Abstract

The invention discloses a low-odor recycled-PP composite material used for automobiles. The composite material is characterized by being prepared from the following raw materials in parts by weight: 100 parts of recycled polypropylene, 10-30 parts of talcum powder, 5-15 parts of a toughening agent, 10-25 parts of raw gypsum powder, 0.1-0.5 part of a primary antioxidant, 0.1-0.5 part of an auxiliary antioxidant, 0.1-0.5 part of a lubricant, 0.1-0.5 part of a light stabilizer, and 1-5 parts of reactive castor oil. According to the composite material disclosed by the invention, the recycled PP isused, so that the composite material meets the requirements for low odor of automotive PP composite materials, is green, environmentally friendly and in line with a current development trend of greenness and environmental protection, has lower costs, and can be widely used for preparation of automotive parts such as air conditioners and fans; and a preparation method of the composite material hassimple compounding and processing processes, the composite material is easy to process and prepare, and the method has high production efficiency.

Description

technical field [0001] The invention relates to the technical field of composite materials for automobiles, in particular to a low-odor PP recycled composite material and a manufacturing method thereof. Background technique [0002] Polypropylene (PP) has the advantages of low density, high hardness, and high heat distortion temperature, and is easy to process and low in price. It is widely used in the manufacture of auto parts and other fields. As the automotive industry has increasingly stringent requirements on material performance, environmentally friendly low-VOC (Volatile Organic Compounds) materials have become one of the hot spots and directions for the development of automotive parts. PP recycling, especially ton bag recycling, is relatively pure and has stable performance. Its recycling can effectively reduce the consumption of petroleum resources and realize green circular development. However, due to its repeated processing and long-term use, it produces VOC The...
