Abstract

The invention discloses a low-odor, low-volatile organic compound (VOC) and high-performance polypropylene composite material for automotive interior decoration and a preparation method for the composite material. The composite material is prepared from the following raw materials: 50 to 90 percent of polypropylene, 0 to 40 percent of inorganic filler, 5 to 15 percent of toughening agent, 5 to 10 percent of compatilizer, 0.5 to 5 percent of odor absorption masterbatch, 0.1 to 1.0 percent of antioxidant and 1.0 to 2.5 percent of color masterbatch, wherein a low-odor resin raw material and an additive are preferred; and a multi-component effective odor removal system is involved, and the aluminosilicate odor absorption masterbatch, the low-odor maleic anhydride-grafted polypropylene compatilizer, and an ingredient, namely nanometer activated zeolite in the filler cooperate to remove the odor of materials and reduce the diffusion of organic substances. The composite material has the characteristics of good odor, high surface performance, excellent mechanical properties, low cost and the like.

Description

Technical field: [0001] The invention relates to a low-odor, low-VOC, high-performance polypropylene composite material for automotive interiors. The prepared material can be used for automotive interiors, such as instrument panels, door panels, decorative pillars, etc., and belongs to modified polypropylene technology field. Background technique: [0002] Modified polypropylene series materials are the most used in automobile body plastics, which are used for large interior parts such as instrument panels, door guards, and decorative panels. When the temperature inside the car reaches a certain temperature, the volatile organic compounds in the polypropylene material will be released, fogging and producing odor in the car, affecting the driver's sight and causing physical harm to the occupants in the car. These volatiles may come from the residual monomers of the plastic raw materials themselves during synthesis, or the small molecules produced by degradation during proces...
