Problems solved by technology

[0008] The technical problem mainly solved by the present invention is that the glazed surface wear resistance of the glazed tiles in the prior art is generally low, the hardness of the glazed surface layer is insufficient, and scratches are prone to occur, which seriously restricts its application as floor tiles. Adding crystal media with high melting point and high hardness to the glaze, such as corundum, zircon, mullite, etc., can improve the wear resistance of the glaze, but it will make the glaze devitrify, providing a kind of Preparation method of glazed tiles

Embodiment 1

[0038] Preparation of aluminum hydroxide powder:

[0039] Put 700mL of sodium aluminate solution with a mass fraction of 20% into a plastic tank, and pass carbon dioxide gas into the plastic tank at a rate of 20mL / min for 40min. After the ventilation is completed, let it stand for settling for 3h to obtain a settling mixture. In a flat disc filter, filter and remove the filtrate to obtain a filter residue, place the filter residue in an oven, heat up to 90°C, and dry for 4 hours to obtain aluminum hydroxide powder;

[0040] Preparation of dispersion glue:

[0041] The aluminum hydroxide powder was placed in a high-pressure airflow machine, and the air was pulverized for 10 minutes to obtain aluminum hydroxide ultrafine powder with a particle size of 50 μm. In the sodium solution, a colloidal liquid is obtained, and the colloidal liquid is placed in a high-speed disperser to disperse at a high speed at a rotational speed of 3000 r / min to obtain a dispersed colloidal liquid;

Abstract

The invention belongs to the technical field of building ceramic material preparation and in particular relates to a method for making a glazed brick. The method comprises the following steps: mixinga resin base material, a dispersion glue solution, vinyl trimethoxy silane, polytetrafluoroethylene powder and the like so as to obtain a composite resin wearing-resistant coating glue solution, performing ball milling on a glaze, milling balls, a sodium silicate solution and the like so as to obtain ball milling glaze slurry, and pressing a layer of the composite resin wearing-resistant coating glue solution to the surface of a finished product brick by using a double-layer mold, so as to obtain the glazed brick. According to the method, fine aluminum hydroxide powder on the surface of a composite coating can be oxidized to form an aluminum oxide protection layer, a silica long chain and an organic resin long molecular chain are mutually tangled, then the surface energy of the material can be improved, a transfer layer generated by the resin is hard to peel in a friction process, and abrasion can be alleviated; and due to adoption of the aluminum hydroxide, the interface bonding forceof a glazed brick body with a composite resin coating can be improved, the hardness of the glazed brick can be increased, the glaze slurry has good suspension, the high temperature viscosity of the glaze can be increased, the overall hardness and strength of the glazed brick can be improved, and wide application prospects can be made.

Description

technical field [0001] The invention belongs to the technical field of preparation of building ceramic materials, in particular to a preparation method of glazed tiles. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for architectural ceramics, not only pursuing their practicality, but also paying more and more attention to their decoration and functionality. [0003] Glaze is a thin layer of glass applied to the surface of the ceramic body. It is based on the performance requirements of the body, which is conducive to the proportion of natural mineral raw materials and some chemical raw materials, and is melted under the action of high temperature to cover the surface of the body. made. After the glaze is fired in the kiln, it is tightly attached to the porcelain body, which makes the porcelain densified, soft in luster, impermeable to water and air, and gives people the feeling of being bright l...
