Abstract

The invention provides a water-based paint capable of shielding Wi-Fi signals as well as preparation and application methods thereof. The water-based paint is composed of the following components in parts by weight: 100 parts of water-based latex, 20-150 parts of nickel powder, 10-100 parts of conductive carbon black, 50-200 parts of deionized water, 3-15 parts of flatting agent, 2-10 parts of water-based conductive agent and 2-10 parts of dispersant. The preparation and application methods of the water-based pain comprise adding the dispersant, the nickel powder and the flatting agent to the water-based latex and stirring and dispersing by using a high-speed stirrer for 5-30 minutes firstly, next, adding the conductive carbon black, the deionized water and the water-based conductive agent to the slurry and dispersing to obtain the even water-based paint under the stirring of the high-speed stirrer, and then evenly applying the water-based paint to the surface of a substrate and drying. The water-based paint is pollution-free and capable of shielding Wi-Fi signals, has the advantages of good texture, wear resistance, scrawling prevention and the like, and can be widely applied to multiple fields.

Description

technical field [0001] The invention belongs to the field of water-based coatings, in particular to a water-based coating for shielding Wi-Fi signals and its preparation and use methods. Background technique [0002] In recent years, with the rapid development of my country's economy and the improvement of people's living standards, consumer electronics products such as mobile phones, televisions, personal computers, video games, automotive electronics, microwave ovens, and digital cameras have been widely used. The development of industry and the wide application of high-tech and high-power electronic and electrical equipment have caused electromagnetic waves to fill our living environment, making electromagnetic wave pollution another major public hazard after air pollution, water pollution, and noise pollution. Wi-Fi signals, etc. propagate through the air in the form of electromagnetic waves, so that electronic devices such as mobile phones, computers, and tablet computer...
