A stop layer and an underlayer are respectively provided;

Due to the polyolefin-based environmentally friendly flooring material and a method of manufacturing the bottom layer of the configuration is provided with a balance layer, which is a processing sheet of the same material as the transparent upper layer of the surface layer;

In particular, it is harmless to the human body by the product composition of the non-toxic component composed of a polyolefin resin material of the present invention composition, and harmful substances such as environmental hormones and dioxins, which are problems of the vinyl chloride resin material flooring of the prior art, are not generated, and a plasticizer ( DOP) is not added to prevent sick house syndrome, which promotes the health of the human body

The present invention relates to a polyolefin-based eco-friendly flooring material and a method of manufacturing the same, which have enhanced weather resistance, flexibility, flexural strength, improved printability, beautiful appearance of flooring, and improved workability.

Recently, due to the improvement of living standards, the flooring material made of solid wood veneer on the floor of the building or the flooring material composed of a synthetic resin layer made of vinyl chloride resin (PVC) having excellent processability is widely used.

The vinyl chloride resin (PVC) is a material widely used in various fields due to its excellent workability.

However, since the vinyl chloride resin (PVC) contains a chlorine (Cl) component, a large amount of chlorine gas and smoke are generated during a fire, and at the same time, it is fatal to the human body. When incinerated, harmful substances that are dioxins are generated,

In addition, the plasticizer (DOP) added to the flooring material for processing the flooring material of vinyl chloride resin (PVC) generates VOC (volatile organic compound) and HCHO (formaldehyde), which are toxic substances that cause bird concentration syndrome. Is causing harmful problems,

Weather resistance and flexural strength due to the intrinsic physical properties of the vinyl chloride resin (PVC) is lowered, causing problems in product use.

In addition, as shown in FIG. 11, in order to improve the problem that is harmful to the human body caused by the use of the flooring material of the vinyl chloride resin (PVC) material as described above, some eco-friendly flooring materials using non-toxic polyolefin resin and registered a patent in Korea No. 10-0908661 (registered on July 14, 2009) registers "environmentally friendly flooring materials comprising copolymers containing propylene and ethylene and thermoplastic polyolefin-based materials and methods for producing the same".

However, the eco-friendly flooring material 200 using the eco-friendly flooring material using the non-toxic polyolefin resin of the prior art, the copolymer containing propylene and ethylene of the prior patent No. 10-0908661 and the thermoplastic polyolefin-based material 200 is By using non-toxic polyolefin resin such as flooring material, chlorine gas and smoke are prevented in case of fire, and it is safe to prevent accidents and harmful substances.

One of the advantages of polyolefin-based materials is that the unit specific gravity, which is one of the strengths, is reduced to reduce the weight that can affect the structure of the building compared to the existing polyvinyl chloride flooring. The disadvantages of many changes are overcome by the combination of additives in the manufacturing method and the improvement of the manufacturing process.
