The present invention relates to an artificial turf structure and a method for manufacturing the same, and more particularly, to an artificial turf structure and a method of manufacturing the structural improvement of the adhesive strength to the construction surface.

Artificial turf is made of synthetic fiber material in the form of grass, and is widely used in various stadiums and various indoor interior materials such as a baseball field or a soccer field due to the advantages of easy management after construction and always greenness.

As shown in FIG. 1, a general artificial turf includes an artificial turf structure 101 forming an artificial grass shape, and a filler (not shown) filled in pile yarns of an artificial turf structure to be described later.

Among them, the artificial turf structure 101 is formed on the bubble layer 110, the pile yarn 120 gathered on the bubble layer 110, and the bottom surface of the bubble layer 110, and the pile yarn 120 is in the state of being raised. It is composed of a support layer 130 bonded to the construction surface while maintaining a firm.

The artificial turf structure 101 is piled on the sheet forming the bubble layer 110 by tufting the pile yarns 120, and forms the support layer 130 on the lower surface of the sheet opposite to the pile yarn 120. It is manufactured by the process.

Meanwhile, in recent years, in consideration of the recycling of the artificial turf structure 101 according to the recent trend of receiving environmentally friendly products, a technology in which the bubble layer 110, the pile yarn 120, and the support layer 130 are made of the same synthetic fiber material is described. It was developed.

As an example, recently, the foam layer 110, the pile yarn 120, and the support layer 130 are formed using polyolefin-based synthetic fibers, which are advantageous for reducing friction, as the material of the artificial turf structure 101. After going through a simple artificial turf recovery process to separate only the filler, it was possible to easily recycle the recovered artificial turf structure (101).

However, in the conventional artificial turf structure made of such a polyolefin material, since the polyolefin material is a chemically very stable structure, there is a disadvantage in that the adhesive strength is not maintained strongly even when the adhesive material is applied to the support layer and adhered to the construction surface. . As a result, the quality of artificial turf construction is significantly reduced, and maintenance occurs frequently after the construction of artificial turf, which causes a problem of economic loss.

And a semi-finished product supplying step of supplying a semi-finished product of the artificial turf structure in which pile yarns are incorporated into the bubble layer, a support layer forming step of forming a support layer on the bottom surface of the bubble layer of the semi-finished product, and forming an adhesion strengthening pattern on the bottom surface of the support layer. It is also achieved by a method for producing an artificial turf structure comprising the step of forming an adhesion strengthening pattern.

Here, it is preferable that the step of forming the adhesion strengthening pattern is a step of forming a scratch on the lower surface of the support layer.

At this time, the step of forming the adhesive force strengthening pattern is effective to form the scratch by a high frequency corona treatment.

The bubble layer, the pile yarn, and the support layer are more preferably formed of a polyolefin material.

On the other hand, at the support layer forming step, it is more effective to provide at least one heating roller for heat-sealing the support layer on the bottom surface of the bubble layer of the semi-finished product.

In this case, the heating roller is a first heating roller for melting the lower surface pile yarn of the bubble layer, a second heating roller for heat-sealing the bubble layer and the support layer, and a bubble layer heat-sealed in the second heating roller It is preferable to have a 3rd heating roller which heat-fuses a support layer again.

At this time, it is more effective that the non-adhesive material is coated on the surface of the heating roller.

2 is a partial cross-sectional view of the artificial turf structure according to the present invention;
Figure 3 is a block diagram of the manufacturing process of artificial turf structure according to the present invention.
Figure 4 is a manufacturing process of the artificial turf structure according to the present invention.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

As shown in FIG. 2, the artificial turf structure 1 according to the present invention includes a bubble layer 10, a pile yarn 20 forming a grass layer on the bubble layer 10, and a bubble layer 10. It is attached to the lower surface includes a support layer 30 that is adhered to the construction surface while firmly supporting the pile yarn (20).

The bubble layer 10 serves to impart morphological stability of the artificial turf structure 1 and firmly seat and fix the pile yarn 20. The bubble layer 10 is formed of a woven or nonwoven fabric of a polyolefin fiber, or a woven or nonwoven fabric of a polyolefin fiber. And it may be provided in the form including a web of polyester short fibers or polyolefin short fibers on the lower surface.

The pile yarn 20 serves to give the artificial turf structure 1 a characteristic similar to that of natural grass, and is formed by incorporating a polyolefin yarn on the bubble layer 10. More specifically, in the method of attracting the yarn, a tufting method of forming a loop pile of a predetermined shape by tufting a polyolefin yarn on the bubble layer 10, a mocket method or a Raschel method of simultaneously forming the bubble layer 10 and the pile. Etc.

The support layer 30 serves to enhance the shape stability of the artificial turf structure 1, reduce noise, strengthen tear strength, and strengthen the pull strength of the pile, and is formed by coating a polyolefin resin on the lower surface of the bubble layer 10. More specifically, the polyolefin resin film is engaged with the lower surface of the bubble layer 10 and then coated through a heating and pressing process. Since the olefin-based material constituting the support layer 30 is a relatively economical material, it is possible to reduce the cost of the artificial turf structure 1 and is the same material as the bubble layer 10 so that it is strongly bonded to the bubble layer 10 and piled up. The pullout strength of (20) can be improved. In this case, the polyolefin forming the support layer 30 preferably has a lower melting point than the polyolefin forming the bubble layer 10. Changes in physical properties of the bubble layer 10 may be minimized during the formation of the support layer 30.

On the other hand, when the artificial turf structure 1 is bonded to the construction surface by using an adhesive material on the lower surface of the artificial grass structure 1 according to the present invention, an adhesion strengthening pattern 31 for maximizing adhesion strength ) Is formed.

It is preferable that this adhesive force strengthening pattern 31 is a fine scratch. The scratch may be formed by heating and compressing a polyolefin resin film on the bottom surface of the bubble layer 10 to form the support layer 30, and then applying a high frequency corona treatment to the bottom surface of the support layer 30. Of course, the adhesive force strengthening pattern 31 may be a scratch by mechanical processing or a similar pattern in addition to the fine scratch by high frequency corona treatment.

 The adhesive force strengthening pattern 31 eliminates the decrease in adhesive force of the adhesive material due to the chemically stable structure of the polyolefin resin film forming the support layer 30, and maximizes the penetration of the adhesive material into the lower surface of the support layer 30.
