Skateboard with brake and manufacturing method thereof

technical field

The invention relates to equipment for sliding sports and a manufacturing method thereof, in particular to a skateboard and a manufacturing method thereof which can be used for skiing, grass skiing, sand skiing and the like.

Background technique

Existing sports skateboards include panels, core boards and bottom boards. In order to make the sliding board light in weight and good in strength, the core board is generally made of low-density lightweight board; in order to reduce sliding friction, the bottom board of the sliding board is made of a layer of low friction coefficient and impact-resistant polyethylene solid sheet; In order to increase the beauty of the skateboard, the surface of the skateboard can be covered with a smooth film or a film with concave and convex patterns printed in various colors. The panel, core board and bottom board are bonded together by heating, rolling and cooling. Yet existing various sports skateboards are not all provided with brake system and steering system, generally all are to rely on the skating skill of the glider or hand-held strut to implement braking and steering. This is not easy for ordinary glider to master, especially when gliding rapidly downward from a high place, it is difficult to effectively control the direction of gliding or brake on the way. This will greatly reduce the fun and safety of skaters playing.

Panel A includes a printed film 1 with patterns printed on it and a foamed upper liner 3 of ethylene vinyl acetate and polyethylene copolymer (EVA+PEpolymer blend), and an upper foamed liner 3 is arranged between the printed film 1 and the upper foamed upper liner 3. There is a new type of ultra-low density metallocene (Metallocen Catalysced) adhesive film4. The composite core board D includes a solid reinforcement board 8 and low density boards 2 respectively arranged on the upper and lower surfaces of the reinforcement board 8, and high density plate 7. The thickness of the composite core board D can be 12-77 millimeters, and wherein each board layer can use any one material in ethylene vinyl acetate (EVA), polyethylene (PE), polypropylene (PP) through hot-melt bonding process or The bonding process of the adhesive film is used for composite production. The thickness and number of layers of the composite core board D can be changed according to the needs of the product. Since the thickness and number of layers of the composite core board D can be selected according to the size and strength requirements of the slide plate, this structure can flexibly adjust the weight and hardness of the slide plate, thereby improving the impact resistance and bending resistance of the slide plate. Increase the service life of the sliding plate.
