Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly specified and limited.
[0029] In the embodiments of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication or interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.
[0030] In one embodiment of the present application, according to Figure 1 and 2 As shown in FIG. 1, a prefabricated polyurethane track and field coil material is provided with a base layer 100 on the ground, including a treatment layer 200, the treatment layer 200 is coated on the base layer 100, the treatment layer 200 is provided with an adhesive layer 300, the adhesive layer 300 is provided with a polyurethane elastic layer 400, the polyurethane elastic layer 400 is provided with a reinforcing layer 500, the reinforcing layer 500 is provided with a surface layer 600, and the surface layer 600 is provided with a line.
[0031] Specifically, the resilience of the runway can be enhanced by arranging the polyurethane elastic layer 400, the overall strength can be improved by arranging the reinforcing layer 500 on the polyurethane elastic layer 400, meanwhile, the reinforcing layer 500 is harder than the polyurethane elastic layer 400, so that the effect of hard on the top and soft on the bottom is achieved, the wear resistance can be improved by arranging the surface layer 600 on the reinforcing layer 500, so that the entire runway is durable, meanwhile, the prefabricated polyurethane runway court coiled material is quiet and noiseless during paving, is environment-friendly, can be replaced in time when partial damage occurs, and the replacement cost is low.
[0032] In another embodiment of the present application, according to Figure 1 and 2 , the material of the base layer 100 is cement or asphalt. The base layer 1001 is cement or asphalt, which is first laid flat to facilitate personnel to construct the runway and improve the stability of the runway.
[0033] In another embodiment of the present application, according to Figure 1 and 2 , the treatment layer 200 is a single-component sealing primer. Specifically, the single-component sealing primer is a primer material for pretreatment of the surface of the base material. The main function is to penetrate the surface layer of the base material, form a dense protective film, and improve the adhesion and protection performance of the coating system. By coating the single-component sealing primer, the adhesion between the base layer 100 and the adhesive layer 300 can be increased, so that cracking and peeling between the base layer 100 and the polyurethane elastic layer 400 do not occur.
[0034] In another embodiment of the present application, according to Figure 1 and 2 , the thickness of the polyurethane elastic layer 400 is 3-5mm. Specifically, if the thickness of the polyurethane elastic layer 400 is too thin, the buffering performance will decrease: the thin elastic layer cannot provide sufficient buffering and resilience, cannot effectively absorb the impact force during the movement, and the experience is poor. If the thickness of the polyurethane elastic layer 400 is too thick, the softness is excessive: the thick elastic layer can be too soft, so that the athlete feels unstable when running.
[0035] In another embodiment of the present application, according to Figure 1 and 2As shown, the reinforcing layer 500 is a polyurethane reinforcing layer 500, and the surface layer 600 is a polyurethane surface layer 600. The wear resistance of the surface layer 600 is greater than that of the reinforcing layer 500, and the elasticity of the polyurethane elastic layer 400 is greater than that of the reinforcing layer 500. The addition of the polyurethane elastic layer 400 enhances the track's resilience. The reinforcing layer 500, placed on top of the polyurethane elastic layer 400, improves the overall strength. Furthermore, the reinforcing layer 500 has a higher hardness than the polyurethane elastic layer 400, achieving a "resilient at the bottom, hard at the top" effect. The surface layer 600, placed on top of the reinforcing layer 500, further increases wear resistance, making the entire track durable.
[0036] In another embodiment of this utility model, according to Figure 1 and 2 As shown, the surface texture of the top layer 600 is a granular texture, a self-sprung texture, or a corn-like texture. Specifically, the texture of the top layer 600 can increase the contact area, increase friction, and improve wear resistance and anti-slip properties.
[0037] In another embodiment of this utility model, according to Figure 1 and 2 As shown, the lines are 5cm wide and are used to outline the boundaries and dividing lines of the track.
[0038] In another embodiment of this utility model, according to Figure 1 and 2 As shown, a fluorescent layer 700 is also provided between the reinforcing layer 500 and the surface layer 600. When the surface layer 600 is damaged, the fluorescent layer 700 serves as a warning. Specifically, when the surface layer 600 is damaged, creating pits, the fluorescent layer 700 at the bottom will be exposed. This will be clearly visible during night runs, serving to remind passersby and runners to be careful of the pits.
[0039] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
