Common flame retardant has which?

1, chlorine flame retardant

近, chlorine flame retardant already separation is bromine flame retardant 取代, chlorine in flame retardant consumption amount in has decline.

2, bromine flame retardant

3, flame retardant

磷系 flame retardant 包括无 machine flame retardant and has machine flame retardant.

4, nitrogen flame retardant

commonly used flame retardant product types has poly amine, poly amine acid salt （MCA） and other, 往往需 add 入协同 agent, used for PA, PU, PO, PET, PS, PVC and other resin in. nitrogen /磷 is most commonly used flame retardant system.

5, type flame retardant

6, machine hydrogen oxidation material flame retardant

flame retardant, easy polymer flame resistant property function property additives, main/primary is for polymer/macromolecule material flame retardant design; flame retardant has multiple type type, use methods separation is add type flame retardant and reaction type flame retardant.

添 add type flame retardant is through machine mixed combined methods add to polymer in, make polymer tool has flame retardant property, currently add type flame retardant main/primary has has machine flame retardant and machine flame retardant, flame retardant （ has machine chlorine material and has machine bromine material ） and non 卤. has machine is bromine 系, nitrogen 系, nitrogen and and combined material is table/sheet flame retardant, machine main/primary is oxidation 二锑, hydrogen oxidation 镁, hydrogen oxidation aluminum, silicon and other flame retardant system.

reaction type flame retardant is as is types mono add polymerization reaction, therefore make polymer 本身含 has flame retardant formed separation, its advantages is for polymer material use property can effect/influence relatively small, flame retardant property 持久.

its 实, flame retardant types type more, can separation is: has machine flame retardant and machine flame retardant. has machine flame retardant main/primary separation chlorine 系, bromine 系, 磷系. machine flame retardant has hydrogen oxidation aluminum, hydrogen oxidation and other.

has machine flame retardant can separation is flame retardant and flame retardant, flame retardant advantages is use amount less, flame retardant efficiency high 且适应 property 广, its heavy disadvantages is 燃烧时生 formed a large amount of and has tool property gas 体, very large. flame retardant 不含卤索, flame retardant good, hot separation understanding generate gas low 烟, low 毒.

无 machine flame retardant separation understanding temperature degree high, remove has flame retardant outer, also has made and chlorine hydrogen formed function. its in hydrogen oxidation aluminum is flame retardant, 抑烟, filling large function 于一身 flame retardant, 无毒, 无腐蚀, stability property good, high temperature lower generate has gas 体, price low 廉, 源广泛. hydrogen oxidation in 340℃～490℃ between separation understanding. heat stabilized property good, tool has good flame retardant and 消烟效果, especially 适宜于 processing temperature degree relatively high polyolefin plastics.
