[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION In the present invention, a pressure-sensitive adhesive layer obtained by irradiating actinic rays on the back surface of a baseboard having no adhesive or pressure-sensitive treatment (hereinafter referred to as the baseboard body) is provided. About baseboard.

[0003]

[Problems to be Solved by the Invention] In order to solve the above problems, it has been proposed to apply an adhesive to the baseboard in advance. However, the baseboard body is usually made of a vinyl chloride resin (PVC) containing a plasticizer, and the base wallpaper is often made of PVC containing a plasticizer. Under the influence of these plasticizers, there is a problem that the adhesive strength is significantly reduced.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such a background, and has as its object to provide a baseboard with an adhesive which has good workability and is not affected by a plasticizer or the like. .

[0005]

Means for Solving the Problems The present invention relates to a skirting board having a pressure-sensitive adhesive layer formed by irradiating a monomer and / or oligomer having an unsaturated double bond with actinic light on the back surface of the baseboard body. Things.

The actinic ray-crosslinkable pressure-sensitive adhesive in the present invention is:
It has a monomer and / or oligomer having an unsaturated double bond and, if necessary, contains a tackifier and, if ultraviolet rays are used as actinic rays, a photopolymerization initiator. Further, if necessary, a solvent is included.

The monomers and / or oligomers having an unsaturated double bond include butyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, (meth) acrylic acid, vinyl acetate, hydroxyethyl (meth) acrylate, and hydroxyethyl (meth) acrylate. Propyl acrylate, glycidyl (meth) acrylate, N-methylolacrylamide, and other radiation-crosslinkable resins containing these as a main component.
Monomers and / or oligomers commonly known as are used.

As the tackifier, rosin and modified rosin, terpene resins, petroleum resins, phenolic resins, xylene resins, liquid rubbers and modified products thereof can be used.

As the photoinitiator, generally known acetophenones such as diethoxyacetophenone, benzoin ethers such as isopropylbenzoin ether, benzyl ketals such as benzyl methyl ketal, and ketones such as benzophenone are known. Can be used. Further, amine sensitizers and the like can be used.

Further, if necessary, a solvent such as vinyl acetate, isopropyl alcohol and methanol / toluene may be added.

In the present invention, the monomer and / or oligomer is applied to a thickness of 10 to 1000 μm and irradiated with actinic light for several seconds to several minutes. The pressure-sensitive adhesive in the present invention is preferably obtained by using a crosslinkable acrylic type monomer and / or oligomer.

FIG. 1 is a cross-sectional view of the baseboard of the present invention, wherein 1 is a baseboard body and 2 is an adhesive layer.

The baseboard body 1 is preferably a soft baseboard containing 30 to 60 parts by weight of a plasticizer with respect to 100 parts by weight of PVC, but may be a hard baseboard or a wood material other than the soft resin.
The thickness of the baseboard is preferably 1 to 3 mm.

An adhesive layer 2 obtained by irradiating the polymer and / or oligomer with actinic light is formed on the back surface of the baseboard body.

FIG. 2 is a sectional view of the construction of the baseboard according to the present invention. G is a floor substrate, and 7 is a floor finishing material. 1 is a baseboard body, 2 is an adhesive layer, and 4 is a vinyl wallpaper. The present invention baseboard 3 is attached to a vinyl wallpaper containing a PVC and a plasticizer attached to the wall substrate W.

In the baseboard of the present invention, a plasticizer indicated by an arrow A at a boundary 5 between the baseboard body 1 and the adhesive layer on the back surface, and a plasticizer indicated by an arrow A 'at a boundary 6 between the vinyl wallpaper 4 and the adhesive layer. Migration is prevented, and the baseboard 3 always maintains good adhesive strength and does not shrink.

[0017]

[Results of the Invention] The baseboard was effectively attached, the construction efficiency was improved, and the burden on the workers was reduced.

Since the pressure-sensitive adhesive layer was obtained by irradiation with actinic light, the adhesive strength did not decrease over time due to the plasticizer from the vinyl wallpaper or the baseboard body.

The baseboard did not shrink over time.

EXAMPLES A UV curable adhesive resin composition having the following composition was applied to a soft baseboard containing 46 parts of a plasticizer with respect to 100 parts by weight of PVC to a thickness of 10 μm, and irradiated with UV to obtain an adhesive baseboard. Was.

On the other hand, as a comparative example, a baseboard having a known hot-melt adhesive applied to the back of the baseboard body was obtained. The obtained baseboards of Examples and Comparative Examples were adhered to vinyl wallpaper at 20 ° C. for 3 days (A) and at 50 ° C. for 1 week (B).
The adhesive strength was measured while maintaining the same condition. The skirting board of the example did not undergo any dimensional change, while the skirting board of the comparative example shrunk.

The obtained adhesive baseboard of the present invention was able to maintain its initial adhesive strength for a long period of time without any difference even if it was stuck on a vinyl wallpaper applied on the wall base. On the other hand, the adhesive strength of the skirting board of the comparative example decreased from the state of A to the state of B with time, from 1.5 kg to 1.0 kg per 2.5 cm width.
