It is recommended to add 1%-3% of the finished paint, and the amount should be increased in aluminum alloy and stainless steel substrate, which varies according to the formulation system. Be cautious of using non-acid resistant pigments and hollow fillers, which may cause darkening and blackening to the untreated aluminum powder surface.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The flame retardant additives of the tunnel fireproof coating must not only be able to organically cooperate with the base material to make it have ideal fire and heat insulation, but also improve the weather resistance, water resistance and other physical and chemical properties of the coating, which is suitable for the environmental conditions used in the tunnel. The flame retardants used in tunnel fireproof coatings include aluminum hydroxide flame retardants, borides containing crystal water, zinc compounds, etc., with better effects, and they can also act as curing agents.

The particle size of the flame retardant has a great influence on the fire and heat insulation performance and some application properties of the tunnel fireproof coating. The particle size is large, easy to precipitate, and the utilization rate of the flame retardant is low. Generally, the particle size can be applied when the particle size is 2~3mm. But its adsorption power is poor, and the washing resistance is not satisfactory enough; ptfe modified pe wax msds the particle size is small and the density is high. In order to improve the diffusibility of the flame retardant, the particle size of the flame retardant is generally about 1mm, so that the performance of the tunnel fireproof coating can reach the best.

The development trend of flame retardants
Since most building materials, especially interior decoration materials, are flammable, the fire problems caused by their application have become very prominent. Therefore, changing the flammability of materials has attracted more and more attention. From the 1960s to the 1980s, the research and development of flame retardants have become more extensive and in-depth. Various flame retardants and flame retardant products have emerged rapidly, many of which have been put into industrial production, and their output and consumption have increased year by year.
At present, when people choose flame retardants, they first choose environmentally friendly flame retardants that are pollution-free, non-polluting, non-radioactive, and non-toxic during use. With the improvement of people’s quality of life, people require protection of their own living space.

The voices are getting louder and the environmental regulations are getting stricter. From the perspective of the development trend of flame retardants, the ultra-fine, flame retardant, low-smoke, and surface modification of inorganic flame retardants, fillers and smoke suppressants are topics that the flame retardant industry and chemists should focus on. . Therefore, the development of green and environmentally friendly sun-burning agents has become the development trend of the flame retardant industry. The current domestic and foreign research and development trends of flame retardants for fire retardant coatings are as follows.
