There is no halogen green flame retardant
Bromine flame retardants are harmful to ecological safety due to toxicity, and the United States and Europe have introduced regulations to disable some varieties. The flame retardant of bromine is banned due to the toxicity and combustion of toxic gases and a large amount of smoke. It is imperative to develop a halogen free flame retardant without bromine, low toxicity and smoke suppression.
Flame retardants, meanwhile, more strict laws and regulations also require the use of high thermal stability, low heat release rate, smoke less, low toxicity and efficient flame retardant, research hot spot when push halogen-free environment-friendly flame retardants, halogen-free, environmentally friendly flame retardant has pushed into the market of phosphorus - nitrogen inflating and phosphorus - nitrogen elemental expansion type two kinds big.
The activity of bromine flame retardant is based on thermal decomposition to generate free radicals. In the free radical chain reaction of the combustion process, the bromine free radicals can act as scavengers. Obviously, other free radical sources can be used as synergistic agents according to the mechanism of this action. These free radical sources mainly include unstable carbon-carbon, oxygen-oxygen, nitrogen-nitrogen bond.
Phosphorus-containing flame retardants are mostly in the solidification phase play flame retardant effect, including inhibition of flame, heat melt flow, containing phosphoric acid to form the surface of the barrier, and acid catalytic into carbon, carbon layer heat insulation, lie between oxygen and so on.
Phosphoric acid was decomposed at lower temperature when phosphoric acid flame retardant cellulose fiber was decomposed. Its strong dehydration forces the carbonization of cellulose and inhibits the formation of combustible cellulose pyrolysis, thereby achieving the flame retardant effect. Phosphorus compounds also prevent carbon dioxide from being oxidized to carbon dioxide, thus reducing oxidative heat release.
In rigid polyurethane foam plastics, phosphorous flame retardant can promote carbon and flame flame retardant. But in soft polyurethane foam, only a small amount of carbon can be formed, not enough to insulate the oxygen. In PET, phosphorous flame retardant can prolong the volatile combustible after the combustion of PET, and then weaken the acid catalyzed by the PET, thus promoting the carbon.

Diphenyl Isooctyl Phosphate (S141,362, DPOP) Product Overview
Chemical Classification: Diphenyl Isooctyl Phosphate, Diphenyl 2-Ethylhexyl Phosphate
Diphenyl Isooctyl Phosphate (S141,362, DPOP) Is An Excellent Flame Retardant Plasticizer That Can Be Used In Most Industrial Polymers Including PVC And Its Copolymers, Nitrocellulose, Ethylcellulose, Poly Methyl Cellulose Methyl Ester, Polystyrene And The Like. Diphenyl Isooctyl Phosphate (S141,362, DPOP) Are Generally Used In The Manufacture Of Vinyl Sheets, Coated Fabrics, Inks, Plastics, Rubber And Plastic Foamed Organic Sol, Adhesives, Vinyl And Conveyor Belts. Due To Excellent Solubility, Improve The Performance Of Many Formulations. In Addition, It Can Be The Final Product It Offers The Following Range Of Interesting Properties Such As Flame Retardancy, Low Temperature Flexibility, Abrasion Resistance, Grease Resistance, Excellent Light Stability And Outdoor Weather Resistance And Excellent High Screen Welding Performance. Due To Its Excellent Solubility, Diphenyl Isooctyl Phosphate (S141, 362, DPOP), And Then 3 Phr Of Bismuth Oxide And 10-20 Phr Of Aluminum Hydroxide Were Added.
Diphenyl Isooctyl Phosphate (S141,362, DPOP) Can Be Used As An Excellent Flame Retardant Material For Transparent Films. In Some Fire-Resistant Harsh Colored Films, It Is Recommended To Add Diphenyl Isooctyl Phosphate (S141,362, DPOP) To Significantly Improve The Light Stability And Outdoor Weather Resistance Of The Film.
(S141,362, DPOP) With Diphenyl Phosphate And Tricresyl Phosphate In The Presence Of 10-15% Of Phthalate Plasticizer Such As DOP, Phosphoric Acid Diphenyl Isooctyl Ester (S141, 362, DPOP) Allows The Resulting Plastic To Have A Low Initial Viscosity And A Good Good False Plasticity And Storage Stability. Due To Its Good Pseudoplasticity And Film-Forming Properties It Is Recommended To Add Diphenyl Isooctyl Phosphate (S141,362, DPOP) To PMMA-Based Plastics And Nitrocellulose Coatings And Inks.
In order to effectively play the carbon effect of phosphorus flame retardant, an important method is to combine the hydrogen with hydrogen. Some nitrogen compounds can enhance the flame retardant effect of phosphorus compounds on cellulose, because these two compounds react to produce a substance with p-n bonds, which has a stronger flame retardant effect than phosphorus compounds. Nitrogen-nitrogen compounds can enhance phosphorus oxidation and release inert gases such as ammonia.
No halogenation is a development direction of flame retardant, which is used for flame retardant of high polymer such as fiber and plastic.
For nearly 10 years, about the research and development of the expansion type flame retardant IFR very much, mainly using phosphorus - nitrogen series, through the flame retardant system of the synergy of acid source, carbon source, gas source form the expansion of the carbon layer, so as to cut off the molten polymer and combustible gases, and help the molten polymer into carbon, reduce the generation of combustible gases; Subsequently, as the combustion progresses, the expanded carbon layer is gradually formed and the expanded carbon layer has good thermal insulation function and strength.
IFR is mainly used to inhibit the pyrolysis of materials in solidification phase, and to reduce and interrupt the source of combustible materials. When the material is burnt, the porous carbon layer is formed to insulate and prevent the gas from entering the gas phase. The flame retardant is heated by heat decomposition, which prevents the temperature of flame retardant material from rising to thermal decomposition temperature.
IFR including acid source, carbon source and gas source, and their interaction to form carbon layer: under low temperature (150 ℃), containing phosphoric acid source can be used as dehydrating agent acid; At a slightly higher temperature, the acid reacts with the carbon source, the nitrogen in the system ACTS as the catalyst for the esterification reaction and accelerates the esterification reaction. The water vapour generated during the reaction process and the non-combustible gas produced by the gas source cause the system in the molten state to expand foaming. At the same time, carbon source and ester are dehydrated and carbonized, and the system is expanded and foamed, and the final system is solidified to form a porous carbon layer.
In the IFR three components, the acid source is the most important, and it is the largest proportion in the triplicate. Since the main components are in the acid source, the acid source alone can be called the flame retardant, while the carbon source and the gas source are called coactive agents. The flame retardant efficiency of monic acid source is not high, but it is obviously improved with the addition of coagent.
