Flame retardant and flame retardant technology
Plastics and their products are more flammable. In order to reduce the occurrence of fire, some flame retardants are added to the plastic to improve their fire-resistance. Compared with other auxiliaries, the development and application of flame retardants have been slightly delayed, but the development of flame retardants has been very fast, and some countries have been second only to plasticizers. Therefore, the study of flame retardant and flame retardant technology has become a very important subject.
With the application of modern high science and technology, the old fire retardants and fire retardant technology has far cannot satisfy the market demand for its performance, such as containing halogen flame retardants in material burns out large amounts of hydrogen halide gas, and water to form a strong corrosive halogen acid and cause the secondary pollution.
Nowadays the halogen-free flame retardant for mounting, containing halogen flame retardants are hard to get greater development in the 21st century, and the inorganic flame retardants containing combined water, such as Al (OH) 3, such as Mg (OH) 2 will be to develop in the direction of ultra-micronization model.the and nano, single flame retardants will be replaced by composite has a synergistic effect of flame retardant, new type of fire retardants and fire retardant technology of the 21st century will be, high efficiency, low smoke, low toxicity and versatile.
In high temperature, flame retardants form condensed phases on the surface of the polymer, isolating the air, preventing heat transfer and reducing flammable gas release, thereby achieving the flame retardant purpose. Form condensed phase isolation film in one of two ways: one is the flame retardants in combustion temperature are divided into the vitreous non-volatile substances, is coated on the surface of polymer, the dense layer have the effect of the isolation membrane, such as boron and halogenated phosphate flame retardant with similar characteristics;
The second is using thermal degradation products of flame retardant to boost the dehydration of the polymer surface, carbide form carbide layer, using the elemental carbon does not produce evaporation and decomposition combustion flame, flame retardant protective effect, such as phosphorus flame retardant flame retardant effect of oxygen containing polymer.
In polymer combustion process, a large number of free radicals generated promote gas phase combustion reaction, such as managed to capture and eliminate the free radicals, cut off the free radical chain reaction, can control the combustion, thus achieve the goal of flame retardant. The flame retardant mechanism of halogen flame retardant is of this kind.

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.
Heat absorption dehydration, phase transformation in the flame retardants, decomposition, or other endothermic reaction, lower the temperature of the polymer surface and the burning area, to prevent thermal degradation, thus reduced the amount of volatile combustible gases, ultimately destroy the sustain continuous combustion conditions, polymer flame retardant. Al(OH)3 and Mg(OH)2 and boron inorganic flame retardants are representative.
The existing flame retardant can be recombined to make the mechanism of various effects to reduce the amount of flame retardant and to improve the flame retardant effect. Such as antimony oxide and organic halide cooperative use of flame retardant and can form a very effective flame retardant system, on the combustion of fuel, the organic acid or halogen halide release hydrogen, antimony and antimony oxide reaction to produce three halide or antimony acyl halide (SbOX) will, flame retardant effects of these antimony compounds, including product SbX3 flame retardant effect is very big, it can form an inert gas, reduce fuel contact with oxygen, carbon layer formation; At high temperature, SbX3 volatilizes into the flame and breaks down into various antimony compounds and halogen free radicals, which change the chemical properties of the flame and consume the energy of the flame, thereby achieving the flame retardant purpose.
Organic phosphorus flame retardants is with phosphorus-containing flame retardants and organic fire retardant agent, many varieties, wide application, in the early 1970 s, organic phosphorus flame retardant of organic fire retardant agents on the market in the United States has accounted for more than 50% of total sales.
At present, the main applications are phosphatates such as isodecyl diphenyl phosphate, 2 ethylhexyl diphenyl phosphate phosphate triisopropyl phenyl ester, etc. Phosphonates, such as dichloroethyl phosphonates; Salinity, ethylene diethylene (2 cyanoethyl); Diethyl phosphonates containing phosphors and polyols such as N, N pairs (2 hydroxyethyl).
