Problems solved by technology

At present, the antibacterial and antiviral coatings on the market generally use organic antibacterial agents or add nano-metal oxides, both of which have deficiencies, or have relatively harsh requirements for the use environment, or need to trigger photocatalysis in an environment with sufficient light, and The amount added per unit is large and sensitive to pH, so it cannot meet the actual needs

Abstract

The invention belongs to antibacterial and antiviral coatings, and discloses a Chinese mugwort-containing antibacterial and antiviral water-based coating and a preparation method and application thereof. The antibacterial and antiviral water-based coating comprises an antibacterial and antiviral composition, and the antibacterial and antiviral composition comprises a component A and a component B. The component A comprises a Chinese mugwort extract, an eucalyptus extract and a stigma croci extract. The component B comprises nano-silver ions and iChem powder. The component A and the component B can realize synergistic interaction, so that the antibacterial and antiviral performance of the coating is higher than that of a coating obtained by adopting a single component, harmful organic matters such as formaldehyde and acetaldehyde generated indoors can be removed, bacteria and viruses in the environment can be effectively killed, and the validity period can reach several years. The coating can be widely applied to the field of buildings, in particular to decoration spraying of various interior wall surfaces and the like.

Description

technical field [0001] The invention belongs to the technical field of antibacterial and antiviral coatings, and in particular relates to an antibacterial and antiviral water-based coating containing Artemisia argyi and its preparation method and application. Background technique [0002] Paint is a chemical mixture that can firmly cover the surface of the applied object for protection, decoration, marking and other special purposes. It was also called paint in the old days, because most of the early paints were made of vegetable oil. Coatings are due to the development of modern petrochemical industry, and chemical products emerge in endlessly. Modern coatings have broken away from the tradition of using oil to produce paint. More and more coating products are prepared through chemical synthesis. The meaning of paint is broader than that of paint, including more technological components. However, some colloquial and habitual names of paint are still reserved among the peo...
