Description

Description: TECHNICAL FIELD The present invention relates to a method for treating a surface such as a pavement.

[Prior art] The pavement or the like referred to here is not only a general pavement but also a road or other ground having a smooth surface to some extent, for example, a garden,
It is used as a concept that includes parks, courtyards inside buildings, and even buildings.

Since pavements, especially sidewalks having roofs and arcades, are used as shopping streets and courtyards, their aesthetics are important. For this reason, various surface treatments are performed in addition to the pavement like a normal road.

For example, a tiling method in which tiles are laid in a mosaic form, a stone bonding method in which a natural stone plate is laid, or a plate made of a synthetic resin is laid.

[Problems to be Solved by the Invention] However, the method of laying tiles and stones requires bonding one by one on site, which is a very laborious operation.

In addition, there is also a disadvantage that the construction period is not constant due to the weather and the temperature because the mortar is used for bonding. further,
Some skill was required, and the cost had to be high.

In the above-mentioned method, in order to satisfy a demand for expressing a fine pattern or changing colors in small units, the size of tiles to be laid must be reduced, which requires more time and effort. However, recently, there has been a tendency to favor such patterns studded with fine stones.

Of course, because it is used as a road, weather resistance,
Needless to say, wear resistance and the like are required.

Therefore, in the industry, detailed work on site is easy,
There has been a long-awaited demand for a surface treatment method that does not require any skill and has an aesthetic appearance studded with fine patterns and fine stones.

[Means for Solving the Problems] In view of the above situation, the present inventor has completed the treatment method of the present invention as a result of earnest research, and the feature of the present invention is that an adhesive is applied to the surface of a pavement or the like. It is laid down, the granular material is adhered to the pressure-sensitive adhesive without gaps by utilizing the adhesive force of the pressure-sensitive adhesive, and a synthetic resin coat is applied thereon.

Here, the pressure-sensitive adhesive refers to a substance that can maintain the adhesive force for a long period of time, and a rubber-like substance is preferable. The pressure-sensitive adhesive may be a liquid or a sheet.
Examples of the sheet-like pressure-sensitive adhesive include a commercially available non-vulcanized butyl rubber sheet, and a material in which a net or a thread is interposed therebetween to increase the tensile strength.

Further, the pressure-sensitive adhesive may be applied to a plastic sheet or the like to a relatively large thickness. When there is no adhesive force (adhesive force) on the back surface, it is desirable to apply an adhesive on the back surface. In the case where the back surface of the sheet-shaped material has an adhesive strength, it is preferable that a release paper is adhered to the back surface for handling.

Of course, the pressure-sensitive adhesive is not limited to these, but may be any as long as it has the above properties.

This adhesive force allows the granular material to be placed on the adhesive and
When removing the excess, it is only necessary to have a fixing force enough to adhere to the extent that the necessary particulate matter is not removed at the same time, and it is not necessary to completely fix and fix the stone so that the resin hardens.

Laying means laying down, and here means pouring, coating or the like in the case of a liquid material, and placing it in the case of a sheet-like material.

The laying thickness of the adhesive is not particularly limited, and may be appropriately selected depending on the size of the granular material, the adhesive strength, and the like.
Usually, about 0.5 to 3.0 mm is sufficient.

Granular material refers to the shape and size of a pebble (2 to 10
mm). Of course, it may be somewhat flat or long. A typical example of this granular material is natural stone. Natural stones may be placed in various colors at random, or may be fixed colors. Further, a pattern may be made to appear only in a specific portion by using a stone of a specific color by using a pattern described later.

As the granular material, not only natural stone, but also a ceramic mixed with a pigment and fired, or a ceramic colored material may be used.

In order to adhere without gaps, it means that there is no exposed part of the adhesive on the adhesive, but it is theoretically impossible to have no exposed part at all, so it is said to be "almost all" Is the meaning of

Substantially the entire area means that there is almost no exposed part where a stone of the same size as the attached stone can enter.

As for the method of placing (adhering) the granular material, there is a method in which the granular material corresponding to the area of the pressure sensitive adhesive is carefully placed on the adhesive sequentially, but the granular material is excessively applied to the adhesive layer. The method of mounting and removing the excess (the amount not fixed by the adhesive) is simple.

This removal is conveniently and easily performed by a vacuum device. However, in this case, a vacuum pump is required.
It is also conceivable to use a smooth plate or the like to scrape off excess and move it to one side to remove it. This method is convenient because no special device is required.

Synthetic resin coating refers to dissolving, emulsifying, or dispersing a thermoplastic resin or the like with a solvent or the like, spraying or applying the same, covering the natural stone from above, and drying and solidifying it.
Although the synthetic resin for coating (coating) is dried and solidified even when left as it is, it may be forcibly dried by a dryer.
Further, a reactive curable resin may be used for coating.

As an example of the synthetic resin, an acrylic resin or an epoxy resin is preferable. This synthetic resin is usually transparent to show the color of natural stone, but may be colored by mixing a pigment. In particular, expressing a pattern with a part of it being colored will bring out another aesthetic appearance.

Further, in the present invention, a pattern can be expressed by using colored granular materials. This method will be described below.

First, an adhesive is laid on a pavement or the like. This is the same as described above. On top of this, a pattern (paper, plastic film, etc.) of a predetermined shape is placed. It is preferable that the back side of the paper pattern is subjected to a peeling treatment so that subsequent peeling becomes easy.

Next, the particulate matter is adhered to the pressure-sensitive adhesive layer not covered by the pattern paper without any gap from the top of the pattern paper, and then the excessive particulate matter is removed. Then, when the pattern is removed, no particulate matter is attached to the portion where the pattern was located. Granules of a different color from the first granules are placed and adhered to this portion, and excess is removed.

At this time, since the granular material does not adhere to the portion where the granular material has already adhered, it is possible to apply two colors according to the pattern paper. Of course, the color is not limited to two colors, and both may be a mixed color or a multi-color. For example, one is a mixture of dark colors and the other is a mixture of bright colors. Here, the mixed color refers to a mixture of granular materials of various colors.

By changing the shape of the pattern into joints such as bricks or tiles, or by using various graphic patterns, various patterns can be made to appear completely freely.

Also, by using two or more patterns instead of one pattern, it is possible to apply three or more colors (adhesion of particles of different colors).

The appearance of such a pattern is very useful on a pavement under an arcade or the like.

The method of the present invention, in order to finally coat the synthetic resin,
Granules do not come off or move.

Example FIG. 1 is a cross-sectional view showing the steps of the surface treatment method of the present invention.

FIG. 1A shows a state in which an adhesive 2 is applied to the surface of the pavement 1. FIG. 1B shows a state in which a large number of natural stones 3 are placed on the adhesive 2. In this state, the lowest stone is attached to the adhesive. And the removal tool 4 is about to begin removing excess natural stone. FIG. 1 (c)
The removing tool 4 removes the excess natural stone 3 and the treated surface is in a smoothed state. Next, a synthetic resin (polymethyl methacrylate or the like) 8 is spray-applied thereon from above by a spray device 9 (FIG. 1 (d)). Before the application of the synthetic resin 8, the stone is pressed from above to make it more smooth,
You may make it adhere a stone more firmly to an adhesive layer. FIG. 1 (e) shows a state in which the synthetic resin coating has been completed. Drying of the synthetic resin 8 may be natural drying or a dryer. Thus, the surface treatment of the present invention is completed.

Natural stones of fine size are randomly arranged on the surface,
It has an appearance similar to the washing method often used for the exterior of a conventional building, and has an excellent appearance.

Further, the stone does not shift or come off due to the presence of the eight coats of the synthetic resin. Also, cracks are less likely to occur in the treated layer due to the elasticity of the synthetic resin or the lower pressure-sensitive adhesive layer.

FIG. 2 is a sectional view showing the steps of another embodiment of the present invention.

FIG. 2A shows the same state as FIG. 1A. The pattern 5 is placed on the adhesive layer (FIG. 2 (b)).
The back surface of the pattern 5 has been subjected to a peeling treatment. On this, a stone 6 of a predetermined color (here, brown) is placed. And the first
Excess brown stone 6 is removed by the removal tool 4 in the same manner as in the case of the figure (FIG. 2 (c)). Since the upper surface of the pattern paper 5 has no adhesive strength, the stones thereon are removed. But,
Even if it remains, there is no problem because it can be removed together with the pattern 5. FIG. 2 (d) shows that the excess brown stone 6 has been removed and the brown stone 6 has adhered to the portion where the adhesive layer 2 is exposed without any gap.

Next, the pattern 5 is removed (FIG. 2 (e)). In this state, the brown stone 6 adheres only to the portion not covered by the pattern 5, and the adhesive layer is exposed in other portions. From above, natural stone of another color (here, black) is excessively placed (FIG. 2 (f)). Then, the excess black stone 7 is removed again by the removing tool 4, and then the synthetic resin 8 is applied by the spraying device 9 (FIGS. 2 (g) and 2 (h)). When the entire surface application is completed, the process is completed.

FIG. 3 is a plan view of a pavement or the like in the state of FIG. 2 (i).

 You can see that the joint pattern is clearly visible.

[Effects of the Invention] The surface treatment method for pavement of the present invention has the following great advantages.

The surface of the pavement etc. can be finished with simple work, and the appearance is very good.

In the method using the paper pattern, various patterns such as joints and mosaics can be easily formed on site.

Since small particles are spread over the surface, fine patterns and various colors can be expressed.

Since it is made of natural stone or ceramic and coated with a synthetic resin, it has excellent weather resistance and wear resistance.
