Description

Filler for artificial turf containing terpene {FILLER FOR ARTIFICIAL TURF CONTAINING TERPENE}

The present invention relates to an eco-friendly artificial turf filling material, and more specifically, by having a composition containing a terpene component, so as to increase antimicrobial properties, prevent a lot of rubber odor and high temperature deterioration in summer and prevent installation. It relates to a filler for artificial turf containing terpene to provide a comfortable environment for the side.

Artificial turf has the texture of natural turf, can be used for a long time, has a low maintenance cost, and prevents injury due to cushioning.

The artificial turf is artificially made of synthetic fiber and has the form of grass, which can always maintain the same color regardless of environmental conditions such as seasons and climate, and is relatively easy to construct and manage. For this reason, it is used as a substitute for natural grass, and is mainly installed in sports stadiums or indoor and outdoor areas where natural grass is difficult to grow.

The artificial turf is formed of a mat shape using synthetic resins such as polyvinylidene chloride (PVC), polyethylene (PE), and polypropylene (PP).

At this time, between the artificial turf includes a configuration in which the filler is filled to support the artificial turf and perform a buffer function against external force.

Incidentally, the artificial turf is made of a polymer resin such as polyethylene, polypropylene, nylon, and the like, and then is woven into a polypropylene or polyester foam paper to form an artificial turf pile by weaving in an upright shape, and the above In order to prevent the artificial turf pile from being pulled out of the artificial turf base, a coating material made of SBR (styrene butadiene rubber)-based Latex or polyurethane material is applied to the artificial turf base (back coating) to prevent the artificial turf from being pulled out of the artificial turf base. Artificial turf having a mold structure is manufactured.

When such artificial turf is used for various sports stadiums, a base layer such as aggregate or asphalt or concrete must be formed, and an auxiliary facility for drainage must be provided, and after installing an artificial turf mat on such base layer, artificial turf In order to maintain and protect the upright state of the pile, a silica sand layer is formed by filling the silica sand between the artificial turf piles, and in addition, a filler layer having elasticity is formed on the silica sand layer to improve the performance and to increase the shock absorbing power. This is common.

Conventional artificial turf mats have only two types of rear coating materials: latex and polyurethane. Among them, latex coating materials have had a problem in exerting strong adhesion and drawing power, and long-term climatic conditions such as rain, snow, high temperature, and low temperature. Due to exposure to, the dropping of the pull force has been a problem, and due to the peculiar smell of rubber chemicals, limitations have been pointed out in reducing fatigue of artificial turf users. In addition, when the artificial turf reaches the service life, it contains problems that are difficult to recycle when discarded. On the other hand, polyurethane has the advantage of exerting durability even in long-term climatic conditions, but the biggest problem is that it cannot be used universally due to its high price.

Accordingly, in connection with artificial turf, which has been increasing in popularity, various studies have been conducted to improve the durability of artificial turf and to manufacture the artificial turf to be environmentally friendly and improve antibacterial properties.

It is used in powder form.

The elastic material can be used alone among each of the above-listed materials, and sometimes the materials can be mixed and used as needed.

For example, two or more of synthetic rubbers of Styrene Ethylene Butylene Styrene (SEBS), Stylene Butadiene Rubber (SBR), and Ethylene Propylene Diene Monomer (EPDM) can be selected and mixed, and sometimes SBS (Styrene Ethylene Butylene Styrene), SBR (Stylene Butadiene Rubber) and EPDM (Ethylene Propylene Diene Monomer) can be used by mixing one or more selected from unvulcanized natural rubber or cork, and sometimes unvulcanized natural rubber and cork.

Here, it will be said that these elastic materials can be mixed and used in a weight ratio of approximately 1:1, but it is not particularly limited thereto.

In the case of manufacturing the filler with only the linear low-density polyethylene, it is difficult to secure a proper toughness and it is difficult to maintain a predetermined shape. Thus, by mixing the linear low-density polyethylene with the high-density polyethylene and ultra-high molecular weight polyethylene, it is possible to maintain the shape of the filler and secure appropriate mechanical strength.

The polypropylene-based resin preferably has a weight average molecular weight of 80000 to 100,000 and a melt index of 10 to 100g/10mim, and may be any one group selected from polypropylene homopolymers, polypropylene random copolymers, and polypropylene block copolymers. .
