Description

technical field [0001] The invention relates to the field of automotive interior components, in particular to a high-strength and low-VOC automotive interior polypropylene composite material for automobile interiors and a preparation method thereof. Background technique [0002] With the continuous progress of industrialization and the continuous development of science and technology, people's requirements for travel are constantly increasing. Cars have become the preferred means of transportation for many people to commute and travel. And people's requirements for cars are not only fast speed and stable driving, but also the comfort and safety indicators of cars are also an important reference point for people to choose. [0003] As an important part of the car, the car interior is also a point that most car owners pay attention to when choosing a car. The car interior is usually made of plastic materials. Due to its characteristics, the volatilized VOC of plastic affects c...
