The present invention relates to an additive for an environment-friendly finishing material for a building, a finishing material composition including the same, and an environment-friendly finishing material for a building. According to the present invention, the additive for the environment-friendly finishing material for a building is prepared by plaster, activated carbon, jade powder, adsorption deodorant, carbon nanotube-graphene complex, and nano-silica. The activated carbon powder is prepared through the following steps of: cutting each of a bamboo, an oak tree, and a pine tree in the length of 500 to 1,000 mm; carbonizing, at 1,000 to 1,500 °C, each of the bamboo, the oak tree, and the pine tree, which have been cut, to prepare the activated carbon; sorting and separating the carbonized activated carbon; and crushing each of the separated activated carbon to sort the crushed active carbon by a grain diameter in a range of 50-250 mesh. The adsorption deodorant is composed of an electron-ray graft which is obtained by polymerizing diatomite, zeolite, adsorbent, gelite, and an alginic acid, and the carbon nanotube-graphene complex is prepared by inputting carbon nanotubes and graphene powder into a rotary furnace heated at 700 °C and then stirring the resultant. Through the above-described configuration, according to the present invention, moisture can be rapidly evaporated by the plaster during coagulation at the beginning of curing and thus reduce a coagulation speed; in a drying process after coagulation, a drying time can be delayed by continuously supplying water from the activated carbon or adsorption deodorant to prevent a floor or a wall surface of the building from being cracked due to rapid drying; curing time can be adjusted to achieve desired compressive strength; wear resistance, chemical resistance, and surface strength can be improved; and health of a builder and a user can be promoted and a pleasant environment can be achieved. |
