玉米面粉粘合剂的合成及性能研究

Study on Synthesis of Corn Adhesive and its Properties

以玉米面粉为原料，ＮａＣｌＯ为氧化剂，合成了价格低廉、粘接性能良好、不易凝胶、粘度稳定的粘接纸张、纸板用粘合剂。其最佳反应条件是：反应温度３０℃，玉米面１０ｇ，ＮａＣｌＯ１．９ｇ，ＮａＯＨ０．８ｇ，ＮａＳ２Ｏ３０．０２５ｇ。

Using corn powder as row material an adhesive for adhering paper and paperboard was prepared with sodium hypochlorite as oxidizer. The price of this adhesive was low and the adhesion was good. During storage at room temperature it was not easy to gel and its viscosity kept steady.The optimum formulation was cron 10 g,sodium hypochlorite 1.9 g,sodium hydroxide 0.8 g;sodium thiosulfate 0.025 g;borax 0.15 g ;water 70 ml and the reaction temporature was 30.
