[0006] Therefore, a wear -resisting composite silicon PU court surface layer is designed to optimize the above problems. UTILITY MODEL CONTENTS

[0007] The main purpose of the utility model is to provide a kind of wear -resisting composite silicon PU court surface layer, to solve the relevant technical problems proposed in the above background art.

[0013] Preferably: the clamping block is trapezoidal block, the limiting slot is inverted trapezoidal slot, and the limiting slot and the clamping block are provided with adhesive layer.

[0014] Preferably: the aperture of the water seepage hole is smaller than the aperture of the drainage hole, and the drainage hole is tapered hole.

[0015] The utility model has the advantages that:

[0016] The wear-resistant composite silicon PU court surface layer provided by the utility model cooperates the base layer, buffer layer one, limiting slot, buffer layer two, limiting block, clamping block, through-hole, buffer strip, wear-resistant layer one, water-based paint surface and silicon PU layer, can increase the adhesive fixing area between buffer layer one and buffer layer two, not only increases resistance and is not easy to produce sliding dislocation, but also improves the overall buffering effect through the setting of through-hole and clamping block, so as to improve the firmness of the wear-resistant composite silicon PU court surface layer.

[0017] Through the cooperation of silane coupling agent solution layer and wear-resistant layer two, the silane coupling agent solution layer is laid on the top of the buffer layer two, and then the silane coupling agent solution layer and wear-resistant layer two are laid, the silane coupling agent solution layer can increase the contact area of the silicon PU layer and wear-resistant layer two, promote the adhesion to be more firm, the components in the silane coupling agent solution layer and wear-resistant layer two and the components in the silicon PU layer occur chemical reaction, form chemical bond, so as to enhance the bonding force between two layers and further enhance the adhesion.

[0018] By using a combination of a waterproof layer, a water-absorbing layer, drainage holes, and seepage holes, water on the top of the water-based paint surface seeps into the bottom water-absorbing layer through the seepage holes. The water-absorbing layer then absorbs the water in its pores. When the water-based paint surface is stepped on and squeezed, the drainage holes are deformed by the pressure, causing water to be discharged outwards under the impact. Since the diameter of the seepage holes is smaller than that of the drainage holes, the resistance is greater, and more water is discharged from the drainage holes, thereby reducing water accumulation on the top of the water-based paint surface and improving the safety of this wear-resistant composite silicone PU court surface layer.

[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] Example 1

[0025] like Figures 1-3 As shown, this embodiment provides a wear-resistant composite silicone PU sports court surface layer, including a base layer 1, a buffer layer 2 fixed on top of the base layer 1, a limiting groove 3 uniformly opened on the top of the buffer layer 2, a buffer layer 4 on top of the buffer layer 2, limiting blocks 5 uniformly arranged on the bottom of the buffer layer 4, a locking block 6 fixed on the bottom of each limiting block 5, and the locking block 6 and the limiting groove 3 engaging with each other, through holes 7 are opened inside the buffer layer 4, buffer strips 8 are fixed inside the through holes 7, a silicone PU layer 11 is installed on top of the buffer layer 4, a silane coupling agent solution layer 12 is laid on top of the silicone PU layer 11, a waterproof layer 13 is provided on top of the silane coupling agent solution layer 12, and a wear-resistant layer 17 is provided on top of the waterproof layer 13.

[0026] During installation, buffer layer 2 4 is laid on top of buffer layer 1 2, so that the limiting block 5 and the locking block 6 are engaged inside the limiting groove 3. Then, the upper layer, such as the silane coupling agent solution layer 12, is laid. When the top of the water-based paint surface 10 is squeezed and impacted, the force is transmitted downward to buffer layer 2 4. Under the elastic force of the through hole 7, the rebound reaction force acts as a buffer and shock absorber. The circular through hole 7 further enhances the buffering effect. The mutual engagement of the limiting groove 3, the limiting block 5, and the locking block 6 ensures adhesion between buffer layer 1 2 and buffer layer 2 4. With a larger area, the resistance is also greater, making it more difficult for the second buffer layer 4 to separate from the first buffer layer 2. A silicone PU layer 11 is laid on top of the second buffer layer 4, followed by a silane coupling agent solution layer 12 and a wear-resistant layer 2 17. The silane coupling agent solution layer 12 increases the contact area between the silicone PU layer 11 and the wear-resistant layer 2 17, promoting a stronger bond. The components in the silane coupling agent solution layer 12 and the wear-resistant layer 2 17 react chemically with the components in the silicone PU layer 11 to form chemical bonds, thereby enhancing the bonding force between the two layers and further strengthening the adhesion.

[0027] Example 2

[0028] In this embodiment, as Figures 1-3 As shown, a water-absorbing layer 14 is provided on the top of the wear-resistant layer 2 17, and drainage holes 15 are evenly provided on both sides of the water-absorbing layer 14. A wear-resistant layer 1 9 is fixed on the top of the water-absorbing layer 14, and a water-based paint surface 10 is provided on the top of the wear-resistant layer 19. Water seepage holes 16 are evenly provided on the top of the water-based paint surface 10 and the wear-resistant layer 19.

[0029] Water on the top of the water-based paint surface 10 seeps into the bottom absorbent layer 14 through the seepage hole 16. The absorbent layer 14 adsorbs the water into the gaps within it. When the water-based paint surface 10 is stepped on and squeezed, the drain hole 15 is deformed by the pressure. Under the impact, the water is discharged out of the drain hole 15. Since the diameter of the seepage hole 16 is smaller than that of the drain hole 15, the resistance is greater than that of the drain hole 15. More water is discharged from the drain hole 15, thereby reducing the water accumulation on the top of the water-based paint surface 10.

[0030] In this embodiment, all buffer strips 8 are cylindrical strips, and an anti-slip layer is provided on the outer side of the buffer strips 8.

[0031] The cylindrical buffer strip 8 further increases the cushioning force, and the anti-slip layer increases the friction with the through hole 7.

[0032] In this embodiment, the card block 6 is a trapezoidal block, the limiting groove 3 is an inverted trapezoidal groove, and an adhesive layer is provided between the limiting groove 3 and the card block 6.

[0033] The adhesive layer increases the firmness between the card block 6 and the limiting groove 3, resulting in better stability.

[0034] In the embodiment, the water seepage hole 16 has a smaller diameter than the water drainage hole 15, and the water drainage hole 15 is a tapered hole.

[0035] The water drainage hole 15 with a large diameter makes it easier for the accumulated water to be drained out of the water drainage hole 15, and it is difficult for the water to be drained out of the water seepage hole 16.

[0036] The above is only further embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art within the scope disclosed by the present application, according to the technical scheme and the conception of the present application, makes equivalent replacement or change, all belong to the protection scope of the present application.
