A kind of water-based thin coating type aluminum alloy fireproof coating and preparation method thereof

Abstract

The invention provides an aqueous thin coating type aluminum alloy fireproof coating material and a preparation method thereof, wherein the aqueous thin coating type aluminum alloy fireproof coating material is prepared by mixing the following raw materials by weight: 5-10 parts of an organosilicon modified acrylic emulsion, 25-30 parts of an acrylic polyester copolymer, 5-10 parts of pentaerythritol triacrylate, 20-25 parts of ammonium polyphosphate, 3-5 parts of melamine, 5-9 parts of dipentaerythritol, 2-6 parts of bentonite, 15-20 parts of titanium dioxide, 0.2-0.6 part of hydroxyethyl cellulose, 0.1-0.5 part of an anti-foaming agent, 0.3-0.5 part of a dispersant, 0.1-0.4 part of a bactericide, 0.2-0.8 part of a corrosion inhibitor, and 4-10 parts of water. According to the present invention, the aqueous thin coating type aluminum alloy fireproof coating material has advantages of uniform fineness, high bonding strength, long flame retardant time, good weather resistance, thin coating, environmental protection and the like; and the preparation method has characteristics of simple process, high production efficiency, stable product quality and environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of fireproof paint and its preparation, and in particular relates to a water-based thin coating type aluminum alloy fireproof paint and a preparation method thereof. Background technique [0002] In recent years, all walks of life are developing towards energy conservation and environmental protection, and the awareness of energy conservation and environmental protection in the transportation industry is gradually increasing. For example, vehicles, trains, ships, airplanes and other vehicles are all transforming towards lightweight. Lightweight aluminum alloys are more and more widely used in the transportation industry due to their excellent mechanical properties and mechanical properties, as well as high cost performance. Throughout the news reports, it can be seen that fires on vehicles will cause huge property losses, and sometimes serious casualties. Therefore, it is necessary to take fire prevention me...

Problems solved by technology

Throughout the news reports, it can be seen that fires on vehicles will cause huge property losses, and sometimes serious casualties, so it is necessary to take fire prevention measures for aluminum alloy products used in vehicles

[0003] At present, there are many water-based fireproof coatings on the market, which can be used for fireproofing metal structures, wood structures and polymer composite structures. However, the existing fireproof coatings have weak adhesion to metal structures, especially aluminum alloy materials, and are easy to dry and crack. Coating thickness is too thick, etc.
