Problems solved by technology

The advantage of this method is that it does not require a high-temperature roasting process, reduces the preparation cost and can keep TiO 2 The good photocatalytic performance of the powder is not destroyed, and the selection of the carrier can be extended to the surface of organic materials that are not resistant to high temperature, but the disadvantage is that the thickness of the coating prepared by this method is not easy to control

Embodiment Construction

[0034] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0035] Nano-TiO 2 The method that sol is coated on ceramic glaze, comprises the following steps:

[0036] Step 1: pickling of ceramic glaze; preparation of nano-TiO 2 sol, and thicken it;

[0037] Step 2: Nano TiO 2 The sol is coated on the ceramic glaze; the coating tool includes a glass water scraper and a dust-free cloth; the length of the glass water scraper is 10cm-60cm; the dust-free cloth is one to six layers, and is flatly wrapped on the glass Squeegee on;

[0038] Step 3: Nano TiO 2 The sol was naturally air-dried and solidified into nano-TiO 2 film, and then heat-treat the ceramic glaze.

[0039] Further, the nano-TiO 2The preparation method of the sol is: adding an anionic surfactant or a nonionic surfactant with a mass percentage of 0.1%-10% to the nano-TiO with a mass percentage...

Abstract

The invention relates to the technical field of nanometer coatings, and in particular relates to a method and tool for applying nanometer TiO2 sol onto a ceramic glaze surface and a generated coating. The method comprises the following steps: step 1: pickling the ceramic glaze surface; preparing the nanometer TiO2 sol, and conducting thickening; step 2: applying the nanometer TiO2 sol onto the ceramic glaze surface; step 3: naturally air-drying and curing the nanometer TiO2 sol into a nanometer TiO2 film, and then conducting heat treatment on the ceramic glaze surface. According to the invention, the traditional sol-gel method is improved to develop the method for applying the nanometer TiO2 sol onto the ceramic glaze surface; the method is simple in operation, does not need high-price equipment, and avoids high cost and high energy consumption. The invention further provides the nanometer TiO2 coating produced by the method, and the nanometer TiO2 coating is very thin. The invention further provides the tool for applying the nanometer TiO2 coating, and the tool has the advantages of simple structure, convenience in manufacturing and low cost.

Description

technical field [0001] The invention relates to the technical field of nano coatings, in particular to a method for coating nano TiO2 sols on ceramic glazes. Background technique [0002] In daily life, in order to keep the glass surface of the building exterior wall clean and attractive in appearance, people often use various cleaning agents such as surfactants and descaling agents to repeatedly scrub the stained surface. Its main cleaning principle is the chemical decontamination ability of the detergent and the mechanical detergency of the cleaning brush. This kind of cleaning work is not only not easy, but the surface after cleaning will be polluted in a short time, and the cleaning frequency is high, resulting in the use of a large amount of surfactants, which brings great pressure to the human environment. [0003] There are many methods for the preparation of self-cleaning superhydrophilic coatings: [0004] The sol-gel method is the production method of the self-cl...
