Flame retardant efficiency of flame retardant
The flame retardant mechanism of chlorine flame retardant is the same as that of bromine flame retardant. In terms of flame retardant efficiency of flame retardant, the chlorine flame retardant is much less than that of bromine flame retardant.
(1) chlorinated paraffin. Chlorinated paraffin chloride is 70 % chlorinated paraffin is a white powder and has no chemical stability. It is not soluble in water and low level alcohol at normal temperature. Chlorine content is 52% of chlorinated paraffin is oily liquid, plays a role of flame retardant in gas phase. Chlorinated paraffin and antimony trioxide used cooperatively, usually because of its low price, and the plasticizer of good performance, particularly applicable to consider the cost and the processability of the product, this is the best of the flame retardant chemical formula, suitable for hard and soft products. But chlorinated paraffin is not easy to add, otherwise it is easy to spill.
(2) double (hexachlorocyclopentadiene) cyclooctane. The goods is a kind of additive flame retardant, formula for C18H12Cl12. The advantages of the goods very much, such as good initial color, excellent electric properties, good flame retardant performance, high thermal stability, low smoke and selectivity of association effect agent, good ultraviolet resistance, resistance to hydrolysis performance good, non-toxic and so on.
Phosphorus flame retardant is not a new flame retardant, but it is very popular in the field of flame retardant as a non-halogen system. Moreover, the flame retardant efficiency of phosphorus is excellent. The flame retardants of organophosphorus include phosphonates, phosphonates (including halogenated derivatives), phosphonates, phosphine, phosphorus polyols/nitrides, etc. But as a flame retardant, the most widely used are phosphates and phosphonates, especially phosphonates containing halogen. Phosphate and phosphate ester containing halogen flame retardants and plasticizers functions concurrently, give priority to with flame retardant, called increase plastic flame retardant; rather than the main function of halide phosphate is plasticizing, both flame retardant effect, known as the flame retardant plasticizer.
(1) flame retardant mechanism. The flame retardant mechanism of phosphorus flame retardant is not single. It is generally believed that the flame retardant of organophosphorus system can play flame retardant in coagulation phase and gas phase. However, the flame retardant mechanism is different from the structure, polymer type and combustion condition of the flame retardant.
1. Flame retardant mechanism of condensed phase. When a polymer containing phosphor flame retardant is heated, it can be decomposed into phosphoric acid or polyphosphoric acid. These acids catalyze the absorption of hydroxyl compounds into carbon reactions, producing water and coke. The carbonization of hydroxyl compounds results in the formation of a graphite-like coke layer on the surface of the carbon layer. The carbon layer is separated by oxygen and heat insulation, which can suffocate the combustion, thus achieving the goal of flame retardation.
Tris (2-Chloroethyl) Phosphate 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 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%.
2. Flame retardant mechanism of gas phase. The product of thermal decomposition of organophosphorus flame retardants contains PO. The free radicals are using OH. Free radicals, so that the H in the flame. And OH. The concentration is greatly reduced to inhibit the combustion.
Main varieties of phosphor flame retardant
1. 3 (alpha ethyl chloride) phosphate ester 3 (alpha ethyl chloride) phosphate ester (TCEP) for adding flame retardant agent, molecular formula for C6H12O4Cl3P. 3 (alpha ethyl chloride) phosphate ester is colorless transparent liquid, insoluble in fat hydrocarbon, slightly soluble in water. 3 (alpha ethyl chloride) phosphate ester has excellent flame retardant, good low temperature resistance and resistance to uv linear. Its vapor can only be ignited by a direct flame at 225 degrees and then self-extinguishing after the flame is removed. With TECP as flame retardant, it can not only improve the flame retardant level of flame retardant materials, but also improve its water resistance, acid resistance, cold resistance and anti-static property. TECP USES 10% to 20% in flame retardant unsaturated polyester, and 5% to 10% in soft PVC as auxiliary plasticizer.
3 (1, 3 chloro-2-propyl) ester phosphate (1, 3 chloro-2-propyl) ester (1, 3 chloro-2-propyl) ester (TDCPP) is a type of added flame retardant, and the molecular formula is C9H15O4CL6P., and the amount of the addition in soft PVC is not more than 15%.
3. Phospholipides are the main products of the two phenyl phosphates (TPP) and diphenyl phosphite (DPIOP).
The flame retardant of expansive flame retardant is very good. It is a flame retardant with phosphorus nitrogen as its main component. It does not contain halogen, and it does not use antimony oxide as coefficent agent. Contain when heated, the surface of the expansion type flame retardant polymer can generate a uniform layer of carbon foam layer, the foam layer heat insulation, lie between oxygen, smoke suppression and can prevent molten drop, to form a good flame retardant performance.
