[Structure] An actinic radiation curable resin pressure-sensitive adhesive layer 2 containing a monomer and / or oligomer having an unsaturated double bond is formed on the back surface of a skirting board 3 containing polyvinyl chloride and a plasticizer. A baseboard with plasticizer migration prevented.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

    The invention of the present application is based on a skirting board provided with an adhesive layer obtained by irradiating a back surface with actinic rays.     Concerned.

[Prior art]

    Conventionally, an adhesive has been used for the construction of skirting boards that are generally made of thermoplastic resin.     Have been done. However, the skirting board protects the lower part of the wall surface and is essential.     Naturally, the work of the baseboard is done at the feet, so an unnatural posture with the waist bent is necessary.     Subsequently, it was a difficult task for the construction worker.

[0003]

[Problems to be solved by the device]

    In order to solve the above problems, it is recommended to apply an adhesive to the skirting board in advance.     Was sung. However, the baseboard is usually made of vinyl chloride resin (PV     C), and the background wallpaper is PVC containing a plasticizer.     Often used, conventional pressure sensitive adhesives are affected by their plasticizers and     There was a problem that the adhesion was markedly reduced.

[0004]

[Problems to be solved by the device]

    The present invention has been made against such a background, and is a plasticizer with good workability.     The aim is to provide a baseboard with adhesive that will not be affected.

[0005]

[Means for Solving the Problems]

  According to the present invention, a monomer and / or an oligomer having an unsaturated double bond is provided on the back surface of the baseboard.   The skirting board on which the adhesive layer obtained by irradiating the rigomer with actinic light was formed.   To do.

[0006]   The actinic radiation cross-linking type adhesive in the present invention is a mono-bond having an unsaturated double bond.   Having mer and / or oligomer, and optionally tacky   A photopolymerization initiator when ultraviolet rays are used as actinic rays.   It If necessary, a solvent is included.

[0007]   The monomer and / or oligomer having an unsaturated double bond is (meth)   Butyl acrylate, 2-ethylhexyl (meth) acrylate, (meth) a   Acrylic acid, vinyl acetate, hydroxyethyl (meth) acrylate, hydr   Roxypropyl acrylate, glycidyl (meth) acrylate, N-   Methylolacrylamide and other radiations containing them as the main component   Linear crosslinkable resin. And / or monomers commonly known as   Rigomers are used.

[0008]   As a tackifier, rosin and modified rosin, terpene resin,   Petroleum resin, phenolic resin, xylene resin, liquid rubber and its modified products   Etc. can be used.

[0009]   Diethoxyacetophenone, which is generally known as a photoinitiator   Such as acetophenone series, benzene such as isopropyl benzoin ether   Zoin ether type, benzyl ketal type such as benzyl methyl ketal,   Ketones such as benzophenone can be used. In addition, amine-based   A sensitizer and the like can also be used.

[0010]   If necessary, vinyl acetate, isopropyl alcohol, methanol   A solvent such as toluene may be added.

[0011]   In the present invention, the monomer and / or oligomer is 10 to 1000 μm. It is applied to a thickness of m and is exposed to actinic light for a few seconds to a few minutes.   The adhesive used in the present invention is a cross-linkable acrylic type monomer and   And / or an oligomer is preferably used.

[0012]   FIG. 1 is a sectional view of a skirting board of the present invention, in which 1 is a skirting board main body and 2 is an adhesive layer.

[0013]   The skirting board main body 1 preferably contains 30 to 60 plasticizers per 100 parts by weight of PVC.   Although it is a soft skirting board mixed by weight, hard skirting boards and wood materials other than soft resin.   But it's okay. The thickness of the skirting board is preferably 1 to 3 mm.

[0014]   The back of the skirting board is obtained by irradiating the polymer and / or oligomer with actinic light.   Adhesive layer 2 is formed.

[0015]   FIG. 2 is a sectional view showing the construction of the skirting board of the present invention. G is floor base, 7 is floor finish   It is a source material. 1 is a baseboard body, 2 is an adhesive layer, and 4 is vinyl wallpaper. wall   The width of the present invention on a vinyl wallpaper containing PVC and a plasticizer attached to the base W   Attach the tree 3.

[0016]   In the skirting board of the present invention, an arrow is drawn at the boundary 5 between the skirting board body 1 and the adhesive layer on the back surface.   At the boundary 6 between the plasticizer A and the vinyl wallpaper 4 and the adhesive layer, the arrow A '   The migration of the plasticizer is prevented, and the baseboard 3 always has good adhesive strength.   Is maintained and there is no shrinkage.

[0017]

[Result of device]

  The baseboard was effectively attached, the construction efficiency was improved, and the burden on the operator was reduced.

[0018]   Since it is an adhesive layer obtained by irradiation with actinic rays, vinyl wallpaper and skirting book   The plasticizer from the body did not reduce the adhesive strength with time.

[0019]   The baseboard did not shrink over time.

[0020]

【Example】

  Distribute the following to the soft skirting board body containing 46 parts of plasticizer per 100 parts by weight of PVC.   UV curable adhesive resin composition is applied to a thickness of 10 μm and exposed to UV.   Shoot to get a sticky skirting board.

[0022]   On the other hand, as a comparative example, a skirting board coated with a known hot melt adhesive on the back side of the skirting board   Got The obtained baseboards of Examples and Comparative Examples were adhered to vinyl wallpaper.   The same state at 20 ° C for 3 days (A) and 50 ° C for 1 week (B).   It was kept and the adhesive strength was measured. In the baseboard of the example, no dimensional change   Although it did not occur, the baseboard of the comparative example caused shrinkage.

[0023]   The sticky skirting board of the present invention obtained above was pasted onto a vinyl wallpaper constructed on a wall base.   The initial adhesive strength can be maintained for a long period of time without any difference.   Came. On the other hand, the baseboard of the comparative example has the adhesive strength from the state A to the state B as the time passes.   The degree decreased from 1.5 kg per 2.5 cm width to 1.0 kg.
