Abstract

The invention belongs to the field of chemical engineering paint, and particularly relates to fireproof paint and a preparation method thereof. The fireproof paint is prepared from the following raw materials in parts by weight: 35 to 50 parts of paint substrate resin, 1 to 10 parts of deionized water, 30 to 60 parts of fireproof filling materials, 10 to 15 parts of titanium dioxide and 5 to 10 parts of paint curing agents. The fireproof filling materials are prepared from the following ingredients in parts by weight: 10 to 20 parts of covalent organic frameworks, 10 to 20 parts of ammonium polyphosphate, 5 to 10 parts of hydroxymethyl cellulose and 5 to 10 parts of expansible graphite. The fireproof paint has the advantages of high charring speed in case of fire and high charring intensity, and has certain anti-corrosion performance.

Description

technical field [0001] The invention belongs to the field of chemical coatings, in particular to a fireproof coating and a preparation method thereof. technical background [0002] Steel structure materials have the advantages of light weight, high strength, good seismic performance, easy installation, short construction period, and less environmental pollution. They are known as green building materials in the 21st century; with the rapid excavation and development of steel structure materials, Steel structures are widely used in the field of construction. In recent years, the application of steel structures in my country has entered a stage of rapid development, and has gradually reached the world's advanced level in the fields of steel structure manufacturing and processing. The steel structure is different from the traditional masonry structure and reinforced concrete structure. Although it is not a combustible material, the fire resistance of the steel structure itself...
