Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a construction method for applying a flooring material to a concrete floor surface.

BACKGROUND OF THE INVENTION Flooring materials such as tiles and carpets are generally applied to the floor surfaces of architectural structures such as concrete, cement mortar, ALC boards, and PC boards for aesthetic purposes and other purposes.

Traditionally, in order to install flooring on these concrete floors, the floor surface is first cleaned and an adhesive made of synthetic resin emulsion or solution such as synthetic comb, vinyl acetate, ethylene, vinyl acetate, acrylic vinyl acetate, etc. is applied. However, a method is used in which the flooring material is attached before the adhesive has dried.

However, when flooring is installed in this way, the adhesive strength of the adhesive is strong, so if the flooring is to be removed frequently for re-laying or washing the flooring, Conc IJ-1 This is inconvenient as the floor surface and flooring materials are damaged.

Also, during installation, emulsion-type adhesives have weak adhesive strength, and solution-type adhesives use organic solvents, which not only make the work environment worse, but also require that they be left as is for 1 to 2 days after installation. It has the disadvantage of peeling or shifting if not left in place.

An object of the present invention is to provide a method for constructing flooring that is easy to construct and that allows for easy removal of the flooring for replacement washing, etc., without damaging the flooring or the floor surface.

This invention is a flooring construction method characterized by applying a synthetic resin emulsion or solution to a concrete floor surface, drying it, and then pasting the flooring material on the area using an adhesive tape.

The concrete floor surface in this invention refers to the floor surface of an architectural structure represented by concrete, such as concrete, cement mortar, ALC board, PC board, etc.

Examples of synthetic resins used in this invention include 1 synthetic rubber;
Examples include vinyl acetate, ethylene vinyl acetate copolymer, acrylic, acrylic vinyl acetate copolymer, styrene, and vinyl chloride.

Adhesive tape is a tape coated with a pressure-sensitive adhesive, generally called an adhesive, on one or both sides.

The flooring materials used in this invention include vinyl chloride tiles, cushion floors, carpets, and needle novelty.

Refers to all things commonly referred to as flooring materials, such as artificial lawns and other synthetic rubber products.

Flooring construction using adhesive tape has traditionally been carried out on floors made of veneer, wood, and metal.

However, adhesive tapes are not effective on surfaces such as concrete where powder is generated due to weathering, or on surfaces where the surface layer may peel off from the main body due to adhesive force.

In the method of the present invention, a synthetic resin emulsion or solution is applied to the concrete IJ tonnage floor surface, allowed to penetrate into the interior, and dried to form a strong and smooth surface layer on the surface of the concrete floor surface. The resin layer is formed to prevent peeling of the powdered 1 surface layer due to weathering, etc., and to form a smooth surface to which the adhesive tape can be adhered.

The side of the adhesive tape that comes into contact with the floor must be coated with an adhesive; the side that comes into contact with the flooring material may be coated with either an adhesive or a general adhesive;
Adhesive tape coated with adhesive on both sides is desirable for quick work.

Since the method of the present invention is as described above, the flooring can be easily installed, the construction period can be shortened, and construction costs can be reduced.

Also, the flooring can be removed without damaging the flooring or floor surface.
Since it can be easily replaced, it is also easy to wash, and you can easily change the flooring material according to your preference and enjoy a comfortable life.

Example 1 An acrylic acid ester emulsion having a solid content of 20% was applied to a cement mortar bed made of Portland cement and sand at a rate of 60 to 70 g/rrl and dried at room temperature for 24 hours.

On the other hand, one side of the acrylic double-sided adhesive tape was attached to the carpet, and the carpet was pressed down to the floor.

The carpet did not peel or slide during daily use.

One month after installation, the corner of the carpet was pulled up with the tip of a screwdriver, and when the corner of the carpet was grasped with the hand and pulled up, the carpet was able to be removed without damaging either the carpet or the floor surface.

Example 2 In place of the synthetic resin used in Example 1, an ethylene-vinyl acetate copolymer emulsion with a solid content of 20% was used, and a floor material was applied in the same manner as in Example 1, and the same test was conducted. The results were obtained.

Comparative Example 1 A vinyl acetate solution type adhesive was applied at a coating amount of 250 to 300 g/rn' to the same floor surface as in Example 1, and before drying, a carpet was attached and left for 2 days.

Phenomena such as peeling and shearing were observed during daily use after storage.

-When I tried to remove it after a month, part of the floor came off and part of the carpet was damaged.
