Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective sheet for wood furniture,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a protective sheet attached to wood furniture having far-infrared radiation and antibacterial properties, and more particularly, To a protective sheet attached to wooden furniture so as to have far-infrared radiation and antimicrobial properties so that far-infrared rays are emitted from the furniture, and the effect of antibacterial and deodorization can be seen.

Generally, wood is widely used for construction, furniture, packing boxes, ships, vehicles, gangs, sleepers, electric poles, musical instruments, exercise balls, plywood, pulp, charcoal, fuel, It is also used as a raw material for chemicals.

In addition, since the wood can be transformed into various forms as well as having various forms, it has become a most useful and useful building material. In addition, even today, when metal and plastic structural materials have been developed, wood is the only material that can be easily fabricated with a complete structural frame.

In addition, since most of the furniture used in the home has been wood for a long time to this day, the material of the furniture has been made of light wood such as the traditional zucchini, beech, birch and cherry tree. However, Nawang, Teak and Walnut are imported and used. Korean traditional furniture materials such as fir, paulownia, zelkova, maple, ginkgo, hodoki, and pine were used, and special items such as rosewood, ebony, etc. were used. The greatest advantage of wood is that it has a unique pattern of wood, but it has the disadvantage of being easy to twist.

Since the main component of wood is hygroscopic as cellulose, water is added to the wood due to increase or decrease of humidity in the atmosphere, and the cells expand and contract with the moisture, and the shrinkage amount in the longitudinal direction and the lateral direction is about 20 times different, The horizontal and vertical joints are twisted or cracked, so you can use a dry material that has a moisture content of 8 ~ 12% beforehand, or you can use a plywood that is made by cutting the wood thinly and crossing the direction of the grain at 90 °.

In addition, by using a rigid hard board that is disassembled into a particleboard or fiber state made by hardening the wood into a chip state, the anisotropy of the wood is prevented and warping is prevented, and the wood is made into a thin slab material, A lumber core may be used, or a hollow structure may be employed in which a thick plank is entwined or a honeycomb core is inserted so that it is light and does not twist.

However, since the wood has a low hardness, the surface of the wood is susceptible to damage, and various synthetic resin sheets are surface-processed, and the wood is thermally adhered or pressed to the wood.

In this case, recently, it has been revealed that far-infrared rays are radiated from the wood to produce a useful effect on the human body, but the preference of the wood is increased, but there is a problem that the far-infrared ray emissivity is lowered by the surface treatment.

In addition, applications derived from the petrochemical industry include toxic substances that release volatile organic compounds (VOCs) that harm human health and hygiene.

The VOC is a substance to be regulated in accordance with the Environmental Notification No. 1998-77, which is a harmful substance to the human body and emits odor. For example, methanol for artificial wood production releases formaldehyde, a toxic chemical, which is a colorless transparent representative carcinogen used for preservation, disinfection and sterilization. That is, if the human body is exposed to formaldehyde at a concentration of 30 ppm in the air for 1 minute, symptoms such as memory loss or difficulty in concentrating may occur.

In the residential environment, wallpaper, flooring, flooring, various plywood, etc. release various toxic VOCs. These toxic substances, such as VOCs, are the main cause of sick house syndrome, a new disease that causes respiratory disease, headache, vomiting, dizziness, itching, atopic disease, insomnia or discomfort. In the case of wallpaper or plywood using formaldehyde, the release is most severe up to 6 months after the expansion, and it is released even from 5 to 10 years.

In order to prevent such sick house syndrome, institutional support such as 'Act on Promotion of Purchase of Eco-friendly Products' and 'Law on Air Quality Control of Multi-use Facilities' are being provided. The use of materials that release a large amount of pollutants has been banned, and it has become imperative that eco-friendly products be used at national and public multi-use facilities over 1,000 square meters. At the private enterprise level, eco-friendly products, for example, cyanide, photocatalyst coded, charcoal and loess are added and developed.

According to the present invention, by applying a functional healing ceramic coating material applied to a protective sheet so as to have far-infrared radiation and antimicrobial properties in wood furniture, far-infrared rays are emitted from wood furniture, and the effect of antibacterial and deodorization can be seen.

In addition, there is an effect that, for example, a student or a worker who mainly uses a desk, neutralizes the far-infrared ray emitted from a paint, or the electromagnetic wave emitted from a computer, a monitor, or a cellular phone, thereby minimizing the damage caused by electromagnetic waves.

Hereinafter, preferred embodiments of the present invention will be described.

The composition of the functional healing ceramic coating applied to the protective sheet to have far-infrared radiation and antimicrobial activity in the wood furniture of the present invention comprises 35 to 65% by weight of silicon dioxide, 10 to 15% by weight of loess, 10 to 10% By weight of calcium oxide, 0.1 to 1% by weight of magnesium oxide, 3 to 6% by weight of potassium oxide, 0.1 to 5% by weight of calcium oxide, 2 to 6% by weight of sodium oxide, 0.1 to 1% by weight of titanium dioxide, and 1 to 3% by weight of UV-curable adhesive.

The silicon dioxide is an oxide of silicon and is generally referred to as silica, which refers to silicic acid as a component of various silicates existing in nature. The chemical formula is SiO ₂ and is naturally produced as crystals or amorphous crystals in quartz, quartz, agate, agate, flint, silica, iridium, and lycra.

In addition, silicon dioxide is a mineral in which many kinds of variants exist, and the color tone is variously expressed as colorless, white, gray, yellow, brown, black, purple, red, green and blue and is transparent or translucent.

The alumina is a chemical formula Al ₂ O ₃ as an oxide of aluminum, has the property, such as diamond, and then had a thin hardness, and heat resistance required for the ceramic, chemical resistance, and strength.

The ferric iron oxide is an iron oxide, and the formula is Fe ₂ O ₃ , and has excellent coloring power and is stable to sunlight, air, moisture, heat, acid, and alkali.

The calcium oxide is calcined with an oxide of calcium, and its chemical formula is CaO, and is used as a colorant-retaining agent and a drying agent.

The magnesium oxide is magnesium oxide, MgO is used as a catalyst, an adsorbent, and a sintered body.

The potassium oxide is an oxide of potassium, the chemical formula of which is K ₃ O and is hygroscopic.

The sodium oxide is an oxide of sodium, the formula is Na ₂ O, and is used as a disinfectant.

The titanium dioxide has a chemical formula of TiO ₂ , has a large oxidizing power, has a high antibacterial action, and has properties of odor removal and sterilizing action.

The loess can be collected from a habitat or the like. It is preferable that the particle diameter is about 0.002 to 0.005 mm. For example, if it is less than 0.002 mm, the far-infrared ray emission effect is lost, and if it exceeds 0.005 mm, powder coating is difficult.

The loess is preferably baked at 800 to 900 DEG C for 1 to 3 hours. This is to ensure the characteristics of the flame retardancy by removing the water and the substances which can be burned out contained in the loess.

On the other hand, the far infrared ray emitted from the loess has the most beneficial wavelength (5.7 ~ 10 ㎛) in the human body, penetrates into the deep layer of the skin (3 ~ 4 cm deep), accelerates the cell to increase the body temperature, It has a remarkable effect on the promotion of growth. Especially, due to the excellent effect obtained when a large amount of sweat is released, various kinds of toxic substances, waste materials and heavy metals are released together with sweat, and the constitution is improved to a healthy alkaline. It also relaxes the physical and mental tensions, so stress relief, which causes adult diseases, also works.

The above-mentioned wooden piece is used for finely manipulating wood made by finely crushing oak. In addition, the above-mentioned wood fragments soften the viscosity of the loess before curing, thereby making it possible to render the loess into remicon, retaining the inherent properties of the hardened loess, enhancing heat conductivity and heat retention, . Further, after the yellow clay is cured, the surface is prevented from cracking.

Of course, the wooden piece is not limited to oak, and any wood can be used. For example, pine, oak, and the like can be used. In some cases, it may be possible to improve the recyclability of resources by using sawdust or shredder obtained by surplus after being used as building material.

The UV curing type adhesive is cured when exposed to ultraviolet rays to exhibit a strong adhesive force, and is preferably made of an acrylic monomer or an oligomer.

For example, a UV polymerizable oligomer, a reactive diluent, an additive, and a photopolymerization initiator. The oligomer is a modified acrylic oligomer, such as epoxy, polyester, urethane, and the like. The reactive diluent is used as an acrylic monomer and acts as a solvent for additives and initiators and affects physical properties after the reaction. The additive is composed of an adhesion-imparting agent, a filler, a polymerization inhibitor, a thermosetting catalyst, an anaerobic catalyst, a coloring agent and the like.

A method for producing a sheet by the composition of the paint applied to the wooden furniture protection sheet thus prepared will be described below.

First, the composition of the paint described above is applied to a fabric sheet for furniture protection of wood.

In this case, the wooden furniture protection sheet is preferably a sheet made of polyvinyl chloride resin (PVC) as a main material. Of course, the present invention is not limited thereto, and any sheet used for protecting wooden furniture can be used.

For example, the wood furniture protection sheet may comprise 90 to 96 weight percent polyvinyl chloride resin, 1.5 to 5.5 weight percent plasticizer, 1.5 to 5.5 weight percent stabilizer, 0.5 to 4.5 weight percent lubricant, 4.5% by weight of a filler, i.e., an additive.

That is, the paint is applied to the surface of the wooden furniture protection sheet prepared as described above to a predetermined thickness using a spray gun or a brush. At this time, the coating thickness is preferably 1: 0.05 to 0.1 in comparison with the thickness of the sheet. For example, if it is less than 0.05, the effect of coating the sheet is lost. If it is more than 0.1, it may interfere with adhesion of the sheet to wooden furniture and the smooth adhesion state can not be maintained.

Then, when the coating of the paint on the wooden furniture protection sheet is completed, the UV curable adhesive contained in the composition of the paint is cured by passing the coating through a UV irradiator so that the paints applied to the wooden furniture protective sheet can be firmly adhered .
