| 中文摘要 | 采用盐酸为催化剂、过硫酸铵为氧化剂,制备酸解氧化淀粉乳液。淀粉在酸解的同时进行氧化,缩短了反应时间,提高了反应效率。经单因素分析试验,确定优化工艺条件:淀粉乳液质量百分数35%,反应时间1h,盐酸浓度0.5mol·L-1,反应温度55℃,过硫酸铵用量为淀粉干基质量的2.25%。酸解氧化淀粉具有酸解淀粉与氧化淀粉的双重性质。产物具有黏度低、浓度高、抗凝沉性好特点,可用于木材胶黏剂的制造。; The acid-thinned and oxidized starch latex was obtained by adopting hydrochloric acid as catalyzer and ammonium persulfate as oxidant.Starch was acid-thinned and was oxidized meanwhile,which shortens reaction time and enhances reaction velocity.The optimum technology conditions obtained by analysis experiment of single element are:35% of starch latex concentration,1 h of reaction time,0.5 mol·L-1 of hydrochloric acid concentration,55 ℃ of reaction temperature,2.25% of amount for dry starch mass.Acid-thinned and oxidized starch has double properties of acid-thinned starch and oxidized starch.The reaction-product had good properties such as low viscosity,high concentration,low retrogradation and would be used to prepare for wood-adhesives.; 科技部农业转化资金项目(2007GB2B10078); 吉林省科技发展计划重点项日(20060401-2); 国家重点基础研究项目(973计划2004CB719706) |
