Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic running track technology, and more specifically, to a running track with flame-retardant plastic granules. Background Technology
[0002] Plastic running tracks, also known as all-weather athletic tracks, are characterized by their flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. They are conducive to athletes' speed and technique, effectively improving athletic performance, reducing the rate of falls and injuries, and have a certain degree of elasticity and color. They also have a certain degree of UV resistance and aging resistance, making them internationally recognized as the best all-weather outdoor sports flooring material.
[0003] Existing plastic running tracks only have flame-retardant granules attached to the surface to reduce the probability of fire spread in the event of a fire, and their flame-retardant and fire-resistant safety needs to be further improved. In addition, plastic running tracks do not have water permeability, and after rain, a large amount of water will accumulate, affecting subsequent use. In summary, the performance of plastic running tracks needs to be optimized in these two aspects. Utility Model Content
[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a running track with flame-retardant plastic particles.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A running track with flame-retardant plastic granules includes a base layer and a surface layer. The base layer is adhesively bonded to the ground surface, and the surface layer has flame-retardant granules formed on it.
[0007] A waterproof layer is installed on the outer side of the bottom layer;
[0008] The outer side of the waterproof layer is staggered with light gray flexible flame-retardant roll sponge layer and water-absorbing layer;
[0009] A highly absorbent composite resin layer is provided on the outer side of the light gray flexible flame retardant roll sponge layer and the water-absorbing layer.
[0010] A surface layer is provided on the outer side of the superabsorbent composite resin layer;
[0011] Several through holes are opened on the surface.
[0012] Furthermore, the outer side of the light gray flexible flame-retardant roll sponge layer is provided with a nano-coating.
[0013] The above solution involves covering the surface of the light gray flexible flame retardant roll sponge layer with a nano-coating, which prevents water from accumulating on the surface of the light gray flexible flame retardant roll sponge layer, thereby avoiding the problem of water accumulation on its surface and extending its service life.
[0014] Furthermore, the superabsorbent composite resin layer is provided with warp-knitted spacer fabric inside.
[0015] The above solution can further improve the water absorption effect of the super absorbent composite resin layer by setting warp-knitted spacer fabric inside the super absorbent composite resin layer, and at the same time improve the air permeability of the super absorbent composite resin layer, thus facilitating the rapid evaporation of its internal moisture.
[0016] Furthermore, a polyurethane prepolymer layer is provided on the outer side of the surface layer, and the polyurethane prepolymer layer has drainage holes that correspond one-to-one with and communicate with the through holes.
[0017] The above solution can further improve the elasticity and wear resistance of the plastic running track by setting a polyurethane prepolymer layer on the outer surface, thus making the plastic running track more comfortable to use.
[0018] Furthermore, the bottom layer has several countersunk holes, and rubber nails are installed inside the countersunk holes.
[0019] The above solution, which uses rubber nails in combination with adhesive, can ensure sufficient density of the base layer to prevent localized bubbling and peeling after the adhesive surface is laid.
[0020] Furthermore, the aforementioned underlying layers are sequentially spliced together end to end.
[0021] Furthermore, a sealing ring is provided at the joint between adjacent layers.
[0022] In the above scheme, the bottom layer of the plastic running track adopts a splicing design to facilitate subsequent partial replacement.
[0023] Furthermore, a drainage net is installed inside the drainage hole.
[0024] In the above scheme, the drainage net can improve the leakage efficiency of the drainage holes.
[0025] Compared with the prior art, the beneficial effects of this utility model are:
[0026] Compared to existing technologies, this device effectively reduces the amount of rainwater accumulating on the surface of the plastic running track by combining rapid water leakage with high water absorption, thus achieving a water seepage effect. At the same time, the use of flame-retardant granules combined with a light gray flexible flame-retardant roll sponge layer can further improve the flame-retardant safety of the plastic running track in the event of a fire, and the flame-retardant and water-reducing performance are further improved.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:
[0031] like Figure 1 As shown, a running track with flame-retardant plastic granules includes a bottom layer 1 and a top layer 6. The bottom layer 1 is adhesively bonded to the ground surface, and the top layer 6 has flame-retardant granules formed on it.
[0032] A waterproof layer 2 is provided on the outer side of the bottom layer 1;
[0033] The outer side of the waterproof layer 2 is staggered with a light gray flexible flame-retardant roll sponge layer 3 and a water-absorbing layer 4;
[0034] A highly absorbent composite resin layer 5 is provided on the outer side of the light gray flexible flame retardant roll sponge layer 3 and the water-absorbing layer 4.
[0035] A surface layer 6 is provided on the outer side of the superabsorbent composite resin layer 5;
[0036] Several through holes are provided on the surface layer 6, which are not shown in the figure.
[0037] A further refinement of the embodiment of this utility model is that several bottom layers 1 are sequentially and movably spliced together end to end, and a sealing ring is provided at the splice seam of adjacent bottom layers 1; this embodiment is not shown in the figure.
[0038] In a further optimization of the above embodiment, a plurality of countersunk holes 8 are provided on the bottom layer 1, and rubber nails are provided in the countersunk holes 8. The rubber nails are not shown in the figure. By using rubber nails in combination with adhesive, the density of the bottom layer 1 can be ensured to prevent local bubbling and peeling after the adhesive surface is laid.
[0039] The working process of this utility model:
[0040] First, several through holes are made on the surface layer 6 so that rainwater can naturally seep down and reduce the amount of water accumulating on the surface layer 6. The rainwater then reaches the super absorbent composite resin layer 5 for effective adsorption. After being adsorbed by the super absorbent composite resin layer 5, most of the rainwater is adsorbed. Then a small amount of water continues to flow downwards. After being adsorbed by the water-absorbing layer 4 and blocked by the waterproof layer 2, rainwater can be prevented from penetrating to the bottom layer 1 of the plastic track. The bottom layer 1 of the track adopts a splicing design to facilitate subsequent partial replacement.
[0041] Meanwhile, setting a light gray flexible flame-retardant roll sponge layer 3 on the outside of the waterproof layer 2 can further improve the flame-retardant performance of the plastic track. That is, when a fire occurs, the fire source first comes into contact with the flame-retardant particles on the surface layer 6 for fire prevention. If the fire source is large, the light gray flexible flame-retardant roll sponge layer 3 inside the plastic track can provide double fire prevention and flame retardancy, thereby effectively reducing the probability of fire spread and further improving safety performance. The two flame-retardant measures promote each other.
[0042] In some embodiments, a nano-coating is provided on the outer side of the light gray flexible flame retardant roll sponge layer 3; this embodiment prevents water from accumulating on the surface of the light gray flexible flame retardant roll sponge layer 3 by covering the surface with a nano-coating, thereby avoiding the problem of water accumulation on its surface and extending its service life.
[0043] In other embodiments, a warp-knitted spacer fabric is provided inside the superabsorbent composite resin layer 5; this embodiment can further improve the water absorption effect of the superabsorbent composite resin layer 5 by providing a warp-knitted spacer fabric inside the superabsorbent composite resin layer 5, and at the same time improve the air permeability of the superabsorbent composite resin layer 5, thereby facilitating the rapid evaporation of its internal moisture.
[0044] In other embodiments, such as Figure 1 As shown, a polyurethane prepolymer layer 7 is provided on the outer side of the surface layer 6. The polyurethane prepolymer layer 7 has drainage holes that correspond one-to-one with and are connected to the through holes. The drainage holes are not shown in the figure.
[0045] In a further optimization of the above embodiment, a drainage net is provided inside the drainage hole, which is not shown in the figure. This embodiment can further improve the elasticity and wear resistance of the plastic track by providing a polyurethane prepolymer layer 7 on the outside of the surface layer 6, thereby making the use of the plastic track more comfortable. At the same time, the drainage net can improve the drainage efficiency of the drainage hole.
[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
