| abstract |
The invention relates to a fireproof and explosion-proof coating, which belongs to the technical field of architectural coatings, and comprises component A and component B with a weight ratio of 45-51:10-15, and component A includes polyurea prepolymer in parts by weight 50-60 parts, 5-10 parts of polyurethane gel and 10-15 parts of flame retardant, component B includes 20-30 parts by weight of diamine chain extender, 3-8 parts of nanoparticles and 25 parts of solvent ~35 servings. It has good fire resistance and freeze-thaw cycle resistance, so that the insulation board coated with this coating not only retains the light weight and heat preservation characteristics of the insulation board, but also has high compressive strength and good heat insulation Performance and excellent flame retardant and anti-knock performance. |
