Abstract
This invention discloses a modified polymer cement-based room-temperature foamed fire-retardant coating and its preparation method, relating to the field of fire-retardant coating technology. The modified polymer cement-based room-temperature foamed fire-retardant coating comprises component A and component B. Component A comprises the following raw materials in parts by weight: 15-20 parts cement, 10-12 parts calcium carbonate, 0.3-0.9 parts nano-titanium dioxide, 30-35 parts polyurethane emulsion, 1-2 parts crosslinking agent, 8-12 parts flame retardant, 1-3 parts foaming agent, 0.5-1.5 parts dispersant, and 10-20 parts deionized water. Component B comprises the following raw materials in parts by weight: 20-25 parts curing agent, 0.1-0.5 parts organic zinc catalyst, and 0.5-1.2 parts foam stabilizer. The modified polymer cement-based room-temperature foamed fire-retardant coating prepared by this invention exhibits excellent fire-retardant performance, bonding strength, and compressive strength.
