Description

Technical field

[0001] The invention relates to the technical field of coatings, in particular to an anti-virus, flame-retardant and weather-resistant coating and a preparation method thereof. Background technique

[0002] In recent years, the emergence of highly pathogenic viruses such as influenza virus and enterovirus and some bacteria that are highly resistant to common fungicides have made public places such as hospitals, schools and other crowded places extremely vulnerable to outbreaks. In places with sexual diseases, especially in public health facilities such as hospitals, the possibility of the emergence of viruses and germs is extremely high, which is harmful to public health. Especially with the extensive development of modern industry, the environmental air quality is poor, and the number of people who suffer from viral infections is huge each year. In the season of high incidence of viral infections, students are suspended due to the virus and workers are suspended ...
