Problems solved by technology

Although existing inorganic metal antibacterial coatings have antibacterial properties, such as using nano-silver as a bactericidal component, the antibacterial time is short, prone to oxidation and loss, and is easy to be stained with dust, easy to absorb water and deteriorate, low in hardness, easy to damage, easy to fall off, and Environmental performance is poor
Traditional fungicides usually contain toxic substances, which will produce carcinogens that are harmful to the human body after application

The present invention provides an antibacterial dressing, which comprises an agent A and an agent B, wherein the agent A comprises a fluorocarbon resin, a dispersant, polyethylene glycol, polyisocyanate, tetraethylene glycol and a nano-titania sol, and the agent B comprises nano-scale hydroxylated polystyrene microspheres, glycidol, a glycidol-based epoxy resin, triethylamine, and diethylene glycol diethyl ether.

Description

technical field [0001] The invention relates to an antibacterial dressing. Background technique [0002] With the advancement of science and technology and the rapid development of modern industry, environmental problems are becoming more and more serious. Human beings pay more attention to health. With the gradual improvement of environmental protection awareness, the demand for antibacterial of architectural glass and walls is becoming more and more urgent. Although existing inorganic metal antibacterial coatings have antibacterial properties, such as using nano-silver as a bactericidal component, the antibacterial time is short, prone to oxidation and loss, and is easy to be stained with dust, easy to absorb water and deteriorate, low in hardness, easy to damage, easy to fall off, and Environmental performance is poor. Traditional fungicides usually contain toxic substances, which will produce carcinogens that are harmful to the human body after application. Contents ...
