以淀粉作为基料生产的内墙涂料的方法早有报道，笔者研制的LK－881变性淀粉内墙涂料采用膨润土和变性淀粉为主要原料，通过糊化、交联等反应生产的内墙涂料性能良好，克服一般淀粉涂料的不足。1主要原料选择钙基膨润上水化能力弱，悬浮性较差、易沉淀；钠基膨润土的水化能力强
The method of producing interior wall paints using starch as a base material has long been reported. The interior wall paint properties of LK-881 modified starch interior wall paints produced by the authors are based on bentonite and modified starch as main raw materials, and are produced by gelatinization, cross-linking and other reactions. Good, to overcome the deficiencies of the general starch coating. 1 The main raw materials choose calcium-based swelling on the weak hydration, poor suspension, easy to precipitate; sodium bentonite hydration ability
