Waterproof efficient intumescent fire retardant coating

Abstract

The invention discloses a waterproof efficient intumescent fire retardant coating. The waterproof efficient intumescent fire retardant coating is prepared from, by mass, 40-75 parts of inrumescent flame retardant, 8-15 parts of film formers, 7-10 parts of pigment, 9-15 of fillers, 0-5 parts of adjuvant, and 10-30 parts of water. After being formed into film, the waterproof efficient intumescent fire retardant coating is better in water resistance, long in service life, solid in densification of formed carbon layer, good in heat insulation effect, and long in fireproofing time.

Description

technical field [0001] The invention relates to a water-based high-efficiency expansion type fireproof coating. Background technique [0002] Intumescent fire retardant coating is a kind of functional coating, which can form a layer of dense carbon layer on the coated surface that is dozens or even hundreds of times the thickness of the paint film in the event of a fire, effectively protecting the substrate from heat and oxygen. It has the advantages of low density, easy construction, low cost, and can be used in various complex shapes and surfaces. It is widely used in fire protection in many places such as steel structures, cables, ceilings, walls, tunnels, and aircraft. [0003] Due to the development of environmental protection and new technology and new material technology, the use of new water-soluble fireproof coatings has become a trend. Not only its physical and mechanical properties are close to organic solvent-based fireproof coatings, but also its toxicity and sa...

Problems solved by technology

Small molecules in ammonium polyphosphate will not only affect its water resistance, but also accelerate the degradation of ammonium polyphosphate, resulting in more small molecular acids and ammonium salts, which will cause the coating to swell and foam when it meets water during use.
