Research on flame retardant of textiles
According to statistics, about 20% above the fire accident in the world are caused by textile burning or expanded, especially residential fire caused by textile spread of fire or fire accident ratio is bigger. Therefore, the flame retardant function of textiles is important to eliminate fire hazards and delay the spread of fire, thus reducing the loss of life and property of the people.
The study of flame retardant of textiles started in industrial developed countries. Many industrial developed countries have formulated the corresponding standards of textile fire retardation and testing methods; In some countries, the flame retardant performance standards of textiles are also enforced by relevant laws. With the development of city modernization, the development of tourism, transportation, national industrial and research departments are racing to the flame retardant of textiles research to meet the needs of the flame retardant textiles continuously expanded, and form the fierce competition in the international market, thus to promote the development of the flame retardant of textiles research.
After the so-called "fire", is not flame retardant finishing of textiles in contact when the fire will not burn, but to make the fabric in the fire can minimize its flammability, slowing the rate of spread and does not form a large area burn, and left after the fire, can quickly self-extinguishing, no longer burning or smoldering. The flame retardant is closely related to combustion.
The latest idea is that combustion should have four elements -- fuel, heat, oxygen, chain reaction. And usually fabric combustion can be divided into three stages, namely, thermal decomposition, thermal ignition, heat, on the four elements of different combustion stage adopts corresponding flame retardant resisted, has formed a variety of flame retardant mechanism of flame retardant mechanism and interrupt. According to the existing research results, the flame retardant mechanism can be divided into the following types.
(1) endothermic reaction: except heat. Has a high heat capacity of the flame retardants, phase change at high temperature, dehydration, or dehydrohalogenation endothermic decomposition reaction, reduce the temperature of fiber surface and flame area, slow down the speed of the thermal cracking reaction, inhibiting the production of combustible gas.
(2) the formation of free radicals, flame retardant heat into gas, the gas in the fire area of capture free radicals, hydroxyl radicals and hydrogen energy reduce their concentration, thus inhibiting or interrupt the combustion chain reaction, play a role of flame retardant in the gas phase.

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.
(3) melting theory: under the action of heat and energy, flame retardant into molten state, the fabric surface impermeable layer, become a barrier between the condensed phase and the flame, can stop the heat conduction and thermal radiation, reduce the heat feedback to the fiber, thus inhibiting pyrolysis and combustion reaction.
(4) particle surface effect: if mixed with a certain amount of inert particles in the combustible gas, it not only can absorb heat of combustion, reducing flame temperature, but also on the surface of particles in the gas phase combustion reaction of hydrogen energy free radicals, shift into low energy of hydrogen oxygen free radicals, thereby inhibiting gas phase combustion.
(5) generate the non-combustible gas: flame retardant endothermic decomposition release nitrogen, carbon dioxide, sulphur dioxide and ammonia non-combustible gases, such as fiber material cracking of combustible gas concentration dilution to the burning under the limit; Or the oxygen in some areas of the center of the flame may not be sufficient to prevent combustion from continuing. In addition, the non-combustible gas has a cooling effect.
(6) flame retardant condensed phases: through the effect of flame retardant, in the condensed phase reaction area, change the fiber thermal cracking reaction process of macromolecular chain, has prompted dehydration, condensation, cyclization and crosslinking reaction, carbonization, to increase the coking residue, reduce the production of combustible gas, to play a role of flame retardant flame retardant in the condensed phase.
Since the molecular structure of the fiber and the type of flame retardants are different, the flame retardant function is very complicated and is not limited to the above aspects. In order to obtain the best flame retardant effect, the mechanism mentioned above should work together as much as possible, such as using synergistic effect.
