Description

POLY VINYL CHLORIDE BASED DECORATIVE FLOORING COVER COMPRISING AROMATHERAPY FUNCTION}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to flooring materials, and more particularly to a polyvinyl chloride (PVC) -based flooring material containing an aromatherapy function.

Aromatherapy is the use of essential oils derived from the flowers, leaves, stems, roots, and fruits of plants to achieve a positive effect on the body and mind. It was in the twentieth century that this aromatherapy was scientifically studied and attracted attention as an area of alternative medicine. But healing with fragrance began in the temple of Egypt more than 6,000 years ago. Egyptian priests studied fragrances and used them to treat rituals and diseases in honor of the gods. In Egyptian pyrides, there are many paintings showing the widespread use of aromatic fragrances and medicines. The mummies can remain until thousands of years later because they use a very strong antiseptic.

On the other hand, architectural flooring is a practical living space for humans, so the role of flooring, which was only the floor finishing material of the conventional simple building, is required for various functionalities and decorativeness as the living standard and living environment are improved.

Typical PVC-based flooring materials include a sizing layer 32, a foaming layer 31, a base layer 10, a foaming layer 21 or a non-foaming layer 22, a printing layer 23, a skin layer 24, and the like from the bottom. The surface treatment layer 25 has a sequential structure. In addition, various types of flooring materials are known to increase the health of users living in the flooring material by adding an antimicrobial agent and far-infrared ray emitting material to the flooring material.

Recently, researches on ways to enhance the activation of biological activity of the human body have been actively conducted. Accordingly, researches on geomagnetic compensation, water-wave blocking, and far-infrared emission have been conducted.

However, as described above, researches for developing beneficial properties for the human body continue, but many points are found to be insufficient to impart health functionalities.

In view of the problems of the prior art, an object of the present invention is to provide a flooring material having an aromatherapy function in a polyvinyl chloride-based flooring material comprising a plurality of layers.

Another object of the present invention is to provide a flooring material that can continuously provide effects such as stress reduction, soothing, vitality enhancement.

In order to achieve the above object, the present invention provides a polyvinyl chloride-based floor covering comprising aromatherapy material in at least one layer in the polyvinyl chloride-based floor covering containing a plurality of layers.

Hereinafter, the present invention will be described in detail.

The present invention is added to any one layer of polyvinyl chloride flooring material containing a plurality of layers of aromatherapy functional material known to be beneficial to health, so that the aromatherapy material is gradually volatilized during use as a flooring material, volatilized aromatherapy material It is intended to show the effect of stress reduction, calming, and vitality to this user.

The aromatherapy functional flooring material according to the present invention is, for example, from the bottom, the sizing layer 32, the foam layer 31 to impart a cushion feeling, the base layer 10 to impart dimensional stability, the foam layer 21 to impart a cushion feeling ), A print layer 23 having a predetermined pattern and color to impart decorativeness, a skin layer 24 so that the print layer 23 is visible while protecting the print layer, and a scratch prevention of the surface And an aromatherapy material in at least one layer of the conventional vinyl chloride-based flooring material as shown in FIG. 1 having a sequential structure as the surface treatment layer 25 to improve the stain resistance. Specifically, the aromatherapy material is contained in the surface treatment layer 25 as shown in the example of FIG. 2. In addition, as shown in FIG. 3, the skin layer 24 may contain an aromatherapy material. However, it may be added to any one of the foamed layer 21, the non-foamed layer 22, the base layer 10, the foamed layer 31, the sizing layer 32, etc., and may be added to all of these layers at the same time. have.

The aromatherapy functional material 40 is used as plant essential oils or animal extracts. Preferably, as essential oils of plants, lavender, cypress, jasmine, rosemary, pine, peppermint, etc. may be used, and musk may be used as an extract of an animal. In addition, the essential oil of the plant or the extract of the animal can be used alone or in combination depending on the required function.

The aromatherapy functional material 40 of the present invention may be directly contained in each layer, and may be contained after processing the aromatherapy functional material 40 in various ways in order to maintain its persistence.

One of the processing methods is to encapsulate the aromatherapy functional material 40 in each layer. Encapsulation is to completely wrap the resin component in the solid or liquid aromatherapy functional material by spray drying, interfacial polymerization, phase separation, polymerization, or the like. For example, the phase separation method microencapsulates the red product of the aromatherapy functional component by using a resin containing a large amount of lipophilic groups and hardens it, and then uses a solvent substitution method or the like to obtain a liquid oily substance. It is prepared by suspension or by drying in powder form using a spray drying facility.

Another processing method may be used by impregnating the aromatherapy functional material 40 in the porous material. In this case, the porous material that can be used may include porous silica, diatomaceous earth, and the like.

The aromatherapy functional material 40 preferably contains 0.1 to 7% by weight based on the containing layer. If it is less than 0.1% by weight, the aromatherapy function is weak, and if it exceeds 7% by weight, the effect as much as the added amount does not appear.

The aromatherapy functional flooring material of the present invention is absorbed by the user as the aromatherapy functional material 40 contained in at least one layer is gradually volatilized to impart a unique function of the aromatherapy functional material 40. The flooring material manufactured in this way has the effects of stress reduction, soothing, and vitality, which are inherent functions of the aromatherapy functional material.

The present invention will be described in more detail with reference to the following examples. However, an Example is for illustrating this invention and is not limited only to these.
