Title:
METHOD FOR PREPARING CELLULOSE ETHERS, CELLULOSE ETHERS PREPARED BY SAID METHOD AND ARCHITECTURAL FINISHING MATERIAL COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2018/012751
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing cellulose ethers, comprising the following steps of: (1) reacting cellulose with an alkalizing agent to obtain an alkalized cellulose; (2) etherifying the alkalized cellulose to obtain cellulose ethers in a slurry state; and (3) introducing a surfactant to the cellulose ethers in a slurry state in which the etherification reaction is complete, to cellulose ethers prepared by the method, and to architectural finishing materials comprising the same. According to the present invention, there can be provided a method for preparing cellulose ethers having improved cold water solubility, and by including cellulose ethers prepared by the method, the present invention can provide architectural finishing materials in which an amount of lump generated when mixed with cold water is minimized and the surface workability thereof is improved.
