Fireproof wind-sand-resistant paint for desert environment wood ancient building and preparation method of fireproof wind-sand-resistant paint

The invention provides fireproof wind-sand-resistant paint for a desert environment wood ancient building and a preparation method of the fireproof wind-sand-resistant paint. The paint comprises a component A and a component B, wherein the mass ratio of the component A to the component B is 1:2; the component A is prepared by adopting the following ingredients in parts by weight: 90 to 120 parts of acrylic polyurethane aqueous dispersion, 0.5 to 1.5 parts of a thickening agent and 5 to 20 parts of deionized water; the component B is prepared from the following ingredients in parts by weight: 2 to 8 parts of PMA, 0.5 to 5 parts of a dispersion agent, 0.2 to 0.8 part of a defoaming agent, 10 to 30 parts of deionized water, 10 to 40 parts of superfine talcum powder, 10 to 40 parts of kaolin, 10 to 30 parts of iron oxide red and 0.8 to 1.2 part of dimethyl methyl phosphonate. The combination force between the prepared paint and an iron tower foundation body is strong, and the prepared paint is environmentally friendly, has wind-sand impact resisting property and can meet the protection requirement of the desert environment wood ancient building. The paint is simple to produce and good in construction performance and does not need high-temperature curing and is rapid to dry at room temperature.
