The present invention relates to a hotfix, which is a kind of ornaments, and more particularly, to a hotfix and a method of manufacturing the same, which are easy to manufacture and have a beautiful appearance and excellent adhesion to clothes.

In general, a hot fix is an ornament that is attached to clothes, bags, shoes, and hats to give a three-dimensional decorative appearance to a product. The shape of a hemisphere having an arc or polyhedron structure made of metal, glass, aluminum, etc. Is done.

Such a hotfix is applied to a textile material that requires decoration by applying an adhesive made of a material such as silicone to the bottom thereof.

However, since the conventional hotfix is made of a material such as metal, glass, a lot of manufacturing cost is required, and a large amount has a significant weight as a whole when attached, there is a problem that may be uncomfortable by the load when using the attachment.

In addition, the conventional hotfix has a problem that does not give a sufficient decorative effect for a long time because when used to coat a high-gloss material to improve the appearance is used for a long time or easily peeled off by an external contact.

In addition, the conventional hotfix requires physical properties such as water resistance, detergent resistance, solvent resistance, etc., because it is attached to the fiber, etc., but does not correspond to this, in particular, because the adhesive strength is weak, easy to fall off, there is also a problem that inhibits the appearance of the skin complex.

The present invention has been devised to solve the above problems, by using a single mold to produce a plurality of stones at the same time, such as acrylic resin, hotfix production by allowing the UV coating and deposition process, and adhesive coating process to proceed The goal is to provide a hotfix that is simple and can significantly reduce manufacturing costs.

In addition, the present invention is a hot fix that can solve problems such as peeling off the coating surface even after long time use by strengthening the adhesion of the coating film and metal thin film coated on the stone by the UV coating process using a soft coating agent in the UV coating process There is another purpose to provide.

In addition, the present invention has another object to provide a hot fix that can be firmly attached to the decorative object by using an adhesive containing a phenol component and a liquid paraffin oil component to maintain a stable attachment even when washing or external impact.

Hotfix according to the present invention for realizing the above object is a stone that is injection-molded with a plastic resin so that the decorative surface has a polygonal shape and the bottom surface is formed in a plane, and the epoxy resin and copper rust oil component on the decorative surface of the stone A soft coating film formed by UV coating with the soft coating agent; A metal thin film formed by vacuum deposition on the bottom surface of the stone; And an adhesive layer applied on the metal thin film at the bottom of the stone.

Hereinafter, a preferred embodiment of the present invention with reference to the accompanying drawings as follows.

The method of manufacturing the hotfix of the present invention will be described with reference to FIGS. 1 and 2 as follows.

1 and 2 is a view showing a hotfix manufacturing process according to the present invention in order.

First, as shown in FIG. 1A, a plurality of stones are simultaneously injection molded using the stone forming mold 10.

The stone forming mold 10 has a plurality of stone forming portions 11 are formed to produce a plurality of stones together, and the stone forming portions 11 may be injected with a plastic resin solution, which is a material of the stone. Configured to be interconnected to the gate 13.

As described above, the injection molding manufactured through the mold 10 has a structure in which a plurality of stones 22 are interconnected by the gate part 24 formed by the gate 13 as shown in FIGS. 3 and 4 (hereinafter, ' Stone connection body 20 ').

Particularly, in the injection process of the present invention, without using a release agent such as silicon, the injection material, that is, the stone connector 20 is manufactured to be separated from the mold 10, which is a release agent such as silicon on the surface of the stone 22 This is because the deposition surface may deviate from the stone 22 in the deposition process after the UV coating process.

The material of the stone 22 is acrylic resin, including vinyl chloride (PVC: polyvinylchloride), polyethylene (PE: poly ethylene), polycarbonate (PC: polycarbonate), polystyrene (PS: poly styrene), etc. Plastic resins such as resin and AS resin (acrylonitrile styrene copolymer) and ABS resin (acrylonitrile butadiene styrene copolymer) are used.

The acrylic resin is a polymer from esters such as acrylic acid and methacrylic acid. The acrylic resin is colorless and transparent, and has a characteristic of transmitting light, especially ultraviolet rays, better than ordinary glass, does not discolor when exposed to the outdoors, and has good chemical resistance and electrical insulation. And water resistance and the like all have good characteristics.

In addition, the resins such as PVC, PE, PC, PS, AS, ABS and the like also have excellent heat resistance, and can be used as a material for hotfixes because they have transparency, solidity, and impact resistance.

Therefore, the present invention does not use a glass material or a metal material such as aluminum, but uses a pure plastic resin as a material to mix the pigment according to the color, and then injection by using the mold for forming the stone (10) When forming, it is possible to produce stones having various basic colors.

Next, as shown in (b), (C), (d) of Figure 1 is subjected to UV coating on the stone connector 20 produced through the mold 10 as described above.

The UV coating (Ultra Violet coating) is a process of forming a coating film 25 to form a protective film on the surface of the stone connecting body 20, that is, the decorative surface of the stone 22 to realize a stable color, After spraying a soft UV resin (soft coating agent) on the stone connector 20 as shown in 1 (b), and then provides a strong wind to the stone connector 20 as shown in Figure 1 (C) to the surface of the stone The thickness of the coating film 25 to be coated to approximately 10 to 20㎛ uniformly. Thereafter, as shown in (d) of FIG. 1, the ultraviolet light generated from the UV lamp 40 is used to cure the coating film 25.

In the UV coating process, UV resin, that is, UV curing paint is used. The paint is composed of urethane acrylate, monoma, diluent of photoinitiator, and other preparations. It may work.

Here, since the conventional UV resin is hardened at high speed, the soft UV resin is used as described above for producing a hotfix according to the present invention, which is formed on the bottom surface of the stone 22 in a deposition process to be performed later. The purpose of the present invention is to add adhesion to the thin film and to increase deposition efficiency. That is, when the UV coating, since the soft UV resin is coated on the decorative surface of the stone 22 as well as partly coated on the bottom surface of the stone 22, when the coating of the metal thin film is made after the coating, the soft UV resin is The action of strengthening the adhesive force can increase the deposition efficiency.

Such a soft UV resin is used by mixing a solvent such as epoxy resin and copper rust oil (methyl salicylic acid) with a commonly used UV resin as described above to have soft properties. At this time, the mixing ratio of the epoxy resin and copper rust oil is preferably used by mixing about 20% by weight and 0.1% by weight relative to the total resin weight.

In the epoxy resin serves to enhance the adhesion of the coating film 25 and the metal thin film 27 to be proceeded later, the copper rust oil serves to delay the drying to some extent while softening the UV resin.

On the other hand, it is preferable that the above-described soft UV resin spraying process, the coating film homogenization process by strong wind, and the coating film curing process using the UV lamp are made while rotating the stone connecting body 20.

That is, as shown in FIG. 5, the stone connecting body 20 is fixed to the rotating shaft 32 protruding from the rotating table 30, and the rotating shaft 32 and the stone are driven using a driving means such as a motor 34. It is preferable that the soft UV resin spraying step, the strong wind providing step, and the coating surface curing step are performed while rotating the connector 20.

UV coating process as described above, by using the ultraviolet energy to instantaneously irradiate high energy without deformation of the material to form a ductile coating film 25 on the surface of the stone 22, chemical resistance, heat resistance, It gives effects such as wear resistance, high hardness, and high gloss.

Next, as shown in FIG. 2E, when the UV coating process is completed as described above, the deposition process of the metal thin film 27 is performed on the stone connector 20.

That is, the UV-coated stone connector 20 may be placed in the deposition chamber 42, and a metal (such as non-metallic material may be used) may be deposited on the surface of the stone connector 20 in a high vacuum state. An electric current flows through the heating coil 43 in which the piece 44 of the object to be deposited, such as metal (Al) or chromium (Cr), is fixed, and is heated in a high vacuum state so as to form a thin film (27) such as aluminum on the bottom of the stone (22). ) Is deposited.

At this time, the temperature and temperature are adjusted so that aluminum molecules and the like may be finely applied to the surface of the UV coating film 25 of the stone connector 20 in a vacuum state, and the deposition process is performed at about 10 to 20 minutes at room temperature. It is preferable.

When the aluminum thin film is deposited on the bottom surface of the stone 22 as described above, the adhesion strength of the metal thin film may be improved by the adhesive force of the epoxy resin included in the soft coating agent of the UV coating process, and the stone may be formed of a plastic material. Even if it is formed, the light is disturbed as light passes through the stone due to the light reflecting effect of the thin film, so that the entire hotfix can generate beautiful light like a gem.

Next, as shown in (f) of FIG. 2, a vinyl adhesion process is performed for the adhesive application process to be performed.

The vinyl bonding process is performed to prevent the adhesive from being applied to the decorative surface of the stone 22 to be a finished product, and the protective vinyl 50 is placed on the opposite side (upper surface in the drawing) to which the adhesive is applied, When the protective vinyl 50 is squeezed to the stone connecting body 20 by using a pressing means 55 having elasticity such as a sponge, the decorative surface of the stone 22 in which the protective vinyl 50 is formed in a hemispherical shape or the like, that is, It adheres in a stable state on the UV coating film.

In this case, since the protective vinyl 50 must be continuously attached to the surface of the stone 22, when the stone 22 is commercialized, the protective vinyl 50 is not hardened to have an adhesive force without affecting the surface of the stone 22. It is preferable to use the adhesive which isolate | separates.

In addition, the protective vinyl 50 may include a plurality of holes 52 in an empty space without a constituent portion of the stone connector 20 as shown in FIG. The excess adhesive is discharged into the hole 52 by forming a) so that the adhesive flows between the stone 22 and the vinyl 50 to prevent the problem of contaminating the decorative surface of the stone.

Next, an adhesive coating process is performed on the rear surface of the stone connecting body 20 as shown in FIG.

In the adhesive application process, the adhesive 29 having a component to be described in detail below is sprayed onto the bottom surface of the stone 22 on which the aluminum thin film is formed in the stone connecting body 20.

The adhesive 29 used here is not a commonly used adhesive, but is specially manufactured so that the stone 22 is completed and a commercialized hotfix can be attached to a material such as fiber in a stable state.

That is, the adhesive 29 is configured to have a water resistance, detergent resistance, solvent resistance, etc. so that the hotfix of the present invention has a sufficient adhesion to the fiber material, such as clothing, and also have sufficient adhesion performance to washing and the like.

 Referring to the physical properties and manufacturing process of the adhesive applied to the stone as follows.

The adhesive applied to the hotfix of the present invention is basically manufactured so that fibers such as streams can be attached in a strong and stable state.

Usually, the adhesive applied to the stone is mainly composed of EVA and urethane resin, and a small amount of additives and a solvent are mixed and used. However, the adhesive of the present invention consists of an appropriate amount of phenol resin and a liquid paramin oil mixed with the constituents. .

Referring to one embodiment of the manufacturing method of such an adhesive, first mixing 15-25% by weight of urethane resin, 35-45% by weight phenol resin, 35-45% by weight EVA, 0.1-1.0% by weight of liquid paraffin oil, Melting is carried out with a water bath using the breaking water, that is, steam.

Preferably, 20% by weight of urethane resin (ESTANE), 40% by weight of phenol resin, and 40% by weight of EVA are mixed, and the liquid paraffin oil is mixed with 0.5% by weight of phenol or EVA component.

The reason why a small amount of the liquid paraffin oil is added in the above is that the phenolic resin is cured as soon as it is dissolved in heat, thereby acting to delay the curing of the phenolic resin to enhance adhesion to textile products such as clothing.

The urethane resin generally refers to a thermoplastic polyurethane administered to an adhesive.

The phenol resin is a rosin-based tackifier to increase the surface tackiness, it is possible to use a phenol-formaldehyde-based resin, it is preferable to use ESCOREZ 1203 (RESIN, Japan TONEM Chemical).

These phenolic resins are well melted even at low temperatures, making it easy to manufacture adhesives, and have been found to exhibit excellent adhesion even in hot water, particularly through aberration tests. Therefore, the adhesive should be sufficiently adhered even at high temperatures, such as when washing, such as when the hotfix is attached to the fiber, but the adhesive in the present invention has superior adhesive strength by containing phenolic resin than the conventional adhesive using EVA as a main component. It is possible to provide a stable and firm attachment state.

The EVA (Ethylene-Vinyl Acetate) is generally a material widely used for adhesives, and is a material obtained by copolymerizing ethylene and vinyl acetate.

The liquid paraffin oil (LIQUID PARAFFIN) is also referred to as liquid paraffin, petrolatum oil (화이트), white oil, a high boiling point of petroleum oil (溜 分: 330 ~ 390 ℃) by distilling the lead after washing and decolorization ) Is obtained by filtration.

Next, as described above, after mixing a small amount of liquid paraffin oil in the urethane, phenol, EVA and melted, the material such as polyamide (Polyamide) and polyurethane (Polyurethane), which is a material of (HM: Hot Melt) well Mix, grind finely with an ink roller, and use hot melts made by VESTAMELT or POLYIMIDE RESTA.

In this case, when using an acrylic resin and a PVC resin as the material of the stone, only polyamide restorer is added as a hot melt material, and when using other materials such as PC, PS, and AS, bestamelt and polyamide restorer are added together. do.

Next, in the state in which the resins and hot melts are mixed as described above, metal salicylate (methyl salicylate) and cyclohexane (cyclohexane) are mixed to prepare a spray adhesive. Here, the metal salicylic acid is a colorless liquid having a characteristic aroma as a typical ester of salicylic acid, and is a representative compound of the cyclohexane cycloparaffins.

An adhesive surface is formed on the bottom surface of the stone 22 by spraying the adhesive 29 prepared as described above to the bottom surface of the stone 22 using an adhesive spray gun or the like.

Next, as shown in (h) of FIG. 2, hot air is provided to the stone connecting body 20 to dry the adhesive 29 applied to the stone 22.

In such an adhesive drying process, it is preferable to set the hot air temperature differently according to the constituents of the stone connecting body 20 and the components of the adhesive, and to dry it, in the case of acrylic and PVC resin, about 50 to 80 ° C, more preferably. It is preferable to dry by hot air of about 60 degreeC, and resins, such as PC, PS, and AS, are dried by hot air of about 70-100 degreeC, More preferably, about 80 degreeC.

This is because the stone 22 is deformed or the adhesive 29 is not dried well unless it is dried with a proper hot air depending on the material.

Next, when the adhesive drying process is completed as described above, by separating each stone 22 from the gate portion 24 in the stone connecting body 20 by using an ultrasonic cutter as shown in (i) of FIG. The manufacturing process of the hotfix H is completed. At this time, the hotfix (H) is in a state that is attached to a certain shape by the protective vinyl 50, or if necessary, the protective vinyl 50 can be cut and used individually or in part as a set.

In the above, the ultrasonic cutting machine is made to cut and separate only the stone 22 from the stone connecting body 20 by using ultrasonic energy of a strong energy momentarily.

The hotfix H produced by the above method is injection-molded with plastic resin so that the decorative surface of the stone 22 is formed in a polygonal shape and the bottom surface is formed in a plane, and the UV described above is applied to the decorative surface of the stone 22. In the coating method, a soft coating film 25 coated with a soft coating agent is formed, and a metal thin film 27 deposited by a vacuum deposition method as described above is formed on the bottom of the stone 22, and an adhesive 29 layer is formed thereon. It consists of a structure to be applied.

Such a hotfix (H) can be used only one or a plurality can be used as a set to form a specific pattern, the surface to which the adhesive 29 is applied to a decorative object, such as clothing, bags, etc., with a common hotfix When a high temperature heat is provided as in the method, the adhesive 29 melts and is attached to the decoration object, and then the adhesive 29 is cured, so that the hotfix H is completely attached to the decoration object to beautifully decorate the appearance of the decoration object. It becomes possible.

The hotfix according to the present invention, which is constructed and operated as described above, is manufactured by simultaneously producing a plurality of stones using acrylic resin or the like by using a single mold, while the UV coating and deposition process and the adhesive application process are performed. Hotfix manufacturing is easy and there is an advantage that can significantly reduce the manufacturing cost.

In addition, the present invention is a UV coating process using a soft coating agent in the UV coating process, so that the adhesion of the coating film and metal thin film coated on the stone is enhanced to solve the problems such as peeling off the coating surface even after long time use to improve durability There is an advantage to manufacturing a hotfix that can be.

In addition, the present invention has the advantage that by using an adhesive containing a phenol component and a liquid paraffin oil component, the hotfix is firmly attached to the decorative object to maintain a stable attachment state during washing or external impact to continuously increase the decorative effect.
