Description

Polypropylene composite material that a kind of nerf bar is used and preparation method thereof
Technical field
The present invention relates to a kind of polypropylene composite material, specifically, relate to a kind of nerf bar polypropylene composite material and preparation method thereof.
Background technology
Polypropylene is used widely in inner and outer decorative parts of automobile because of its excellent cost performance, particularly is applied on the front and back collision bumper of automobile.From 1976, the blend composition making that Italy FIAT company adopts PP and E/P multipolymer is in the world since the first secondary collision bumper, polypropylene is used in automotive field extensively as a kind of inexpensive novel universal plastics, and the collision bumper more than 80% all is that employing is the TPO material making of matrix with the polypropylene in the world at present.The automobile insurance bar material is high to toughness reguirements, can absorb enough energy with the assurance automobile when being subjected to clashing into, thus passenger's safety in the service truck.Prior art generally adopts with the toughening modifying of polypropylene material nerf bar adds terpolymer EP rubber (EPDM) or ethene-1 octene copolymer (POE) reaches toughness reinforcing purpose, but above-mentioned two kinds of toughner cost an arm and a leg on the one hand, on the other hand owing to contain divinyl and the long carbochain comonomer of octene, long carbochain comonomer of this class and polypropylene matrix resin compatible are relatively poor, have influenced toughening effect.
Chinese invention patent application CN101544793A discloses a kind of polypropylene composite material that can be used for nerf bar, and it gets component by following weight part and forms: 71 parts of acrylic resins, 10 parts of talcum powder, 6 parts of looks female, 3 parts of tougheners, 4 parts of brightening agents, EPDM6 part.Little, the easy-formation of material proportion that makes by aforesaid method, but toughness is relatively poor, and EPDM costs an arm and a leg, and material cost is very high.
Chinese invention patent application CN101759923A discloses a kind of nerf bar polypropylene composite material and preparation method thereof, with the superfine talcum powder is filling, ethene-1 octene (POE) is a toughner, γ-An Jibingjisanyiyangjiguiwan (KH550) is a compatilizer, the material rigid-tough balance that makes is better, but the KH550 compatibilization effect is relatively poor, can not bring into play the toughening functions of POE fully, and the material price ratio is not high.
Chinese invention patent application CN101993563A discloses a kind of preparation method of nerf bar polypropylene material, the employing maleic anhydride grafts is a compatilizer, by nucleator NA-11 crystallization control size, the material flowability height that makes, Heat stability is good, but because system modulus height and toughness is low, the material rigid-tough balance is poor.
