摘要: 采用IR、ESCA和ESR等波谱分析手段,检测了红松木材和醇酸树脂清漆的化学基团组成,研究了木材与涂料分子之间形成涂膜的附着结合机理。研究表明,红松木材和醇酸树脂清漆之间没有发生明显的基团化学反应,但却有明显的自由基化学反应发生,从而形成一定量的化学键。本研究结果有力地支持了涂膜附着结合的“界面化学键理论”。

Abstract: With the help of advanced modern spectroscopy analytic techniques,such as IR,ESCA and ESR,the function group composition of Korean pine wood and alkyd resin varnish was determined,also the adhesion mechanism at the interface between the wood and the varnish was mainly investi-gated.The results showed that there was no remarkable chemical reaction of function group,alkyd resin varnish between korean pine wood and alkyd resin varnish,but there was noticeable chemical reaction of free radicals,so that a certain amount of chemical bond was formed.The results support powerfully“the theory of the chemical bond at the interface between the paint molecule and painted body surface”.
