Abstract

The invention discloses a method for modifying an in-reactor alloy polypropylene material for an automobile, which is characterized by comprising the following steps of: performing surface activation treatment on in-reactor alloy polypropylene at the temperature of between 100 and 300DEG C for 10 to 30 minutes by using 10 to 20 weight parts of nano filler; and adding 50 to 80 weight parts of in-reactor alloy polypropylene subjected to surface activation treatment, 5 to 10 weight parts of PP-7555KN, 0.5 to 5 weight parts of coupling agent, 0.5 to 1 part of photo-oxidant stabilizer, 0.5 to 1 weight part of antioxidant and 0.5 to 2 weight parts of polyethylene wax into a high speed stirrer for uniform mixing, performing melt extrusion by using an extruder, and extruding, granulating and drying by using a screw mixer to obtain the finished product. The method ensures raw materials are readily available, and is easy to operate, an elastomer is not needed to be added, the manufacturing costis reduced, the cost performance of the in-reactor alloy polypropylene material is improved, the single development of automobile materials is promoted, and automobiles are easy to recycle and remanufacture.

Description

Technical field [0001] The present invention belongs to the field of polypropylene plastic manufacturing in the internal and external decorations of the automobile, which involves a modified method for a alloy polypropylene plastic in the kettle in the internal and external decoration of the car. Background technique [0002] In car materials, the amount of polymer materials is rising.At present, with the increasingly prominent environmental protection issues and the continuous introduction of the corresponding environmental protection policies, the recycling of automotive materials has become a serious issue that the automotive industry must face.The life cycle of cars is generally 8-15 years. The increasing increase in car output and ownership in my country will inevitably bring impact on my country's automobile recycling industry and challenge the technology of abandoned car recycling.At present, the plastic consumed by each car is about 90kg to 130kg in the United States, acc...
