Photocatalytic negative ion ceramic tile containing various dielectric substances, and preparation process thereof

Abstract

The invention relates to the technical field of ceramics and functional decorative materials, and especially relates to a photocatalytic negative ion ceramic tile containing various dielectric substances, and a preparation process thereof. The ceramic tile comprises a ceramic tile blank, ground glaze and surface glaze, the ground glaze is prepared from niobium oxide, nanometer magnesium oxide, strontium carbonate, lanthanum oxide and potassium sodium niobate; the surface glaze comprise a composite photocatalytic material, and the composite photocatalytic material comprises zinc oxide and tin oxide; and the weight part ratio of zinc oxide to tin oxide is (2-3): 1. The dielectric substances contained in the ceramic tile can form a weak electric field, the weak electric field has excitationand reinforcement effects on substances with photocatalysis functions, such as zinc oxide and tin oxide. The invention further provides the preparation process of the photocatalytic negative ion ceramic tile containing the various dielectric substances. The prepared ceramic tile has a good formaldehyde removal effect, the formaldehyde purification efficiency can meet the class II requirements of the JC / T1074-2008 standard, and the photocatalytic negative ion ceramic tile can be safely used in various places without limitation.

Description

technical field [0001] The invention relates to the technical field of ceramics and functional decorative materials, in particular to a photocatalytic negative ion ceramic tile containing various dielectric substances and a preparation process thereof. Background technique [0002] With the development of industry, air pollution has become more and more serious, and the air contains various substances that are harmful to the human body, so air purification has attracted more and more attention. [0003] In recent years, many interior decoration materials for purifying air have emerged in domestic and foreign markets, such as negative ion paint, negative ion sheet, negative ion ceramic tile, photocatalytic coating and photocatalytic ceramic tile. [0004] There are two types of negative ion bricks on the market, one is the introduction of rare earth composite salts into the ceramic glaze layer; the other is that the surface of the ceramic brick is coated with a photocatalyst ...

AI Technical Summary

Problems solved by technology

[0005] The negative ion tiles currently produced on the market have low negative ion induction or high radioactivity, and the air purification effect is poor.
