Fig. 2 is a view showing an embodiment of the suction / moisture-proof wallpaper according to the present invention,
FIG. 3 is a flow chart showing a manufacturing process of the suction / moisture-proof wallpaper according to the present invention,
4 is another embodiment of the suction / moisture-proof wallpaper according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the drawings, the same reference numerals as in the drawings denote the same elements in the drawings, unless they are indicated on other drawings.

FIG. 2 is an embodiment of the suction / moisture proof wallpaper according to the present invention, and FIG. 3 is a flowchart showing a manufacturing process of the suction / moisture proof wallpaper according to the present invention.

2, the suction / moisture barrier wallpaper 100 according to an exemplary embodiment of the present invention includes a base layer 110, a bio-resin layer 120 stacked on the base layer 110, An inorganic binder layer 130 stacked on top of the bio resin layer 120, an inorganic powder layer 140 stacked on the inorganic binder layer 130, And a surface protective layer 150 laminated thereon.

The configuration of the present invention will be described in detail as follows.

The base layer 110 is the most basic layer that holds the curling balance of the wallpaper. The base layer 110 may be made of a nonwoven fabric or a cotton fabric, which is made of a base paper, a pulp and a polyester. Or a ceramic paper or glass paper so as to improve the absorption / desorption efficiency of wallpaper, which is a feature of the present invention.

Preferably, the base layer 110 has a mass per unit area of 60 to 80 g / m 2. If the mass per unit area of the base layer 110 is less than 60 g / m 2, the strength of the wallpaper can not be sufficiently secured. If the mass per unit area of the base layer 110 exceeds 80 g / m 2, There is a problem that the cost of raw materials per area is increased more than necessary.

The bio-resin layer 120 is formed on the base layer 110. The bio-resin layer 120 may be formed of cellulose, chitin, starch, PLA (poly lactic acid) PHA (Polyhydroxy Alkanoate), PHBV (Hydroxy Butyrate Valerate), PVA (Poly Vinyl Alcohol), PGA (Poly Glycolic Acid), PBS (Poly Butylene Adipate), PBA Adipate Terephthalate), Poly Capro Lactone (PCL), Poly (Ester-Amide), and Poly (Ester-Urethane) .

In addition, the bio-resin layer 120 may further include 5 to 20 parts by weight of a nanomineral based on 100 parts by weight of the resin so as to improve heat resistance, moisture resistance, and compatibility between the resins. Preferably, the nanomineral is mica, talc or nano-clay, but the present invention is not limited thereto.

It is preferable that the average size of such nanomaterials is in the range of 1 to 100 nm. In other words, when the size of the nanomineral is less than 1 nm, undesirable aggregation may occur in the bio-resin layer 120, resulting in deterioration of dispersibility. If the size exceeds 100 nm, the performance of the nanomineral may deteriorate .

The inorganic binder layer 130 is made of an inorganic powder layer 140 made of inorganic particles, and the inorganic binder layer 130 is made of an inorganic powder, And acts as an adhesive to adhere to the upper surface of the bio resin layer 120. The inorganic binder layer 130 may be made of at least one selected from inorganic particles such as talc, mica, clay, porous alumina, sodium silicate, and calcium silicate.

The inorganic powder layer 140 is formed as a whole on the upper surface of the bio resin layer 120 through the inorganic binder layer 130, thereby reducing indoor harmful substances and living odors, . Preferably, the inorganic powder layer 140 may include at least one selected from inorganic particles such as talc, mica, clay, porous alumina, sodium silicate, and calcium silicate. The inorganic powder layer 140 is formed using a scattering method, and a natural-friendly design can be realized.

The surface protective layer 150 is laminated on the inorganic powder layer 140, has moisture permeability, and can be coated by a wiping method. Preferably, the surface protection layer 150 is formed by mixing acrylic resin and methyl ethyl ketone at a ratio of 2: 8. The surface protective layer 150 is formed on the upper surface of the inorganic powder layer 140, which is a moisture absorptive and desorptive material, by a surface coating treatment, thereby improving scratch resistance, abrasion resistance and wallpaper durability.

4 is a side cross-sectional view showing an air-impermeable and moisture-proof wallpaper according to another embodiment of the present invention.

Referring to the drawings, an absorbent / moisture barrier wallpaper 100 'according to another embodiment of the present invention is formed by repeatedly layering an inorganic binder layer 130 and an inorganic powder layer 140 on an upper side of a bio resin layer 120 It is possible to improve the moisture absorptive and desorptive function by increasing the amount of the humidifying material.

According to the present invention, the air-impermeable and moisture-impermeable wallpaper 100, 100 'according to the present invention can control humidity by using an eco-friendly material such as a bio resin and an inorganic material and can realize a pleasant indoor environment, Syndrome and the like can be prevented.
