摘要
在竹胶合板的胶膜纸生产中，油酸主要是作为一种脱膜剂使用的，而它对胶粘剂的表面活化作用却少有研究，以致在生产中，油酸的加量缺乏科学、合理的根据．油酸分子结构的两亲性，使它具备了作为表面活性剂的基本条件．这项研究通过不同的油酸加量，对胶粘剂的浸渍特性和胶膜纸上胶量所产生的不同影响，以及油酸和乙醇施加效果的比较，证明了油酸对ＰＦ树脂胶粘剂具有表面活化作用．根据试验结果分析，在ＰＦ树脂胶粘剂中加入０．４％～０．８％的油酸是比较适宜的，而加量为０．４％时，胶膜纸的上胶量达到最大值．此项研究仅对油酸对半醇溶性的ＰＦ树脂胶粘剂的表面活化作用作了初步探讨，其表面活化作用的机理尚待进一步研究．
In the production of plybamboo film adhesive,oleic acid is mainly used as a kind of release agent;its surface active function for PF resin adhesive is scarcely studied.As a kind of biclose molecule,oleic acid possesses a fundmental nature as surface active agent.The study proves the objectiveness of the surface active function of oleic acid for PF adhesive by applying different oleic acid quantities to PF adhesive, analysing their effects on the immersion property of PF adhesive and on the adhesive quantity obtained on film adhesive.The study also compares the application results of oleic acid and alcohol to PF adhesive.According to the analyses of experiment results,the proper application quantity of oleic acid to PF adhesive is 0.4%0.8%,and when it is 0.4%,the adhesive quantity obtained on film adhesive can get the largest value.The mechanism of the surface active function of oleic acid for PF adhesive needs to be further studied.
