A kind of stain-resistant polished tile and its manufacturing method

Abstract

The invention discloses an anti-fouling polishing brick and a manufacturing method thereof. The manufacturing method comprises the following steps: preparing materials, crushing blocky materials, performing raw material decarbonization and weathering, crushing blocky materials, homogenizing raw materials, blending materials, performing ball milling, performing screening, storing slurry, performingdeironing, performing screening, homogenizing slurry, performing deironing, performing screening, preparing slurry, performing spray drying and powdering, performing screening, storing a powder material, performing screening, performing dry powder deironing, performing stamping and material preparation, performing stamping molding, performing drying, performing sintering, performing rough polishing, and performing fine polishing, wherein multiple times of splat heating and splat cooling are implemented in the step of raw material decarbonization and weathering to simulate a weathering effect;drying is implemented by using a continuous low-temperature dehumidification process in the step of drying; and a "turning" method is implemented in the step of sintering. The anti-fouling polishingbrick has the advantages that the formula is scientific, and the raw material formula combination has remarkable energy conservation and consumption reduction; the process is advanced, organic mattersin the raw materials are removed in advance, brick blanks are subjected to "cooling method drying", air pores are not formed in the brick blanks, the sintering density of the polishing brick can be increased, the water absorption rate of a whole brick can be reduced, and the anti-fouling property of a brick surface can be greatly improved without an anti-fouling agent.

Description

technical field [0001] The invention relates to a polished tile, in particular to a dirt-resistant polished tile with ultra-low water absorption. Background technique [0002] Polished brick is a kind of bright brick made by grinding the surface of the whole body adobe body, which belongs to a kind of whole body brick. Compared with ordinary bricks, the surface of polished bricks is much smoother. In addition, because polished tiles are hard and wear-resistant, they are suitable for use in indoor spaces such as toilets and kitchens. High-temperature sintering of polished tiles has no radioactive elements. Unlike natural stones that contain individual traces of radioactive elements and are minerals without high-temperature sintering, polished tiles will not cause harm to the human body, so they are widely used. [0003] In the production of common polished tiles, the main process flow is as follows: raw materials → batching → sieving and iron removal → spray drying → storag...

AI Technical Summary

Problems solved by technology

[0023] Although the manufacturing method of the porcelain polished tile of the invention solves the technical problems of ultra-thin environmental protection, continuous release of anions and far-infrared rays, it does not solve the problem of pores and has some disadvantages: the product is not dense enough, easy to break, and has a high water permeability Lead to unsatisfactory stain resistance

For antifouling, the manufacturing method of the porcelain polished tile of this invention needs to add one deck antifouling layer when leaving the factory, such as putting water wax, this layer of antifouling layer causes the obtained porcelain polished tile to lose Full body brick effect
