Abstract

The invention discloses a composite mineral fiber-filled polypropylene composite material and a preparation method thereof. The aspect ratio of the powdery inorganic mineral filler is fully improved by fibrillating the powdery inorganic mineral filler, and overcomes the problem of its interaction with the polypropylene composite material. Propylene matrix compatibility issues, while ensuring excellent mechanical properties and appearance, has a lower density (less than 0.97g / cm 3 ), more stable melt fluidity, and higher rigidity, thereby pushing polypropylene / inorganic mineral composite materials to higher-end application fields, and realizing the purpose of aesthetics, light weight, and environmental protection of automotive polymer materials.

Description

technical field [0001] The invention relates to a polypropylene composite material, in particular to a composite mineral fiber filled polypropylene composite material and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's automobile industry, the research on the properties of polypropylene (PP) modified composite materials as an automotive polymer material has also received extensive attention. At present, traditional polypropylene / inorganic mineral composites generally have problems such as large defects, low melt index, rough surface and low hardness, and poor mechanical properties, which can only be applied to low-end products. [0003] Inorganic non-metallic mineral fillers are widely used in the production of plastics industry because of their low price and excellent performance. Inorganic metal mineral fillers are filled with organic polymers after surface chemical modification, which can improve the...
