It is a cross-sectional view, and FIG. 4 is a cross-sectional view showing a detailed configuration of the interior material of FIG. 3 .

1 to 3 , the eco-friendly exercise mat 100 according to an embodiment of the present invention may include an interior material 110 , an exterior material 120 , and a floor material 130 . On the other hand, it is preferable that the eco-friendly exercise mat 100 has a rectangular shape so that a plurality of them can be arranged adjacent to each other more easily.

First, the interior material 110 is a configuration that secures the elasticity of the eco-friendly exercise mat 100, it can be produced by utilizing polyester (Polyester, PET) fibers.

Polyester (PET) fiber has excellent resilience and is restored to its original state after being compressed, that is, it has excellent elasticity and resilience. This does not occur, and there is an advantage that an organic solvent is not applied.

In addition, since the interior material 110 is made of polyester fiber, it is possible to prevent yellowing and hardening powder.

In addition, the interior material 110 uses a low-melting-point (LM) fiber instead of a general adhesive for bonding, so it is more eco-friendly and has excellent rebound elasticity and compression set.

On the other hand, it is preferable that recycled polyester fibers are used as the polyester fibers, but the present invention is not limited thereto, and various polyester fibers may be applied.

Specifically, referring to Figure 4, the interior material 110 may include a plurality of interior material layers (111a, 111b, 111c), the bonding between the interior material layers (111a, 111b, 111c) low melting point (LM) fibers ( 112) can be done.

Each of the interior material layers 111a, 111b, and 111c may be manufactured by compressing polyester fibers in the form of a non-woven fabric.

As such, the interior material 110 is provided with a plurality of interior material layers 111a, 111b, and 111c so that the density of the interior material layers 111a, 111b, and 111c is formed differently from each other, so that the internal density of the interior material 110 increases with the height. This is to have a more desirable density, elasticity, strain rate, etc.

At this time, the interior material 110 is preferably formed so that the density of the interior material layer 111a located at the uppermost side among the plurality of interior material layers 111a, 111b, 111c is the highest, and the density gradually decreases toward the lower side. Without limitation, the density of the uppermost interior material layer 111a is the highest, and the density of the remaining interior material layers 111b and 111c may be easily changed, such as being identically formed.

More specifically, the plurality of interior material layers 111a, 111b, and 111c may include an interior material layer 111a of an uppermost layer, an interior material layer 111b of one or more intermediate layers, and an interior material layer 111c of the lowermost layer.

The uppermost interior material layer 111a has excellent elasticity and may be formed to have the highest density among the interior material layers 111a, 111b, and 111c in order to prevent an off phenomenon due to an external force.

A needle-punching process may be applied to the uppermost interior material layer 111a to increase the density and exhibit excellent elasticity. Accordingly, in the uppermost interior material layer 111a, the cohesion between the polyester fibers is increased to realize higher density and elasticity, thereby improving the impact dispersing effect and forming uniform elasticity over the entire area.

The density of the uppermost interior material layer 111a is preferably formed to be 150K or more, but is not limited thereto.

In addition, the top surface of the interior material layer 111a of the uppermost layer may be heat-treated, which is to make the adhesion with the exterior material 120 more robust.

The interior material layer 111b of the middle layer is a layer that supports the elasticity of the interior material layer 111a of the uppermost layer, and has a lower density than the interior material layer 111a of the uppermost layer, but has a density and elasticity to some extent so that it can be quickly restored in case of an impact by an external force. should have

Accordingly, the density of the interior material layer 111b of the intermediate layer is preferably formed in a range of 80 to 100K, but is not limited thereto.

As shown in FIG. 4 , the interior material layer 111b of the intermediate layer may be configured as one, but is not limited thereto, and may be configured in plurality.

The lowermost interior material layer 111c is a layer supporting the interior material layers 111a and 111b located on the upper side, and has a certain density to prevent the off (pressed) phenomenon.

In addition, the lowermost interior material layer 111c may be flattened by heat treatment on the lower surface so that the flooring 130 is more firmly attached to the lower side.

Preferably, the lowermost interior material layer 111c has a density of 80 to 100K, but is not limited thereto.

The interior material layers 111a, 111b, and 111c configured as described above have heated low-melting fibers disposed therebetween, are adhered to each other, and a certain pressure is applied to fix the bonding state, thereby forming one interior material 110 .

The exterior material 120 is made of an eco-friendly fabric, and is formed so as to cover a portion of the interior material 110 from the upper surface to the lower surface, that is, to surround the upper surface, side and lower edges of the interior material 110, and foreign substances or moisture, etc. to the interior material 110 It can be protected from penetration.

Here, the eco-friendly fabric may be a PVC fabric, a welfare fabric, a canvas fabric, etc., but is not limited thereto, and various eco-friendly fabrics may be applied.

More specifically, the exterior material 120 may be formed to have a double structure of polyvinyl chloride (PVC) fabric and welfare fabric or canvas fabric. By being formed in this way, it is possible to further prevent the pressing phenomenon of the eco-friendly exercise mat 100 and to receive elasticity as a whole, and to maintain the mat shape for a long time.

In addition, since the exterior material 120 is finished with corners and the like through heat welding, durability can be further maximized.

The flooring 130 is formed to have a non-slip function through morphological features or material features such as non-slip protrusions, and is attached to the lower surface of the interior material 110 to prevent the eco-friendly exercise mat 100 from being pushed. Accordingly, it is possible to block the possibility of accidents such as injuries due to the pushing of the eco-friendly exercise mat 100 .

Such a flooring material 130 may be formed of a material such as silicone, polyvinyl chloride (PVC), polyester, but is not limited thereto.

In addition, the flooring 130 may include a coating layer formed by coating the coating composition on the surface.

Methyl methacrylate resin is a thermosetting acrylic resin, which is based on eco-friendliness, increases durability, water resistance, and weather resistance, and has antibacterial and non-toxic properties. In addition, it has excellent viscosity to increase adhesion and to improve strength due to curing. When the amount of the methyl methacrylate resin is less than 20 parts by weight, the improvement effect such as durability is insignificant, and when it exceeds 40 parts by weight, it may be rather unsuitable for forming a coating layer.

Polyurethane acrylate resin is an oligomer, environmentally friendly, has excellent chemical resistance characteristics, and is suitable for coating. If it is out of the above range, coating workability may be reduced.

The polyorganosiloxane resin increases impact strength and durability and has a flame retardancy. If it is out of the above range, it is difficult to exhibit a desirable effect and rather a problem may occur in the coating.

The fluororesin is preferably a Teflon resin, may have a hydroxyl group, and exhibit an antifouling function. If it is less than 15 parts by weight, the antifouling effect may be reduced, and if it exceeds 20 parts by weight, physical properties may be reduced.

Alkyltrichlorosilane changes the surface energy of the coating to further improve the antifouling function of the fluororesin. If it is less than 5 parts by weight, it does not show a desirable effect, and if it exceeds 10 parts by weight, unreacted substances remain and the coating property is rather reduced. can be

The curing agent may include one or more of propylene glycol monomethyl ether acetate, dimethyl carbonate, and polyisocyanate, preferably dimethyl carbonate, but is not limited thereto, and various environmentally friendly curing agents may be applied.

The functional additive may include at least one of metallocene polyethylene (m-PE) and disodium succinate, and preferably includes all of them, but is not limited thereto.

Metallocene polyethylene (m-PE) is a composition prepared using a metallocene catalyst, has a characteristic of improving moisture resistance, and may contain 3 to 8 parts by weight, but is not limited thereto.

Disodium succinate improves adhesion to exhibit coating properties improvement and peeling prevention effects, and may include 0.5 to 2.5 parts by weight, but is not limited thereto.

It is preferable for the effective functionality of the coating layer to include the resin, curing agent and functional additive in an amount of 60 to 100 parts by weight of the resin, 12 to 20 parts by weight of the curing agent and 12 to 20 parts by weight of the functional additive in the coating composition, but is not limited thereto.

On the other hand, the flooring 130 and the exterior material 120 may be attached through the interior material 110 and the low-melting fiber. At this time, it is preferable that all surfaces of the exterior material 120 and the interior material 110 contact each other to prevent the exterior material 120 from being stretched and torn.

In the interior material layer manufacturing step (S100), a plurality of interior material layers 111a, 111b, and 111c may be manufactured by using polyester fibers.

In step S100, polyester fibers are produced in the form of a non-woven fabric and then compressed to produce interior material layers 111a, 111b, and 111c. A plurality of interior material layers 111a, 111b, and 111c are respectively produced to form different densities. can make it happen

Here, when the polyester fiber is produced in the form of a non-woven fabric, the polyester fiber is formed in a web form and can be manufactured in a non-woven form through thermal fusion. can be manufactured with

In this case, the thermal fusion may be performed by using one of heating, hot air, radiant heat (infrared), and vibration energy (ultrasound, high frequency, etc.).

In step S100, the compression may be made at a temperature of 240 to 260 ℃ during compression. If it is less than 240 ℃, compression may not be properly performed to the desired density, and if it exceeds 260 ℃, fiber damage, breakage, etc. may occur. .

The layer bonding step (S101) is a step of bonding the plurality of interior material layers (111a, 111b, 111c) prepared in step S100 to be bonded to each other, and may be adhered using a low melting point (LM) fiber 112 .

In step S101, the heated low-melting-point fiber 112 is disposed between the interior material layers 111a, 111b, and 111c to be adhered, and then compressed with a predetermined pressure so that the adhesive state is more firmly fixed.

At this time, heat of 80 to 100° C. may be applied to the low melting point fiber 112 , which is applied to the low melting point fiber 112 to form viscosity so that adhesion is achieved. When the heating is made less than 80 ℃, the viscosity cannot be sufficiently formed, and when it is more than 100 ℃, the adhesive workability is deteriorated due to overdissolution and distortion between the layers may occur.

The processing step (S102) is a step of performing a needle punching process on the interior material layer 111a of the uppermost layer or heat-treating the interior material layer 111c of the lowermost layer, and only one of the two treatments or both may be performed.

The exterior material manufacturing step (S11) is a step of manufacturing the exterior material 120 from an eco-friendly fabric, and the exterior material 120 may be manufactured to have a double structure. In this case, the adhesion between the fabrics constituting the double structure may use a low-melting fiber, but is not limited thereto, and an eco-friendly adhesive or the like may be applied.

The order of the interior material manufacturing step (S10), the exterior material manufacturing step (S11), the flooring manufacturing step (not shown), etc. in step S1 is not limited, and may be performed in various orders or simultaneously.

The temporary bonding step (S2) is a step of temporarily adhering the low-melting-point fibers to the exterior material 120 and the flooring 130, respectively, by applying heat of 80 to 100° C. to the low-melting-point (LM) fibers using a laminating machine or laminating machine. It may be temporarily attached to the exterior material 120 or the floor material 130 .

At this time, the low-melting-point fiber has an adhesive force through heating, but is not completely melted and can be attached to the exterior material 120 or the floor material 130 .

In addition, in step S2, as shown in FIG. 8 , the exterior material 120 or the floor material 130 and the low-melting point fiber are adhered to each other through a roller (R) and compressed under a certain pressure, thereby the exterior material 120 or Adhesion between the flooring 130 and the low-melting fiber may be further improved.

In step S2, a heater is configured on the conveyor to heat the low-melting fiber, or the roller (R) is configured as a heating roller to heat the low-melting fiber, but is not limited thereto.

The cutting step (S3) may be cut according to the size of the eco-friendly exercise mat 100 to be manufactured the interior material 110, the flooring 130 to which the low-melting-point fiber is adhered, and the exterior material 120. At this time, the interior material 110 and the floor material 130 are cut to have the same size, and the exterior material 120 may be cut to a size that can cover the upper surface, the side surface, and the lower surface of the interior material 110, but is not limited thereto. .

The attaching step (S4) is a step in which the exterior material 120, interior material 110, and floor material 130 cut in a predetermined frame are arranged in a mat form, heat is applied, and the material is pressed under a certain pressure to attach the mat type to be manufactured. can form.

At this time, in step S4, heat is applied to completely melt the low-melting-point fibers adhered to the exterior material 120 and the floor material 130 so that the exterior material 120, the interior material 110, and the floor material 130 are attached to each other.

Here, the heating is preferably made at 80 to 100 ℃, but is not limited thereto.

In addition, in step S4, the model of the mat manufactured by putting it in a certain frame and applying pressure can be prevented from being deformed.

In addition, the low-melting-point fiber acting as an adhesive is evenly spread through compression to achieve uniform attachment, so that the shape can be firmly fixed.

To this end, step S4 can be compressed for 1 to 2 minutes at a pressure of 9.0 bar or less, which may make it difficult to maintain the shape of the mat if it exceeds 9.0 bar, and rather for formability, such as low-melting fiber flowing out to the side. Problems may appear.

The aging step (S5) is a step of aging while compressing the exterior material 120, interior material 110, and floor material 130 attached in step S4. With pressure, it may be desirable to do it for 8 to 12 hours.

This may cause problems in molding if the pressure exceeds 12 MPa. In addition, if it proceeds for less than 8 hours, the effect through step S5 may not appear preferably, and if it proceeds for more than 12 hours, it may be inefficient as the adhesion is already sufficiently completed.

If the finishing step (S6) is performed immediately without proceeding to step S5, the model of the eco-friendly exercise mat 100 may be deformed because the adhesion is not completely fixed, and defects such as reduced durability may occur.

In the finishing step (S6), after step S5, the exterior material 120 is finished to surround a portion of the interior material 110 and the floor material 130 through thermal welding of the exterior material 120 to manufacture the eco-friendly exercise mat 100. can Since the finish of the exterior material 120 is achieved through the thermal melting point, it is possible to more effectively prevent the penetration of foreign substances and moisture into the interior.
