Description
Technical field
The present invention relates to a kind of polypropene compositions and preparation method thereof, belong to technical field of polymer materials.
Background technique
Automobile noise has become the important sources of noise pollution, not only influences the comfort of vehicle driver and passenger, also influences
The health of pedestrian.Therefore the preferable material of sound insulation effect need to be developed to apply on automobile.Automotive light weight technology is auto industry
The important directions of development, it is desirable that use the material of lightweight.High molecular material has the characteristics that light and easy processing, on automobile
To being widely applied.But the usual sound insulation effect of high molecular material is poor, it is difficult to meet sound insulation value requirement.
In order to improve the sound insulation property of high molecular material, people have carried out many researchs.CN 102002190B passes through poly-
10%~60% iron powder is added in propylene to improve the sound insulation property of material.CN106566070A by addition haloflex and
Iron powder makes modified polypropylene material have preferable sound insulation property.The inorganic filler additive amount of this method is high, influences the power of material
Performance is learned, and is unfavorable for loss of weight.CN 104725718A and CN107118490A pass through chemical blowing method preparation foaming poly- third
Alkene is had a wide range of applications in terms of the loss of weight of auto parts and components and sound insulation using the sound insulation effect of abscess.Both methods needs
Special injection-moulding device and technique are wanted, and the mechanical property of foamed material is lower.Therefore, it is still necessary to develop a kind of to prepare letter for this field
List and light sound-insulation PP composite material adorn components for automobile interior exterior.
