Abstract

The invention relates to the technical field of production of ceramic tiles of building materials, and particularly relates to a preparation method of a thermal insulation easy-to-cut ceramic tile. Arecycled foam sheet particle is added in the ceramic tile, and EPS in the foam sheet particle produces a foaming effect in the sintering process of the ceramic tile. Sodium lignosulphonate extracted from a corncob reduces the surface energy of the ceramic tile, the stain is prevented from invading into a micropore to cause blockage, and the purpose of thermal insulation is fulfilled. The main rawmaterial is red mud, aluminum oxide exists in the red mud in the form of a crystal fiber, the crystal fiber is longitudinally oriented in the ceramic tile after being compressed and sintered, the direction of cutting stress and the orientation direction of the crystal fiber are the same when the crystal fiber is cut by a cutting machine, the breakage of the crystal fiber is avoided in the cutting,the expansiveness of the foam sheet particle is good, the wear degree of a cutting tool is also reduced in the cutting, and the purpose that the ceramic tile is easy to cut is fulfilled.

Description

technical field [0001] The invention relates to the technical field of ceramic brick production of building materials, in particular to a preparation method of thermal insulation and easy-cut ceramic bricks. Background technique [0002] Ceramic bricks are plate or block ceramic products produced from clay and other inorganic non-metallic raw materials through molding and sintering processes, and are used to decorate and protect the walls and floors of buildings and structures. It is usually shaped by dry pressing, extrusion or other molding methods at room temperature, then dried and fired at a certain temperature. [0003] Generally, ceramic wall tiles are rectangular, and when laying, there will be positive corners at the corners of the wall. At present, there is a method of cutting and chamfering ceramic tiles on site when dealing with external corners. However, due to the fragile ceramic material and high hardness, it is difficult to cut, the efficacy is low, and the q...
