Technical Field

The invention relates to a geothermal floor, in particular to a geothermal floor capable of conducting heat quickly and a production process thereof.

Background

The geothermal floor is heated by floor radiation, the indoor temperature is uniform, the temperature is radiated from the ground to the top and is decreased progressively from the bottom to the top. Since the geothermal floor is subject to a temperature difference of 30 to 50 ℃, the technical indexes of the geothermal floor, such as heat resistance, shrinkage performance, wood density and the like, have higher standards than those of the common floor. The geothermal floor comprises a pure solid wood geothermal floor and a carbonized solid wood geothermal floor. The pure solid wood geothermal floor refers to a solid wood floor which can be directly used in a ground heating (geothermal) environment on the basis of not changing the natural properties of the solid wood floor; the carbonized solid wood geothermal floor carries out high-temperature treatment of hundreds of degrees on wood blanks by high-temperature carbonization, destroys the original structure of wood and naturally deteriorates the comfort after paving. However, since both the pure solid wood flooring and the carbonized solid wood flooring applied to geothermal heating have a thick thickness, the heat transfer rate is slow, and thus the overall heat transfer effect of the geothermal heating flooring is poor. In addition, because the geothermal floor needs to bear the temperature difference of 30-50 ℃, the existing geothermal floor is easy to deform after being used for a period of time. Therefore, the conventional technology has a problem of slow heat conduction speed.
