In addition, the odor of the polypropylene composite material is as low as 3.0, which reflects the low concentration of volatile gases in the polypropylene material.
In contrast, when the extractant is omitted, the odor rating of the polypropylene composite increases; the impact resistance of the polypropylene composite material without the nucleating agent is reduced; when POE is replaced with an elastomer having a higher MI, the flexural and impact properties of the material decrease.
The test result reflects that the nucleating agent, the extractant and the POE are mutually synergistic, so that the rigidity and the toughness of the material are improved, the material has high heat distortion temperature, and the material achieves good heat resistance, so that the service life of the material can be prolonged. Particularly, the addition of the beta nucleating agent induces a considerable part of alpha crystals of the polypropylene resin to be converted into beta crystals, so that the crystallinity of the material is increased, the heat resistance of the material is further improved, and the material has better toughness.
Meanwhile, the addition of the silicone master batch can obviously reduce the surface friction coefficient of the material, reduce the effect of external force on the material and obviously improve the scratch resistance of the material. The extractant is subjected to mutual dissolution extraction of a large amount of microbubbles formed by the extractant under the action of heat and shearing force and Volatile Organic Compounds (VOC) in the material, such as alkane, alkene, aldehyde, ketone and the like, and is pumped out in the vacuum negative pressure of a rear-end double-vacuum device, so that the devolatilization efficiency is improved, the effect of improving the smell of the material is achieved, and the high standard use requirement of a customer on a seamless airbag instrument board is met.
The polypropylene composite material disclosed by the invention can be used for preparing instrument boards, in particular to seamless airbag instrument boards by comprehensively considering the performances of impact resistance, low odor, heat resistance and the like of the polypropylene composite material.
The above examples are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above examples, and any other changes, modifications, substitutions, combinations, and simplifications that do not depart from the spirit and principle of the present invention should be made in the equivalent manner, and the embodiments are included in the protection scope of the present invention.
