| 摘 要： | 为了提高淀粉胶粘剂的耐水性和降低其生产成本,以生物油-PF(酚醛树脂)作为淀粉胶粘剂的改性剂,采用单因素分析法探讨了氧化剂种类、聚合反应温度及固化剂用量等因素对改性淀粉胶粘剂主要性能的影响。结果表明:制备改性淀粉胶粘剂的较佳工艺条件是以高锰酸钾和硫酸为氧化剂,聚合反应温度为75℃,w(固化剂)=12%(相对于胶粘剂总质量而言);在较佳工艺条件下制成的改性淀粉胶粘剂具有良好的胶接性能,并且克服了传统淀粉胶粘剂遇水易开胶、传统PF胶粘剂中游离醛释放量较高等缺点,可广泛用于Ⅱ类胶合板的生产。

| Abstract: | In order to improve water resistance and reduce production cost of starch adhesives,so a bio-oil-PF(phenolic resin) modified starch adhesive was prepared.The influences of oxidant types,polymerization temperature,curing agent contents and other factors were discussed on main performances of modified starch adhesive by single factor analysis method.The results showed that the optimal process conditions of preparing modified starch adhesive were obtained when KMnO4 and H2SO4 were used as oxidants,polymerizati... |
