[0003] Among them, the decorative surface of the ceramic tile is the brick surface, and the construction surface is the brick back. The back pattern of the ceramic tile is formed by pressing at four major angles, namely, flat angle, obtuse angle, right angle and acute angle. The existing ceramic tile adopts flat angle and obtuse angle technology to press and form an arc back pattern. The ceramic tile is generally paved on the ground or wall with adhesive or cement slurry, and the bonding surface of the existing ceramic tile is often not provided with a number of right-angle raised criss-cross anti-slip ribs, convex tenons or a number of right-angle recessed criss-cross anti-slip grooves, concave mortise. This kind of ceramic tile is completely fixed to the wall or ground by viscosity, with low adhesive force and insufficient adhesive strength. The ceramic tile is easy to loosen or fall off after a long time of use. At the same time, the raised criss-cross anti-slip ribs and convex tenons are set, and a gap is formed in the middle when stacked during the production and transportation process. The ceramic tile is easily shattered by the convex ribs. There is another kind of dovetail groove back pattern ceramic tile formed by pressing and forming a flat angle and acute angle technology, but the process is complicated during production demoulding.
