Problems solved by technology

[0013] Patent US6376741 proposes substrates with odor control compositions including silica and zeolites, however, conventional odor control compositions are less effective in demonstrating overall odor control
[0014] Since the odor of modified PP is the result of the interaction of multi-component odors, the above-mentioned single method cannot completely solve this problem. It needs multiple ways and methods to work at the same time to hope to completely eliminate the odor and meet the development needs of automobiles and home appliances. ; and the above-mentioned patents did not consider the technical problem of the balance of rigidity and toughness of modified PP while solving the problem of odor

Abstract

The invention is a low-smell rigid-tough high-performance polypropylene composite material and a preparation method thereof. The composite material of the invention belongs to a polypropylene composition without chemical post-processing. The composite material of the invention comprises the following raw materials by weight: 60-85 parts of polypropylene, 14-15 parts of toughening agents, 5-30 parts of active mineral fillers, 0.5-3 parts of composite smell inhibitors, and 0.1-2 parts of routine additives. By using low-smell rigid-tough balanced basic resin, through filling of wollastonite whiskers and compounding, matching and optimization of various smell adsorbents, the prepared polypropylene composite material has less smell and good balance between rigidity and toughness. Wollastonite whiskers are added in a mode of lateral feeding, which avoids the damage of the wollastonite long-needle shape caused by screw strong shearing, and thus the prepared polypropylene composite material not only has increased rigidity, but also has basically non-influenced toughness. The preparation process is simple, and the production cost is low. The composite material is suitable for the manufacturing of automobile bumpers, instrument panels, engine fans, washing machine inner drums, and refrigerator drawers.

Description

technical field [0001] The invention relates to a low-odor rigid and tough high-performance polypropylene composite material and a preparation method thereof. Belongs to polypropylene compositions that have not been chemically post-treated. Background technique [0002] With the rapid development of household appliances and automobile industries, environmental protection, lightweight and functionalization have become the main trends in the development of these industries, and plastics and their composite materials have become their important structural and decorative materials. Polypropylene (PP) has been widely used in the automobile and home appliance industries due to its low density, high cost performance, excellent heat resistance, rigidity, corrosion resistance and easy processing. The fastest variety. [0003] However, due to the shortcomings of general PP, such as high shrinkage rate, poor product dimensional stability, easy warping deformation, poor low temperatur...
