Description

technical field [0001] The invention relates to the technical field of fireproof coatings, in particular to a water-based fireproof coating for steel structures. Background technique [0002] Fire retardant coating is a special coating used to improve the fire resistance limit of the coated material. According to the different types of materials to be coated, fire retardant coatings are roughly divided into decorative fire retardant coatings, wood fire retardant coatings, steel structure fire retardant coatings, and so on. Steel is a non-combustible building material, which has the characteristics of earthquake resistance, bending resistance and so on. In practical applications, steel can relatively increase the load capacity of buildings, meet the needs of architectural design aesthetics, and avoid the defects of concrete and other building materials that cannot be bent and stretched. Therefore, steel has been favored by the construction industry. However, as a building m...
