Description

Synthetic grass with resilient rice hulls layer

The present invention relates to a filler for artificial turf, and more particularly, to a filler for artificial turf using chaff.

Lawn used for sports or landscaping is divided into natural grass and artificial grass.

In the case of natural grass, the maintenance cost is high, and it does not grow well in the shaded part of the stadium. In addition, the natural grass surface has a problem that the quality is deteriorated due to the intense use of the artificial turf in recent years.

Artificial turf is installed by arranging carpet-type pile fibers with flexible backing material on easy-to-drain and dense members, such as small aggregates or other stable foundation layers, and pile fibers that are well-established artificial ribbons that represent turf grains. Has a column. In addition, in order to provide the elastic force of the stadium, it is used by mixing solid particles such as sand or slag particles together with elastic particles such as broken rubber particles.

In particular, rubber particles that provide elastic force are mainly used to scrap waste tires.

However, rubber chips used as fillers have the advantage of increased elasticity and recycling of resources. However, they are difficult to use for a long time due to their low abrasion resistance. Hazardous substances from waste tires or rubber chips can cause environmental pollution. It also causes harmful pollutants to those who use the stadium.

An object of the present invention for solving the above-mentioned problems is to remove the harmful elements by the filler formed by rubber chips such as waste tires, and to maintain the elastic force as before, but using chaff having eco-friendly and non-toxic material The purpose is to apply fillers to artificial turf.

Artificial turf formed chaff elastic layer according to the present invention for solving the above problems, the ground drainage layer; It is installed on top of the ground drainage layer, and the fiber bubble paper woven a plurality of fiber piles; A fiber pile fixing layer formed to fix the fiber pile and formed under the fiber foam paper; A silica sand layer filled between the fiber piles on the fiber base paper; It is formed on top of the silica sand layer, the chaff elastic layer is filled with chaff to provide elastic force.

Here, the rice hull elastic layer is characterized in that the pressure treatment by the roller of the weight.

According to the configuration of the present invention described above, to remove the harmful elements by the filler formed by rubber chips such as waste tires, and to maintain the elastic force as before, but to provide an artificial turf filler using chaff having an environmentally friendly and non-toxic material It becomes possible.

Hereinafter, with reference to the accompanying drawings to look at the structure and effect of the artificial turf according to the present invention.

1 is a structure of artificial turf with chaff elastic layer formed in accordance with the present invention, showing a double fiber pile structure, Figure 2 is a structure of artificial turf with chaff elastic layer formed in accordance with the present invention, a single fiber pile The structure is shown.

1 and 2, the artificial turf with the rice hull elastic layer is formed, the ground drainage layer 110, fiber bubble 130, fiber pile fixing layer 120, silica sand layer 140, rice hull elastic layer 150 And fiber piles 160 and 170.

Ground drainage layer 110 may be composed of a pitcher cone, asphalt concrete or aggregate layer that can be well permeated with rain water or water.

The fiber bubble paper 130 is formed on the ground drainage layer 110, and may be formed of a polypropylene material, as shown in FIG. 1, the first fiber pile 160 and the second fiber pile 170, FIG. The fiber pile 170 as in the layer is woven. The fiber bubble 130 is generally formed with a plurality of drain holes so that rain water, etc. in the rain can be drained to the bottom.

The fiber piles 160 and 170 are made of a material such as polypropylene or polyethylene.

The fiber pile fixing layer 120 allows the fiber pile to be fixed in rows in an artificial ribbon form, and is generally made of a material such as a ladex or polyurethane layer or a nonwoven fabric.

The silica sand layer 140 is filled between the plurality of fiber piles 160 and 170 woven on the fiber bubble paper 130 after the fiber bubble paper 130 is installed on the ground drainage layer 110.

Silica sand filled in the silica sand layer 140 is sufficient in the content of silicon dioxide, it is preferable to use a dry silica of the spherical body for the safety of the user.

The chaff elastic layer 150 is formed on the top of the silica sand layer, and is an elastic layer filled between the fiber piles 160 and 170 and is made of chaff. In order to prevent the chaff constituting the chaff elastic layer 150 is lost by the wind or floated in the rain during the rain or lost by the use of the stadium, it is preferable to form by pressing the appropriate moisture with a weight roller.

As chaff used in the present invention, chaff is used as it is in a natural state generated by refining rice ears. The rice husks have their own elasticity because they have a space inside the rice bran, and may vary in size depending on the rice variety. The chaff may also have a crushed and pressurized form, and may provide improved durability by using the crushed and pressurized chaff, and the chaff may be a colored chaff.

In this way, the fiber piles 130 and 170 are woven with fiber piles 160 and 170 on the ground drainage layer 110, and the silica sand between the fiber piles 160 and 170 on the fiber foam 130. The artificial turf having the chaff elastic layer 150 formed on the layer 140 and the silica sand layer 140 has a cohesive force due to the weight of the chaff elastic layer 150 itself and a roller press and a chaff elastic layer, such as a soccer field or a baseball field. A separate adhesive is adhered to the upper portion of the ground drainage layer 110 by the weight of the fiber bubble paper 130, including the weight of the silica sand 140 and the weight of the fiber pile (160, 170) formed on the lower portion of the 150 B. It can be easily packaged without fixing means, and the fiber bubble cloth 130 and the ground drainage layer 110 are more closely contacted by the pressure applied from the upper side, so that the artificial turf can be ground by manpower unless the force of the artificial machine is applied. It cannot be separated from the upper portion of the drainage layer 110.

In addition, the elastic layer used as a rubber chip, such as causing a bad smell and harmful elements in the air to reduce the exercise force for the stadium users, but the chaff elastic layer according to the present invention has a natural chaff has a chaff as a natural material In addition to providing a resilient force can double the exercise power, as well as non-toxic effects on the health of the stadium users are not at all.

Looking at the installation process of the artificial turf formed chaff elastic layer according to the present invention, first, the ground drainage layer 110 consisting of a pitcher cone, ascon or aggregate layer that can be well permeated with rainwater or water, and the fiber pile 160, The lower portion of the 170 is formed in the form of artificial ribbons to form a fixed fiber pile fixing layer 120 and the fiber pile 160, 170 woven fiber bubble paper on the ground drainage layer (110). Subsequently, the silica sand layer 140 is filled between the plurality of fiber piles 160 and 170 woven into the fiber base paper 130, and the natural chaff is filled on the filled silica sand layer 150 by an appropriate thickness. Using a predetermined weight roller, the chaff layer is filled with moisture and pressurized to an appropriate pressure to form the chaff elastic body 150.

Although the preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the above-described technical configuration of the present invention may be embodied by those skilled in the art to which the present invention pertains without changing its technical spirit or essential features of the present invention. It will be appreciated that the present invention may be practiced as.
