Description

  The present invention relates to a resin sheet for a table that is used by being attached to the upper surface of a table, a work table or the like.

  2. Description of the Related Art Conventionally, there is a known anti-slip mat formed by adhering an adhesive anti-slip layer made of a soft synthetic resin having self-adhesive properties to both surfaces of a base material layer made of a semi-rigid synthetic resin (Patent Document 1). reference). As a result, when sticking, there is no wrinkles or air is trapped and the appearance is not impaired, and it is assumed that it does not contain a lot of plasticizer. Without lowering the stopping effect, it is possible to reduce the decrease in the sticking and slipping preventing effect due to water wetting.

  Furthermore, as a tabletop rug that improves the ability to suppress the displacement of the table rug and prevents the rug from floating, a vacuum adsorption force or adhesive force made of a synthetic resin on one surface of a woven or non-woven sheet. The thing which formed the slip stopper which has is known (refer patent document 2). Accordingly, the slippage and floating of the tabletop laying material can be prevented, and the anti-slip layer can serve as a cushioning material to absorb the impact on the table surface by tableware and glasses.

  However, since the sticking anti-slip mat of Patent Document 1 is composed of a base material layer made of a semi-rigid synthetic resin, it does not have a sound absorbing function.

  Therefore, as one of means for imparting a sound absorbing function, it is conceivable to increase the thickness of the resin of the table resin sheet. However, in Patent Document 2, although it has an impact function, the firing magnification is set. A table lining is disclosed which increases the thickness of the anti-slip layer to increase the thickness.

  However, as described in Patent Document 2, if the coating thickness of the anti-slip layer is increased simply by increasing the firing magnification, the delamination strength decreases. That is, there has been a problem in that delamination occurs when the table laying device once attached to a table or the like is removed, and a foamed resin layer (anti-slip layer) remains on the surface of the table or the like.

  In addition, this type of table resin sheet may be rolled and distributed in the form of a roll, but if the thickness of the table resin sheet is increased, wrinkles resulting from the difference in inner diameter when wound are foamed resin layers. There was a problem that it was easy to occur and the appearance was bad.

  Therefore, it can be easily attached to the table or work table, is difficult to peel off during use, and the resin layer of the table resin layer does not remain on the table when it is intentionally removed. An object is to provide a resin sheet for a table.

  In order to solve the above problems, a resin sheet for a table according to claim 1 of the present invention is a sheet surface material formed of a synthetic resin having elasticity, a foamed resin layer having elasticity, and the sheet surface material. In addition, a colored thin film resin layer is integrally formed between the foamed resin layer, and a large number of fine suction cups are formed by exposing air bubbles to the side surface opposite to the sheet surface in the foamed resin layer. It will be.

  In the resin sheet for a table according to claim 2 of the present invention, among the bubbles mixed in the foamed resin layer, the size of a large number of bubbles mixed is set to 10 μm or less.

  In the resin sheet for a table according to claim 3 of the present invention, the thickness of the foamed resin layer is 400 μm to 1800 μm.

  According to a fourth aspect of the present invention, there is provided a resin sheet for a table according to the first, second, and third aspects of the present invention, wherein the female piece is disposed with a gap at an angle of about 90 degrees. The male part piece is formed integrally with the side piece, and the female part and the male part serving as the engaging means are formed so as to face the female part piece and the male part piece, respectively.

  Hereinafter, a resin sheet for a table according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a cross-sectional view of a table resin sheet S (sheet surface material 1, foamed resin layer 2, thin film resin layer 3) and release sheet 4 in an embodiment of the present invention. FIG. 2 is a cross-sectional view showing a state in which the release sheet 4 is scraped off from the table resin sheet S. FIG. 3 is an enlarged schematic diagram of FIG.

(Regarding the resin sheet S for the table and the release sheet 4)
The resin sheet S for table is absorbed by the upper surface of the table, work table, etc., so as to alleviate the injury and pain caused by the unexpected contact of the infant, or even if the infant's mischief or careless pulling force acts on it. Is excellent in sound absorption effect. As shown in FIG.1 and FIG.2, between the sheet | seat surface material 1 formed with the synthetic resin which has elasticity, the foamed resin layer 2 which has elasticity, the said sheet | seat surface material 1, and the said foamed resin layer 2 The thin resin layer 3 is integrally formed, and a large number of fine suction cups A are formed by exposing the bubbles 20 on the side surface of the foamed resin layer 2 opposite to the sheet surface material 1. Note that the release resin sheet 4 is detachably provided on the surface of the foam resin layer 2 where the bubbles 20 are exposed before the table resin sheet S is used. The table resin sheet S is dimensioned to, for example, 90 cm × 90 cm or 90 cm × 120 cm. Or what was wound by roll shape may be sufficient.

(Specific configurations of the resin sheet S for the table and the release sheet 4)
The sheet surface material 1 is made of a synthetic resin having elasticity, for example, a resin selected from polyester, polyvinyl chloride, polyethylene, polypropylene, nylon, urethane, acrylic, or the like, or a nonwoven fabric or a woven fabric. The thickness of the sheet | seat surface material 1 at the time of comprising from the said resin is 4-400 micrometers (preferably 30-200 micrometers), and 50-500 g / m < ² > (preferably 70-300 g in the fabric weight of a nonwoven fabric or a woven fabric). / M ² ). That is, the thickness of the sheet surface material 1 may be set so as to be easy to bend and to have strength against scratches caused by tableware or the like.

  Further, the sheet surface material 1 may be colorless, colored, or may have a pattern or the like by gravure printing or the like. Furthermore, other layers may be provided.

  The foamed resin layer 2 is obtained by mechanically mixing bubbles in a resin emulsion such as polyester, polyvinyl chloride, polyethylene, polypropylene, nylon, urethane, acrylic, etc., and applying this to the thin film resin layer 3 described in detail below and curing.・ It is formed by curing. The foamed resin layer 2 is preferably formulated by blending two kinds of acrylic resins having different degrees of polymerization and butadiene rubber (MBR). According to the above composition, the hydrolysis does not occur, so that the cohesive force becomes strong. When the table resin sheet S once adsorbed on the table or the like is removed, delamination does not occur, and the foamed resin layer 2 is formed on the surface of the table or the like. No longer remains.

  Here, the thickness of the foamed resin layer 2 is set to about 10 to 2000 μm (preferably 400 to 1800 μm). If the thickness of the foamed resin layer 2 is 400 μm or more, the sound absorption effect is excellent.

  In addition, as described above, a large number of fine suction cups A are formed on the opposite side of the foamed resin layer 2 from the sheet surface material 1 by exposing the bubbles 20 to the foamed resin layer 2. Besides, there are many cavities 21 in which air is confined. Therefore, this foamed resin layer 2 is given a certain degree of cushioning property due to air compression.

  The size of the bubbles 20 is preferably 1 μm to 100 μm, and among the bubbles 20 mixed in the foamed resin layer 2, the size of the bubbles 20 mixed in a large number is preferably 10 μm or less. preferable. By setting the size of the bubbles 20 to 10 μm or less, the cohesive force of the foamed resin layer 2 becomes strong and it becomes difficult to cause delamination. Therefore, when the table resin sheet S once adsorbed on the table or the like is removed, delamination does not easily occur, and the foamed resin layer 2 does not easily remain on the surface of the table or the like.

  Further, a colored thin film resin layer 3 is provided between the sheet surface material 1 and the foamed resin layer 2. The thin film resin layer 3 is colored by blending a pigment. The color to be colored is preferably a color that takes into consideration the color scheme of the pattern on the sheet surface material 1, for example, white so as not to impair the pattern on the sheet surface material 1.

  When the table resin sheet S is wound into a roll during distribution or the like, wrinkles resulting from an inner diameter difference due to the thickness of the table resin sheet S may occur in the foamed resin layer 2. However, by providing the thin film resin layer 3 between the sheet surface material 1 and the foamed resin layer 2, when the table resin sheet S is adsorbed on the upper surface of a table or the like, the foamed resin layer 2 from the sheet surface material 1 side. It is possible to make the wrinkles generated on the surface inconspicuous.

  As the release sheet 4, a generally known release sheet is used, and the release sheet 4 can be easily removed from the resin sheet S.

(Regarding the functions of the resin sheet S for the table and the release sheet 4)
In the table resin sheet S of this embodiment, no adhesive is used on the upper surface of the table or the like. In place of the adhesive, the foamed resin layer 2 is provided with cushioning properties, and bubbles 20 are exposed on the opposite side of the foamed resin layer 2 from the sheet surface material 1 to form a large number of micro-suckers A.

  Accordingly, when the release sheet 4 is removed and the side surface of the fine suction cup A is pressed against the table or the like, the air in the bubbles 20 is pushed out to become negative pressure, and the suction cup function of the fine suction cup A is exerted so that the resin sheet S for the table is the table. Adsorb to etc.

  Therefore, even if an infant's mischief or careless pulling force acts, it is possible to prevent the table resin sheet S from shifting. Further, since the foamed resin layer 2 is provided with cushioning properties, it has shock absorption and sound absorption. Moreover, since the resin sheet S for tables is made of resin, even if it becomes dirty, it can be easily removed by simply wiping it.

  Here, when removing the table resin sheet S from the table or the like, it is only necessary to apply a force to separate it from the table or the like. By this operation, air enters the bubbles 20 and the micro sucker A performs the sucker function. It can be easily peeled off from the wall.

  In this way, when the table resin sheet S is removed from the table or the like, adhesive marks remain at the site where the table resin sheet S has been peeled off, or the printed layer printed on the table or the like, the affixed sticker, etc. are peeled off. It is impossible to end up.

  Further, the table resin sheet S of the present embodiment has a sucker function by a large number of minute suckers A as described above. Therefore, in the table resin sheet S of the present embodiment, even if the sheet has corners or uneven portions (complex shape portions), it can be reliably adhered and may not be peeled carelessly. Absent.

  That is, in the state where the table resin sheet S is bonded to the table T, each corner of the table resin sheet S is held by the holding body 5 as shown in FIGS. Can prevent inadvertent peeling, and can alleviate injuries and pain caused by accidental contact. At this time, the resin sheet S for the table is adsorbed only on the upper surface of the table T.

  FIG. 4 is a perspective view of the holder 5 of the table resin sheet S in the embodiment of the present invention. FIG. 5 is a perspective view showing a state in which the table resin sheet S in the embodiment of the present invention is bonded to the upper surface of the table T and the corners are held by the holding body 5.

  The holding body 5 is formed by cutting the table resin sheet S into a predetermined shape. The holding body 5 is formed by integrally forming a female piece 51 and a male piece 52 with a side piece 53 arranged with a gap at an angle of approximately 90 degrees. For example, the female piece 51 and the male piece 52 are formed in a substantially fan shape. Further, the side piece 53 is formed in a substantially square shape.

  The female part 51 and the male part 52 are provided with a female part 54 and a male part 55 which are engaging means so as to face each side having the gap. The boundary between the female piece 51, the male piece 52 and the side piece 53 is a folding line 56 extending in the horizontal direction. Further, a line that hangs down from the intersection of the female piece 51 and the male piece 52 toward the side piece 53 and bisects the width direction of the side piece 53 is a folding line 57 extending in the vertical direction.

  The holding body 5 is attached to a corner of the table T in a state where the table resin sheet S is bonded to the upper surface of the table T. Specifically, the corners of the resin sheet S for table S are covered with the female part 51 and the male part 52, and the female part 54 and the male part 55 are connected with the folding lines 56 and 57 bent. Engage and adsorb to the corners of the resin sheet S for table and the table T. As a result, the female piece 51 and the male piece 52 are attracted to the corners of the table resin sheet S, and the side pieces 53 are attracted to the side surface of the table T. Accordingly, inadvertent peeling from each corner of the resin sheet S for the table can be prevented, and the corner of the table T can be covered with the holding body 5, so that the unexpected contact at the corner of the table T can be prevented. Can alleviate injuries and pain. The holding body 5 can also be directly attached to the corner of the table T.
