Problems solved by technology

[0002] At present, there are two types of fire retardant coatings in the world: one is non-foaming fire retardant coatings, which have strong fire resistance and water resistance, but poor heat insulation and low fire resistance.
The other type is foaming fireproof coating, especially when it encounters a fire, it can form a heat insulation layer with a honeycomb microbubble structure, which has good heat insulation performance. This type of coating usually uses organic polymers as film-forming materials. Excellent fire resistance and good fire resistance, but the foam insulation layer has low mechanical strength and is easy to fall, resulting in reduced or invalid fire resistance. In addition, the cost is high and the decoration is not ideal

The present invention has excellent fireproof performance, can bear the effect of flame, and has fireproof foamed layer with high heat isolating performance, high mechanical strength, less chap and falling out, good decoration property, low cost and other advantages.

Description

Technical field: [0001] The invention relates to a novel composite fireproof paint, which belongs to the composite paint of inorganic macromolecule and organic macromolecule film-forming materials. Background technique: [0002] At present, there are two types of fire retardant coatings in the world: one is non-foaming fire retardant coatings. Although they have strong fire resistance and water resistance, they have poor heat insulation and low fire resistance. The other type is foaming fireproof coating, especially when it encounters a fire, it can form a heat insulation layer with a honeycomb microbubble structure, which has good heat insulation performance. This type of coating usually uses organic polymers as film-forming materials. Excellent fire resistance and good fire resistance, but the foam insulation layer has low mechanical strength and is easy to fall, resulting in reduced or invalid fire resistance. In addition, the cost is high and the decoration is not ideal....
