Description

technical field

[0001] The invention belongs to the field of organic polymer compounds, and relates to a polypropylene composite material and its preparation method and application. Background technique

[0002] The steering wheel of a car is an important part of a car. It not only acts as an operating handle, but also absorbs most of the impact energy when a collision occurs during the driving process of the car, thereby ensuring the safety of the driver. The U.S. automobile safety standard FM-VSS203 stipulates that when a car is running at a speed of 24km / h, when a 35kg chest model is used to impact the steering wheel, the maximum load generated should be less than 11kN. Therefore, it is required that the material for the production of the steering wheel should have high impact strength and rigidity, corrosion resistance to gasoline, diesel oil, and sweat, good hand feeling, uniform surface gloss, non-glare, good dyeability and color fastness. Since there is a metal skele...
