Description

[0001]
The present invention relates to a staircase cosmetic material and a staircase .
[0002]
[Prior art]
For example, as disclosed in Japanese Utility Model Publication No. 52-29860, a slip prevention for a staircase is disclosed in which a slip-proof surface having a concavo-convex surface that is wide in the lateral direction is located on the tread portion. However, the above known anti-slip has a low design property, and there has been no disclosure of a technical idea that non-slip property increases as it approaches the nose.
[0003]
The present invention provides a staircase decorative material having a concave embossed tuning pattern synchronized with a printed pattern .
[0004]
The present invention has a kick covering portion, a tread surface covering portion, and a nose covering portion, and the kick covering portion and the tread surface covering portion have a foamed makeup with a pattern integrally formed on the surface. The above pattern is a groove-like embossed synchronized pattern formed by chemical embossing, and the groove of the tread surface covering portion is embossed deeply from the kick covering portion side toward the nose covering portion side. It is a decorative material for staircases.
Hereinafter, the present invention will be described in detail.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
“FIG. 1” is a cross-sectional view of a decorative material covering a staircase and is made of non-combustible paper, a synthetic resin sheet not containing chlorine atoms, glass fiber woven fabric or non-woven fabric substrate 1 with PVC paste or, for example, EVA, ethylene-ethyl An expandable resin such as an acrylate copolymer, (EEA), polyacrylic acid ester, polymethacrylic acid ester, and polyolefin is coated with a thickness of 0.2 to 1.0 mm from an extruder, and a fiber layer is optionally formed thereon. Laminate, preheat in a preheat oven, form a pattern on the surface of the resin layer with a transfer roll, and heat foam at 120 to 250 ° C. in the main oven. The expansion ratio is 1.3 to 20 times.
[0006]
As blowing agents, dinitrosopentamethylenetetramine, benzenesulfonyl hydrazide, p-toluenesulfonyl hydrazide, p, p'-oxybis (benzenesulfonyl hydrazide), 3,3'-disulfone hydrazide phenylsulfone, azobisisobutylnitrile, azodicarbonamide Examples of the foaming accelerator include urea ethanolamine, zinc white, lead carbonate, lead stearate, zinc stearate, glycol and the like. Furthermore, examples of the filler include aluminum hydroxide, heavy calcium carbonate, light calcium carbonate, clay, and talc.
[0007]
Benzotriazole is exemplified as the foaming inhibitor, and the content of the foaming inhibitor in the transfer pattern ink is small at the covered portion of the raised portion, and the content concentration gradually increases as it approaches the outermost edge of the tread surface. The foam inhibitor-containing ink pattern 2 is transferred to a foamable substrate, and foamed by heating to form the foamed layer 3.
[0008]
In the above production process, EVA (preferably MFR is 0.1 to 20 g / 10 min, preferably MFR is a resin not containing chlorine atoms contained in the foamable resin applied on the base material using an extruder). More preferably, the MFR is 1.0 to 10 g / 10 min, and the vinyl acetate content is 5 to 40 wt% MFR is a value indicating the fluidity of the resin, and the larger the number, the higher the fluidity. (ASTM D-1238 modified)
[0009]
When the foam layer is EVA, the foaming resin is preferably composed of a foaming agent 1 to 10 PHR, a foaming accelerator 0.1 to 5 PHR, a pigment 1 to 20 PHR, and a filler 0 to 100 PHR with respect to EVA 100 PHR. The flooring obtained in this way is useful because it does not generate toxic gas during combustion and is not inferior to the flooring using PVC in terms of strength.
[0010]
Further, the foamed resin layer is laminated in the oven immediately before heating and foaming, the film 4 is laminated, and after heating and foaming, it is decorated with chemical embossing to obtain a decorative material 8 for foaming non-slip staircase.
The decorative sheet 8 is provided with a foam layer 2, a pattern 3, and an embossed portion 5 on a base material 1.
[0011]
The chemical embossed foam includes PVC, nylon, ionomer, polyolefin,
A transparent film having a total thickness of 50 to 500 μm is laminated with the acrylic resin or the composite 1 thereof. The composite film having the above structure is not damaged by the nail, and has high scratch resistance and wear resistance.
[0012]
The entire staircase is covered with a decorative material, and the decorative sheet is provided with synchronized embossing.
The embossing depth gradually increases from the stepping side (inner side) 6 to the outer edge 7 of the tread.
In the vicinity of the outer edge of the tread surface, the chemical embossing depth is preferably 1 mm or more, particularly about 1.5 mm. The embossed pattern may be a grain, floral pattern, other geometric pattern, or abstract pattern, but is preferably a horizontally long pattern with respect to the direction of the stairs.
[0013]
In the part where the emboss is increased, a stair nose is provided on the outer edge of the staircase, and is wrapped around this. Thus, the foamed decorative material 8 of the present invention is obtained. The embossing depth may be gradually increased from the tread side (inner side) 6 to the outer edge 7 and the vicinity of the outer edge of the tread surface is chemically embossed. The depth is preferably 1 mm or more, and more preferably about 1.5 mm.
[0014]
“FIG. 2” is a non-slip step perspective view of the present invention, and the resulting staircase kick-in covering portion 10 of the cosmetic material 8 has almost no chemical embossing. In the meantime, the embossing tends to gradually become 9, 9 ′, 9 ″.
The outermost embossed decorative sheet tip 12 is wound around the nose 13. In this way, a non-slip staircase 14 is obtained. According to the present invention, the design is improved by the synchronized embossing, and the non-slip of the staircase is effectively obtained.
[0015]
In the non-slip staircase having the above-described configuration, since the emboss is gradually deepened from the kicking to the outer edge of the tread surface, it does not slip and step off the staircase. Moreover, since the pattern is chemically embossed on the foam, it is synchronized with the pattern and has excellent design. The walking feeling is also good.
[0016]
【Example】
[Example 1]
The substrate was coated with 0.5 mm of PVC foam paste and then heated pregel. Thereafter, the printed pattern was darkened so that the foaming inhibitor was closer to the outer edge, and the embossed part was transferred and printed with a horizontally long grain pattern, and then a decorative sheet foamed at 200 ° C. was obtained. As a result, a chemically embossed sheet flooring in which the pattern of 2.5 mm thickness and embossing were synchronized was obtained.
[0017]
The part of the obtained sheet that had almost no embossing was placed on the top of the kicker, and was stuck to the staircase in close contact with the kicker of the staircase and the tread surface.
A non-slip staircase having an emboss height of 1.5 mm at the outermost edge portion of the tread surface of the obtained decorative material was obtained. The staircase is highly designed and non-slip and sound-insulating.
[0018]
【The invention's effect】
1. The design of the staircase was obtained by synchronized embossing.
2. The non-slip of the stairs was obtained effectively.
