Metal hydroxide inorganic flame retardant
Metal hydride, such as Al(OH)3 and Mg(OH) 2, are another class of inorganic flame retardants that are widely used.
Riva etc. The study found that the metal hydroxide inorganic flame retardant Mg (OH) 2 with ammonium polyphosphate and PA6 for ethylene/vinyl acetate copolymer (EVA) flame retardant processing, system has a better flame retardant performance, is mainly due to the Mg (OH) 2 and ammonium polyphosphate exist interaction during degradation, Mg (OH) 2 has promoted the release of NH3 ammonium polyphosphate degradation.
Castrovinci etc by cone calorimeter analysis showed that when used for styrene butadiene rubber flame retardant, ammonium polyphosphate than metal hydroxide inorganic flame retardant Al (OH) 3 is more effective, adding 60% of Al (OH) 3 to add 12% ammonium polyphosphate flame retardant effect, and 1% of Al (OH) 3 add ammonium polyphosphate processing styrene-butadiene rubber, produced obvious effect.
By studying the interaction between butadiene rubber and Al(OH)3 and ammonium polyphosphate, the formation of aluminum phosphate has adverse effects on the flame retardant system with single use of polyphosphate. There is obvious antagonistic effect of Al(OH)3 and ammonium polyphosphate in the flame retardant of butadiene rubber. Therefore, it should be further studied when the inorganic flame retardant of metal hydroxide and ammonium polyphosphate are in the system of different polymer systems.
In recent years, layered dihydroxyl oxide (LDH) has become another hot spot in the study of the expansion system. Studies have shown that a single LDH to improve the flame retardant properties of polymer, and ammonium polyphosphate intumescent flame retardant system distribution can obviously improve the efficiency of flame retardant, reduce the adverse effect of mechanical properties. Xu jianhua and others will be used in a certain range of nano-ldh and ammonium polyphosphate to be used for PA6/PP blending system, which can produce good synergistic effect.

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%.
Synergistic flame retardant effect may be due to the LDH in the process of heat release of the expansion flame retardant system needs a moderate amount of gas, producing magnesium aluminum composite oxide not only has large specific surface area, and has strong alkaline catalyst, and source of acid ammonium polyphosphate full role, promote the ammonium polyphosphate better catalytic PA6 / PP substrate rapid dehydration, crosslinking, charcoal, so as to realize acid source, carbon source, gas source the best match, effective play to the role of the condensed phase expansion flame retardant.
Wang guan is waiting to be used for flame retardant unsaturated polyester resins (UPR) with magnesium chloride, Al(OH) 3, polyphosphate complex. Results show that in the distribution of flame retardant system, brucite, Al (OH) 3, there is an obvious association effects between ammonium polyphosphate, brucite/Al (OH) 3 / ammonium polyphosphate for 2/1/1, composite flame retardant content is 40%, the composite material limit oxygen index was 33.8%, and the vertical combustion of FV - level 0, smoke density rank is 56.74, B1 level can meet the national electrical thermosetting plastic use requirement.
Zhang in aqueous solution, such as ammonium polyphosphate, PER, such as the insertion of LDH layers, and then the PP flame retardant treatment, compared with the traditional mixing method, a new processing method of flame retardant PP with more excellent pervious to light quality and mechanical properties. At 30%, the limit oxygen index reached 31%, and the UL94 test reached the V1 level.
Zhao, etc will be LDH together with ammonium polyphosphate for PVA flame retardant processing, the study found that when the adding amount of 15% of compound flame retardants, along with the content of LDH in 0.1% ~ 10% range gradually increases, the limit oxygen index for up to 33% and by level UL94V0, compared with the PP/ammonium polyphosphate, LDH join improve the decomposition temperature and mechanical properties of the system.
Zhang studied such as containing different divalent cations of LDH synergistic flame retardant PP/expansion type flame retardant system, results showed that the LDH can reach nanoscale dispersion in the system, coordination between LDH and ammonium polyphosphate flame retardant effect, increase the limit oxygen index of material, heat release rate, total heat release quantity and smoke production quantity to decrease, especially containing zinc 2 + and Cu2 + system of LDH make limit oxygen index reached 33%, UL94 testing by level where V0. LDH can significantly improve the thermal stability of the flame retardant system and form a more solid carbon layer.
