Problems solved by technology

[0002] Special engineering plastic composite materials 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. They are widely used in electronics, automobiles, construction, office In the equipment, machinery, aerospace and other industries, it has become an international trend to replace steel and wood with plastic, and it also promotes the transformation of traditional industries and the adjustment of product structure. However, the existing special engineering plastic composite materials crystallize after mixing The speed is slow, which makes the processing and molding process slow and the production process is not efficient. Secondly, the toughness of the material is poor, and the molding process is easy to break, resulting in poor processability. Therefore, we propose a special engineering plastic composite material and its Preparation
