Abstract: The present disclosure relates to the technical field of building additives, and in particular to a preparation method of modified starch ether for improving the anti-sliding property of a ceramic tile adhesive. The preparation method includes chemical modification of subjecting starch to one-step etherification to obtain starch ether, followed by physical modification. In the preparation method, the cumbersome multi-step etherification in existing methods for preparing modified starch ether is avoided, and only one-step etherification is used to obtain modified starch ether of better properties. Because physical modification is added, the obtained product can significantly improve the anti-sliding property of a ceramic tile adhesive. Moreover, the conditions for one-step etherification are significantly different from the prior art.
