Problems solved by technology

First, during the high-temperature firing process of ceramic tiles, the photocatalytic activity of titanium dioxide photocatalyst will be significantly reduced due to the growth of titanium dioxide photocatalyst particles and crystal transformation, and at the same time, the photocatalytic activity of titanium dioxide will also be reduced due to the coverage of titanium dioxide by glaze; It is the addition of functional components such as titanium dioxide to the glaze, which will affect the smoothness of the uranium surface of the fired tiles and increase the technical difficulty of uranium surface firing

Abstract

The invention relates to an antibacterial, mildewproof, self-cleaning, air cleaning and environment-friendly spray coating liquid, which comprises the following raw materials in percentage by weight: 0.5 to 20 percent of modified adsorbent, 0.1 to 10 percent of nano photocatalyst, 0.1 to 10 percent of binding and film forming agent, 0.01 to 5 percent of dispersant, and the balance of deionized water. The preparation method comprises that: photocatalyst powder is subjected to acid soluble treatment by inorganic strong acid and prepared into sol; adsorbent is immerged in a soluble salt mixture solution of antibacterial and mildewproof ions, subjected to ion exchange treatment and prepared into the modified adsorbent which is mixed with the binding and film forming agent and the dispersant; two types of solutions are mixed and a spray coating liquid precursor is obtained; and the antibacterial, mildewproof, self-cleaning, air cleaning and environment-friendly spray coating liquid is obtained after distributed processing and filtration. The antibacterial, mildewproof, self-cleaning, air cleaning and environment-friendly spray coating liquid can be applied to antibacterial, mildewproof and self-cleaning treatment of buildings or articles. The antibacterial, mildewproof, self-cleaning, air cleaning and environment-friendly spray coating liquid realizes synergetic and reinforced combination of three functions through the composition of multi-functional compositions, and the preparation method is simple and environment-friendly, has good industrial benefit and can realize industrialized production.

Description

technical field [0001] The invention belongs to the field of building composite spraying liquid and its preparation and application, in particular to an antibacterial, anti-mildew, self-cleaning, air-purifying and environment-friendly spraying liquid, as well as its preparation and application. Background technique [0002] People spend about 80% of their time indoors. The use of a large number of chemical building materials and daily chemicals will continuously emit various air pollutants indoors. The space is becoming more and more closed, which makes it impossible to improve the indoor air pollution through natural ventilation. What's more, due to the pollution of the atmosphere by automobile exhaust and industrial waste gas, the city has no clean outdoor air to change. Therefore, in order to To improve the quality of indoor air where people live, commodities such as air purifiers and air fresheners have been valued by consumers. [0003] Various environmentally friendly...
