Description

Artificial turf structure for ground

The present invention relates to an artificial turf structure, specifically, the filler constituting the filling layer (2) is (2a) graft copolymerized with natural cork powder with styrene-based thermoplastic elastomer, synthetic resin, MAH (Maleic Anhydride acid) It is made of a mixture of elastomer, flow paraffin oil, and minerals. Its performance is similar to that of natural cork, and there are no heavy metals or toxic chemicals that are harmful to human body. Natural cork absorbs moisture in rainfall or snowfall or in the air to maintain moisture at all times, and to moisten artificial turf filaments without moisture in the process of slowly releasing moisture when the air temperature rises. Therefore, artificial turf has a moisture moisturization and feel similar to that of natural grass, and the effect of preventing artificial turf from becoming hot is expressed, and the filling material (2b) is natural silica sand, artificial silica sand, and earth sand. This relates to an artificial turf structure exhibiting elasticity and drainage.

Typically, artificial turf structure is composed of a synthetic mat, PE, Nylon, P.P (Polyethylene, Polyamaid, Polypropylene) filaments protruding similar to natural grass;

As the conventional filler, silica, earth and sand, elastomer (SEBS, EPDM, etc.), coconut powder, or mixtures thereof have been widely used.

The elastic polymer is natural rubber, synthetic rubber or thermoplastic resin.

However, when the elastic polymer is used as the filler, the elasticity of the artificial turf structure is improved, but chemicals harmful to the human body are discharged from the elastic polymer, and the odor or odor inherent to the chemical is severe, which is harmful to the human body and is not hygienic, and also the humidity There was a problem that it is difficult to express a soft and moist touch such as natural grass because of no retention.

In addition, when salt is mixed with natural vegetable powder, cocopeat powder, coco fiber powder, coconut powder, coco shell powder, and earth, silica, and cryoprotectant, moisture in the air or salt component in rainy weather are decomposed to prevent freezing. There is a problem that is difficult to maintain the effect.

In addition, when using a mixture of the granular coconut-based natural cork of the vegetable material and sand as a filler, there is a problem that the filler is excellent in drainage and humidity retention but inferior elasticity.

Korean Patent Application No. 10-2008-0115058 proposes a method of using a chip-shaped filler made of a mixture of thermoplastic resin and loess, but since some of the filler is composed of thermoplastic resin, it is harmful to human body. The problem of chemical emissions could not be solved.

Korean Patent Application No. 10-2006-0136245 proposes a method of impregnating a coconut chip and a cork chip in an adhesive and using the same as a filler, but a problem in which harmful chemicals are emitted due to the use of the adhesive is not solved.

In Korean Patent Application No. 10-2009-0035087, a vegetable powder, cocopeat powder, coco fiber powder, coconut powder, coco shell powder, and earth, silica, and earth sand are mixed, and salt is mixed with a cold freezing agent. Although a method of using a filler is proposed, the problem of soil and natural rain mixed with soil and natural vegetable powders is partially decomposed, and salts are also decomposed. Could not solve enough.

Another conventional technique proposes a method of using a granular natural cork or coconut-based vegetable material and a mixture of sand as a filler for the artificial turf structure, but the method is strong because the natural cork or coconut-based vegetable material is in the form of granules. Rainwater that could not be penetrated into the pitching layer of the rainy day in the rain flows into the drainage pipe in a short time, floats over the filament, and floats with the rainwater, causing the filling material to be severely worsened, and the coconut-based vegetable material, which is the filling material, decomposes and decays.

The present invention is to provide an artificial turf structure free of chemicals harmful to the human body from the filler.

In addition, the present invention provides moisture to the artificial turf from the filler material artificial turf to have a moisturizing effect, such as natural grass and to provide an artificial turf structure that the effect of preventing the artificial turf is warmed to the solar heat.

In another aspect, the present invention is to provide an artificial turf structure of the effect of preventing the thermoplastic resin warmed to the sun from the filler and prevent freezing at cold temperature.

In order to achieve such a problem, in the present invention, the granules (i), natural silica powder (i) contained in the thermoplastic resin composition (i) as a filler, and (i) granules, silica sand or earth sand or a mixture thereof are artificial. Form a filling layer of turf structure.

The present invention is hygienic because the filler is not detected harmful chemicals.

In the present invention, the independent pores and densities of natural cork in the filler are excellent for moisture-proof insulation insulation, but the broken gaps on the surface provide moisture to the artificial turf filaments without moisture in the process of absorbing and releasing moisture. Artificial grass is moisturized to express the touch like natural grass because it plays a role of cooling heat heated by solar heat.

In addition, the present invention can effectively prevent the floating (floating) and loss of the filler as the weight specific gravity of the material containing natural cork in the thermoplastic resin composition is 1.4 (± 10%).

In addition, the present invention contains a natural cork in the filler (ⅰ) natural cork characteristics, such as natural, fouling resistance, deodorant, sound absorption, antibacterial, anti-fungal properties, such as anti-corrosive properties, so that after a certain period of recovery and recovery It is an environmentally friendly filler
