Description
Technical Field
The invention relates to the technical field of sports equipment, in particular to a porous composite material for a bottom of a high mountain snowboard and a processing method thereof.
Background
Sports equipment is a key element in the development of competitive sports activities. The cross-country skiing project is sports with the help of instruments in a specific environment, in recent years, along with the increasing of the technological content of professional equipment, the selection of related devices such as snowboards, snow sticks and snow wax and auxiliary products greatly influences the competition performance of athletes, and the timely introduction and absorption of related scientific research results become one of the key factors for improving the sports performance of the snowy project and preventing injuries. Research related to sports science has shown that the use of high performance snowboards has become an important factor in winning competitions. The adverse factors of China lacking in related research on the high-performance snowboards become fundamental bottlenecks restricting the rapid development of the project, so that the forward pace of research and development of related materials of the high-performance snowboards is accelerated, the foundation of the project development can be tamped, and the strong promotion can be provided for the benign development of the cross-country skiing project.
The traditional base material of the snowboard is prepared by extruding or sintering polyethylene materials. The bottom of the extrusion plate is made of polyethylene particle materials which are melted at a very high temperature and then are pressed to a proper thickness by a machine, and finally a completely flat polyethylene whole body is formed. The sintered plate bottom is also made of polyethylene, and the polyethylene particles are directly extruded by extremely high pressure, so that a whole body is connected together, and the whole plate bottom contains a large number of small air holes. The conventional snowboard bottom needs to be waxed to provide good lubrication during use. Although the sintered plate bottom is an ideal wax adhesion material compared with the extruded plate bottom due to the porous structure, the adhesion of the snow wax is limited, and the snow wax on the surface layer is gradually consumed in the sliding process, thereby influencing the sliding speed of the snow plate. On the other hand, the wear of the polyethylene in the sliding process enables the texture on the bottom surface of the plate to be shallow and even disappear, and the resistance-reducing and pollution-discharging effects of texture treatment are reduced.
Aiming at the problems of the existing snowboard bottom material, the invention provides a snowboard bottom material prepared by using ultra-high molecular weight polyethylene with excellent wear resistance as a board bottom base material, using porous oil storage particles and a two-dimensional material as additives and adopting a sintering method. According to the plate bottom material provided by the invention, the porous oil storage particles automatically release the lubricant in the sliding process, the lubricant and the two-dimensional material play a lubricating role together, the lubricating role is ensured in the whole sliding process, and the limitation of a product using snow wax alone is effectively avoided.
