Ceramic tile blank and preparation method
The invention relates to a ceramic tile blank and a preparation method. CMC (Carboxymethylcellulose), PVA (Polyvinyl Acetate), sodium polyacrylate and sodium alginate of which the mass ratio is (2 to 3):(0.5 to 0.8):(15 to 20):(0.01 to 0.03) are mixed, and then water is added, so as to obtain a body enhancer solution of which the mass fraction is 5 to 8%; hard materials and soft materials are uniformly mixed to be added to a granulator, the body enhancer solution is added to the granulator, powder granulated by the granulator is dried until the moisture content is 5 to 8%, and then screening is performed, so as to obtain the ceramic tile blank. All components of the ceramic tile blank are suitable for a dry pulverizing process, compared with a general dry granulating technique, the ceramic tile blank has the advantages of stable quality and good granule fluidity, after a ceramic tile sample is fired, the average breaking strength reaches 38 to 55 MPa, and the water absorption is less than or equal to 0.5%.
