Hereinafter, the composite multifunctional sheet according to the present invention and a manufacturing method thereof will be described in detail with reference to the accompanying drawings.

The decorative sheet 1 of the present invention shown in FIG. 1 includes a polyvinyl chloride base layer 2, a pattern layer 3 transferred to an upper surface of the polyvinyl chloride base layer 2, and the pattern layer 3 It consists of a surface protective layer (4) formed by coating a polyvinyl chloride film on the upper surface of the. In particular, the decorative sheet (1) of the present invention 15 to 25 mixed layer (5) consisting of an anion-releasing material, a capsule-type fragrance and a silver liquid on the upper surface of the surface protection layer (4) in order to emit aroma and antibacterial action It is formed by coating with a thickness of µm.

Here, the mixed layer 5 comprises an anion releasing material, a capsule-type fragrance and a silver liquid, wherein the anion releasing material is ZrO ₂ , Na ₂ O, which is known as a material which releases a large amount of anions in a natural state. , SiO ₂ , Al ₂ O ₃ , P ₂ O, K ₂ O, MgO and the like are powdered.

In addition, the content ratio of the components constituting the anion-releasing material is 11.9 ~ 15.6% by weight of ZrO ₂ powder, 3.3 ~ 4.1% by weight of Na ₂ O powder, 65.4 ~ 72.9% by weight of SiO ₂ powder, 4.6 ~ 5.8 of Al ₂ O ₃ powder Wt%, P ₂ O powder 2.4-3.0 wt%, K ₂ O powder 1.1-1.3 wt%, MgO powder 3.8-4.8 wt%.

In addition, the capsule-type fragrance is to contain a fragrance component encapsulated in the inside of the capsule produced in the form of a thin film of a soft synthetic resin, such as urea resin or melamine resin.

Therefore, when the decorative sheet 1 of the present invention containing the capsule-like fragrance is attached to the surface of various furniture, the capsule-like fragrance applied to the sheet 1 by friction generated when wiping the furniture. The capsule is destroyed, and thus the fragrance component is volatilized to give off a fragrance. In addition, the decorative sheet 1 of the present invention, since the capsule-type fragrance is applied to the surface of the sheet 1, the amount of fragrance emitted through the sheet is significantly higher than that of the conventional decorative sheet.

In addition, the silver solution is composed of 93 ~ 97% by weight and 3-7% by weight of jade colloidal silver of 99.99% purity, and acts antibacterial with the anion-releasing material. In particular, silver solution has been reported to sterilize about 650 bacteria, above all, silver liquid has the advantage that it is not resistant, unlike ordinary antibiotics, and is extremely safe for children and has no side effects.

Hereinafter, a method of manufacturing the decorative sheet 1 of the present invention in which the mixed layer 5 composed of an anion-releasing material, a capsule-like fragrance, and a silver liquid on the upper surface is described.

First, 11.9 to 15.6% by weight of ZrO ₂ powder, 3.3 to 4.1% by weight of Na ₂ O powder, 65.4 to 72.9% by weight of SiO ₂ powder, 4.6 to 5.8% by weight of Al ₂ O ₃ powder, 2.4 to 3.0% by weight of P ₂ O powder , 50-60% by weight of anion-releasing material consisting of 1.1-1.3% by weight of K ₂ O powder, 3.8-4.8% by weight of MgO powder, 25-30% by weight of capsule-type fragrance containing fragrance ingredient in the capsule, 93-97% of silver 15% to 20% by weight of the silver solution containing 3% to 7% by weight of jade is mixed and accommodated in the container 8.

Here, the different silver liquid contains a predetermined amount of a polyurethane resin, and the polyurethane resin is a paint having a urethane bond (-OCONH-) in the coating film, and includes a polyol component having a large number of OH groups and an isocyanate group (-NCO-). It has a function of forming a coating film by mixing a plurality of crosslinking components just before use to form a urethane bond.

In addition, the temperature of the mixture contained in the vessel 8 should be maintained to be 30 ~ 40 ℃. If the temperature of the mixture falls below 30 ℃ solvent does not fly well during drying, when the temperature of the mixture is more than 40 ℃ problem occurs that the sheet is deformed when applying the mixture to the sheet.

In addition, the mixture contained in the container 8 is buried in the mesh roll 40 and applied to the upper surface of the sheet 1 advancing between the mesh roll 40 and the rubber roll 50. At this time, the mixture is buried in the mesh roll 40 and scraped off with the doctor blade 60.

Here, the angle θ between the doctor blade 60 and the mesh roll 40 is set to 40 to 50 °, and the interval t between the doctor blade 60 and the mesh roll 40 is 0.01 to It should be 0.03mm.

If the angle θ between the doctor blade 60 and the mesh roll 40 is out of the above range, the surface of the mixture deposited on the mesh roll 40 scratched by the doctor blade 60 will not only be smoothed, but also the capsule There is a risk of breaking the capsule of the mold fragrance.

In addition, when the interval t between the doctor blade 60 and the mesh roll 40 is out of the above range, the mixed layer 5 applied to the upper surface of the surface protection layer 4 is out of the thickness of 15 to 25 μm. When the thickness of the mixed layer 5 is greater than or equal to the above range, the anion is released as much and the fragrance is more smelled by the fragrance, but expensive anions and silver solution are consumed, resulting in high manufacturing costs.

In addition, when the thickness of the mixed layer 5 is smaller than the above range, the content of the anion, the silver liquid, and the fragrance is too small, so that the antibacterial action by the anion and the silver liquid and the efficacy of the fragrance by the fragrance are less likely to occur.

In particular, it is more preferable that the angle between the doctor blade 60 and the mesh roll 40 is 45 °, and the distance t between the doctor blade 60 and the mesh roll 40 is 0.02 mm. .

In addition, the rotational sweep of the mesh roll 40 is preferably 20 ~ 30m / min. When the rotational speed of the mesh roll 40 is out of 30 m / min, the mixture in the container 80 is not buried in the mesh roll 40 in an appropriate amount, and the capsule-type fragrance in the process of the mixture being buried in the mesh roll 40. Capsules may be destroyed.
