Description

Tea mat without tee holder and its manufacturing method {THE MAT WITHOUT TEE HOLE AND THE METHOD OF PREPARING IT'S TEE-MAT}

1A-1C are perspective views of a conventional tee-mat

2 is a perspective view of a tee mat without a tee rack according to the present invention;

The present invention relates to a tee mat without a tee holder and a manufacturing method thereof. Specifically, a tee mat that can be easily inserted into a tee without a tee hole or a cutting line for teeing a tee on a tee mat, and It is about the manufacturing method

In the early days, as a tee mat configured to insert a tee as a conventional technology, rubber tires (1) were formed by cutting waste tires in the circumferential direction as shown in FIG. There is tea mat (A)

Such a rubber tee mat is used by inserting a tee (3) between adjacent rubber bells (1). When the driver or the iron head has a strong impact and friction with the rubber belt during the blow, a large shock occurs in the wrist. In addition, the elbow may be impacted, and the rubber is attached to the sole part of the screwdriver or the iron head, which is heavily contaminated and difficult to remove.

As a prior art developed in the next step, the tea mat is bonded to the base fabric 2 of the artificial turf 1 with the adhesive 4 to the rubber plate 3 as shown in FIG. A tee mat is formed by drilling a circular hole (5) and then inserting and fixing a rubber column (7) having a cross cutting line (6). The tee (8) is to be plugged, but if you break the tee when hitting a broken tee without being uncomfortable to insert the tee, but now rarely used.

In addition, the most frequently used tea mat as shown in Figure 1c as the upper layer is artificial turf (1) layer and the base fabric (2) to bind the artificial turf layer to press the unvulcanized rubber plate (3) by pressing the unvulcanized rubber sheet (3) is embedded in the net fabric of the base fabric (2) and vulcanized in the embedded state and the soft rubber sponge or urethane sponge layer (4) is bonded to the vulcanized rubber plate (3) and the bottom rubber plate ( 5) adhesively laminated to form a tee mat, and together with the base fabric of the artificial turf layer, the rubber sheet 3 and the sponge layer 4 are cut in the longitudinal direction of the tee mat to form a plurality of tee stand cutting lines 6 Tea mat.

In the early stage of use, the tee stand cutting line (6) is hidden from the artificial turf, so it is difficult for the PLAYER to find the cutting line and insert the tee. If you put the ball up and put the ball on the tee, the tee will fall frequently, causing a great inconvenience, and the longer you use it, the more the two compartments separated by the tee rack cutting line are detached and become unusable. .

The present invention is a tee mat that solves the problem of the tee rack formed in the conventional tee mat of various types, instead of a hard thick rubber plate laminated to a soft thin rubber plate directly below the artificial dandy layer to adhere to a sponge or foam You can easily insert a tee anywhere on the artificial turf layer without constructing a tee rack on the artificial turf layer, and also reduce the shock transmitted from the artificial turf mat when hitting, so that you do not receive excessive shock on the wrists and elbows. Rather, it provides a tea mat and a manufacturing method thereof without a tee rack to reduce expensive rubber raw materials.

A tea mat without a tee holder for achieving the present invention is formed of monofilament extruded from thermoplastic resin such as nylon (polyamide), polyester resin, polypupopyrene resin, and freat yarn (FLAT YARN) as shown in FIG. Artificial grass brushing layer (1), binding fabric (2-3), which is embedded in the soft rubber layer (3), the base fabric (2) in which artificial grass is planted and fixed, the thin film soft rubber layer (3), foam layer (4), It can be said that the tee mat without the tee stand part laminated | stacked in the order of the bottom rubber layer 5 is called.

In addition, the manufacturing method of the tea mat will be described as follows.

A one-step process of mixing and kneading 7-10 wt% of a softener to an unvulcanized rubber to which natural or synthetic rubber is added an additive including a conventional vulcanizing agent;

The two-step process of extruding the soft rubber composition subjected to the one-step process to a sheet of 1.5mm ~ 2mm thickness and laminated on the foamed EVA sheet of 2-3cm thickness and

A three step process of joining artificial turf ground fabric to a layer of soft rubber composition laminated on the foam sheet which has passed the two step process and passing it through several pressure rollers to partially vulcanize it;

It is a method of manufacturing a tea mat having a tee stand portion comprising a four-step process of bonding the low-foamed foam sheet and the bottom rubber plate of the laminate having a three-step process, cut to a predetermined standard and vulcanized at the same time curing.

Here, some vulcanization of the three-step process is to maintain the form of the composition layer while partially vulcanizing the soft rubber composition layer so that there is no problem in operation.In this process, it is partially vulcanized after passing the heat chamber for about 10 minutes. In the process, the foam layer and the bottom rubber are adhered with an adhesive, so that the curing of the adhesive after cutting and the complete vulcanization of the partially vulcanized soft rubber composition layer, and if the bottom rubber plate is an unvulcanized rubber plate, are performed to obtain the complete vulcanization thereof When put into a vulcanization chamber (hardening chamber in the city) maintained at 120 ~ 150 ℃, the vulcanization, curing action is completed naturally.

In the manufacturing method, the soft rubber composition is a composition having plasticity having the same viscosity as the dough, and is easily extruded as an extruder or passed through an interlocking roller of the kneader to obtain a thin sheet of 1.5 to 2 mm. In addition, the EVA foam sheet has a foaming ratio of 3 to 5 times, and when the foaming ratio is higher, the bearing capacity is weak, which is a problem when the artificial turf is laminated. As the finished tea mat is used, the thickness of the tea mat is gradually reduced and the foaming ratio is increased. If it is less than three times, the tee coming through the soft rubber layer is not easily inserted. When the soft rubber composition layer is formed on the EVA foam sheet, the base fabric of the artificial turf layer is bonded and pressurized thereon, and the net fabric of the base fabric is softly embedded in the soft rubber composition layer, and the EVA is down. The soft rubber composition is embedded in the numerous pore layers of the foam layer and is vulcanized in this state, so the binding effect is increased by interlocking. In the case of the foam sheet which can be used but the adhesion is not good, the adhesive may be first coated on the foam sheet, a soft rubber composition layer may be formed, and then pressurized as described above.

In addition, the softeners added to the conventional blended rubber raw materials include vegetable oil softeners such as fatty acids and fatty oils, pine oils such as pine oil, pine oil, tall oil, fat oil, and aromatic oils. Petroleum, naphthenic oil, paraffinic oils, petroleum, dehydration, collal softeners such as Kumaron indene resin, and synthetic softeners. Mold softeners, when added in excess, act as a solvent, dominating the fluidity of the polymer and failing to maintain a given form.

And the thickness of the soft rubber composition layer must be limited If the vulcanized in a thick state of more than 2mm is not easy to insert the tee, If the thickness is less than 1.5mm Of course, artificial turf layer and floor fabric is laminated on the upper layer However, the vulcanized soft rubber layer can be broken by the impact of the drive or iron head.

In addition, the thickness of the foam layer is also limited. The height of the artificial grass layer raised from the upper layer is 1 ~ 1.5cm, the thickness of the soft rubber layer is 2mm, and the foam layer is 2.5cm ~ 3cm. The maximum depth of 3.7cm is 4.7cm, which allows the longest tee to be plugged into this range. To insert the tee, the tip of the tee passes through a 1-1.5 cm artificial turf layer and passes through a binding layer and a soft rubber layer mixed with a 1.5-2 mm soft rubber layer and a base fabric, and is inserted into a foam layer having a thickness of 2.5-3 cm. Does not proceed due to the hard floor rubber plates. Therefore, if the thickness of the foam layer is too low, the tee cannot be inserted to the proper height.

The tea mat manufactured by the above method can be easily plugged into the tee anywhere in the artificial turf layer, and the height can be adjusted freely. Like 1c), it is possible to save a large amount of rubber raw materials because it is laminated with thin rubber plates instead of thick rubber plates under the artificial turf layer as well as to prevent impacts from hard rubber plates of conventional tee mats during impact. It is possible to alleviate the impact on the elbow, and also in the manufacturing method, it is possible to combine the substrate material of the artificial turf layer and the soft rubber layer by pressing a weak roller without the pressure and hardening of the high pressure heat press mold. It can prevent the damage of the brushed up and exposed, and also continuous Since it is a method, it can be said that it is a tee mat which does not have a tee stand part which can greatly improve productivity, and its manufacturing method.

As described above, the tea mat according to the present invention can be easily inserted anywhere in the artificial turf layer without having to form a separate tea mat, and the height of the tea can be adjusted and the flexible soft rubber layer and the foam layer under the artificial turf layer. As it is laminated, it is a tee mat that can alleviate the impact on the arm through the shaft when it is hit.It can greatly reduce the cost of rubber materials and the method of manufacturing it, and can prevent the damage of brushing of artificial turf layer and greatly improve the productivity. It can be referred to as a tea mat and a manufacturing method there is no tee holder.
