Application of Flame Retardant in Flame Retardant Technology of FRP

The so-called flame retardant is used to improve the flame retardancy of the material, that is, to prevent the material from being ignited and suppress flame propagation. Most of them are compounds of the Group V, VII and III elements of the periodic table; especially phosphorus and bromine. , chlorine, cesium, and aluminum compounds.

In the flame retardant technology of glass steel, the addition of flame retardants is the most commonly used method.

At present, commonly used additive flame retardants include inorganic flame retardants (such as aluminum hydroxide, magnesium hydroxide, red phosphorus, and phosphate) and organic flame retardants (halogen flame retardants, organic phosphorus flame retardants, Nitrogen-based flame retardants, boron-containing flame retardants, silicon-containing flame retardants, macromolecular intumescent flame retardants, etc.) Also include some smoke suppressants and synergists (eg, antimony trioxide, tin oxide, molybdenum oxide) Ammonium octa molybdate, ammonium decadmium molybdate, zinc oxide, zinc borate, etc.).

Different flame-retardant additives have different effects on improving the combustion performance of FRP. Even if the flame-retardant additives account for different proportions in FRP, different combustion performances will be obtained.

According to actual needs, the glass fiber reinforced plastic material adopts a specific flame retardant technology to achieve the flame retardant effect while ensuring the performance parameters. However, its flame retardant properties are likely to change and fail due to aging due to the influence of the external environment.
