Flame retardant synergistic effect
In recent years, the world has not developed a fundamental new flame retardant system. However, research groups around the world have made great progress in promoting the development of existing flame retardants to the halogen-free system.
Although the flame retardant synergistic effect mechanism is still not fully grasp, but the preparation of flame retardant additives and flame retardant synergistic effect using multifunctional flame retardant system is becoming more and more popular, and is likely to be the important features of the future development of flame retardants.
At the technology of flame retardant, flame retardant synergistic effect not only produce more effective flame retardant system, but also reduce the use amount of other flame retardants in chemical reagent makes possible, and to improve the flame retardant efficiency of flame retardant in order to meet the increasingly stringent flame retardant production and use of standards make a positive contribution.
Many minerals have synergistic effects with organic halogen flame retardants and organophosphorus flame retardants. Synergistic response can be observed in thermosetting materials composed of borates and hydrated minerals. Adding inorganic mineral filler to the expanded fireproof material can better control the shape of the fireproof material in the expansion structure after contacting the flame. More and more experience has shown that although the inorganic mineral filler apparent prices are on the increase, but in fact, add the appropriate inorganic mineral filler flame retardant can reduce lots of other active additives or by providing multi-functional performance to reduce the production cost.
At present, the most important synergistic flame retardant compounds are antimony oxide and halogen donor compounds. The application prospect of metal oxide and other metal compounds is also promising, especially in plastic engineering. Another important development direction of flame retardant technology is to mix the new type of antimony oxide into granule as a synergistic flame retardant.
Antimony oxide mixtures have a single component flame retardant system and the advantages of the parent grain. The cost of antimony compounds is relatively inexpensive and has been heavily used as a flame retardant. Antimony is a kind of toxic material, however, its use in most countries are restricted by the relevant laws and regulations, so there is a kind of gradually replacing antimony compound flame retardant or reduce the trend of the use. But antimony compounds have a good synergistic effect with halogenated flame retardants, especially for plasticized polyvinyl chloride resin. A suitable bromine or chlorine compound is needed to obtain a certain flame retardant property for a non-halogen polymer.
Trixylyl Phosphate(TXP)

Density: 1.154g / Cm3
Flash Point: 263.8 ° C
Refractive Index: 1.550? 1.560
Color Value: (PT-CO) ≤200
Refractive Index: N20 / D 1.552
Boiling Point: 490.8 ° Cat760mmHg
Raw Materials: Xylenol, Phosphorus Trichloride, Chlorine Through Esterification, Chlorination, Hydrolysis, Distillation Steps To Get.
Packing: Net Weight 200KG / Galvanized Iron Drum (A Small Cabinet Playing With 16 Tons), 1000KG / IB Bucket (A Small Cabinet 18 Tons) Or 23 Tons ISOTANK.
Trixylyl Phosphate(TXP) Use
Phosphate Trisphenylene Phosphate Is Low, Resistant To Hydrolysis, Good Flame Retardant Can Be Used As Vinyl Resin, Cellulose Resin, Natural And Synthetic Rubber Plasticizer, Low Volatility, Good Water Resistance, Flame Retardant. Trichenylene Phosphate Use For Use In Combustible Turbine Oils, With Good Flame Resistance And Good Thermal Oxidation Safety, Good Lubricity, Extreme Pressure Antiwear Additives For Lubricants, Thickeners. Also Used For Fire-Resistant Turbine Oil, With Good Thermal Oxidation Stability, Lubricity, As A Lubricant Anti-Wear Additives, Plasticizers, But Also For Flame Retardant, Wear-Resistant, Resistant To The Mold Of The Cable, Ethylene Conveyor Belt, Artificial Leather, Foam, Flooring Materials, But Also In Metallurgy, Electricity, Mechanical Engineering And Other Aspects As A Fire-Resistant Hydraulic Oil.
Of many alternatives to antimony compounds, zinc sulfide is the most potent. As of now, zinc sulphide is only considered as a pigment for the pigment "target ="_blank ">. Zinc sulphide alone or as a new flame retardant for synergistic compounds has been developed.
Adding melamine to inorganic mineral filler preparation into composite flame retardant, flame retardant and mixed preparation of composite flame retardant polypropylene, it is usually possible to improve the flame retardant UL94 flame retardant test behavior, but also can eliminate single use of inorganic mineral filler generated afterglow phenomenon.
The compound flame retardant can also reduce the quality of flame retardant polypropylene, thus producing economic benefits. They also allow the use of relatively cheap inert fillers, such as high territory and talc, which do not exhibit flame retardant properties when used alone.
In the use of brominated flame retardants, part can replace with inorganic mineral filler, can improve the system of some mechanical properties, may also increase transparency and reduce the corrosion of combustion generated when the smoke, thus reduce the potential harm to the environment. Especially coating of magnesium hydroxide and aluminum hydroxide can greatly improve the flame retardant performance and reduce smoke release level, allowed to sharply reduce additive usage, and won't sacrifice performance flame retardant and smoke suppression characteristics.
Boric acid salt is a new kind of synergistic flame retardant for halogen retardant and halogen-free flame retardant. Although it has long been known that borates have synergistic effects, the general use of antimony trioxide has left the use of borates in the cold.
Brominated hydrogen bromide is formed when bromide flame retardants are burned, and hydrogen bromide can, in turn, terminate the free radicals produced by the flame, thereby further inhibiting the flame. Some flame retardants treated thermoplastic plastic combustion produced droplets or soot drop, and borate can effectively contain the development trend of this situation.
