Hereinafter, an eco-friendly finishing material composition according to the present invention will be described in detail with reference to the accompanying drawings. Unless otherwise defined, all terms in this specification are the same as the general meaning of the terms understood by those of ordinary skill in the art to which the present invention belongs, and in case of conflict with the meaning of terms used herein, In accordance with the definitions used in the specification. In addition, detailed descriptions of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted. Throughout the specification, when a part "includes" a certain component, it means that other components may be further included rather than excluding other components unless specifically stated to the contrary.

The eco-friendly finishing material composition according to an embodiment of the present invention includes 100 parts by weight of plant fiber, 1 to 2 parts by weight of graphene powder, and 10 to 20 parts by weight of starch. The eco-friendly finishing material composition is mixed with water and applied and dried on the inner wall, floor, and outer surface of the sculpture, and is used as a finishing material for buildings and sculptures.

The plant fiber is a main component of the eco-friendly finishing composition, and fibers obtained from conventional plants may be used, for example, mulberry pulp or mulberry powder. The oak tree is a deciduous broad-leaved shrub of the dicotyledonous plant Nettle tree Morus family, and in the case of a finishing material using plant fibers such as the oak tree fiber, it is known to absorb volatile organic compounds and absorb noise.

The graphene powder is configured to increase the thermal conductivity of the finishing material composition, and the graphene powder may be a commercially available graphene nanopowder, and 1 to 2 parts by weight relative to 100 parts by weight of plant fiber is preferably used.

The starch is used as a binder for the finishing material composition, and the starch is preferably used in an amount of 10 to 20 parts by weight based on 100 parts by weight of plant fibers.

Finishing material composition according to another embodiment of the present invention is 10 to 20 parts by weight of lacquer, 5 to 10 parts by weight of rosin, 0.1 to 0.3 parts by weight of nano diamond, 1 to 2 parts by weight of shell powder, 0.1 to 0.2 parts by weight of pearl vinegar extract, Addition of 0.1 to 0.2 parts by weight of agaric agar extract, 0.1 to 0.2 parts by weight of auditory extract, 0.1 to 0.2 parts by weight of stony extract, 0.1 to 0.2 parts by weight of narcissus extract, 0.01 to 0.03 parts by weight of platinum powder and 1 to 2 parts by weight of persimmon shell extract Include.

The lacquer is a configuration that improves the strength and scratch resistance of the finishing material formed by applying and drying the finishing material composition, and the lacquer is preferably used in 10 to 20 parts by weight based on 100 parts by weight of plant fiber. When the lacquer juice collected from lacquer is used directly, the color of the prepared finishing material changes to a dark color over time, deteriorating the aesthetics of the finishing material, and deteriorating the applicability due to the high viscosity. To solve this, lacquer extract is used. The lacquer extract is mixed with acetone and stirred to form an lacquer solution, and the lacquer solution is allowed to stand for a certain period of time to separate layers into a part that is soluble in acetone and a part that does not dissolve, and then dissolved in acetone. It is obtained by separating the supernatant, which is a part, and evaporating under reduced pressure to remove acetone. When the lacquer solution is allowed to stand for a certain period of time, it is separated into a supernatant layer on the upper side, which is a part soluble in acetone, and a sediment layer on the lower side, in a powder form, which is a part that is not soluble in acetone. As described above, since the present invention uses lacquer extract rather than lacquer, it is possible to lower the viscosity to improve the applicability and prevent the color from changing to a dark color over time.

The rosin is a configuration to improve the adhesive strength of the finish composition and the strength of the finish formed by coating and drying, the rosin is preferably used in 5 to 10 parts by weight compared to 100 parts by weight of plant fiber. When the resin collected from pine is used directly, the color of the finished finishing material composition changes to black over time, deteriorating the aesthetics of the finishing material and deteriorating the applicability due to the high viscosity. To solve the problem, pine extract is used. The rosin extract is obtained by distilling rosin collected from pine trees. As described above, since the present invention uses a rosin extract, not rosin, it is possible to reduce the viscosity to improve coating properties and prevent the color from turning black even after time. In the case of preparing a finishing material composition using the plant fiber and starch, the adhesive strength of the prepared composition decreases, and the strength and scratch resistance of the finishing material formed using the composition decrease. In the present invention, the lacquer extract and the rosin extract It is further mixed to increase the adhesive strength of the composition and improve the strength and scratch resistance of the formed finish, while preventing the coating property from being impaired and the color of the composition from darkening.

The nano-diamond is configured to have a uniform temperature over the entire finishing material formed by applying and drying the finishing material composition, and the nano-diamond is preferably used in an amount of 0.1 to 0.3 parts by weight based on 100 parts by weight of the plant fiber. The thermal conductivity of the finishing material can be increased by using a lot of the graphene powder, but since the color of the composition becomes dark when a lot of graphene powder is used, a small amount of nano-sized nano-diamonds having high thermal conductivity are mixed compared to the graphene powder. By doing so, the thermal conductivity of the formed finish material is increased without darkening the color of the composition.

The shell powder is a configuration to improve the strength of the finish formed by applying and drying the finish composition, the shell powder is preferably used 1 to 2 parts by weight compared to 100 parts by weight of the plant fiber. The shell powder may be, for example, a powder obtained by grinding oysters.

The pearl vinegar extract, agaricaceae extract, auditory extract, dolphinarium extract and narcissus extract are configured to prevent decay of the finishing material composition, and the pearlescent vinegar extract, walnut agaric extract, auditory extract, dolphinarium extract and narcissus extract each 100 weights of the plant fiber It is preferable to use 0.1 to 0.2 parts by weight based on parts. Since the finishing material composition uses vegetable fibers as the main component, the composition may easily spoil over time and have a bad smell.However, when using mineral powder as in the prior art, there is a problem of lowering the strength of the finishing material. By using the extract extracted from the silver plant, the plant fibers are prevented from being easily decayed.

The platinum powder is a composition for preventing spoilage of the finishing material composition, and the platinum powder may be commercially available platinum nanopowder, and it is preferable that 0.01 to 0.03 parts by weight is used based on 100 parts by weight of plant fiber.

The persimmon peel extract is a configuration added to increase the waterproofness of the finish formed by applying and drying the finish composition, the persimmon extract is preferably used 1 to 2 parts by weight compared to 100 parts by weight of the plant fiber. The persimmon peel extract is obtained by immersing the powder obtained by drying the peel of persimmon in ethanol, maintaining at a certain temperature for a certain period of time, removing ingredients through filtration, concentrating the filtrate under reduced pressure, and freeze-drying. If you use less-ripe green persimmons than ripe persimmons, the waterproofness can be further improved.
