Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a rubber mat and double rubber mat using old tires, and is used for golf driving ranges, batting centers, locker rooms of baseball stadiums, roads, floors, etc. It is something.

(Prior Art) The present applicant has developed various types of mats using old tires, but in all of the previous ones, old tires were cut into long strips, and the strips a were cut into several pieces as shown in Figure 1 A. Line them up and connect them with wire b, or use strips a
further cut to make a short piece c, and arrange the short piece c and the uncut long piece a as appropriate as shown in Figure 1 C.
These are connected with wire b.

However, since these are connected by wire b, when used as a scaffolding mat at a golf driving range, the wire b may pass through and wear out at a certain point, or if the damage is severe, the wire b may protrude outside from the worn place. It was hot.

Conventionally, the surface of a carcass cut from an old tire is brushed and bonded to a substrate with an adhesive, or felt made of thermoplastic fibers obtained by unraveling old tire cords is laminated with a reinforcing material. death,
There are also reinforced plastics made by heating and melting thermoplastic fibers.

(Problems with the prior art) The first mat of the prior art has a problem in that it is difficult to withstand long-term use, and it is dangerous if the wire b protrudes.

The second conventional technique involves bonding the carcass portion to the substrate using an adhesive, and therefore has a drawback in the strength of the bonded portion.

The third type of conventional technology utilizes only the cord part of the old tire, and is only used to manufacture reinforced plastic.
It could not be used as a rubber mat as it was.

(Objective of the Invention) The object of the present invention is to provide a rubber mat and a double rubber mat which solve the problems of the conventional products described above, make effective use of old tires, and have excellent strength.

(Means for Solving the Problems) The rubber mat described in claim 1 of the present invention is obtained by cutting the part of an old tire in which the canvas is built into long strips as shown in FIG. 1(b). Two or more pieces 3 are used, and the cut pieces 3 are lined up on the rubber plate 1 so that the canvas 6 is oriented vertically and the side surfaces 3a of adjacent cut pieces 3 are in contact with each other, and pasted on the rubber plate 1 with adhesive. As shown in FIG. 1C, this is heated and pressurized to weld the rubber parts of the bonded parts together, thereby integrating the bonded parts.

The double rubber mat described in claim 3 of the present invention uses two or more cut pieces 3 obtained by cutting the part of an old tire in which the canvas is built into long pieces as shown in FIG. Canvas 6
Rubber plates 1 are arranged on the rubber plate 1 so that the sides 3a of adjacent cut pieces 3 are in vertical orientation and the side surfaces 3a of adjacent cut pieces 3 are in contact with each other.
The two mats are pasted together with adhesive, and then heated and pressurized to weld the rubber parts of the two pasted parts together to form a rubber mat in which the pasted parts are integrated, and the rubber plates 1 of these two mats are stacked one on top of the other. The rubbers of both rubber plates 1 are welded together by heating and pressurizing them.

(Example) 2 to 4 show various embodiments of the present invention.

The rubber plate 1 shown in Figure 2A is as shown in Figure 2B.
Apply an appropriate adhesive 2 such as rubber glue or resin adhesive to the surface of the tire, and then cut the part of the old tire containing the canvas (reinforcing fibers inside the tire, generally made of nylon) into long strips. Dori cut piece 3
Use two or more of them, and attach them to the rubber plate 1 side by side so that the canvas 6 is oriented vertically and the side surfaces 3a are in contact with each other, and then place them between the press stand 4 and the mold 5 as shown in Fig. 2C. The rubber plate 1 and the cut piece 3 are welded to each other and integrated by applying pressure while heating the rubber plate 1 and the cut piece 3.

In the case of Fig. 3A, cut pieces 3 obtained by cutting the part of an old tire containing the canvas 6 into long strips are pasted on both sides of the rubber plate 1 as shown in Fig. 3B, and then cut by heating and pressurizing them. The pieces 3 are welded to both sides of the rubber plate 1.

In the case of Fig. 4 A, prepare two mats shown in Fig. 2 A, overlap the rubber plates of each mat as shown in Fig. 4 B, and stick them together with adhesive. The overlapping parts of the rubber plates 1 are welded to each other.

The rubber plate 1 used in the present invention preferably has a thickness of, for example, about 2 to 3 mm, and the cut piece 3 has a thickness of 9 to 10 mm.
It is desirable that the thickness be approximately the same. In this way, when the cut pieces 3 are attached to the rubber plate 1, the total thickness will be about 11 to 13 mm, but by heating and pressurizing it, the rubber of both pieces will fuse together, so the finished mat The thickness is about 9 to 10 mm. With this thickness, it is easy to lay, has sufficient strength, and has a good elastic feel when stepped on.

The cut piece 3 is used by cutting the part of the old tire in which the canvas 6 is embedded. Moreover, the cut pieces 3 are arranged on the rubber plate 1 so that the canvas 6 is oriented vertically as shown in FIG. If the canvas 6 is placed horizontally as shown in FIG. 5, the strength will not be sufficient.

(Effects of the Invention) The pine and double pine of the present invention have the following effects.

(1) The cut piece 3 of the part where the canvas 6 of the old tire is built and the rubber of the pasted part of the rubber plate 1 are welded to each other, so the bonded parts of the two become integrated, and the cut piece 3 becomes separated by use. Although the adhesive may wear out, the adhesive will not peel off.

(2) The cut piece 3 is a part of the old tire in which the canvas 6 is embedded, so it has excellent strength unlike a rubber-only one, and the canvas is not the only thing that needs to be taken out and used. Since the rubber covering the canvas is used, a rubber mat that is highly elastic and easy to walk on can be obtained. Therefore, even if this mat is used, for example, as a scaffolding mat at a golf driving range, it can be used for a long period of time (3 to 4 times as long as the conventional mat shown in FIG. 1).

(3) Place the cut piece 3 on the rubber plate 1 so that the side surfaces 3a are in contact with each other.
Because they are arranged on top of each other, the top surface of the pine becomes flat, making it easier to walk on.

(4) Since the cut pieces 3 are arranged on the rubber plate 1 so that the canvas 6 is oriented vertically, it is strong and durable.

(5) Traditionally used as scaffolding mats for golf driving ranges.
A rubber plate of about 20 mm was used, but as it was used, the parts that were stepped on by the spikes became thinner, and the parts swelled and were pushed upwards or dented, making them extremely difficult to use. However, with the pine of the present invention, such a problem does not occur at all.

(6) As shown in Figures 3B and 4B, if the cut pieces 3 are welded to both the front and back sides of the rubber plate 1, both sides can be used, so the cut pieces 3 are welded only to one side of the rubber plate 1. It can be used for twice as long and is very economical. The thicker it is, the more elastic it is, making it easier to walk on and less tiring.
