Electromagnetic shielding material, preparation method thereof and cable protection tube produced by electromagnetic shielding material

Abstract

The invention relates to the technical field of cable materials, in particular to an electromagnetic shielding material, a preparation method thereof and a cable protection tube produced by the electromagnetic shielding material. The electromagnetic shielding material comprises the following raw materials in parts by weight: 75-100 parts of PVC resin, 12-18 parts of an electromagnetic shielding material, 15-20 parts of a flame retardant, 8-12 parts of a synergistic flame retardant, 10-15 parts of an impact resistance agent, 12-18 parts of a coupling agent, 5-15 parts of a compatibilizer, and 6-10 parts of acrylate fiber, wherein the electromagnetic shielding material is a polyaniline-graphene oxide composite material. The PVC material of the invention has better properties of flame retardancy, impact resistance, weather resistance, tensile strength and hardness. The electromagnetic wave is reflected by utilizing the high conductivity properties of polyaniline, the high absorbing properties of graphene oxide is combined to absorb electromagnetic waves, so that the PVC material has excellent electromagnetic shielding effect.

Description

technical field [0001] The invention relates to the technical field of cable protection tube materials, in particular to an electromagnetic shielding material, a preparation method thereof, and a prepared cable protection tube.

Problems solved by technology

[0003] However, electromagnetic radiation can easily affect human health, especially the health of fetuses and young children. Long-term exposure to electromagnetic radiation can induce cancer, such as leukemia, and become the cause of many diseases; The ground passes through the plastic protective shell to generate interference, which interferes with electronic devices such as instruments and meters, and interferes or hinders the normal functions of electronic devices, resulting in inability to use them normally, especially in the fields of aviation flight and medical equipment, which require high precision instruments. In the field, the electromagnetic interference generated by the cable will affect the normal operation of the instrument and easily affect the flight safety of aviation and the accuracy of medical equipment.
