度，干燥时间，干燥机理，和作为涂层材料的漆膜的性质，进行了检查。此外，结合二维核磁共振（NMR）和场解吸质谱（FD-MS）的研究结果，探讨了漆酚和漆酚之间发生转移自由基反应的机理。配制了一种含70% R. vernicifera和30%的M.干燥时间与100%红曲霉基本相同。结果表明，在干燥时间自动记录仪中，Vernicifera具有较高的表面光滑度和光泽度，并对其分子量分布、抗紫外性和玻璃化转变温度（T（g））进行了详细的研究。(C)2011 Wiley Periodicals，Inc.应用聚合物科学杂志121：2734-2742，2011
A new lacquer that blends R. vernicifera (Chinese lacquer, urushiol) with Melanorrhea usitata (Thai lacquer, thitsiol) was prepared. The main properties, viscosities, drying times, drying mechanism, and the nature of the lacquer films as a coating material, were examined. In addition, the mechanism of transfer radical reaction that occurred between urushiol and thitsiol is discussed based on the results of two-dimensional nuclear magnetic resonance (NMR) and field desorption mass spectrometry (FD-MS) measurements. A blended lacquer with 70% R. vernicifera and 30% M. usitata showed almost the same drying time as 100% R. vernicifera as examined in an automatic drying time recorder but had higher surface smoothness and gloss. Furthermore, the molecular weight distribution, UV resistance, and glass transition temperature (T(g)) also were investigated in detail. (C) 2011 Wiley Periodicals, Inc.
