Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing the first embodiment of the present invention, and FIG. 2 is a sectional view thereof. As shown in the figure, the surface film 120 and the backing film 130 are laminated on the upper and lower surfaces of a buffer sheet 110 formed of a material having a buffering property, and on the upper surface thereof, embossing And an environment mat 100 on which protrusions 112 are formed.

The buffer sheet 110 is made of a synthetic resin foam. The type of the synthetic resin foam that can be used is not particularly limited, but it is made of a synthetic resin foam of the same type as the resin used for the surface film 120 and the back film 120 Good adhesion to the paper surface, the surface film 120 and the backing film 120, and good recyclability. Therefore, the buffer sheet 110 preferably comprises a polyolefin-based foam.

The surface film 120 and the backing film 130 are made of a functional film composition containing a functional component in a polyolefin resin.

The functional ingredient is for imparting antibacterial and deodorizing functions to the surface film 120 and the back film 130, and is composed of titanium dioxide, tourmaline, silver-zeolite and nano-antibacterial liposome.

Titanium dioxide is a typical photocatalyst material and has a strong oxidizing and reducing power, and various organic substances are decomposed and sterilized by the oxidizing and reducing power to have an air purifying, sterilizing and deodorizing effect.

Tourmaline is an active rare earth ore, has antibacterial effect, and releases a large amount of anions.

Also, silver-zeolite is adsorbed to the pores of the nano-silver zeolite. As the nano silver is adsorbed to the pores of the zeolite, the surface area of silver is increased, so that the antimicrobial effect by silver is increased. In addition, antimicrobial effects can also be obtained by zeolite used as a carrier. These silver-zeolites are prepared by impregnating zeolite powder with silver nano-water mixed with silver nano-water.

On the other hand, the nano-antibacterial liposome is an organic antimicrobial substance incorporated into lecithin.

In general, the inorganic antibacterial agent has a persistence of antibacterial power and has a high stability against heat, but it has a disadvantage that its immediate effect of antibacterial activity is weak and its mechanical properties and color of final product are greatly influenced.

On the other hand, the organic antimicrobial agent has an advantage of being excellent in the immediate effect of the antibacterial power, having a wide range of antibacterial power, and not having a great influence on the mechanical properties and color of the final product, but has a disadvantage that the persistence of the antibacterial power is weak.

Since inorganic and organic antibacterial agents have different strengths and weaknesses and different types of antimicrobial strains, inorganic antibacterial agents and organic antibacterial agents must be properly mixed.

Therefore, in the present invention, the inorganic antimicrobial agent (organic antimicrobial substance) and the organic antimicrobial agent (organic antimicrobial substance) are used together. In order to compensate for the disadvantage of the organic antimicrobial substance, the organic antimicrobial substance is introduced into lecithin Nano-antibacterial liposomes are used.

Preferably, a natural antimicrobial substance is used as the organic antimicrobial substance. The natural antimicrobial material that can be used is not particularly limited, but preferably one or more of Perilla frutescens extract, Grapefruit seed extract, Terpene and the like are used.

Especially, Leaf lily extract is an extract of methanol extract of leaf of Perilla frutescens var. Acuta Kudo. Lobules are often perennial herbaceous plants, similar to perilla, belonging to the family Lamiaceae, called lobster. Since the self-leaf extract has excellent antimicrobial effect and particularly excellent antimicrobial effect against food poisoning bacteria, it is preferable to use the self-leaf extract as a natural antimicrobial substance.

The nano-antibacterial liposome is prepared by a known nano-encapsulation method. Specifically, lecithin, alcohol, and the natural antimicrobial materials are mixed with purified water, emulsified using an emulsifier, passed through a high-pressure micro- . Preferably, 1 to 5 parts by weight of lecithin, 10 to 50 parts by weight of alcohol and 25 to 30 parts by weight of natural antibacterial substance are mixed with 100 parts by weight of purified water.

The nano-antibacterial liposomes thus produced have antimicrobial activity persisted because the antimicrobial substances contained in lecithin are slowly released to exhibit antibacterial activity.

Preferably, the functional film composition for forming the surface film 120 and the backing film 130 comprises 0.5 to 5 parts by weight of titanium dioxide, 0.2 to 3 parts by weight of tourmaline, 3 to 7 parts by weight of silver-zeolite with respect to 100 parts by weight of the polyolefin- 0.2 to 5 parts by weight of a nano-antibacterial liposome, 1 to 5 parts by weight of an antioxidant and 1 to 3 parts by weight of a lubricant and the surface film 120 and the backing film 130 are subjected to T-die extrusion And then extruded by a public method or a calendering method.

A surface film 120 and a backing film 130 are laminated on the upper and lower surfaces of a previously manufactured buffer sheet 110, And passes between the pair of heating rollers to bond the surface film 120 and the backing film 130 to the buffer sheet 110. [

The embossing protrusion 112 is formed on the upper surface of the environmental mat 100 to prevent slippage from being formed on the heating roller in contact with the surface film 120. [ do. Preferably, such an environmental mat 100 is manufactured to have a thickness of about 1 to 2 mm.

In order to test the physical properties of the environmental mat 100 according to the present embodiment, the environmental mat 100 is manufactured as described above, and the surface film 120 and the back surface film 130 are coated with 100 parts by weight of a polyethylene resin , A functional film composition comprising 3 parts by weight of titanium dioxide, 1.5 parts by weight of tourmaline, 3 parts by weight of silver-zeolite, 3 parts by weight of nano-antibacterial liposome, 5 parts by weight of antioxidant and 3 parts by weight of lubricant.

5 parts by weight of lecithin, 30 parts by weight of alcohol and 30 parts by weight of natural antimicrobial substance were prepared by nanocapsulation with respect to 100 parts by weight of purified water, and the natural antimicrobial substance was a self-leaf extract, a grapefruit seed extract, Were mixed in the same weight and used.

As shown in Table 2, Table 3, and Table 4, the environmental mats 100 thus prepared were cut into a size of 10 x 10 mm to produce test pieces, and the antibacterial and deodorizing powers were tested. , It has been confirmed that it has excellent antibacterial and deodorizing power.

The present invention having such a constitution is cut into an appropriate size and laid on a drawer of kitchen furniture or a vegetable case of a refrigerator. When used in this way, it is possible to hygienically store kitchen utensils and food materials by the antimicrobial effect of the present invention, , The smell generated from the drawer or the refrigerator is also removed, so that a pleasant kitchen environment can be created. In addition, when a tableware or cooking utensil is stored, the embroidery protrusions 112 prevent the utensils or the cooking utensil from slipping and being damaged by mutual collision.

Hereinafter, other embodiments of the present invention will be described, and the same configurations and effects as those of the above-described embodiments will not be described.

3 to 4 show a second embodiment of the present invention.

3 is a bottom view of the environment mat 100 according to the present embodiment. FIG. 4 is a cross-sectional view. As shown in FIG. 3, a nonslip pattern 140 is printed on the bottom surface of the backing film 130.

This non-slip pattern 140 is intended to keep the environment mat 100 in an initially installed state without slipping and flowing in a drawer or vegetable case. A protrusion similar to the embossing protrusion 112 may be formed on the backing film 130 to improve the frictional force of the backing film 130. If the anti-slip pattern 140 having a large frictional force is formed as in the present embodiment, The frictional force between the environment mat 100 and the bottom surface is more effectively increased as compared with the case where the protrusions are formed on the surface mat 130.

This anti-slip pattern is composed of 25 parts by weight of acrylic acid, 25 parts by weight of triethylamine, 50 parts by weight of styrene butadiene rubber latex, 30 parts by weight of ammonium stearate, 25 parts by weight of rosin and 100 parts by weight of anti- Is printed by a method such as silk screen printing.

In such compositions, cellulose and acrylic acid are the basic binder components of the composition. And triethylamine is used to increase the viscosity of acrylic acid, and styrene butadiene rubber latex improves the friction force with adhesion of the composition. Ammonium stearate is a dispersant, and rosin is an increasing agent.

The anti-slip pattern 140 is coated in a dot or lattice pattern so that the back side film 130 having antibacterial and deodorizing properties is exposed to the outside without being covered by the anti-slip pattern 140, The antibacterial and deodorizing effect by the microorganism is not reduced.

5 and 6 show a third embodiment of the present invention.

As shown in FIG. 5, an aluminum film 150 is further provided between the buffering sheet 110 and the backing film 130 in this embodiment.

The aluminum film 150 is for imparting shape retention to the environment mat 100. That is, since the environmental mat 100 has the shape-retaining property by the aluminum film 150, it is possible to fold and use the environmental mat 100 in a three-dimensional form.

6, the environmental mat 100 may be folded and folded in a form corresponding to the drawer or the refrigerator vegetable case 2. The environmental mats 100 may be folded back and forth, The connection part between the side wall and the side wall is folded outward, and then the outer side of the neighboring side wall is brought into close contact with the connection part.

When the square type environmental mat 100 is folded in this manner, there is no gap between neighboring side wall portions, so that moisture or foreign matter generated from vegetables or fruits in the process of storing vegetables or fruits falls into the vegetable case Therefore, it is convenient to remove only the environmental mat 100 when cleaning, and it is not necessary to clean the vegetable case 2 separately.

The environmental mats 100 may be cut into a shape having a bottom wall and a side wall protruding from the bottom wall. The side wall may be formed with a flap for connecting the neighboring side wall and a fitting hole for fitting the flap, It is also possible to use the folding device 100 in the form of a box. However, in this case, because there is a gap between the side wall part and the side wall part, water or foreign matter discharged from vegetables or fruits falls into the vegetable case through the gap, and thus when the environment mat 100 is removed from the vegetable case Next, it is inconvenient to use because it needs to remove moisture and foreign matter from the vegetable case.

On the other hand, another metal film may be used, but the advantage that the weight of the environmental mat 100 is not greatly increased when lightweight aluminum is used compared to other metals
