Abstract

The present invention is a floor decorative material in which a negative ion is generated continuously and semi-permanently without a separate negative ion generating device by containing a powder generating an anion in any one or two or more layers of the floor decorative material.

Description

Floor decoration material with anion effect

TECHNICAL FIELD The present invention relates to a floor covering, and more particularly, to a floor covering including a powder generating anion in one or more layers (hereinafter referred to as "anion powder").

As is well known, air is made up of positive and negative ions, and their equilibrium is maintained in nature, but cations are generated due to air pollution and the use of household appliances in homes, causing the equilibrium to break and turbid air. At this time, the positive ions act on the body to increase respiratory rate and cause insomnia, headache, discomfort, and increased blood pressure. Anions, on the other hand, are known to have the effect of eliminating phlegm, preventing itching and excessive sweating, and improving appetite, sound sleep, and lowering blood pressure. In addition, medically anion is dissolved in blood when inhaled to increase the activity of the cells constituting the living tissue and to facilitate the metabolism of the transport and exchange of electrolytes and waste products such as sodium and potassium through the cell membrane.

As a method of generating such anions, there were anion cleaners and cleaners using conventional mechanical methods, but there was a problem in that they had to be continuously operated to obtain anion effects continuously.

Therefore, the present invention is to contain an anion powder composed of natural minerals in any one layer or two or more layers of the floor decoration material so that the anion is generated continuously, semi-permanently without a separate anion generating device.
