Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to the field of PA polymer materials, and in particular to a reinforced, toughened and anti-aging PA kaolin composite material and its preparation method and application. Background technique [0002] Polyamide (PA) is a commonly used plastic material, which has the advantages of good thermoplasticity, chemical corrosion resistance, and aging resistance. Compared with metal materials, PA has lower quality and is easier to process and shape. It is used in household appliances, It has a wide range of applications in the fields of automobile industry and aviation industry. In the above fields, PA is usually used to manufacture bearings, circular gears, cams, bevel gears, pulleys, pump impellers, fan blades, worm gears, propellers, screws, nuts, gaskets and other parts. However, PA has the disadvantages of low toughness and poor impact resistance, which seriously limit its ap...
