Problems solved by technology

[0006] In order to overcome the defects in the prior art that the anti-virus effect of the coating is poor, it is difficult to adapt to various application places, and it is difficult to have a sustained and effective anti-virus effect, the primary purpose of the present invention is to provide an anti-virus coating. It has anti-virus effect and improves the anti-virus effect, which can reduce the probability of cuprous ion being oxidized, and can also reduce or even prevent the problem of precipitation, discoloration, and failure of the coating. In this way, the coating is easy to form a stable system, and Improve the continuous effectiveness of the anti-virus effect; in addition, the coating can kill the virus adsorbed on the wall, reduce the risk of transmission, and is also suitable for a variety of applications

Abstract

The invention discloses an antiviral coating and a preparation method thereof, and relates to the technical field of coating. The antiviral coating comprises the following components by weight: 10-30parts of a solvent, 0.5-1.5 parts of a copper-containing compound capable of generating cuprous ions, 25-35 parts of an EVA / vinyl acetate-acrylic water-based emulsion, 1.7-4 parts of an auxiliary agent, 17-25 parts of a pigment and 15-25 parts of filler; the copper-containing compound is treated with an acidic solution prior to addition. According to the present invention, the coating has antiviral effect, improves the antiviral effect, reduces the cuprous ion oxidation probability, and reduces or even is free of precipitation, color change, failure and other problems, therefore, the coating easily forms a stable system, and the lasting effectiveness of the antiviral effect is improved; besides, the coating can kill viruses adsorbed on the wall surface, reduces the propagation risk, and isalso suitable for various application places; the preparation method is simple, no excessive pollutant is generated in the whole process, and the operation safety can be improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an antiviral coating that can be applied to walls and a preparation method thereof. Background technique [0002] In recent years, pathogenic viruses caused by various influenza or coronaviruses have had a great impact due to their ease of transmission, such as crowding out medical resources and posing serious challenges to public health. Virus infection is the main cause of human illness, and one of the common ways of virus transmission is indirect contact transmission, such as elevator buttons, door handles, walls, etc. Disinfecting public spaces and indoor environments with disinfectants such as disinfectant alcohol and sodium hypochlorite is an effective way to reduce the spread of viruses, but this method is difficult to adapt to a variety of applications due to the short effectiveness of disinfectants Sustained and effective antiviral effect. [0003] Some metal inorgani...
