本研究采用以多元羧酸类化合物为酯化剂，以无机盐为催化剂的交联体系。这一体系是新型的、水溶的、无毒害、无污染、木材交联反应未采用过的非甲醛系试剂交联体系。本文采用ＦＴＩＲ和ＣＰ／ＭＡＳ１３ＣＮＭＲ的光谱法确定了多元羧酸类化合物与木材交联反应产物的形成特征和交联反应参数。 In this study, polycarboxylic acids as esterification agent, inorganic salt as a catalyst for the crosslinking system. This system is a new, water-soluble, non-toxic, non-polluting, non-formaldehyde cross-linking reaction has not been used for non-formaldehyde reagent crosslinking system. In this paper, the formation characteristics and cross-linking reaction parameters of the cross-linked polycarboxylic acids with wood were determined by FTIR and CP / MAS13CNMR spectroscopy.
