Abstract
The invention discloses an application of an iron oxide in elimination of irritating odor in red phosphorus flame retardant nylon. The iron oxide is a mixed active iron oxide of ferroferric oxide and ferric oxide, by calculating according to 100 parts by weight of nylon, the adding quantity of red phosphorus is 10 parts by weight, the adding quantity of the iron oxide is 1-5 parts by weight, and when the three, namely nylon, a red phosphorus flame retardant and a deodorant, are uniformly mixed, a twin-screw extrusion granulation way or a banburying way through a banburying machine can be adopted and blending is performed at blending temperature which is generally used for nylon material. According to the technical scheme disclosed by the invention, the iron oxide is added as the deodorant on the premise of not losing the flame retardance of the red phosphorus flame retardant against the nylon material and mechanical properties thereof, the release of phosphine into environmental space can be prevented in the thermoforming process of the red phosphorus flame retardant nylon material, the resulted irritating peculiar odor can be eliminated and the healthy and environment-friendly requirements can be further met.
Description
Technical field
The invention belongs to material processing field, more particularly, relate to one and can weaken and even eliminate red phosphorus flame-retardant nylon material (as nylon 6) etc. and produce the using method of the ferriferous oxide of pungency peculiar smell in the time of high temperature process.
Background technology
Nylon material, because having the premium propertiess such as good electrical property, mechanical property, thermotolerance, toughness, wear resistance, oil-proofness, self lubricity, chemical proofing, is widely used in every field.Its flame retardant properties of the nylon of non-modified is poor, and its vertical combustion can only reach UL94V-2 level, and oxygen index is 24 left and right, and produces drippage in combustion processes, belongs to inflammable material, in use initiation fire very easily.Especially in electronic product field, Yin Nilong and the fire that causes is countless, causes damage larger, therefore, nylon flame-retardant modified is become to current academia and industry member is common pays close attention to and the problem of tackling key problem.
At present, for different application requiring, can be used for the fire-retardant fire retardant kind of nylon material a lot, comprise various Halogens and halogen-free flame retardants.Halogen containing flame-retardant is generally because the hydrogen halide in when burning can bring staining of air in the finite space, its application is very limited, but also there are some bromide fire retardants to meet European ROHS standard, be can meet the requirement of environmental protection on definite meaning, the flame retardant properties of its fire-retardant nylon material can reach UL94VO level and V1, the requirement of V2 level.Along with socioeconomic development, the halogen-free flameproof of nylon material progressively obtains more concerns, and halogen-free flameproof has become the fire-retardant important development direction of nylon, and in nylon, the wider halogen-free flame retardants of application is especially taking red phosphorus and trimeric cyanamide salt as main.The flame retardant properties excellence of halogen-free reinforced nylon product, fire-retardant rank can reach UL94V0 level, and have lowly separate out, anti-drippage, high electrical property and excellent heat resistance, CTI value is high, good electric property, shock strength is high, environmentally friendly, the advantages such as environmental protection.Thereby halogen-free reinforced nylon is applied widely in fields such as daily-use electrical appliance, electric connector, electronic and electrical equipments.
Red phosphorus is a kind of fire retardant cheap and easy to get, there is very high flame retarding efficiency, and can improve the arc resistance of goods, but also there is the problem of two broad aspect in the use of red phosphorus combustion inhibitor in nylon: exist on the one hand store and color aspect limitation, i.e. the fire safety problem of the links such as storage transport and goods color are limited to self color of red phosphorus itself; Be to do with red phosphorus the nylon material that fire retardant produces in production process and use procedure, all can have very large peculiar smell on the other hand, cause the Air quality variation in the finite space, affect producers and user of service's physical and mental health.For storing and color problem, have made some progress by the coated processing of red phosphorus particle at present, as development has formed some whiteness red phosphorus products, but aspect removal peculiar smell, still exist a lot of problems to need to solve.
The generation of present stage people to peculiar smell in red phosphorus flame-retardant nylon (as nylon 6) process, is commonly considered as red phosphorus and in nylon system, has generated phosphuret-(t)ed hydrogen (having stink, poisonous) and be diffused into and cause in air.Aspect the peculiar smell of removal red phosphorus flame-retardant nylon system, at present people mainly by add spices cover stink add that porous mass carries out limited absorption or by sequestering action to eliminate peculiar smell, but these methods are not or be difficult to thoroughly effectively solve Peculiar Smell, actual effect is not good enough, especially under the severe rugged environment such as high temperature process and burning condition, can not meet application demand.Also there is part bibliographical information to attempt getting around the use of red phosphorus combustion inhibitor, as substituted red phosphorus by BACNs such as exploitation reactive flame retardants, and then the Peculiar Smell of solution flame-retardant system, but due to the reason such as price and flame retarding efficiency, the popularization degree of the method is not high.Formation based on phosphuret-(t)ed hydrogen with discharge each link and stop the generation of its formation reaction and then avoid the generation of phosphuret-(t)ed hydrogen or block it toward disseminating in space, thoroughly solve thus Peculiar Smell, should be the important channel that solves red phosphorus flame-retardant nylon material Peculiar Smell, but rarely have the pertinent literature report of this respect.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, do not losing under the prerequisite of flame retardant effect and the mechanical property etc. thereof of red phosphorus combustion inhibitor to nylon material, by adding a kind of ferriferous oxide, can be under red phosphorus flame-retardant nylon thermoforming processing (being 260 DEG C as processing temperature) condition, suppress the release of phosphuret-(t)ed hydrogen to environment space, eliminate the pungency peculiar smell being caused by it, meet the Air quality requirement of producing upper health environment-friendly, also can suppress simultaneously red phosphorus flame-retardant nylon product in use possible phosphuret-(t)ed hydrogen discharge.
Technical purpose of the present invention is achieved by following technical proposals:
Ferriferous oxide is in the application of eliminating in red phosphorus flame-retardant nylon moderate stimulation smell.
Described ferriferous oxide is the active iron oxide compound that Z 250 and ferric oxide mix, and is prepared according to following step:
Take iron nitrate and be dissolved in deionized water, be made into the aqueous solution of 0.2mol/L; Then splash into ammoniacal liquor, until pH value reaches more than 10, staticly settle rear filtration, after filter cake is dried; At 300-700 DEG C, calcine and within 4-6 hours, obtain active iron oxide compound, obtain the active iron oxide compound that Z 250 and ferric oxide mix.
Taking nylon as 100 mass parts, red phosphorus addition is 10 mass parts, and ferriferous oxide addition is 1-5 mass parts.
Described ferriferous oxide deodovization agent directly joins in red phosphorus flame-retardant nylon material by the mode of melt blending.
While nylon, red phosphorus combustion inhibitor, deodovization agent three being mixed by melt blending, can adopt the mode of double-screw extruding pelletizing or Banbury mixer banburying, carry out blend at the normally used blending temperature of nylon material.
