Due to the current market chaos, the quality of tunnel fire retardant materials is also very different, some illegal businesses, in order to bring huge profits,

As a result, raw materials are reduced in the production process of tunnel fire-resistant and flame-retardant materials, so the overall quality is reduced, and the phenomenon of falling off soon after painting,

Moreover, the fire protection standards are also unqualified. How to choose good quality tunnel fire retardant materials, please see the following introduction.


The common types of bases in the construction of fire retardant materials are cement base, gypsum base, wood base and metal base.

Among them, the cement-based base includes concrete, cement mortar, mixed mortar, air-entrained concrete, various lightweight cement-based boards,

block materials, etc. Such materials are all porous and brittle materials with high water absorption and high alkalinity; the strength varies in a wide range due to different types.

For example, the first poured concrete base has high strength and is very strong, and the paint can be applied directly after removing the oil contamination;

The strength of the aerated concrete base is very low. In order to obtain a good coating effect, it must be treated with an interface agent before coating;

The gypsum base is similar to the cement base except that the acidity and alkalinity are close to neutral, which is different from the cement base.


Fire-retardant and flame-retardant materials for tunnels have strong adhesion, frost resistance, moisture resistance, water resistance and good weather resistance. At the same time, it also has the effects of noise reduction, anti-eye chord and decoration.

The product is safe, non-toxic, non-polluting, fast drying, excellent in fire and flame retardant properties, and has functions such as heat insulation and sound insulation. It is very popular among fire departments, design units,

Well received by users such as construction companies.


The tunnel fire-resistant and flame-retardant material can withstand a fire of more than 1000°C within 30 minutes, so the coating has strong thermal insulation and light resistance.

The performance is also stable under the impact of high temperature flame; the corrosion of the inner wall of the tunnel caused by the acid exhaust emitted by the vehicle is reduced; the coating can be decorated twice to meet different design requirements.

After the fire-retardant and flame-retardant materials, in order to prevent the site from falling off, we need to carry out regular maintenance, so as to ensure that the paint is not damaged,


At the same time, it can better improve the use time, of course, its maintenance is also very convenient, and it is not as complicated as imagined.
