Abstract
The invention discloses an inorganic mineral environment-friendly fire-retardant coating and a preparation method thereof. The inorganic mineral environment-friendly fire-retardant coating is prepared from, by weight, 15-35 parts of a potassium silicate solution, 1-1.5 parts of a dispersing agent, 1-2.5 parts of a thickening agent, 1-3 parts of dimethyl silicone, 3-9 parts of emulsion, 1-10 parts of titanium dioxide, 1-9 parts of ferric oxide, 1-9 parts of sepiolite, 1-6 parts of zinc oxide, 1-8 parts of tourmaline, 1-4 parts of kaolin, 0.5-2.5 parts of silica sol and 10-50 parts of water. According to the inorganic mineral environment-friendly fire-retardant coating and the preparation method thereof, the variety and using amount of the thickening agent and the dispersing agent which are suitable for an exterior wall coating are preferably selected through the reasonable proportion, the water resistance, the scratch resistance, the stain resistance, the breathability and the weather resistance of a coating film are improved, peeling and color fading are avoided, and meanwhile the advantages of being resistant to fire and flame, capable of achieving sterilization without generating mildew stain and environmentally friendly are achieved; in addition, construction is easy and convenient, and the environmental adaptability is better.
Description
technical field [0001] The invention relates to the technical field of coatings, in particular to an inorganic mineral environmental protection fireproof coating and a preparation method thereof. Background technique [0002] Paint is a material that can be well bonded to the base material and form a complete and tough protective film on the surface of an object, called a paint. Paint and paint are the same concept. Paint is a customary name that people have used for a long time. After it was introduced into my country, it has been used in the construction industry. The role of coatings can be summarized into three aspects: protection, decoration, and special functions. The general composition of coatings: including film-forming substances, pigments and fillers, solvents, and additives. [0003] Architectural coatings have the functions of decoration, protection and habitability improvement. The proportions of various functions vary depending on the purpose of use. The ...
