Polypropylene product as well as preparation method and application thereof

The invention relates to the field of polymer materials, and discloses a polypropylene product as well as a preparation method and application thereof. Wherein the polypropylene article comprises an oriented homo-polypropylene, a beta nucleating agent, and optionally an antioxidant; relative to 100 parts by weight of oriented homo-polypropylene, the content of the beta nucleating agent is 0.05-0.5 part by weight, and the content of the antioxidant is 0-3 parts by weight; the bending strength of the polypropylene product is greater than or equal to 100 MPa, and the bending modulus is greater than or equal to 6 GPa. The polypropylene product provided by the invention is high in crystal content and crystal orientation degree, so that the polypropylene product has relatively high Rockwell hardness, bending strength and bending modulus. 本发明涉及聚合物材料领域，公开了一种聚丙烯制品及其制备方法和应用。其中，所述聚丙烯制品包含取向的均聚聚丙烯、β成核剂和可选地抗氧剂；相对于100重量份的取向的均聚聚丙烯，所述β成核剂的含量为0.05-0.5重量份，所述抗氧剂的含量为0-3重量份；所述聚丙烯制品的弯曲强度大于等于100MPa，弯曲模量大于等于6GPa。本发明提供的聚丙烯制品中的晶体含量和晶体的
