Phospho-nitrogen flame retardant
2017-9-25 11:40:47
Phospho-nitrogen flame retardant is an expansive flame retardant. The expansion type flame retardant is a kind of environmental protection type flame retardant which has developed rapidly in recent years. It is the main active component of phosphorus and nitrogen, without the halogen, and without the use of antimony oxide as the aid agent. When the materials or products are burned, only a small amount of smoke is released, and there are no poisonous gases such as hydrogen halide, which can also prevent the production of molten droplets.
Phosphorus - nitrogen flame retardant which is mature and has industrial production of a charcoal and XPM CN - 329-329, they are in the same molecule containing expansion flame retardant effect of three components (acid source, carbon source, air source) compounds, often used for flame retardant polyolefin.
In 2001, Shieh et al. reacted with DOPO and formaldehyde to synthesize the reactive phosphor monopm, and subsequently reacted with melamine, formaldehyde, phenol, and the phosphorus-containing phenolic resin odopm-mpn. Will ODOPM - MPN is used for curing epoxy resin, the curing of the mechanical properties and flame retardant performance has improved, burning smoke less, this kind of new curing agent of phosphorus and nitrogen synergistic effect on performance of resin has good improvement.
Liu chang in 2006, such as chlorinated spiro phosphate reaction with hydrazine hydrate, and then substituted benzene and formaldehyde reaction by a series of high symmetry structure, relative molecular weight, the paper contains more aromatic carbon and phosphorus heterocyclic structure of phosphorus - nitrogen flame retardant TDSUB. TDSUB thermal stability performance is good, carbon residue rate can amount to 40% of 600 ℃. In the epoxy resin e-41, 10% of the added amount can bring the value of LOI to 28. The phenomenon of no melting drop and bend in combustion is obvious, and the spline is expanded rapidly and rapidly carbonized. This indicates that TDSUB is a good type of expansive flame retardant.
Reports, such as 2007 Ma will spiro phosphorus oxychloride with 4, 4 '- diamino diphenyl methane reaction synthesis of a new type of phosphorous and nitrogen structure convergent expansion flame retardants (PDSPB), the main stage of decomposition of the polymer at above 300 ℃, 600 ℃ carbon residue rate can reach 42%. The flame retardant and ABS resin were mixed, and the initial decomposition temperature of pure resin decreased, but the rate of residual carbon and LOI value increased with the increase of adding quantity. The combustion performance of ABS and ABS/PDSPB blends was tested by conical calorimetry, and the results showed that the heat release rate decreased significantly with the addition of PDSPB.
Tris(2-butoxyethyl)phosphate(TBEP)Use
This Product Is Flame Retardant Plasticizer, Mainly Used For Polyurethane Rubber, Cellulose, Polyvinyl Alcohol And Other Flame Retardant And Plasticized, With Good Low Temperature Characteristics. Use Of Tris(2-butoxyethyl)phosphate(TBEP) For Flame Retardant Plasticizers And Processing Aids For Rubber, Cellulose And Resins. It Is Recommended For Use In Acrylonitrile-Based Rubbers, Cellulose Acetate, Epoxy Resins, Ethylcellulose, Polyvinyl Acetate And Thermoplastic And Thermoset Polyurethane. Phosphobutyrate (TBEP) Is Also Used As A Defoamer (Antifoam Agent) In Coatings, Detergents And Textiles. Has A Good Low Temperature Characteristics. This Product Can Also Be Used For Nitrocellulose, Ethyl Cellulose, Acrylic Plasticizer, Can Make Products With Transparency And Good Resistance To UV Performance.
PDBPP was synthesized from pentaerythritol, trichlorophosphate and 4, 4'- diaminodiphenylmethane in 2008. The study shows that PDBPP can significantly improve the thermal stability and flame retardant properties of PP. It is found that the addition of metal chelating compound can further improve the flame retarding performance of PDBPP and significantly reduce the heat release rate. The degradation products of metal ions and PDBPP can form dense mesh structures through salt Bridges, resulting in the formation of denser carbon layers. This research provides a new way of thinking about the development of flame retardants.
In 2009, tang anbin et al. reported a phosphorus-nitrogen flame retardant with DOPO and triazine. Good thermal stability of the flame retardant, flame retardant efficiency is high, can be used as reactive flame retardant epoxy resin, polyurethane and other thermosetting resin used for the flame retardant, and can be used as additive flame retardants used in ABS, halogen-free flame retardant nylon engineering plastics.
In 2010, Xiang et al. reported that the new type of expansive flame retardant SPDC was synthesized by the reaction of spironyl chloride and dicyandiamide. SPDC good thermal stability, 700 ℃ carbon residue rate of 31.6%. The SPDC and the APP use [m (SPDC) : m (APP) = 3:1], the flame retardant effect is the best. 30% of the added amount can make the LOI value of PP up to 38.5 and the vertical combustion reaches v-0. The mechanical properties of flame retardant PP are not significantly reduced.
Phosphine nitrile (phosphazene) is a kind of skeleton by phosphorus and nitrogen atoms arranged alternately compounds, they are the excellent properties of both inorganic and organic matter, and therefore has wide range of application in the field of flame retardant and good application prospect.
In 2001, Huang et al. synthesized NPAZ from cyclotriphosphine and nitrogen heterocyclic propane, and used to cure water-based polyurethane (PU). NPAZ is used as crosslinking agent in PU and as a synergistic flame retardant with phosphorus and nitrogen. When NPAZ added 1.5%, the thermal stability, flame retardant performance and mechanical properties of PU were significantly improved.
