Description

[Detailed Description of the Invention] The present invention relates to a floor covering, and particularly to a wide and long floor covering having a spine embossed pattern on its surface.

Wide and long sheet-like floor coverings have been widely used as building flooring and general household flooring.
Recently, highly decorative wide and long floor coverings with various uneven patterns and printed patterns on the surface of these sheets have been used.

Among these, the type that is particularly suitable for heavy walking is the sheet-like wide and long floor covering made of soft vinyl chloride resin with embossed spines, which provides a comfortable walking feel, wear resistance, and chemical resistance. Although it has excellent basic properties as a mat, there are various problems in terms of decoration, workability, and aesthetics.

That is, since the spine is embossed, deep drawings are provided on the sheet surface, but the deep drawings are likely to become clogged with mud carried by footwear such as shoes.

Remove these mud. In other words, when cleaning, the presence of this deep drawing makes it difficult to clean.

The sheet itself is stretched or meandered due to the heating during spine embossing, so when multiple sheets of floor coverings obtained in this way are horizontally spliced, the patterns of adjacent sheets will not match. thing.

Additionally, since the sheet is made of soft vinyl chloride, it has the disadvantage that black rubber scratches tend to form on the sheet surface due to friction with rubber-soled shoes.

The present invention relates to the structure of a wide and long sheet-like floor covering with an extremely excellent spine embossed pattern that eliminates all of these drawbacks.An example of its implementation is explained with reference to a drawing. A backing material 2 with poor elasticity is integrally laminated on the back side of a sheet 1 made of resin, a deep draw 3 is provided on the surface of the sheet 3, and a colored layer 4 is provided on the bottom using the valley dyeing technique (this deep draw). The technique of providing the drawing 3 and the colored layer 4 at the same time is called spine embossing), and this deep drawing 3
In addition, a pattern of shallow drawing 5 without a colored layer is arbitrarily formed (
This shallow drawing is also carried out by the usual method for spine embossing), and a transparent ultraviolet curable coating film 6 is provided over the entire surface of the sheet 1 which has been embossed with spines.

Sheet 1 is made by mixing a soft thermoplastic resin such as vinyl chloride resin in a desired manner and rolling it into a wide and long shape.
A backing material 2 is laminated on the back surface, a deep drawing 3 is provided on the surface by spine embossing, a colored layer 4 is provided on the bottom thereof, and a transparent ultraviolet curing coating film 6 is further provided on the entire surface.

The backing material 2 has poor elasticity, and under heating conditions when laminated with the sheet 1 by calender rolls or when embossing the spine, it does not cause unnecessary elongation to the sheet 1 and may shrink or cause the spine to emboss. This is to prevent pattern shift or meandering during embossing, and commonly used woven fabrics are unsuitable, so non-woven fabrics are convenient, especially synthetic fabrics such as vinylon or the like with a glass fiber layer 2' on the top surface and vinylon on the bottom surface. A non-woven fabric with a multi-layer structure of 2" of fiber waste is suitable; in this case, the top glass fiber layer 2"
A suitable material is one in which a paste such as vinyl chloride resin is applied and impregnated from the ′ side, and the paste penetrates up to 2″ of synthetic fiber waste on the back side and then heated to gel. It becomes an excellent backing material with no delamination.

After the sheet 1 made of a soft thermoplastic resin is laminated on the backing material 2 having poor elasticity in this way, the spine embossing is performed on the sheet 1.

The deep drawing 3 forms a deep concave concave on the surface of the sheet 1 on which the backing material 2 is laminated, and a colored layer 4 made of an arbitrary printing ink is provided at the bottom of the concave concave.

This deep drawing 3 and the colored layer 4 are performed simultaneously by spine embossing.

At this time, it is optional whether or not to provide a shallow draw 5 having a shallower depth than the deep draw 3, and then an ultraviolet curing coating 6 is provided over the entire surface of the sheet 1.

The ultraviolet curable coating film 6 is a coating that is well known in this type of technical field, that is, an ultraviolet curable coating, and this transparent coating is applied over the entire surface of the spine embossed sheet 1 to make the surface of the coating smooth.

This coating film 6 is provided throughout the manufacturing process, but in addition, after the sheet 1 without the coating film 6, that is, the spine embossed sheet 1 is installed at the installation site, the coating is applied to the upper surface of the sheet 1. It is also optional to apply and cure with an ultraviolet irradiation device for on-site construction.

The present invention provides deep drawing on the surface of a thermoplastic sheet having a backing material with poor elasticity, forms a colored layer at the bottom of the deep drawing, and provides a transparent ultraviolet curing coating over the entire upper surface of the sheet. This is because the backing material has poor elasticity, and when laminated with the top sheet layer in a calendar roll or heated under the heating conditions during spine embossing, shrinkage may occur because no unnecessary stretch is applied to the top sheet. No pattern shift or meandering occurs during embossing.

Moreover, in the case of a non-woven fabric with a multi-layer structure, where one side is a glass fiber layer and the other side is a non-woven fabric made of synthetic fibers such as vinylon, the non-stretchability of glass fibers is utilized to intertwine the synthetic fibers with the non-woven fabric. Since it is a laminated structure, there is no injury caused by the glass fibers even if it comes into contact with the human body, and furthermore, it has the advantage that ordinary vinyl acetate-based and acrylic-based adhesives can be used when constructing the floor covering.

Furthermore, since the surface is coated with ultraviolet curing paint to create a smooth surface, it is extremely easy to clean without clogging with mud.

In addition, the ultraviolet-cured coating film is extremely resistant to black scratches caused by the rubber sole, so the beautiful appearance of the head can be maintained forever.

Furthermore, since this ultraviolet curing coating is applied over the entire surface of the embossed spine and in such a way that the surface of the coating is flat, the embossed area of the spine and the shallowly drawn areas create an illusory depth effect. Therefore, its decorative effect is also significant.

A floor covering with such a structure can easily match patterns between adjacent ones even when horizontally splicing, and has excellent abrasion resistance and stain resistance, and is extremely easy to maintain.
