Beschreibung
Zusammenfassung:	The present disclosure discloses a modified hydroxypropyl methyl cellulose for an enhanced ceramic tile adhesive, which is prepared from the following raw materials by mass percent: 54%-94% of hydroxypropyl methyl cellulose, 5%-40% of starch ether, 0.5%-3% of dispersing agent and 0.5%-3% of rheological agent, wherein the hydroxypropyl methyl cellulose is prepared from cellulose powder, granular caustic soda, liquid caustic soda, chloromethane and propylene oxide. A preparation method includes: (1) weighing the raw materials; (2) mixing the cellulose powder, the granular caustic soda, the liquid caustic soda, the chloromethane and the propylene oxide, carrying out etherification reaction, and then sequentially carrying out neutralization, washing, centrifugation, drying and crushing to obtain the hydroxypropyl methyl cellulose; and (3) mixing and stirring the hydroxypropyl methyl cellulose, the starch ether, the dispersing agent and the rheological agent to obtain the modified hydroxypropyl methyl cellulose.
