Common artificial turf

An aggregate layer 30 made of aggregate is formed on the ground 40 and natural rubber, styrenebutadiene rubber (SBR), isobutylene isoprene rubber (IIR), and nitrile butadiene rubber (NBR) ), EPDM (ethylene propylene terpolymers), a vulcanized rubber rubber chip 21 of urethane, and a resin adhesive 22 such as a polyurethane resin or an epoxy resin, and the elastic layer 20 The artificial turf layer 10 in which the vulcanized rubber chips 12 and the silica sand 13 are filled between the artificial turf piles 11 in a state in which a large number of artificial turf piles 11 are planted on the floor mat 14 .

Such artificial turf is filled with a rubber chip such as a vulcanized rubber chip having a size of 2 to 3 mm which cushions the user so as not to be hurt when the user falls down.

Conventional rubber chips for artificial turf filling have a problem that the rubber odor is very bad in artificial turf when rubber chips are filled in artificial turf since vulcanized rubber chips are used or reclaimed rubber chips obtained from waste tires are mainly used Further, when the waste tire recycling rubber chip is used, there is a problem that the smell of waste tire is produced in artificial turf.

Accordingly, in order to solve the above problems, the present invention provides a process for producing a coke oven, comprising 23 wt% of SEBS, 10 wt% of EVA, 54 wt% of calcium carbonate, 3 wt% of coffee sludge, By weight, 0.5% by weight of wax, 5% by weight of white oil, and 0.5% by weight of pigment.

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

The present invention relates to an SEBS rubber chip packed in artificial turf piles planted in artificial turf layers.

The present invention

23 wt% of SEBS (Styrene Ethylene Butadiene Styrene) material, 10 wt% of ethylene vinyl acetate copolymer (EVA), 54 wt% of calcium carbonate, 3 wt% of coffee sludge, 3 wt% of coke powder, By weight, 0.5% by weight of wax, 5% by weight of white oil, and 0.5% by weight of pigment.

.

The main material of the synthetic rubber-filled SBS (SEBS) rubber chip of the present invention is

23 wt% of SEBS as a thermoplastic synthetic rubber, 10 wt% of EVA as a synthetic resin, 54 wt% of calcium carbonate, 3 wt% of coffee sludge used as a reducing agent, and cork powder 3% by weight of stearic acid, 1% by weight of stearic acid used as a softener, 0.5% by weight of wax used as an ultraviolet screening agent, 5% by weight of white oil used as a softener, and 0.5% by weight of a pigment as a colorant.

The coffee sludge is preferably collected by collecting waste coffee sludge used in a coffee shop and then placed in an oven drier for heating and drying.

When the coffee sludge is added, the scent of the scallop escapes from the finished rubber chip, so that the rubber smell is not generated and the odor is not generated by the deodorizing function of the coffee sludge.

Further, since the coffee sludge has its own strength, the finished rubber chip has elasticity and predetermined strength.

The cork powder is crushed to a size of about 0.1 to 0.5 mm, and when the cork powder is introduced, the elasticity of the SEBS rubber chip is increased due to the self-elasticity of the cork powder.

Hereinafter, a manufacturing process of an artificial grass embedding (SEBS) rubber chip of the present invention will be described.

* First Step *

The first step is to prepare and prepare materials for the manufacture of SEBS rubber chips.

That is, as described above,

23 wt% of SEBS material, 10 wt% of EVA, 54 wt% of calcium carbonate, 3 wt% of coffee sludge, 3 wt% of cork powder, 1 wt% of stearic acid, 0.5 wt% of wax, By weight, and 0.5% by weight of pigment.

* Step 2 *

The second step is the work step of mixing the improved materials.

Mixing of materials progresses sequentially through the second order.

Approximately 15 minutes after the first mixing, the SEBS material, EVA, 1/2 of improved calcium carbonate, coffee sludge, cork powder, stearic acid, wax, white oil and pigment are added to the mixer Lt; / RTI >

After the first mixing, the remaining calcium carbonate 1/2 is added to the mixer and mixed for another 5 minutes to ensure that all materials are well mixed.

* Step 3 *

The third step is a step of extruding the extruded material into an extruder.

The extrudate extruded from the extruder is preferably formed in a bar shape having a thickness of 2 to 2.5 mm.

* Step 4 *

The fourth step is a step of cutting the extrudate extruded from the extruder to a size of 2.5 mm in water.

The extrusion is cut in water using a rotary cutter.

A rubber chip for filling having a size of 2 to 2.5 mm is formed through the cutting process.

* Step 5 *

In the fifth step, the rubber chips cut in the fourth step are put in a dehydrator and dewatered to remove moisture, and the water-removed rubber chips are dried while being cooled in a room temperature environment to form a rubber chip (filling chip) of SEBS To complete the manufacture.

Figure 3 illustrates the shape of the finished SEBS rubber chip.

" 모양으로 형성할 수도 있다.The shape of the rubber chip 1 may be formed into a four-leaf crover shape as shown in Fig. 3 (a)

Quot; shape.

As shown in FIG. 3A, when the four-leaf clover is formed, grooves 1a are formed in the spaces between the leaves, so that moisture can be stored in the grooves 1a and light can be absorbed, It is possible to provide the elasticity in the leaf part, the shock absorbing property is good, and the mutual binding force between the chip and the chip can be expected to be increased when the synthetic grass file is filled.

" 모양으로 고무칩(1)을 형성하게되면, 고무칩(1)의 외주연에 복수의 탄성날개부(1c)를 갖고, 탄성날개부(1c)의 내측으로 홀(1b)을 구비하게 되는 구조를 갖게되는 것이며, 홀(1b)에 의해 고무칩(1)이 많은 양의 수분을 저장할 수 있게되고, 복수의 탄성날개부(1c)에 의해 고무칩의 충격흡수성이 향상되며, 인조잔디파일에 충진되었을때 칩과칩의 상호 결속력이 증대되는 효과를 기대할 수 있게된다.
On the other hand, as shown in FIG. 3B,

The rubber chip 1 has a plurality of elastic wings 1c on the outer circumference of the rubber chip 1 and the holes 1b are provided inside the elastic wings 1c So that the rubber chip 1 can store a large amount of water by the holes 1b and the shock absorbing property of the rubber chip is improved by the plurality of elastic wings 1c, It is expected that the mutual bonding force between the chip and the chip is increased.

Since the SEBS rubber chips manufactured as described above contain coffee sludge, the coffee sludge can be expected to have an overall effect of oozing out coffee aroma. In addition, since the odor is removed by the deodorizing function of the coffee sludge The effect can be expected.

In addition, by manufacturing the SEBS rubber chip using coffee sludge as a municipal waste, it is eco-friendly and can be expected to recycle resources.

As the cork powder is added, the resulting SEBS rubber chip is expected to have an increased elasticity while being light in weight compared with the rubber chips of the prior art.

The SEBS rubber chips prepared as described above are filled in between artificial turf piles of artificial turf.
