Abstract

The invention provides a corrosion-resistance electromagnetic shielding material. The material is prepared from the following raw materials in parts by weight: 60-100 parts of a plastic substrate, 15-30 parts of isocyanate, 5-10 parts of carbon fibers, 3-8 parts of wood fibers, 5-15 parts of a nano-magnetic metal material, 3-10 parts of silicon dioxide, 2-5 parts of a dispersing agent, 3-10 parts of plasticizer, 2-5 parts of a lubricating agent, 2-6 parts of a coupling agent and 1-3 parts of color masterbatch. The plastic material has excellent electromagnetic shielding effect and excellent corrosion resistance, has good mechanical performance and strong impact resistance, can be used for protecting healthy of human bodies, and is long in service life and simple in preparation method.

Description

technical field [0001] The invention relates to the technical field of electronic materials, in particular to a corrosion-resistant electromagnetic shielding material. Background technique [0002] With the development of science and technology, various high-frequency electromagnetic wave devices and instruments such as radars, satellites, microwave ovens, and mobile cordless phones are widely used, making the earth space full of electromagnetic waves of various frequency bands. These electromagnetic waves will affect other electromagnetic instruments. While causing interference, it also affects human health. According to reports, working in front of a computer for more than 6 hours a day will cause irreversible damage to human skin due to electromagnetic radiation; electromagnetic wave intensity tests have shown that mobile communication equipment has great damage to human reproductive and memory functions. Electromagnetic wave pollution has become the fourth largest pollu...
