摘要
为实现包装人造板的芳香功能,研究了不同比例的芳香剂对脲醛树脂常规性能的影响。结果表明,芳香剂的加入提高了脲醛树脂的酸性和黏度,缩短了脲醛树脂的固化时间,提高了脲醛树脂在竹片表面的润湿性能,但对胶层剪切强度无明显影响;此外,檀香、茉莉、馥花以及薰衣草4种芳香剂的加入,并不影响脲醛树脂的特征峰。
In order to realize aromatic function of packaging wood based panel, the influences of aromatic agent ＇s addition dosage on performance of urea-formaldehyde resin were studied. The results showed that acidity and viscosity of urea-formaldehyde resin increased and the panel surface property was improved while curing time reduced, but these did not affect shear bond strength of urea-formaldehyde. Infrared spectrum analysis showed that the characteristic peak of urea-formaldehyde was not influenced by addition of any kind of aromatic agents.
