Abstract

The invention belongs to the technical field of high polymers and relates to a high-strength high-toughness low-odor polypropylene composition and a preparation method and usage thereof. The high-strength high-toughness low-odor polypropylene composition comprises the following components in parts by weight: 50 to 80 parts of polypropylene, 2 to 9 parts of compatilizer, 0 to 10 parts of thermoplastic elastomer, 0.1 to 0.5 part of antioxidant, 0.2 to 1 part of deodorant and 15 to 35 parts of glass fiber. The composition selects low-odor homopolymerized and copolymerized polypropylene matrix resins, selects a low-odor compatilizer and a reactive deodorant simultaneously, and is simple in production process flow, high in production efficiency, continuous in production process and stable in product quality. The composition maintains the advantages of the polypropylene matrix, and additionally has the capacity of enhancing the strength and the toughness are improved, and reducing the odor is reduced, so that the composition has the comprehensive performance of high strength, high toughness and low odor; and moreover, the requirement on the automotive trim comfort can be well met, and the composition has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of polymers, and relates to a high-strength, high-toughness and low-odor polypropylene composition, a preparation method and application thereof. Background technique [0002] In recent years, due to the requirements of automobile lightweight and energy saving and emission reduction, plastic materials are more and more used in automobile interior and exterior trims. Polypropylene (PP) is widely used in interior and exterior parts of automobiles due to its low price, easy recycling, small specific gravity, high surface hardness, high elasticity, heat resistance, chemical stability, and good insulation. Bars, anti-scratch strips, door panels, instrument panels, pillars, lamp housings, glove boxes, armrests, etc. However, as people's awareness of comfort and safety continues to increase, people's requirements for the odor, strength and toughness of automotive materials are becoming more and more stringent, req...
