磷阻燃剂PA6

磷基阻燃剂包括有机磷基阻燃剂和无机磷基阻燃剂。其中，有机磷阻燃剂主要包括磷酸三酚酯、磷酸三酯、磷酸丙烯苯酯和磷酸丁苯酯。无机磷阻燃剂主要包括红磷和聚磷酸铵

磷酸酯具有阻燃和塑化的双重功能。它们可以抑制燃烧，提高聚合物材料的加工流动性。然而，有机磷阻燃剂的热稳定性和氧稳定性较差，在与熔点较高的PA6复合加工过程中容易分解，因此其阻燃性能和材料力学性能较少使用

红磷具有来源广、价格低、含磷量高、添加量小、毒性低、抑烟、阻燃效果好等优点。红磷作为阻燃剂已经使用了很长时间。它被用作尼龙零件的阻燃剂。这种药剂在欧洲使用得更多。在400-500℃时，红磷会将聚合反应还原为白磷，白磷会在高聚物燃烧环境中被氧化为粘性的含氧酸，并产生水。这种酸覆盖在燃烧材料的表面，起到保护和屏蔽作用，对聚合物有很强的脱水和碳化作用。它可以在燃烧材料的表面形成稳定的玻璃碳化层，碳层可以保护外部，氧气、热量和挥发性可燃物从内部聚合物基体中分离，并有助于中断燃烧。红磷热解产物中的PO·自由基进入气相后，可以捕获燃烧火焰中的H·HO·自由基，从而减缓或阻断聚合物燃烧过程中的链式反应，实现气相阻燃。目的

Product Details

nylon 6 flame-retardant plastic material

Phosphorus flame retardant flame retardant PA6

Phosphorus-based flame retardants include organic phosphorus-based flame retardants and inorganic phosphorus-based flame retardants. Among them, the organic phosphorus flame retardants mainly include triphenol phosphate, triester phosphate, propylene benzene phosphate, and butyl benzene phosphate. Inorganic phosphorus flame retardants mainly include red phosphorus and ammonium polyphosphate.

Phosphate esters are characterized by dual functions of flame retardancy and plasticization. They can inhibit combustion and improve the processing fluidity of polymer materials. However, organophosphorus flame retardants have poor thermal and oxygen stability and are easily decomposed during composite processing with PA6, which has a higher melting point, so that its flame retardant performance and material mechanical properties are less used.

Red phosphorus has the advantages of wide sources, low price, high phosphorus content, small addition, low toxicity, smoke suppression, and good flame retardant effect. Red phosphorus has been used as a flame retardant for a long time. It is used as a flame retardant for nylon parts. The agent is used more in Europe. At 400-500℃, red phosphorus will reduce polymerization to white phosphorus, and white phosphorus will be oxidized to viscous oxyacid in the high polymer combustion environment where water is generated. This kind of acid covers the surface of the burned material, which plays a protective and shielding role, and has a strong dehydration and carbonization effect on the polymer. It can form a stable glass carbonized layer on the surface of the burned material, and the carbon layer can protect the outside The oxygen, heat and volatile combustibles are separated from the internal polymer matrix and help to interrupt the combustion. After the PO·radical in the pyrolysis product of red phosphorus enters the gas phase, it can capture the H·HO·radical in the combustion flame, thereby slowing down or blocking the chain reaction in the polymer combustion process, and achieving gas-phase flame retardancy. purpose.
