Description

Artificial grass block using waste rubber chip {BLOCK HAVING ARTIFICIAL LAWN MAT USING WASTE RUBBER CHIP}

The present invention relates to an artificial turf block, and more particularly, to an artificial turf block using waste rubber chips.

Recently, artificial turf mats have been widely used as flooring materials for playgrounds, golf courses, children's playgrounds, and trails. Artificial turf has less maintenance cost than natural grass, and has the advantage of excellent shock absorption ability and good appearance compared to sand, cement and clay blocks, which are common flooring materials.

Such artificial turf may be installed by directly planting grass on a mat placed on the ground, but since such a form is inconvenient to install, it is common to install a plurality of artificial turf mats in which a grass portion and a mat portion are integrally installed on the ground. It is used a lot in form.

As the artificial turf mat, as shown in FIG. 1, there is an artificial turf mat formed by attaching the grass 20 into which the grass 21 is planted with an adhesive B on the mat portion M.

However, the adhesive (B) is not only harmful to the human body, the mat manufactured as described above has a limit in the bonding force of the mat portion (M) and the grass portion 20, so the grass portion 10 and the mat portion in accordance with long-term repeated use There was a limit to the durability of the artificial turf mat, such as the separation of (M).

For this reason, the mat part M formed by vulcanizing and mixing waste rubber and raw rubber without using an adhesive agent, and artificial turf 21 are planted on the upper part, and the mat part M is formed on the upper part of the mat part M. Has been presented artificial turf mat including the turf portion 20 is pressed and fixed in a heated state (see Republic of Korea Utility Model Registration No. 0281720).

However, the artificial turf mat described above has a structure in which the upper layer of the finished mat portion M is heated and melted at a high temperature, and the turf portion 20 is pressed and fixed thereto at high pressure, so that the artificial turf 21 is damaged. There was a concern.

For this reason, in order to prevent turf damage, the mat part M must be heated and melted away from the artificial turf 21 so that it cannot be applied to the mat part M having a predetermined thickness or more due to the limit of heat transfer. There was a limit.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an artificial turf block of a more robust structure without damaging the artificial turf.

In addition, another object of the present invention is to provide an artificial turf block to which a thicker rubber block portion can be applied.

Artificial turf mat of the present invention for achieving the above object,

A rubber block portion formed by molding a waste rubber chip and a binder powder for bonding the waste rubber chip to each other;

The artificial turf is planted on the top, and the artificial turf is positioned on the rubber block part and coupled to the upper part of the rubber block part with its molding.

The waste rubber chip is preferably composed of a granule chip and a flaky chip.

In addition, it is preferable that another rubber block portion made of fine chips and binder powder thinner than the chips of the waste rubber chip is interposed between the artificial turf portion and the rubber block portion.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, and the same reference numerals will be used for the same parts as those of the artificial turf block of the present invention.

In the present invention, the artificial turf portion refers to a mat-shaped member in which artificial turf made of a conventional material is planted. In addition, in the present invention, the block is a concept including not only a thin plate-like sheet or mat form, but also a form having a thickness much thicker than the sheet such as a rectangular parallelepiped shape. As will be described later, according to the present invention, since it is possible to produce products having various thickness specifications, in the present specification, in order to clarify the scope of the present invention, instead of the conventional mat part or artificial turf mat name, a rubber block part or an artificial grass block is used. The term is used.

Figure 3 is a schematic diagram showing the manufacturing process of the artificial grass block of the present invention.

As shown, the artificial turf 20 into which the artificial turf 21 is implanted is placed in the molding machine 200, and the waste rubber chip 11 and the binder powder are disposed on the grass-side opposite surface of the artificial turf 21. The composite powder mixed with (12) is laminated to a predetermined thickness.

The laminated artificial turf 20 and the composite powder are heated and pressurized at a predetermined temperature and pressure to form a rubber block 10 made of the composite powder on the artificial turf 20 and at the same time the artificial turf portion ( 20) and the rubber block portion 10 by pressing, the artificial turf mat of the present invention is produced.

The waste rubber chip 11 is chopped waste rubber such as waste tire into a predetermined size and a predetermined shape. As the binder 12, for example, a commonly used rubber binder such as TDI or MDI may be used, and the present invention is harmless to the human body because it can achieve the object of the present invention under low temperature and low pressure as described below. It is particularly preferable to use an MDI binder which can be applied even under low pressure.

The main feature of the present invention, by forming the rubber block unit 10 and the artificial turf unit 20 and the rubber block unit 10 integrally combined to produce a more simple artificial turf block structure In that it can.

In addition, the rubber block part 10 has a further feature in that the small waste rubber chip and the powdery binder are combined to prevent damage to the artificial turf 21.

As described above, the conventional artificial grass mat is to melt the finished mat portion (M), so very high temperature (180 ° C. or more) and pressure (180 ton or more) are required, which may damage the grass part 20. there was. However, the present invention takes a structure in which the waste rubber 11 in the form of a fine chip is bonded and formed by the powdery binder 12 and naturally bonded to the artificial turf portion 20 in the process, thereby reducing waste rubber. It is not necessary to have a high enough temperature to be completely melted, and only enough to be bonded to each other by the binder 12 (that is, a temperature at which the rubber chips 11 can be partially melted; about 120 ° C. or less). Only need. In addition, the present invention is because the artificial turf 20 is naturally coupled to the rubber block 10 in the molding process of the rubber block, it does not require a high pressure as in the conventional compression fixing method. According to the present invention, the artificial turf 20 and the rubber block 10 may be combined with a low pressure of 5-10 tons.

Particularly, since the waste rubber is in the form of a fine chip, and the fine waste rubber chip 11 and the fine powdery binder 12 are combined, the coupling reaction efficiency is greatly increased, so that even under the low temperature and low pressure described above. Molding of the rubber block 10 and the coupling of the artificial turf 20 can be made effectively.

In addition, when the appropriate binder 12 (eg, MDI binder) is selected, the molding temperature of the rubber block 10 and the bonding temperature of the artificial grass 20 may be lowered to about 100 degrees or less.

Therefore, according to the mechanism of the present invention, not only the molding of the rubber block part 10 and the artificial turf part 20 are combined, but also the artificial turf block can be manufactured under a much lower temperature and lower pressure than in the related art. Not only there is little fear of damaging the artificial turf 20, the productivity can be increased and the manufacturing cost can be significantly reduced.

Another feature of the present invention is that it is possible to produce products of various thickness specifications. That is, in the present invention, by simply adjusting the thickness (height) of the composite powder laminated on the back of the grass part 20, or by adjusting the pressure applied to the composite powder, the rubber block part 10 having various thicknesses and specifications is easily available. Can be prepared. Therefore, not only the sheet or mat form, but also the rubber block portion 10 having a shape such as a rectangular parallelepiped can be manufactured.

By adjusting the shape and size of the waste rubber chip applied to the present invention, the coupling effect of the molding of the rubber block 10 and the artificial turf 20 is further maximized, and the characteristics of the finished artificial grass block are also improved. do. That is, in Fig. 3, a so-called granule-type waste rubber chip 11 of circular, elliptical, or near rectangular shape is used. 11 ') is mixed and molded, compared to the rubber block portion 10 of the same thickness formed only by the granule-type chip 11, the bonding force is more excellent and the shock absorbing effect is further increased. In this type of rubber block 10, the chipping chip 11 'is further interposed between the granule chip 11 intervals, thereby further strengthening the chip-to-chip bonding, so that the molding efficiency is always maintained even under the same molding temperature and pressure.

In addition, as shown in FIG. 5, between the artificial turf portion 20 and the layer in which the granule and the chip-shaped chips are mixed, the finer chip 11 ″ and the binder powder 12 that are thinner than the chip 11 ′ are provided. When molded through the composite powder layer consisting of), it is possible to manufacture an artificial grass block 100 (see Fig. 6) of more excellent characteristics. Since the surface of the rubber block 10 in contact with the grass 20 is subjected to numerous repeated loads, it is essential to maintain a high surface hardness. Therefore, when the additional rubber block portion 10 'is formed between the composite powder layer as shown in FIG. 4 and the artificial turf portion 20 as shown in FIG. The hardness of the surface of the rubber block portion 10 'in contact with the portion 20 can be improved, and at the same time, the impact absorbing effect can be improved by the rubber block portion 10 formed by mixing the lower granule chip-shaped chips. . At this time, the binder 12 included in the upper and lower rubber block portions 10 and 10 'may be the same kind, but other types more preferable in accordance with the type and size of the flat chips 11' and 11 ''. Of course it can be used.

The size of the chip applied to the present invention is not limited to a specific range, and can be variously selected in view of the convenience of manufacturing and the use and characteristics of the artificial grass block. Typically, the granule chip 11 having a diameter of 5 to 8mm, in the case of the flap chip, the flap chip 11 mixed with the granule chip is 5 to 10 mesh, the fine flaky chip of the layer in contact with the artificial turf portion 20 (11 ') is recommended to use 16-20 mesh. In addition, in this invention, a chip | tip chip means that the length is at least 4 times or more compared with the thickness.

As described above, according to the present invention, an artificial turf block having a more rigid structure can be obtained while the artificial turf is hardly damaged.

In addition, the artificial turf block of the present invention, it is possible to apply a variety of forms of rubber block, it is possible to supply a product of various specifications according to the use and characteristics of the product.

In addition, the present invention has the advantage that it is possible to manufacture a more versatile and excellent artificial turf block by modifying the shape of the chip or the laminated structure of the rubber block portion.
