The invention provides a method for preparing a montmorillonite nylon 6 composite material. The method comprises the following steps: (1) adding aminocaproic acid into polyethylene glycol liquid, then, adding concentrated sulfuric acid, stirring, heating, and carrying out heat-preservation reaction, so as to obtain an aminocaproic acid-polyethylene glycol esterified substance which serves as a montmorillonite modifier; (2) modifying montmorillonite by using the montmorillonite modifier; (3) mixing nylon 6, modified montmorillonite, an antioxidant and an ultraviolet resisting agent, and granulating, so as to obtain nylon 6 slice particles; (4) drying the nylon 6 slice particles in a nitrogen-atmosphere dryer, carrying out solid-phase polycondensation, and then, cooling, thereby obtaining the montmorillonite nylon 6 composite material. According to the method provided by the invention, the raw materials for preparing the montmorillonite modifier are easily obtained, and the modification effect is good.
