Description

Technical Field

[0001] This utility model relates to the field of flooring technology, specifically an EPDM elastic particle flooring. Background Technology

[0002] Synthetic running tracks, also known as athletic tracks, are composed of polyurethane prepolymer, mixed polyethers, waste tire rubber, EPDM rubber granules or PU particles, pigments, additives, and fillers. Synthetic running tracks are characterized by good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which are conducive to athletes' speed and technique, effectively improving athletic performance and reducing the rate of falls and injuries. Composed of materials such as polyurethane rubber, synthetic running tracks possess a certain degree of elasticity and color, and have a certain resistance to ultraviolet rays and aging, making them internationally recognized as the best all-weather outdoor sports flooring material. Currently, however, synthetic running tracks have relatively poor drainage performance; rainwater easily accumulates on the surface, which can reduce the lifespan of the track over time. Utility Model Content

[0003] The purpose of this invention is to provide an EPDM elastic particle flooring to solve the problems in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an EPDM elastic particle flooring, comprising a crushed stone layer, a hydrophobic layer retainer, a hydrophobic layer, a wire mesh layer, and a surface layer. The hydrophobic layer retainer is laid flat on the crushed stone layer, the hydrophobic layer is filled inside the hydrophobic layer retainer, the wire mesh layer is laid flat on top of the hydrophobic layer, the surface layer is coated on the wire mesh layer, and the surface layer is provided with hydrophobic holes.

[0005] Preferably, the hydrophobic layer is composed of large-diameter EPDM elastic particles with a diameter of 5-10 mm.

[0006] Preferably, the surface layer is composed of small-diameter EPDM elastic particles mixed with acrylic acid, and the diameter of the small-diameter EPDM elastic particles is 2-4 mm.

[0007] Preferably, the hydrophobic layer retainer consists of side baffles, support feet, and connecting plates. Multiple support feet are fixed at equal intervals on the side of the side baffles. Two side baffles are provided and arranged on both sides of the crushed stone layer. The support feet are embedded in the interior of the crushed stone layer. Multiple connecting plates are fixed at equal intervals between the two side baffles.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: the surface layer of this utility model is provided with hydrophobic holes, which allow rainwater to penetrate downwards. After passing through the hydrophobic layer and the gravel layer, it can enter the soil, thereby preventing rainwater from stagnating on the track. The hydrophobic layer retainer can prevent the hydrophobic layer from being lost due to long-term rainwater infiltration. The added wire mesh layer can improve the strength of the surface layer, making it less prone to cracking. At the same time, when the surface layer needs to be replaced after damage, the wire mesh layer also makes it easier to separate the surface layer.

[0009] The hydrophobic layer of this invention is made of large-diameter EPDM elastic particles. The gaps between the large-diameter EPDM elastic particles facilitate the penetration of rainwater, while also giving the hydrophobic layer good elasticity, which helps to improve user comfort.

[0015] Please see Figure 1-2In this embodiment of the present invention, an EPDM elastic particle flooring includes a gravel layer 1, a hydrophobic layer retainer 2, a hydrophobic layer 3, a wire mesh layer 4, and a surface layer 5. The hydrophobic layer retainer 2 is laid flat on the gravel layer 1, the hydrophobic layer 3 is filled inside the hydrophobic layer retainer 2, the wire mesh layer 4 is laid flat on top of the hydrophobic layer 3, and the surface layer 5 is coated on the wire mesh layer 4.

The hydrophobic layer retainer 2 is composed of side baffles 6, support feet 7, and connecting plates 8. Multiple support feet 7 are fixed at equal intervals on the side of the side baffles 6. Two side baffles 6 are provided and arranged on both sides of the gravel layer 1. The support feet 7 are buried inside the gravel layer 1.

[0017] The working principle of this utility model is as follows: The surface layer 5 of this utility model is provided with water-repellent holes, and rainwater can penetrate downward through the water-repellent holes. After passing through the water-repellent layer 3 and the gravel layer 1, it can enter the soil, thereby preventing rainwater from stagnating on the track. The water-repellent layer retainer 2 can prevent the water-repellent layer 3 from being lost due to long-term rainwater infiltration.
