Abstract

The invention discloses an antibacterial and antiviral microcapsule as well as a preparation method and application thereof. The antibacterial and antiviral microcapsule is a composite microcapsule which takes an antibacterial and antiviral effective component as a core material and synthetic resin as a shell material, and the surface of the composite microcapsule is modified with functional chemical groups. The preparation method comprises the following steps: preparing the core material containing the antibacterial and antiviral effective components; preparing microcapsules by taking synthetic resin as a shell material; and carrying out surface modification on the prepared microcapsule. The antibacterial and antiviral effective components, the synthetic resin and the functional chemical groups are creatively combined, and long-acting controlled release of the loaded antibacterial and antiviral effective components is realized through a synergistic effect; the prepared antibacterial and antiviral microcapsule has good adhesion capacity and wide application range, has contact killing and anti-adhesion effects on various microorganisms, and can keep the surface of an attached object clean; meanwhile, the microcapsule has good biocompatibility and long-acting antibacterial and antiviral effects; and a new strategy can be provided for public health safety protection.

Description

technical field [0001] The invention belongs to the field of manufacturing special chemical products, and in particular relates to an antibacterial and antiviral microcapsule as well as a preparation method and application thereof. Background technique [0002] In recent years, infectious diseases have spread faster than ever before, according to the World Health Organization (WHO). [0003] The mutation of viruses with different environments has become one of the thorny problems that are difficult to control. Therefore, it is particularly important to take preventive measures against pathogenic microbial infection, especially in densely populated urban areas. How to prevent the generation, reproduction and spread of pathogenic microorganisms has become one of the main issues of public health security. Killing pathogenic microorganisms, reducing the reproduction of pathogenic microorganisms or blocking the spread of pathogenic microorganisms is the key link to achieve the ...
