Abstract

The invention discloses hydrotalcite type water-based facing fireproof coating, which is composed of the following components: 3-7 parts of carbonate hydrotalcite; 1-2 parts of cellulose; 4-6 parts of a dispersant; 0.5 to 2 parts of a defoaming agent; 6 to 11 parts of pentaerythritol; 15 to 20 parts of ammonium polyphosphate; 8 to 12 parts of melamine; 1-3 parts of light calcium carbonate; 2-4 parts of titanium dioxide; 8 to 12 parts of emulsion; 1-3 parts of urea; and 33-42 parts of water. According to the invention, the carbonate hydrotalcite with flame-retardant effect is adopted to replace part of pentaerythritol, ammonium polyphosphate and melamine, part of skeleton, foaming and flame-retardant effects are undertaken, and the cost of the fireproof coating is greatly reduced while the same performance is achieved. In addition, due to the fact that hydrotalcite is heated to generate carbon dioxide and water vapor, flame retardance is achieved, meanwhile, the temperature of a combustion area is reduced, and the flame-retardant time of the fireproof coating is prolonged. Moreover, the hardness of the hardened hydrotalcite is higher, so that the impact resistance of a coating film of the facing fireproof coating is improved. Compared with ammonium polyphosphate, the solubility of the carbonate type hydrotalcite is lower, so that the water resistance of the coating film of the facing fireproof coating containing the carbonate type hydrotalcite is more excellent.

Description

technical field [0001] The invention relates to the technical field of fireproof coatings, in particular to a hydrotalcite-type water-based decorative fireproof coating. Background technique [0002] In recent years, fires have occurred frequently in various places. The reason is not difficult to find. Although the main structure of modern buildings is constructed of non-combustible materials, there are still a large number of flammable and combustible interior decoration materials and furniture in the entire building. It is a risk factor for the occurrence and spread of fire. The best way to make some of the flammable parts fire-resistant and flame-retardant is to coat them with excellent fire-resistant coatings to reduce their combustion levels and become non-combustible or flame-resistant. Once a fire breaks out, it can prevent the fire from spreading within a certain period of time. The current fireproof coatings in my country include decorative fireproof coatings, ste...
