The present invention relates to a flooring material including an interior layer (100), a middle layer (300), and a backing layer (400) and, more specifically, to a flooring material (10) including: the interior layer (100) having coating layer (110) and a surface printing layer (120); the middle layer (300) having a piezoelectric element layer (310) and a resistant layer (320); and the backing layer (400). The flooring material (10) of the present invention additionally and selectively includes a dimension stable layer (200) between the interior layer (100) and the middle layer (300). The flooring material (10) of the present invention can obtain a heating effect without a separate floor heating even though, in a new building, the flooring material of the present invention is only constructed by autonomously generating heat by converting, into heat energy in a resistant layer (320), electric energy generated in the piezoelectric layer (310) by pressure generated when a person lies down, seats down, or walks, and can remarkably reduce heating energy by constructing the flooring material of the present invention instead of the conventional flooring material in the case of a building in which the floor heating is constructed in advance. Also, the flooring material (10) of the present invention can easily form the piezoelectric element layer (310) and have excellent durability and capacity to resist pressure in comparison with the conventional piezoelectric element made of piezoelectric ceramic by using a polymer resin as matrix of the piezoelectric element layer (310). |
