Abstract

The invention relates to the technical field of paint, in particular to thick high-temperature-resistant steel structure anticorrosive paint and a preparation process thereof. The thick high-temperature-resistant steel structure anticorrosive paint comprises, in weight percent, 1-2% of organic pigments, 5-7% of fireproof packing, 2-3% of preservatives, 0.2-0.6% of color paste, 2-3% of modified acrylic waterproof emulsion, 5-6% of epoxy resin, 0.4-0.6% of thickening agents, 1-2% of dispersing agents, 1-2% of defoaming agents, 1-2% of leveling agents, 2-3% of coalescing agents and 68.8-79.4% ofwater. The preparation process of the thick high-temperature-resistant steel structure anticorrosive paint includes the steps: first, weighing components according to the percent; second, preparing afinished product, to be specific, adding the components weighed in the first step into a container, and sufficiently stirring the components for 30-40 minutes. The paint is good in corrosion resistance, environmentally friendly and strong in degradability, and bacteria cannot be easily bred.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a thick anti-corrosion coating for high temperature resistant steel structures and a preparation process thereof. 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 In factories, large stadiums, airports, bridges, three-dimensional garages and nuclear buildings. 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 buildi...
