Abstract

The invention discloses an interior wall inorganic coating prepared from an organic-inorganic composite emulsion and a preparation method of the interior wall inorganic coating. Comprising the following components in percentage by weight: 18 to 37 percent of water, 0.2 to 1.0 percent of powdery thickening agent, 0.1 to 0.3 percent of sterilizing agent, 0.4 to 0.8 percent of dispersing agent, 0.1 to 0.4 percent of wetting agent, 0.2 to 0.7 percent of defoaming agent, 0.1 to 0.3 percent of pH value regulator, 5 to 20 percent of titanium dioxide, 3 to 10 percent of kaolin, 22.4 to 35 percent of functional filler and 10 to 35 percent of organic-inorganic composite emulsion. The coating does not contain VOC (Volatile Organic Compounds) and harmful substances specified in the GB18582-2020 standard, has the characteristics of non-combustibility, self-breathing, antibiosis and mildew resistance, has good stability, and is convenient to store at normal temperature; and the quality is easy to control, and a lot of time is not needed to carry out intermiscibility and compatibility tests of the potassium silicate and the organic emulsion, so that time and labor are saved.

Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to an inorganic coating for interior walls prepared from an organic-inorganic composite emulsion and a preparation method thereof. Background technique

[0002] In the field of coatings, compared with the more commonly used water-based organic coatings, water-based inorganic coatings are used in subway tunnels, schools, hospitals, basements because of their more environmentally friendly, non-combustible, self-breathing, antibacterial and anti-mildew properties. It is used in important places with special requirements.

[0003] At present, most of the production technology of inorganic coatings is made of potassium silicate, lithium silicate, silica sol or one of these materials and organic emulsions as adhesive materials, and adding appropriate amount of pigments and fillers, water-based coating additives. However, the disadvantage of this formula is that the inorganic adhesive ma...
