The TPV (Thermo Plastic Vulcanizate; thermoplastic cross-linked elastomer) resin has excellent insulation, heat resistance, and cold resistance. It refers to a composition containing as a main component.

In general, TPV (Thermo Plastic Vulcanizate; thermoplastic cross-linked elastomer) resins are classified into simple blend-type thermoplastic elastomers (TPO), in which rubber components are simply mixed without any cross-linking components, and partially cross-linked thermoplastics, which are partially cross-linked, depending on the degree of cross-linking of the elastomer. It is classified into a cross-linked elastomer (TPR) and a completely cross-linked thermoplastic cross-linked elastomer (TPV).

In addition, the degree of crosslinking affects the fine dispersibility of the rubber component in the TPV resin, and eventually affects elastic properties such as tensile strength, permanent elongation and compression set. Specifically, in the case of TPO with no crosslinking or TPR with a low degree of crosslinking, there is a limit to converting the rubber phase into a uniform finely dispersed phase due to shear stress. . For this reason, in materials requiring thermoplasticity and excellent elasticity, dynamic crosslinking is performed in which the rubber phase is physically pulverized into fine particles by shear stress during crosslinking.

The Ge-lite is called pozzolan, and contains about 2.0 ppm of germanium and contains a large amount of far-infrared rays and anions, and representative examples include volcanic ash, silicate clay, and silicate.

Copper nanoparticles having a nano size may be used as the copper powder, and the copper nanoparticles may impart antibacterial and deodorant properties. It can impart antibacterial and deodorizing properties, such as removing the cause of an unpleasant odor by interfering with it.

For example, copper oxide nanoparticles may be used as the copper nanoparticles. The copper oxide nanoparticles are surface-modified by stirring 0.1 to 2 parts by weight of silane with respect to 100 parts by weight of copper oxide powder having a particle size of 1 to 200 nm. Copper oxide nanoparticles prepared by the above process may be used.

That is, since the surface of the copper oxide powder is generally hydrophilic, the OH group cannot be dispersed in the resin and can be mutually aggregated. By combining OH groups on the surface of the copper powder through hydrolysis, the hydrophobic OR group in silane is located on the surface of the copper oxide powder, and the dispersibility can be improved due to the repulsive force between the OR groups, that is, between the copper oxide powders.

In addition, the silane is vinyltriethoxysilane, vinyltrimethoxysilane or vinyltri(2-methoxyethoxy)silane to improve dispersibility as described above. silane) may be used, but it is not necessarily limited thereto, and various silanes known in the art may be used.

In addition, the second filter 200 may be inserted and positioned inside the first filter 100 and formed in a cylindrical shape. It can be formed by filling the block 210.

For example, the cypress block 210 may be configured in a hexahedral shape, and a circular hole 220 may be formed to facilitate the flow of air introduced from the outside.

That is, in the second filter 200, the external air passing through the first filter 100 smoothly passes through the circular hole 220 formed in the cypress block 210, thereby reducing the contact area of the contaminated air. It can be widened to promote the purification action, and can perform the purification action of a large amount of outside air.

The cypress block 210 constituting the second filter 200 may be formed of a cypress tree, and the cypress tree ( Chamaecyparis obtusa ) is also called a cypress tree, and is an evergreen tree of the gymnosperm plant Conifer family Cypressaceae, Although it is native to Japan, it is widely cultivated as a plantation species in the southern regions of Korea through development, and is used as a deodorant and antibacterial agent due to the unique scent of cypress trees.

Phytoncide produced in the cypress tree is a self-defense material of plants, and is a material 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.

In addition, phytoncide is known to perform numerous functions such as antibacterial action, deodorant action, sedation action, and stress relief action. In addition, phytoncide cleans and moisturizes the skin with excellent sterilization, antibacterial, and cleansing action, and strengthens the body's immune function.

An antibacterial layer may be formed on the surface of the cypress block 210 constituting the second filter 200 to improve antibacterial and deodorizing properties. It can be formed by drying after application to a surface.

The mint extract may be prepared using leaves and stems of mint. For example, the mint extract prepared by the following method may be used.

In order to prepare the peppermint extract, first, the leaves and stems of the same amount of peppermint are collected, and sodium bicarbonate (NaHCO ₃ ) having a concentration range of 1 to 3 (w/w)% and a temperature of 33 to 37 ° C. is dissolved. Foreign substances attached to the leaves and stems of mint can be removed by washing with purified water for 1 to 5 minutes.

The mint (Mentha arvensis var piperascens) is a perennial succulent plant of the dicotyledonous plant Lamiaceae, which has aromaticity on the plant itself and is upright and branched from the top. The main components of peppermint are alphapinene (+, -), anisaldehyde, Daucosterol, Eugenol, Linalool, Menthone, (+ )-Neomenthol ((+)-Neomenthol) and the like.

Such peppermint emits a refreshing and fresh fragrance, and has bactericidal and antibacterial action against microorganisms such as pathogenic fungi, Escherichia coli, and staphylococcus that cause eczema and scabies existing on the skin or scalp.

In addition, peppermint has the action of constricting the mucous membrane and blood vessels of the skin, paralyzing nerve peripherals, stopping pain, and stopping pruritus, giving the skin a unique refreshing feeling, improving skin diseases, and has a soothing effect on the skin. It is known to have an antioxidant effect, and menthol, the main component of mint, is used medicinally as a liniment, pain reliever, stimulant, or stomachic agent, and is used as a flavoring agent or refreshing agent in toothpaste, candy, jam, cosmetics, cigarettes, etc.

Next, the washed leaves and stems of mint may be steamed with steam.
