Problems solved by technology

[0003] Traditional solvent-based fireproof materials use a large amount of organic solvents in the preparation and construction, polluting the environment, endangering the health of operators and increasing costs
Compared with solvent-based fire retardant coatings, water-based fire retardant coatings have the characteristics of green and environmental protection, which meet the development requirements of environmentally friendly coatings, but water-based fire retardant coatings use water as the dispersion medium, and have the disadvantages of low bonding strength and poor water resistance. It is easy to fall off after a long time, so that it loses its fireproof effect and limits the application of water-based coatings

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-resistant and fire-resistant coating. Background technique [0002] Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. It is flame retardant or non-combustible Properties, so that the protected substrate is not in direct contact with the air, delaying the ignition of objects and reducing the speed of burning, improving the fire resistance of materials, slowing down the speed of flame spread, or preventing burning within a certain period of time. [0003] Traditional solvent-based fireproof materials use a large amount of organic solvents in the preparation and construction, polluting the environment, endangering the health of operators and increasing costs. Compared with s...
