The present invention relates to a thermochromic wallpaper and a method of manufacturing the same, and in particular, to provide a wallpaper that changes color in response to a change in the ambient or human body temperature, to provide information on the ambient temperature or the health state of the human body as well as visual The present invention relates to a thermochromic wallpaper capable of removing boredom and a method of manufacturing the same.

In general, wallpapers (also called 'wallpapers') were intended to prevent direct contact between residents and household goods by contacting concrete surfaces by covering concrete surfaces of early buildings. In order to achieve aesthetic effect or high quality in simple wallpapers, synthetic resin materials containing various chemicals are applied to the surface of the wallpaper, and then various types of figures or pictures are printed on the surface to manufacture wallpapers.

Referring to the process for producing such a conventional wallpaper, as shown in Figure 1, the base paper 1 wound in the form of a roll is coated with a liquid resin on the surface of the base paper 10 in the coating step (S1) To obtain a resin coated wallpaper.

And, in the mixing step (S2) based on the raw material resin (DOP: Diocty1 Phthalate), viscosity reducing agent (VS-2025: Viscosity), secondary plastic material (DOP: Di Odorless Pliasticizer), stabilizer (BZ-806P: Barium-Zinc), Titanium Dioxide, light coal (stone powder), blowing agent, zinc oxide, etc. are blended in an appropriate ratio to obtain a mixed liquid resin to be in a sol state.

Then, the mixing of the liquid resin is completed in the mixing step (S2) in the mixing step for a predetermined time in the mixing operation to maintain the particles of each material evenly, the mixed liquid resin on the surface of the paper supplied separately in the coating step It is applied to form a coating layer with a predetermined thickness.

Subsequently, when the application is complete, the liquid resin coated on the surface of the paper to be transferred using the dryer in the drying and printing step (S3) (S4) is dried to coagulate, and at the same time, the resin solidified by the dryer is forced to Allowed to cool and dried to cure.

Then, the resin is cured base paper is supplied to the printing machine so that various figures and drawings are printed on the surface of the resin, and when the drying and printing step (S3) (S4) is completed, heat is heated in the heating step (S5) By heating, the coated resin is foamed to have a thickness of about 1 to 2 mm.

Then, the base paper after the heating step (S5) is fed to the mold pressure step (S6) to be embossed in various forms by a pressure roller for pressing the resin.

Subsequently, the base paper on which the embossing is formed on the resin is cut at both ends by the primary cutter in the cutting step (S7), and then the wallpapers wound by the secondary cutter are cut to an appropriate length and then wrapped (S8). Ship through.

Wallpapers completed through such a manufacturing process is coated with a resin embossed on the surface of the base paper, the various figures and pictures are printed on the surface of the resin.

However, the conventional wallpapers manufactured as described above can achieve aesthetics of the interior or high quality by expressing figures or pictures on the surface of the paper, but as the expressed figures or pictures always have the same color, The user easily felt bored and often used wallpaper by replacing it, which caused a burden on the household.
