Description

Decorative icicles and its manufacturing method {A method of ornamental icicle}

The present invention relates to a method for manufacturing a decorative icicle by using a transparent plate made of acrylic resin, methacryl resin, and the like, and more particularly, to a method for manufacturing a decorative icicle, which is very simple and can significantly reduce manufacturing costs.

In general, icicles are stick-shaped ice that freezes the water flowing down the roof eaves in the cold winter season, and makes a good mood.

Such decorative icicles are mainly produced by injection molding a transparent resin, but in this case, not only a considerable cost is required for the production of the injection mold, but also a plurality of molds are required to manufacture icicles having different shapes in succession. There have been closures such as huge costs for the production of the mold.

Of course, in the case of producing a large amount of icicles, injection molding is preferred, but since the shape and size are formed differently according to the place and purpose for which the decorative icicles are installed, it is not suitable for mass production of icicles.

In some cases, the transparent plate can be processed into icicle shape by hand, but in this case, it takes much time to produce icicles, and in order to obtain the effect of transparent ice, the surface treatment of icicles must be performed very precisely. Closure occurred, such as the efficiency of remarkably decreased.

The present invention has been made in view of the above problems, and an object thereof is to provide a decorative icicle and a method for manufacturing the same, which are very easy to manufacture icicles and can reduce a considerable production cost.

Features of the present invention for achieving the above object, the step of cutting the transparent plate made of synthetic resin into the appearance of icicles; Cutting and polishing the outer surface of the cut transparent plate to form an icicle shape; Coating a transparent synthetic resin on the outer surface of the molded icicle; Firstly curing the coated icicles by applying heat at 40 to 70 ° C. in a tank filled with nitrogen; It can be achieved by a method for producing a decorative icicle, characterized in that the icicle is completed by the second step by applying a heat of 110 ~ 130 ℃ to the first cured icicle.

Hereinafter, with reference to the accompanying drawings, preferred embodiments for achieving the above object will be described in detail.

The transparent plate 1 made of synthetic resin is cut into a shape corresponding to the outer shape of the icicle 2. The transparent plate 1 uses a synthetic resin such as acrylic resin or methacrylic resin having excellent transparency.

The cutting operation of the transparent plate 1 may automatically cut the shape of the desired icicle 2 by inputting an external picture of the icicle 2 into a computer in advance, or may be automatically cut using a pattern of the figure. As it is, the cutting operation of the transparent plate 1 can be completed quickly and simply, and mass production is possible even if the shapes of different icicles 2 are cut.

Then, when the outer shape is cut, the outer surface of the transparent plate 1 is cut and polished to complete the shape of the icicle 2. This molding step also does not take much time because the cutting and polishing of the edge portion and the curved portion little by little in the state that the appearance of the icicle 2 is cut in advance.

Subsequently, a transparent synthetic resin is coated on the outer surface of the completed icicle 2 to keep the surface smooth.

The coating synthetic resin is also preferably formed of the same material as the transparent plate 1 using a synthetic resin such as acrylic resin or methacrylic resin having excellent transparency.

When the acrylic resin or methacrylic resin is coated on the outer surface of the completed icicle 2 as described above, the work is very simple and does not require a separate surface treatment. There is an advantage such as to significantly reduce the time.

In addition, when the transparent resin is coated, the surface is not only formed very smoothly, but also has a slight flow, so that the texture and appearance of the icicle (2) are very similar to the icicle (2) that freezes as water flows. The advantage is that the model can be almost completely reproduced.

In particular, since the resin of the same series as the transparent plate 1 is coated, when the resin is applied, the surface of the transparent plate 1 is slightly melted and polymerized with the resin to change into a compound having a high molecular weight, thereby causing fine cracks and internals. Bubbles are generated in the air to create a perfect ice shape.

Subsequently, when the coating is completed, the icicle (2) molded product is introduced into a tank filled with nitrogen, and subjected to primary curing by applying heat of 40 to 70 ° C.

Subsequently, when the secondary hardened by applying heat of 110-130 degreeC to the primary hardened icicle 2, the decorative icicle 2 is completed.

The reason for hardening stepwise in two times is to apply high heat after applying primary low heat to prevent the cracking of the surface when giving too strong heat from the beginning to the coated gel resin. It is preferable to add and harden secondary.

Even if the step is cured in this way, a minute crack is formed in part of the coated portion. However, these cracks are very similar to the cracks finely formed in the crystals of ice, so that they form a shape close to the original shape of the icicle 2, so that a high quality decorative icicle 2 can be obtained.

In addition, when cutting the transparent plate 1, the outer shape may be cut so that a plurality of icicles 2 are continuously formed, but in some cases, the outer shape of the icicles 2 having different sizes and shapes may be cut to form an adhesive. After continuous bonding, and cutting and polishing, the transparent synthetic resin is coated and cured to produce a decorative icicle 2 in which several icicles 2 are continuously bonded.

Of course, in this case, it is a matter of course that a flat adhesive portion 2a is formed on the upper side of the icicle 2 and configured to be adhered with an adhesive. In some cases, the cut icicle 2 is cut and polished and then adhered and coated. can do.

In this case, when cutting and cutting the transparent plate 1, the external figure of the icicle 2 may be appropriately arranged to cut the cutout of the transparent plate 1 to minimize the amount of material used. There is an advantage such as the line formed by the adhesive portion (2a) is covered by the resin during the coating operation is not displayed.

According to the present invention as described above, the surface of the icicle (2) having a variety of sizes and shapes using an automatic cutting machine automatically cut, cut and polished to shape the outer shape and then coated with a transparent resin, the surface treatment Has the advantage that it is completed quickly, and then hardened to complete the decorative icicle (2), so that the working method is very simple to increase the efficiency of the work and at the same time maintain the overall manufacturing cost at a low cost Perfectly resolved will be able to maximize the external competitiveness of the decorative icicle (2).

In addition, since the icicle (2) having a variety of shapes and sizes by the automatic cutter can be molded, according to the place and purpose of the decorative icicle (2) can be easily manufactured and installed in the appropriate shape, Since there is no need to manufacture injection molds, the cost of making icicles can be minimized, and at the same time, the shape of the icicles can be reduced due to the flow of the resin coated on the outside of the icicles, the smoothness of the surface, and the minute cracks such as ice crystals generated during curing. Because it is able to reproduce the model closest to it perfectly, it can provide decorative icicle that can feel high quality.
