Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flooring material, and more particularly to a flooring material suitable for laid floor construction and a method for producing the same.

[0002]

2. Description of the Related Art In a condominium or the like, for example, floors made of wood or resin are placed side by side on a slab, and they are fixed by an adhesive to form a floor. However, it is very troublesome and time-consuming to apply and harden the adhesive to apply the floor material using the adhesive as described above, which is a great problem in terms of construction and cost. was there.

Therefore, recently, a floor material is positioned and juxtaposed on a slab without using an adhesive.
The floor is constructed by laying floor materials.

[0004]

However, in the case of constructing a floor by laying down as described above, if a wooden floor material is used, the floor material lacks flexibility if the slab surface is uneven. At that position, the floor material floated up, and because the floor material surface was sparse and the adhesion to the slab surface was poor, the floor material was misaligned with use.

On the other hand, when a thin floor material made of synthetic resin is used, the above-mentioned problems are small, but there is a basic problem that it is light and easy to lift because of its small weight. Therefore, it is conceivable to increase the weight by increasing the size of the floor material made of synthetic resin, but in that case, the manufacturing cost increases, and if the thickness increases, the flexibility is impaired and the above wooden The same problem as flooring will occur.

As described above, at present, no floor material suitable for being laid is provided. The present invention has been made in view of the above circumstances, and an object thereof is to provide a flooring material suitable for being laid.

[0007]

In the invention according to claim 1 of the present invention, a floor material is attached to a surface decorative body and a back surface of the surface decorative body, each of which is provided through a space having a predetermined width, and , A plurality of wood materials located at the same height, and a synthetic resin layer attached so as to leave the space on the entire exposed surface of each of the wood materials.

The constitution is such that 0.1 to 10.0 parts by weight of a polyamine compound is added.

The vinyl chloride-based polymer for paste processing used in the above is a vinyl chloride homopolymer and / or a vinyl chloride copolymer, and common ones can be used. As the polymer, one kind of polymer or a mixture of two or more kinds of polymers can be used.

The vinyl chloride copolymer refers to a copolymer with a vinyl compound copolymerizable with vinyl chloride, and is not particularly limited, but as the vinyl compound copolymerizable with vinyl chloride, for example, acetic acid is used. Vinyl esters such as vinyl, vinyl propionate, vinyl myristate, vinyl oleate and vinyl benzoate; unsaturated carboxylic acids such as acrylic acid, methacrylic acid, maleic acid, fumaric acid and cinnamic acid or anhydrides; acrylic acid Acrylic esters such as methyl, ethyl acrylate, butyl acrylate, octyl acrylate, benzyl acrylate, glycidyl acrylate, hydroxyethyl acrylate, hydroxypropyl acrylate; methyl methacrylate, ethyl methacrylate, butyl methacrylate, Octyl methacrylate,

Examples of the vinyl chloride-based polymer for paste processing used in the above may include one or two or more of these vinyl compounds copolymerized with vinyl chloride.

It is preferable to use a vinyl chloride copolymer because of its excellent workability at low temperature and in a short time,
A vinyl chloride-vinyl acetate copolymer is particularly preferable. Further, the vinyl chloride-vinyl acetate copolymer copolymer composition at that time has a vinyl acetate content of 1 because the vinyl chloride plastisol composition obtained is excellent in adhesiveness and storage stability when processed at low temperature for a short time. It is preferably ˜20 wt%, and particularly preferably 3 to 10 wt%.

As the degree of polymerization of the vinyl chloride-based polymer for processing paste, a general one having a polymerization degree of 500 to 5000 can be used, and in particular, it is excellent in processability at a low temperature and a short time.
800-2OO due to high adhesion and coating strength
O is preferred.

The plasticizer used in the above is
Any one can be used as long as it can uniformly disperse the vinyl chloride polymer for paste processing, for example, di-n-octyl phthalate, di-2-
Examples include ethylhexyl phthalate, dibutyl phthalate, diisononyl phthalate, butylbenzyl phthalate, dilauryl phthalate, dihexyl phthalate, diheptyl phthalate, diisodecyl phthalate, dioctyl adipate, tricresyl phosphate, other polyesters, and tetrahydrophthalate. These plasticizers can be used alone or as a mixture of two or more.

Further, in the above-mentioned constitution, for the purpose of further improving the strength of the processed film, a reactive type plasticizer represented by diallyl phthalate or the like can be used alone or in combination with other ordinary plasticizers. .

The blending amount of the plasticizer in the above-mentioned constitution imparts processing stability, and there is little risk of bleeding out of the plasticizer from the resulting vinyl chloride plastisol composition. United l0
30 to 250 parts by weight is preferable with respect to 0 parts by weight, and particularly 30 to 90 parts by weight is preferable because the vinyl chloride plastisol composition obtained has excellent adhesiveness and film strength.

In the above-mentioned constitution, by adding the polyamine compound to the vinyl chloride plastisol for paste processing, the polyamine compound is uniformly dispersed in the sol, so that the adhesion to the wood material is improved with a small addition amount. In addition, it is possible to obtain a vinyl chloride plastisol composition having excellent storage stability.

As the polyamine compound used in the above, a polyamine compound having a molecular weight of 500 to 20,000 and an amine value of 10 mg equivalent / g-solid or more is used. If the molecular weight of the polyamine compound is less than 500 or exceeds 20,000, the anchoring effect, which is indispensable for the adhesive effect to the wood material, is difficult to develop, and the adhesiveness cannot be expected to be improved, which is not preferable. Further, in the case of a polyamine compound having an amine value of less than 10 mg equivalent / g-solid, a sufficient adhesive effect cannot be obtained because the number of active groups involved in adhesion to the wood material is small, which is not preferable. The polyamine compound has a molecular weight of 500.

When the blending amount is less than 0.1 parts by weight with respect to 100 parts by weight of the vinyl chloride polymer for paste processing, a sufficient adhesive effect to a wood material cannot be obtained, and the vinyl chloride polymer for paste processing is not obtained. When the blending amount exceeds 10 parts by weight with respect to 100 parts by weight, further improvement of the adhesive effect to the wood material depending on the blending amount cannot be expected, and the manufacturing cost of the processed coating increases, or However, it is not preferable because it has a problem that the viscosity tends to increase during storage and storage stability becomes poor. Then, since a vinyl chloride plastisol composition for adhering wood materials having excellent adhesiveness is obtained efficiently, the amount of the polyamine compound is 0.5 to 5 parts by weight with respect to 100 parts by weight of the vinyl chloride polymer for paste processing.
