| titleOfInvention | Polypropylene composition with low content of VOC (volatile organic compounds) and preparation method thereof |
| abstract | The invention belongs to the technical field of modifying and processing of polymers, and particularly relates to a polypropylene composition with a low content of VOC (volatile organic compounds) and a preparation method thereof. The polypropylene composition is prepared from the following raw materials in percentage by weight: 45-97.5% of polypropylene resin, 0-30% of an inorganic filler, 0-20% of a plasticizer, 0.2-0.6% of silver oxide, 0.4-1% of an antioxidant, 0.2-0.6% of a dihydrazide compound, 0.2-1% of a light stabilizer and 0.3-3% of an additive, wherein the total percentage by weight of the raw materials is 100%. The polypropylene composition provided by the invention has the characteristic of low content of VOC, benzene substances and aldehyde-ketone compounds and is suitable for manufacturing interior parts of automobiles. The preparation method of the polypropylene composition comprises the following steps: weighing the raw materials in percentage by weight, mixing in a high-speed mixer, feeding the mixture of the raw materials into a twin-screw machine, melting, extruding and granulating, wherein the vacuum degree of the twin-screw machine is controlled at -0.03 MPa to -0.05 MPa. The preparation process of the polypropylene composition is simple and is easy to implement. |
