Pseudo-natural stone polished tile and preparation process thereof

Abstract

The invention relates to a pseudo-natural stone polished tile and a preparation process thereof. The preparation process comprises the following steps: A, preparing block-shaped materials; B, coating the block-shaped materials with slurry: coating the surface of the block-shaped materials obtained in step A with a layer of slurry by virtue of a spraying manner, and obtaining the block-shaped materials coated with the slurry layer; C, distributing materials: first distributing the block-shaped materials in a distributing frame, and then filling the distributing frame with a surface material; D, pre-pressing; E, distributing a base material; F, pressing, and obtaining a green body; and G, sintering and polishing, thus obtaining the pseudo-natural stone polished tile. According to the pseudo-natural stone polished tile and the preparation process thereof, by adopting a reverse way, the block-shaped material coated with the slurry layer and the ordinary ceramic powder are jointly used for pressing and sintering the green body, and a polished tile with a large block-shaped decoration effect can be obtained; and moreover, the boundary of the block shape is clear, the decoration effect has good abrasion resistance, and the decorative surface can be abraded as the application period is increased to be more approximate to the natural state of natural stone.

Description

technical field [0001] The invention relates to the technical field of building ceramics, in particular to a natural stone imitation polished brick and a preparation process thereof. Background technique [0002] Modern architecture and decoration industry are using more and more imitation natural stone bricks, and the requirements for imitation natural stone bricks are becoming more and more wild. Various types of imitation natural stone bricks are also emerging in large numbers. The porcelain polished bricks currently on the market All are produced by "dream fabric", "multi-tube fabric", "micro-powder multiple fabric" and other technical means; in order to achieve the effect of imitating natural stone texture. These process methods all use the press mold frame as a filling material plane, and the material is scraped and leveled at one time. The proportions and changes of various materials with different properties and colors on different layers of the filled material are r...

AI Technical Summary

Problems solved by technology

These process methods all use the press mold frame as a filling material plane, and the material is scraped and leveled at one time. The proportions and changes of various materials with different properties and colors on different layers of the filled material are roughly the same, and there is no process control and freedom. Adjust the property of the change of raw materials at each level, so it is impossible to form the stone gap texture that people want to see with clear boundaries, large block lines, and blocks. It can only form color block changes with poor controllability and a small amount. short grain

[0003] At present, the imitation natural stone large block pattern existing in the market is formed by cloth fine powder to form a separation gap. Since it is all powder cloth, the boundary between the gap and the block is not obvious, and the boundary is not clear. The other has particles. The imitation natural stone brick with a decorative effect like rice grains has a decorative effect of rice grains, which is formed by distributing rice-shaped decorative particles on the fabric layer to form a decorative effect of small particles with a long diameter less than 4mm (wherein the long diameter refers to the longest diameter of the particle. ), its particle diameter is small, and it can only act as crystal particles contained in the stone, but cannot be connected to form the texture of the stone gap, which has certain limitations
