Antipollution film used for ceramic opaque glaze/semi-opaque glaze and preparation technology thereof

Abstract

The invention relates to an antipollution film used for a ceramic opaque glaze / semi-opaque glaze and a preparation technology thereof. The preparation technology comprises the following steps of: salt solution preparation: adding 10-40 parts by weight of alkali metal ion compound and / or alkaline earth metal ion compound in total into 60-90 parts by weight of water and stirring uniformly to form the salt solution; spraying: spraying the salt solution on a water receiving surface of the inner wall of a cavity of a ceramic glazing blank device, wherein the ceramic glazing blank with the salt solution has a certain dryness so that a certain amount of solution can be absorbed; and sintering: sintering the glazing blank with the salt solution according to a normal sintering process. The preparation technology of the antipollution film can be compatible and linked with different ceramic production processes and has no specific requirement on a formula of blank glaze, and the original production process is not greatly changed; and the preparation technology can give an antipollution easy-cleaning function to the ceramic opaque glaze / semi-opaque glaze and also can improve brightness and whiteness of the glaze and improve aesthetics of the glaze, and cost is low.

Description

technical field [0001] The invention relates to an antifouling film layer and a preparation process thereof, in particular to an antifouling film layer used for ceramic opacity glaze / semi-opacity glaze and a preparation process thereof. Background technique [0002] Opacity glaze (commonly known as cover glaze or white glaze) is a kind of glaze layer material with strong hiding power for porcelain body. Because it can greatly improve the whiteness of ceramic products and has a good decorative effect on ceramic surface, it is widely used in ceramics. Ceramic sanitary ware, building materials tiles and enamel products have been widely used in fields such as. Semi-opacifying glaze (also known as translucent glaze) is a semi-transparent and semi-opacifying mixed glaze layer that introduces an appropriate amount of opacifying agent into the transparent glaze layer to cover the defects of the porcelain body and improve the whiteness of the glaze. With the increasing shortage of h...

Problems solved by technology

[0005] In view of the limitations of the existing ceramic anti-fouling technology, the present invention provides a set of brand-new anti-fouling film layer for ceramic opacified glaze / semi-opacified glaze and its preparation process, so as to overcome the relatively aging time of anti-fouling existing in the prior art. Short-term, poor anti-fouling effect, high production cost and cumbersome production process procedures, etc.
