Negative ion ceramic tile and preparation method thereof

Abstract

The invention provides a negative ion ceramic tile. The negative ion ceramic tile comprises a green body layer and a glaze layer, the glaze layer is prepared from the following raw materials in partsby weight: 3-5 parts of negative ion powder, 30-50 parts of attapulgite, 20-40 parts of porous diatomite, 8-15 parts of microcrystalline glass, 20-30 parts of titanium dioxide, 5-10 parts of zinc oxide, 2-3 parts of modified phenolic resin and 1-5 parts of a titanate coupling agent; the preparation method of the negative ion powder comprises the following steps: mixing tourmaline powder, nano cuprous oxide, stannic chloride and nano zinc oxide, heating at 200 DEG C for 1 hour, heating at 350 DEG C for 1 hour to obtain a primary sinter, adding iron pentahydrate, LiTFSi and silicone, uniformly mixing, sintering at 500 DEG C in a nitrogen atmosphere, and pulverizing to 200 meshes, wherein the modified phenolic resin is modified by adding 0.5% of 1, 3-dimethylimidazole dimethyl phosphate salt.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an anion ceramic brick and a preparation method thereof. Background technique [0002] With the development of urbanization, people pay more and more attention to the air quality of cities. Because of its remarkable biological effect, negative air ions can not only improve air quality, but also have a certain health care effect on the human body. Therefore, increasing the content of negative ions in the air has become an important way for people to improve air quality. [0003] Adding negative ion materials and the like to building materials to enable building materials to generate negative ions is an effective means of increasing negative ions in the air. Among them, ceramic bricks are used as a large amount of building materials, and adding negative ion materials to ceramic bricks to prepare ceramic bricks that can generate negative ions has become a common method...

AI Technical Summary

Problems solved by technology

However, the current preparation of ceramic tiles that can generate negative ions is usually to directly add negative ion materials to the body of the ceramic tiles, and the consumption of negative ion materials is large and the cost is relatively high.
