Description

Technical Field

[0001] This utility model relates to the technical field of plastic running tracks, and in particular to a plastic running track with good wear resistance and pressure resistance. Background Technology

[0002] Currently, in order to save costs, the synthetic running tracks in schools or fitness parks are generally made of a single layer of synthetic material or a composite layer of two layers of synthetic material and rubber. Traditional synthetic running tracks have poor wear resistance and pressure resistance. On the one hand, they do not provide enough cushioning and shock absorption for athletes' joints, such as ankles, which can easily cause joint wear or injury. On the other hand, the track has a short service life. Frequent use in certain areas can cause inconspicuous indentations in the track. When athletes step on these indentations, the uneven force on their feet can lead to bruises.

[0003] This application provides an improved plastic running track to solve the above-mentioned technical problems and improve the performance of the running track. Utility Model Content

[0004] The purpose of this invention is to provide a plastic running track with good wear resistance and pressure resistance, exhibiting superior performance. The technical solution adopted by this invention is as follows:

[0005] A wear-resistant and pressure-resistant plastic running track includes a base layer, which is a pre-cast building foundation surface, such as a cement layer; above the base layer, from bottom to top, there are a first buffer layer, a shock-absorbing and reinforcing layer, a second buffer layer, and a wear-resistant layer.

[0006] The upper surface of the shock-absorbing reinforcement layer has a plurality of concave damping grooves, which are spaced apart from each other and arranged in parallel, and extend along the length of the track; the bottom surface of the second buffer layer has a plurality of downwardly protruding vibration-transmitting protrusions, which are arranged in a one-to-one correspondence with the damping grooves; when the second buffer layer is bonded to the upper surface of the shock-absorbing reinforcement layer, the vibration-transmitting protrusions are inserted into the damping grooves one-to-one.

[0007] The interior of the shock-absorbing reinforcement layer consists of several shock-absorbing supports and a hydrophobic filler between the shock-absorbing supports; the shock-absorbing supports are trapezoidal in shape, narrower at the top and wider at the bottom, and are located below the bottom of the several shock-absorbing grooves; the shock-absorbing supports serve to strengthen the support, prevent the runway from collapsing under pressure, and provide shock absorption.

[0008] Preferably, the hydrophobic filler has hydrophobic pores, and the shock-absorbing reinforcement layer is located on at least one side of the runway in the width direction, which is the hydrophobic filler and connected to a drainage pipe.

[0009] More preferably, the hydrophobic filler has a porous honeycomb structure and a molecular weight exceeding 7.8 × 10⁻⁶. 6 PU polymer.

[0010] Preferably, the vibration-transmitting protrusion is slightly narrower than the damping groove, and when the second buffer layer is adhered above the damping reinforcement layer, a gap is formed between the outer wall of the vibration-transmitting protrusion and the inner wall of the damping groove.

[0011] Furthermore, the inner wall of the shock-absorbing groove is also bonded with a high-elasticity rubber layer. Preferably, the high-elasticity rubber layer has a molecular weight exceeding 1.8 × 10⁻⁶. 6 It is made of rubber.

[0012] Preferably, the shock-absorbing support is made of EPDM rubber material modified with carbon nanotubes.

[0013] Furthermore, the first buffer layer and / or the second buffer layer are formed by bonding together several layers of tire rubber. Preferably, the bonding surfaces of the several layers of tire rubber are wavy and non-planar, and the several layers of tire rubber are bonded together seamlessly.

[0014] Furthermore, the surface of the wear-resistant layer is formed with raised anti-slip textures. The anti-slip textures can be continuous or discontinuous, and can be regular or irregular.

[0015] The plastic running track provided by this utility model has improved shock absorption and avoidance of dents due to stress by improving its layers and internal structure, resulting in better sports comfort and a longer service life. Attached Figure Description

Above the base layer 1, from bottom to top, there are a first buffer layer 2, a shock-absorbing and reinforcing layer 3, a second buffer layer 4, and a wear-resistant layer 5.

[0024] like Figure 1 and Figure 2 As shown, the upper surface of the shock-absorbing reinforcement layer 3 has several concave damping grooves 31, which are spaced apart and arranged parallel to each other, extending along the length of the runway. The bottom surface of the second buffer layer 4 has several downwardly protruding shock-transmitting protrusions 41, which correspond one-to-one with the damping grooves 31. When the second buffer layer 4 is bonded to the upper surface of the shock-absorbing reinforcement layer 3, the shock-transmitting protrusions 41 are inserted into the damping grooves 31, and the protrusions 41 are slightly narrower than the grooves. A gap is formed between the outer wall of the protrusions 41 and the inner wall of the grooves 31, providing a damping effect. Furthermore, a high-elasticity rubber layer 32 is bonded to the inner wall of the damping grooves 31. The high-elasticity rubber layer 32 has a molecular weight exceeding 1.8 × 10⁻⁶. 6 Made of rubber, it has excellent rebound and cushioning properties.

[0025] like Figure 1 and Figure 2 As shown, the internal structure of the shock-absorbing reinforcement layer 3 consists of several shock-absorbing supports 33 and hydrophobic fillers 34 filling the spaces between the shock-absorbing supports 33. The shock-absorbing supports 33 are trapezoidal in shape, narrower at the top and wider at the bottom, and are positioned below the bottom of several shock-absorbing grooves 31. In this embodiment, several spaced-apart shock-absorbing supports 33 are provided below the bottom of each shock-absorbing groove 31. Alternatively, a continuous, elongated trapezoidal shock-absorbing support 33 can be provided below the bottom of each shock-absorbing groove 31. The shock-absorbing supports 33 are made of EPDM rubber material modified with carbon nanotubes, serving to strengthen support, prevent the track from collapsing under pressure, and provide shock absorption. The hydrophobic fillers 34 have hydrophobic pores, preferably with a porous honeycomb structure (not shown in the figure), and a molecular weight exceeding 7.8 × 10⁻⁶. 6 The PU polymer. The shock-absorbing reinforcement layer 3 is a hydrophobic filler 34 located on at least one side in the width direction of the runway and is connected to a drainage pipe 6. The drainage pipe 6 extends outward from the runway and is used for water drainage.

[0026] like Figure 3 and Figure 4 As shown, in this embodiment, the first buffer layer 2 is formed by bonding three layers of tire rubber 7, and the second buffer layer 4 is formed by bonding four layers of tire rubber 7. The bonding surfaces between the tire rubber layers 7 are all wavy and non-planar, and adjacent tire rubber layers 7 are seamlessly bonded together.

[0027] In this embodiment, the wear-resistant layer 5 is made of PU material, and its surface has raised anti-slip textures (not shown in the figure). The anti-slip textures can be continuous or discontinuous, and can be regular or irregular.
