The invention discloses a polypropylene material as well as a preparation method and application thereof, belongs to the technical field of high polymer material modification, and solves the problem that mechanical properties and high light transmittance of a polypropylene material in the prior art are difficult to consider at the same time. The polypropylene material comprises the following raw materials in parts by weight: 40-90 parts of polypropylene, 0.5-5 parts of maleic anhydride grafted polypropylene, 5-15 parts of modified magnesium sulfate whiskers, 0.2-1.0 part of a transparent nucleating agent, 5-15 parts of a toughening agent and 0.2-0.8 part of an antioxidant, the modified magnesium sulfate whisker is magnesium sulfate whisker modified by a dispersing agent, a surfactant and gamma-aminopropyltriethoxysilane. The polypropylene material has high light transmittance and mechanical properties at the same time.

    一种聚丙烯材料及其制备方法和应用,属于高分子材料改性技术领域,克服现有技术中聚丙烯材料的力学性能与高透光率难以兼顾的问题。本发明聚丙烯材料原料以重量份计包括:40~90份聚丙烯、0.5~5份马来酸酐接枝聚丙烯、5~15份改性硫酸镁晶须、0.2~1.0份透明成核剂、5~15份增韧剂、0.2~0.8份抗氧剂;所述改性硫酸镁晶须是经分散剂、表面活性剂和γ‑氨丙基三乙氧基硅烷改性的硫酸镁晶须。聚丙烯材料同时具有较高的透光率和力学性能。
