Outdoor thick steel structure fire-retardant coating
The invention relates to an outdoor thick steel structure fire-retardant coating and belongs to the field of building materials. The fire-retardant coating is prepared by mixing the following raw materials in percentage by weight: 10-20% of natural sepiolite fabric, 4-6% of light calcium carbonate, 20-30% of hole-closed perlite, 1-1.4% of high-strength water-resistant rubber powder, 1.6-2% of a hydrophobic agent, 40-44% of Portland cement and 8.0-12% of refractory cement. Since the fire-retardant coating is prepared by mixing natural sepiolite fabric, hole-closed perlite, light calcium carbonate and high-strength water-resistant rubber powder, polymer long chains in high-strength water-resistant rubber powder form continuous network structures which are interspersed one another, the bonding strength of the final product is significantly improved, and meanwhile, the water resistance, crack resistance, weather resistance and impact resistance of the cement-based products can also be improved and the fire-retardant coating has good chemical resistance and water resistance and hardly falls off.
