In addition, Korean Laid-Open Patent Publication No. 2000-0072510 provides a laminated flooring material using gold powder or silver powder, which relates to a synthetic resin flooring material using vinyl chloride resin as a main material.

This method provides a synthetic resin flooring material as described above by adding gold powder or silver powder to the top layer of the surface layer constituting the flooring material and the back functional layer of the backing layer using the synthetic resin corresponding to the main material. It is the content that antimicrobial which is inherent function of silver powder and shielding function of electromagnetic wave can be aimed at.

However, this is because the use of synthetic resin as a raw material as described above, there is a problem that can cause environmental pollution of the waste material, including the toxicity accordingly.

In particular, powdered silver has a problem in dispersibility and economical efficiency as well as causing surface discoloration compared to silver ionized water in aqueous solution.

The present invention provides a flooring board exhibiting antimicrobial activity, which is a function of silver in providing a wood flooring material.

In order to achieve this object, the present invention is to use the colloidal silver ion water prepared by the method of electrolyzing silver at a very high voltage in an aqueous solution.

In this case, the silver ionized water is used as a part of a composition composed of a thermosetting resin, a curing agent, a plasticizer, and a release agent to penetrate the overlay paper, the shape paper, and the back paper used in the present invention, and the wood, a high density fiber board (HIGH DENSITY FIBER BOARD) or It is characterized by providing an antimicrobial flooring board made of wood by adhering integrally to the synthetic wood, and also providing a flooring board manufactured by such manufacturing.
