Abstract

The invention provides a modified PP (polypropylene) regenerated material for automobiles and a preparation method of the modified PP regenerated material for the automobiles. The modified PP regenerated material is prepared from a PP homopolymerized drawing-grade crushed material, a PP homopolymerized injection-molding-grade crushed material, a PP copolymerized washing machine drum crushed material, a PP copolymerized high-impact sheet-grade crushed material and color masterbatch. By adoption of the preparation method, the modified PP regenerated material for the automobiles is stable in performance and superior to other single PP materials in physical properties such as impact strength and melt index. The modified PP regenerated material not only can be used for manufacturing of moderate-impact-resistant parts such as automobile door panels but also can be used for manufacturing of high-impact-resistant parts such as bumpers through further modification. In adoption of the material and method for automobile modification, simplicity in operation and low cost are realized.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a modified PP recycled material for automobiles and a preparation method thereof. Background technique [0002] Polypropylene (PP) has become the third general-purpose material in the world after polyethylene and polyvinyl chloride due to its low density, good heat resistance, balanced mechanical properties, and low price. It is widely used in electronics, machinery, Daily necessities and other industries. Polypropylene is not only closely related to people's daily life, but also has become an indispensable important material in industrial and agricultural production. In 2011, the total global consumption of polypropylene was 42.3 million tons, with an average annual compound growth rate of 4.5%. By 2020, the total global consumption of polypropylene is predicted to reach 62.4 million tons. However, with the increasing production and consumption of polypropylene, more...
