Background
Polypropylene is one of the most widely used general plastics at present, has the advantages of excellent chemical corrosion resistance, good processing performance, low price and the like, and is widely applied to the fields of automobile industry, household appliances, building industry and the like. However, the general polypropylene material has the defect of poor low-temperature brittleness, and the low-temperature impact resistance of the polypropylene product is poor, so that the use of the polypropylene product in a low-temperature environment is limited, and therefore, the impact resistance of the polypropylene material, especially the impact resistance of the polypropylene material in the low-temperature environment, is urgently required to be improved.
In order to improve the impact properties of polypropylene, it is common to use elastomers to improve the low temperature brittleness of polypropylene materials, patent CN103665570a discloses an ultra low temperature resistant polypropylene composition consisting of polypropylene, an elastomer crosslinked with dicumyl oxide XPOE and a filler enhancer.

Patent CN104530574A discloses a polypropylene composition with stress cracking resistance and low-temperature impact resistance and a preparation method thereof, wherein the ultra-low temperature notch impact strength is 2-4 KJ/m 2. Patent CN106832575A discloses a polypropylene composition consisting of resin a, polyolefin elastomer, filler reinforcing agent, low temperature modifier, antimicrobial agent and auxiliary agent, which composition has good low temperature impact toughness. However, adding a large amount of toughening agent can obviously reduce the material strength of polypropylene and increase the material cost, and a polypropylene material with high enough low-temperature impact toughness and good rigidity combination is not obtained at present.
