Description
The present invention relates to an environmentally friendly artificial turf mat and a method of manufacturing the same. More particularly, the present invention relates to an environmentally friendly artificial turf mat, which is made of an environmentally friendly material and improves the adhesive strength to the paper, Friendly artificial turf mat and a manufacturing method thereof.
The artificial turf may be manufactured by manufacturing an artificial turf yarn with a polymer resin such as polyethylene, polypropylene, nylon, etc., and then tufting the artificial turf yarn into a polypropylene or polyethylene base fabric to form an artificial turf file, Artificial turf mats are produced by back coating artificial turf bubbles with a coating made of latex or polyurethane material of styrene butadiene rubber (SBR) type on artificial turf base so as to form a pulling force so as not to be pulled out from the turf.
In order to use the synthetic grass mats for various athletic field applications, a base layer such as aggregate, asphalt, and concrete should be formed, and an accessory for drainage should be provided. In addition, an artificial grass mat is installed on the base layer, To maintain the upright state and improve the performance and to prevent injury by raising the shock absorbing power.

According to the eco-friendly artificial turf mat of the present invention having the above-described structure and the method of manufacturing the eco-friendly artificial turf mat of the present invention, the eco- There is an effect.
The effects of the present invention are not limited to those mentioned above, and other solutions not mentioned may be clearly understood by those skilled in the art from the following description.
1 is a cross-sectional view illustrating an embodiment of an environmentally friendly artificial turf mat according to the present invention.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings and the following description. However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Rather, the embodiments disclosed herein are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
1 is a cross-sectional view illustrating an embodiment of an environmentally friendly artificial turf mat according to the present invention.
Referring to FIG. 1, the eco-friendly artificial turf mat according to the present invention may include a green paper, a synthetic turf pile woven on a green paper, and a synthetic turf back coating coated on the green paper .
The artificial turf back coating according to the present invention comprises 100 parts by weight of a polyolefin resin, 1 to 10 parts by weight of nanosilica surface-modified with TEOS (tetraethoxysilane), 1 to 10 parts by weight of a metal oxide powder, 0.5 to 5 parts by weight.
The polyolefin-based resin may be used alone or in combination of 10 to 30% by weight of polypropylene with respect to polyethylene. The polyolefin-based resin may be advantageous in that the adhesive strength and the modulus of elasticity can be increased If the content is less than 10% by weight, the above-mentioned effects are unlikely to be achieved. When the content is more than 30% by weight, characteristics inherent to polyethylenes such as acid resistance, alkali resistance, chemical resistance and impact resistance may deteriorate. .
The nanosilica surface-modified with TEOS (Tetraethoxysilane) imparts properties such as hydrophobicity and water resistance to prevent property deterioration even after long-term use. In addition to improving the pulling force by maximizing the adhesion of the polyolefin resin, Thereby contributing to the improvement of the physical properties.
The nanosilica surface-modified with TEOS (tetraethoxysilane) may be prepared by mixing 10 to 30 parts by weight of TEOS (tetraethoxysilane) based on 100 parts by weight of nano silica having an average particle diameter of 10 to 100 nm.
The metal oxide powder may be at least one of WO 3 , Cu 2 O, CuO, FeO, CoO, ZrO 2 , Sc 2 O 3 and TiO 2 having a micro average particle diameter of 10 to 100 μm.
The metal oxide powder improves abrasion resistance, and TiO 2 , WO 3 Etc. also act as a photocatalyst.
If the content of the metal oxide powder is less than 1 part by weight, it is difficult to carry out the above-mentioned action if the content is less than 0.1 part by weight. If it exceeds 10 parts by weight, it is preferable to restrict the above range.
The bismuth (Bi) -based catalyst serves to shorten the curing time of the artificial turf back coating composition and improve physical properties such as water resistance and abrasion resistance, and it is expected that the above-mentioned effect can be expected by containing at least 0.5 part by weight. Even if it exceeds the weight part, the increase in the above-mentioned effect is insignificant, which is inefficient.
The bismuth (Bi) based catalyst may be a mixture of bismuth (Bi) and Bi 2 O 3 in a weight ratio of 1: 0.1 to 0.3.
When bismuth is used together with Bi 2 O 3 having an average particle size of 10 to 100 nm, a synergistic effect for shortening the curing time can be expected. In addition, since it also acts to block ultraviolet rays or radiation, It is possible to prevent deterioration of physical properties such as adhesion of back coating by ultraviolet rays.
When the content of Bi 2 O 3 is less than 0.1 wt%, it is difficult to expect the effect of lowering the physical properties described above. If it exceeds 0.3 wt%, the catalytic activity due to bismuth may be lowered. .
The nano-sized Bi 2 O 3 The powder can be prepared by reducing a metal precursor in a liquid phase using a reducing agent.
The metal precursor may be a metal hydride, a metal hydroxide, a metal sulfide, a metal nitrate, a metal nitride, a metal halide, a metal alkyl A metal aryl compound, a coordination compound thereof, or a combination thereof, and the metal precursor raw material is bismuth (Bi).
The reducing agent is sodium hydroxide (NaOH 2), lithium view it hydride (LiBH 4), sodium view it hydride (NaBH 4), potassium view it hydride (KBH 4), lithium aluminum hydride (LiAlH 4), sodium Aluminum hydride (NaAlH 4 ), potassium aluminum hydride (KAlH 4 ), or a combination thereof.
The eco-friendly turf back coating composition of the present invention may further comprise a antifouling agent, which is preferably a fluoride selected from among fluoroacrylate, methacrylate, and ethylene fluoride.
The fluoride has a small attractive force between molecules and a low surface energy, so that not only antifouling property but also water repellency and oiling effect can be expected.
The fluoride may be added in an amount of 0.5 to 5 parts by weight based on 100 parts by weight of the polyolefin-based resin.
On the other hand, the artificial grass back coating composition of the present invention can maintain excellent adhesive performance even when coated with artificial turf base paper in a small amount of 250 to 450 g / m < 2 >
Hereinafter, a method for producing a synthetic grass back coating composition according to the present invention will be described in detail.
25 parts by weight of tetraethoxysilane (TEOS) was mixed with 100 parts by weight of nano silica having an average particle diameter of 12 nm and reacted for 3 hours to prepare surface modified nanosilica. Here, the nano silica was Arosil 200 produced by Degussa. Then, acetic acid was added to TEOS (tetraethoxysilane) and hydrolyzed with stirring.
Next, 80 parts by weight of polyethylene, 20 parts by weight of polypropylene, 2 parts by weight of surface-modified nanosilica and 0.5 parts by weight of 5-methoxypentyloxy acetic acid as a dispersant are added to the reactor .
Next, while the reactor was heated to 65 ° C, 2 parts by weight of titanium dioxide, 3 parts by weight of metal oxide powder consisting of 1 part by weight of tungsten trioxide, and 0.9 part by weight of a Bi powder catalyst were added with nano-Bi 2 O 3 , The Bi powder catalyst and the nano-Bi 2 O 3 powder were mixed at a weight ratio of 1: 0.1-0.3 and stirred for 30 minutes to complete the artificial turf back coating composition. Here, nano Bi 2 O 3 is prepared by using Bi (OH) 3 as a precursor and sodium hydroxide (NaOH 2 ) as a reducing agent, and has an average particle diameter of 25 nm.
[Comparative Example 1]
A synthetic turf back coating composition was prepared in the same manner except that the surface modified nanosilica and Bi powder catalyst were not added in Example 1 above.
[Experimental Example 1]
The back coating composition prepared in Example 1 to Comparative Example 1 was applied to the back surface of the base fabric with a spray gun in an amount of 450 g / m < 2 >, and the pulling force was measured in a fully cured state. Respectively. Here, the pulling force of the artificial turf after back coating is tested according to KS K ISO 4919 KS K 0818.
As described above, it can be seen that the back coating composition according to the present embodiment greatly contributes to the pulling power of artificial turf.
The embodiments and the accompanying drawings described in the present specification are merely illustrative of some of the technical ideas included in the present invention. Therefore, it is to be understood that the embodiments disclosed herein are not for purposes of limiting the technical idea of the present invention, but are intended to be illustrative, and thus the scope of the technical idea of the present invention is not limited by these embodiments.
