Abstract

The invention belongs to the technical field of coating processing, and particularly relates to a water-based fireproof coating which comprises the following substances in parts by weight: 25-30 partsof vinyl acetate-acrylic emulsion, 6-10 parts of organic silicon resin, 4-7 parts of alumina fiber, 2-4 parts of thickener, 0.5-1 part of defoamer, 1-3 parts of silane coupling agent, 3-5 parts of ammonium polyphosphate, 2-5 parts of potassium tripolyphosphate, 1-4 parts of paraformaldehyde, 7-10 parts of compound modified filler and 80-85 parts of deionized water. The coating provided by the invention has very strong temperature resistance and fire resistance, and is high in overall mechanical strength and good in use stability. In addition, the preparation method of the coating is simple and easy to commercialize, popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of paint processing. More specifically, it relates to a water-based fireproof coating and a preparation method thereof. Background technique [0002] With the continuous improvement of the appearance and function of buildings, steel structures have been widely used in the modern construction industry due to their high strength, good toughness, light weight, good vibration resistance and impact resistance, and easy manufacturing and use. . The steel structure is mainly a metal material with good thermal conductivity, so it has the disadvantages of poor fire resistance and easy corrosion. When the temperature exceeds 250°C, the material changes greatly and the strength gradually decreases. When the temperature reaches 500°C, the steel enters the plastic state and cannot continue to carry the load, resulting in the collapse of the building and causing casualties and economic losses. Therefore, the fire prev...
