Description

Polypropylene modified composite material bumper
Technical field
The present invention relates to automobile component Material Field, particularly polypropylene modified composite material bumper.
Background technology
PP is a kind of semi-crystalline material.It is harder and have higher fusing point than PE.Because the PP temperature of homopolymer type is highly brittle lower than when less than 0 DEG C, therefore the PP material of much business adds the Random copolymer RCP of 1 ~ 4% ethene or the pincers segmentation multipolymer of more height ratio ethylene content.The PP material of copolymer type has lower hot torsion temperature (100 DEG C), low transparency, low-luster, low rigidity, but has stronger resistance to impact shock.The intensity of PP increases along with the increase of ethylene content.The vicat softening temperature of PP is 150 DEG C.Because degree of crystallinity is higher, surface rigidity and the anti-scratch characteristic of this material are fine.There is not environmental stress cracking problem in PP.Usually, adopt add glass fibre, the method for metal additive or thermoplastic rubber carries out modification to PP.The turnover rate MFR scope of PP is 1 ~ 40.The PP material impact property of low MFR is better but ductility/strength is lower.For the material of identical MFR, wanting of the strength ratio homopolymer type of copolymer type is high.Due to crystallization, the shrinking percentage of PP is quite high, is generally 1.8 ~ 2.5%.And the direction homogeneity of shrinking percentage is more far better than materials such as PE-HD.The glass additive adding 30% can make shrinking percentage drop to 0.7%.The PP material of homopolymer type and copolymer type all has excellent resistance to water soak, antiacid caustic corrosion, resist dissolution.But it does not have resistibility to aromatic hydrocarbon solvent, chlorinated hydrocarbon solvent etc.PP does not resemble PE yet at high temperature still has oxidation-resistance.About the PP resin ratio be used in injection-molded item can account for half, wherein daily necessities with common PP for raw material, auto parts machinery with strengthen or Toughened PP for raw material, other purposes is then based on the Co-polypropylene PPC raw material of high impact and low embrittlement temperature.PP more and more becomes the leading material of auto parts machinery, becomes first automotive plastic kind.Toughened PP is used for collision bumper and hubcap etc., strengthens PP then for panel board, bearing circle, handle, container, battery jar etc.Polypropylene is the polymkeric substance of the oyster white height crystallization of nontoxic, odorless, tasteless, and it is stable especially to water, and the water-intake rate in water is only 0.O1%, good moldability, and product surface good luster is easy to painted.Polyacrylic degree of crystallinity is high, compound with regular structure, thus has excellent mechanical property.The absolute value of Mechanical Properties of PP higher than polyethylene, but still belongs to kind on the low side in a plastic material, and its tensile strength only can reach 30MPa or slightly high level.The polypropylene that isotactic index is larger has higher tensile strength, but with the raising of isotactic index, the shock strength of material declines to some extent, but no longer changes after dropping to a certain numerical value.Temperature and loading rate very large to polyacrylic Toughness.When temperature is higher than second-order transition temperature, impact fracture is ductile rupture, be brittle rupture, and impact value significantly declines lower than second-order transition temperature.Improve loading rate, the temperature that ductile rupture can be made to change to brittle rupture rises.Polypropylene has excellent flexural fatigue resistance, its goods bent 106 times and do not damage at normal temperatures.Polypropylene has good thermotolerance, and goods temperature to carry out disinfection sterilizing more than 100 DEG C, and not by under the condition of external force, 150 DEG C also indeformable.Embrittlement temperature is-35 DEG C, embrittlement can occur lower than-35 DEG C, and polyacrylic chemical stability is fine, outside decapacitation is corroded by the vitriol oil, concentrated nitric acid, all more stable to other various chemical reagent; But low-molecular-weight aliphatic hydrocarbon, aromatic hydrocarbon and chlorinated hydrocarbon etc. can make polypropylene softening and swelling, its chemical stability also increases with the increase of degree of crystallinity simultaneously, so polypropylene is applicable to making various chemical pipeline and accessory, anticorrosion ability is good.Polypropylene is very sensitive to ultraviolet, adds zinc oxide, Tyox B, carbon black or similar milky white filler etc. and can improve its ageing-resistant performance.At present mostly there is the control of shrinking percentage for the material of collision bumper bad, PASS is low, and material weathering resistance is poor, poor toughness shock resistance is undesirable, and elongation at break is little of the problem such as heat-drawn wire is low.Chinese invention patent application CN1566196A discloses a kind of polypropylene composite materials, it is made up of the component of following weight part: Co-polypropylene pellet 25-60, thermoplastic elastomer 5-20, high density polyethylene(HDPE) 0-20, mineral filler 0-40, polar macromolecule material 0-10, thermal oxidation resistance agent 0.1-0.6, coupling agent 0.1-0.3, photostabilizer 0.1-0.3, it has extremely strong sticking power, but the volume change of material is comparatively large, and shock resistance is poor; And mobility time shaping is poor, complicated process of preparation.Chinese invention patent CN1235989A discloses a kind of modified poly propylene composition of paintable, said composition comprises 100 parts of polypropylene, 10 ~ 50 parts of rubber-type toughner, 5 ~ 15 parts of oligopolymer, 5 ~ 20 parts of graft modification polypropylenes, 1 ~ 15 part of inorganic filler, it is by above-mentioned various material Homogeneous phase mixing in proportion, under processing temperature 180 ~ 220 DEG C of conditions, extruding pelletization or Banbury mixer granulation after melt blending and obtain; Composition its shock strength obtained with aforesaid method is up to 629.6J/m, and when as when preparing the material of bumper, its impact strength is high not enough, can not absorb more impact energy, thus reduces the safety performance of automobile.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of polypropylene modified composite material bumper, bumper material good fluidity, is easy to processing, even and if effectively reduce shrinking percentage material and use in hot and humid environment and also can not deform and post shrinkage; Other mechanical performance indexs of polypropylene automotive material can be met simultaneously.
