Description

Floor material utilizing earth

The present invention relates to a flooring material using soil, and in particular, by including the soil on the top of the printing layer, the transparent layer or the base layer, or the bottom of the base layer, the natural natural texture of the soil is matched with the printed pattern, and the predetermined When heat is supplied, the soil contained is absorbed by the slowly released into the far infrared, and the flooring material is able to achieve the warming effect.

In general, flooring is used to decorate living spaces beautifully as a finishing material for indoor floors or furniture of buildings, and once installed on a building floor, it has to be used for a long time. Durability that is not easily damaged by water and water is required to prevent liquid contaminants such as water from penetrating, and it has a beautiful interior decoration effect to decorate the building beautifully and not only satisfy the aesthetic sense of various users. Even if it is installed for a long time, it is required to have a subtle aesthetic so as not to cause boredom.

However, PVC decorative material, which is conventionally used flooring material, as shown in Figure 3, the foamed or non-foamed layer 21 on top of the substrate layer 20 processed by using a glass fiber or mineral paper, a vinyl chloride resin on the imitation paper And a printing layer 24 formed on top of the printing layer 24 to form a predetermined pattern by printing using a gravure or rotary screen method, a transparent layer 26 coated on or laminated on the printing layer 24, a UV layer 28, and It is comprised by the back layer 22 laminated | stacked under the base material layer 20. As shown in FIG.

In this case, the surface layer stacked on the base layer 20, that is, the foamed or non-foamed layer 21, the printed layer 24, the transparent layer 26, the UV layer 28, or the back layer below the base layer 20. (22) is added to the base layer 20 by appropriately adding or subtracting to give various functions such as cushioning or waterproofing, durability, stain resistance, abrasion resistance, sound insulation effect, etc. required according to the use of the flooring and the installation place. Although it is to be laminated, there was a problem that it is difficult to expect the warming effect to maintain the heat inside the building for a certain period.

In order to express a predetermined decorative effect, any one of the foamed or non-foamed layer 21, the printed layer 24, the transparent layer 26, and the UV layer 28, which are surface layers stacked on the base layer 20, is laminated. Although the pattern is printed on the above layer with a conventional pigment, the pattern according to the conventional printing method is difficult to express the natural color and texture, so that the decorative effect as expected can not be achieved, and also by the artificial decorative effect There was a problem such that the buyers get tired immediately.

In order to solve the above problems, the present invention provides natural texture and color to the pattern printed on the upper part of the base layer to obtain excellent decorative effect, while maintaining the heat inside the building for a long time effectively. The purpose is to provide a flooring that can be insulated.

The flooring material of the present invention for achieving the above object, in the flooring material consisting of a base layer and a surface layer laminated on top of the base layer to add functionality and decoration, to include a predetermined natural soil in the surface layer or the back layer. It is characterized by.

At this time, the soil is silicon dioxide (SiO ₂ ), aluminum oxide (Al ₂ O ₃ ), iron oxide (Fe ₂ O ₃ ), magnesium oxide (MgO), calcium oxide (CaO), potassium oxide (K ₂ O), water and It is composed of other materials, the particle size is preferably 0.1 to 300㎛.

According to the present invention described above, the natural texture and natural color of the soil contained in the surface layer is in proper harmony with the printed pattern of the print layer included in the surface layer can achieve a subtle printing effect, as well as the position of the surface layer of the soil included Accordingly, there is an effect that can express a variety of depth and printing effect of the printed pattern.

In addition, when a predetermined amount of heat is supplied to the flooring material, the soil contained therein absorbs it and is gradually released into the far infrared ray, so that the inside of the building can be warmed for a long time.
