Description

Bending prevention rubber mat containing a net yarn and a manufacturing method therefor {A RUBBER MAT FOR BENDING PROTECTION COMPRISING NET® FORMED PLASTIC FIBER AND A MANUFACTURING METHOD THEREOF}

The present invention relates to a rubber mat for preventing warpage including plastic mesh yarn and a method for manufacturing the same.

Recently, the interest in health has increased and the number of users of parks and trails is rapidly increasing.

Pedestrians prefer to exhibit excellent cushioning feeling without the occurrence of dust or the like when walking, and thus, a tendency to lay elastic rubber mats and the like on the floor is prominent.

The rubber mat has elasticity to reduce joints when walking, and unlike the general soil floor, there is little occurrence of dust, etc., and thus has excellent characteristics as a flooring material.

However, when the pedestrians step on the mat, the center of the mat is mainly stepped on, so after a certain period of time after installation, the center part of the mat enters and the corner part rises up, which is not only in appearance but also inconvenient to walk. .

The present invention has been made to solve the above problems, the problem to be solved in the present invention is a rubber mat placed on a playground or walkway, etc., even after a certain time is maintained without deformation of the appearance without bending inconvenience bending An object of the present invention is to provide a rubber mat for prevention and a method of manufacturing the same.

In order to solve the above problems,

The present invention provides a method for producing a rubber mat for preventing warpage, characterized in that the polypropylene, polyethylene or PVC net yarn is coated with a urethane solution, and then pressed to the lower portion of the rubber mat.

In addition, the present invention is to put the material corresponding to 85 to 95% of the final thickness of the rubber mat in the mold, and after adding polypropylene, polyethylene or PVC net yarn at the bottom, the remaining thickness of the rubber mat at the bottom of the net yarn added Provided is a method for producing a rubber mat for preventing warpage, characterized in that the molding material is added to 5-15%.

The present invention also provides a rubber mat for preventing warpage produced by the above production method.

When installing the anti-bending rubber mat prepared according to the manufacturing method of the present invention, such as playgrounds and walkways, even if the pedestrian is used for a long time there is an effect that can maintain the mat floor without bending without deformation of the mat appearance.

1 is a picture showing the polyethylene mesh yarn of the present invention,
Figure 2 is an enlarged photograph showing the polyethylene mesh yarn of the present invention.

Hereinafter, the present invention will be described in more detail.

As described above, the present invention provides a method for producing a rubber mat for preventing warpage, characterized in that the polypropylene, polyethylene or PVC mesh yarn is coated with a urethane liquid, and then pressed to the lower portion of the rubber mat.

The net yarn of the present invention is produced using polypropylene, polyethylene or PVC as a raw material.

The manufacturing method of the mesh yarn is not particularly limited, but for example, the method described in Korean Patent Registration No. 10-0536737 can be used.

The thickness and width of the mesh yarns may be properly adjusted according to the use of the floor to be constructed, but the thickness of the mesh yarns is preferably 1 to 3 mm and the grid spacing is 20 to 40 mm.

The net yarn manufactured by twisting or combining twisted yarn as described in the above document is cut according to the size of the rubber mat to be attached and then applied to the next process.

The net yarn of the present invention prepared as described above is coated with a urethane liquid before compression molding on the lower portion of the rubber mat.

When pressing the net yarn directly to the rubber mat without the coating process with such a urethane liquid, there is a problem that the adhesive strength with the rubber mat is weakened.

Therefore, when the net yarn is coated with a urethane liquid and then press-molded on the lower portion of the rubber mat, the net yarn and the rubber mat are completely combined.

As a method of coating with a urethane liquid, for example, the net tissue yarns can be immersed in the urethane solution and then passed through a compactor by rolling so that an appropriate amount of the urethane solution can be buried in the net yarn.

Coated net yarn is attached to the lower part of the rubber mat and press-molded at high temperature and high pressure in the mold.

The temperature and pressure are not particularly limited, but preferably 130 to 160 ° C and 100 to 200 kgf / cm ² .

When forming at high temperature and high pressure, the net tissue expands like a rubber mat by heat, but when the rubber mat shrinks, it shrinks together and is formed. Therefore, the net tissue catches the phenomenon of entering the middle part of the mat and lifting the edges. Can be prevented.

The rubber mat is a concept including a rubber block, and the rubber mat is not limited in kind as long as it is used for general walking. For example, the rubber mat may be press-molded in a mold by mixing a tire powder with a urethane binder.

In addition, the present invention is to put the material corresponding to 85 to 95% of the final thickness of the rubber mat in the mold, and after adding polypropylene, polyethylene or PVC net yarn at the bottom, the remaining thickness of the rubber mat at the bottom of the net yarn added Provided is a method for producing a rubber mat for preventing warpage, characterized in that the molding material is added to 5-15%.

The material is not limited in kind as long as it is a rubber mat material used for general walking, and may be, for example, a mixture of tire powder and urethane binder.

The method is adopted in order to solve the problem that the adhesion between the net tissue and the rubber mat is worse when the net tissue is not coated with a urethane solution, the lower part of the thickness of the rubber mat of the present invention It is a method that adds a net yarn without coating of urethane liquid so that the rubber mat exhibits warpage prevention function.

The rubber mat manufactured as described above exhibits the same action as that of the net yarn bonded to the lower portion of the rubber mat and can solve the problem of entering or lifting the rubber mat.

The present invention also provides a rubber mat for preventing warpage produced by the above production method.

The rubber mat containing the warp-resistant netting fabric of the present invention manufactured as described above has the appearance of the mat such that the center of the mat enters and the edge is lifted even when the pedestrians step on it for a long time when laid on the sandy bottom. A safe mat floor can be maintained without deformation.

2-1. Rubber Mat Manufacturing After Urethane Liquid Coating

After the urethane solution was dipped and coated, the net yarn prepared in 1. was attached to a lower portion of a rubber mat having a width of 500 mm, a length of 500 mm, and a thickness of 50 mm and compression molding in a mold machine.

2-2. A networked historian  Manufacture of rubber mats contained inside the mat

The tire powder and the urethane binder were mixed, and the amount to produce a rubber block 500 mm wide, 500 mm long and 40 mm thick was placed in the mold. Here, the net yarn prepared in 1. was put in the lower part, and the tire powder and the urethane binder were additionally mixed to form an additional amount corresponding to the remaining thickness of 10 mm.

3. Application to trails

1 month after laying the rubber mat (Example 1) and the rubber mat (Example 2) and the general rubber mat (Comparative Example) prepared according to 2-2. Afterwards, the appearance and cushioning of the mat were observed.

Mat center Matt corners Overall appearance Cushion Example 1 Flatness Flatness No change Good Example 2 Flatness Flatness No change Good Comparative example entry Protruding Irregular Irregularity

As shown in Table 1, in Example 1 and Example 2, the overall appearance, the center portion of the mat and the corner portion were almost unmodified, and the cushioning was good, but in the case of the comparative example, the overall appearance was irregular, and the center portion of the mat was Grooves, rising edges were observed, and cushioning irregularities were observed for each mat.
