Abstract

The invention relates to an antibacterial diatomite-based coating as well as a preparation method and application thereof, and particularly relates to an antibacterial coating for wallpaper, belonging to the field of coatings. According to the antibacterial diatomite-based coating, an antibacterial agent is loaded on a special porous structure of diatomite, so that the diatomite is endowed with antibacterial performance, and then the antibacterial agent-loaded diatomite, a dispersing agent, a defoaming agent, a water retaining agent, water and an adhesive are mixed and stirred to prepare the diatomite coating. According to the method, the antibacterial agent with excellent performance is used for replacing existing widely-used nanometer titanium dioxide; during implementation of the method, the antibacterial agent is good in bactericidal activity, broad-spectrum, long-acting, small in usage amount and low in price. The method is convenient and feasible, simple to operate without using special instruments and equipment, and easily produced industrially.

Description

technical field [0001] The invention relates to an antibacterial diatomite-based coating and its preparation method and application, in particular to an antibacterial coating for wallpaper, which belongs to the field of coatings. Background technique [0002] With the continuous improvement of people's living standards, the demand for wallpapers in the home decoration market continues to increase, and wallpapers with special properties have attracted more and more people's attention, and diatomite wallpapers with humidity-regulating functions have quietly emerged. Diatomite wallpaper has been widely used from public places of hotels and hotels to interior decoration of ordinary people's homes, which solves the problem of too humid or too dry indoor environment, reduces the use of humidifiers and dehumidifiers, and is environmentally friendly and low-carbon. In addition, many places currently put forward higher requirements for diatomite wallpaper, such as medical and sanitat...
