Technical Field

Background
Polypropylene (PP) has low density, excellent mechanical properties, good stress cracking resistance, fatigue yield resistance, chemical resistance, low cost, easy processing and forming, easy recovery, and recycling, and has been widely used, especially in the automotive industry, home appliances, and machinery fields. However, polypropylene materials have poor low temperature resistance and low rigidity, and cannot meet the use requirements of automobile interior and exterior parts, so that the polypropylene materials need to be modified. The main modification method of polypropylene is elastomer toughening polypropylene modification; modifying the inorganic filler filled reinforced polypropylene; and the research on the modification of the toughening and strengthening polypropylene by utilizing the combined action of the polypropylene, the inorganic filler and the elastomer.
With the development of the automobile industry, people put higher demands on automobiles: light weight, energy conservation, beauty, safety, environmental protection and the like, and the requirement on the comfort in the cab is higher and higher. If the gloss of the trim in the cockpit is high, there will be a strong reflection of light, thus affecting the comfort of the driver. Therefore, the automotive upholstery is required to have low glossiness. The method of removing gloss by surface embossing has been put into practice but requires a separate step, increasing costs, and the subsequent abrasion also removes the embossed matte surface, thereby allowing gloss reproduction.
In addition, low gloss can be obtained by spraying a matte paint on the surface of the product, but the production cost is high, the use requirement cannot be met sometimes, and the product may need to be reprocessed along with the prolonging of the production time.
Researches show that the glossiness of the polypropylene composite material can be reduced by adding a finely-divided filler such as silica, silicate, aluminate or other inorganic fillers, however, the glossiness is not obviously reduced due to less adding amount of the inorganic fillers, and the use requirement cannot be met; too much addition will result in a decrease in the physical properties of the article, especially a more pronounced decrease in impact strength, with a corresponding heat change.
