Abstract

The invention discloses a novel antibacterial and antiviral multifunctional coating and a preparation method thereof. The novel antibacterial and antiviral multifunctional coating comprises a pure acrylic emulsion, hydroxyethyl cellulose, a silver-loaded antibacterial and antiviral material, an auxiliary agent, a filler and water; and the silver-loaded antibacterial and antiviral material comprises Ag2SiO3 powder with the particle size of 1-30 microns and Ag@Zr (HPO4) 2 powder with the particle size of 10-200 nm. According to the invention, Ag@Zr (HPO4) 2 powder with a small particle size fills Ag2SiO3 powder with a large particle size and a layered structure to prepare the silver-loaded antibacterial and antiviral material. Aggregation of small-particle-size Ag@Zr (HPO4) 2 powder can be prevented, and the silver-loaded antibacterial and antiviral material is applied to the coating, so that the novel antibacterial and antiviral multifunctional coating with excellent antibacterial and antiviral effects can be prepared.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a preparation method of a novel antibacterial and antiviral multifunctional coating and a novel antibacterial and antiviral multifunctional coating prepared by the method. Background technique [0002] Paint is a commonly used surface decoration material, which is widely used in vehicles, decoration, military, transportation, construction and other fields. Architectural coatings are one of the four major categories of products that chemical building materials focus on. The research and development of high-performance antibacterial coatings has received extensive attention from various countries. As the most commonly used building material, architectural coatings account for the majority of the coatings market. Driven by the concept of modern healthy consumption, with the improvement of living standards and weight, people gradually recognize the true meaning and use of antibacte...
