Abstract

The invention discloses antiviral flame-retardant weather-resistant coating. The coating is characterized in that the coating comprises, by weight, 2 to 5 parts of epoxy hexamethylene tetramine salt,30-40 parts of a 4-propenylthiosemicarbazide / 1-allyl-3-methylimidazolium chloride / zeatin nucleoside / isobornyl acrylate copolymer, 5-8 parts of modified Ti-Cu-Hf-O, 1-3 parts of antiviral Chinese herbal medicine powder, 10-15 parts of an inorganic filler, 10-15 parts of a solvent, 1-3 parts of a dispersing agent and 0.5-1.5 parts of a defoaming agent. The invention also discloses a preparation method of the antiviral flame-retardant weather-resistant coating. The antiviral flame-retardant weather-resistant coating disclosed by the invention is excellent in comprehensive performance, remarkablein antiviral effect, good in weather resistance and flame resistance, high in bonding strength with a base material and long in service lifetime.

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 ...
