Abstract

The invention discloses an alcohol-soluble electromagnetic wave shielding coating, which comprises the following components by weight percentage: 20-50 percent of conductive powder, 25-45 percent of conductive resin, 0.5-2 percent of coupling agent, 2-4 percent of dispersing agent, 0.5-3 percent of alignment agent and 17-50 percent of alcohol solvent. The invention aims to overcome the defects ofthe domestic electromagnetic wave shielding coating at present, and provides a coating which can shield electromagnetic waves and effectively reduce the electromagnetic radiation pollution.

Description

technical field [0001] The invention relates to an alcohol-soluble electromagnetic wave shielding paint. Background technique [0002] With the market popularization of consumer electronic products such as mobile phones, TV sets, DVD players, personal computers, digital audio-visual, electronic games, automotive electronics, microwave ovens, and digital cameras, as well as the development of the electronic information industry and the development of high-tech, high-power electronic appliances The wide application of equipment has formed complex electromagnetic environmental pollution. Moreover, the electromagnetic energy radiated by electromagnetic waves is increasing at a rate of 7%-14% per year, and electromagnetic environmental pollution is becoming more and more serious. Electromagnetic radiation pollution has become the fourth largest social public hazard after air pollution, water pollution, and noise pollution.
