Document Type and Number:
WIPO Patent Application WO/2022/007455
Kind Code:
A1
Abstract:
A modified hydroxyethyl methyl cellulose for reinforced ceramic tile glue, prepared from the following mass percentages of raw materials: 54%-94% of hydroxyethyl methyl cellulose, 5%-40% of starch ether, 0.5%-3% of dispersant, and 0.5%-3% of rheological agent; the hydroxyethyl methyl cellulose is prepared from cellulose powder, a particle base, a liquid base, chloromethane, and ethylene oxide. The preparation method for the modified hydroxyethyl methyl cellulose comprises: (1) weighing the raw materials; (2) mixing the cellulose powder, the particle base, the liquid base, the chloromethane, and the ethylene oxide, implementing an etherification reaction, and then sequentially implementing neutralisation, washing, centrifugation, drying, and pulverisation to obtain hydroxyethyl methyl cellulose; and (3) mixing and stirring the hydroxyethyl methyl cellulose, the starch ether, the dispersant, and the rheological agent. The obtained product has stable quality, has the function of improving the tensile bonding strength of the ceramic tile glue, can be used for modern large size, large mass ceramic tiles, and can significantly improve the safety of using the ceramic tiles.
