Problems solved by technology

However, there are many problems in the performance of fire-resistant coatings at home and abroad, such as poor fire resistance and weather resistance, and under the condition of being exposed in the shed for 3 years, its flame resistance is mostly reduced to 30% to 40% of the original
Therefore, how to choose the raw materials and proportions of ultra-thin steel structure fireproof coatings, so as to solve the current shortcomings of poor fire resistance and weather resistance, is particularly important.

Abstract

The invention discloses a water-borne nano ultra-thin steel structure fire retardant coating, which comprises a carbon source, an acid source, an air source and auxiliaries, and consists of the following components by weight percentage: 20-40% of acrylic ester emulsion, 10-30% of ammonium polyphosphate (APP), 5-15% of pentaerythritol, 1-10% of melamine, 1-10% of nanometer material, 0.001-5% of auxiliaries, and 10-30% of water. The invention also discloses a preparation method of the fire retardant coating. The prepared fire retardant coating has the characteristics of stable performance and good fire resistant performance, the thickness of the prepared fire retardant coating is no more than 2mm, and the fire reissuance duration of the prepared fire retardant coating is up to 120 minutes.

Description

Technical field [0001] The invention relates to a water-based nano ultrathin steel structure fireproof paint and a preparation method thereof, and belongs to the technical field of fire fighting materials. Background technique [0002] Economic and social development has promoted the development of the construction industry. Large-scale buildings such as exhibition halls, terminal buildings, large shopping malls, stadiums, high-end hotels and industrial plants are increasing, and they are developing in a large and beautiful direction. Its main load-bearing components Most are steel structures. [0003] For this reason, the fire protection of steel structures has attracted more and more attention. Although steel is a non-combustible material, its fire resistance is far worse than that of masonry and reinforced concrete structures. As the temperature increases, the mechanical strength of steel will decrease. When the temperature rises to the critical temperature of steel (generally...
