Description

Technical Field

[0001] The utility model relates to the field of sports floors, in particular to a waterproof and impact-resistant sports floor. Background Art

[0002] Sports floors are widely used in the laying of sports stadiums. At present, most sports floors are wooden floors made of wood as the main raw material, but wooden floors have poor waterproof performance and cannot prevent moisture from the board surface from penetrating into the ground. They are also prone to corrosion and have a short service life. In addition, wooden floors have poor impact resistance. Hard objects such as basketball stands and sports equipment can easily cause indentations on the board surface, affecting the service life of the floor.

[0003] Therefore, we need to design a waterproof and impact-resistant sports floor to solve the above problems. Utility Model Content

[0004] Aiming at the problem that the existing sports floor has poor waterproof and impact resistance, the utility model aims to solve the above problems by providing a waterproof and impact-resistant sports floor.

[0005] According to one aspect of the utility model, a waterproof and impact-resistant sports floor is provided, including a substrate, an upper SPC board and a lower SPC board are respectively arranged on the top and bottom surfaces of the substrate, a primer layer is arranged on the top surface of the upper SPC board, a digital painting layer is arranged on the top surface of the primer layer, a topcoat layer is arranged on the top surface of the digital painting layer, and the upper SPC board, the substrate and the lower SPC board are connected to each other by cold-pressed adhesive bonding. The upper SPC board and the lower SPC board of the utility model are made of SPC materials with waterproof and moisture-proof properties, which can effectively prevent moisture on the board surface from seeping onto the ground, and have a good waterproof effect; by respectively arranging the upper SPC board and the lower SPC board on the top and bottom surfaces of the substrate, the impact resistance of the floor can be greatly improved, and the service life of the floor can be effectively improved.

[0006] In some embodiments, the base plate is formed by hot-pressing and gluing multiple layers of solid wood boards in a criss-cross pattern, thereby making the structure of the base plate reasonable and stable, and effectively eliminating the internal stress of the floor and preventing the floor from cracking and deforming.

[0007] In certain embodiments, the primer layer includes an adhesion primer layer and a white primer layer, wherein the adhesion primer layer is applied to the top surface of the upper SPC board, and the white primer layer is applied to the top surface of the adhesion primer layer. Thus, the primer layer can increase the color effect and adhesion of subsequent processes.

[0008] In some embodiments, the adhesion primer layer is a UV adhesion primer layer, and the white primer layer is a UV white primer layer. Thus, the UV adhesion primer layer has good adhesion, and the UV white primer layer has a covering effect, which can avoid color difference caused by uneven color of the upper SPC board.

[0009] In some embodiments, the digital painting layer is sprayed by a six-color digital inkjet printer. Thus, the digital painting layer can spray various patterns by the six-color digital inkjet printer, and can be customized according to customer needs, with rich and varied patterns.

[0010] In some embodiments, the topcoat layer is an anti-skid topcoat layer. Thus, by providing the topcoat layer on the digital painting layer, the digital painting layer can be isolated from the outside world, which can effectively protect the digital painting layer from damage and prevent the board surface from being corroded by moisture, thereby increasing the service life of the floor. The topcoat layer can also improve the anti-skid performance of the floor and prevent athletes from sports injuries.

[0011] In some embodiments, the anti-skid topcoat layer is a high-gloss UV anti-skid topcoat layer. Thus, the high-gloss UV anti-skid topcoat layer has anti-skid and wear-resistant effects, can ensure that the friction coefficient of the floor is about 0.5, and can effectively prevent sports injuries to athletes caused by the floor being too slippery or too astringent.

[0012] In certain embodiments, the substrate has a thickness of 14.6 mm.

[0013] In certain embodiments, the thickness of the upper SPC board and the lower SPC board are both 1.7 mm.

[0014] In some embodiments, the waterproof and impact-resistant sports floor is provided with tongues and grooves around its periphery, and the tongues and grooves are flat buckles or lock buckles. Thus, by providing tongues and grooves around the waterproof and impact-resistant sports floor, the waterproof and impact-resistant sports floor is easy to install and can improve stability after installation.

[0015] The beneficial effects of the utility model are as follows:

[0016] 1. The upper SPC board and the lower SPC board of the utility model are made of SPC material with waterproof and moisture-proof properties, which can effectively prevent moisture on the board surface from seeping into the ground, and have a good waterproof effect; by arranging the upper SPC board and the lower SPC board on the top and bottom surfaces of the base plate respectively, the impact resistance of the floor can be greatly improved, and the service life of the floor can be effectively improved.
