Leak-proof ceramic tile and preparation method thereof

Abstract

The invention discloses a leak-proof ceramic tile and a preparation method thereof. The leak-proof ceramic tile is prepared from the following matching components: 12%-18% of magnesia, 10%-20% of Xiangyin mud, 10%-18% of Baixiang sand, 3%-8% of Xinyang soil, 5%-8 % of high-alumina soil, 15%-20% of Hengyang sand, 12%-18% of Fushan sand, 6%-15% of waste residue and 0.5%-2% of an additive. The ceramic tile is obtained by ball milling of raw materials, spray drying, powder dry pressing die molding, green body drying, glazing decoration and oxidation burning at 1130 DEG C-1160 DEG C. According to the leak-proof ceramic tile and the preparation method thereof, by increasing the height of a convex peak and widening the width of a flat groove, the drainage effect is improved; and meanwhile the heights of steps of overlap positions are increased, so that rainwater can also be blocked in the case of a strong wind, and the rainwater can not cause water leakage by flowing backward.

Description

technical field [0001] The invention relates to roof building materials, in particular to a corrugated fired tile. Background technique [0002] In addition to the decorative effect of ceramic tiles, the use requirements of ceramic tiles are the sidewind resistance, rain resistance, leakage prevention, heat insulation, impermeability and other performances of ceramic tiles that need to be considered in the development process of ceramic tile products. performance parameters. For the anti-leakage and impermeability of ceramic tiles, the anti-leakage effect of some existing anti-leakage structures on ceramic tiles is not ideal under the severe weather conditions of continuous rain, heavy rainfall and side wind. [0003] In actual production, the size of each part of the existing corrugated ceramic tiles is relatively small due to firing and molding. For example: in order to facilitate molding and demoulding, the convex peak of the wave-shaped ceramic tile is generally not hi...

AI Technical Summary

Problems solved by technology

For example: in order to facilitate molding and demoulding, the convex peak of the wave-shaped ceramic tile is generally not high, the highest is only 22mm, and the width of the flat groove is not wide, resulting in unsatisfactory drainage; It is because the steps are too high and cracks are easy to appear, resulting in defective products. In severe cases, it will break and affect the use. In this way, water leakage will occur in bad weather with heavy rainfall and crosswinds.
