Problems solved by technology

However, the existing polymer emulsions have poor UV resistance and poor weather resistance, and are prone to cracking, fading, and flowering after being irradiated by ultraviolet rays.
In addition, due to the different properties of the steel-concrete structure and organic materials, thermal expansion and contraction are not the same, resulting in cracking and peeling of the paint surface or paint surface
In addition, all kinds of emulsion coatings contain chemical substances such as ethylene glycol (antifreeze agent) and ammonia water (pH value regulator), which will produce harmful gases such as volatile organic compounds (VOC) and formaldehyde during the construction process, which is environmentally friendly. Poor performance can have adverse effects on people's physical and mental health
In addition, the existing polymer emulsions do not have radiation protection and stain resistance

Abstract

The invention discloses radiation-proof tunnel fireproof paint. The radiation-proof tunnel fireproof paint comprises the following components in proportion by weight of portland cement, perlite, calcined kaolin, expanded vermiculite, fly ash cenospheres, sodium alkylnaphthalenesulfonate, polydimethylsiloxane, polymer modified oxidized graphene and KH-560. The radiation-proof tunnel fireproof paint has the advantages of being excellent in fireproof performance, high in adhesive force, good in dirty resistance, high in abrasion resistance, excellent in weather resistance and water resistance, good in radiation resistance, environmental-friendly and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a fireproof coating for radiation-proof tunnels. Background technique [0002] Tunnel is a traffic channel that achieves the shortest distance, occupies less land, and has the least damage to the natural environment and landscape, and has become a common building in modern traffic engineering. Due to the particularity of the tunnel building structure, its environment is relatively airtight, and the density of people passing through is relatively high. Once a fire accident occurs in the limited tunnel space, it is very difficult to extinguish the fire. Often, the tunnel is partially burnt down due to the poor fire prevention ability of the tunnel. Cause heavy casualties and property damage. Under normal circumstances, the tunnel wall is a reinforced concrete structure. Since the reinforced concrete is not resistant to high temperature, the reinforced concrete will crack until th...
