Description

[0001] The present invention relates to a profile for a direction window and a manufacturing method thereof,

The present invention relates to a directional window profile and a method for producing the same, and more particularly, to a wood-flavor composite comprising a powdery flavor added to raw materials before profile extrusion such that the aroma of the window profile is continuously radiated for a long period of time And a perfume is diffused by imparting a direction, and a manufacturing method thereof.

Generally, a window means a window and a door of a building, and has a function of a wall dividing the inside and the outside of a building or a house. The function of the window is airtightness, heat insulation, soundproofing, and the like.

Such a window is mainly composed of a profile formed by extrusion molding of a window frame using a synthetic resin such as PVC as a frame constituting the basic structure thereof. In the window profile, a decorative film (sheet paper) of a synthetic resin material is attached to the top surface or the side surface exposed to the outside at the time of construction so as to have a wood texture rather than a synthetic resin texture to enhance aesthetics. However, in order to attach a separate film or sheet to the extruded profile of the window, it is necessary to separately move to the place where the profile wrapping facility is installed, and then to process the wrapped profile by lapping the extruded profile separately. And it is difficult to repair when the lapping is carried out, machined or scratched during construction, and since it uses an adhesive for lapping, it is disadvantageous to the operator and the user.

In order to overcome this, a double extrusion (coextrusion) method was used to extrude a double profile of a window profile. The double extrusion is a method of extruding and attaching PVC or other raw materials to one side of a profile by using a secondary extruder in a state in which the profile is extruded to have a constant shape by using an extruder as described above. In this case, however, the appearance of the profile surface to which the PVC and the like are applied is disadvantageous in that the appearance of the surface of the profile is not natural, and the profile surface of the PVC pigment has a problem of discoloring and detracting from the appearance.

On the other hand, in the case of the window profile, there is a disadvantage in that the direction is not given and the plastic odor is just as it is, and the fragrance is not good. Even if the fragrance is included, And thus it has been disadvantageous to add too much perfume to the molding, which may adversely affect the molding of the synthetic wood.

Recently, we are pursuing the use of eco-friendly products as building and housing interior and exterior materials. We are also pursuing the use of eco-friendly products as building materials, housing materials, and other hazardous substances, resulting in instability in mind and body, And the living health is becoming very poor.

For this reason, in response to the desire to protect family members, modern people who use music therapy, painting therapy, fragrance therapy using fragrance or fragrance are increasingly used as a kind of psychosomatic therapy.

In particular, the use of oriental products such as perfumes and spices is so old as to be comparable to the history of mankind. In general, it is said that a fragrance is a solid or powdery one in the directional substance (fragrance substance) .

The use range of perfume and fragrance is very wide, but the fragrance and the fragrance as a cosmetics are incense to the body and the costume to obtain the effect of spiritual beautification together with a feeling of cleanliness.

Aromatherapy using the herbal vegetable aroma is to obtain positive effects on the body and mind by using essential oils obtained from flowers, leaves, stems, roots, and fruits of plants.

It has been in the twentieth century that such aromatherapy has been studied scientifically and has received attention as an area of alternative medicine.

For the above reasons, there have been many researches on various directional products such as wallpaper, flooring, decorative materials, and windows as materials for building materials, especially indoor space which is a living space.

According to this trend, Korean Patent Laid-Open Publication No. 2000-0061974 discloses a functional wallpaper containing medicinal plants used in aroma therapy, and Korean Patent Publication No. 2000-0053993 discloses a wallpaper Of wood flour and herb plants.

However, the conventional wallpaper has a problem that the fragrance is excessively diverged by heat, the directional direction capsule is destroyed during the manufacturing process, the persistence of the fragrance is reduced, and the efficiency of the fragrance is very low.

In addition, as the role of the window just as a component of a simple building has been improved in living standard and residential environment, various functionalities and ornaments have been required, so that even a general window has been coated with a perfume mixed with a functional oil. However, There is a problem that the provision of a direction as a coated level is only temporary.

Therefore, there is a need to develop more sophisticated windows that can be used for a long period of time while maintaining the direction effect for a long period of time.

3 is a view showing a configuration of a secondary extruder for producing a skin layer of a direction window profile according to the present invention.

1 and 2, a directional window profile 100 of the present invention is formed with a profile 10 having a predetermined cross-sectional shape, and has a predetermined thickness The skin layer 12 is formed.

The profile 10 and the skin layer 12 formed on the upper surface thereof are preferably co-extruded using the molding apparatus shown in FIG. When the coextrusion method is used, it is possible to implement various colors in the window profile, and by integrating the skin layer with the profile, the post process such as attaching the sheet after the profile production is unnecessary, thereby reducing the cost and improving the workability of the product Moreover, since no adhesive is used, it is eco-friendly and has an advantageous effect on surface scratching.

The thickness of the skin layer 12 may be in the range of 0.3-0.6 mm, preferably 0.5 mm.

The resin composition for co-extrusion of the present invention includes a synthetic resin, wood powder and fragrance complex.

That is, the wood powder-eye complex is mixed with the raw material of the composition for coextrusion to form the skin layer 12 formed on the upper side of the profile 10 of FIG. 1, and coextruded to form a skin layer So that the window profile has the texture of natural wood while having the directionality.

The wood-flavor composite contained in the resin composition for co-extrusion is contained in the range of 15 to 30 wt% based on the total weight of the resin composition and 70 to 85 wt% of the synthetic resin, .

The synthetic resin can be used without limitation as long as it is a thermoplastic resin used for forming a profile for a window. More preferably, the synthetic resin is selected from the group consisting of polystyrene (PS), polyethylene (PE), polypropylene (PP), polyvinyl chloride It is preferable to use at least one selected from acrylate-acrylate-acrylate-acrylate-acrylonitrile (ASA) copolymer resin and acrylonitrile-butadiene-styrene (ABS) copolymer resin.

The wood-flavor complex may comprise 60 to 99% by weight of wood flour and 1 to 40% by weight, preferably 70 to 90% by weight of wood flour and 10 to 30% by weight of fragrance, 85% by weight and the fragrance within the range of 15 to 20% by weight is preferable to the profile for the window because it gives a good direction along with the feeling of wood.

The wood-flavor complex may be one obtained by adsorbing a liquid flavor to the wood powder. In this case, the adsorption may be performed by absorbing the liquid flavor to the wood powder, and the wood powder-flavored complex to which the liquid flavor is adsorbed is preferably water-soluble resin such as polyvinyl alcohol or the like, It is possible to further slow the volatilization rate of the liquid flavor adsorbed in the wood flour and to allow the flavor to be slowly released, that is, slowly.

Alternatively, the wood-flavor complex may be one in which the wood and the fragrance of a solid phase are combined with a binding agent. In this case, most of the powdered form of the wood and the solid fragrance can be combined with one another on a solid and bound using a binder to fix these solid materials to one another. The binder may be at least one selected from the group consisting of carboxymethylcellulose (CMC), starch, gum arabic, gelatin and polyvinyl alcohol (PVA), but these are merely illustrative, , It being understood by those skilled in the art that other binders, preferably water-soluble and / or water-degradable polymeric materials, are usable and that the present invention is intended to include these.

Preferably, the binder is contained in an amount within a range of 1 to 30 parts by weight based on 100 parts by weight of the wood-flavor complex, so that the wood and the fragrance of the solid phase can be adequately bonded with sufficient strength. Thus, it will be appreciated that most solid orienting products can be applied as they are, and those skilled in the art will be able to purchase and use solid orienting products commercially. As described above, the wood-flavor complex in the form combined with the binder can be pulverized through a pulverizing process to have an appropriate particle size, for example, an average particle size of 1 to 100 mu m, and within this range, Sponge composite can easily mix and knead with the synthetic resin constituting the skin layer of the window profile to facilitate the production of the skin layer of excellent physical properties. However, the degree of the above pulverization, that is, the range of the average particle size, And the present invention is not intended to be limited thereto.

Preferably, the solid perfume comprises a perfume material; And a polymer layer coated with urea-formaldehyde or melamine-formaldehyde on the outer periphery of the perfume material. However, the directional capsules are illustrative, and the present invention is not intended to be limited thereto. The directional capsules have an average particle size within a range of 1 to 100 탆, which facilitates the mixing and kneading of the synthetic resin with the synthetic resin constituting the synthetic wood, thereby facilitating the production of synthetic wood with excellent physical properties. The range of average particle sizes of the directional capsules is exemplary and is not intended to be limiting.

The fragrant materials constituting the wood-flavor composite or fragrant materials which can be used in the production of the directional capsules can cause good feelings by stimulating the olfactory sense of humans, and they can be used as terpenes known as flower fragrance, fruit flavor, And wood aromas. For example, natural or complex flavors such as lavender, pine, incense, rose, rosemary, peppermint, jasmine, apple, orange, acacia, banana Incense, and chocolate flavor.

The polymer material constituting the polymer layer that can be used in the production of the directional capsules must have a release characteristic that the fragrance ingredient is not volatilized as much as possible by encapsulating the fragrance material with a resin so as to surround the fragrance material. And the polymer layer is destroyed so that the fragrance material is volatilized. The resin used for the polymer layer is preferably urea-formaldehyde, or melamine-formaldehyde. The directional capsules can be produced by completely wrapping the polymeric material for a polymer layer around a solid or liquid perfume material as much as possible by a known method of spray drying, interfacial polymerization, phase separation, or polymerization. The directional capsules are preferably in the form of ordinary powders, and preferably have an average particle size of 1 to 100 mu m. When the particle size of the particles is less than 1 mu m, the degree of dispersion during work may be reduced or aggregation may occur, If it exceeds 100 탆, it may be undesirable since it may cause precipitation or uniform coating in the work.

The resin composition for co-extrusion may further contain an antibacterial agent to prevent discoloration or corrosion. The antibacterial agent may be an inorganic antibacterial agent, an organic antibacterial agent, or a natural antibacterial agent extracted from plants. The inorganic antibacterial agent may be a zeolite type aluminosilicate and zinc oxide or a silver zirconium type silver silver zirconium phosphate. The organic antimicrobial agent may be an antimicrobial agent produced through organic synthesis such as chlorine, bromine or imidazole. The natural antimicrobial agent may be an extract plant extract from grapefruit, gosam, cotton wool, magnolia, cinnamon and the like.

It is preferable to use a natural plant extract as the antimicrobial agent.
