Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0022] Weigh the raw materials according to the formula amounts of each embodiment in the following table 1, add the weighed samples into the high mixer, rotate at a speed of 1000 rpm, and mix for 30 minutes. After fully mixing, the premix is ​​obtained, and then the premix is The mixed material is transferred to the twin-screw extruder. The extrusion temperature of the twin-screw extruder is: 180°C in the first zone, 190°C in the second zone, 180°C in the third zone, and 170°C in the fourth zone. Rotate at 600 r / min, extrude and granula...

Abstract

The invention discloses modified polypropylene for handles of ceilings of automobiles. The modified polypropylene which is a composite material comprises, by weight, 55-85 parts of polypropylene (PP), 3-10 parts of toughening agents POE (polyolefin elastomers), 1-5 parts of linear low-density polyethylene (LLDPE), 0.1-1 part of coupling agents, 0.2-0.5 part of hyper-dispersants, 0.1-0.5 part of beta-nucleating agents and 0.1-0.5 part of alpha-nucleating agents. The modified polypropylene has the advantages of high rigidity and toughness and wide application range.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a modified polypropylene for a car roof handle. Background technique [0002] With the development of the automobile industry, more and more stringent requirements are imposed on the parts of the automobile, such as the roof handle. At present, in addition to the conventional mechanical performance experiments, static load and airbag point explosion experiments are also added. The requirements for handle materials are getting higher and higher, not only requiring high rigidity, but also high toughness. However, the rigidity and toughness of PP materials cannot meet the ever-increasing quality requirements, nor can it meet the needs of both high rigidity and high toughness. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems existing in the prior art, and provide a modified polypropylene for a car roof handle. Th...
