Description

  The present invention relates to a phosphorescent carpet, and in particular, in a phosphorescent carpet in which a phosphorescent layer having a predetermined shape including a phosphorescent material is formed on a pile on the carpet surface, the phosphorescent layer is applied to the pile on the carpet surface. It can be properly formed on the top, and even when the pile color on the carpet surface is dark, the ground color of the pile is prevented from being seen through the phosphorescent layer, and the luminous performance in this phosphorescent layer is enhanced, and at night It is characterized in that it can appropriately display guidance in a dark place during a power failure or the like.

  Conventionally, decorative carpets in which letters, figures, patterns, photographs, etc. are printed with colored paints on a pile on the carpet surface are known.

  In recent years, in order to appropriately display information such as guidance in dark places at night or during a power outage, a light storage part using a light storage material is formed in a predetermined shape on the pile on the carpet surface, There has been proposed a display in which guidance or the like is displayed by the light from the phosphorescent unit.

  Here, in forming a phosphorescent portion using a phosphorescent material in a pile on the carpet surface and displaying a guide or the like, for example, as shown in Patent Documents 1 and 2, the pile on the carpet surface is displayed. On top of this, a phosphorescent paint or luminous paint is applied in a predetermined shape by printing or coating, or as shown in Patent Document 3, a phosphorescent material containing a phosphorescent material in a part of the pile on the carpet surface There has been proposed a carpet in which a synthetic fiber is used or a fluorescent sheet is interposed between a base fabric and a tip of a pile.

  However, as shown in Patent Documents 1 and 2, when a luminescent paint or luminescent paint is applied in a predetermined shape on a pile on the carpet surface by printing or coating, the luminescent paint or luminescent paint is placed between the piles. There is a problem that it becomes difficult to appropriately apply a light-emitting paint or a night paint to a predetermined shape. Further, when the color of the pile on the carpet surface is dark, there is a problem that the color of the ground of the pile can be seen through the layer of the luminescent paint or the luminescent paint, and the aesthetic appearance and display function are deteriorated. In addition, the light emitted from the light-emitting paint or night-light paint is absorbed by the pile and the light-emitting performance is greatly deteriorated, and there is a problem that guidance such as guidance in a dark place cannot be properly displayed at night or during a power failure. .

  Moreover, as shown in Patent Document 3, when using a phosphorescent fiber containing a phosphorescent material in a part of the pile on the carpet surface, such a phosphorescent fiber is manufactured separately from the normal pile fiber. Is required. Further, when such a phosphorescent fiber is used to display a predetermined shape by using a part of the carpet, the manufacture of the carpet itself is very troublesome and the display pattern can be changed. There were various problems such as difficulty and high cost of carpet production.

In addition, in the case of a carpet in which the fluorescent sheet is interposed between the base fabric and the tip of the pile as described above, the pile located on the fluorescent sheet becomes an obstacle, and sufficient display cannot be performed. The light emitted from the fluorescent sheet is absorbed by the pile, so that the light emission performance is greatly reduced, and there is a problem that guidance such as guidance in a dark place cannot be properly displayed at night or during a power failure.

  And in the luminous carpet which concerns on this embodiment, as shown in FIG.2 and FIG.3, on the pile 11 in said tile carpet 10, the white-type holding | maintenance layer 20 using a white-type adhesive is predetermined shape. (In the example shown in the figure, the shape is an arrow), and the phosphorescent layer 30 containing a phosphorescent material is formed on the white holding layer 20 in a shape corresponding to the white holding layer 20.

  Here, in forming the white-type holding layer 20 and the phosphorescent layer 30 having a predetermined shape on the pile 11 in the tile carpet 10, as shown in FIG. 4, the white-type holding layer 20 to be formed and the phosphorescent layer are formed. Using a masking member 40 provided with a hole 41 corresponding to the shape of the layer 30, a white adhesive is applied through the hole 41 on the pile 11 in the tile carpet 10, and this is cured and whitened. After forming the system holding layer 20, a phosphorescent layer coating liquid containing a phosphorescent material and a binder is applied onto the white system holding layer 20 through the hole 51 and is cured to form the phosphorescent layer 30. Can be formed.

  Thus, after providing the white type | system | group holding | maintenance layer 20 on the pile 11 of the tile carpet 10, when the phosphorescent layer 30 containing a phosphorescent material is formed on this white type | system | group holding | maintenance layer 20, the said coating liquid for phosphorescent layers will become. The tile carpet 10 is prevented from entering between the piles 11, and the phosphorescent layer 30 having a predetermined shape is appropriately formed on the pile 11 of the tile carpet 10.

  In addition, even when the color of the pile 11 on the surface of the tile carpet 10 is a dark color such as black, the white retaining layer 20 prevents the ground color of the pile 11 from being seen through the phosphorescent layer 30, so And the display function does not deteriorate.

  Furthermore, in a dark state such as at night or during a power failure, the light from the phosphorescent material in the phosphorescent layer 30 is reflected by the white retention layer 20 and is not absorbed by the dark pile 11. Irradiation is performed from the surface of the tile carpet 10, and display such as guidance in a dark place can be appropriately performed.

  Here, the type of the white adhesive used for the white holding layer 20 is not particularly limited. For example, in addition to the white modified silicone adhesive itself, a latex adhesive, a rubber hot melt, Known adhesives such as molten polymer adhesives and acrylate adhesives that contain white pigments such as titanium white, calcium carbonate, aluminum oxide, ceramic fine powder, and talc can be used. It is preferable to use a silicon-based adhesive. In addition, when including a white pigment in a well-known adhesive as mentioned above, in order to disperse | distribute a white pigment uniformly, it is preferable to use that whose particle size is 30 micrometers or less.

  In addition, as described above, the light from the phosphorescent material in the phosphorescent layer 30 is appropriately reflected by the white-type holding layer 20, and the pile 11 has a dark color such as black. In order to prevent the color of the ground from being seen through the phosphorescent layer 30, the white retention layer 20 having a whiteness specified in JIS Z8722 of 60 or more, preferably 80 or more, is used. The thickness of the white holding layer 20 is 10 μm or more, preferably 20 μm or more, more preferably 30 μm or more. However, if the thickness of the white-type holding layer 20 becomes too thick, the white-type holding layer 20 and the phosphorescent layer 30 protruding from the surface of the tile carpet 10 become so high that they can be easily spread, or the white-type holding layer 20 In addition, since the phosphorescent layer 30 is easily peeled off, the thickness of the white holding layer 20 is set to 5 mm or less, preferably 3 mm or less, more preferably 2 mm or less.

  Moreover, as a phosphorescent material used for said luminous layer 30, the well-known thing generally used can be used, It can be used repeatedly long especially, does not contain a radioactive substance, and the afterglow brightness | luminance is high. It is preferable to use one having a long afterglow time and excellent light resistance and durability. For example, calcium sulfide / bismuth (CaS / Bi), calcium sulfide / strontium / bismuth ([Ca, Sr) S / Bi), zinc sulfide / copper (ZnS / Cu), zinc sulfide / cadmium / copper [ (Zn, Cd) S / Cu] and other metal oxides such as sulfide phosphorescent materials and aluminum oxide, strontium oxide, barium oxide, calcium oxide, cerium oxide, zinc oxide, magnesium oxide, strontium oxide and the like.

In addition, two or more types having different particle diameters can be used in combination.

  In addition, when the ratio of the phosphorescent material in the phosphorescent layer 30 is small, it becomes difficult to obtain sufficient phosphorescent performance, and the afterglow luminance is reduced or the afterglow time is shortened. When the ratio is too large, the adhesive strength and strength of the phosphorescent layer 30 are reduced, so that the content is 20 to 60% by mass, preferably 30 to 45% by mass with respect to the binder.

  Moreover, if the thickness of the phosphorescent layer 30 is thin, it is difficult to obtain sufficient phosphorescent performance, and the afterglow brightness is reduced and the afterglow time is shortened, while the phosphorescent layer 30 is thick. If it becomes too much, the height of the phosphorescent layer 30 protruding from the surface of the tile carpet 10 becomes high and it becomes easy to spread or the phosphorescent layer 30 is easily peeled off, so the thickness of the phosphorescent layer 30 is 20 μm to 10 mm, preferably The range is 50 μm to 5 mm, more preferably 70 μm to 2 mm.

  Examples of the binder in the phosphorescent layer 30 include, for example, epoxy resins, urea resins, polyurethane resins, unsaturated polyester resins, acrylic resins, melamine resins, phenol resins, diallyl phthalate resins and other thermosetting resins, polyvinyl chloride, Room temperature curable synthesis such as polyvinylidene chloride, (meth) acrylic resin, styrene resin, polycarbonate, fluorine resin, acrylic silicone resin, petroleum resin, urethane modified alkyd resin, maleic acid modified rosin ester, coumarone indene resin, terpene resin Resins and mixed resins in which two or more of these are mixed, synthetic rubbers such as isoprene rubber, urethane rubber, acrylic rubber, styrene-isoprene-butylene block copolymer rubber, natural rubber, and the like can be used.
