Problems solved by technology

The research on fire retardant coatings in our country started late. One way of current fire retardant coatings is to use flame retardant organic polymers as base materials. However, organic polymers in coatings are toxic to the human body and harmful to the environment. Another method is to add flame retardants to the coatings, representative halogen-based, phosphorus-based fire-resistant coatings, but some bromine-based fire-resistant coatings in the halogen series are controversial due to environmental protection issues

Abstract

The invention provides an inorganic coating. The inorganic coating is prepared from the following raw materials in parts by weight: 15 to 25 parts of deionized water, 25 to 35 parts of composite silicate aqueous solution, 3 to 5 parts of mixed zeolite silicon powder and 15 to 30 parts of fillers, wherein the composite silicate aqueous solution is prepared by mixing a lithium silicate aqueous solution, a sodium silicate aqueous solution and methane-siliconic acid emulsion in a ratio by mass part of (8 to 10): (3 to 5): 1; and the mixed zeolite silicon powder is prepared by mixing zeolite powder, aluminum silicate fibers and silica aerogel in a ratio by mass part of (2 to 4): (5 to 7): 1. The invention also provides a method for preparing the inorganic coating. The method comprises the following steps: first preparing a coating basic mixed solution; then adding the composite silicate aqueous solution into the coating basic mixed solution, and mixing and grinding to obtain a coating finished product. The inorganic coating is high in fire rating, good in weather resistance, environment-friendly, non-toxic, simple in preparation process and low in cost.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an inorganic coating and a preparation method thereof. Background technique [0002] Building fire prevention is an important field of fire science and technology, and fireproof coating is an important part of fireproof building materials. The fire retardant paint is coated on the surface of the object. When a fire occurs, the coating film of the fire retardant paint itself is flammable or non-combustible, which has a good protective effect on the substrate and wins time for fire extinguishing and personnel evacuation. Therefore, its research and The application has attracted great attention from all over the world. The research on fire retardant coatings in our country started late. One way of current fire retardant coatings is to use flame retardant organic polymers as base materials. However, the organic polymers in the coatings are toxic to the human body and harmful to the...
