[0003] After searching, it is found that the prior art 201510960983.8 discloses a water-based latex paint for anti-graffiti healthy indoor coating and its preparation method. This technology achieves the effect of anti-graffiti by adding fluorine-containing polymers, but fluorine-containing substances are toxic substances, which are harmful to the human body. It will cause great harm and is not conducive to human health; moreover, fluorine-containing polymers are very difficult to degrade when discarded, causing great damage to the environment. Many countries are restricting the use of fluorine-containing compounds

Embodiment 1-3
[0049] Embodiments 1-3 respectively provide a water-based inorganic anti-graffiti ceramic coating for indoor walls, and the specific components are shown in Table 1.
[0050] Table 1
[0051]
[0052]
[0053] The preparation method of the coating that above-mentioned embodiment 1 of the present invention, embodiment 2, embodiment 3 provides is identical, comprises the preparation of primer coating and the preparation of surface coating;
[0054] (1) The preparation of the primer coating comprises:
[0055] Prepare materials by the components and weight percentages thereof of primer coating shown in above-mentioned table 1;

The invention discloses a water-based inorganic anti-graffiti ceramic coating for indoor walls and a preparation method thereof; the ceramic coating is a double-coat coating, which includes a primer coating and a top coating coating. Compared with the prior art, the advantages and effects of the present invention are: the main film-forming substance is inorganic, most of the solvent is deionized water, the VOC emission is extremely low, and it has the characteristics of safety, health and environmental protection; it overcomes the multi-component ceramic coating , the shortcoming that it needs to be matured before use, the primer and top coat of the invention are both one-component, can be used directly, and the construction is convenient and fast; it has anti-graffiti effect, and the water-based pen can be easily erased when writing and drawing on the wall; The layer has low surface tension, which can isolate outdoor moisture and prevent the wall from becoming damp and mildew.
Description
technical field [0001] The invention relates to the technical field of indoor environmental protection coatings, in particular to a water-based inorganic anti-graffiti ceramic coating for indoor walls and a preparation method thereof. Background technique [0002] At present, the wall paint for home interior decoration on the market is latex paint, and its film-forming substance is mainly styrene-acrylic emulsion, and there are a small amount of vinegar-acrylic and pure acrylic emulsion. This kind of paint can only play a simple decorative role. Since the film-forming substances of latex paint are organic substances, more or less organic solvents will be added in the process from the synthesis of raw materials to the production and painting of paint, which will cause some harm to the environment and human body. With the development of the economy, people have higher and higher requirements for home decoration. For the painting of the wall, it is not only limited to the smoot...
