Burning-free imitating natural stone and preparation method thereof

Abstract

The invention discloses burning-free imitating natural stone. The burning-free imitating natural stone is characterized by comprising a blank, a middle texture layer and a surface protection layer, wherein the middle texture layer and the surface protection layer are arranged on the blank, and the middle texture layer comprises at least one printed texture layer and / or cloth texture layer. The burning-free imitating natural stone is simple in structure and convenient to produce and process, and compared with products of the same type, the burning-free imitating natural is higher in plasticity, better in natural stone imitating effect and more excellent in performance.

Description

technical field [0001] The invention relates to the technical field of natural stone imitation, and more specifically relates to an unfired imitation natural stone and a preparation method thereof. Background technique [0002] At present, in the production process of ceramic wall and floor tiles, tiles with imitation natural stone texture and imitation natural stone have gradually become the mainstream, and are more and more respected by consumers. The preparation process of common ceramic tiles imitating natural stone texture includes: 1. Preparation of green body raw materials: making conventional ceramic tile raw materials into a mixture with a certain moisture content; 2. Distributing the mixture in the solid material box to form mud 3. Spread a layer of color powder on the mud layer to form a powder layer; 4. Stamping to make bricks; 5. Firing; 6. Polishing. Because ceramic tiles imitating natural stone texture generally need to be fired at high temperature, they poll...

AI Technical Summary

Problems solved by technology

Because ceramic tiles imitating natural stone texture generally need to be fired at high temperature, they pollute the surrounding environment very much; moreover, there are only two common preparation methods for natural stone texture ceramic tiles, which are screen printing and grid striped fabric. Compared with the texture lines of natural stone, the texture lines have the defects that the lines are too thick, rigid, and poor in simulation

[0003] The common preparation process of imitating natural stone includes: raw material homogenization-mixing-cloth-forming-curing-polishing. Although high-temperature calcination is not required, since all raw materials are pressed and formed by a press at one time, the mechanical properties of the product It mainly depends on the level of the press, and has high requirements for production equipment; moreover, the texture formation of its imitation natural stone depends on the method of cloth and the configuration of the dough, the texture formation process is uncontrollable, and it is difficult to obtain the ideal natural stone texture
