Description

A kind of modified polypropylene material and preparation method thereof
Technical field
The present invention relates to a kind of modified polypropylene material and preparation method thereof, relate in particular to a kind of modified polypropylene material that is applied to the low smell of automotive upholstery and preparation method thereof.
Background technology
In recent years; The smell problem of automotive upholstery has caused that world car is manufacturing and has shown great attention to; All contain a certain amount of volatile organic compounds in most of inner-decoration components; They mainly are the materials of alkane, alkene, aromatic hydrocarbons, acetaldehyde or ketone, and the boiling point of these materials is usually within 50~260 ℃ scope.When temperature reach a certain height, these volatile matter will discharge, and some can form the fog pass and condense on the front windshield, thereby influenced officer's sight line; Some then generation make us uncomfortable smell, even cause uncomfortable reaction such as headache, dry cough and allergy, thereby occupant's health damaged.Reducing the volatility of automotive upholstery material, improve the Air quality of automotive interior, is one of common target of pursuing of automaker and automotive material manufacturers.From the automotive plastic kind, Vestolen PP 7052 (being called for short PP) material accounts for more than 40% of automotive plastic, and wherein car interior trim consumption accounts for more than 2/3, so polypropylene material is one of main source of smell in the automobile.So, must take effective way to prepare low smell even scentless polypropylene material.
Usually, the smell of polypropylene material is owing to the following aspects causes.At first, the catalyst system that in acrylic resin matrix building-up process, uses contains the compound that some have the pungency peculiar smell, like ester compound or alkane derivative.This compounds can not be removed after resin polymerization is accomplished fully, and they remain in the middle of the acrylic resin, thereby make polypropylene material have irritating smell.Secondly, carry out in the process of modification processing at the acrylic resin matrix, acrylic resin more or less can produce the low molecular compound of some degraded under the fused state, like ketone, aldehyde compound.These material parts rest in the middle of the material after the modification, in the use of product, progressively give out irritating smell.Once more, some filler components that added in the modified polypropylene material, like talcum powder, they can have some irritating smell equally.At last, some stablizer that is added in the modified polypropylene material also has certain irritating smell.
The PP composite material and the complete processing that are used as the low odor dispersion level of automotive upholstery at present both at home and abroad mainly contain following 3 kinds of modes:
(1) devolatilization
This method mainly is to utilize the devolatilization equipment and technology of specialty in the Vestolen PP 7052 polymerization process, to carry out devolatilization.Fukui etc. adopt the method for high temperature extruding pelletization in U.S. Pat P 5109056; And in the middle of the process of extruding, adopt the mode that vacuumizes; At last the particle of making is being carried out flint dry, removing the residue of the alkane derivative that produces smell with this.Research shows, devolatilization in polymerization process, and efficient is higher, but because the limitation of its Processes and apparatus, and cost is higher, is difficult for widespread use.
(2) physisorphtion
This method mainly is to add sorbent materials such as mineral soil, zeolite molecular sieve such as gac, silica gel, attapulgite at Vestolen PP 7052, then through screw extrusion press extruding pelletization under certain process conditions.Can also plastics be placed among the odor adsorption agent such as gac and high surface area silicate, the vacuum-treat environment can be accelerated desorption process.The Chinese patent CN1730534A and the Shanghai Jinfa Technology Development Co., Ltd of Pulite Composite Material Co., Ltd., Shanghai's application all adopt zeolite molecular sieve material as physical absorbent in Chinese patent CN1840576A.Research shows, in polymkeric substance, fills a spot of zeolite molecular sieve material, can play the effect of removing the material smell.Zeolite has a large amount of crystallization cavities, and those gas molecules with smell can be caught in these cavities.The smell of gained material obviously reduces, and each item mechanical property of material is relatively good.
(3) chemical reaction method
This method is meant and in the middle of material prescription, adds the additive that can discharge the small molecules reaction of smell with these; Through the reaction between these additives and the small molecules produce molecular weight big, use under the thermal environment normal; As less than 100 ℃; Can from material, not evaporate the another kind of compound that produces peculiar smell, thereby reach the effect of eliminating peculiar smell.Yui etc. adopt alkyl 3 in U.S. Pat 4080359, the smell problem that some stablizers brought that the method for 5-two-Te-butyl-4-hydroxyl-carboxylation styracin and dialkyl group thiodipropionate acetate mixture solves in the modified polypropylene material to be added.Rifi etc. adopt a kind of esterification glyceride type compound, a kind of epoxy compounds, a kind of monohydroxy-alcohol or multicomponent alcoholics compound, a kind of fatty acid ester compound or the mixture of above-mentioned several kinds of compounds in U.S. Pat 4851499; Through above-claimed cpd and acrylic resin are melt extruded; In the middle of the process of extruding, make these compounds and the ester class residue that has peculiar smell carry out transesterification reaction; Form other macromolecular compounds and be fixed in the middle of the resin, thereby reach the purpose of removing this smell.Result of study shows that chemical reaction method can be controlled other performances that do not influence material in theory, but the related reaction of this method is extremely complicated, not easy to operate.
Above-mentioned research method about the automotive upholstery odor eliminating on some angle, all has solution in various degree to the smell problem of polypropylene material.Yet, as the polypropylene material that the automotive upholstery product uses, its in modifying process the relevant smell factor that will consider be not only certain discrete factor wherein.At first, the fundamental starting point that solves this type modified polypropylene material smell must consider that certainly acrylic resin matrix self some in the middle of polymerization process have the residue problem of pungency peculiar smell; Secondly, therefore this type modified polypropylene material all must will consider the thermo-cracking small molecules problem in the extruding pelletization process through melt extruding granulation; Once more, the thermo-oxidative ageing of this type polypropylene material requires also very high, therefore must add corresponding stabiliser system, and this must consider some the smell problem that possibly bring in the stabilizer component.And above-mentioned the whole bag of tricks all is that modification is carried out in certain aspect wherein, can not solve the problem that all respects produce smells.
Physical adsorption can be adsorbed the small molecules of any generation smell or other fugitive constituents in theory, therefore an ideal effect might all be arranged to all respects that produce this problem.And along with the physical absorbent industrial expansion, the multiple physical absorbent system that grown up at present comprises mineral soil body system, molecular sieve system etc. such as gac system, silica gel system, attapulgite.Based on adsorption effect, when above-mentioned serial sorbent systems was distributed in resin matrix with a definite form, they all can adsorb the small molecules that produces smell or other fugitive constituent in the resin material.Yet in the middle of the application of reality, they have deficiency separately again.For example, adopt traditional gac as sorbent material, before use by special sorbent material activating apparatus with its activation, the micropore through gac plays adsorption to the small molecules that discharges smell in the macromolecular material.The problem that this method produces is: the micropore size size distribution in the gac is uneven; Difference is very big; Maximum aperture reaches about 100nm; Therefore often the additive of other intermediate molecular weight of adding is simultaneously adsorbed together, this has greatly influenced mechanical property and the thermo-oxidative stability etc. of material.Therefore, gac using value in this regard is little.And when adopting mineral soil body system such as attapulgite to remove system as smell, it is uneven to be faced with sorbent material micropore size size distribution equally, and difference is very big, thereby causes problem that other intermediate molecular weight additives that add are adsorbed together.The general aperture of widely used now zeolite molecular sieve material<1.5 nm; Because its aperture is less, the major diameter molecule gets into the duct difficulty, and diffusional resistance is bigger simultaneously; The accumulative gas molecule can not be overflowed fast in its vestibule, thereby has limited its application in adsorbing domain.
