摘 要:
通过加入添加剂对淀粉接枝醋酸乙烯酯胶粘剂进行性能优化。研究了胶粘剂的粘结强度与接枝参数的关系,并在此基础上加入添加剂,研究添加剂的加入对接枝参数的影响。通过单因素试验确立接枝参数最大的反应条件为添加剂的加入量0.2g,加入时刻为接枝反应开始后2h,滴加质量浓度为0.05g/mL,滴加净时间为20min。研究了添加剂对粘结强度和耐水性的影响,并通过响应面分析试验得出最佳反应条件:当加入量为0.205g、滴加时间为19min时,胶粘剂的粘结强度和耐水性达到最大值。[著者文摘]

Abstract:
Additive was added to improve the properties of grafted copolymer of starch with vinyl acetate. The relationship between adhesive strength and grafting parameters was studied, and then the affect of additive on grafting parameters was also studied while it was added. The optimal reaction condition corresponding to the largest grafting parameters was listed as follows. 0.2 g as adding amount, 2 h after grafting as adding time, 0.05 g/mL as adding concentration, and 20 min as net adding time. The affect of additive on adhesive strength and water resistance were studied, and response surface modeling was applied to get the ultimately optimal reactive condition that the compressive shear strength and water resistance got maximum value as 0. 205 g additive was added for 19 min.[著者文摘]
