  Patent Document 1 describes a configuration in which an elastic sheet made of a rubber chip material is provided on a rubbery base sheet to form a temporary road marking sheet. However, a rubbery sheet slips when wet with water. The problem that it becomes easy is considered.

  Therefore, the present invention provides a road marking sheet that is difficult to slip even when wet with rainwater or the like.

In order to achieve the above object, the present invention is configured as follows.
That is, the road marking sheet according to the present invention is a road marking sheet used on the road surface,
A base material having flexibility, and a sign sheet provided on the upper surface of the base material to draw a road sign,
The marking sheet is obtained by melting a sheet composition in which a binder, in which an ethylene-vinyl acetate copolymer and rosin are blended, with a wax, and an additive including at least a coloring material and a reflective material, is melted. It is characterized by being formed into a shape.

The road marking sheet according to the present invention includes a flexible base material, and a marking sheet provided on the upper surface of the base material to draw a road marking. The marking sheet is made of ethylene-vinyl acetate copolymer. The sign sheet is wetted because the sheet composition in which the binder and the rosin are blended with the wax and the additive containing at least the coloring material and the reflective material are melted and formed into a sheet shape. Further, the tire of the vehicle that has a high slip resistance value and passes above is made difficult to slip.
Moreover, since a reflective material is included, the visibility from the vehicle etc. which is lighting a headlight etc. is made favorable.
In addition, since a sign sheet is provided by adding an additive containing a wax and a reflecting material to a binding material in which an ethylene-vinyl acetate copolymer and rosin are blended, the reflecting material is firmly attached to the marking sheet by the binding material. It is fixed, the drop-off of the reflective material from the marking sheet in the process of using the road marking sheet is suppressed, and good visibility can be continuously obtained.

  Further, if the sign sheet is formed so that a plurality of display areas are combined in a planar shape to draw a three-dimensional figure, and the shadow of the three-dimensional figure is expressed by a difference in brightness in each display area Since the sign on the sign sheet is visually recognized as a three-dimensionally raised road sign and the driver of the vehicle is decelerated intuitively, it should be used well as a road sign sheet that prompts the traveling vehicle to decelerate. Is preferable.

In addition, if a plurality of the marking sheets are formed and each marking sheet is provided so as to constitute the plurality of display areas, the road marking of the three-dimensional figure can be easily formed on the base material. ,preferable.
In addition, each of the marking sheets is provided on the base material so that there is no vertical overlap between the marking sheets arranged adjacent to each other, and each of the marking sheets is formed by each of the marking sheets. If it is provided so as to constitute at least a part of the outer peripheral edge of the figure, the base material is deformed so that each of the indicating sheets moves in the direction of the outer peripheral edge to reduce the load on each indicating sheet, This is preferable because damage such as cracking and tearing of the sheet is suppressed.

  According to the road marking sheet of the present invention, it is difficult to slip even when it gets wet with rainwater or the like.

It is a figure which shows the state which decomposed | disassembled the road marking sheet | seat of FIG. 1 into each member. It is sectional drawing which shows an example of a deformation | transformation state when force is applied to the road marking sheet | seat of FIG. It is a top view which shows another form of implementation of the road marking sheet which concerns on this invention.

It is a top view which shows another form of implementation of the road marking sheet which concerns on this invention. It is a figure which shows the state which decomposed | disassembled the road marking sheet | seat of FIG. 7 into each member.

Embodiments of the present invention will be specifically described with reference to the drawings.
The road marking sheet of the present embodiment is provided so as to draw a three-dimensional figure by combining three display areas a, b, and c in a planar shape. The display areas a to c are provided in different colors so that the brightness is different, and are arranged in a positional relationship in which the brightness difference between adjacent display areas can be expressed as a shade.
Here, the positional relationship in which the brightness difference between adjacent display areas can be expressed as a shading is that the three-dimensional figure originally represents a three-dimensional plane by an equiangular drawing method, an inclined drawing method, etc. If the display areas a to c are the same in brightness but different in hue, they are not visually recognized as a solid if they are consciously viewed, but in order to be more easily viewed as a solid, a light beam is just a virtual solid consisting of the solid figure. This means a positional relationship in which the lightness difference between the display areas a to c of the three-dimensional figure is expressed as a shadow as if the shadow is generated by irradiation from one direction.

In the road marking sheet of FIG. 1, the display area b constituting the left slope portion is formed in white (lightness by Munsell is about 9), and the display area c constituting the front portion is yellow (lightness by Munsell is about 7). A triangular solid figure is formed by forming the display area a forming the right slope portion in blue (lightness by Munsell is about 5). Accordingly, the brightness of each of the display areas a to c is the highest in white and decreases in the order of yellow and blue, so that the left slope portion of the display area b is highest, and the front portion and the right slope portion are darker in this order. As a result, the light beam is irradiated from the upper left front of the virtual solid that rises in a triangular shape, and appears to be darker in the order of the front portion and the right slope portion.
Further, the brightness difference of each display region is preferably about 2 or more in Munsell value as in this embodiment, and as a result, the brightness difference becomes less visible as the brightness difference becomes smaller.

  In this way, a plurality of display areas with different brightness are formed, arranged so as to represent a three-dimensional figure in a plane, and the brightness difference between adjacent display areas can be expressed as a shadow. The arranged road marking is a display in which each display area is arranged in a planar shape, but is a solid figure having a shadow, so that it is visually recognized as a three-dimensionally raised road sign, and visibility is improved.

It is a figure which shows the state decomposed | disassembled into each member.
1 is a base material.
The base material 1 is formed in a flexible sheet shape or plate shape, and has flexibility enough to deform to follow the surface irregularities to some extent when placed on the road surface G.
Specifically, the base material 1 of the present embodiment is formed of an elastic material, and even if the vehicle is deformed by the force applied from the upper surface, such as when a vehicle or the like steps on the road marking sheet, the original material is subsequently restored. It is formed to restore its shape. As the material of the base material 1, a synthetic resin such as an elastomer or an elastic material such as rubber can be suitably used, and the base material 1 of the present embodiment is formed using chloroprene rubber.
Further, the thickness of the base material 1 is preferably about 2 mm to 10 mm. When the thickness is less than 2 mm, it is easily damaged when stepped on the vehicle. When the thickness exceeds 10 mm, The impact becomes large and problems such as misalignment from the installation location tend to occur.
The base material 1 of this embodiment is formed in a vertically long pentagon, and the shape thereof is formed to be the same as the external shape of the three-dimensional figure.

Reference numerals 3a, 3b and 3c are marking sheets.
The marking sheets 3 a to 3 c are individually formed into flexible sheet shapes, are arranged so as to constitute the display areas a to c, and are fixed to the upper surface of the substrate 1.
The marking sheets 3 a to 3 c include sheet pieces 31 a to 31 c and a pressure-sensitive adhesive layer 32 provided on the back surface thereof, and are attached and fixed to the upper surface of the substrate 1 to which the primer 2 is applied.

Each of the sheet pieces 31a to 31c is formed of a sheet composition, and this sheet composition is a binder that contains an ethylene-vinyl acetate copolymer (hereinafter referred to as EVA) and rosin, wax, and coloring. It is formed by blending materials such as materials, fillers, and reflective materials. The sheet pieces 31a to 31c are formed by heating and melting the above sheet composition and uniformly mixing the sheet composition.
In addition, the sheet pieces 31a to 31c are formed such that the respective display areas a to c can be configured by adding different colorants to the additive and changing the color tone.

  EVA is used to impart flexibility, impact resistance, and durability to each of the sheet pieces 31a to 31c. However, when the vinyl acetate content in EVA is less than 15% by weight, the flexibility decreases. When the amount exceeds 40% by weight, the heat resistance and wear resistance deteriorate, so the vinyl acetate content is preferably within the range of 15% by weight to 40% by weight.

  As rosin, in addition to natural rosin and terpene resin, synthetic rosin-like compounds such as petroleum resin, coumarone resin, xylene formalin resin, indene resin and the like can be used in the same manner. Those esterified with glycols and the like, and those modified with formaldehyde, amines or unsaturated acids such as maleic acid can also be preferably used. These rosins are not limited to one type and may be used in combination of two or more types. Note that rosin-modified maleic acid resin and terpene resin obtained by adding maleic acid and esterifying simultaneously with rosin esterification with polyhydric alcohol are compatible with EVA compared to other rosins. It is preferable because weather resistance and heat resistance are good and the road marking sheet using the sheet pieces 31a to 31c is not embrittled or discolored when used on the road surface.

Explaining the composition of the sheet composition of each of the sheet pieces 31a to 31c of the present embodiment, 240 parts by weight of EVA having a vinyl acetate content of 28% by weight as a binder and 100 parts by weight of natural rosin are blended, and polyethylene wax as the wax 11 parts by weight and 6 parts by weight of ethylenebisstearic acid amide, 110 parts by weight of calcium carbonate having a small particle size as an additive, 330 parts by weight of calcium carbonate having a large particle size, and glass beads that function as a reflective material having retroreflectivity 160 parts by weight and 43.4 parts by weight of a coloring material were blended, and 100 parts by weight of the base material composition was prepared by blending all of the binder, wax, and additive.
Each of the sheet pieces 31a to 31c is formed by heating and melting the sheet composition at 130 to 180 ° C., uniformly mixing the sheet composition, forming the sheet composition, and cooling and solidifying the sheet composition.
The above-mentioned calcium carbonate having a small particle size is calcium carbonate whose particle size is adjusted so that 95% by weight or more passes through a standard sieve of 325 mesh, and the calcium carbonate having a large particle size is a standard having 95% by weight or more of 28 mesh. Calcium carbonate that has been adjusted in particle size to pass through a sieve and remain on an 80 mesh standard sieve. (Hereinafter, each sheet piece formed using the sheet composition having the above-mentioned composition is referred to as Example 1)

Each sheet piece 31a to 31c of the present embodiment is provided with good flexibility by containing EVA in the sheet composition, and when the road marking sheet of the present invention is placed on the road surface When the base material 1 follows the road surface unevenness and bends and deforms, the sheet pieces 31a to 31c are hardly cracked or broken. Further, when the road marking sheet is collected from the road surface, even when the road marking sheet is wound up, cracks and breaks are less likely to occur.
Each of the sheet pieces 31a to 31c is less flexible when the content of EVA in the sheet composition is less than 20% by weight, and the possibility of breakage and the like is increased. Therefore, the EVA content in the sheet composition is 20% by weight. % Or more, and more preferably 24% by weight or more.
Further, if the EVA content in the sheet composition exceeds 40% by weight, the stickiness of each of the sheet pieces 31a to 31c increases, and the risk of adhesion of dirt to the surface increases. And is more preferably 30% by weight or less.

The pressure-sensitive adhesive layer 32 provided on each of the marking sheets 3a to 3c of the present embodiment is a layer formed by attaching a pressure-sensitive pressure-sensitive adhesive.
Each of the marking sheets 3a to 3c of the present embodiment is bonded to the upper surface of the base material 1 to which a synthetic rubber-based or urethane-based primer 2 has been applied in advance, and then pressed and pressed from above and below by a roller press or the like. A road marking sheet is formed.
The material of the pressure-sensitive adhesive used for forming the adhesive layer 32 is not limited as long as the sheet pieces 31a to 31c can be pressure-bonded and fixed to the substrate 1. For example, a known adhesive such as an acrylic copolymer resin or a rubber adhesive is used. In this embodiment, the adhesive layer 32 is formed using a rubber-based adhesive.
Moreover, the pressure-bonding method of the marking sheets 3a to 3c is not limited to the roller press, and may be crimped by hitting the marking sheets 3a to 3c attached to the upper surface of the substrate 1 with a hammer or the like. The method may be used.

Each marking sheet 3a to 3c of the present embodiment is arranged so as to constitute each display region a to c constituting the three-dimensional shape and is crimped and fixed to the base material 1, but as shown in FIG. In the inner edge X where the edges are in contact with adjacent sign sheets, the sign sheets 3a to 3c are arranged so as to abut each other without overlapping in the vertical direction.
By providing the inner edge X in this way, when the base material 1 is deformed, for example, when a vehicle or the like steps on the road marking sheet placed on the road surface, the edge of each marking sheet disposed adjacent to the inner edge X Are separated and can move following the deformation of the base material 1, so that the load on each marking sheet is reduced and the damage of the marking sheets 3 a to 3 c due to the deformation of the base material 1 can be suppressed.
4 is a cross-sectional view showing an example of a deformed state when a force is applied to the road marking sheet of FIG.

  In addition, the marking sheets 3a to 3c of the present embodiment are respectively formed and arranged so as to constitute at least a part of the outer peripheral edge of the three-dimensional figure formed by the marking sheets 3a to 3c. When a vehicle or the like steps on the road marking sheet placed on the road surface, the base material 1 is often deformed outwardly so as to be crushed. However, the marking sheets 3a to 3c are provided as described above. Thus, since each of the marking sheets 3a to 3c can follow the deformation of the base material 1 so as to move in the direction of the outer peripheral edge F, the load on each of the marking sheets 3a to 3c is reduced. Damage to each of the marking sheets 3a to 3c accompanying the deformation can be suppressed.

  The road marking sheet of the present embodiment is provided so as to configure the display areas a to c of three-dimensional figures having different brightness in three stages by the marking sheets 3 a to 3 c, but is not limited thereto. You may provide so that a display area | region from which lightness differs in 2 steps | paragraphs may be provided, and you may provide so that a display area in which lightness differs in 4 steps | paragraphs or more.

The result of having measured the slip resistance value in the wet state between the embodiment of the sheet piece and the substrate 1 formed of sheet-shaped chloroprene rubber will be described.
The sample of Example 1 of the sheet piece is formed by molding the sheet composition having the above composition into a sheet shape by the above method.
The sample of the sheet piece of Example 2 is different from Example 1 only in that glass beads are not mixed into the sheet composition having the above composition.
In the sample of Comparative Example 1, chloroprene rubber, which is a material of the base material 1, is formed into a sheet shape.

  The slip resistance value in a wet state was determined by attaching each of the prepared samples on a flat test bench and leaving the upper surface in a wet state, then a portable skid tester (developed by the UK Road Traffic Research Institute. WF Stanley) The sliding resistance value (BPN value) was measured using

As a result of measuring the slip resistance value of each sample, the measured values of 47 BPN in Example 1, 28 BPN in Example 2, and 23 BPN in Comparative Example 1 were obtained.
By arranging and forming the sheet pieces 31a to 31c on the upper surface of the road marking sheet, it is possible to provide the wet-like body with less slippage than when using the rubber.
Further, as in Example 2, even if each sheet piece is formed without containing glass beads in the sheet composition, it can be provided with less slippage in the wet state than when formed using rubber.
In addition, by mixing glass beads in the sheet composition, the slip resistance in a wet state can be improved, and the sheet piece can be provided with retroreflectivity that reflects the irradiated light toward the light source. It is preferable because the visibility of the road marking sheet at night as well as during the day can be improved.
In addition, by forming each marking sheet with each sheet piece formed from the sheet composition, the sheet composition can be melted at a temperature of about 130 to 170 ° C. and formed into a sheet shape. It is preferable because a sheet piece having a desired color tone can be easily formed by adjusting the composition of additives such as glass beads.
