Abstract

The invention relates to the field of building coatings and provides a water-based conductive electromagnetic shielding building coating based on graphene. The defects that a coating in the prior art is poor in electromagnetic wave shielding performance in the frequency bands of 100 KHz to 1 GHz, short in expiry date, poor in adhesive force for a base material and poor in cold and hot cycle resistance are overcome. The water-based conductive electromagnetic shielding building coating is prepared from, by weight, 1-3 parts of antifreezing agent, 0.1-0.2 part of neutralizer, 0.1-0.3 part of wetting agent, 0.1-1 part of dispersant, 0.1-0.5 part of defoamer, 1-5 parts of graphene, 35-50 parts of calcium carbonate, 0.1-0.3 part of preservative in a tank, 0.1-0.3 part of dry film mould-proof anti-algae agent, 1-3 parts of coalescing agent, 1-2 parts of thickener, 15-25 parts of emulsion and the balance deionized water.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a graphene-based water-based conductive electromagnetic shielding architectural coating and a production method thereof. Background technique [0002] With the rapid development of modern technology, various electronic devices and household appliances are used more and more, and these devices and appliances will produce different degrees of electromagnetic radiation. Electromagnetic radiation not only causes mutual interference between radiation sources, but also pollutes the living space of human beings. The compilation team of <<Residential Building Code>>, which came into effect on March 1, 2006, clearly pointed out in the key points: "Electromagnetic pollution has been recognized as the fourth largest public hazard after air pollution, water pollution, and noise pollution. The United Nations Conference on the Human Environment has listed electromagnetic radi...
