FIELD: polymer production.
SUBSTANCE: development of polymer nanocomposites and the production of machine parts based on them, such as plain bearings, guide bushings, products for the brake system. A polymeric nanocomposite material is described, including polyoxymethylene with a melt flow index of 27 g/10 min, carbon nanotubes and a lubricant, characterized in that TUBALL MATRIX 815 dispersion is used as carbon nanotubes, and paraffin oil can be used as a lubricant in the following ratio of components, wt.%: polyoxymethylene 94-99, dispersion TUBALL MATRIX 815 1-5, paraffin oil 0-1. A method for obtaining the above polymeric nanocomposite material, including compounding on a twin-screw co-rotating extruder of polyoxymethylene, carbon nanotubes and a lubricant, as well as injection molding, characterized in that the components are pre-mixed in a drum tumbler type mixer, compounding on a twin-screw co-rotating extruder is carried out at a temperature of 175°C, the speed of rotation of the screws is 200 rpm, and injection molding is carried out at a temperature of 175-180°C and an injection rate of 12.9 ml/s.
EFFECT: improved elastic-strength characteristics, namely, increased strength and tensile modulus of elasticity of the material, as well as improved manufacturability.
