Abstract

The invention discloses a metallic spraying-free polypropylene composite material for an automobile exterior trimming part and a preparation method thereof. The material is prepared from the following components in percentage by weight: 37.2 to 74.6 percent of polypropylene, 5 to 10 percent of an elastomer, 10 to 30 percent of inorganic mineral master batch, 3 to 6 percent of a compatilizer, 0.4 to 0.8 percent of an anti-oxidant, 0.3 to 0.6 percent of a light stabilizer, 0.5 to 1 percent of a lubricant, 0.2 to 0.4 percent of a nucleating agent, 4 to 8 percent of a surface modifier, and 2 to 6 percent of metallic pigment master batch. The metallic spraying-free polypropylene composite material for the automobile exterior trimming part has the advantage that the defects, such as silver powder flow marks and tiger skin wrinkles, which are easily caused by a spraying-free material can be overcome; a metallic effect is very remarkable, is equivalent to that of paint, and can completely replace a painting effect; the material is easy to produce and process and obvious in cost advantage, and can completely solve environmental protection problems; large-scale industrial production can be realized; therefore, the material has a great industry prospect.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and relates to a metal texture spray-free polypropylene composite material used for automobile exterior decoration parts and a preparation method thereof. Background technique [0002] Polypropylene material has the advantages of wide range of sources, low density, corrosion resistance, and good bending fatigue resistance. After modification, polypropylene material has better mechanical properties and heat resistance, and its comprehensive performance is also very outstanding. At present, among the plastic materials used in automobiles, modified polypropylene material is the most used material. [0003] With the rapid development of the automobile industry, plastics for automobiles not only play an important role in aesthetics, safety, and lightweight, but also contribute greatly to environmental protection. At present, most of the exterior parts of automobiles are painted. Before paint...
