Fireproof paint, preparation method of fireproof paint and flame screen containing fireproof paint

Abstract

The invention discloses a fireproof paint, a flame screen containing the fireproof paint and a preparation method of the fireproof paint. The fireproof paint is prepared from the following raw materials in parts by weight: 30 to 40 parts of dehydration catalyst, 15 to 25 parts of carbonization agent, 30 to 35 parts of foaming agent and 60 to 70 parts of binding agent. According to the flame screen, a porous metal plate or a metal wire mesh structure is utilized as a base layer, the areal density is 1 to 6.0kg / m<2>, the diameter of each mesh is 6.0 to 150.0mm, and the surface of the base layer of the flame screen is coated by the fireproof paint. In a normal use state of the flame screen, air can freely circulate among meshes of the flame screen; when fire happens, a fireproof coating on the flame screen is heated to expand to form thermal-insulation fireproof paint to plug the meshes of the flame screen, heat and smoke are prevented from freely circulating in a breathing cavity of a curtain wall, and the fire is prevented from expanding horizontally or vertically. The flame screen can be widely applied to the places needing fire protection and requiring ventilation of electric power, metallurgy, petrifaction, chemical engineering, buildings and the like.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to a fireproof coating for building fireproof sealing, a preparation method thereof and a fireproof net containing the fireproof coating. Background technique [0002] Glass curtain wall has the advantages of beauty and transparency, and has been widely used in commercial and office buildings at home and abroad, especially in super high-rise buildings. With the continuous development of my country's economy, more and more glass curtain walls are used in buildings. At the beginning of the last century, people began to use double-glazed curtain walls in some buildings. The double-glazed curtain wall consists of two layers of glass plus an intermediate air layer and sunshade. The glass curtain wall that can use the air layer between the two layers of glass for ventilation is called a breathing curtain wall. This kind of curtain wall can get a lot of sunlight, provide good natural vent...

AI Technical Summary

Problems solved by technology

Metal mesh fireproof net is a fine mesh structure woven by metal wires, but the mesh structure has small pores, and the pores do not expand when exposed to fire. Inflammable gases and flames can pass through this type of metal mesh, and are easily destroyed. Dust clogged

Obviously, the "fireproof net" of plastic or metal mesh has no fireproof effect, and cannot be used in places that require both ventilation and fireproofing
