Problems solved by technology

[0003] Existing coatings will add flame retardants during the preparation process in order to make the coatings flame retardant. The commonly used flame retardants are organophosphorus flame retardants, but organophosphorus flame retardants will Precipitation occurs, causing the flame retardant to separate from the coating, which in turn causes the coating to lose its flame retardancy

Abstract

The invention discloses a flame-retardant coating for interior decoration and a preparation method thereof. The flame-retardant coating comprises the following raw materials in parts by weight: 80-100parts of acrylic acid, 1-1.5 parts of a dispersing agent, 0.5-0.8 part of a defoaming agent, 3-3.5 parts of titanium dioxide, 12-15 parts of talcum powder, 10-13 parts of kaolin powder and 10-13 parts of mica powder. In the process of preparing the flame-retardant coating, a flame retardant is prepared, and the flame retardant is a phosphorus flame retardant. When the coating is combusted, the flame retardant is heated and decomposed into phosphorus oxyacid, the phosphorus oxyacid can catalyze a hydroxyl-containing compound to dehydrate into carbon, the mass loss speed of the material and thegeneration amount of combustibles are reduced; the flame retardant molecules are hydroxymethylated substances; when the flame-retardant coating is mixed with acrylic acid to prepare an acrylic emulsion, the acrylic emulsion and an ammonium ceric nitrate aqueous solution form a reduction system, so that free radicals for initiating polymerization of alkene monomers are formed, flame retardant molecules and acrylic acid are subjected to graft polymerization, the flame retardant cannot be separated out of the coating when the flame-retardant coating is used, and the flame retardance of the coating is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of paint preparation, and in particular relates to a flame-retardant paint for interior decoration and a preparation method thereof. Background technique [0002] Paint is a substance that can form a complete film on the surface of an object and can be firmly bonded to the surface of the object. Early paints are mainly made of natural animal oils, vegetable oils and natural resins, so paints are also called paints. Since the 1950s, the rapid development of the world's petrochemical industry and polymer synthesis industry has provided a good material basis for the development of the paint industry. Therefore, in addition to a small amount of natural resin and oil, the current paint is mainly made of synthetic resin. for film-forming substances. [0003] Existing coatings will add flame retardants in the preparation process in order to make the coatings flame retardant. Commonly used flame retardants are orga...
