Abstract

The invention discloses an ultrahigh molecular weight polyethylene ice skate blade. The ice skate blade is characterized by being prepared from the following materials in parts by weight: 80 to 100 parts of ultrahigh molecular weight polyethylene, 0.3 to 2 parts of coupling agent, 1 to 3 parts of lubricating agent, 5 to 20 parts of glass microbeads or talcum powder, 0.003 to 0.02 part of fluorescent whitening agent OB, 0.1 to 0.2 part of antioxidant, and 0.2 to 1 part of carbon nanotube, wherein the carbon nanotube has the draw ratio of (800-1000) to 1, and is a multi-wall carbon tube; the ice skate blade is easy to machine and mold, and has superior friction and abrasion performance; by adopting the composition, the heat resistance, impact resistance, weather resistance and size stability are improved, a superior performance cost ratio is achieved, the abrasion resistance is improved greatly, and the application range of an ultrahigh molecular polyethylene material, especially the application on the ice skate blade, is extended greatly.

Description

technical field [0001] The patent of the present invention relates to an ice blade for skating rinks, in particular to an ice blade made of ultra-high molecular weight polyethylene. Background technique [0002] The skate is the knife-like metal object under the skate and is the most important part of the skate. There are three kinds of ball knives, running knives and pattern knives. The blade of the ice skate is very thin, and even the longest speed skate blade has a maximum contact area with the ice surface of less than 10 square centimeters. Therefore, a large pressure is generated on the ice surface during skating, which greatly reduces the melting point of the ice. The ice melts into water, which reduces the friction between the skates and the ice, which is more conducive to the sliding of the skates. The development and progress of figure skating technology is closely related to the gradual improvement of ice skates. It has been found that the oldest ice skates are ...
