Problems solved by technology

Therefore, flame-retardant coatings have become a research hotspot, but there are still some deficiencies in existing flame-retardant coatings. The existing technology of realizing flame-retardant substrates through the catalytic charring of coating films uses a dehydration catalyst with a high decomposition temperature. However, the low temperature activity is poor, and the flame retardant performance of the coating is not good.
Because when a fire occurs, the film-forming substance is often thermally decomposed before the dehydration catalyst, producing more flammable volatile organic compounds, affecting the formation and structure of the carbon layer, and thus affecting the protection of the substrate

Abstract

The invention discloses an aqueous flame-retardant coating and a preparation method thereof. The aqueous flame-retardant coating comprises following compositions: aqueous acrylic emulsion, amino resin, deionized water, nitrogen flame retardants, substrate lubricants, leveling agents, defoamers and catalysts. The preparation method of the aqueous flame-retardant coating comprises the following steps of: firstly adding the amino resin into the aqueous acrylic emulsion; then adding the substrate lubricants, the leveling agents, the nitrogen flame retardants, the defoamers and the catalysts in sequence; and stirring quickly to obtain the aqueous flame-retardant coating. The processing technology disclosed by the invention is simple, the composition ratio is rational, and the produced coating has a good flame-retardant effect, and can be widely applied to the places having fireproof demands, such as KTV (Karaoke Television) clubs, movie theaters and the like.

Description

technical field [0001] The invention relates to a water-based flame-retardant coating and a preparation method. Background technique [0002] At present, the amount of wood materials and paints used in interior decoration is increasing year by year. Due to the flammability and flammability of wood materials and some paints, there must be fire hazards. In recent years, due to the extensive use of decorative materials, such fires are on the rise. The preparation of new non-combustible and flame-retardant decorative materials has been highly valued by relevant state departments. Therefore, flame-retardant coatings have become a research hotspot, but there are still some deficiencies in existing flame-retardant coatings. The existing technology of realizing flame-retardant substrates through the catalytic charring of coating films uses a dehydration catalyst with a relatively high decomposition temperature. However, the low-temperature activity is poor, and the flame retardant...
