Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mat with grass, and a mat body 2 formed by collecting fiber pieces 1 made of fiber waste obtained by crushing waste tires and bonding them with urethane resin, with openings on the front and back sides. This relates to a mat with grass, which is characterized by having a large number of through holes 3 formed therein, and having grass 4 provided in the through holes 3.

Lawns are usually planted on the ground and grow so that almost the entire surface is exposed, but when the grass is trampled, the roots of the grass, which are crawling close to the ground, receive strong force from the ground and can be damaged. Not only is it easy to use, but especially when stepped on by spikes, the ground surface is dug up by the spikes and the roots of the lawn are easily killed.

Therefore, the grass on golf courses, which is susceptible to trampling and the effects of golf shoe spikes, has a short lifespan, with no growth.

The present invention has been made in view of the above-mentioned points, and provides a lawn with good growth without the risk of the roots of the lawn being damaged or dug up even when trampled or spiked. The purpose of this invention is to provide mats with attached mats.

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, since the one-component urethane resin has elasticity, it does not impair the cushioning properties of the mat body, which is an aggregate of the fiber pieces 1. In fact, the cushioning properties can be improved, and it is easier to handle than the two-component type, and curing can be easily performed by simply supplying moisture.

Therefore, in manufacturing the mat body 2, a moisture-curable one-component urethane resin solution is sprinkled onto the fiber pieces 1 obtained from waste tire pieces, and the fiber pieces are kneaded until the fiber pieces are wetted with the one-component urethane resin. After that, 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 kneaded material, 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 the voids between the fiber pieces 1 are porous.

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 5 will be mixed in, but even if some rubber pieces 5 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 5 are mixed in at a moderate amount, but it is preferable that an appropriate amount of rubber pieces 5 be mixed in to improve the cushioning properties of the mat body 2.

A large number of through holes 3 which are open on the front and back sides are punched in the mat body 2 obtained as described above.

Although the thickness, shape, and density of the through holes 3 are not limited, they are provided, for example, as shown in FIG. 2 a'Pb.

The mat body 2 with the through holes 3 drilled in this way is used by laying it out on the ground of a golf course, etc. The mat body 2 is laid on the ground and grass seeds are planted on the ground through the through holes 3. When the grass is sown and grown, the grass that grows inside the through hole 3 grows by crawling on the surface of the mat body 2, and eventually the grass grows on the mat body 2.
0 surface is covered with grass 4 as shown in FIG.

In this way, it is used as a lawn, and even if the spikes act, they will not reach the ground due to the thickness of the mat body, and the grass 4 inside the through hole 3 will be damaged by the spikes or the roots will be dug up. There is no matte body 2
Even if tread pressure is applied or spikes act on the grass 4 that has grown on the surface, the mat body 2 is an aggregate of fiber pieces 1, so it has elasticity and will not be dug up like soil. The roots of No. 4 will not be damaged or dug up.

In the above embodiment, the mat body 2 is spread on the ground and the grass 4 is grown from the ground through the through holes 3 to the surface of the mat body 20, but the grass 4 is planted directly on the surface of the mat body 2. You can.

That is, when planting the grass 4 on the mat body 2, first, lawn seeds are sown and planted on the surface of the mat body 20, and after the grass has germinated, liquid fertilizer is injected into the mat body 2, and the grass is allowed to grow. A mat having grass 4 planted on the surface thereof is obtained.

When the grass 4 grows in this way, the grass 4 also grows and enters the through hole 3, and the through hole 3 is covered with the grass 4.

Through holes 3 provided in the mat body 2, drainage is improved and the lawn 4
This will promote the growth of children.

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

Furthermore, since the mat body 2 is porous due to the voids V4 between the fiber pieces 1, it can contain liquid fertilizer well and the grass grows quickly.

In the case where the grass 4 is directly planted on the surface of the mat body 2, it is easy to carry because the grass 4 is integrated with the mat body 2, and the mat body 2 is an aggregate of fiber pieces 1. Because of this, it absorbs fertilizer well and does not require the use of soil, and can be used on balconies and rooftops, making it possible to use real grass on balconies or rooftops without using artificial turf as a substitute. It can be placed on the roof.

Note that the grass 4 may be formed on the surface of the mat body 2 by spreading grass on the surface of the mat body 20 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 2.

- -- As described above, the present invention provides a mat body formed by collectively bonding fiber pieces with a large number of through holes opening on the front and back sides, and providing grass in these holes to form a mat with grass. Therefore, even if tread pressure or spikes are applied, the tread pressure or spikes will not reach the ground due to the thickness of the mat body, and the grass inside the hole may be damaged or the roots may be dug up by the tread pressure or spikes. It is a material that can prevent the growth of grass, and there is no risk of stopping the growth of the lawn.Furthermore, the fiber pieces made of fiber waste obtained by crushing waste tires are aggregated and bonded to form a mat body. Since the mat body is an aggregate of fiber pieces, it has elasticity, but since the fiber pieces are obtained by crushing waste tires, some rubber pieces are also mixed in.
These rubber pieces can also give the mat a suitable amount of elasticity, and even if strong tread pressure is applied to the grass extending on the surface of the mat or spikes act strongly, this elasticity will cushion the mat. It is possible to prevent damage to the grass on the surface of the pine tree, and since the fiber pieces are aggregated and bonded with urethane resin to form a mat, the spikes will not damage the grass on the surface of the pine tree. Even if the fibers are caught on the mat, each fiber fragment is bound by urethane resin, which prevents the fiber fragments from being peeled off as if the surface of the mat body is being dug up. It can be prevented from being peeled off from the surface of the body, and the urethane resin that binds the fiber pieces at this time has elasticity itself, so that each fiber piece is bonded to form a mat body. However, the elasticity of the mat body is not impaired in any way.

Since it is not easily affected by tread pressure or spikes, the grass-covered mat of the present invention is suitable for use on the grass of a golf course where tread pressure or spikes are constantly applied to the grass. It is suitable for use on soiled areas that are subject to strong action, and allows lawns to grow smoothly even under very harsh conditions.

In addition, since the mat body is formed by collectively bonding fiber pieces as described above, it has elasticity and provides an excellent walking feeling, and also has excellent absorption of liquid fertilizer, allowing the lawn to grow quickly. It is something that can be done.
