Ammonium triphosphate - Physico-chemical Properties
| Molecular Formula | (NH₄,H)ₙ+2PₙO₃ₙ₊₁ |
| Molar Mass | 309.05n |
| Use | Ammonium polyphosphate (APP) is the main variety of phosphorus flame retardant, which is used in fire extinguishing agent, flame retardant coating and flame retardant polymer material. It is an upgrading product of halogen flame retardant. Halogen flame retardants and their flame-retardant polymer materials thermally decompose at high temperatures to produce toxic fumes, such as polybrominated benzenes and polybrominated dibenzofurans, while 80% of fire hazards come from inhalation of excessive smoke, this is a fatal disadvantage of halogen-based flame retardants, and the EC has proposed to limit the use of such flame retardants, and will gradually phase out. Although ammonium polyphosphate flame retardant efficiency is not as good as the halogen flame retardant, but because it does not produce toxic substances when burning, good thermal stability and smoke-free non-toxic. Based on the above situation, ammonium polyphosphate flame retardant has been rapid growth. |
Ammonium triphosphate - Modification method
When ammonium polyphosphate is applied to flame-retardant materials, the addition amount is large, which reduces the mechanical properties of flame-retardant materials. On the one hand, ammonium polyphosphate is incompatible with organic polymers. Ammonium polyphosphate is an inorganic polymer with strong polarity. It cannot be blended well with the usual non-polar polymer polyethylene polypropylene. Its flame retardant materials have weak points and the mechanical properties of the materials decrease; on the other hand, ammonium polyphosphate has a certain degree of water solubility, which causes ammonium polyphosphate to exude from the flame retardant material and affects the flame retardant and mechanical properties.
Increasing the polymerization degree of ammonium polyphosphate can greatly reduce its water solubility and reduce exudation to a greater extent, but the surface polarity of ammonium polyphosphate has not changed. In order to improve the compatibility with organic polymers, ammonium polyphosphate usually needs surface modification treatment to reduce its surface polarity and water solubility. The modification methods include microcapsule coating, coupling agent blocking polarity point, organic amine ion exchange, etc. These measures are usually effective.

| modification method | when ammonium polyphosphate is applied to flame retardant materials, the addition of ammonium polyphosphate is large, which reduces the mechanical properties of flame retardant materials. On the one hand, ammonium polyphosphate is incompatible with organic polymers. Ammonium polyphosphate is a strong polar inorganic polymer, which cannot be well mixed with the normal non-polar polymer polyethylene polypropylene, and its flame retardant material has a weak point, on the other hand, ammonium polyphosphate has a certain water solubility, which leads to the exudation of ammonium polyphosphate from the flame retardant material, which affects the flame retardant and mechanical properties. Increasing the degree of polymerization of ammonium polyphosphate can greatly reduce its water solubility and greatly reduce the exudation phenomenon, but the surface polarity of ammonium polyphosphate has not changed. In order to improve the compatibility with organic polymers, ammonium polyphosphate usually needs surface modification to reduce its surface polarity and water solubility.
