Description

technical field [0001] The invention belongs to the technical field of notebook computer shells, and in particular relates to engineering plastics used for notebook computer shells and a preparation method thereof. Background technique [0002] With the development of science and technology, people's lives are becoming more and more convenient. With the emergence of various consumer electronics products, industrial control equipment electronics products, and vehicle-mounted electronics products, people spend more and more time in contact with these electronics products. More and more attention has been paid to the safety and performance of use. Plastic materials are widely used in many parts of electronic products due to their light weight, corrosion resistance, easy processing, easy painting and coloring, and good insulation performance. At present, more and more products use plastic materials instead of metal materials as shell materials. However, in actual use, the plas...
