Continuous long conductive fiber filled electromagnetic shielding composite material and preparation method thereof

The invention discloses a continuous long conductive fiber filled electromagnetic shielding composite material. The material comprises the following components by weight: 64-88 parts of a thermoplastic resin, 10-33 parts of continuous conductive fibers, 0.5-0.7 part of an antioxidant, 0.3-0.5 part of a lubricant. The invention also discloses a preparation method of the above continuous long conductive fiber filled electromagnetic shielding composite material. Compared with a short fiber or conductive filler filled thermoplastic resin, the continuous long conductive fiber filled thermoplastic resin adopted by the invention requires less long conductive fibers to reach a same shielding effect, and has cost advantage; at the same time, the continuous long conductive fiber material provided by the invention has certain enhancement effect on the mechanical properties of material, and a small filling amount can maintain good mechanical properties of the material.
