Magnesium phosphate cement-based steel structure anti-corrosion fireproof coating

The invention discloses a magnesium phosphate cement-based steel structure anti-corrosion fireproof coating which is prepared from dead burned magnesium oxide, dihydric phosphate, zinc phosphate, polyphosphate, redispersible latex powder, silane-based powder, polyvinyl alcohol, borax and zinc borate as anti-corrosion bonding components and expanded vermiculite, expanded perlite, hollow floating beads and sepiolite as flame-retardant heat-insulating components. The anticorrosive fireproof coating provided by the invention not only meets the requirements of related technical indexes, but also has the characteristics of good cohesiveness, strong corrosion resistance and good corrosion resistance, and is environment-friendly and pollution-free. 本发明公开了一种磷酸镁水泥基钢结构防腐型防火涂料，其是以重烧氧化镁、磷酸二氢盐、磷酸锌、聚磷酸盐、可再分散乳胶粉、硅烷基粉末、聚乙烯醇、硼砂、硼酸锌为防腐粘结组分，膨胀蛭石、膨胀珍珠岩、空心漂珠、海泡石为阻燃隔热组分构成。本发明所提供的防腐型防火涂料不仅满足相关技术指标的要求，还具有粘结性好、抗锈蚀能力强，具备良好防腐蚀能力的特点，且环保无污染。
