Abstract

The invention discloses a high-performance polypropylene material and a preparation method thereof, wherein the high-performance polypropylene material is prepared from the following components in parts by weight: polypropylene, polyethylene, an inorganic filler, a toughening agent, an amino-terminated hyperbranched ethylenediamine triazine polymer and a processing aid through mixing, extrusion and granulation. According to the invention, the amino-terminated hyperbranched ethylenediamine triazine polymer is used as a modification auxiliary agent in blending modification of polypropylene, andbased on the special structure of the amino-terminated hyperbranched ethylenediamine triazine polymer, the rigidity and the toughness of the polypropylene material can be obviously improved.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a high-performance polypropylene material and a preparation method thereof. Background technique [0002] Due to its light weight, low price, and excellent rigidity and toughness, polypropylene is currently one of the top five engineering plastics in general use, and has a wide range of applications in chemical, construction, automobile, home appliances and other fields. However, the rigidity and toughness of modified polypropylene materials are limited, especially as a pair of contradictory properties, it is difficult to improve simultaneously. [0003] The present invention proposes to use HBP as a modification aid for the first time, because HBP is a new type of polymer with a three-dimensional spherical structure, a large number of active terminal functional groups, a cavity structure inside itself, and many branch points. Adding HBP in the blending modification ...
