Composite flame retardant
The halogenated flame retardants used in compound flame retardants are only used in the research of polyolefin flame retardant. Also used alone Sb2O3 on the flame retardant performance not only no great contribution can make system instead of the mechanical properties decreased a lot, because both joined showed synergistic effect, usually think halide in synergy with Sb2O3 reaction, thus significantly improve the flame retardant effect of a phosphorus-containing flame retardant, because they can when burnt in a wide range of temperatures generated SbX3, and SbX3 can effectively capture free radicals. It is reported that SbCl3 and SbBr3 are used directly for polyolefin flame retardant, which is better than halogen flame retardant and Sb2O3.
Zhi-yu bao, such as by DBD, chlorinated paraffin, Sb2O3, ZnO composite flame retardant synergistic flame retardant HDPE and the formulation of the optimization design is made when DBD, wax chloride fossils, Sb2O3 dosage respectively in 3, the dosage of ZnO is one the best effect, the oxygen index of the HDPE can reach 2911, the tensile strength can be up to 25 mpa.
ROM built on ten bromine biphenyl ether, Sb2O3 synergistic flame retardant composite flame retardant HDPE research: adding 14% of ten bromine biphenyl ether and 6% of Sb2O3 can make HDPE level V20, moreover HDPE mechanical properties can keep ideal result: the tensile strength of 2119 mpa, the elongation at break was 305%, the notched impact strength was 30 kj Π m2. And he use Al (OH) 3 instead of partial DBDPO Π Sb2O3 (400 mesh), it is concluded that 10% of Al (OH) 3 (1200 mesh) can replace 3% DBDPO Π Sb2O3 (400 mesh).
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%.
The study was conducted on the synergistic Sb2O3 flame retardant PE of decabromodiphenyl ethane. Concluded that DBDPE Π Sb2O3 joining can reduce PE combustion heat release rate, when the addition amount of 30% oxygen index of PE for more than 28, DBDPE Π Sb2O3 composite flame retardant can well restrain melt dripping phenomenon of PE, the mechanics properties of the system are as follows: from 11 mpa to 917 mpa tensile strength, impact strength from 75 kj Π m2 reduced to 15 kj Π m2.
Liu Xiongxiong use ten bromine biphenyl ether Π Sb2O3 synergistic flame retardant PE, when ten bromine biphenyl ether dosage for 7 sets, Sb2O3 dosage of 4 of the oxygen index of the system can reach more than 4712, in addition the author also used glass fiber system has been enhanced processing, make the mechanical properties of system a lot of ascension, the tensile strength has never before modification of 34 mpa to 61 mpa, impact strength, never before modification of 245 j Π m increased to 375 j Π m.
Multi - compound flame retardant system. Carpentier, such as using EVA2Mg (OH) 2 Π zinc borate polyethylene for the study of flame retardant. According to the experiment, the degradation process of polyethylene was slowed down by zinc borate, and a glass protective layer could be formed to isolate the polyethylene molecular chain in the inner layer from the heat source.
Chun-ming tian of expanded graphite synergy APP flame-retardant HDPE was studied, it is concluded that adding EG Π APP HDPE after thermal stability increased, slow degradation, carbon residue content increased. When the APP: EG= 2:1, the oxygen index of the system is up to 30, and the flame retardant effect is achieved, and the tensile strength of the system is not much lower, from 1417MPa to 1310MPa.
Bourbigot et al. Molecular sieve as APP Π PER expansion system of effective agent when the optimum dosage is only 1 wt %. Tian chunming and other experiments demonstrated that ZnO can also play the role of coagent in the swelling flame retardant. The optimal dosage is about 1, but it can lead to the decrease of oxygen index in excess. ZnO's co-effect is to catalyze the esterification and carbonization reaction to generate more residual carbon and form stable protective carbon layer.
Zhi-long zhang, expansion flame retardant synergistic flame retardant PE Π zeolite. According to the study, the APP: PER: ZEO= 2115:6:215 is the best result, and the oxygen index of the material can reach 2913.
