(1) heat-absorbing action.There is the fire retardant of high heat capacity, at high temperature undergo phase transition, dewater or the endothermic reaction such as dehydrohalogenation, reduce the temperature of fibrous material surface and flame zone, the speed of the heat scission reaction that slows down, suppress the generation of imflammable gas.
(2) covering protection effect.After fire retardant is heated, form glassy cover layer in fibrous material surface melting, become a barrier between condensed phase and flame.Both the diffusion of starvation, prevention imflammable gas, can stop heat transfer and heat radiation again, reduce the heat feeding back to fibrous material, thus suppress thermal cracking and combustion reaction.
(3) gas dilution effect.Fire retardant endothermic decomposition discharges the non-flammable gases such as nitrogen, carbon dioxide, sulfur dioxide and ammonia, makes the imflammable gas concentration of fibrous material cracking place be diluted to below combustion limits.Or make the oxygen of subregion, flame kernel place not enough, stop burning to continue.In addition, this non-flammable gases also has radiating and cooling effect.Their fire retardation size order is: N2>CO2>SO2>NH3.

(5) gas phase is fire-retardant.Add a small amount of inhibitor, catch lightweight free radical and hydroperoxyl radical in a large number at flame zone, reduce number of free radical, thus suppress or interrupt the chain reaction of burning, play fire retardation in gas phase.Gas phase fire retardation is insensitive to the chemical constitution of fibrous material.
(6) skin effect of particulate.If be mixed with a certain amount of inert particulate in fuel gas, it can not only absorb the combustion heat, reduce flame temperature, and, understand as wall of a container face, on the surface of particulate, high-energy hydroperoxyl radicals a large amount of during gas-phase combustion is reacted, be transformed into low-energy hydroperoxy radicals, thus suppress gas-phase combustion.
(7) molten drop effect: some thermoplastic synthetic fiber, as polyamide, polyester, shrinking molten drop when heating, reducing with the contact area of air, molten drop even occurs and falls and leave burning things which may cause a fire disaster, make burning be subject to certain obstruction.
According to existing result of study, the mechanism of fire retardation has physics, and also have chemistry, and the flame retardant effect of fiber provided by the invention is the compound of these mechanisms of action, reaches permanent fire retardant, limited oxygen index Loi is greater than more than 26.Not melting when this fiber is met fiery, low cigarette does not discharge poison gas, and itself flame does not occur, and leaves flame, self-extinguish.
