Description
Technical field
The invention belongs to the material modification technical field, be specifically related to a kind of polyvinyl chloride composite materials.
Background technology
Modified polyvinyl chloride material satisfy that automobile is attractive in appearance, comfortable, safe, anticorrosion, lightweight and design freedom are big etc., and the aspect plays the irreplaceable effect of other material.In numerous filling grade PVC materials; The reinforced PVC matrix material has advantages such as high rigidity, thermotolerance, chemical resistance, weather-proof and dimensional stability; Instead of copper, steel, nylon etc. are widely used in fields such as automobile, electrical equipment, motor, household electrical appliances within the specific limits.When glass reinforced polyvinyl chloride matrix material uses as automotive upholstery and part household electrical appliances product,, good low odor properties to be arranged also except requiring to have good mechanical performance, processing characteristics, the weather resistance.
In order to limit inside gadget material smell; Each big automaker also sets about having carried out the research work of this respect in the world, and has formed respectively to these volatile injurant matter standard of standard and control in addition, like the VW ' s PV3900 of Volkswagen standard; It adopts 1 ~ 6 grade of evaluation; Rank is high more, and smell is big more, just can meet the demands smaller or equal to 3 grades.This patent promptly adopts PV3900 that smell is graded.
Mineral-filled polyvinyl chloride composite materials such as reinforced PVC matrix material and conventional talc powder are compared, and its smell source is more extensive.At first, for improving the consistency of spun glass and resin, commercially available fiberglass surfacing generally all can be through coupling agent or respective acids anhydride modification, and the spun glass of handling through modification has certain acidic smell, and commercially available talcum powder does not then have smell; Simultaneously, in order further to guarantee the consistency of spun glass and PVC RESINS matrix, improve mechanical property; In glass reinforced polyvinyl chloride mixture, add compatilizer through regular meeting, like the maleic anhydride graft SE; Must contain unreacted maleic anhydride small molecules in this type of compatilizer, and content of glass fiber is different, the ratio of the compatilizer of interpolation is also inconsistent; It is also different to contain the micromolecular amount of maleic anhydride, and the smell influence that is brought is also different; Secondly, glass reinforced polyvinyl chloride matrix material is in the course of processing, because spun glass has higher length-to-diameter ratio; Friction between itself and the screw rod is more violent than talcum powder; The shear heat of being brought makes that glass reinforced polyvinyl chloride system temperature is higher, considerably beyond talcum powder filling polyvinyl chloride system, makes that the decomposition of PVC RESINS is more violent; The thermooxidative degradation product of PVC RESINS under comparatively high temps comprises CO, H
2Other aldehydes and ketone such as O, formaldehyde, acetaldehyde, acetone, these group compounds of aldehydes and ketones have comparatively strong impulse property smell.Once more; PVC RESINS is because the existence of initiator and catalyst system; And in the course of processing in order to reduce the decomposition of PVC RESINS, some functional agent is like the adding of oxidation inhibitor, weather resisting agent etc.; Also can introduce certain smell, this part smell source is similar with traditional talcum powder infill system source.Above many-sided acting in conjunction makes the reinforced PVC matrix material compare with the talcum powder system; The source that more has smell property VOC molecule is arranged; Has strong impulse property smell more; Oder levels often reaches 6 grades, influences its use as automotive upholstery and part household electrical appliances product.
Reduce smell in the prior art and generally take two kinds of measures: 1. substitute those unpleasant additives with low smell substitute; 2. add deodorant agent or absorption agent, comprise chemical reaction and physical adsorption method.
Chemical reaction method be meant some can with the additive of scent of small-molecule substance reaction; These additives and small molecules reaction; Produce the another kind of compound that molecular chain is big, in general environment, can not evaporate; Thereby reach the purpose that suppresses smell, for example zinc ricinate suppresses smell through chelating aldehyde, ketone molecule.Suppress for physics, theoretically, a large amount of poroid empty structures can have restraining effect to the small molecules that produces smell or other fugitive constituents, therefore possibly the inhibition effect all arranged to the output all respects that produce smell.And along with the physical adsorption industrial expansion, absorption or inhibition kind are more and more.Comprise gac, silica gel, Attapulgite, clay mineral system, molecular sieve, zeolite, wollastonite, wilkinite etc., when they are dispersed in resin system, can suppress the aperture and from material, volatilize, thereby reduce smell less than the small-molecule substance of self micropore.
Around above-mentioned factor, people do a lot, and most of work concentrates on the smell problem that additive brought in mineral powder fillings such as solving smell that SE itself has and talcum powder and the modifying process.Patent USP.5 mentions in 106,056 adopting in the high temperature extruding pelletization process and vacuumizes, and solves the smell negative impact that catalystsystem brought in the polyvinyl chloride polymerization process to the granulation material of producing in the method for drying under the high temperature; Patent USP5 proposes in 023,286 to solve the talcous smell problem of adding in the filling-modified SE with zinc oxide, titanium oxide.In the patent of retrieval; The patent that solves reinforced PVC matrix material smell problem is rarely found; And major part concentrates on through changing Shooting Technique or reach the purpose of low smell through the method for physical adsorption, proposes to obtain low smell spun glass and strengthen polymer composite through improving working method like patent KR20070014490; Patent 200810039827.8 proposes to obtain with the method for hydrophobic molecule sieve a kind of Reinforced Nylon matrix material of low smell, and effect is all not satisfactory.
