Based on existing synthetic methods of hydroxypropyl methyl cellulose, by using nitrogen protection alkalization and step-by-step etherification method, high viscosity of hydroxypropyl methyl cellulose was prepared. The hydroxypropyl methyl cellulose (HPMC) produced with this method has good dispersion performance in cold water, high viscosity, thickening water performance, and is suitable for the production of construction glue, can be also used in laying bricks or stones wall, plaster, paint, sealing construction, and is also suitable for dry mortar.
