Description
SHEET PAPER FOR INTERIOR USE AND PREPARING
METHOD THEREOF
Technical Field
[1] The present invention relates to an interior sheet and a production method thereof, and an eco-friendly interior sheet, which comprises either a fabric made of only cotton fiber, or said fabric and a biodegradable natural material deposited thereon, and thus, has natural textures and cubic effects, and does not cause environmental pollution when it is incinerated or buried in landfills, as well as a production method thereof. Background Art
[2] Generally, sheets, for example, non-woven fabrics, are produced from yarns made of organic chemical materials such as polyethylene (PE) resin, polypropylene (PP) resin, polyethylene terephthalate (PET) or the like, or are produced by mixing the organic chemical yarns with grass wool, abaca fiber or hemp yarn at a specific ratio. Alternatively, they are produced by mixing the organic chemical yarns with pulp fiber using a papermaking method, and then adding abaca fiber or hemp fiber thereto. The sheets thus produced are used in various applications, including civil engineering applications, industrial applications, finishing materials for automobiles, and interior finishing materials for buildings.
[3] However, because the prior sheets are based on the organic chemical yarns, the sheets have problems in that they are not recyclable, and when incinerated, emit environmental hormones such as dioxin, harmful to the human body. Also, when the sheets are buried in landfills, they are not biodegradable, and thus cause environmental pollution.

Best Mode for Carrying Out the Invention
[26] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[27] FlG. 1 is a flow diagram showing a process for producing a sheet according to the present invention, and FlG. 2 is a cross-sectional view showing the sheet produced using the process shown in FlG. 1.
[28] As shown in the drawings, in order to produce a sheet 1 according to the present invention, cotton fiber is stored in a first raw material hopper 10. The cotton fiber stored in the first raw hopper 10 is combed in a carding machine 11. The cotton fiber combed in the carding machine is transferred to a first carding machine 12, in which it is spread in the form of thin sheets. Herein, the first carding machine 12 repeatedly moves left and right while it stacks the cotton fiber from the carding machine 11 into a plurality of layers to form a multilayer fabric 3. At this time, the fabric 3 is preferably formed to a thickness of about 0.2-0.6 mm (about 30-120 g/m ), and it is of note that the fabric 3 can be used by itself as a base sheet for wall coverings. [29] Then, any one or a mixture of two or more selected from among biodegradable natural materials, wood flour, chaff powder, green tea powder, mugwort powder, charcoal powder, the compressed and dried stem, leaf, flower leaf, fallen leaf and fallen leaf powder of perennial plants, the leaf of broadleaf trees or needle-leaf trees, perennial hay, thermally expanded vermiculite, flaky mica powder, abaca fiber cut to a specific length, coconut fiber and hemp yarn is deposited on the one surface of the cotton fabric to form a natural material layer 5. Herein, the natural material is transferred from a second raw material hopper through a conveyor 14 to a vibrating screen 15, which then sprays the natural material onto one surface of the cotton fabric in a required amount, preferably 5-150g/m , to form the natural material layer 5 deposited on the fabric 3.
[30] Then, a resin layer 7 made of any one selected from among synthetic resins, acrylic resin, EVE resin and biodegradable EVE resin is formed on one surface of the fabric 3 or on the natural material layer 5. Herein, the resin is diluted with water to a resin solid content of 15-30 wt%, and the diluted resin is sprayed onto the natural material layer 18 through a sprayer and impregnated into the layer 18 through an impregnation system 18. Alternatively, the resin is applied on the natural material layer 5 by injecting air to form bubbles and then pressing the applied resin with a pressing roller (not shown) to reach a resin solid content of 8-25 wt%, thus forming the resin layer 7.
[31] In another embodiment, a fabric 9 can be first deposited on the natural material layer 5 to a thickness of 0.05-0.1 mm using a second carding machine 16, and then the synthetic resin layer 7 can be applied on the fabric 9 in the same manner as described above.
[32] Then, the resulting structure is passed sequentially through a cylindrical dryer 19a and a tunnel-type dryer 19b, thus producing the sheet 1 according to the present invention. The inventive sheet 1 thus produced has an advantage of showing the texture and functionality of natural material, and thus, when the thickness thereof is less than 0.3 mm, it can be used as a lining paper for wall coverings or a base paper for PVC floors.
[33] Also, the inventive sheet 1 thus produced can be used as a wall covering, an interior sheet for automobiles, or an interior finishing material for buildings, through the following steps. [34] FlG. 3 is a cross-sectional view showing a wall covering 30 processed from the sheet 1. First, a first sheet Ia having a thickness of more than 0.4 mm is prepared through the above-described steps. On one surface of the first sheet Ia, i.e., the surface that faces the wall of buildings, a first coating material is applied in an amount of 20-50g/m using a gravure printing method, and the applied coating material is dried to form a first coating layer 31. The first coating material of coating the first coating layer 31 consists of 15-50 wt% of any one or a mixture of two or more selected from among aqueous acrylic resin, aqueous EVA resin, aqueous urethane resin and aqueous biodegradable EVA resin, 0.2-0.5 wt% of any one selected from among non-ionic and anionic dispersants, 15-20 wt% of water, 20-40 wt% of calcium carbonate and/or talc, 0.3-0.5 wt% of any one selected from among silicone- and non-silicone-based defoaming agents, 3-10 wt% of any one selected from among far-infrared-emitting materials, jade, hardwood charcoal, loess, germanium, illite, quartz porphyry and ceramic powder, and anion-emitting selanium, and 11.5-14 wt% of any one selected from methanol and aqueous alcohol.
[35] On the other surface of the first sheet Ia, which is opposite to the first coating layer
31, a printed layer 32 having various patterns is formed using a gravure printing process. On the printed layer 32, a first top coating material of forming a transparent film is applied in an amount of about 20-100 g/m using a rotary screen process, a gravure printing process or a wiping process (a kind of impregnation process), and the applied top coating material is dried to form a first top coating layer 33. The first top coating material of forming the first top coating layer 33 consists of 40-70 wt% of any one any one or a mixture of two or more selected from aqueous acrylic resin, aqueous urethane resin and aqueous melamine resin, 3-5 wt% of silical powder, 6-18 wt% of any one selected from methanol and aqueous alcohol, 5-10 wt% of any one or a mixtu re of two or more selected from polyethylene-, silicone- and Carnauba-based water- soluble waxes, 5-10 wt% of pearlite and/or flaky mica powder, 0.2-0.5 wt% of any one selected from non-ionic and anionic dispersants, 10-15 wt% of paraffin wax, polyethylene wax, silicone-based water repellent and fluorine-based water repellent, 0.5-1 wt% of any one selected from alkaline and acidic inks, and alkaline pigments, and 0.3-0.5 wt% of a defoaming agent.
[36] When the first top coating layer 33 is formed on the printed layer 32, the production of the wall covering 30 from the first sheet Ia is completed. Furthermore, a first aqueous foam composition layer 34 indicated as a dotted line can also be formed on the first top coating layer 33, thereby completing the production of the wall covering Ia from the first sheet Ia. The first aqueous foam composition layer 34 is formed by applying a first aqueous foam composition on the first top coating layer 33 in an amount of about 20-100 g/m (based on solids) using a rotary screen process or a gravure printing process and then drying the applied coating layer. The first aqueous foam composition of forming the first aqueous foam composition layer 34 consists of 10-50 wt% of any one or a mixture of two or more selected from among aqueous acrylic resin, aqueous EVA resin and aqueous urethane resin, 5-10 wt% of water, 32.5-35 wt% of a mixture of two or more selected from among inorganic fillers, calcium carbonate, talc and titanium dioxide, 5-14 wt% of silical powder, 2-8 wt% of any one or a mixture selected from isobutane- and isopentane-based aqueous foaming agents, 3-10 wt% of MEG (monoethylene glycol), 1-10 wt% of pulp powder, 0.2-0.5 wt% of non-ionic, anionic and amphoteric emulsifiers, 0.3-0.5 wt% of any one of non- ionic and anionic dispersants, and 1-2 wt% of any one of alkaline and acidic inks, and basic and alkaline pigments.
[37] Meanwhile, FIG. 4 is a cross-sectional view showing a laminate 40 of two sheets 1 each having a thickness of 0.15-0.4 mm, which is used as a wall covering, an interior sheet for automobiles, and an interior sheet for buildings. First, a second sheet Ib is prepared. On one surface of the second sheet Ib, i.e., the surface facing the wall of buildings and the like, a second coating material having the same composition as that of the first coating material of the first coating material 31 is applied in an amount of about 20-50 g/m (based on solids) using a gravure printing process, and the applied coating material is dried to form a second coating layer 41a. The second coating layer 41a serves to reduce horizontal elasticity caused by heat in the product of products and to reduce the shrinkage of the sheet caused by the water of a glue and adhesive used to attach the sheet on wall surfaces when the sheet is used as a wall covering and a finishing material for buildings.
[38] In another embodiment, a first flame-retardant coating layer 41b can be formed instead of the second coating layer 41 in order to render the sheet flame-retardant. As a flame retardant, aluminum oxide or magnesium hydroxide is used, the first flame- retardant coating layer 41b is formed by applying a first flame-retardant material on one surface of the second sheet Ib in the same manner as the second coating material and drying the applied material. The first flame-coating material of forming the first flame-retardant coating layer 41b consists of any one selected from among 15-50 wt% of aqueous acrylic resin, aqueous EVA resin and aqueous biodegradable EVA resin, 0.2-0.5 wt% of any one selected from among non-ionic and anionic dispersants, 15-20 wt% of water, 22-40 wt% of a mixture of aluminum hydroxide and magnesium hydroxide, 0.3-0.5 wt% of any one selected from among silicone- and non- silicone-based defoaming agents, and 9.5-14 wt% of any one selected from among far- infrared-emitting materials, jade, hardwood charcoal, loess, germanium, illite and quartz porphyry, and anion-emitting selanium.
[39] On the other surface of the second sheet Ib, which is opposite to the second coating layer 41a or the flame-retardant coating layer 41b, an adhesive composition, which can maximize adhesive functions and embossing forming effects is applied in an amount of about 50-150 g/m (based on solids) using a comma coater process or rotary screen process, and the applied composition is dried to form an adhesive composition layer 42a. The adhesive composition of forming the adhesive composition layer 42a consists of 20-50 wt% of any one or a mixture of two or more selected from among aqueous acrylic resin, EVA resin, biodegradable EVA resin, aqueous polyethylene resin and water-soluble rosin resin, 4-10 wt% of water, 0.2-0.5 wt% of any one selected from among anionic and non-ionic dispersants, 2-5 wt% of any one or a mixture selected from among lightweight microcell and microcapsule-type lightweight materials, 36-45 wt% of a mixture of two or more selected from among calcium carbonate, talc and titanium dioxide, 3-5 wt% of silical powder, 2-5 wt% of pulp powder, 1-5 wt% of any or a mixture selected from among isobutene- and isopentane-based aqueous foaming agents, 1.5-4 wt% of MEG (monoethylene glycol), and 0.3-0.5 wt% of a defoaming agent. The adhesive composition layer is made of 95-97 wt% of the adhesive composition and 3-5 wt% of any one selected from among far-infrared-emitting materials, jade, hardwood charcoal, loess, germanium, illite and quartz porphyry, and anion-emitting selanium.
[40] In still another embodiment, a flame-retardant adhesive composition layer 42b can be formed instead of the adhesive composition layer 42a in order to impart flame retardancy to the product. As a flame retardant, aluminum hydroxide or magnesium hydroxide is used, and the flame-retardant adhesive composition layer 42b is formed by applying the flame-retardant adhesive composition on the other surface of the second sheet Ib in the same manner as the adhesive composition and drying the applied composition. The flame-retardant adhesive composition of forming the flame- retardant adhesive composition layer 42b consists of 20-50 wt% of any one or a mixture of two or more selected from among aqueous acrylic resin, aqueous EVA resin, biodegradable EVA resin, aqueous polyethylene resin and water-soluble rosin resin, 4-10 wt% of water, 0.2-0.5 wt% of any one selected from among anionic and non-ionic dispersants, 36-45 wt% of a mixture of aluminum hydroxide and magnesium hydroxide, 3-5 wt% of silical powder, 2-5 wt% of pulp powder, 2-5 wt% of any one or a mixture selected from among lightweight microcell and microcapsule-type lightweight materials, 1-5 wt% of isobutane- and isopentane-based aqueous foaming agents, 1.5-4 wt% of MEG (monoethylene glycol), and 0.3-0.5 wt% of any one selected from among anionic and non-ionic defoaming agents. The flame-retardant adhesive composition layer is made of 95-97 wt% of the composition and 3-5 wt% of any one selected from among far-infrared-emitting materials, jade, hardwood charcoal, loess, germanium, illite and quartz porphyry, and anion-emitting selanium. [41] Then, a second sheet Ic is laminated on the adhesive composition layer 42a or the flame-retardant adhesive composition layer 42b. On the second sheet Ic, a printed layer 43 is formed, and on the printed layer 43, a second top coating composition having the same composition as the first top coating composition of forming the first top coating layer 33 is applied and dried to form a second top coating layer 44. The two sheets 1 are laminated on each other to produce a laminate 40 for use as a wall covering, an interior sheet for automobiles, and a finishing material for buildings. Herein, the second sheet Ic is laid on the adhesive composition layer 42 and dried in a drying oven at a temperature of 180-250 °C for 20-40 seconds, so that it is firmly laminated on the underlying sheet. The second coating layer 44 is formed by applying the second top coating composition in an amount of about 20-100 g/m using a rotary screen process, a gravure printing process and an impregnation process and drying the applied composition.
[42] The embossing of the adhesive composition layer 42 can be carried out before or after forming the second top coating layer 44. In order to maximize embossing effects, the embossing operation is preferably carried out in a state where the surface temperature of engraved embossing rollers reached 50-200 °C by means of heat medium oil, electrically heated rollers or hot water placed in the engraved rollers.
[43] FlG. 5 is a cross-sectional view showing a wall covering 50 processed from the fabric 3 of the sheet 1. First, the fabric 3 made of only cotton fiber is prepared. The prepared fabric 3 has a thickness of 0.3 mm (50-150 g/m2). On one surface of the fabric 3, which faces the wall of buildings, a third coating material having the same composition of the first coating material of forming the first coating layer 31 is applied in an amount of about 20-50 g/m (based on solids) using a gravure printing process, and the applied composition is dried to form a third coating layer 51a.
[44] On the other surface of the fabric 3, which is opposite to the third coating layer 51a, a second aqueous foam composition is applied to a thickness of 0.2-0.5 mm (100-300 g/m based on solids) using a comma coater process or a rotary screen process, thus forming a second aqueous foam composition layer 52a. The second aqueous foam composition is applied on the other surface of the fabric 3, gelled in a drying oven at 180-250 °C for 20-40 seconds (herein, the internal foam state of the aqueous foaming composition becomes a semi-foam state of about 50-70%) and cooled, thus forming the second aqueous foam composition layer 52a. The second aqueous foam composition of forming the second aqueous foam composition layer 52a consists of 10-50 wt% of any one or a mixture selected from among aqueous acrylic resin, aqueous EVA resin and aqueous urethane resin, 5-10 wt% of water, 33.5-40 wt% of a mixture of two or more selected from inorganic fillers, calcium carbonate, talc and titanium dioxide, 5-14 wt% of silica! powder, 2-10 wt% of any one or a mixture selected from among isobutane- and isopentane-based aqueous foaming agents, 3-10 wt% of MEG (monoethylene glycol), 1-5 wt% of pulp powder, 0.2-0.5 wt% of non- ionic, anionic and amphoteric emulsifiers, and 0.3-0.5 wt% of any one selected from non-ionic and anionic dispersants.

Then, the embossing of the third top coating layer 54 is carried out, thus completing the production of the wall covering 50 from the fabric 3.
[46] In order to impart flame retardancy to the wall covering 50, a second flame- retardant coating material 51b having the same composition of the first flame-retardant coating material of forming the first flame-retardant coating layer 41b may be formed instead of the third coating layer 51a to form a second flame-retardant coating layer. Alternatively, an aqueous flame-retardant foam composition can be applied instead of the second aqueous foam composition layer 52a to form an aqueous flame-retardant foam composition layer 52b, thus imparting flame retardancy to the wall covering 50. The aqueous flame-retardant foam composition of forming the aqueous flame-retardant foam composition layer 52b consists of 10-50 wt% of any one or a mixture of two or more selected from among aqueous acrylic resin, aqueous EVA resin and aqueous urethane resin, 5-10 wt% of water, 33.5-40 wt% of a mixture of inorganic fillers, aluminum hydroxide and magnesium hydroxide, 5-14 wt% of silical powder, 2-10 wt% of any one or a mixture of two or more selected from among isobutane- and isopentane-based aqueous foaming agents, 3-10 wt% or MEG (monoethylene glycol), 1-5 wt% of pulp powder, 0.2-0.5 wt% of any one selected from non-ionic, anionic and amphoteric emulsifiers, and 0.3-0.5 wt% of non-ionic and anionic dispersants. The aqueous flame-retardant foam composition is made of 95-97 wt% of the composition and 3-5 wt% of any one selected from among far-infrared-emitting materials, jade, hardwood charcoal, loess, germanium, illite and quartz porphyry, and anion-emitting selanium.
