一、引言中国漆是一种优良的天然涂料,但由于其结构复杂及有毒性,这对中国漆的研究与应用极不方便,黄葆同等曾对中国漆结构与氧化反应进行过一些工作,国外也曾研究过不同品种的漆酚结构,但对深入了解中国漆的结构及其与性能的关系都很不够,本文用核磁共振方法研究中国漆中饱和漆酚及漆酚的结构,从而对影响中国漆性质的因素以及决定中国漆优劣的条件有比较明确的认识,以便为鉴定中国漆的质量和改进中国漆的性能提供必要的根据。
I. Introduction Chinese lacquer is an excellent natural coating. However, due to its complicated structure and toxicity, it is extremely inconvenient to research and apply Chinese lacquer. Huang Baochun has conducted some work on the Chinese lacquer structure and oxidation reaction. Foreign countries have also studied different varieties of urushiol structure, but to understand the Chinese paint structure and its relationship with the performance are not enough, this paper uses NMR methods to study the structure of saturated urushiol and urushiol in Chinese lacquer, The factors influencing the properties of Chinese lacquers and the conditions for determining the merits of Chinese lacquers have a clearer understanding so as to provide the necessary basis for the identification of the quality of Chinese lacquers and the improvement of the properties of Chinese lacquers.
