If the particle size is less than 50 μm, the pulverization process becomes complex and agglomeration or sedimentation may occur, and if the particle size exceeds 100 μm, moldability may be increased. According to one embodiment, as the base powder material, a mixture of rubber powder and plastic powder in a weight ratio of 1:0.3 to 0.5 may be used.

A mixed powder material may be prepared by mixing the nanocellulose powder, the carbonized cork powder, and the cypress tree powder with the base powder material (S20).

Nanocellulose powder may be used to enhance the mechanical strength of the stopper block 400 . Nanocellulose powder is a variety of wood-derived Kraft paper or sulfurous acid pulp, powdered cellulose ground by high-pressure homogenizer or mill, or refined by chemical treatment such as acid hydrolysis. Microcrystalline cellulose powder, cellulose derived from bacteria, or those derived from plants such as kenaf, hemp, rice, bacchus, and bamboo may be used, but are not limited to the above types. For example, nanocellulose powder may be used having a particle size of 50 to 100 nm.

Carbonized cork powder and cypress tree powder can be used to prevent decay or corrosion of the stopper block 400 through antioxidant, antibacterial, sterilization, etc., along with the toxicity removal or neutralization effect of the composition.

Carbonized cork powder has an air layer formed inside the honeycomb cell structure, so it has excellent humidity control and deodorization effects, so it has excellent moisture-proof, sound-proof and heat-insulating properties. In particular, carbonized cork, unlike general cork, emits far-infrared rays and negative ions to remove the spore roots of bacteria and fungi, thereby suppressing the proliferation of pathogens. In addition, it is light enough to float on water, does not rot, and is not deformed by humidity. Carbonized cork grains contain the unique scent of oak and are 100% biodegradable, a natural raw material that can be reused semi-permanently.

For example, after burning the wood fragments of the inner bark of the cork tree (oak tree), which consists of a hexagonal honeycomb cell structure, it is finely pulverized and compressed, and then heated again in an electric furnace to kill the sap and harmful bacteria contained in the wood. is removed to make a carbonized cork material in the form of a board or block. Thereafter, the material in the form of a board or block may be finely pulverized to produce granular carbonized cork powder having a particle size of 0.5 to 1 mm.

Cypress (Chamaecyparis obtusa), also called cypress, is an evergreen tree of the gymnosperm coniferous Arborvitae family. It is native to Japan, but is widely cultivated as an afforestation species in the southern regions of Korea through development. , is used as an antibacterial agent. Phytoncide produced in cypress trees is a self-defense substance of plants, and is a substance emitted or secreted by plants to resist pathogens, pests, molds, etc., and contains sterilization and insecticidal components in itself. The constituents of phytoncide are organic compounds composed of terpenes, phenolic compounds, alkaloids, glycosides, etc., and are known to have antibacterial, sedative, deodorizing, and stress relieving effects. These phytoncides are natural substances, not chemically synthesized substances, are easily absorbed by the human body, and selectively sterilize bacteria harmful to humans.

According to one embodiment, the mixed powder material may be prepared to include 1 to 5 parts by weight of nanocellulose powder, 5 to 10 parts by weight of carbonized cork powder, and 5 to 10 parts by weight of cypress wood powder per 100 parts by weight of the base powder material. As the mixed powder materials are mixed in the above content ratio, the mechanical strength of the stopper block 400 is enhanced, and elasticity and weather resistance such as decay or corrosion prevention can be effectively secured.

A scent-diffusing functional mixture including a nanoparticle mixture including silver nanoparticles and copper nanoparticles, an antibacterial scent-balancing liquid containing phytoncide stock solution, cedar tree sap, wood vinegar, and moutan bark extract, and a natural oil mixture can be prepared (S30).

The scent-diffusing functional mixture can be used to perform a function of scent-diffusing odors that insects avoid, and can be made of a material to increase the durability of the scent-diffusing function and minimize deterioration of scent.
