Problems solved by technology

However, so far, although there are many reports on photocatalytic materials, there is no report on the application of photocatalytic materials
ZrP 2 o 7 It is a new type of photocatalytic material. There are few domestic research reports and only a small amount of international reports [Abdollah Javidan a, Abolfazl Ziarati, Javad Safaei-Ghomi. Simultaneous sonication assistance for the synthesis of tetrahydropyridines and its efficient catalyst ZrP 2 o 7 nanoparticles, Ultrasonics Sonochemistry, 21(2014) 1150-1154], and there is no report on preparing it as a glaze with photocatalytic function

Abstract

The invention relates to a photocatalytic function ZrP2O7 microcrystalline opaque glaze composition and a preparation method thereof. The microcrystalline opaque glaze composition includes the following components by mass percentage: 86-90% of powder A, 6-8% of ZrP2O7 and 4-6% of kaolin. Specifically, the powder A comprises, by weight, 12-16% of SiO2, 2-4% of Al2O3, 51-55% of P2O5, 2-4% of MgO, 8-10% of Li2O, 8-10% of Na2O and 8-10% of K2O. According to the invention, ZrP2O7 is introduced into the preparation of glaze for the first time, the obtained glaze layer has good opacifying decorative effect, but also has excellent performance of photocatalytic degradation of toxic gas.

Description

technical field [0001] The invention belongs to the technical field of ceramic materials, and relates to a method for preparing a glaze on the surface of building and sanitary ceramics, in particular to a ZrP with photocatalytic function 2 o 7 The invention discloses a method for preparing a microcrystalline opaque ceramic glaze. The surface of the glaze prepared by the method has an excellent photocatalytic degradation function, and at the same time has a good opacifying decorative effect and strong covering ability. And under the condition of sunlight, it can effectively decompose toxic gases in the air such as formaldehyde and NO x , benzene, etc., which are of great significance to the purification of the home environment. Background technique [0002] In the decoration process of buildings or people's indoor and outdoor, the toxic organic substances or gases released by various chemical products after decoration are still difficult to avoid at present, which has a gre...
