Abstract

A thin film of the flowable rubber coating layer is formed on the unvulcanized rubber sheet to which the foaming agent is added, and the fabric sheet of the artificial turf layer is bonded thereon and pressed by roller or press to penetrate and bond the thin film of the flexible rubber to the tissue of the artificial grass layer. After the rubber binding layer was formed, the laid nylon monofilament was raised, and then passed through a heat chamber to convert the unvulcanized rubber binding layer of the thin film into the vulcanized thin rubber binding sheet, and the vulcanized rubber sheet containing the foaming agent was vulcanized and low. The foam obtained by forming a low-foam rubber sheet cured by foaming is cut to the size of a tee mat size to form a partial cut line, and then is a tee mat that is bonded to the low-foamed surface in the order of a sponge layer and a rubber sheet. A thin film rubber bonding layer is formed between the layer and the low-foam rubber sheet, so that the separation between the two layers is perfect. Cut the laminated body laminated with artificial turf layer, thin film rubber bonding layer and low foaming rubber sheet layer from above to cut through the partial cutting line in one row in the longitudinal direction, and heat and heat are formed in parallel. Adjacent rows and partial cut lines formed in the rows are formed so as to be staggered with each other, so that the break of the partial cut line (tea flower part) becomes loose and prevents the rupture of the weak sponge layer without the partial cut line in the sponge layer.

Manufacturing method of golf tee mat {THE METHOD OF PREPARING TEE MAT FOR GOLF}

1 is a golf tee mat manufactured by the manufacturing method according to the present invention

Figure 2 is a manufacturing process of the present invention golf tee mat

Figure 3 is a perspective view of a heat cutting machine forming a partial cutting line of the present invention golf tee mat

The present invention relates to a golf tee mat (T-MATT), and more particularly to a method of manufacturing a golf tee mat to drive the tee in the drive shot or iron shot in every first turn at the time of golf rounding. Conventionally, there are various types of tee mats, but conventionally used tee mats are made by cutting waste tires in a circumferential direction to produce a belt having a rectangular cross section, and dozens of belts are connected to the side and stitched together with steel wire (wire) to integrate them. There is a tee mat on the top, and this rubber tee mat puts the tee between the belt and the belt of the mat, puts a golf ball on it and makes a tee shot.

The rubber tee mat as shown above is effective in judging the direction of the batting because the belt direction is placed in the direction in which the batting should fly, but it lacks the homogeneity of the T-mat by using waste products such as waste tires and does not have good aesthetics. In particular, since the viscoelastic coefficient of friction of the rubber itself is large, the moment when the drive or the iron head touches the rubber tee mat has a large resistance, eventually, the distance is reduced, and black rubber is attached to the bottom of the drive or the iron head, which is not easily removed.

Another conventional tee mat is a tee mat bonded to a cotton plate of an artificial turf of an artificial turf in which synthetic fiber yarns such as nylon monofilament yarns are bonded together with a rubber sheet. A part of the upper part is fixed to the groove formed in the tee mat by fixing the circumferential stand cut to a certain length in three or four directions from the center to the reflection image. .

The tea mat as described above has to penetrate the rubber plate and the artificial turf layer to form a tea flower, so if the tee shot is repeated, the damage of the artificial turf will easily come near the tea flower, and the tee shot can be pushed away. Since the tea is easily broken and broken at the time of the blow, the broken tea is embedded in the tea flower, so if you do not pull out the broken tee piece, there is an uncomfortable point in that the tea cannot be reflowered.

And there are artificial turf batters that are made of artificial grass such as nylon monofilament yarn planted on the fabric paper and some of the nylon monofilament yarn with soil or sand, and the nylon monofilament yarn and most of them are raised to give the texture of natural grass. This is a tee shot after raising the ball and making a tee shot, which feels like a natural grass, but the drive or iron head touches the ground, which leads to high wear rate and damage. Lose.

In addition, recently, the nacelle fabric surface of artificial turf, which is composed of a chemical fiber yarn such as nylon monofilament, is bonded to a thick uncured rubber sheet by pressing and vulcanizing it, and then a sponge is adhered under the vulcanized rubber sheet. A tee mat having a plurality of cut lines at regular intervals in the longitudinal direction of the mat from the artificial turf layer to the sponge layer is widely used in a laminate in which a rubber sheet, which is a bottom layer, is bonded under the sponge.

Since the tee mat is cut from the artificial turf layer to the sponge layer in the full length direction of the mat, the tee is easy to flower and the cutting line is oriented in the direction of the effective ball, so the direction can be easily determined and the cutting line is the drive or the iron head. It is almost coincident with the direction of rotation, so it can easily absorb the resistance of the tee when it is blown, and thus has the advantage of preventing the rupture of the tee. Since the rubber sheet layer is extremely hard and the thickness is more than 1cm, the head does not absorb the weight of the head and the direction of rotation when the drive hits the front point (front ground) at the place where the golf ball is placed. The head is inclined to the upper side due to the momentary force at the RBI due to the force of the force. Since bouncing effort to become a stand tapping (Topping) it is reduced is not fit correctly or eventually go the ball rolling distance significantly.

Of course, this is especially true in the case of high-handed fryers and in the case of fryers hitting the ball on the artificial turf without a tee.

Recently, as golf sports have been prominent both at home and abroad, golf products with excellent functionality have been released one after another by conducting competitive research to improve the accuracy and direction of the putter, including the improvement of the drive, iron head, shaft accuracy, and flying distance. .

In parallel, the tee mat is scientifically analyzed to provide a more improved tee mat, and as part of it, the drive or iron sash head front bottom corners can be guided to the bottom of the golf ball as much as possible. By absorbing the instantaneous impact of the impact of the mat hit by the wing (rotation) of the mat, the mat is constructed so that it can be guided directly below the golf ball without significantly changing the direction of rotation. The purpose of the present invention is to provide a manufacturing method of a tea mat that has excellent functionality and durability by preventing damage to the weak sponge layer by preventing the flowers from being cut and the cutting line of the tea flower down to the sponge layer. I will.

The present invention relates to the manufacture of a tea mat that solves the problem of a hard rubber sheet supporting the artificial turf layer while contacting the artificial turf layer in the conventional tea mat, the configuration of such a mat is nylon from above as shown in FIG. Artificial grass layer consisting of monofilament or chemical fiber yarn (1 ') and woven paper (1 ") (1) Thin-film rubber binding sheet layer (2) Low-foam rubber sheet layer (3) Sponge layer (4) Rubber layer The partial cutting lines 6 are laminated in the order of (5) from the artificial turf layer 1, which is the surface layer in the longitudinal direction of the transfer laminate, to the low foaming rubber sheet layer 3, to form several partial cutting lines in a row. Although several rows and rows are formed in parallel, adjacent cut lines 26 formed in adjacent rows and rows may be called golf tee mats formed to be staggered with each other. The manufacturing method of the tee mat is a release paper as shown in FIG. 11) Above A relatively viscous flowable rubber (15) extruded from the extrusion container (14) onto the unvulcanized rubber sheet (12) while transferring the sheet to which the unvulcanized rubber sheet (12) to which foaming agent is added is conveyed to the conveyor belt (13). Fabric paper (19 ") of artificial turf layer (19) formed by roller (16) or knife gotha (16 ') to form a thin film flowable rubber coating layer (17) of constant thickness thereon and which is guided from artificial turf winding roller (18). ) Is bonded and pressurized with pressure rollers 20 and 20 'to penetrate and bind the thin film flowable rubber coating layer 17 to the tissue of the fabric (19 ") to form the thin film rubber binding layer 21, followed by roller brushed brush ( 22, 22 ') to raise the nylon monofilament 19' of the artificial turf layer 19, and pass the heat chamber 23 to pass through the thin film rubber binding layer 21. Hardened or solidified and the vulcanized rubber sheet 12 to which the blowing agent was added At the same time, a low-foaming low-foam rubber sheet 25, which is vulcanized and cured and solidified, thereby laminating the artificial turf layer 19, thin-film rubber binder sheet 24, and low-foam rubber sheet layer 25 from above. And cut it to the size of the tee mat size with the cutter 27 on the die 26, and partially cut it with the hot plate cutter 100 as shown in FIG. 3 to form a partial cut line 28, and then sponge in a conventional manner. When the adhesive layer of the layer 29 and the bottom rubber sheet 30 is laminated, a tea mat according to the present invention is manufactured.

In the above method, instead of forming the thin film flowable rubber coating layer 17 on the unvulcanized rubber sheet layer 12, the semi-solid rubber sheet of the thin film is extruded by a separate extruder and wound around a winding roller in a rolled shape on a double-sided release sheet. When the double-sided release paper is separated and the semi-solid rubber sheet 17 'of the thin film is laminated on the unvulcanized rubber sheet 12 of FIG. 2, the rest of the process is carried out by the same method as that of FIG. Mats may also be produced.

Alternatively, coating a highly viscous flowable rubber on a certain size of the uncured rubber sheet to form a thin film coating layer of fluidity, the fabric paper of artificial turf layer first touch or semi-solid rubber sheet on the uncured rubber sheet After laminating the fabric paper of artificial turf layer to the first touch, press it with press (flat press) and raise nylon monofilament of artificial turf layer with brushed brush, and the vulcanized rubber sheet is vulcanized and low foamed in heat chamber. The thin film flowable rubber binding layer or the semi-solid rubber sheet of the thin film is vulcanized to form the rubber binding layer of the thin film, so that the laminated body laminated from above is made of artificial grass layer, thin film rubber binding layer and low foaming rubber sheet layer (laminated sheet). ) And cut it to a tee mat size with a press cutter to form a partial cutting line, and then use a sponge layer and a bar as usual. By a layer bonded to the rubber sheet is to manufacture a tea mat according to the present invention. However, this method is not continuous work, but the production yield is poor due to the pressure lamination by press per unit tee mat, but in the binding force between the artificial turf layer and the thin film rubber binding layer (thin rubber binding sheet) than the method of FIG. Can be better.

In the above method, the vulcanized rubber sheet is a vulcanizing agent, accelerator, vulcanization accelerator, coloring agent, foaming agent, foaming aid, which are commonly used in natural or synthetic rubber materials, but the foaming ratio is extremely important. Chemically decomposed and gasified substances, ammonium carbonate, sodium bicarbonate, urea, DAB, DPT, BSH sulfonylhydrazide, and azobisisobutylnitrile are optionally added depending on the rubber material. It is possible to control the decomposition temperature of blowing agent such as stearic acid, oreic acid, biratinate, DAB, stearic acid for DPT, salicylic acid, futalic acid, boric acid, urea melanin, ethylene glycol, etc., and the foaming ratio is 0.4 ~ 0.7. Limited and continuous foamed low foams are more preferred. For this reason, it is not able to withstand the breakdown strength due to the weakness of external appearance such as rubber sponge, and if it is less than 0.4, the breakdown strength and the tensile strength are weak, so that the durability decreases, the bursting phenomenon occurs, and the external gravity increases to more than 0.7. Then, when hitting by the drive or swing of the iron head, the mat does not absorb the impact of the head momentarily and the head tends to spring up due to the elasticity, and the head does not reach the bottom of the golf ball. The odds are higher and eventually the distance is reduced. For this reason, the foam should be foamed with low foaming in the range of 4 ~ 0.7 of specific gravity.

In addition, the softening agent is used for the semi-solid rubber sheet of the thin film used in the formation of the rubber thin film binding layer, and the amount of the softener is used in the range of 14 to 18 parts of softener per 100 parts of rubber. If the mineral oil-based softener is used in the range of 18 to 23 parts with respect to 100 parts of rubber, the viscosity can be lowered and the fluidity can be obtained.

Softeners used in the semi-solid rubber sheet described above include fatty acids of stearic acid, lauryl acid and palmitic acid oleic acid, and castor oil with excellent cold resistance, fatty oils such as peanut oil, palm oil and palm oil, which have high plasticizing effect and low pollution, pine oil and rosin ester rubber. Pine tar, tall oil, and plastics, and other derivatives, can be selectively used according to the type of rubber.As a mineral oil softners used in the thin film coating layer of the fluid, It has good compatibility and can be blended in a large amount. It has good dispersibility and better physical properties of rubber than naphthenic naparaffin. It has good compatibility with rubber, good cold resistance, non-pollution and color stability. Naphtherio oil is good and has good oxidation resistance, and it is non-polluting, non-discoloring, resilient and specific rubber. For example, EPM-EPDM-IIR and the like is used to adjust the composition ratio of the mineral oil of the mixture of three combinations of paraffinic oil such as extremely excellent compatibility according to the type of rubber.

Although the purpose of using a large amount of softener is to reduce the viscosity of rubber, the solvability or swellability of the polymer is strong, so that it is solvated uniformly to the polymer molecules and surrounded by a plastic solvated molecular layer. It promotes plastic flow by smoothing the slipperiness of polymers. It is well dispersed in tissues and is a fine colloidal spherical particle in each place of the coagulated structure of polyamide. It has the function of giving lubricity that is considered to give.

Here, plasticizing fluidity is imparted to the flowable rubber coating layer of the thin film forming the rubber thin film binding layer or the semisolid rubber sheet of the thin film. In the conventional tea mat, the artificial turf layer and the rubber sheet are bonded with an adhesive, or the artificial turf layer and the ordinary The most problematic problem is that the artificial turf layer and the vulcanized rubber sheet (hard or semi-rigid rubber sheet) are separated shortly after use of the tee mat which binds the uncured rubber sheet. It provides plastic fluidity to the artificial turf by forming a strong binding ring with the artificial turf layer after vulcanization because the rubber of the flexible rubber coating layer or semisolid rubber sheet easily penetrates into the fiber structure of artificial turf layer when pressurized by roller or press. The purpose of this is to prevent separation from occurring between the layer and the binder rubber sheet layer.

In the laminate constituting the core lamination layer of the tea mat of the present invention, the artificial turf layer is nylon monofilament or synthetic fiber yarn is implanted in a nacelle fabric, and the length of the wefted fiber yarn is about 1.5 cm and is bonded to the artificial turf layer. The thin film rubber bonding layer is around 2mm, the low foaming rubber layer is in the range of 10-15mm, and the sponge layer is in the range of 2cm ~ 3cm and the bottom rubber sheet layer is around 1cm. In addition, the viscosity of the rubber layer before vulcanization is lowered in the order of the unvulcanized rubber sheet, the semi-solid rubber sheet of the thin film, and the flowable rubber coating layer of the thin film.

In addition, as shown in FIG. 3, the cutting lines 102 are formed in parallel with several rows of partial cutting edges 102 in the longitudinal direction on the lower side of the heat transfer plate 101, and the partial cutting blades formed in the adjacent rows and the rows are alternately positioned. The protruding heat cutting machine 100 penetrates the cut laminated body in the order of the artificial turf layer, the thin film rubber bonding layer and the low foaming rubber sheet from the artificial turf layer to form a partial cutting line.

This staggered partial cut line is a problem that occurs in a tea mat in which several cutting lines are formed in a straight line from an artificial turf layer to a sponge layer in the longitudinal direction of a conventional tea mat. By loosening the group and forming a partial cutting line to the sponge layer, it is possible to solve various problems in which the rupture phenomenon occurs even in the sponge layer having a very weak tear strength.

The tee mat according to the present invention has a low-foaming foam sheet that is continuously foamed under the artificial turf layer, and has a shock absorbing function to induce a drive or iron shot yarn from the tee mat to the bottom of the position where the golf ball is placed. Therefore, the golf ball can be hit precisely, preventing the shank or the topping, and thus the flying distance can be improved, and the plastic material and the flowable rubber material between the artificial turf layer and the uncured rubber sheet can be used when manufacturing the tea mat. The thin film rubber binding layer formed by laminating and vulcanizing strongly binds the low-foam rubber sheet and the artificial turf layer, so that it does not detach from the low-foam rubber sheet, so it is excellent in durability, and the partial cutting line is alternated with other rows. The cutting line for tea is formed only from the artificial turf layer to the low-foam rubber sheet layer. No one is going to be called for the preparation of the risk of rupture is not in the sponge layer golf tee mats.
