Abstract

The invention discloses a high-blue-phase high-heat-resistance polypropylene composition as well as a preparation method and application thereof. The polypropylene composition comprises the following components in parts by weight: 40-90 parts of polypropylene resin, 0-30 parts of a toughening agent, 0-30 parts of a filler, 0.5-4 parts of POE (Polyolefin Elastomer)-based carbon black master batch and 0.2-0.6 part of an antioxidant, wherein the POE-based carbon black master batch is prepared from the following components in parts by weight: 40 to 70 parts of POE resin, 30 to 50 parts of carbon black, 0 to 10 parts of filler and 1 to 5 parts of dispersing aid. According to the invention, the carbon black is firstly dispersed in the POE resin to prepare the POE-based carbon black master batch, and then the polypropylene material is modified, so that the finally prepared polypropylene composition has high blue phase and high heat resistance, and can be well used for preparing automobile interior and exterior ornaments.

Description

technical field [0001] The invention relates to the field of polymer materials and their molding processing, in particular to a high-blue-phase high-heat-resistant polypropylene composition and its preparation method and application. Background technique [0002] As a cost-effective general-purpose plastic, polypropylene is widely used in home appliances and automobiles because it has excellent mechanical properties such as high strength and high toughness, chemical resistance and high heat resistance after modification. For automotive interior polypropylene materials, there are usually high blackness and high blue phase appearance requirements. The blue-phase polypropylene can enhance the visual effect of black; at the same time, because the car is often parked in the open air, the interior of the car is frequently in a high-temperature environment, so the market proposes that the car interior should not be heat-resistant for 400-700 hours at 150 °C. And other thermal oxyg...
