Abstract

This invention discloses a method for manufacturing a polymer emulsion coating that can absorb electromagnetic waves, which adopts polymer emulsion as the coating material, and powders that can absorb electromagnetic waves and fibrous material as the fillers. Besides, film-forming assistant and surfactant are added to manufacture water polymer coating. After brushed or sprayed on the surface of architectures, the coating can form a coating layer. After vaporization of water in the coating layer, polymer particles interconnect with each other, and adheres the powders and the fibrous material to form a wave-absorption layer. The polymer emulsion coating in this invention has good electromagnetic wave-absorption property. The method has such advantages as simple process, easy operation and wide applications.

Description

technical field [0001] The invention relates to a polymer emulsion used as a film-forming material to prepare an electromagnetic wave-absorbing coating and a preparation method thereof. Background technique [0002] Environmental electromagnetic pollution caused by electromagnetic radiation affects human health, which has increasingly attracted the attention of various countries. With the enhancement of public awareness of environmental protection, the control of electromagnetic wave pollution will become one of the important contents of environmental protection. Within the range covered by electromagnetic radiation (public buildings, public places, residential areas, etc.), new environmentally friendly wave-absorbing materials are used to make the building itself have a certain electromagnetic wave absorption capacity, which can attenuate the intensity of environmental electromagnetic waves and effectively reduce electromagnetic environmental pollution. , to reduce the har...
