Halogen Free Flame Retardant Additives Safe Flame Retardant Smoke Suppressant

1. Description

    Halogen Free Flame Retardant Additives Safe Flame Retardant Smoke Suppressant is easy to use. It can be added instead of mineral powder when the asphalt mixture is mixed, and no additional production process will be added.  Mainly used in relatively closed spaces such as tunnels and underground passages, which greatly reduces the possibility of road burning when accidental fire occurs. Compared with traditional flame retardants, ZTA flame retardant is a completely environmentally friendly and non-toxic It will not release harmful gas to human body when it is burned and decomposed.

    Asphalt burns easily at high temperatures and is difficult to extinguish, and releases a large amount of smoke and toxic gases. In the tunnel, once a fire occurs, the toxic gas released by the burning of asphalt will seriously threaten personal safety. At the same time, the combustion will cause the temperature in the tunnel to rise and poor visibility, making rescue difficult and causing explosions and other accidents.

2. Mechanism of flame retardant

• Asphalt flame retardants can capture the highly active free radicals (HO- and H-) in the reaction at the initial stage of combustion, and inhibit the occurrence of chain reactions to fundamentally prevent combustion.
• Asphalt flame retardant can decompose incombustible gas, dilute the oxygen concentration and combustible gas concentration in the combustion zone, and prevent the spread of combustion.
• Asphalt flame retardant can decompose incombustible gas to dilute the concentration of combustible gas and prevent the spread of combustion.

3. Effect of flame retardant

1. Improve the flash point and oxygen index of asphalt, making it difficult to burn.

2. Reduce the emission of bitumen combustion smoke, reduce the probability of casualties in enclosed spaces such as tunnels or tunnels, and buy more time for firefighting and medical personnel.

3. Reduce the amount of smoke emitted and reduce the harm to operators.

4. After the asphalt pavement burns, the quality loss is small, the flying loss is small, and the residual stability is high.

4. Common flame retardant problems

1. Single component, low flame retardant efficiency, large addition amount, such as magnesium hydroxide, aluminum hydroxide, etc.

2. The product precipitates, which affects the appearance and releases toxic and harmful gases.

5. Product advantages

The mixing method is simple, and it is added directly and dry-mixed with the aggregate.

Halogen-free, non-toxic, environmentally friendly.

Good flame retardant effect, small addition amount, easy to disperse, good workability in construction.

It has good smoke suppression and flame retardant effect, and has excellent thermal stability and light stability.
