The present invention relates to a temperature-sensitive discolored flooring material and a method for manufacturing the same, and more particularly, to a temperature-sensitive color-flooring material and a method for manufacturing the same, which can predict the temperature of the floor in response to a temperature change of the indoor floor.

In general, building flooring is a practical living space for humans, so various functionalities and decoration are required.

Accordingly, the role of flooring, which has conventionally simply finished the floor of a building, has recently been spreading the sophistication, luxury, and personalization of flooring due to the improvement of the living standard of consumers and the improvement of the living living environment. So, companies are producing a variety of functional products such as water-blocking floors, noise-reducing floors, shock-absorbing floors, and far-infrared emitting floors as general and simple products are difficult to survive in competition, but consumers want more functional products. There is a situation.

The flooring material is intended to effectively radiate heat from the heating tube embedded in the indoor floor as well as the indoor interior effect, so as to have an even heating effect not only indoors but also the entire room. However, in the case of indoor heating, the heat dissipation temperature cannot be artificially measured by the user. Therefore, after heating for a certain time, the indoor floor is touched or judged as indoor air. In this case, it is difficult to set an incorrect indoor temperature to create a comfortable indoor environment. it's difficult.

As a conventional technology of functional flooring, Republic of Korea Patent No. 10-0461659 (2004.12.03) discloses 'PVC flooring having the effect that the printed pattern is reversibly changed.' The flooring according to this is for the PVC flooring having the effect that the printed pattern given by using a thermochromic pigment appears or disappears with the change of temperature. However, these PVC floorings are merely the appearance or disappearance of the printed pattern according to the change in temperature, it does not provide heating information according to the temperature change.

On the other hand, as a conventional technology that changes the color depending on the temperature, Republic of Korea Patent No. 10-0354256 (2002.09.12) is published 'the liquid crystal display device that changes the color depending on the temperature'. As a result, the color of the liquid crystal display device varies depending on the temperature due to the cholesteric liquid crystal material and the transparent electrode, but the cholesteric liquid crystal material changes only to the same color irrespective of the high and low calorific value of the electrode. Therefore, it does not provide heating information according to the temperature change.

Therefore, it is necessary to develop flooring materials that provide heating information to users by transforming and displaying flooring materials in different colors in response to temperature changes of indoor floors, eliminating the boredom caused by the use of general-shaped flooring materials, and creating a different indoor atmosphere.
