Nano composite material flame retardant
Nano flame retardant polymer composites is an important branch of nano materials, in 1976 published the first article about patent began nanoclay flame retardant nylon, nano flame retardants is booming, especially since the 1990 s, the nano flame retardant has become an important research hotspot in the field of flame retardant.
Nano flame retardant is a kind of new flame retardant technology, due to their high activity of nanoparticles, easy with certain groups in epoxy resin in physical or chemical effect, and thus enhanced the mechanical properties of resin composite materials, 2223, thermal properties and flame retardant performance of 24. Currently, nanomaterials used in polymer flame retardant have silicate materials, carbon nanotubes, carbon 6025, and graphene oxide.
The flame retardant properties of epoxy resin/graphene composites were studied by Zhou Wang et al. The results show that the addition of 1% of the oxidation of graphene can reduce the heat release rate peak (PHRR) from 900kw/m2 to 800kw/m2, and widen the thermal release rate curve. The ignition time was increased from 66s to 76s, which was considered to be caused by CO2 produced during combustion, while reducing the production of CO.
Han Huan wait 15 with phosphorus oxychloride, resorcinol m-phenylene diamine or bisphenol A as main raw materials was synthesized three hyperbranched phosphorus-containing flame retardants (3 - hydroxy phenyl) phosphate ester (HBPE), (3 - amino phenyl) phosphate amide (ABPA) and [4 - (p-hydroxy phenyl isopropyl) phenyl] phosphate (HBPPE).
Experiments show that three kinds of hyperbranched phosphorus-containing flame retardants for epoxy resin have good flame retardancy, including ABPA flame retardant efficiency and performance is best, when the adding amount of 23.8 wt %, the limit oxygen index of flame retardant epoxy resin reached 30%, the flame retardant performance for UL94 V - level 0. The infrared spectrum analysis showed that the flame retardant of superbranched phosphorus was not affected by the reaction to the curing of epoxy resin.
In this paper, the preparation of hexanoxy cyclotriphosphazene flame retardant was prepared by using the drip process, and the preparation of a large scale integrated circuit with halogen-free flame retardant was prepared with epoxy resin molded plastic (EMC). By the flame retardant investigation found that six phenoxy ring three phosphorus nitriles to epoxy resin has good flame retardant effect, the preparation of EMC can achieve UL94 V - level 0 flame retardant performance, the oxygen index reached 33.1%, flame retardant performance is superior to the traditional bromine-containing flame retardant system greatly, can be used for the preparation of large scale integrated circuit encapsulation with EMC.
Isopropylphenyl Phosphate(IPPP65)
Cas Number: 68937-41-7
Customs Code HS: 29199000
Tax Rebate: Current Isopropylphenyl Phosphate, Flame Retardant IPPP65 Tax Rebate Of 9%.
Net Weight 200KG / Galvanized Iron Drum (A Small Cabinet To Play With 16 Tons), 1000KG / IB Barrel (A Small Cabinet 18 Tons) Or 23 Tons ISOTANK.
Isopropylphenyl Phosphate(IPPP65) Uses:
Isopropylphenyl Phosphate, Flame Retardant IPPP65 Halogen-Free Phosphate Flame Retardant Plasticizer, Will Not Twice Pollute The Environment; In The Phosphate Ester Species Is A Viscosity, Phosphorus Content Is More Moderate A Model. This Product Is Colorless And Transparent, Good Compatibility, The Use Of Both Flame Retardant And Plasticizer, In The Flame Retardant And Plasticizer To Play A Balance Between The Role, But Also To Make The Processing Of The Same Material And Its Physical Properties.
By the structural characteristics of epoxy resin system of the preparation of flame retardant methods is contained in the epoxy resin molecular structure of the flame retardant elements migration not easily, not easy ooze, excellent and permanent flame retardancy, and good dimensional stability, thermal stability, oxidation stability, hydrolytic stability and high coal rate.
At present, structural flame retardant epoxy resin is prepared by the following two aspects: first, curing epoxy resin by synthesizing the curing agent containing flame retardant elements; The second is to introduce flame retardant elements through the active functional group containing the flame retardant elements and the epoxy base of the resin. In essence, both are introduced to flame retardant elements by reacting with epoxy.
Interrupt heat exchange mechanism of flame retardant is away most of the heat generated by the burning flame retardant materials, lead to materials not sustain the thermal decomposition temperature, therefore can't continue to produce flammable gas, self-extinguishing burning flame retardant effect.
For example, when the flame retardant material is burned by strong heat can be melt, easy to melt dripping molten material, to take away most of the heat, reducing the heat feedback to the material of the ontology, the combustion delay, finally may suspend the combustion process. So, the flammability of fusible materials is usually very low. But the downside is that dripping hot droplets may ignite other substances and increase the risk of fire.
Any thick cloth, large carpets and other goods that cannot be processed by ordinary equipment can be used for the flame retardant finishing of hand spray method in the last working procedure. The fabric that has pattern, tufted fleece, pile of hair on the surface of bulkiness is used, if the surface fluff pattern is damaged by the method of leaching, it is commonly used continuous spray method.
