Thick section steel structure fireproof coating and construction technology thereof

Abstract

A thick section steel structure fireproof coating is characterized in that the thick section steel structure fireproof coating is composed of a fireproof coating, a binder and water according to a weight ratio of 1:0.08:1.2. The NH-AWS indoor thick section steel structure fireproof coating is a water-soluble coating, is prepared by compounding the inorganic binder with many flame-retardant heat insulation coatings, and a coat formed by the thick section steel structure fireproof coating can form a heat insulation layer after meeting fire, so a steel member is insulated and protected from heat in a fire hazard, and does not generate any harmful gases at a high temperature, and the strength of the steel member does not acutely decrease under the action of the high temperature of the fire hazard, thereby the collapse of buildings is avoided; and the NH-AWS indoor thick section steel structure fireproof coating has the advantages of high binding strength, excellent water resistance, good weather ability, light specific gravity, long fireproof time, and suitableness for the fireproof protection of the naked parts of steel structure buildings with high fireproof limit.

Description

[0001] Technical field The present invention relates to a steel structure fireproof coating, specifically a thick steel structure fireproof coating and its construction process. Background technique [0002] With the development of society and the continuous improvement of people's living standards, especially the rapid development of industrial economy, people's material life and economic life have been greatly improved. [0003] 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 In factory buildings, large stadiums, airports, bridges, three-dimensional garages and other places, in order to ensure their long-term exposure to the sun, wind and rain, and fire resistance, anti-corrosion and fire-resistant coatings are usually pai...

Problems solved by technology

[0004] Most of the existing steel surface materials are simply brushed or sprayed, which can only play a role in wind erosion resistance, and the steel structure and surface coating painted with fireproof coatings cannot be well bonded together, and the service life is short
