Description
Technical field
The present invention relates to a kind of plastic material and preparation method thereof, relate in particular to a kind of automotive upholstery with anti-aging PP/HDPE plastics and preparation method thereof.
Background technology
Vestolen PP 7052, english abbreviation is PP, is nineteen fifty-seven at first to drop into industrial production in Italy, is another the important plastics variety after Vilaterm (PE).It has better heat-resisting property, also can not be destroyed at 135 ℃ of boiling 1000h, and the specific heat capacity of PP, thermal conductivity are all less than PE, but heat insulating ability is superior to PE.PP belongs to non-polar polymer, has excellent dielectricity and electrical insulating property, and electrical property does not receive the influence of ambient moisture and electric field frequency basically, and in the working range that allows, the temperature rising can make electrical property reduce, and its arc resistance is higher.The chemical resistant properties of PP is good, and except that strong oxidizer has the erosion action it, other reagent all do not have effect to it.PP at room temperature is insoluble to any solvent, but can be at some solvent, and like swelling in tetracol phenixin, trichloromethane, dithiocarbonic anhydride, the benzene, when temperature raise, PP was dissolvable in water in some solvent.PP is responsive to the effect of oxygen, particularly when temperature is higher.Its ultraviolet-resistant capacity is very poor, also is subject to the destruction of high-energy radiation, when receiving above-mentioned destruction, and its generation lower-molecular substance of all can degrading.The existence meeting of copper sharply strengthens the oxidative degradation speed of PP, makes its very fast embrittlement, so be referred to as " copper evil ".PP has outstanding stress cracking resistance.But its resistance to deterioration is not good.
Summary of the invention
To the above-mentioned deficiency that exists in the prior art, one of technical problem to be solved by this invention provides a kind of automotive upholstery with anti-aging PP/HDPE plastics.
Two of technical problem to be solved by this invention provides the preparation method of above-mentioned automotive upholstery with anti-aging PP/HDPE plastics.
The present invention seeks to realize through following technical scheme:
A kind of automotive upholstery comprises following components by part by weight with anti-aging PP/HDPE plastics: 100 parts of Vestolen PP 7052, high density polyethylene(HDPE) 20-30 part, terpolymer EP rubber 10-20 part, inhibitor 0.1-5 part.
Preferably, said automotive upholstery comprises following components by part by weight with anti-aging PP/HDPE plastics: 100 parts of Vestolen PP 7052, high density polyethylene(HDPE) 20-30 part, terpolymer EP rubber 10-20 part, inhibitor 0.5-2 part.
Further,
Said Vestolen PP 7052 is a COPP.
Said inhibitor is two dodecyl ester, three (2, the 4-di-tert-butyl-phenyl) phosphorous acid esters of thio-2 acid, butylated hydroxytoluene and N, a kind of or its mixture in the two hydrazines of N-diacetyl sulfo-two propionyl groups.
Preferably; Said inhibitor; Form by weight by following component: two dodecyl ester 10-20 part, three (2, the 4-di-tert-butyl-phenyl) the phosphorous acid ester 10-30 parts of thio-2 acid, butylated hydroxytoluene 10-20 part, N, the two hydrazine 5-10 parts of N-diacetyl sulfo-two propionyl groups.
Automotive upholstery according to the invention also comprises photostabilizer 0.2-1 part with anti-aging PP/HDPE plastics.
Wherein, said photostabilizer be Whitfield's ointment to octyl phenyl ester or right, right-isopropylidene bis-phenol salicylate.
The present invention also provides the preparation method of above-mentioned automotive upholstery with anti-aging PP/HDPE plastics:
Take by weighing each raw material by proportioning, after mixing, melting mixing, extruding pelletization promptly obtain said automotive upholstery with anti-aging PP/HDPE plastics.
Obviously, for improving other performances of product, can also add other auxiliary agents adaptively, in the present invention like fire retardant, tinting material and static inhibitor etc.
Concrete, in the present invention:
Said high density polyethylene(HDPE), High Density Polyethylene abbreviates HDPE as, is that a kind of percent crystallinity is high, nonpolar thermoplastic resin.The milky appearance of ortho states HDPE is to a certain degree translucent in meagre cross section.
Terpolymer EP rubber, english abbreviation is EPDM, is the terpolymer of ethene, propylene and non-conjugated diene hydrocarbon, 1963 begin to commercially produce.The topmost characteristic of EPDM is exactly its superior antioxidant, anti-ozone and erosion-resistant ability.Because terpolymer EP rubber belongs to polyolefine family, it has fabulous vulcanization characteristics.In the middle of all rubber, EPDM has minimum proportion.It can absorb a large amount of fillers and oil and influencing characteristic is little.Therefore rubber compound that can low preparation cost.
The 3-TSL 8330, English name: 3-Aminopropyltrimethoxysilane, CAS:13822-56-5.
The two dodecyl esters of thio-2 acid are claimed anti-oxidant DLTP again, English name: Thiodipropionicacid dilauryl ester, CAS number: 123-28-4.
Three (2, the 4-di-tert-butyl-phenyl) phosphorous acid ester, and English name: Tris (2,4-di-t-butylphenyl) phosphite, Chinese another name: oxidation inhibitor 168, CAS number: 31570-04-4.
Butylated hydroxytoluene, English name: Butylated hydroxytoluene, be abbreviated as BHT, the Chinese another name is DBPC 2,6 ditertiary butyl p cresol; 3,5-di-t-butyl-4-hydroxytoluene, CAS number: 128-37-0.
N, the two hydrazines of N-diacetyl sulfo-two propionyl groups, the two hydrazines of Chinese another name sulfo-two propionyl group diacetyls are copper(greening)inhibitor, and are non-volatile, pollution-free.
The contriver finds unexpectedly; With two dodecyl ester, three (2, the 4-di-tert-butyl-phenyl) phosphorous acid esters of thio-2 acid, butylated hydroxytoluene and N, the two hydrazines of N-diacetyl sulfo-two propionyl groups carry out composite use; Its antiageing effect is excellent more; Also have effects such as anti-copper except anti-oxidant, inhibitor and Whitfield's ointment be to octyl phenyl ester or right in addition, right-photostabilizers such as isopropylidene bis-phenol salicylate carry out composite; Also obviously strengthened its antiageing effect, its mechanism is still waiting the further research and inquirement of contriver.
Vestolen PP 7052 and high density polyethylene(HDPE), terpolymer EP rubber blend can improve its toughness and winter hardiness; Have anti-preferably ozone, anti-oxidant and corrosion resistance; Also has certain shockproof effect simultaneously; Add inhibitor and can promote the ageing resistance of product, through to two dodecyl ester, three (2, the 4-di-tert-butyl-phenyl) phosphorous acid esters of inhibitor thio-2 acid, butylated hydroxytoluene and N; The optimum ratio of the two hydrazines of N-diacetyl sulfo-two propionyl groups makes product have good ageing resistance, draws high intensity, flexural strength, modulus in flexure and shock strength simultaneously and all meets the demands.
Automotive upholstery of the present invention is with anti-aging PP/HDPE plastics; Have rubber bodies outward appearance and performance; Can be processed into the automotive upholstery of different shape with Shooting Technique easily, like glove box inner cover plate, gloves hopper, auxiliary fasia console body, parcel tray liner, panel parcel tray.
