Problems solved by technology

[0005] In the formula design of fire retardant coatings, flame retardants containing halogens are often added. This type of fire retardant coating has a relatively good flame retardant effect, but it will release a lot of smoke and hydrogen halide gas during the combustion process, which is easy to suffocate people. , a large number of fire analyzes have show

Abstract

The present invention relates to one kind of super thin no-halogen less-smoke fireproof organic-inorganic composite paint and its preparation process. The composite paint is compounded with heat resistant organic and inorganic nanometer hybridized resin, organic resin, heat resistant pigment, heat resistant filler, carbon forming agent, foaming agent, catalyst, assistant, etc. In case of fire, the components of the paint synergy to swell, foam, isolate oxygen, delay heat transfer and inhibit fire spread. The fireproof paint may be used to form coating of controllable thickness in 0.2-2 mm, has fire resisting limit of 30-200 min, excellent heat resisting performance, excellent fire retarding performance, high fireproof performance, high anticorrosion performance and other advantages.

Description

technical field [0001] The invention relates to the fields of chemical industry, fire protection and anticorrosion, and relates to a halogen-free, low-smoke, ultra-thin organic-inorganic composite fireproof coating and a preparation method thereof. Background technique [0002] There are many types of fire-resistant coatings for steel structures, which can be divided into water-based, solvent-based and powder-based according to their material forms; organic-type, inorganic-type and organic-inorganic-type according to the type of resin; according to the fire prevention mechanism, they can be Divided into heat insulation type, expansion type and non-expansion type, according to the thickness of the coating, it is divided into thick type, thin type and ultra-thin type. The ultra-thin steel structure fireproof coating is mainly composed of base resin, char-forming agent, foaming agent, catalyst, etc. Isolate oxygen and have good heat insulation performance, which can delay the ...
