Indoor water-based fireproof coating for ultrathin steel structure

Abstract

The invention relates to the field of fireproof coatings, in particular to an indoor water-based fireproof coating for an ultrathin steel structure. The indoor water-based fireproof coating is prepared from following raw materials in parts by weight: 10-25 parts of water, 20-35 parts of synthetic emulsion, 0.2-0.6 parts of a dispersing agent, 0.2-0.6 parts of a wetting agent, 0.1-0.5 parts of a defoaming agent, 0.1-0.3 parts of an anticorrosive agent, 0.8-2 parts of a coalescing agent, 5-10 parts of titanium dioxide, 5-10 parts of aluminum hydroxide, 15-25 parts of ammonium polyphosphate, 7-15parts of melamine, 5-10 parts of pentaerythritol, 2-5 parts of expanded graphite, 2-5 parts of a reinforcing agent and 0.4-1 part of a thickening agent. The product is low in processing cost, high inspray coating efficiency, environmentally friendly and easy to transport, compactness and strength of a foaming carbon layer are high, and fireproof performance is high.

Description

technical field [0001] The invention relates to the field of fireproof coatings, in particular to indoor water-based ultra-thin steel structure fireproof coatings. Background technique [0002] Due to the advantages of quick construction, simple manufacturing process, easy adoption of industrialized production, and short construction and installation period, steel structure buildings have been widely used in industrial buildings or public buildings in various fields, but the high temperature resistance of steel structure materials is poor. It is easy to deform, and in the event of a fire, when the temperature of the steel structure reaches above 500 degrees, it may all collapse instantaneously. Therefore, in order to improve the fire-resistant grade of steel structures, it is necessary to coat fire-resistant coatings on the surface of steel structures. However, the existing fire-resistant coatings for steel structures, especially indoor ultra-thin fire-resistant coatings for...

[0002] Due to the advantages of quick construction, simple manufacturing process, easy adoption of industrialized production, and short construction and installation period, steel structure buildings have been widely used in industrial buildings or public buildings in various fields, but the high temperature resistance of steel structure materials is poor. It is prone to deformation. In the event of a fire, when the temperature of the steel structure reaches above 500 degrees, it may collapse instantly

Therefore, in order to improve the fire-resistant grade of steel structures, it is necessary to coat fire-resistant coatings on the surface of steel structures. However, the existing fire-resistant coatings for steel structures, especially indoor ultra-thin fire-resistant coatings for steel structures, are all organic solvent-based, flammable and explosive, and difficult to transport and store. All must be implemented in accordance with the requirements of dangerous goods; in addition, it emits a strong smell of harmful substances, which is harmful to the environment and human body, and is not environmentally friendly; and the drying speed is slow during construction, and organic solvents are required, and the construction efficiency is relatively low
