Abstract
An anti-cracking artificial ice rink ice layer belongs to the technical field of structural engineering. It solves the problem that the ice layer of the existing artificial ice rink is easy to crack. An ice layer: the refrigerator consists of a carbon fiber net layer, a refrigerating layer, a carbon fiber net ice layer and an upper ice layer from bottom to top.
