Abstract

The invention discloses a preparation method and application of an indoor coating additive with an antiviral effect. The broken coordination bond can make the desorbed organic virucidal agent contact with infectious virus, and the virus can be killed. In this process, the organic virucidal agent itself is also consumed. However, the slow release is realized during the desorption process, thereby realizing the long-term effectiveness of the virus killing performance.
