BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram illustrating a process sequence for a method of manufacturing a hot-stamping stone according to the present invention. FIG.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, it should be understood that the following embodiments are provided so that those skilled in the art can understand the present invention without departing from the scope and spirit of the present invention. It is not.

FIG. 1 is a view illustrating a process sequence of a method of manufacturing a hot-stamp stone according to the present invention.

Conventionally, an acrylic resin or a polyamide resin, which is a main component of an adhesive (hotmelt), is made into a powder form and applied to the bottom face of a hot-fix stone by a vertical drop method. However, this method is difficult to control the amount of powder, It is also impossible to control the adhesive strength.

Unlike the conventional method, in the present invention, a method of liquefying an acrylic resin or a polyamide resin (hereinafter referred to as "acrylic or polyamide"), which is a hot melt, with an organic solvent in a powder state is used. As the organic solvent to be used at this time, general materials such as thinner and kerosene may be used. The liquefied acrylic or polyamide can be adjusted in the amount of application according to the number of times of spraying when it is applied to the bottom surface of the hot-fix stone by a spraying method as described later.

On the other hand, if the mixing ratio of the organic solvent to the powder of acrylic or polyamide is controlled, the adhesive strength of the adhesive can be controlled. The more the content of the organic solvent is, the lower the adhesive strength. Therefore, You can adjust it.

Next, the liquefied acrylic or polyamide is heated and kept constant at a temperature of 20 to 25 占 폚. When the temperature is maintained at a constant temperature of 20 to 25 캜, it is possible to prevent the aggregation of liquefied acrylic or polyamide upon spraying on the bottom face of the hot-fix stone, Or the effect that the polyamide is completely liquefied can be seen.

Next, a primer (for example, a colorless primer) is applied to the bottom surface of the hot stone. The primer improves the adhesion of acrylic or polyamide to the bottom of the hot-fix stone. Since the primer is commonly used in conventional hot-fix stone adhesives, a detailed description thereof will be omitted.

After the application of the primer, the liquefied acrylic or polyamide is uniformly applied to the bottom surface of the hot-fix stone while maintaining the temperature at 20 to 25 캜. At this time, it is preferable to apply liquefied acrylic or polyamide by a spraying method using a spray gun or the like. When the spraying method is used, there is an advantage that liquefied acrylic or polyamide can be adjusted and applied by a desired amount. As described above, when the temperature of the liquefied acrylic or polyamide is kept constant at 20 to 25 占 폚, it is possible to prevent the aggregation of liquefied acrylic or polyamide upon injection into the bottom face of the hot-fix stone, The effect of completely liquefying acrylic or polyamide which has not been completely liquefied by the solvent can be seen.

Next, the acrylic or polyamide is cured by heating the bottom portion of the hot-stamped stone to which liquefied acrylic or polyamide is applied to a temperature of 140 to 160 캜. At this time, if heating is performed for about 2 to 3 seconds, acrylic or polyamide is completely cured. In a large number of hot stone manufacturing processes, it is desirable to cure while transferring through a heat drying conveyor in terms of productivity improvement. After the acrylic or polyamide is completely cured, the product is completed by a washing step.

On the other hand, when using the hot stone stone product of the present invention completed through the above steps, the bottom portion of the hot stone is heated for 2 to 7 seconds at 120 to 160 DEG C using an iron, a hot press or a styler Hotfix Stone Since the cured acrylic or polyamide is partially dissolved in the bottom portion of the stone, the hot fix stone may be attached to the decorative object (various accessories, clothes, hair, etc.).

Since the hot-melt of the hot-melt of the present invention is controlled by the mixing of the hot-melt of acrylic or polyamide cured to the bottom of the hot-melt of the present invention with the organic solvent, compared with the conventional hot- So that it is not maintained in a completely fixed state with respect to the decorative object. Therefore, when the hot stone of the present invention attached to the decorative object is removed with appropriate force, it is removed without leaving any adhesion mark or foreign matter. Here, the appropriate force is proportional to the adhesive strength (or adhesive force) which varies depending on the amount of the organic solvent mixed with acrylic or polyamide, and for example, 20 to 30% by weight of the organic solvent is contained relative to 100% The hot-fix stone is adhered to the decorative object with an adhesive strength so that the decorative object can be peeled off without bending the surface of the decorative object without being arbitrarily detached from the decorative object by its own weight.

As described above, the hot stone produced according to the present invention is adhered to decorative objects such as various accessories, clothes or hairs, and has an adhesive force enough to easily remove it with bare hands if necessary. Accordingly, when a hot stone is attached to a decorative object and the hot stone is attached to the same decorative object in a different design, it is necessary to remove the first hot stone without adhering trace or damage, Stone can be attached.

In addition, the hot stone of the present invention can be attached to various parts of the human body including hair, and can be used after removing the adhesive after heat treatment. There is an advantage that it is possible.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, This is possible.
