Description

Technical field [0001] The present invention relates to a low-odor polypropylene composite, and more specifically to the preparation of a low-odor polypropylene composite by adding a multi-component odor inhibitor system that can effectively suppress unpleasant odors in the polypropylene composite material. Acrylic composite. The invention also relates to a preparation method of the composite material. Background technique [0002] In recent years, due to the rapid development of engineering modification technology of polypropylene materials, its application in the automotive field has become more and more widespread. However, as an important part of engineered polypropylene materials in the automotive field, various automotive interior parts made of engineered polypropylene materials can meet the corresponding requirements in all aspects of performance. However, because these materials release certain unpleasant odors to varying degrees, they have been increasingly questi...
