Gamma radiation resistant polypropylene composite material and preparation method thereof |
| abstract |
The invention relates to a polypropylene composite material and a preparation method thereof, wherein the polypropylene composite material comprises the following components in percentage by mass: 60-80% of polypropylene, 5-25% of butadiene rubber and 5-20% of low-density polyethylene. The polypropylene composite material is prepared by compounding polypropylene, butadiene rubber and low-density polyethylene, and the modified polypropylene composite material has high gamma radiation resistance (more than 30 KGy). |
