Abstract

The invention discloses a composition for forming a non-combustible coating. The composition comprises the following raw materials in parts by weight: 50.4-64.8 parts of adhering resin, 19.6-25.2 parts of water, 6-26 parts of expanded graphite, and 2-4 parts of kerosene, wherein the adhering resin is selected from one or a plurality of watercraft acrylic resin and aqueous ethylene resin. The composition aims at forming the non-combustible coating with outstanding long-term storing performance; the dense non-combustible coating of resin and expanded graphite composite material is formed on thesurface of a substrate, so that the non-combustible coating is outstanding in non-combustible performance, and outstanding in water resistance, heat resistance and mechanical strength.

Description

technical field [0001] The present invention relates to a composition for forming a non-combustible coating. Background technique [0002] Since buildings tend to become larger and taller, construction fires often lead to large-scale accidents. This is why fire protection standards tend to be strengthened, as are non-combustibility and fire protection standards for building finishing materials and other facilities. [0003] Fire retardant paint is to coat a layer of paint on the surface of flammable materials such as wood, sponge foam, plastic, etc. to prevent fire or delay the time of fire. There are two types of fireproof coatings, one is based on fireproof materials, and the other is foamed after heating, forming a shielding layer between fireproof materials to shield flames and delay heat conduction. [0004] The former is prepared by adding various pigments and non-combustible powders to fireproof materials, including fireproof or noncombustible resins, chlorine compo...
