Permanent antistatic PA56 material and preparation method thereof

The invention discloses a permanent antistatic PA56 material and a preparation method thereof. The PA56 material comprises the following components in parts by weight: 83.9-98.9 parts of PA56 resin, 10-15 parts of a polyether antistatic agent, 2-3.5 parts of carbon nanotubes, 0.3-0.5 part of a coupling agent, 0.2 part of an antioxidant, 0.4 part of a lubricant and 0.5 part of color master batch. The polyether type antistatic agent is adopted to carry out antistatic modification on the PA56 resin, so that the antistatic system of the modified PA56 material can be effectively reduced. Meanwhile, carbon nanotubes with good conductivity are introduced to be compounded with the polyether type antistatic agent for use, and in the preparation process, the unique multi-wall tubular structure of the carbon nanotubes and the polyether type antistatic agent further form a mutually-contacted network, so that the antistatic property of the PA56 material is further improved; meanwhile, the higher Young modulus of the carbo
