High-temperature-resistant building anticorrosive paint and production process thereof

The invention relates to the technical field of building coatings, and particularly discloses a high-temperature-resistant building anticorrosive coating and a production process thereof. The high-temperature-resistant building anticorrosive paint is prepared from the following raw materials in parts by weight: 10 to 15 parts of ethyl silicate, 5 to 10 parts of polyvinyl butyral, 2 to 4 parts of polybasic acid, 10 to 20 parts of acrylic resin, 40 to 50 parts of silica sol, 10 to 15 parts of high-temperature-resistant filler, 0.2 to 0.5 part of thickening agent and 5 to 8 parts of modified glass fiber, the modified glass fiber is obtained by modifying with polydopamine; the preparation method comprises the following steps: uniformly stirring and mixing silica sol, ethyl silicate, polyvinyl butyral and acrylic resin to obtain a mixed solution; adding the polybasic acid, the high-temperature-resistant filler and the modified glass fiber into the mixed solution, uniformly stirring and mixing, and adding the thick
