Description
Technical field
The present invention relates to a kind of functional aid of combustible polymers, particularly, relate to a kind of fire retardant.
Background technology
Fire retardant claims again incombustible agent, flame-proofing agent or fireproofing agent: the functional aid of giving combustible polymers flame retardancy; According to application mode, be divided into additive flame retardant and reactive flame retardant.According to composition, additive flame retardant mainly comprises inorganic combustion inhibitor, halogenated flame retardant (organic chloride and organic bromide), phosphorus flame retardant (red phosphorus, phosphoric acid ester and halogenated phosphate etc.) and nitrogenated flame retardant etc.
Fire retardant mainly contains organic and inorganic at present, halogen and non-halogen.Organic is to take some fire retardants that bromine system, phosphorus nitrogen system, nitrogen system and red phosphorus and compound be representative, and inorganic is mainly the flame-retardant systems such as antimonous oxide, magnesium hydroxide, aluminium hydroxide, silicon system.Fire retardant is brought into play its fire retardation by some mechanism, as heat-absorbing action, covering effect, suppress the smothering action of chain reaction, non-flammable gas etc.Most fire retardants are to reach fire-retardant object by some mechanism actings in conjunction.
1, heat-absorbing action
Any burning is limited at shorter time institute's liberated heat, if can absorb a part of heat that burning things which may cause a fire disaster is emitted in the shorter time, flame temperature will reduce so, be radiated burning surface and act on the heat that the flammable molecule having gasified is cracked into free radical and will reduce, combustion reactions will obtain inhibition to a certain extent.Under hot conditions, there is strong thermo-negative reaction in fire retardant, absorbs the part heat that burning is emitted, and reduces the temperature on combustiblematerials surface, effectively suppresses the generation of inflammable gas, stops spreading of burning.Al (OH)
3the fire retardant mechanism of fire retardant is exactly by improving the thermal capacitance of polymkeric substance, making it absorb more heat before reaching heat decomposition temperature, thereby improve its flame retardant properties.When this based flame retardant is given full play to it in conjunction with water vapor, a large amount of thermal properties of inhaling, improve the fire retardancy of himself.
2, covering effect
In combustible matl, add after fire retardant, fire retardant at high temperature can form glassy or stable foam tectum, and starvation has the effect that heat insulation, oxygen barrier, prevention inflammable gas are outwards overflowed, thereby reaches fire-retardant object.While being heated as organic resistance phosphorus type flame retardant, can produce structure more stable crosslinked shape solid matter or carburization zone.The formation of carburization zone can stop the further pyrolysis of polymkeric substance on the one hand, can stop on the other hand its inner thermolysis to produce thing and enter gas phase participation combustion processes.
3, suppress chain reaction
Theoretical according to the chain reaction of burning, maintain burning required be free radical.Fire retardant can act on gaseous combustion district, catches the free radical in combustion reactions, thereby stops flame transmission, and the flame density of combustion zone is declined, and finally makes combustion velocity decline until stop.As halogen containing flame-retardant, its vaporization temperature is identical with polymer unwinds temperature or close, and when polymkeric substance decomposes, fire retardant also evaporates simultaneously.Now halogen containing flame-retardant and thermal decomposition product are simultaneously in gaseous combustion district, and halogen just can catch the free radical in combustion reactions, thereby stop flame transmission, and the flame density of combustion zone is declined, and finally make combustion velocity decline until stop.
4, non-flammable gas smothering action
When fire retardant is heated, decomposite non-flammable gas, the concentration of the inflammable gas that combustiblematerials is decomposed out waters down below burning lower limit.Also the oxygen concn in combustion zone is there is the effect of dilution, stop proceeding of burning, reach fire-retardant effect simultaneously.
But, current many public places are as hotel, hotel, Internet bar, the escape after fire is only noted and sues and labours there is no to note the obviate to these occasions by film theater Deng He family, the inflammable substance in these occasions are carried out to fire-retardant finish, allow these inflammable substance be difficult to burning, thereby accomplish prevention or delay fire, give afterwards sue and labour and escape leaves the quality time.
