Abstract

The invention provides an inorganic-silicate fire-retardant coating which comprises M2O.nSiO2 and an inorganic solvent, wherein n is within the range from 2.8 to 5.5, and M2O is one of Na2O, K2O, or Li2O. Because the inorganic-silicate fire-retardant coating does not contain any organic substance, a coated substrate can be protect from going mouldy and aging. In addition, the invention also provides a method for preparing the inorganic-silicate fire-retardant coating, and the method comprises the steps: enabling the inorganic-silicate fire-retardant coating to be coated on the substrate; forming an inorganic-silicate fire-retardant protection layer. The inorganic-silicate fire-retardant protection layer can achieve the fireproof and flame retardant effects. Moreover, the inorganic-silicate fire-retardant protection layer can solve problem that a conventional organic fire-retardant protection layer generates toxic gas and dense smoke after heating because the inorganic-silicate fire-retardant protection layer does not contain any organic substance, thereby effectively reducing the severity of injuries caused by fire hazard.

Description

technical field [0001] The invention relates to an inorganic silicate fireproof coating, especially an inorganic silicate fireproof coating without organic substances. In addition, the present invention relates to a preparation method of an inorganic silicate fire protection layer. Background technique [0002] Therefore, how to develop a good fire-resistant coating and use this fire-resistant coating to protect the surface of buildings, thereby effectively reducing the speed of fire spread and the severity of casualties caused by fire, and even reducing the number of fires has become very important at present. topic. [0003] Common fire retardant coatings on the market are organic fire retardant coatings or organic / inorganic fire retardant coatings, most of which are based on organic binders (such as polyurethane, organosiloxane, epoxy resin, phenolic resin, etc.), and organic Additives such as flame retardants, organic dispersants, pigments, etc., use the oxides gene...
