Description

Technical Field

[0001] The present invention belongs to the field of artificial ice materials, and specifically relates to a micron inorganic filler for artificial ice, an artificial artificial ice material comprising the filler, a preparation method of the filler and the artificial artificial ice material, a translucent artificial ice floor surface layer obtained by integrally casting the artificial artificial ice material, and an artificial artificial ice rink comprising the artificial ice floor surface layer. Background Art

[0003] The development of ice sports in high latitudes of the earth has unique natural conditions, and training and competition activities can be carried out on real ice. However, in low-latitude areas, if you want to carry out real ice sports, you need to refrigerate and make ice. The equipment cost and operation cost of ice making are high, which seriously limits the popularity of ice sports. The emergence of artificial ice has changed this situation, making it possible to popularize ice sports in southern my country.

[0004] In 1977, the first artificial ice patent (US4169688) appeared in the United States. The ice rink floor was made of ultra-high molecular weight polyethylene sheets. Since then, ultra-high molecular weight polyethylene has become the mainstream material for artificial ice. Since then, many patent applications have appeared around ultra-high molecular weight polyethylene, mainly focusing on how to splice, lay and modular technology. Although ultra-high molecular weight polyethylene has good wear resistance and lubrication properties, since only splicing technology can be used to form an artificial ice rink, splicing seams will inevitably appear, and changes in ambient temperature will also cause the splicing seams to deform to varying degrees. With the extension of the service life, the resulting splicing deviation will increase year by year. At the same time, this modular splicing process has high requirements for the construction environment and extremely high requirements for the flatness of the laying base surface. The installation procedure is relatively complicated, and professional technicians are required to install and special equipment is required to adjust.

[0005] Among all winter sports, curling is the sport with the highest requirements for the quality of the ice surface and is also the most delicate. Even a temperature difference of 1 degree Celsius or a flatness deviation of 1 mm on the ice surface will affect the performance of athletes. Therefore, it is more difficult to make artificial ice suitable for curling venues. Summary of the invention
