The invention relates to a chemical material, in particular to an electromagnetic shielding material and a preparation method thereof. The preparation method of the electromagnetic shielding material comprises the following steps of: after mixing, heating and preprocessing ABS plastics and an ABS plasticizer, adding conductive carbon black, magnetic powder and carbon fibre, mixing evenly by a high mixing machine, then delivering into a twin-screw extruder, extruding and granulating so as to prepare the electromagnetic shielding material; and the invention has favorable effect of preventing the radiation of electromagnetic waves and can be applied to the fields of electric power, wireless communication, household appliances and military affairs. The invention has extensive application, simple process and low manufacturing cost and can be recycled.
Description
technical field The invention relates to a chemical material, in particular to an electromagnetic shielding material and a preparation method thereof. Background technique With the improvement of living standards, more and more electrical products have entered the family. These electrical appliances will more or less produce electromagnetic radiation. Electromagnetic radiation exceeding 2 milligauss will cause people to suffer from diseases. Thermal effects, non-thermal effects and cumulative effects on the human body have caused more and more people in a modern sub-health state. The radiation pollution of household appliances should get more and more attention. At present, most of the electromagnetic shielding materials used at home and abroad are made of metal materials. Its purpose is to attenuate electromagnetic radiation, but its equipment investment is large, the process is complicated, and the product price is too high.
