Metal oxides and their salt flame retardants
Some metal oxides and their salt flame retardants are also the most effective synergants.
Levchik etc. The study found that in the ammonium polyphosphate flame retardant PA6 with some inorganic fillers such as CaCO3, ZnCO3, MnO2 can significantly improve the flame retardant properties of materials, but the CaCO3 and ZnCO3 won't affect the interaction between PA6 and ammonium polyphosphate, and MnO2 can accelerate the oxidation of PA6, generates more carbon, at the same time MnO2 will react with ammonium polyphosphate to generate phosphates vitreous body, raise the rate of residual carbon of system, and make the performance of the carbon layer heat insulation and isolation of combustible gas is improved. Lewinm's work confirmed that the compound of zinc and manganese has catalytic effect on ammonium polyphosphate/PER system.
Chun-ming tian, etc by limiting oxygen index, TGA and Fourier infrared spectrum (FTIR) detailed study of a series of oxide ZnO, CdO, MnO2, ZrO2, TiO2 metal oxides and salts, such as flame retardants in the expansion type flame retardant PP flame retardant effect. The results showed that the oxide with the ammonium polyphosphate/PER significant association between expansion flame retardant system effect, for the esterification and into charcoal has obvious catalysis reaction, but has no effect on the resulting residual product structure and, carbon, metal oxide can make more left to form stable carbon layer, a main reason to improve the performance of flame retardant materials.
Patents such as Po also mentioned with metal oxides such as MnO2, MnO, TiO2, ZrO2, CuO, Sb2O3 metal oxides and salts, such as flame retardant association effect of ammonium polyphosphate/PER agent used in polystyrene, high impact polystyrene (PS) and flame retardant of polybutadiene, not too much damage to the physical and mechanical properties of materials.
Li La2O3 as association effect agent such as applied to the expansion flame retardant PP, when the adding amount of flame retardant was 20%, very small amount of La2O3 can raise the limit oxygen index of PP at the same time take the material through the level UL94V0, for flame retardant PP have synergistic flame retardant and smoke suppression effect.

Tris(2-chloroethyl)phosphate(TCEP)Use:
1. Tris (2-Chloroethyl) Phosphate Has Excellent Flame Retardancy, Excellent Resistance To Low Temperature And UV Resistance, The Steam Can Only Be Used At 225 ℃ Above The Direct Ignition Can Be Fired, But The Fire The Source Is Immediately Self-Extinguishing. This Product Is A Flame Retardant Not Only Can Improve The Material Level Of Flame Retardant Materials, But Also Improve The Flame Resistance Of Water Resistance, Acid Resistance, Cold Resistance And Antistatic Properties. Commonly Used In Flame Retardant Nitrocellulose And Acetate Fiber As The Substrate Of Paint Coatings, Unsaturated Polyester, Polyurethane, Acrylic, Phenolic Resin, Can Also Be Used For Soft PVC Plastic Flame Retardant. This Product Is Used For The Amount Of Unsaturated Polyester 10% To 20%, In The Polyurethane Rigid Foam (Flame Retardant Polyether As Raw Material) Can Be About 10% In The Soft PVC Used As Auxiliary Plastic Flame Retardant When The 5% To 10%. Flame Retardants, Uranium, Thorium, Plutonium, Technetium And Other Rare Metal Separation Solvent Or Extractant.
2. This Product Is Widely Used In Chemical Fiber Fabrics, Cellulose Acetate As A Flame Retardant, In Addition To Self-Extinguishing, But Also Improve Water Resistance, Cold Resistance And Antistatic Properties. The General Amount Of 5 To 10 Copies. This Product Is An Excellent Flame Retardant For Synthetic Materials, And Has A Good Role In The Promotion, Widely Used In Cellulose Acetate, Nitrocellulose Varnish, Ethyl Cellulose, Polyvinyl Chloride, Polyvinyl Acetate, Polyurethane, Phenolic Resin , In Addition To Self-Extinguishing Products, But Also Improve The Physical Properties Of Products, Products Feel Soft, Also Known As Oil Additives And Rare Elements Of The Extractant, And Flame Retardant Rubber Conveyor Belt Is The Main Flame Retardant Materials , The General Amount Of Added 5% To 10%.
3. Used As Additive Type Halogenated Phosphate Flame Retardant And Plasticizer. Molecules In Both Phosphorus And Chlorine, Flame Retardant Effect Is Remarkable, Not Volatile And Hydrolysis, Good Stability To Ultraviolet Light. Applicable To Phenolic Resin, Polyvinyl Chloride, Polyvinyl Acetate, Polyurethane And So On. Also Used As Nitrocellulose Coating Flame Retardant, PVC Flame Retardant Plasticizer, Metal Extractant, Gasoline Additives And Polyimide Processing Aids And So On. Can Improve Water Resistance, Weatherability, Cold Resistance, Antistatic Property. Reference Dosage 5% To 20%.
Wu was studied by TGA, FTIR and SEM in detail such as the main group metal oxides Bi2O3 and Sb2O3 and SnO2 in PP/ammonium polyphosphate/DPER the synergy of flame retardant system, found a small amount of metal oxide can improve the limit oxygen index of system; TGA studies show that Bi2O3 can inhibit the decomposition of ammonium polyphosphate/DPER in high temperature and increase the residual carbon rate. TGA and FTIR studies showed that Bi2O3 changed the release of NH3 and phosphorus oxides during degradation and improved the efficiency of flame retardation.
Further study found that the transition metal oxides such as MnO2, ZnO, Ni2O3 for PP/ammonium polyphosphate/DPER flame retardant system has the association effect, because the transition metal ions has special extranuclear electron configuration mode (with the d orbitals), ionic radius, etc., can be strong interaction with the ammonium polyphosphate, generate complexes, makes the PP/ammonium polyphosphate/DPER containing Ni2O3 system at high temperature melt and the release of NH3 can better match, to improve the flame retardant performance of materials is the most effective.
Liu, etc to use metal oxide flame retardant ammonium polyphosphate/PER of styrene-butadiene rubber, studies have shown that adding 3.4 servings of ZrO2 can make the material level UL94V0, ZrO2 can enhance the stability of flame retardant system at high temperature, increase the rate of residual carbon, ZrO2 reacts with ammonium polyphosphate ZrP2O7, flame retardant samples containing ZrO2 with carbon structure is more compact, effectively improve the flame retardant properties of materials.
Nian-hua huang and so on the copper oxide and ammonium polyphosphate for PA6 composite flame retardant treatment, the results show that the copper oxide can reduce the initial decomposition temperature of PA6 and thermal weight loss rate, improve the activation energy of pyrolysis, promote the alkyl amide bond rupture, changed the thermal degradation pathway of PA6. Ammonium polyphosphate and PA6 react to produce phosphate-carbon esters, which have good thermal stability at high temperature, which is conducive to the improvement of flame retardant performance.
Chen will assist effect agent such as formic acid nickel used in ammonium polyphosphate/PER treatment of PP, studies have shown that formic acid nickel limit oxygen index of the samples significantly increased, and the thermal stability of PP system and residual carbon microstructure changes, the content of catalyst within 0.1% ~ 5% increased gradually, the sample of the limit oxygen index gradually increases; As the content of catalyst increases further, the limit oxygen index decreases.
