Description

MANUFACTURING OF FRP SCLUPTURE}

The present invention relates to a method for producing FRP (FRP) moldings, and more particularly, to a method for manufacturing FRP moldings, which can maintain a smooth painting operation to increase the service life.

In general, symbols installed in indoor or outdoor decoration or tourist attractions, streets, etc. are referred to as FRP moldings because they are mostly made of fiber glass reinforced plastic (FRP). For example, artificial waterfalls, streets, shops, and tourist attractions are often found in FRP sculptures.

Such FRP sculptures are completed by making sculptures with FRP and coating them with paints such as chrome on the surface. An example of manufacturing in such a manner has been disclosed in the manufacturing method of FRP sculptures in Korean Patent No. 1039616, filed and registered on December 22, 2010.

Although the sanding work for coating is performed, the sanding work is not evenly performed since the FRP surface is performed by hand work through paper work (pepa (= pepa = sandpaper)). In this case, as described above, the portion of the coating not embossed by the film called paraffin wax had many problems in life, such as peeling off the coating frequently.

In other words, the paraffin wax as described above is added to the Homica component, which is the main material of the FRP sculpture, in order to increase the adhesiveness.In this case, the paraffin wax flows to the outer surface of the FRP sculpture in the process of curing after the completion of the FRP sculpture. (Film) is formed and the coating is peeled off after the painting work, or the appearance of the coating may occur, so the paper sanding work is performed by hand to remove the paraffin wax of 0.16mm ~ 0.2mm before the painting work. At this time, since sanding is performed by hand, first, it takes a considerable time, and secondly, the appearance of the sculpture is not smooth and uneven, or the delicate sculptures are aggregated, especially the flat part of the sculpture can be removed by hand, but the paraffin wax can be removed by hand.

In the drawings, like reference numerals refer to the same or similar functions throughout the several views.

First Embodiment

1 is a view showing a manufacturing method (S100) of the FRP sculptures according to the first embodiment of the present invention by way of example, Figures 2 to 7 shows the results of performing each step of the manufacturing method (S100) of the FRP sculptures The figure shown. 2 to 7 will be described with reference to the additional element of FIG.

As shown in FIG. 1, the method (S100) of manufacturing an FRP sculpture according to the first embodiment of the present invention is performed in steps S110 to S180 to manufacture an FRP sculpture having easy sanding operation and excellent durability.

First, in step S110 according to the present invention by using any one of the materials of the sculpture mold Styrofoam, wood and clay to complete the mold of the sculpture. The engraved results are shown in FIGS. 2 and 3.

Subsequently, in step S120 according to the present invention, a release agent is applied to the mold outer surface of the sculpture completed by step S110. Subsequently, the FRP mold is completed by adding and using Homica, mat, talc and hardening material to the mold outer surface of the molded article on which the release agent is applied.

Then, in step S130 according to the present invention, after curing the FRP mold completed by the step S120, after the curing is separated between the mold of the FRP mold and the molding provided therein. The separated FRP mold is shown in FIG. 4.

Then, in the step S140 according to the present invention by applying a release agent to the inner surface of the FRP mold separated by the step S130, and then added by mixing the Homica, mat, talc and hardening material thereon to complete the FRP moldings.

Then, in step S150 according to the present invention, after curing the FRP sculptures completed by step S140, the cured FRP sculptures are separated from the FRP mold provided on the outside. The separated FRP sculptures are shown in FIG. 5.

Then, in step S160 according to the present invention performs the operation of removing the paraffin wax generated on the outer surface of the molded body separated by the step S150. The reason for removing the paraffin wax is that the coating film coated by the painting operation to be described later does not adhere properly when directly coated on the FRP sculpture.

In other words, to increase the adhesiveness of the coating. If the paraffin wax is not removed, not only the adhesiveness is degraded but also the coating may flow out of the FRP molding.

Subsequently, in step S170 according to the present invention, sand (iron) and sand powder are carried out by sanding (refining) the paraffin wax coated by the step S160 using a pressure injector filled with at least one material.

Here, the sanding is performed through the pressure injector is shown in FIG. The pressure injector 100 illustrated in FIG. 6 includes a pressure tank 110, a compressor 120 filling air and applying pressure to the air, and an air gun 130 connected to the pressure tank 110 and the compressor 120.

By adjusting the control valve of the air gun 130, at least one material of the iron powder and stone powder sprayed by the pressure and the air at the same time or any one of the paraffin wax layer generated in the FPR sculpture 200 ( 210 is strongly sprayed toward. In this case, the paraffin wax layer 210 is finely, roughly and evenly cut to the curved or fine parts.

In this case, it is preferable to inject a material and air filled in the pressure injector several times by varying the sanding interval (d) between the paraffin wax layer 210 and the air gun 130 provided with the pressure injector 100. In addition, since the pressure injector 100 is injected at a discharge pressure 140 of 13 to 17 kg / cm 2, the sanding operation may be performed so that the fine, rough and even surface of the FRP sculpture 210 is bent to a minute or minute portion. In this way, the outer surface 120 of the more accurate FRP sculpture will be finely rough and even.

However, even when injected at a discharge pressure 140 of 13 to 17 kg / cm 2, the correct paraffin is achieved if the distance d between the outer surface 210 and the air gun 130 of the FRP sculpture 200 located in front is not adjusted. Wax removal sanding may not be performed. Even in this case, the sanding gap d between the outer surface 210 of the sculpture and the air gun 130 is primarily maintained at an interval of 90 to 1 m and 20 cm, and is secondly maintained at an interval of 45 to 55 cm. Is preferred.

When the injection is made by differently divided by the first and second sanding intervals as described above, a more accurate paraffin wax removal sanding operation is performed, the accuracy of the outer surface of the fine, rough and even fine to the curved or fine parts ( 210 will be able to make.

In addition, in order to achieve the best painting work, it is necessary to sand (remove) paraffin wax to a certain thickness. That is, it is necessary to sand (remove) the thickness of 0.2.mm to 0.16mm of the paraffin wax 210 formed on the FRP sculpture.

In this case, when the injection is controlled by the sanding interval and the discharge pressure described above, the FRP sculptures having a thickness of 3mm to 3.2mm can be removed by the pin pin wax and the FRP sculptures can be sanded to a thickness of 2.8mm to 3.04mm. .

Finally, in step S180 according to the present invention after the finely rough and even sanding is completed to the curved or fine parts of the FRP sculpture by the step S170 to perform the operation of coating the coating film on the outer surface of the shaved sculpture body. . In this case, the coating may be a chrome coating having various colors, but is not limited thereto. The result of the painting operation is shown in FIG.

As such, when steps S110 to S180 are performed, the manufacture of the FRP sculpture is completed.

Second Embodiment
