Red phosphorus synergistic flame retardant
Phosphor flame retardant is divided into organophosphorus flame retardant and inorganic phosphorus flame retardant. Organic phosphorus flame retardants mainly include triphenyl phosphate, three toluene phosphate ester, phosphate ester, the toluene diphenyl phosphate ester, phosphate, propyl benzene phosphate ester, styrene butadiene, and three phosphate ester, the commonly used inorganic phosphorus flame retardants have cooperation red phosphorus flame retardants, phosphate flame retardants, flame retardant, ammonium polyphosphate ammonium phosphate flame retardants, phosphate flame retardants, such as salt.
Wang, such as using Fourier transform infrared spectrometer, pyrolysis gas chromatograph, TGA, etc. The study of red phosphorus flame retardants together, red phosphorus Mg (OH) 2 flame retardant LLDPE together, the results showed that red phosphorus and Mg (OH) 2 is not only to increase the thermal stability of oxygen LLDPE, and molecular weight of the product of LLDPE chain rupture also are high.
Red phosphorus co-flame retardant is red to fuchsia powder, because it contains phosphorus only, so red phosphorus is more effective than other phosphorus compounds. According to the literature, the flame retardant level of HDPE with 8% red phosphorus can reach UL294V20.
However, red phosphorus also has the incompatibility with polyethylene resin, easy to absorb wet, color too deep, easy to produce phosphating hydrogen poisonous gas and so on. In order to overcome the above shortcomings, it is common to carry out coating or microencapsulation of red phosphorus. After microencapsulation of red phosphorus, it can improve its compatibility with resin and reduce its moisture absorption.
The materials used for red phosphorus coating include melamine resin, melamine formaldehyde resin and polyvinyl alcohol. According to reports in the literature of science and technology of China university of fire science national laboratory research cooperation with anhui province chemical industry research institute of red phosphorus in the surface of the red phosphorus microcapsules form dense film after drying, compared with ordinary red phosphorus, red phosphorus microcapsules in ignition, hygroscopicity has improved significantly.
In this paper, the PLDPE was first treated by the argon plasma, and then the same polarity maleic anhydride grafted pldpe2mah was then added to the phosphor flame retardant and the oxygen index was tested. The experimental results showed that when the addition of flame retardants was 32% (wt), the LOI was 3415, and the increase of LOI was increased with the increase of the grafting ratio in the condition of the same amount of flame retardant.

Tris (2-Chloroethyl) Phosphate
Product Name: Trichloroethyl Phosphate Flame Retardant Plasticizer; Tris (β-Chloroethyl) Phosphate; Bis (2-Chloroethyl) Phosphate With 2-Chloroethyl Phosphate; Tris (β-Chloroethyl) Phosphoric Acid Ester; Tris (2-Chloroethyl) Phosphate; TCEP; Trichloroethyl Phosphate
CAS RN: 115-96-8
EINECS Number: 204-118-5
Molecular Formula: C6H12Cl3O4P
Molecular Weight: 285.4898
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 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%.
In conclusion, although phosphorus-containing flame retardant flame retardant effect is better, but as a result of phosphorus-containing flame retardants are mostly poor water resistance, and with the compatibility of polyolefin also is bad, lead to poor mechanical properties of flame retardant products, is currently used in polyolefin material is not too much.
The most commonly used metal compound flame retardant is Sb2O3 (ATO). It is used alone, and the flame retardant effect is generally not classified as flame retardant. It is commonly used with other flame retardants, such as halide, and has excellent flame retardant effect and smoke suppression effect. Therefore, it can be used as the flame retardant of halogen flame retardant. Furthermore, the finer the granularity of Sb2O3, the better the flame retardant effect, and the less addition of Sb2O3. Due to the high price of Sb2O3, Sb2O3 substitutes have been developed in recent years, such as zinc borate, zinc oxide, iron oxide, tin oxide, zinc tin and zinc hydroxytin, etc.
Metal boride is commonly zinc borate hydrate, in 290 ~ 450 ℃ will release 1315% water of crystallization, and absorb heat 503 j Π g. As a flame retardant, it can be used alone as a cheap alternative to Sb2O3. The same as Sb2O3, the flame retardant effect is not good when acting alone, and it is usually joined with other flame retardants.
Expansion flame retardant (IFR) is not a single flame retardant varieties, but phosphorus, nitrogen, carbon as the main composition of composite flame retardant, halogen-free, it does not contain halogen, also don't use Sb2O3 do association effect agent, its system have synergy within itself. Since such flame retardants are foamed at the heat, they are called expansibility flame retardants.
Contain expansion flame retardant plastic surface will be generated when burnt carbon foam, insulation, oxygen, smoke suppression and prevent the effect, such as melt dripping with excellent flame retardant properties, and halogen free, low smoke, low toxic and anti dripping and non-corrosive gases, in line with the future development direction of flame retardant, has the very broad prospects for development.
