Problems solved by technology

However, the current engineering plastics still have disadvantages such as low strength, no toughness, low gloss, poor thermal oxygen stability, high production cost, and complicated production methods.
[0003] While engineering plastics satisfy people's life and social development, the social and environmental problems caused by the "white pollution" caused by the sharp increase in plastic waste are also becoming more and more serious. The "white pollution" caused by waste engineering plastics has begun to cause headaches for people. Engineering plastics that rot and do not decompose cannot be effectively recycled

Description

technical field [0001] The invention belongs to the technical field of engineering plastics, and in particular relates to a novel engineering plastics and a preparation method thereof. Background technique [0002] Engineering plastics can meet higher requirements in terms of mechanical properties, durability, corrosion resistance, heat resistance, etc., and are more convenient to process and can replace metal materials. Engineering plastics are widely used in electronics, automobiles, construction, office equipment, machinery, aerospace and other industries. It has become an industrial trend to replace steel and wood with plastic. With the continuous development of science and technology, aerospace, electronic communication and other industrial sectors have higher and higher requirements for "light weight", "high temperature resistance" and "high performance" of engineering plastics. However, the current engineering plastics still have disadvantages such as low strength, n...
