Oil stain self-purification tile and method for manufacturing same

Abstract

The invention relates to an oil pollution self-cleaning ceramic tile and a manufacturing method thereof; the oil pollution self-cleaning ceramic tile comprises a ceramic tile substrate, and a layer of oil pollution self-cleaning layer is fired on the positive surface of the ceramic tile substrate, the average thickness of the oil pollution self-cleaning layer is 0.5 to 1.5mm, and the manufacturing method comprises the steps of manufacturing the ceramic tile substrate, steps of manufacturing oil pollution self-cleaning layer slurry and steps of firing ceramic tiles. The oil pollution self-cleaning ceramic tile can realize the efficient decomposition and self-cleaning of oil pollutions which are adhered on the surface of the ceramic tiles, thus guaranteeing the neatness and health of kitchen walls effectively; the oil pollution self-cleaning ceramic tile without manual cleaning which can reduce the working strength of family cleaning greatly is beneficial to improve the life environment and increase the life quality; the oil pollution self-cleaning ceramic tile is simple in manufacturing technique, easy in manufacturing the oil pollution self-cleaning layer slurry, low in cost and considerable in economic benefit. The oil pollution self-cleaning ceramic tile and the manufacturing method of the invention provide a cleaner and more environmental new product and a preparation method for the home building material field.

Description

technical field

[0001] The invention belongs to the field of building materials, in particular to an oil-stained self-cleaning ceramic tile and a manufacturing method thereof. Background technique

[0002] At present, ceramic tiles are generally pasted on the walls of home kitchens to prevent the walls from being dirty and to beautify the decoration. However, the kitchen has been in an oily environment for a long time, and oil stains will inevitably adhere to the surface. This kind of oil stains is an extremely difficult to remove dirt. Under incomplete oxidation, a polymerization reaction occurs, and finally a substance with a large molecular weight and a high boiling point is formed. This substance is insoluble in water and difficult to remove. Over time, it will affect the cleanliness and sanitation of the kitchen. Although the existing glazed tiles have certain antifouling and waterproof capabilities, once oil stains adhere to the surface, they still need to be cleaned...
