2017-9-22 11:46:04
Organophosphorus flame retardant is a kind of flame retardant, which is the same as halogen flame retardant. It has many varieties and is widely used. The halogen flame retardant has many disadvantages, such as the poor anti-uv stability, the burning of more smoke, corrosive gases and toxic gases.
The study found that the polybrominated diphenyl ether and its flame retardant polymer pyrolysis and combustion products contain carcinogenic substance four bromine generation of double benzene and two mouth 4-dioxane and tetrabromo coumarone, phosphorus-containing flame retardants is restricted, the use of non halogen flame retardants, especially the organic phosphorus flame retardants and development have become more important. Although organophosphate compounds have certain toxicity, teratogenicity but they is not high, its breakdown products and of the flame retardant polymer pyrolysis and combustion products of corrosive, toxic substances and seldom. Organic phosphorus flame retardants is a hotspot of research on flame retardant, but also because of organophosphorous flame retardants besides has the flame retardant performance, many varieties at the same time also has the plasticizing, thermal stability, and so on, to improve the comprehensive performance of high polymer material has a very important role.
Types, synthesis and application of organophosphorus flame retardants. At present, the organic phosphorus flame retardants in the research, development, every year there are many related literature reports, taken together, mainly for phosphate, phosphonic acid ester, phosphine oxide, phosphorus heterocyclic compound, research of condensed phosphate and organic phosphate, etc.
Phosphate flame retardant. Phosphate flame retardant is the main flame retardant of organophosphorus, which can be used in the flame retardant of polystyrene, polyurethane foam plastics, polyester, polycarbonate and liquid crystal. The flame retardants of phosphate ester include phosphoric acid ester flame retardant, nitrogen phosphate flame retardant and halogen phosphate flame retardant.
Phosphoric acid ester flame retardant. Most of the flame retardants are phenolic phosphate. It is reported that the following compounds can be used in flame retardant treatment of high - resistant polystyrene.
Phosphoric acid ester flame retardant. The phosphoric acid ester containing nitrogen has two kinds of elements, including nitrogen and phosphorus. The flame retardant effect should be better than that of only phosphorus containing phosphorus. Nitrogen phosphate flame retardants are mainly derived from amine, diamine and melamine in compounds. The preparation, properties and applications of nitrogen phosphate flame retardants with the following structures were reported by matsuhara. The compound has good thermal stability, compatibility, no frost, no color.
There are also many phosphate-containing phosphate-retardants in the source of melamine, which can be used in the flame retardant of high polymers such as PE.
Tris(2-chloroethyl)phosphate(TCEP)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%.
The halogen phosphate flame retardants are reported to be much less reported than before because of the corrosive gas and carcinogen caused by halogen after combustion of the flame retardant. However, there are still some reports on the high efficiency of the flame retardant, mostly phosphatates containing chlorine, bromine phosphate or high halogen content.
Phosphonate flame retardant. Phosphonates are also widely used as flame retardants. At present, the research of phosphonate esters is mainly focused on nitrogen phosphonates and reactive phosphonates. It is reported that phosphine phosphonate, which is produced by phosphate and cyanide reaction, has the effect of flame retardant and plasticizing. Phosphonates are commonly used as reactive flame retardants.
Phosphine flame retardants. The hydrolysis of phosphine is better than that of phosphate. Phosphine retardants are classified into two types: additive type and reactive type. Phosphine diethylene glycol can be used to make flame retardant polyester, polycarbonate, epoxy resin and polyurethane.
Phosphonate flame retardant. The phosphonate flame retardant is generally used as reactive flame retardant and has a stabilizing effect and is widely used in polyester flame retardant treatment. It can be used as flame retardant and heat stabilizer, and can also be used as flame retardant raw material for PET synthesis. These compounds are prepared by addition reaction.
Organic phosphorus heterocyclic compound flame retardant. Organophosphorus heterocyclic compounds are one of the most active fields in the recent study of flame retardants, and also a hotspot in the research of organophosphorus chemistry. This is mainly because the structure and synthesis of organophosphorus heterocyclic compounds have very important research value, and its application scope is constantly expanding. The flame retardant of organophosphorus heterocyclic compound has five rings, six rings and spiral ring compounds.
