Abstract

The invention provides a fireproof coating for thick formed steel constructions. The coating is prepared from a fireproof filler, a fire retardant, a main binder, an auxiliary binder, a water-proofing agent and mica powder; the binding performance of the fireproof coating for the steel constructions is improved, meanwhile, the dosage of the fire retardant is optimized and the long fire resistance of the fireproof coating for thick formed steel constructions is guaranteed; other auxiliaries as the water-proofing agent are added to improve the water tolerance, anti-penetrability performance and weather fastness of the fireproof coating for the steel constructions are improved. The fireproof coating for the steel constructions has the characteristics of water tolerance, anti-permeability, fire resistance, impact resistance, simple preparation process, convenience for application, non-toxicity and harmlessness, long service life and the like. The fireproof coating for thick formed steel constructions is suitable for fireproof protection of the exposed parts of steel construction buildings high in fire endurance.

Description

technical field [0001] The invention relates to a fireproof material, in particular to a fireproof coating suitable for providing fireproof protection for steel structures used in high-rise buildings. Background technique [0002] With the development of industrialization, especially in the construction of large and medium-sized cities, steel structures have become a very important construction application material due to their fast and convenient construction advantages. As metal steel structures, they are mostly used in standard Factory buildings, large stadiums, airports, bridges, three-dimensional garages and other places. However, the fire resistance of steel structures is far inferior to that of brick-concrete structures. The critical temperature of steel is 540°C. When this temperature is reached, its bearing capacity will be reduced by about half. In a general fire, this temperature can be reached in about 15 minutes, leading to the collapse of the building. This c...
