Preparation method of porcelain deformation-resistant glazed tile and prepared porcelain deformation-resistant glazed tile

Abstract

The invention discloses a preparation method of a porcelain deformation-resistant glazed tile and the prepared porcelain deformation-resistant glazed tile. The preparation method of the porcelain deformation-resistant glazed tile comprises the following steps of: A, preparing deformation-resistant glaze from deformation-resistant glaze raw materials in proportion; b, obtaining cover glaze; c, applying the cover glaze obtained in the step B to the upper surface of a porcelain tile green body to form a cover glaze layer; d, applying the deformation-resistant glaze obtained in the step A to the bottom surface and / or the side surface of the porcelain tile green body obtained in the step C to form a deformation-resistant glaze layer; and E, drying and firing the porcelain tile green body obtained in the step D. According to the technical scheme, the preparation method of the porcelain deformation-resistant glazed tile is beneficial to preventing the deformation-resistant glaze from fallingoff. According to the porcelain deformation-resistant glazed tile prepared by the preparation method of the porcelain deformation-resistant glazed tile, the deformation-resistant glaze is applied to the tile body, so that the bottom surface tone of the finished glazed tile is consistent with the tone of the side surface and / or the top surface of the finished glazed tile, and meanwhile, the deformation degree of the glazed tile product can be stabilized.

Description

Technical field [0001] The invention relates to the technical field of building ceramics, in particular to a method for preparing a porcelain anti-deformation glazed tile and a prepared porcelain anti-deformation glazed tile. Background technique [0002] Since the production process of glazed tiles is sintered after applying glaze on the green body layer, because the glazed surface layer bears the decorative effect, it is often produced with better raw materials. In order to reduce costs, most of the green body layers use cheap raw materials. The difference in the quality of the raw materials of the body layer leads to different hue between the bottom and the face of the finished body, commonly known as "two-layer skin", especially the whiteness and oxidation degree are obviously different, making the bottom hue of the finished ceramic tile and the hue of the side and top surface It's all different. [0003] Nowadays, wide-body roller kilns are widely used in the production of gl...

Problems solved by technology

[0004] In addition, the bottom of the brick adobe generally forms geometric stripes when it is pressed and formed. The density of the ribs of the geometric stripes of the brick and the bottom of the grid is inconsistent, and the shrinkage of the ribs and the bottom of the grid is inconsistent during firing. It will have a direct impact on the flatness of the bricks exiting the kiln at the same time, and often cause a row of bricks parallel to the kiln mouth to have a large and different shrinkage, and the left, middle and right products will have inconsistent concave and convex deformations. There are "arch" and "concave" deformation and degradation defects, which seriously affect the product quality
