摘要
为解决淀粉代替石油产品制取胶粘剂胶接木质材料后耐水性差的问题,该研究用玉米淀粉、聚乙烯醇、异氰酸酯和羧基丁苯胶乳等原料合成胶粘剂过程中各因素对胶接后湿强度的影响规律。采用二次旋转正交组合试验方法设计试验,并用SAS软件和Matlab软件处理数据,分析了原料配方和反应温度对胶粘剂胶接木质材料后湿强度的影响,优化了淀粉胶粘剂的工艺参数,淀粉质量分数13%,聚乙烯醇质量分数4%,异氰酸酯质量分数5%,胶乳质量分数3%;反应温度58℃。并通过扫描电子显微镜进行了微观结构分析,揭示了淀粉胶粘剂湿强度提高的机理。
In order to solve the problem of poor water resistance of the starch-based adhesive after bonding wood materials,the impact of various factors on the wet strength was researched in the course of synthesizing adhesive with corn starch,polyvinyl alcohol,isocyanate and carboxylic styrene butadiene latex.The method of quadratic orthogonal rotation combination experiment design was applied,and SAS software and Matlab software were used to process data.Effects of the material and reaction temperature on wet strength of adhesive after bonding wood materials were analyzed to optimize technological parameters of starch-based adhesive The optimal conditions were as follows：starch content 13%,polyvinyl alcohol 4%,isocyanate content 5%,latex content 3%;reation temperature 58℃.The microstructure of starch-based adhesive was analyzed by scanning electron microscope to reveal the mechanism of the wet strength enhancement.
