Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. This embodiment is provided to more completely describe the present invention to those with average knowledge in the industry.

Accordingly, the shape of the constituent elements expressed in the drawings may be exaggerated to emphasize a more clear description.

It should be noted that in each drawing, the same configuration may be indicated by the same reference numeral. In addition, detailed descriptions of functions and configurations of known technologies determined to unnecessarily obscure the subject matter of the present invention may be omitted.

First, looking at the pot stand structure according to an embodiment of the present invention through FIGS. 1 to 3 are as follows.

In this embodiment, the pot stand is a base body 10 molded and manufactured from natural rubber, silicone or synthetic resin material, a reinforcing core material 20 coupled to the bottom surface for reinforcing durability of the base body 10, and the In order to prevent the external exposure of the reinforcing core material 20, the bottom coating layer 30 made of a silicone or urethane component coated on the bottom of the pedestal body is formed.

In addition, a fitting groove 11 for fitting and coupling of the reinforcing core material 20 made of a metal material is formed on the bottom surface of the pedestal body 10, and the upper surface of the pedestal body 10 makes contact with the bottom surface of the pot. It can be seen that a plurality of protrusions 12 are provided to protrude to minimize.

The manufacturing process of the present invention pot holder constituting such a configuration will be described with reference to the flow chart of FIG. 4. First, the base body 10 is molded and manufactured using a molding mold.

That is, at this time, the base body 10 is molded by selecting any one of a melted natural rubber, silicone, or synthetic resin material, putting it into a molding mold, and curing it for a certain period of time, and the bottom of the molded base body 10 The fitting groove 11 is formed.

Thereafter, a work of reinforcing the shape of the pedestal body 10 is performed by inserting the reinforcing core material 20 in the form of a metal ring into the bottom fitting groove 11 of the pedestal body 10 having the molded shape.

In addition, a coating operation for forming the floor coating layer 30 on the bottom surface of the pedestal body 10 is performed. In this case, by spraying the silicone or urethane coating material evenly using a spray or applying the coating material to a uniform thickness using a tool such as a brush to form the floor coating layer 30, external exposure and separation of the reinforcing core material 20 is prevented. It will be able to show a preventive effect.

In the pot stand of the present invention completed through such a manufacturing process, the pot stand formed of rubber or synthetic resin material is reinforced by the reinforcing core material 20 to enhance shape support and durability, so deformation and damage are prevented during use. Can be.

In addition, due to the formation of the floor coating layer 30, the reinforcing core material 20 can be protected and a slip phenomenon with the table bottom can be prevented, thereby improving the convenience of use.

Meanwhile, FIG. 5 shows a cross-sectional structure of a pot stand according to another embodiment of the present invention, and a protective coating layer 13 for preventing surface contamination is formed on the upper surface of the stand body 10. At this time, the protective coating layer 13 is a sterilizing material, nano silver, thermosetting elastomer for preventing heat deformation, SBS polymer for strengthening adhesion, silicone, polyglycol, titanium dioxide for improving durability and strength, and avocado oil for preventing discoloration and oxidation. , Polyolefin and paraffin wax are mixed.

As an example, nano silver 10 to 30% by weight, thermosetting elastomer 10 to 30% by weight, SBS polymer 10 to 20% by weight, silicone 10 to 20% by weight, polyglycol 1 to 10% by weight, titanium dioxide 1 to 10 It is preferable that the mixing is made in a ratio of 1 to 10% by weight of avocado oil, 1 to 5% by weight of polyolefin, and 1 to 5% by weight of paraffin wax.

In particular, polyolefin is a polymer compound having excellent transparency and activates a thermosetting elastomer, and paraffin wax functions to maximize the surface lubricity of the coating layer. In the case of forming the protective coating layer 13 as described above, the protrusion is not formed on the upper surface of the pedestal body 10. In addition, in the case of forming the protective coating layer 13, the pot stand can be manufactured through the same process as in FIG. 6.

That is, at this time, the protective coating layer 13 constituting the mixed composition is formed on the upper surface of the molded base body 10 by a spray spray method, and UV light is applied to homogenize the protective coating layer 13 The first UV light irradiation step of irradiating for 10 minutes, a roller pressing step of pressing using a pressing roller so that the protective coating layer 13 as a whole has a uniform thin film thickness, and the protective coating layer 13 having the roller pressing A second UV light irradiation step of increasing the bonding force according to activation of the mixed component by irradiating the UV light for about 5 minutes once again, and the protective coating layer 13

By cooling the formed pedestal body 10 at a temperature of 5 to 10°C for 5 to 10 minutes, a cooling step of improving durability is sequentially performed.

When such a process is carried out, the protective coating layer 13 is heated in the first UV light irradiation step to achieve a stable state due to homogenization between the mixed components, and in this state, a uniform thin film thickness is achieved through the roller pressing step. The protective coating layer 13 is formed.

Thereafter, the bonding force between the components of the coating layer is increased through the secondary UV light irradiation process to form an integrated coating layer, and the durability and strength are improved by curing the protective coating layer 13 through the cooling process. The occurrence can be prevented.

When the formation of the protective coating layer 13 is completed, the reinforcing core material 20 is inserted into the bottom fitting groove 11 of the pedestal body 10, and then the bottom coating layer 30 is formed on the bottom surface of the pedestal body 10. Production of the product is completed by shikim.

Therefore, the pot stand of the present invention made through such a process improves the usability of the product due to the protective coating layer 13 on the upper surface with enhanced sterilization, pollution prevention and functionality, and the bottom coating layer ( It can be seen that the slip phenomenon can be prevented during the use process due to 30).

And although a specific embodiment of the present invention has been described and illustrated above, it is obvious that the technique of manufacturing a pot stand of the present invention can be variously modified and implemented by those skilled in the art.

For example, in the above embodiment, the shape of the pot stand is shown through FIG. 1, but the shape of the pot stand can be molded and manufactured in various forms as shown in FIG. 7.

Therefore, such modified embodiments should not be individually understood from the technical spirit or scope of the present invention, and such modified embodiments should be included within the appended claims of the present invention.
