Description

MAT FOR GOLF PRACTICE AND MANUFACTURING METHOD FOR THEREOF}

The present invention relates to a golf practice mat and a method for manufacturing the same, in particular, by using a thermal process in manufacturing the mat, golf practice mat that can provide a rough practice environment by preventing the hardening of artificial turf and It relates to a manufacturing method.

In general, golf practice mats in the manufacture of artificial turf, planting a yarn such as nylon in a wide fabric using a weaving machine, and fixed by bonding the back of the yarn. At this time, a heat treatment is performed to perform the bonding operation, and the artificial turf, which is a nylon yarn, is cured by the applied heat.

When the golf practice mat using the hardened artificial turf put the golf ball on the artificial turf, the portion where the golf ball comes out on the turf by the hardened artificial turf increases. This provides only a general golf practice environment, there is a problem that you can not practice the rough environment that can occur in the actual field, such a conventional golf practice mat manufacturing method with reference to Republic of Korea Patent Publication No. 10-349436 It will be described in detail as follows.

1 is a plan view and a cross-sectional view of a conventional practice mat for golf, as shown in the first, in the first step of the mat 30 is mixed with a foaming agent and filler to any one of natural rubber, synthetic rubber, synthetic resin . Of course, it is also possible to use silicone rubber or waste tire rubber. Depending on the thickness of the product, the process standards for different mold height, vulcanization time and service time are determined.

Next, in a state in which the buffer sheet 35 and the artificial grass 15 are sequentially stacked on the upper surface of the mat 30 in the second step, the mat 30 is foamed at the same time as the foaming in the press mold. At this time, in the second step, the temperature of the press die is maintained at 120 to 170 ° C. and a pressure of 10 to 100 kg / cm 2. The mat 30 forms a foam layer 30a amplified by 80 to 120% of the thickness before foaming and is formed into a symmetrical shape of 6 to 10 angles.

The cushioning sheet 35 and the mat 30 are made of the same rubber material, but the buffer sheet 35 is preferably maintained at a lower hardness than the mat 30. When the artificial turf 15 and the mat 30 are thermally bonded, the operating temperature is set to 120 to 170 ° C and the press pressure is related to the height of the material within the range of 10 to 100 kg / cm 2. Since the pressure is applied using the heated mold and the press, the artificial grass 15, the cushioning sheet 35, and the mat 30 are integrally bonded to each other, and at the same time, the mat 30 is foamed into a sponge to reduce the weight.

In the manufacturing process using the cooling device is a process of mixing the raw materials as heat and injecting the mold in a liquid or semi-liquid state at this time the temperature of the mold is approximately 10 -20% lower than the mixing temperature. The cooling device has a function of protecting the artificial turf 15 as a configuration in which cooling water flows in the upper plate and a heater is installed in the lower plate.

The extent to which the blowing agent and filler are mixed in the natural rubber, synthetic rubber, and synthetic resin, and the foaming temperature and pressure, depending on the product specification. Set the pressure and vulcanization time according to the height of the product.

If the mat 30 is too low than the appropriate foaming degree of 100 to 200% of the foam layer (30a), the hardness is light, if too large, the elastic force is lowered. The height of the artificial turf 15 is 17 mm, and the overall thickness of the mat is about 10-20 tons. The wearability of the artificial turf 15 conforms to the KSK0818 standard and takes the range specified for the sponge of natural rubber, synthetic rubber and synthetic resin.

Such artificial turf mats have the same or slightly larger dimensions as conventional mats, in which the putt and at-bats are integrated. Since the integrated structure in which the putting mat 10 and the turn at bat plate 20 are not separated as in the related art does not move when in use, damage is less at the time of putting and in particular, there is little elbow, thereby satisfying the quality required in developed countries such as the United States and Japan.

Here, since the mat 30 can be used while being rotated at each corner (that is, eight times) by making one set of four to ten angles, preferably eight octagons, the effect of cost reduction is more than twice in terms of cost reduction compared to conventional golf mats. And more than twice the durability in terms of breakage is guaranteed.

Thus, by the configuration of the octagonal artificial turfstone mat / putting mat integral type manufactured using rubber powder, the appropriate hardness is maintained in the cushioning sheet 35 and the appropriate cushion is maintained in the foam layer 30a of the mat 30 It can provide the same sensation as putting practice on natural grass in the field.

2 is a cross-sectional view of a golf ball placed on the conventional golf practice mat, as shown in the artificial turf 15 is cured by a thermal process, the golf ball is mostly to the upper side of the artificial turf 15 Is exposed.

This provides a fairway environment, which is a common environment in the real field, and cannot provide a rough environment.

There is a need to practice hitting methods such as chip shots in such a rough environment, and there is no practice mat to provide a rough environment.

As described above, in the conventional golf practice mat and its manufacturing method, when the artificial turf is cured using the thermal process in each process to raise the golf ball, most of the golf balls are exposed on the turf, thereby preparing for the rough environment. There was a problem that can not practice one shot.

The present invention in view of the above problems is to provide a rough environment to provide a golf practice mat and a manufacturing method that the user can practice a variety of shots.

The present invention for achieving the above object is characterized in that it is configured to be manufactured at room temperature without using a thermal process.

In addition, the invention is characterized in that it is configured to provide longer artificial turf.

Embodiments of the present invention configured as described above will be described in detail with reference to the accompanying drawings.

3A to 3C are cross-sectional views of the manufacturing process of the golf practice mat according to the present invention. As shown in FIG. Forming (FIG. 3A); Bonding the back surface of the buffer sheet 40 on which the artificial turf 50 is located at room temperature, and then drying at room temperature to form a bonding layer 60 to bond the artificial turf 50 and the buffer sheet 40 to each other. (FIG. 3B); Bonding the mat 70, which is a natural rubber plate or latex plate on the back of the bonding layer 60 at room temperature, and drying and fixing it at room temperature (Fig. 3c).

Hereinafter, the configuration of the present invention as described above and the effects derived from the configuration will be described in more detail.

First, a nylon yarn or a polypropylene yarn is inserted into the buffer sheet 40 using the weaving machine as shown in FIG. 3A.

Since the weaving machine is used, the front and rear surfaces of the cushioning sheet 40 are alternately inserted into the needles as if sewing is continuously performed, and the yarns are continuously inserted in the row direction without interruption.

Then, the ends of the yarns protruding from the cushioning sheet are cut out to separate the yarns inserted in succession into two perforations in one row.

In this case, the yarn exposed to the surface of the buffer sheet 40 is woven so that a plurality of yarns can be exposed in one perforation, and after cutting the end of the yarn, the surface of the buffer sheet 40 has a yarn of 30 to 35 mm. Allow exposure to length.

In this state, the artificial turf 50 is easily removed from the buffer sheet 40, and the artificial turf 50 and the buffer sheet 40 need to be bonded.

Next, as shown in FIG. 3B, a liquid adhesive is applied to the bottom surface of the buffer sheet 40 in which the other side of the artificial turf 50 inserted into the adjacent hole and the other side of the artificial turf 50 are connected to each other. do.

Thus, the process of applying the adhesive is made at room temperature, the process of drying the adhesive after applying the adhesive is also performed at room temperature.

When the adhesive is dried at room temperature, a bonding layer 60 is formed, and the artificial grass 50 is not easily released from the buffer sheet 40 by the bonding layer 60.

As described above, the artificial turf 50 is not cured because the bonding and drying process is performed at room temperature, unlike the related art. Conventionally, the artificial grass is protected by hardening by providing a cooling device, but hardening of the artificial grass cannot be avoided because the hardening of the artificial grass cannot be protected by only the cooling water in the heating process.

Next, as shown in FIG. 3c, the mat 70, which is a natural rubber or latex plate, is adhered to the bottom of the bonding layer 60 by using an adhesive and dried to give an appropriate cushion to the golf practice mat.

In forming the mat 70 as described above, the mat 70 can be formed by eliminating the thermal process by using a plate-like material without using rubber powder or the like.

In other words, in the prior art, it was a form in which a mixed material such as rubber powder was pressed by applying heat, but in the present invention, by bonding the already completed plate-shaped natural rubber or latex with an adhesive, the thermal process is omitted to cure artificial grass. It can be prevented.

The process of adhering and drying the mat 70 is also performed at room temperature, thereby allowing the artificial turf 50 to manufacture a golf practice mat in an uncured state.

Since the artificial turf 50 is not hardened, the hardness of the artificial turf 50 is lowered, so that the artificial turf 50 is easily bent as compared to the conventional artificial turf.

In addition, the surface of the mat 70 in contact with the floor is formed with a non-slip structure, such as a plurality of bones, a plurality of irregularities or a plurality of protrusions in the direction perpendicular to the direction to shoot using the golf practice mat.

Such an anti-slip structure prevents the mat 70 from slipping even when the user applies a force to the leg to take a shot, thereby preventing slipping while using a light mat.

4 is a cross-sectional view of a golf ball placed on top of a golf practice mat manufactured according to the present invention golf practice mat and its manufacturing method, as shown in the artificial turf 50 is not cured, its length Is about 30 mm longer than the conventional one, so that about half of the golf ball 80 is buried in the artificial turf 50.

The characteristic of such a state is that the state where the golf ball 80 is buried in the artificial turf 50 is intensified, so that it is possible to provide a user with an environment that can practice shots such as chip shots in the rough.

As described above, the present invention prevents hardening of the artificial turf so that the artificial turf can be easily bent, thereby enabling the shot to be prepared for a rough environment.

In particular, by forming the length of the artificial turf to about 30mm, to provide a rough environment that is not easy to shot, there is an effect that the user can develop an adaptability to the rough environment in the actual field.
