Application of polypropylene as age inhibiting material caused by ultraviolet light

The present invention provides a polypropylene material and its application as UV-ray resisting and anti-ageing material. The described polypropylene material is made up by adding beta nucleating agent into the polypropylene material, and the addition of beta crystal type nucleating agent can make the polypropylene material produce beta crystal type conversion, as compared with alpha crystal type polypropylene material, after it is irradiated by UV ray, the retaining rate of mechanical performance of said material can be greatly raised, and the effect obtained by means of beta crystal type conversion can be identical to that obtained by adding UV-photostabilizer.
