Integrated nano-toughened PA6 nanocomposite material

The invention discloses an integrated nano-toughened PA6 nanocomposite material. The integrated nano-toughened PA6 nanocomposite material comprises the following raw materials in parts by mass: 70-90 parts of PA6, 10-20 parts of PE, 0.5-5 parts of maleic anhydride, 0.1-0.3 part of an antioxygen, 0.05-0.1 part of a catalyst I, 0.05-0.1 part of a catalyst II and 1-3 parts of nanoemulsion, wherein the nanoemulsion is prepared in the following steps: 1), adding 1-3 parts of nanopowder into a coupling agent solution, and uniformly mixing; 2) regulating pH to be 6.5-7.5; 3) performing ultrasonic dispersion into the uniform emulsion. Through integral formula design, the catalyst I and the catalyst II are introduced into a system; in the preparation process of the composite material, in-situ grafting can be achieved; through cooperation of a matrix and various functional auxiliary agents, the toughness of nylon is greatly improved.
