Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mat with grass, and a mat with grass on the surface of a mat body 20 formed by collecting fiber pieces 1 made of fiber waste obtained by crushing waste tires and bonding them with urethane resin. 3
The present invention relates to a mat with grass, which is characterized by being planted with grass.

Grass is usually planted and grown on the ground, but when the grass is trampled, the roots of the grass creep close to the ground, so they are easily damaged by the strong force between them and the ground, and they are easily damaged by golf shoes. When stepped on by spikes such as these, the ground surface is dug up, causing roots to wither and growth to stop, and replanting the lawn requires a great deal of effort.

In addition, in recent years, it has become popular to lay so-called artificial turf, which is made of synthetic resin material processed to resemble a lawn, on balconies and rooftops in order to create a garden-like feel on balconies and rooftops, but this artificial turf is just a synthetic resin material. Since it is a processed product, there are limits to how much it can produce a natural feel.

The present invention has been made in view of the above points, and it is difficult to damage the roots of the lawn even when trampled on it, and it is extremely easy to replace the lawn.In addition, it is a natural material that can be used on balconies and rooftops. It is an object of the present invention to provide a mat with grass on which it is possible to lay a lawn, and which also allows the grass to grow well.

The present invention will be explained in detail below with reference to Examples.

The mat body 2 is formed by gathering a large number of fiber pieces 1 in an entangled state and bonding them with an adhesive or the like.The fiber pieces 1 are made of recycled tires such as automobile tires. It is preferable to use it from the viewpoints of saving resources by recycling waste tires and being able to obtain it at low cost.

That is, the tire cord for reinforcing the tire contained in the waste tire is separated from the waste tire pieces obtained by cutting and crushing the waste tire, and the fiber waste of the cut tire cord is divided into fiber pieces 1. It is used as

As the adhesive for bonding the fiber pieces 1, it is preferable to use a urethane resin, especially a moisture-curable one-component urethane resin.

When a one-component urethane resin is used as a bonding adhesive for the fiber pieces 1 in this way, the cushioning properties of the mat body 1, which is an aggregate of the resin pieces 1, are not impaired because the one-component urethane resin has elasticity. At the same time, it can actually improve the cushioning properties, and it is easier to handle compared to two-component types.
Curing can also be easily carried out by simply supplying moisture.

Incidentally, as the fiber pieces 1, it is also possible to use those produced as waste fiber waste from a textile factory.

Therefore, in manufacturing the mat body 2, a moisture-curable one-component urethane resin solution is sprinkled onto the fiber pieces 1 obtained from scrap tire pieces until the fiber pieces are wetted with the one-component urethane resin. After kneading, the resulting kneaded product is placed in a mold having a release layer on the inner surface, and water is sprinkled onto the kneaded product to supply moisture.

Next, after pressurizing the mixed wire, the one-component urethane resin is cured by curing for approximately 24 hours to form a mat body 2 in which the fiber pieces 1 are bonded with the one-component urethane resin, and then the mat body 2 is molded. Release from the frame.

The mat body 2 is formed by intertwining and bonding the fiber pieces 1, and is porous due to the voids between the fiber pieces 1.

In addition, when providing a mold release layer on the inner surface of the mold, it is sufficient to apply a mold release agent to the inner surface of the mold or to lay down a film with good mold release properties such as polyethylene film. The mat body 2 can be easily released from the mold by lifting the upper part of the film that has come out of the mold.

Further, the mat body 2 can be mass-produced by placing a mixture of fiber pieces 1 and one-component urethane resin liquid in a mold, supplying moisture, and then performing the above-mentioned treatment while heating while pressurizing.

Here, when separating the fiber pieces 1 from the scrap tire pieces, it is inevitable that some rubber pieces 4 will be mixed in, but even if some rubber pieces 4 are mixed, the porosity due to the gaps between the fiber pieces 1 will not be hindered. There is no problem as long as the rubber pieces 4 are mixed in at a moderate amount, but it is preferable that an appropriate amount of rubber pieces 4 be mixed in to improve the cushioning properties of the mat body 2.

Grass is planted on the surface of the mat body 20 obtained as described above. In planting the grass, first, lawn seeds are sown and planted on the surface of the mat body 2, and after the grass germinates, the grass seeds are planted on the surface of the mat body 2. Inject liquid fertilizer into
The grass is grown to obtain a mat with grass 3 planted on the surface of the mat body 20 as shown in the attached drawing.

At this time, it is best to inject fertilizer after the lawn has germinated; if it is injected before it germinates, the lawn may have difficulty germinating.

Moreover, since the mat body 2 is porous due to the voids between the fiber pieces 1, it can contain liquid fertilizer well and the grass grows quickly.

Note that the grass 3 may be formed on the surface of the mat body 20 by spreading grass on the surface of the mat body 2 and allowing it to grow.

It is also possible to cultivate small plants other than grass that grow by crawling on the surface of the mat body 20.

In the mat with grass thus obtained, the grass 3 is planted on the mat body 2, so that grass can be laid anywhere by simply laying the mat body 2,
Furthermore, when replacing the lawn, it is sufficient to simply replace the mat body 2.

As described above, in the present invention, a grass mat is constructed by planting grass on the surface of a mat body formed by collectively bonding fiber pieces, so that the grass can be integrated with the mat body. Just by laying this mat, you can lay the grass anywhere you want, making the work of laying the grass extremely easy. It's extremely easy to do.

In particular, since the lawn is integrated into the mat, it can be carried freely, and since the mat is a collection of fiber pieces, it absorbs fertilizer easily and does not require the use of soil. It can be used by laying it on a rooftop, and it is possible to lay real grass on a balcony or rooftop without using artificial grass as a substitute.

In addition, since the fiber pieces made of fiber waste obtained by crushing waste tires are collectively bonded to form a mat body,
The mat body has elasticity because it is an aggregate of fiber pieces, but since the fiber pieces are obtained by crushing waste tires, some rubber pieces are also mixed in, and this rubber The pieces can give the mat body appropriate elasticity, and the rubber pieces can prevent the fiber pieces from being compressed and crushed, and even if strong stepping pressure is applied to the mat body with spikes, etc. Due to its elasticity and cushioning effect, grass roots are less likely to be damaged.Furthermore, since the fiber pieces are aggregated and bonded with urethane resin to form the mat body, the spikes are not attracted to the fiber pieces on the surface of the mat body. Even if it acts like hanging, each fiber piece is bound by urethane resin, which prevents the surface of the mat body from being dug up by the spikes, and there is no risk that the roots of the grass will be dug up and exposed. The urethane resin that binds the fiber pieces has elasticity itself, and even if the fiber pieces are combined to form a mat body, the elasticity of the mat body will not be impaired in any way. The mat with grass of the present invention is suitable for use on the grass of a golf course where the grass is constantly subjected to tread pressure and spikes, and is particularly suitable for use on playing grounds that are subject to strong such effects. This allows lawns to grow smoothly even under such harsh conditions.
