Problems solved by technology

[0009] 1. The use of a relatively single base resin, or the need to modify the resin, may help in terms of fire resistance, but it will cause an increase in production costs and an increase in preparation time. The combination of two resins can improve the fire performance of coatings
[0010] 2. The coating simply forms an outer cladding on the surface of the steel structure, which simply isolates oxygen, and the anti-c

Abstract

The invention relates to fire-retardant paint with a steel structure, which is prepared from the following raw materials proportioning by weight: 45 to 60 of composite substrate resin, 6 to 8 of melamine, 6 to 8 of pentaerythritol, 16 to 20 of ammonium polyphosphate, 4 to 10 of expansible graphite, 2 to 5 of nano magnesium hydroxide, 1 to 3 of zinc phosphate, 1 to 3 of zinc borate, 2 to 5 of aluminum hydroxide, 3 to 5 of aluminum polyphosphate, 6 to 9 of titanium dioxide, 0.5 to 0.8 of flatting agent and 15 to 20 of acetone. The paint has excellent capabilities of fire prevention and corrosion prevention.

Description

technical field [0001] The invention relates to a steel structure fireproof coating, which belongs to the field of steel structure coating preparation. Background technique [0002] Steel is a non-combustible building material, which has the characteristics of earthquake resistance, bending resistance and so on. In practical applications, steel can not only increase the load capacity of buildings relatively, but also meet the needs of architectural design aesthetics; it also avoids the defects of concrete and other building materials that cannot be bent and stretched. Therefore, steel is favored by the construction industry. Single-story, multi-story, skyscrapers, factories, warehouses, waiting rooms, waiting halls, etc. are all commonly used in steel. However, as a building material, steel has some unavoidable defects in fire prevention. Its mechanical properties, such as yield point, tensile strength and modulus of elasticity, will drop sharply due to the increase of temp...
