生漆改性主要是经过多次严格地过滤，除去杂质，并在常温脱水活化，取其主要成分漆酚进行的化学改性，即得改性生漆。上个世纪，曾维聪等首先将漆酚与甲醛进行缩合反应制备漆酚缩甲醛树脂获得成功，这是中国生漆改性研究的一个重要进展。
漆酚与醛的反应更重要的意义在于它是漆酚改性的一种有力手段，以醛产生的亚甲基为桥可将漆酚与其它活性基团连在一起，赋予生成物以独特的性质，可以改善生漆的各项弊端，可以直接使用，也可以作为改性生漆合成过程的中间体。
某一改性生漆与天然生漆的性能如表1。

결과 (영어) 2:

Lacquer modified mainly through several rigorous filtration to remove impurities, and dehydration at room temperature activated, chemically modified whichever is the main component of urushiol carried out, that was modified lacquer. The last century, Zeng Cong urushiol first condensation reaction with formaldehyde Formaldehyde resin urushiol successful, this is an important development of Chinese lacquer modification.
More significant reaction with an aldehyde urushiol that it is a powerful means of urushiol modified to aldehyde to produce methylene bridge may be urushiol with other active groups together, giving a unique product The nature, can improve the drawbacks of lacquer can be used directly or as an intermediate in the synthesis of modified lacquer.
A modified natural lacquer and lacquer properties as shown in Table 1.

Improvement of raw lacquer is mainly through many strict filtering and removing impurities and in room temperature dehydration activation, take the main component of lacquer phenol chemical modified, the modified raw lacquer. The last century, Zeng Wei Cong first of urushiol and formaldehyde for condensation reaction for preparation of urushiol formaldehyde resin to succeed, this is an important progress in the research of Chinese lacquer modified.
of urushiol and formaldehyde reaction is more important significance is that it is a powerful tool for modified urushiol, to produce aldehyde methylene bridge can and other active groups of Urushiol even together, giving the product with unique properties and can improve the drawback of the lacquer, can directly use.Can also be used as intermediates during the synthesis of modified lacquer.
a performance of modified natural lacquer and lacquer such as table 1.
