Description

Modular hybrid turf comprising natural and artificial turf and method for manufacturing the same

The present invention relates to a modular hybrid turf, and relates to a modular hybrid turf including natural and artificial turf and a manufacturing method thereof.

Although natural turf has many advantages in terms of being environmentally friendly, it is difficult to use as a playground or sports facility because it is difficult to manage and often gets trampled on when used.

Accordingly, artificial turf that embodies the tassel of natural grass with a thin film is widely used. For artificial turf field, an artificial turf mat planted with artificial turf tufts is laid on a compacted layer of soil, and silica sand is laid between the tufts of artificial turf planted on the mat to a predetermined thickness to make the tufts of artificial turf stand upright while simultaneously weighing the weight of the turf sand. It is made by fixing the artificial turf mat to the floor by using, and laying rubber chips for shock absorption again on the silica sand layer. Here, the artificial turf mat planted with artificial turf tufts has a structure in which the artificial turf tufts pass through and are fixed in a U-shape on a bubble fabric knitted with fibers such as PP, PE or PET, and the artificial turf tufts planted on the back side of the mat are used. In order to prevent pulling out, a back coating is performed using a binder. In addition, since the back coating causes a decrease in drainage of the artificial turf, the mat is perforated to solve this problem.

Such an artificial turf field has the advantage of being easy to install and maintain and can be used for a long period of time, but as an artificial structure, not only does it have a low eco-friendly sensibility, it is difficult to realize the texture of the grass, and it is also difficult to implement the texture of the grass. There are problems such as inconvenience and generation of microplastics due to long-term use.

There is a continuing demand for a natural-artificial turf hybrid playground by combining artificial turf and natural turf to solve these problems.

Korean Patent No. 2168800 discloses a hybrid turf module that sows turf, grows it to a previous level, and then plants artificial turf in the soil where the grass is planted. This method has a problem in that long-term stable vegetation of natural grass is difficult because there is no protection device for natural grass.

Korean Patent No. 2265557 discloses a hybrid grass module in which a natural grass module in which natural grass is planted is formed on a double perforated support plate, and an artificial grass module in the form of a perforated bubble paper is attached to the natural grass module.

However, this method has a very complicated structure, and if installed before the natural grass grows for a certain number of weeks, the natural grass may be trampled on and die, so it takes a long time to manufacture, and even if installed after the grass grows, artificial turf There is a problem that the natural turf growing between the modules may wither due to being pressed by the artificial turf module.

An object to be solved by the present invention is to provide a new hybrid type grass module in which artificial turf and natural grass are vegetated together.

Raw material

Artificial turf liquor is prepared by mixing 1000 parts by weight of polyethylene (Dow 8003) with 30 parts by weight of a green pigment, 10 parts by weight of a thickener, 5 parts by weight of an antifoaming agent, 10 parts by weight of a UV stabilizer, and 30 parts by weight of a flame retardant, was extruded with a twin extruder equipped with a mold having a rhombic hole.

The protruding perforated support plate was manufactured by melting polyethylene for injection and injecting it using a mold having a cavity corresponding to the protruding perforated support plate.

As shown in FIGS. 1 and 2, the protruding perforated support plate 100 has a square shape with the hollow protrusions 120 having a cylindrical lower part and a hemispherical upper part on the square supporting plate 110 at equal intervals on the front and rear left and right. , and the circular perforation holes 130 having the same direct diameter are displaced in a square shape while forming the same intervals in the front and rear, left and right, and one circular perforation hole is arranged in the center of the square composed of four hollow protrusions 120. achieve

The diameter and height of the lower cylinder 121 of the hollow protrusion 120 are 10 mm, respectively, the lower diameter of the upper hemisphere 122 is 10 mm, the height is 5 mm, and the diameter of the circular drilling hole 130 is 10 mm. achieve

As shown in FIG. 3 , artificial turf tufts 200 are tufted to the hemispherical portion of the hollow protrusion 120 of the protrusion-shaped perforated support plate 100 by tufting. The artificial turf tassel tufted protrusion-shaped perforated support plate 100 has artificial turf tufts 200 and hollow protrusions 120 on the inner surfaces of the hollow protrusions 120 to prevent the tufted artificial turf tufts 200 from falling out. The inner surface is coated with adhesive.

As shown in FIGS. 4 and 5, the bonding between the artificial turf tufts 200 and the hollow protrusions 120 is performed by placing the hollow protrusions 120 downward, then dropping a liquid adhesive from the bottom and curing it.
