Technical Field
The invention belongs to the field of high polymer materials, and particularly relates to an aromatic polypropylene composite material and a preparation method and application thereof.
Background
The polypropylene material has wide application in the interior and exterior trim products in the automobile field due to good comprehensive performance. However, in addition to good mechanical properties, processability, weatherability, etc., these polypropylene parts are also required to have good odor properties, low odor, and low VOC properties.
The reasons for odor generation in composite polypropylene upholstery materials are manifold. The polypropylene matrix is mainly modified, the polypropylene in a molten state can undergo autoxidative degradation to generate certain low molecular compounds, and the low molecular compounds are contained in the modified material and are emitted during the use of a formed part and the part. The addition of the antioxidant is the most effective method for reducing the degradation of the polypropylene, but the commercially available chemically synthesized antioxidant is mainly a hindered phenol, hindered amine compound antioxidant or thioester antioxidant, which has a large pungent smell due to the existence of the amine group and sulfur-containing substances, and introduces a new pungent smell in the process of preventing the degradation of the polypropylene. Air in the automobile is seriously polluted, and the health of drivers and passengers is influenced.
