Description
Technical field
The invention belongs to material processing field, more particularly, relate to one and can weaken or even eliminate the using method that red phosphorus flame-retardant nylon material (such as nylon 6) etc. produces the iron oxides of zest abnormal flavour when high temperature process.
Background technology
Nylon material, because having the premium properties such as good electrical property, mechanical property, thermostability, toughness, wearability, oil resistivity, self lubricity, chemical proofing, is widely used in every field. Its fire resistance of the nylon of non-modified is poor, and its vertical combustion can only achieve UL94V-2 level, and oxygen index (OI) is about 24, and produces drippage in combustion, belongs to combustible material, in use very easily initiation fire. Particularly in electronics field, the fire caused because of nylon is countless, causes damage relatively big, therefore, nylon flame-retardant modified is become current academia and jointly pays close attention to and the problem tackled key problems with industrial quarters.
At present, for different application requirements, can be used for the fire-retardant fire retardant kind of nylon material a lot, including various Halogens and halogen-free flame retardants. Halogen containing flame-retardant is normally due to hydrogen halides during burning can bring staining of air in the confined space, its application is very limited, but also there are some bromide fire retardants to meet Europe ROHS standard, namely on definite meaning can meet the requirement of environmental protection, the fire resistance of its fire-retardant nylon material can reach UL94VO level and V1, V2 level requirement.Along with socioeconomic development, the halogen-free flameproof of nylon material progressively obtains more concern, and halogen-free flameproof has become the important development direction that nylon is fire-retardant, applies wider halogen-free flame retardants especially based on red phosphorus and tripolycyanamide salt in nylon. The excellent fireproof performance of halogen-free reinforced nylon product, the advantages such as fire-retardant rank is up to UL94V0 level, and has low precipitation, anti-drippage, high electrical property and excellent heat resistance, and CTI value is high, good electric property, and impact strength is high, environmentally friendly, environmental protection. Thus, 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 significantly high flame retarding efficiency, and the arc resistance of goods can be improved, but the problem that the use that red phosphorus combustion inhibitor is in nylon there is also two broad aspect: there is on the one hand the limitation stored and in color, namely the fire safety problem of the links such as storage transport and goods color are limited to the self color of red phosphorus itself; It is on the other hand do, with red phosphorus, the nylon material that fire retardant produces in production process and use procedure, all can have very big abnormal flavour, causes the air quality in the confined space to be deteriorated, affect the physical and mental health of producers and user of service. For storing and color problem, processed by the cladding of red phosphorus granule at present and have been achieved for some progress, as development defines some whiteness red phosphorus products, but in removing abnormal flavour, yet suffer from a lot of problem need to solve.
Present stage people are to the generation of abnormal flavour in red phosphorus flame-retardant nylon (such as nylon 6) process, it is considered that be that red phosphorus generates hydrogen phosphide (having stink, poisonous) being diffused in nylon system and causes in air. In removing the abnormal flavour of red phosphorus flame-retardant nylon system, current people cover stink mainly through interpolation spice or interpolation porous mass carries out limited absorption or by chelation to eliminate abnormal flavour, but these methods not or are difficult to thoroughly efficiently solve Peculiar Smell, actual effect is not good enough, especially under the harsh environmental conditions such as high temperature process and burning, it is impossible to meet application demand. Also part bibliographical information is had 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. Being formed and discharging each link and stop the generation of its reaction of formation and then avoid producing or blocking it toward disseminating in space of hydrogen phosphide based on hydrogen phosphide, thus thoroughly solve Peculiar Smell, should be the important channel solving red phosphorus flame-retardant nylon material Peculiar Smell, but rarely have the pertinent literature of this respect to report.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, do not losing red phosphorus combustion inhibitor under the premise of the flame retardant effect and mechanical property etc. thereof of nylon material, by adding a kind of iron oxides, can process in red phosphorus flame-retardant nylon thermoforming under (if processing temperature is 260 DEG C) condition, suppress the hydrogen phosphide release to environment space, eliminate the zest abnormal flavour caused by it, meet the air quality requirements producing upper health environment-friendly, also can suppress the hydrogen phosphide release that red phosphorus flame-retardant nylon product is in use possible simultaneously.
The technical purpose of the present invention is achieved by following technical proposals:
Iron oxides application in eliminating red phosphorus flame-retardant nylon moderate stimulation abnormal smells from the patient.
Described iron oxides is ferroso-ferric oxide and the active iron oxide of iron sesquioxide mixing, is prepared as steps described below:
Weigh ferric nitrate and be dissolved in deionized water, be made into the aqueous solution of 0.2mol/L;Then instill ammonia, until pH value reaches more than 10, filter after staticly settling, after filter cake is dried; At 300 700 DEG C, calcining obtains active iron oxide in 46 hours, namely obtains ferroso-ferric oxide and the active iron oxide of iron sesquioxide mixing.
With nylon for 100 mass parts, red phosphorus addition is 10 mass parts, and iron oxides addition is 15 mass parts.
Described iron oxides eliminating smell agent directly joins in red phosphorus flame-retardant nylon material by the mode of melt blending.
When making nylon, red phosphorus combustion inhibitor, eliminating smell agent three's mix homogeneously by melt blending, double-screw extruding pelletizing or the mode of banbury banburying can be adopted, carry out blended at the normally used blending temperature of nylon material.
