Cellulose ether composition applicable to ceramic tile adhesive
The invention provides a cellulose ether composition which can be used for improving various tensile and adhesive strengths of a ceramic tile adhesive and is applicable to the ceramic tile adhesive. The composition is obtained through uniformly mixing 83-89% (by weight) of cellulose ether, 5-8% (by weight) of tail-wind material and 5-7% (by weight) of calcium propionate, wherein the cellulose ether is hydroxypropyl methylcellulose ether or hydroxyethyl methylcellulose ether; and the tail-wind material is a material recovered by a deduster in a crushing procedure in a cellulose ether production process. According to the cellulose ether composition provided by the invention, part of the cellulose ether is replaced with the tail-wind material with low dissolution rate, and the tail-wind material is added into the ceramic tile adhesive, can be continuously and slowly dissolved through water absorption during the use of the ceramic tile adhesive and acts at the later stage of use of the ceramic tile adhesive, so that the water retention property of the ceramic tile adhesive at the later stage is improved; and meanwhile, calcium propionate is adopted, so that compared with single cellulose ether, the cellulose ether composition is low in cost, can improve the various tensile and adhesive strengths of the ceramic tile adhesive and is especially suitable for being added into the ceramic tile adhesive.
