Background technology
Polypropylene is with its steady price, luminance brightness and physical strength and be widely used in various fields.But polypropylene lacks shock-resistance and hardness, and in order to improve these defectives, has proposed by adding ethylene-propylene polymer rubber (EPM) and coming the production polypropylene resin composite as the talcum of mineral filler.
Compression moulding iron plate material has been used for conventional car wheel covering.But in recent years, be extensive use of stable on heating nylon or polyphenylene oxide with low specified weight and excellence.
At present, polyolefinic enhancing resin combination is used to reduce cost, and proposes many schemes and improve physicals.
For example, Japan postpones the flat 5-20561 of publication publication and discloses and comprise acrylic resin and with the wheel cover tire of organic silane compound surface-treated glass fibre.Acrylic resin comprises the polypropylene of talcum or moisture toxilic acid modification.
In addition, Japan postpones the flat 6-80839 of publication publication and discloses the wheel cover tire of making by injection blow molding comprises polypropylene, introducing has carboxyl it on polypropylene, with the fiber reinforced polypropylene resin composition of the glass fibre of silane treatment and polyethylene wax.
In addition, Japan postpones the flat 10-44701 of publication publication and discloses glass fiber-reinforced resin composition as the resin that is used to take turns cover tire, the crystalline blocks multipolymer that wherein comprises 40-90 weight part propylene-ethylene, the copolymer rubber of ethylene-propylene, acrylic resin with unsaturated carboxylic acid or olefinically unsaturated carboxylic acid derivatives modification, mean sizes is no more than 10 microns talcum, and glass fibre.
But the problem that more than is used to take turns the prior art polypropylene resin composite of cover tire is that the patience of its stiffness, impact and heat and hardness is deficiency because its insufficient crystalling propylene degree becomes.In addition, the glass fibre that is used to strengthen hardness causes and is reclaiming and reducing problem aspect the weight, and causes the problem of the bad and distortion of appearance.
Summary of the invention
The purpose of this invention is to provide a kind of polyolefine resin composition and use its car wheel covering, described polyolefine resin composition has excellent stiffness, shock-resistance, outward appearance, recyclability and luminance brightness and good thermotolerance.
Resin combination of the present invention comprises the superelevation crystalline polyolefin resin of optimizing content, polyolefin elastomer, the acrylic resin of modification and talcum, and the car wheel covering of being made by this resin combination injection blow molding does not have molding defect such as distortion, mold shrinkage, welding line and recovery have excellent stiffness, impact and hot patience and hardness simultaneously.
More specifically, polyolefine resin composition of the present invention comprises 50-79 weight % superelevation crystalline polyolefin resin, 10-20 weight % polyolefin elastomer, the average particulate diameter of the polypropylene of the modification that is grafted with unsaturated carboxylic acid or its acid anhydrides of 1-10 weight % and 10-30 weight % is no more than 5 microns talcum.
Being used for superelevation crystalline polyolefin resin of the present invention can be, for example, isotactic polyprophlene, polypropylene and a small amount of other polyolefinic multipolymer such as propylene-ethylene copolymers, the multipolymer of propylene and 1-butylene, the multipolymer of the multipolymer of propylene and 1-hexene or propylene and 4-methyl-1-pentene, or random copolymers or its mixture.Preferred content with the superelevation crystalline polyolefin resin that surpasses 96% isotaxy, five unit group fractions (pentad fraction) is 50-79 weight %.The content that is lower than 50 weight % is in luminance brightness, and stiffness and cost effectiveness aspect are not preferred.If content surpasses 79 weight %, going wrong aspect shock-resistance and the outward appearance.
The melt flow of superelevation crystalline polyolefin resin is preferably 20-80g/10min (ASTM D1238,230 ℃), or more preferably 30-60g/10min.Be used for superelevation crystalline polyolefin resin of the present invention and be limited to the resin that surpasses 96% isotaxy five unit group fractions having with part (homo moiety), its effect is to improve the flowability of olefin elastomer and increase thermotolerance and hardness.If be lower than 96% with the isotaxy five unit group fractions in the part, then the stiffness of superelevation crystalline polyolefin resin, shock-resistance, thermotolerance and hardness descend and also have the thermotolerance and the hardness of reduction by this resin moulded wheel cover tire.
The thermoplastic polyolefin elastomer resin that is used for resin combination of the present invention can be an ethylene/propylene copolymer rubbers, ethylene/propene/Dicyclopentadiene (DCPD) rubber, ethylene/propene/1,4-hexadiene rubber, ethylene/propylene/dicyclopentadiene rubber, ethylene/propene/methylene radical novodene rubber or ethylene/propylene/ethylidene novodene rubber, and the content of comonomer is 10-40 weight % or preferred 20-30 weight %, with the Mooney viscosity (ML1+4,100 ℃) of thermoplastic polyolefin elastomer be 10-100 or more preferably 20-70.Except above resin, hydrogenated styrene-butadiene block copolymer (SEBS), hydrogenated styrene-divinyl rubber (HSBR), styrene ethylene-butylene block-copolymer (SEBC) or crystalline ethylene-butylene block-copolymer (CEBC) can be used as the thermoplastic polyolefin elastomer resin.
Thermoplastic elastomer is given the elastic performance of resin and is demonstrated flexibility and snappiness.If use Mooney viscosity (ML1+4,100 ℃) to be lower than 10 elastomerics, then increase mobile in deterioration in physical properties.If use Mooney viscosity (ML1+4,100 ℃) to surpass 100 elastomerics, then physicals is improved, but mobile decline caused the molding difficulty.
Thermoplastic elastomer resin is mixed with the superelevation crystalline polyolefin resin, improve shock strength like this and increase dispersiveness and coating performance.The content of thermoplastic elastomer resin is 10-20 weight %.If this content is lower than 10 weight %, then do not have significant shock strength to increase, and if this content surpasses 20 weight %, the problem that stiffness and shock-resistance die down then appears.
The polypropylene that is used for the modification of resin combination of the present invention is used to improve the coating performance of wheel cover tire and improves shock-resistance and thermotolerance by the steatitic interfacial adhesion that increases composition.
By with crystalline polypropylene, unsaturated carboxylic acid or its acid anhydrides are introduced biaxial extruder and by making temperature 180-220 ℃ of following heat fused to the acrylic resin of modification by the melt-mixing method.
The polyacrylic content of the modification of making by grafting unsaturated carboxylic acid or its acid anhydrides is preferably 1-10 weight %.If this content is lower than 1 weight %, the effect that then improves coating performance reduces, and if this content surpasses 10 weight %, the effect that then increases the steatitic interfacial adhesion descends, this is the hardness main reasons for decrease.
The average particulate diameter that the talcum that is used for resin combination of the present invention is measured by the laser diffraction and scattering method is no more than 5 microns or preferred 1-4 micron.If particle diameter is greater than 5 microns, then specific surface area can not be sufficiently big and hardness and shock-resistance said composition reduce.
In addition, in order to improve physical strength, thermotolerance and weather resisteant, the preferred use carried out the surface-treated talcum with silicon.
The reason that realizes this effect is also unclear, but can think that the dispersiveness of talcum on polypropylene resin composite and polyolefin elastomer becomes better by handling the steatitic surface with the silicon of silane compound modification, and the binding property of various additive on talcum descends greatly.
Can add various additives such as toughener, filler, heat-resisting stabilizing agent, weather-proof stablizer, the protective material that electrifies, lubricant; the slip additive, nucleator, flame-retardant additive, wollastonite, lime carbonate; mica, kaolin, clay, as long as barium sulfate or calcium sulfate are this being added in the object of the invention scope.
