Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a functional embossing interior sheet,

The present invention relates to a functional embossing interior sheet and a method of manufacturing the functional embossing interior sheet. More particularly, the present invention relates to a functional embossing interior sheet having a deodorizing effect such as odor, harmful substances, heavy metals, Sheet and a method for producing the same.

Of all the odorous ingredients, it is formaldehyde, which is known to cause bad physical condition and health damage. As new buildings such as houses, office buildings and commercial facilities are constructed, the damage caused by formaldehyde (sick house syndrome) from construction materials, paints, adhesives, and furniture is becoming very serious. In this background, there is a strong demand from the market for the function of improving the comfort of the space such as home, workplace, and automobile. In addition to harmful substances, odor, dust, BACKGROUND ART [0002] Air purification apparatuses for the purpose of eliminating the smell of a pet, living odor, and the like are spreading. Thus, the demand for air purification is increasing, and the tendency of downsizing and lighter weight is getting stronger while maintaining deodorization performance.

Sick building syndrome is caused by indoor air pollution caused by harmful volatile substances such as building materials, furniture, and household goods when moving in after new construction and remodeling and interior construction, causing eye sickness, sore throat, headache, asthma, atopic dermatitis Is a symptom that causes health damage. Representative materials are volatile organic compounds (TVOCs) including formaldehyde (HCHO, Formaldehyde). For example, formalin, which is a mixture of formaldehyde and water, is widely used as an adhesive for interior finishing materials such as plywood, flooring, Respiration of the inhabitants of the room, skin absorption, etc., cause dermatitis, allergies, vomiting, cough, pneumonia, central nervous disorders and the like.

Recently, new car syndrome has emerged as a social issue along with sick house syndrome. The interior of the car is made of plastic so that there is no unused portion of the plastic, and all of the dashboards, sheets, ceilings, floors, floor mats, and so on are organic compounds, and one of its main ingredients, formaldehyde, It is acceptable. In other words, there are problems such as irritating odor inside the car due to formaldehyde which is a toxic substance coming from the tea lumber, feeling headache such as eye stinging, nausea, dizziness, etc. However, The interior space, such as newly constructed houses and buildings, emits indoor pollutants such as formaldehyde and other particles, stimulating the eyes, nose and throat of the human body, causing headaches and dizziness, Allergic diseases such as asthma, rhinitis and atopy are induced.

Accordingly, various measures for reducing the above-mentioned damage have been proposed. For example, there are a method of removing harmful substances as a cause through ventilation or air purification products, and a method of replacing building materials with eco-friendly materials containing no harmful substances Is being used. However, the ventilation or air purification device is a post-treatment method for quickly removing harmful components that have already occurred, not preventing the generation of a chemical component, which is a practical cause, and thus, removing harmful components through ventilation or the like In addition, it takes a long time, and products for air purification can not be a fundamental measure because the removal efficiency for the unit area is not good.

Generally, for the effect of insulation, sound insulation, etc., a thermal insulation material is installed inside the wall of the building structure. Insulation material refers to a material that covers the outside of a part to be kept at a constant temperature and reduces heat loss or heat input to the outside. It is used as insulation for a non-industrial building structure such as fireproof insulation, , Expanded polystyrene, foamed products such as urethane foam, and the like. Among various kinds of insulation materials, it is inexpensive and light and is widely used as an insulation material for general buildings. Expanded polystyrene, also called 'styrofoam', is a product made by expanding polystyrene by the action of a foaming agent. It is white and light, and has water resistance, heat insulation, It is widely used not only as a thermal insulation material for buildings but also as a transportation packing material. However, it releases toxic gas when a fire occurs and is harmful to the human body when it is inhaled. There is a problem.

In order to solve the above-mentioned problems, the present invention provides an embossing layer having a wide surface area as well as providing insulation, soundproofing and cushioning by using an interior sheet including an embossing layer, Which can remove heavy metals and the like, and a method for producing the same.

The adhesive layer of the present invention is formed by applying an adhesive to an embossing layer, and adhering the adsorption layer to the embossing layer.

The adhesive of the present invention is preferably selected from the group consisting of polyvinyl alcohol, polyethylene glycol, methylcellulose, ethylcellulose, water-soluble acrylic resin, water-dispersible urethane resin and starch adhesive, but is not limited thereto.

The present invention can be used by diluting the adhesive in a solvent. It is preferable that the adhesive solution containing the adhesive is diluted in the range of 2.5 to 25% by weight to have a sufficient adhesive strength and can be coated.

The method of coating the adhesive on the surface of the embossing layer of the present invention can be selected from a method of dispersing or coating the adhesive with a spray, a method of adhering or fixing the adhesive in a uniform outer layer type, a method of adhering in the form of a film, In the invention, a method of spraying the adhesive solution onto the surface of the embossing layer is preferable, but not limited thereto.

The embossing layer of the present invention may be an air cap sheet made of a thermoplastic resin, but is not limited thereto. The material of the air cap sheet is not particularly limited. Preferably, it is a polymer capable of film forming with a thermoplastic resin.

The embossing layer of the present invention imparts a sense of cushioning and improves heat insulation and soundproofing performance. Here, preferably, an air cap sheet can be used, but the present invention is not limited thereto. The air-cap sheet includes a plurality of air-cap sheets sealed together by sandwiching two or more films together. For example, air is mainly injected between two polyethylene films, and the air is compressed and fused. Alternatively, the outer film and the inner film may be fusion-bonded to each other in a certain shape and at a constant interval in the air cap, but the present invention is not limited thereto.

In addition, the air-cap sheet is widely used as an easy product for alleviating external impacts, and the air layer formed in the embossed film lowers the thermal conductivity and sticks to the window, which is a product that has been widely recognized as an excellent heat insulating material. In general, there are two general types of air-cap sheet and a heat-insulating air-cap sheet. The difference is that the heat-insulating air-cap sheet has a film on the upper and lower sides of the round air- Section. As a specific example of the present invention, when the adsorption layer is applied to a general air cap sheet, the surface area is widened due to the convex surface, so that a large amount of harmful substances stay in the adsorption layer for a long time, It is possible to deodorize. This is preferable because it can efficiently remove harmful substances, but is not limited thereto. The air cap sheet absorbs heat and moisture. The air cap sheet adsorbs a vacuum air layer only by adhering the air cap sheet. The air cap sheet cuts off gaps through which air or air is introduced. As a result, The effect of increasing the temperature by about 4 ° C can be seen.

By including the embossing layer composed of the air cap sheet, the temperature of the indoor space can be maintained by the temperature increase effect of the internal space, and the heat loss is small, which results in the insulation effect of the indoor space such as the house, company and automobile. Further, by forming the adsorption layer on the convex surface of the air cap sheet, more harmful substances including the adsorption layer having a larger surface area can be adsorbed.

The thermoplastic resin may be selected from the group consisting of polyolefin, polyamide, poly lactic acid and polycaprolactone, but is not limited thereto. Preferably, it is a polyolefin, a general-purpose polymer and a low-cost polyethylene, but is not limited thereto.

The polyethylene is a polymer of ethylene and a thermoplastic resin having a specific gravity of less than 1 and a good flexibility at a low temperature. The polyethylene may be a high density polyethylene (HDPE), a linear low density polyethylene (LLDPE), a low density polyethylene Low Density Polyethylene (LDPE), and among the thermoplastic plastics produced by the polymerization of ethylene, linear low density polyethylene having good tensile strength, tensile elongation and rigidity is preferably used, but the present invention is not limited thereto. The linear low-density polyethylene usually has a small non-uniformity in molecular size as compared with low-density polyethylene. The molecular weight distribution of the linear low density polyethylene is similar to that of the high density polyethylene, and the melt viscosity is relatively high when heated. Since the crystallinity is usually better than that of low-density polyethylene, it has good rigidity and resistance to cracking, and tear resistance and surface hardness are comparatively large. At this time, since the linear low density polyethylene has a poor molecular formability when it has a large molecular weight, it is preferable to use a low molecular weight polyethylene having a relatively low molecular weight and it is necessary to increase the capacity of the extruder because of its high melt extrusion viscosity.

The pressure-sensitive adhesive may be selected from the group consisting of vinyl acetate, acrylic, ethylene vinyl acetate, cyanoacrylate, polyurethane, and polyvinyl alcohol, but is not limited thereto. The pressure sensitive adhesive layer coated with the pressure sensitive adhesive is formed. As a result, the pressure sensitive adhesive layer can be easily applied to the back surface without applying the adhesive on the back surface or applying the adhesive, so that the workforce and the working time can be minimized. The release layer is provided on the adhesive layer to protect the adhesive layer before application. After that, the release paper is separated and removed at the time of construction, and then the adhesive layer exposed to the outside is fixed by adhering to the wall surface, the car ceiling, the ceiling of the room, and the like. Therefore, the construction can be performed very easily.

The releasing paper is preferably made of polyester or polyethylene, and silicone can be further applied to the surface of the releasing paper so as to be easily removed from the pressure-sensitive adhesive layer during construction, but the present invention is not limited thereto.

The present invention relates to a sheet for functional embossing interiors and a method of manufacturing the same, including the following steps.

One aspect of the present invention is a method for forming an adhesive layer, comprising: (a) applying an adhesive to one surface of an embossed layer to form an adhesive layer;

(b) drying the embossed layer on which the adhesive layer is formed;

(c) forming an adsorption layer on the embossing layer on which the adhesive layer is formed; And

(d) forming an adhesive layer on the other side of the embossed layer;

. ≪ / RTI >

The present invention may further comprise the step of forming a surface layer selected from the group consisting of paper, leather, film, nonwoven fabric and cotton fabric on one side of the functional embossing interior sheet.

A surface layer selected from paper, leather, film, nonwoven fabric and cotton fabric may be formed on one side of the embossed interior sheet. The surface layer formed may be printed or molded with various designs of pictures or phrases to produce various indoor ambience. The basis weight of the paper, nonwoven fabric, cotton fabric, film or the like constituting the surface layer is preferably 80 to 200 g / m 2. When a surface layer within the above range is formed, damages such as tearing, crack opening and curling phenomenon can be prevented during the construction or use. In the case of the paper, it is made of pulp. In the case of the nonwoven fabric, the pulp and the polyester may be combined, but the present invention is not limited thereto.

In the step (a) of the present invention, the adhesive may be applied to one surface of the embossed layer at a thickness of 0.05 to 0.4 mm.

The thickness of the adhesive layer applied to the embossed layer is preferably 0.05 to 0.4 mm, but is not limited thereto. When the adhesive layer is applied in the thickness within the above range, the adhesive force is properly exhibited, and the contact area with the air can be increased without being buried in the adhesive layer when the powder of the adsorption layer is dispersed.

In the step (b) of the present invention, drying can be carried out at 50 to 90 ° C for 30 seconds to 3 minutes under drying conditions.

In the step (b) of the present invention, strong volatility can be expected by partially evaporating the solvent by hot-air drying the embossing layer coated with the adhesive solution for a short period of time. In this way, it is necessary to strengthen the adhesive force by partially volatilizing the solvent by hot air drying. The hot air drying for volatilizing the solvent of the adhesive solution applied to the embossing layer is preferably performed at 50 to 90 ° C for 30 seconds to 3 minutes, but is not limited thereto. When the drying conditions within the above range are satisfied, it is possible to prevent the decomposition of the adhesive layer and shorten the drying time, which is economical from the viewpoint of process productivity. It is also appropriate that the wind speed of the hot air at the time of drying is 1 m / sec or less.

In the step (c) of the present invention, the average particle diameter of the powder of the adsorption layer is preferably 0.01 to 1.2 mm, but is not limited thereto. When the powder has an average particle diameter within the above range, the powder can have a large surface area, thereby improving deodorization and adsorption performance.

In the step (d) of the present invention, the pressure-sensitive adhesive layer may be a layer coated with a pressure-sensitive adhesive, and the pressure-sensitive adhesive may be a layer of a vinyl acetate type, But is not limited thereto. The pressure sensitive adhesive layer coated with the pressure sensitive adhesive is formed. As a result, the pressure sensitive adhesive layer can be easily applied to the back surface without applying the adhesive on the back surface or applying the adhesive, so that the workforce and the working time can be minimized.

Further, the functional embossing interior seat of the present invention is manufactured in the form of a sheet, and can be spread over the whole inner space, so that the effect of heat insulation, soundproofing, and shock absorption in the interior of the interior can be seen. In addition, it is easy to remove in the form of a sheet, and by including the adsorption layer, it is possible to deodorize and adsorb harmful substances, odors, dust and the like in the inside of the room, thereby contributing to a pleasant environment and energy saving.

In addition, the functional embossing interior sheet of the present invention has a bulky surface area of the embossed layer, and the contact area of harmful substances, odors, dust, etc. inside the interior is widened, so that the residence time in the functional embossed interior sheet is prolonged, have.

In addition, the functional embossing interior sheet of the present invention may have its own flexibility or may be folded and stored and transported with a small volume.

How to measure property

1) Deodorizing performance

The deodorizing performance of the prepared functional embossing interior sheet was compared with that of TVOC (toluene) and formaldehyde mixed gas. The deodorizing performance test was carried out by using a deodorizing panel having a size of 66 ㎖ in a 30 ℓ chamber. After a certain amount of mixed gas was injected and the initial concentration was measured, the internal concentration was changed by gas chromatography Gaschromatography and indoor air quality analyzer. At this time, the temperature was maintained at 25 DEG C and the relative humidity was maintained in the range of 50 to 60%.

2) Thermal conductivity

The thermal conductivity values of the functional embossing interior sheets prepared in the above Examples and Comparative Examples were measured at 600 DEG C using a thermal conductivity measuring apparatus (NETZSCH, LFA 457).

[Example 1]

An adhesive solution (concentration 20% by weight) in which polyvinyl alcohol (hydrolyzed 99%, weight average molecular weight 100,000 g / mol) and water were mixed was prepared and the adhesive solution was sprayed and dispersed on one surface of the embossing layer to uniformly Lt; / RTI > The coated embossing layer was dried with hot air at 70 캜 for 1 minute. An ion exchange resin powder having an average particle diameter of 0.4 mm was prepared by using a strong acidic cation exchange resin (TRILITE CMP28, Samyang Corp.) using a pulverizer. The ion-exchange resin powder was spray-dispersed at 350 g / m < 2 > and applied to an embossing layer having an adhesive layer formed thereon to prepare a functional embossing interior sheet. An acrylic adhesive was applied to the other side of the embossed layer of the functional embossing interior sheet to form an adhesive layer. At this time, the adhesive layer was protected with a polyester release paper coated with a thin silicone. A sheet for wallpaper was prepared by attaching paper printed with a pattern pattern on the surface coated with the functionalized embossing interior sheet absorbent layer.

[Example 2]

Except that a strongly basic anion exchange resin (TRILITE AMP16, Samyang Corp.) was used as the adsorption layer in Example 1 above.

[Example 3]

Except that a weakly basic anion exchange resin (DIAION WA20, Samyang Corp.) was used as the adsorbent layer in Example 1 above.

[Example 4]

Except that a weakly acidic cation exchange resin (DIAION WK60L, Samyang Corp.) was used as the adsorption layer in Example 1 above.

[Example 5]

Except that 100 parts by weight of strongly acidic cation exchange resin (TRILITE CMP28, Samyang Corp.), 70 parts by weight of impregnated activated carbon, and 348 g / m 2 by 40 parts by weight of the soaking powder were used as the adsorption layer in Example 1.

[Example 6]

Except that 100 weight parts of a strong basic anion exchange resin (TRILITE AMP16, Samyang Corp.), 60 weight parts of zeolite and 20 weight parts of elvan stones were dispersed as an adsorbent layer at 340 g / m < 2 >

[Comparative Example 1]

In the same manner as in Example 1, except that a flat polyethylene film was used as the embossing layer.

[Comparative Example 2]

The embossing layer was formed in the same manner as in Example 1, except that the polyurethane foam was used instead of the air cap sheet.

The physical properties of Examples 1 to 6 and Comparative Examples 1 to 2 were measured and are shown in Table 1 below.

Deodorization performance (%) Thermal conductivity (W / mK) toluene Formaldehyde Example 1 96.5 85.5 0.021 Example 2 95.2 83.3 0.021 Example 3 94.6 84.5 0.023 Example 4 95.9 85.7 0.022 Example 5 97.0 86.1 0.020 Example 6 96.9 86.3 0.021 Comparative Example 1 80.8 70.9 0.036 Comparative Example 2 75.5 52.1 0.030

As shown in Table 1, when Examples 1 to 6 and Comparative Examples 1 and 2 are compared, it can be seen that the deodorizing performance is excellent in the examples. In the case of Comparative Example 1, since the surface area was smaller than that of the Example, the deodorizing performance was low. In the case of Comparative Example 2, the adhesive was not evenly dispersed due to the pores of the polyurethane foam, so that the adhesive coated with the powder of the adsorbent layer was buried in the powder, resulting in poor deodorization and adsorption performance. In addition, even in the case of the heat insulating performance, in Comparative Examples 1 and 2 which did not include the air cap sheet, the thermal conductivity was high and the heat insulating effect was remarkably low as compared with the examples. Further, even when the powder composition comprising a plurality of powder of the adsorbing layer was used as in Examples 5 to 6, the deodorizing performance and the thermal conductivity were not lowered, and further superior results were confirmed.

Accordingly, the present invention can be applied to remove harmful substances, odors, dust, and the like that cause allergic diseases in an indoor space such as a house, a company, and an automobile where toxic substances may occur due to excellent deodorization performance of harmful substances. In addition, by including the embossing layer, it is confirmed that it can be applied to the interior space that is comfortable and energy saving by increasing the temperature rise and energy efficiency of the indoor space by the excellent heat insulating effect in the indoor space.
