Description
technical field [0001] The invention relates to the technical field of polymer materials, in particular to rigid and tough automotive interior materials. Background technique [0002] With the rapid development of the automobile industry, consumers not only pay attention to the beauty of the exterior shape of the car when buying a car, but more and more consumers have put forward higher requirements for the beauty, functionality and low emission of automotive interior materials. Automotive interior materials have become an important factor affecting the quality and grade of the vehicle. At present, the automotive interior materials include PVC artificial leather, PU artificial leather and so on. Materials used for automotive interiors should have good performance indicators, such as light resistance, low temperature resistance, flexibility, good flame retardancy, and low fogging. At the same time, they must meet the requirements of laws and regulations on the composition of...
