Problems solved by technology

[0007] In Patent No. CN103524872A, reactive castor oil is added to chelate ammonia, sulfur, and mercaptan odor molecules in the material through active groups in castor oil. Since this method can chemically chelate specific odor molecules, Therefore, it is impossible to remove the unreactable odor small molecule substances, and the odor of the material cannot be completely improved.

Abstract

The invention discloses an automobile interior polypropylene composition low in smell and density and a preparation method thereof. The automobile interior polypropylene composition is composed of, by mass, 70-85 parts of polypropylene, 5-15 parts of impact modifier polyolefin elastomer, 8-15 parts of talc powder, 0.1-0.5 part of antioxidant and 0.5-1.0 part of smell absorbing agent. The automobile interior polypropylene composition has the advantages of being low in smell, meeting the Changan smell standard 2.5 grade, and being low in density, capable of reducing product weight, excellent in mechanical property, good in rigid-tough balance and good in forming performance.

Description

technical field [0001] The invention relates to the technical field of modified materials, in particular to a low-odor, low-density automotive interior polypropylene composition and a preparation method thereof. Background technique [0002] Polypropylene (PP) material has been widely used in various assembly systems of automobiles due to its good comprehensive performance. Most of the automotive exterior and interior parts are injection molded using polypropylene composite materials. Exterior parts such as bumpers, door sills, skirts, etc., automotive interior parts such as instrument panels, pillars, glove boxes, door panels, etc. Since pure polypropylene is difficult to meet the performance requirements of various automotive parts, it needs to be modified by adding talcum powder, glass fiber, toughening agent, antioxidant and scratch resistance agent to meet its mechanical properties and long-term aging resistance performance. However, the addition of these substances ...
