Description

[0001] 【Technical field】 [0002] The invention relates to the field of filler materials, in particular to a polypropylene filler masterbatch and a preparation method thereof. [0003] 【Background technique】 [0004] Polypropylene has excellent processing performance, and various processing methods can be used to produce different products for various purposes. However, polypropylene is brittle and has low fracture and tensile strength. Therefore, it is necessary to use modification methods to improve its inherent shortcomings and increase new features. In order to reduce costs with the greatest benefit, the use of inorganic powder filling modification has become the main way of polypropylene modification. [0005] The traditional inorganic powder filler modified polypropylene uses a single filler variety, such as talcum powder, calcium carbonate, etc., which can improve the mechanical properties of polypropylene to a certain extent. However, these fillers will greatly affect...
