Problems solved by technology

However, there are also many problems in the above process: on the one hand, the purpose of the glaze layer is to seal the pores on the surface of the ceramic body in the preparation of self-cleaning ceramic products. The glaze layer has no other functions, but the processing cost of the glaze layer is relatively high. Lead to an increase in product cost; on the other hand, the coating formed by self-cleaning materials such as nano-titanium oxide is coated on a smooth glaze layer, and the coating of the self-cleaning material has poor bonding with the glaze layer, and the coating of the self-cleaning material and The glaze layer does not bite each other, so in the self-cleaning application space such as outdoor, kitchen or bathroom, the product application is affected due to the poor thermal stability of the product

preparation example Construction

[0089] In a second aspect, in at least one embodiment, a method for preparing the above-mentioned self-cleaning ceramic tile is provided, comprising the following steps: (b) mixing the components of the cured film of the bottom layer of the formulation amount to obtain the bottom layer slurry → mixing the bottom layer Apply the slurry to the surface of the unglazed tile → dry → the bottom cured film; (c) mix the components of the formula amount of the surface cured film evenly to obtain the surface layer slurry → apply the surface layer slurry to the bottom cured film Surface→dry→surface cured film.

[0090] The above preparation method is scientific and simple, suitable for industrial production, and has low production cost. The prepared self-cleaning ceramic tile not only has good self-cleaning ability, but also has good chemical corrosion resistance, good weather resistance, good stability and low cost. It is suitable for building kitchens, bathrooms, and self-cleaning exte...

Abstract

The invention relates to the field of a ceramic tile and particularly provides a self-cleaning ceramic tile and a preparation method thereof. The self-cleaning ceramic tile mainly comprises an unglazed tile, a bottom-layer immobilizing membrane and a surface-layer immobilizing membrane; the surface of the unglazed tile is coated with the bottom-layer immobilizing membrane and the surface-layer immobilizing membrane sequentially; each of the bottom-layer immobilizing membrane and the surface-layer immobilizing membrane consists of specific components with specific content; tiny pores exist on the surface of the unglazed tile, so that attachment of the bottom-layer immobilizing membrane is facilitated; the bottom-layer immobilizing membrane has strong adhesive force, is not liable to remove,has high extensibility, elastoplasticity, anti-cracking property, anti-permeability and weather resistance, and has high bondability with the unglazed tile and the surface-layer immobilizing membrane; the surface-layer immobilizing membrane can significantly improve the self-cleaning ability of the surface of the ceramic tile, and has high bondability with the bottom-layer immobilizing membrane and high weather resistance. In the self-cleaning ceramic tile, the unglazed tile, the bottom-layer immobilizing membrane and the surface-layer immobilizing membrane cooperate with one another to forma whole body, and the advantages of high self-cleaning ability, high chemical corrosion resistance, weather resistance, high stability and low cost are achieved.

Description

technical field [0001] The invention relates to the field of ceramic tiles, in particular to a self-cleaning ceramic tile and a preparation method thereof. Background technique [0002] my country is a large ceramic production and export country, and the output of building and sanitary ceramics ranks first in the world for many years. With the gradual development of science and technology and the improvement of people's living standards, people's awareness of health and environmental protection is also increasing. For this reason, people have put forward higher requirements for the performance of traditional architectural sanitary ceramic products, which are mainly reflected in the environmental protection, anti-fouling, self-cleaning and easy-cleaning properties of ceramic products, as well as more health care functions. [0003] Most of the self-cleaning ceramic products currently on the market are glazed and bright products with high water absorption. The basic process i...
