Permanent conductive nylon plate and preparation method thereof

The invention discloses a permanent conductive nylon plate, which relates to the field of conductive materials. The preparation method comprises the following steps that raw materials are weighed in percentage by mass, and surface pretreatment is carried out on the conductive carbon material micro-sheets through a silane coupling agent; the above raw materials are input into a conical stirring barrel for stirring, and the stirred materials are poured into a double-screw rod for first-pass granulation; the granulated particles are poured into a hot air stirring barrel to be uniformly stirred through a filter screen; second-time granulation is conducted on the dried materials, and then through the filter screen, the particles subjected to secondary granulation are made into plate material through a single-screw extruder. The invention is advantageous in that the selected conductive carbon material micro-sheets are in the shape of concentrated particles, which are not easy to fly during use; compared with the tr
