Embodiment 1

[0026] Weigh 600 grams of polyamide fiber and dry it at 90°C for 4 hours, then mix it with 80 grams of vanadium dioxide, 130 grams of tin dioxide, 50 grams of γ-aminopropyltriethoxysilane, methyl methacrylate-butylene 50 grams of diene-styrene copolymer and 8 grams of monoglyceride stearate were stirred for 5 minutes at 1100 rpm in a high-speed mixer, and released after being uniform. Put the mixed material into the twin-screw extruder with a length-to-diameter ratio (L / D) of 40. The processing temperature of the twin-screw extruder: the temperature in the first zone is 180°C, the temperature in the second zone is 185°C, and the temperature in the third zone is 180°C. The temperature of the fourth zone is 195°C, the temperature of the fourth zone is 210°C, the temperature of the fifth zone is 215°C, the temperature of the sixth zone is 225°C, the temperature of the seventh zone is 235°C, the temperature of the eighth zone is 240°C, and the speed of the main engine is 320 rpm; ...

Embodiment 2

[0028] Conductive nylon was prepared in the same manner as in Example 1 except that vanadium dioxide was not used.

Embodiment 3

[0030] Conductive nylon was prepared in the same manner as in Example 1 except that tin dioxide was not used.

Abstract

The invention relates to a preparation method of a conductive nylon. The preparation method comprises the following steps of: weighing a polyarmide fiber, drying for 4h under the temperature of 90 DEG C, stirring with vanadium dioxide, stannic oxide, an interface coupling agent, a toughening agent and a dispersing lubricant by 1100 turns / min in a high-speed stirrer, and discharging after uniforming; adding the evenly-mixed material into a twin-screw extruder of the which the length-diameter (L / D) ratio is 40, wherein the machining temperature of the twin-screw extruder is as follows: the temperature of a first region is 180 DEG C, the temperature of a second region is 185 DEG C, the temperature of a third region is 195 DEG C, the temperature of a fourth region is 210 DEG C, the temperature of a fifth region is 215 DEG C, the temperature of a sixth region is 225 DEG C, the temperature of a seventh region is 235 DEG C, the temperature of an eighth region is 240 DEG C, and the rotation speed of a main machine is 320 turns / min; cooling a check rod after extruding, and dicing in an air drying way to prepare the conductive nylon. The electrical conductivity of the nylon prepared by the method provided by the invention can be greatly improved.
