Embodiment Construction

[0026] Below in conjunction with embodiment the present invention is described in further detail.

[0027] The long-acting antibacterial composition of this embodiment is a sol-gel coating solution, which can be widely used in various industries that require sterilization, and the coating can be easily transferred to new purposes. Based on the fact that the antibacterial agent of the present application maintains high activity under both dry and wet conditions, the scope of application of the coating solution is broadened. The coating can also be applied to complex shaped surfaces.

[0028]Especially the hospital and the food industry use the coating solution of this embodiment very advantageously. In hospitals, coatings are used on all surfaces requiring antimicrobial protection, including walls, doors, floors, and various furniture and equipment. In the food industry, as a further improvement, for example, the shelf life of food, since the food is not exposed to microorgan...

Abstract

The invention relates to a long-acting disinfection antibacterial composition. The composition is a sol-gel coating liquid capable of forming an antimicrobial film on the surface of the substrate and comprises a bactericide, a binding agent, a curing agent, a stabilizer, solvent and water, the bactericide is linked to the surface of the substrate by the binding agent, and when the coating layer is applied to the substrate, the stabilizer and the solvent volatilize, the binding agent is formed into film by the curing agent, and the thickness of the film is adjusted according to the concentration and the use amount of the solvent; the bactericide is polyguanidine, polyguanidine salt or a mixed salt thereof, and the binding agent is organic silicon or organic silicon and organic molecules added based on the use and function of the coating. The time of the biocide continuously acting on the substrate and the antimicrobial effect can be obviously improved, even though the amount of the biocide is only very small.

Description

technical field [0001] The present invention relates to a coating solution applied to a substrate surface capable of forming an antimicrobial sol-gel coating covering the substrate surface. Furthermore, the present invention relates to methods for forming antimicrobial sol-gel coatings onto substrates, and methods for regenerating the antimicrobial activity of coatings on substrate surfaces. Background technique [0002] It is convenient and very important to clean various surfaces and form surface coatings to have an antimicrobial effect, such as hospitals, food industry, public catering services and in different public facilities. In the past, easy-to-clean surfaces have been achieved by using low surface energy coatings, for example by different fluorochemicals, (PTFE, Teflon) wax silicones. These cleanability-enhancing compounds have long been used in a variety of coatings. Various active ingredients, such as biocides silver, titanium oxide are also added to the paint ...
