Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to road marking materials such as road center lines, pedestrian crossings, and indication lines.

Conventional road marking materials of this type include melting type, hot paint type-1 (cold) paint type, sheet pasting type, chain type,
There are methods such as the embedding method, which are actually used, but the melting method and hot painting method are the most popular.

This is because it has the visibility, slip resistance, and appropriate durability required for road marking materials.

At present, other methods are also being used that take advantage of their respective characteristics.

However, the melting and hot painting methods require a construction vehicle and a large amount of paint, making it very difficult to work in narrow spaces, and at the same time, they are dangerous because they use fire. Therefore, workers must be extremely careful when working.

The (cold) paint method is suitable for local marking because it uses rollers, brushes, etc., but the amount of work required is not comparable to that of the melt method.

In addition, it takes time for the paint to dry, and it is difficult to expect vehicles to pass through the area immediately.

In the sheet type, the sheet is placed at the construction site and heated, and a layer of adhesive material is attached to the back of the sheet.

However, the former method is attached using a burner, etc., so the work is as dangerous as the melting method, and the latter method is attached using an adhesive, so the work is easier and less dangerous. Although the visibility and other properties are equivalent to the meltability, the cost is currently high.

As for tin, crosswalks with protrusions are dangerous and cause loud noise due to vehicle vibrations, and recessed crosswalks are sometimes used as a measure against spikes, tires, and chains in snowy areas. However, the cost is very high and the effects are not that great.

In addition, if the above-mentioned marking materials (melt type, painted type, sheet type, etc.) are flat after installation, their reflectivity decreases not only during snowfall but also when the road surface is wet, making it difficult for cars etc. The disadvantage was that it was very difficult for the driver to see.

The present invention has been made in view of the above circumstances, and has low vibration to automobiles, etc., good reflectivity even at night and in rainy weather, and good reflectivity even after long-term use and wear. In addition, it was made with the aim of obtaining a road marking material that is easy to attach to roads, and a portion of the glass beads is exposed from the surface of a sheet base material mixed with glass beads,
It is characterized in that a pressure-sensitive adhesive layer is laminated on the back side of the sheet base material, and the surface of the sheet base material has a corrugated cross section.

Hereinafter, the present invention will be explained in section L) based on an embodiment shown in the drawings.

Fig. 1 is a perspective view of a road marking material according to an embodiment of the present invention, Fig. 2 is a side view of Fig. 1, and Fig. 3 is a partial enlarged view schematically showing a cough example. FIG. 4 is an explanatory diagram of glass beads reflecting light from headlights of an automobile or the like.

(1) is a road marking material, Sea 1-base material (2'),
It is formed by sequentially laminating a special adhesive layer (3) and a separator (4).

The sheet base material (2) is made by uniformly mixing thermoplastic elastomer, petroleum-based synthetic resin, coloring pigment, filler such as calcium carbonate, and glass beads (5) by heating at high temperature. As shown in Figure 2, it has a wavy portion (6) with a corrugated cross section on its surface.

The above-mentioned wavy portion (6) is formed smoothly and conforms to the shape of the tires of automobiles, etc., so that vibrations generated when automobiles, etc. pass will have little effect on the driver and are safe. It is formed.

That is, in the case of this embodiment, as shown in FIG.
Distance from one valley of road marking material (1) to the next valley II (L)
and the distance (M) from one mountain to the next mountain is approximately 4.
The thickness of the road marking material (1) at its thinnest part (S) is about 1.5 + a + s, and the thickness at its thickest part (T) is about 3 cm.

The width (W) of the road marking material (1) is approximately 15 cm.

Thus, the wavy portion (6) allows rainwater to flow into the concave valley portion during or after rainy weather, and can effectively remove rainwater from the raised mountain portion.

Moreover, as shown in FIG. 3, on the surface of the sheet base material (2), there are glass beads (5) mixed in the sheet base material (2).
A part of it is exposed.

The special adhesive layer (3) is made of an adhesive that can be attached to conventionally used asphalt roads and concrete roads, and is laminated on the back surface of the sheet base material (2).

The separator (4) is made by coating the surface of a release mount made of paper or the like with silicone, etc., and is the opposite side of the special adhesive layer (3) from the side that comes into contact with the sheet base material (2). On the other side (this is being temporarily worn.

Hereinafter, the actual method of using the road marking material (1) according to the present invention will be explained.

First, while peeling off the separator (4) of the road marking material (1), the sheet base material (2) with the special adhesive N (3) on the back is pasted onto the road surface from one end.

In this case, the sheet base material (2) is started to be pasted in consideration of the position to be pasted in advance.

Further, in this case, the sheet base material (2) is pasted without being pulled.

- Once the sheet base material (2) of the piece of road marking material (1) has been pasted, press the surface of the sheet base material (2) with a heavy roller or the like to prevent it from sticking to the road. becomes better.

The sheet base material (2) of the road marking material (1) has a corrugated cross-sectional shape, and a portion of the glass beads (5) are exposed on its surface, so that vibrations to automobiles, etc. are reduced. , and the glass beads (5), as shown in FIG.
The exposed portion of the sheet base material (2) reflects light from car headlights, etc. to clearly display the road marking material (1).
In addition, during or after rainy weather, rainwater, etc. flows into the concave portions of the corrugations of the road marking material (1) and rainwater from the raised portions of the corrugations is effectively removed. The raised parts of the sheet reflect light from car headlights, etc. to improve visibility on rainy days, and the reflectivity is good even at night. Even if the glass beads (5) exposed from the base material (2) come off, the sheet base material (
Other glass beads (5) mixed in 2) are exposed, and the glass beads (5) reflect light from car headlights, etc., and clearly display the road marking material (1). It is possible to obtain a road marking material (1) that has good reflectivity even when worn.

Moreover, a special adhesive layer (3) is provided on the back side of the sheet base material (2).
) is laminated, making it easy to attach to roads.

The present invention is not limited to the above embodiments, and for example, the sheet base material (2) and the separator (4) may be made of different materials.

Since the present invention is configured as described above, it causes less vibration to automobiles, etc., has good reflectivity even at night or on rainy days, has good reflectivity even when used for a long period of time, and can be attached to roads. It is possible to obtain road marking materials that are easy to use.
