Polyolefin flame retardant
Synergistic flame retardant system refers to the two (as a flame retardant, a synergist flame retardant system) or more than two kinds of components, its effect is better than that of flame retardant components and flame retardant effect. In the flame retardant technology, polyolefin flame retardant is increasingly widely used, especially in the multi-functional flame retardant system.
Polyolefin mixed flame retardant synergistic reaction is not simply to improve the flame retardant efficiency, but also can reduce the content of some components in the formulation of flame retardant system, and can satisfy the requirements of increasingly stringent requirements of some applications of flame retardant.
The use of nitrides and phosphorus containing compounds has a significant synergistic effect. One of the outstanding advantages of polyolefin flame retardants is the low toxicity of their released gases. At the same time, the mechanism of carbon formation in the presence of polyhydroxy compounds in the presence of carbon materials is also discussed.
In the mid 60s, self extinguishing POM was prepared with NH4H2PO4 or (NH4) 2HPO4, and also with (NH4) 3PO4, but it could reduce the thermal stability of POM. A three in derivatives or when heated to produce three oxazine derivatives and a compound in heating, burning or hydrolysis can produce phosphoric acid and polyphosphoric acid phosphorus compounds from a mixture of flame retardant POM.
With phosphoric acid two guanidine salt, a melamine and ammonium polyphosphate reaction product or phosphorus and three triazine flame retardant POM, can reach UL94 V - 1 grade. Flame retardant POM was prepared by addition of methyl ethyl phosphate, 1,2- two (methyl phosphate) ethane melamine adduct and methyl ethyl phosphate / guanidine adduct. POM flame retardant was also obtained by using an amino ammonium polyphosphate as flame retardant.
Hatsuhiko Harashina developed a new POM flame retardant system, composed of red phosphorus, melamine, phenolic varnish compound as a flame retardant has good flame retardant effect on POM. When the flame retardant containing 10% phosphorus, 10% phenolic varnish and 5% melamine, which can make the application of flame retardant oxygen index POMincreased from 15.3% to 37.5%, and can reach UL94 V - 1 standard, when the thickness is 0.8mm no melt dripping phenomenon.
According to the characteristics of combustion and combustion mechanism of POM, with ammonium polyphosphate (APP) as flame retardant, melamine and pentaerythritol diphosphonate melamine (MPP) as auxiliary flame retardant, with flame retardant system composed of polymer absorbing agent by mixing aldehyde, adding POM in a flame retardant POM, after testing the oxygen the index can reach 50%, the vertical combustion to achieve the FV-0 level, and the processing conditions and the same as ordinary POM, can satisfy the requirement of use.

Anhui Research Institute of chemical industry in the 100 POM, adding 40 phr mixture of ammonium polyphosphate and pentaerythritol diphosphonate melamine salts 20 melamine and 10 continuous absorbing formaldehyde, preparation of flame retardant POM. Its oxygen index reached 50%, and the vertical combustion performance reached FV-0 level.
Fan Zhen in 100 POM by adding 40 phr MPP and ammonium polyphosphate (APP) mixture and 20 melamine, the oxygen index of flame retardant POM 49%; adding 30 phr MPP and APP mixture, 20 copies and 10 copies of the melamine formaldehyde absorption in 100 POM, the oxygen index of flame retardant POM 50%, UL94 V 0, the impact strength of both the decreasing rate were 18.2% and 23.6%, lower than the provisions of the "85" key contract requirements 30%.
Zhao Xiaoping with phosphorus nitrogen flame retardant A, homemade phosphorus nitrogen flame retardant B and MCA added melamine, according to a certain proportion of POM, can get up to 42% of the oxygen index of flame retardant POM material and V - 0 to UL94.
Nitrogen based flame retardants mainly refer to melamine and its derivatives, which can be used alone or in combination with other flame retardants. This kind of flame retardant has no halogen, low smoke, stable heat and light, high flame retardant efficiency and low price. It can be used in PA, PU, PO, PET, PS, PVC and epoxy resin.
The flame retardant POM can be quenched by three triazine derivative or dicyandiamide and its derivatives. 1,3,6- three (4,6- two cyano - three -2-) hexane flame retardant POM, flame retardant products up to UL94 V - 1 grade. Another German patent Japan Asahi Chemical Industry Corporation in the second half of 1978 introduced the use of TG- cyanuric acid ester flame retardant POM, when the content of flame retardant was 30 phr, the product of flame retardant effect of up to UL94 V - 1 level.
MCA composite flame retardant POM flame retardant was prepared by PUR-T coated nitrogen Flame Retardant Melamine melamine salt. MCA on POM flame retardant mainly endothermic cooling, MCA decomposed into melamine and isocyanate and decomposition products, melamine high temperature sublimation heat absorption can reduce the combustion temperature; concentration of combustible gas formaldehyde melamine and isocyanate further decomposed into CO2 and NH3 inert gas can produce oxygen and pyrolysis of POM diluted in the air, effectively inhibit combustion; and melamine can effectively absorb formaldehyde, improve the thermal stability of POM, in order to effectively improve the material performance degradation of flame retardant and POM directly caused by the mixture of coating, nitrogen flame retardant melamine cyanurate (MCA) produced by PUR-T composite flame retardant, and then mixed with POM can effectively improve the compatibility. When the total mass fraction of PUR-T/MCA was 30% (MCA mass fraction was 21%), the oxygen index of flame retarded POM increased from 15% to 26%.
