Description
Technical field
The present invention relates to the polypropylene composite material of a kind of low smell, low-volatile, more specifically relate to by adding a kind of smell inhibitor that can effectively suppress bad smell in the polypropylene composite material, reduce fugitive constituent in the polypropylene composite material, thereby prepare the polypropylene composite material of a kind of low smell, low-volatile.The invention still further relates to the preparation method of this matrix material.
Background technology
In recent years, because the fast development of polypropylene material through engineering approaches modification technology, therefore, it in the application of automotive field more and more widely.Yet, as the important component part of through engineering approaches polypropylene material in automotive field, the various automotive trim products of making by the through engineering approaches polypropylene material, though all can meet corresponding requirements on its use properties in every respect, but, therefore be subjected to the human consumer and more and more queried because these materials contain some bad smell or to the deleterious fugitive constituent material of HUMAN HEALTH all can discharging in varying degrees.And along with people's environment protection health consciousness constantly strengthens, suffered challenge will be more and more serious on the one hand at this for polypropylene material.For this reason, in order further to expand the application of polypropylene material, must search out an effective way to prepare low smell even scentless low-volatile polypropylene material in association area.
Usually, it is believed that the irritating smell in the polypropylene material or other harmful fugitive constituent materials are owing to the following aspects causes.At first, the catalyst system that uses in acrylic resin matrix building-up process contains the compound that some have the pungency peculiar smell, as ester compound or alkane derivative.This compounds can not be removed after resin polymerization is finished fully, and they remain in the middle of the acrylic resin, thereby makes polypropylene material have the pungency peculiar smell.Secondly, carry out at the acrylic resin matrix in the middle of the process of modification processing, acrylic resin more or less can produce the low molecular compound of some degraded under the fused state, as ketone, aldehyde compound.These material parts rest in the middle of the material after the modification, progressively give out irritating smell or other harmful fugitive constituent materials in the use of product.Once more, some filler components that added in the modified polypropylene material, as talcum powder, they can have some irritating smell or other harmful fugitive constituent materials equally.At last, some stablizer that is added in the modified polypropylene material also has certain pungency peculiar smell.
Round the factor of above-mentioned several respects, people do a lot, and related basic skills is physical adsorption and chemical reaction two big classes nothing more than.
Chemical reaction method is meant and adds in the middle of material prescription and can discharge the small molecules of smell or the additive of other harmful fugitive constituent substance reactions with these, by the reaction between these additives and the small molecules produce molecular weight big, use under the thermal environment normal, as less than 100 ℃, the another kind of compound that can from material, not evaporate, thus reach the effect of eliminating peculiar smell.Though the related reaction of this method is extremely complicated,, therefore progressively caused people's interest in recent years owing to can control other performances that do not influence material on this theoretical method.
In U.S. Pat P.4 Rifi etc. have pointed out that have ester compound in the catalyst system in the middle of isotatic polypropylene resin polymerization process, as the residue of ethyl benzoate, this class residue itself is some compounds that have the pungency peculiar smell in 851,499.For removing contained these materials that have of acrylic resin matrix, the method that he proposes is: 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 compounds, by above-claimed cpd and acrylic resin are melt extruded, carry out transesterification reaction at the ester class residue that makes these compounds in the middle of the process of extruding and have a peculiar smell and form other macromolecular compounds and be fixed in the middle of the resin, thereby reach the removal smell, reduce the purpose of fugitive constituent material.
In U.S. Pat P.5 Fukui etc. have mentioned the another kind of media that exists in 109,056, alkane derivative in relevant catalyst system in the middle of the acrylic resin polymerization process.The residue of this compounds also can exert an influence to the smell of polypropylene material.The solution that he proposes is to adopt the method for high temperature extruding pelletization, and adopts the mode that vacuumizes in the middle of the process of extruding, and again the particle of making is carried out flint dry at last, with this these residues is carried out physics and removes.
In U.S. Pat P.5 Burch etc. have mentioned the fugitive constituent small molecules that the method for using a kind of rosin ester solves the polypropylene material peculiar smell with irritating that cracking goes out in the middle of modification is subjected to thermal process in 041,483.
Abe etc. are at U.S. Pat P5, have proposed to use the mixture of a kind of zinc oxide, titanium dioxide and water to solve talcous smell or other harmful fugitive constituent material problems of adding in the modified polypropylene material in 023,286.
Yui etc. are at U.S. Pat P4,080, adopt a kind of alkyl 3 in 359, the method for 5-two-Te-butyl-4-hydroxyl-carboxylation styracin and dialkyl group thiodipropionate acetate mixture solves the smell problem that some stablizers brought of being added in the middle of the modified polypropylene material.
Above-mentioned these methods are on some angle, to the smell that reduces polypropylene material, reduce fugitive constituent material in the material and all have in various degree solution.Yet as the polypropylene material that the automotive trim product uses, the factor of relevant the problems referred to above that it will be considered at modifying process is not only certain discrete factor wherein.At first, the fundamental starting point that solves this class modified polypropylene material smell and other fugitive constituent materials 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 class 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 smell and the fugitive constituent material problem of adding mineral constituent also must be taken into account; At last, it is common also very high that the thermo-oxidative ageing of this class polypropylene material requires, and therefore must add corresponding stabiliser system, and this must consider in the stabilizer component some the smell problem that may bring.Above-mentioned the whole bag of tricks all is to stress certain aspect is wherein improved, and therefore can not solve the problem that all respects produce smells or other harmful fugitive constituent materials.
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.Yet, traditional physical adsorption method can only be to adopt gac as sorbent material usually, by the micropore in the gac small molecules that discharges smell in the macromolecular material is played adsorption, thereby reduce smell or other harmful fugitive constituent materials of material.This method unavoidably can produce a lot of problems.At first, because gac is from the color as black, so can only use in black material.Secondly, the gac addition is very big to the mechanical property influence of material.Simultaneously, we find material added gac as sorbent material after, because the micropore size size distribution inequality in the gac, difference is very big, maximum aperture is greatly to the 1000 Izod right sides, therefore often other intermediate molecular weight additives that add are simultaneously adsorbed together, influenced other characteristics of material so again, as thermo-oxidative stability etc.Therefore, this method practical value is little.
For this reason, if can find a kind of energy active adsorption to produce the small molecules of smell or other fugitive constituents, the sorbing material that does not have simultaneously the above-mentioned defective of gac again, then can develop a kind of above-mentioned each side factor that can fully take into account, solve low smell or the scentless low-volatile polypropylene composite material of above-mentioned various smell problems comprehensively.

Can see that with the contrast of Comparative Examples 1,2 the Kiselgel A material is to the influence of material odor property from embodiment 1-4 and 5-9.The interpolation of Kiselgel A material makes the smell of PP material significantly reduce, and the content of organic compound volatile matter also has minimizing in various degree in the while material.The generation explanation Kiselgel A material of this phenomenon has the good adsorption effect to the volatile matter that produces smell.The uniform ultra-fine micropore that distributes in the Kiselgel A material can well be anchored at these volatile matters that produce smell in the middle of the micropore, so show good odor property of PP material and the low characteristic of organic volatile content firmly.
It is about 2% the most suitable to it can also be seen that from embodiment 1-4 the addition of Kiselgel A is controlled at.At this moment, material not only possesses good odor property and the low characteristic of organic volatile content, and the basic physical and mechanical property of material might as well simultaneously.
Can see from embodiment 5-9, the PP material added the Kiselgel A material as the smell remover after, if need carry out further toughness reinforcing processing, then then can by an amount of toughner poe of interpolation to the PP material.
By the contrast of embodiment 2 with Comparative Examples 3, though being described, traditional activated carbon of sorbent can reduce the odor property of PP material equally, its influence to the basic physical and mechanical property of material is very big, does not have practical value substantially.Simultaneously because the micropore size size in the middle of the gac differs very big, the maximum diameter of hole can reach 1000 dusts, therefore, in melt extruding in the process of PP material, the various auxiliary agents such as stablizer of the intermediate molecular weight that may most of be added also are adsorbed simultaneously, cause other physics-chem characteristics of material also to lose greatly.The contrast of the heatproof air aging performance of this heatproof air aging performance by table 3 Comparative Examples 3 and other each embodiment and Comparative Examples can be known and see.
