Description

Non-foaming urethane solid relief and manufacturing method thereof {A non-forming urethane projection carving and manufacturing method therefor}

The present invention is a natural wood, stone or metal material, such as silver, copper, tin, gold, or alloys thereof, such as molded in a metal material, such as the texture, weight, color and excellent three-dimensional memorial boats, sculptures and The present invention relates to a non-foamable urethane solid relief product and a method for manufacturing the same, and in particular, the present invention is based on a three-dimensional relief wooden sculpture carved in the same shape as a memorial boat, sculpture, etc. First, each part divided by the dividing line arbitrarily dividing the entire surface of the UTO layer was sequentially coated, and then FRP was applied to the surface corresponding to the coated UTO layer to form an input hole and a flange. Repeat the process of forming the FRP support frame to form the UTO layer and the FRP support frame divided on the wooden pole surface, and then divide and disassemble the FRP support frame around the dividing line Then, only the covered UTO layer is removed to secure a space between the FRP support frame and the wooden die. Then, the silicone cured at room temperature is injected and cured in this space. Then, the other FRP support frame is dismantled, and the soil is removed. After securing the space part, injecting and curing silicon into the space part to form a silicon upper mold, forming a silicon mold to be divided and joined, and then dismantling and separating the FRP support mold and the silicon mold to remove the internal wooden mold. After removing, apply the pigment of the unique color such as wood and metal to the inner surface of the divided silicone mold and barrier treatment and inject urethane to form a three-dimensional relief with the required color on the surface of the relief such as memorial boat, and then demold Process to grind the surface of non-foamed urethane relief molded in three-dimensional relief state to give three-dimensional contrast. It has the same texture, weight, and color as that of molded wood or stone, or metal such as silver, copper, tin, or alloys thereof, or three-dimensional sculpture. It will be able to provide large quantities of three-dimensional non-foaming urethane reliefs such as commemorative boats and sculptures in which the aesthetics are expressed in the same way as natural materials.

In general, it is common that various plaques, memorial boats, reliefs, or plate-shaped memorial boats, such as commemorative boats or cultural assets of various events, conventions, and tourist attractions are widely used.

However, in manufacturing such various memorial boats, in the case of expensive plaques, the memorial boats are formed by molding metal materials such as metals such as bronze, silver, tin, or alloys thereof, or carving wood, stone, etc. When manufacturing commemorative boats, etc. using the former metal materials, the weight and weight are excellent due to the physical properties and properties of the metal material, and the solid texture is exerted for a long time. A memorial boat or a three-dimensional relief can be obtained, but the material itself is expensive and there is a problem in the material that is difficult to handle or process. Therefore, the equipment for processing and manufacturing it is complicated and requires a lot of equipment costs. Except for the case, there was an economic burden that could not be generalized. As a result of the reprocessing of expensive metal commemorative vessels by chemical or electroplating methods, not only the burden of manufacturing cost rises, but also its plating process is a significant pollution-causing hazardous work, resulting in a poor and unsanitary working environment. It showed various defects such as one.

In the case of commemorating boats or three-dimensional reliefs made of the latter stone or wood, mass production is impossible due to the manual production of stone and wood by hand carving letters or figures. It requires a very skilled technique and has a problem that cannot be mass-produced due to many difficulties and limitations in mass production, and it is also a method for mass-producing memorial boats such as wood or stone. In some cases, a letter or figure may be transferred or printed by a printing method such as screen printing to produce a commemorative boat that expresses the same pattern or character, but this may cause the character or figure to be represented by a printing method such as printing on a plane. By obtaining the effect and texture of the three-dimensional or relief form It is difficult to expect high-quality products due to deterioration in decoration and aesthetics, and in the case of flat transfer or screen printing, the printing layer is easily peeled off, and the memorial boat is used. Since the appearance is easily damaged, there are defects such as a short lifespan, and the material is easily damaged by an external impact due to the material properties.

Therefore, in order to remove the difficulties and limitations of productivity, which are weak points such as metals, wood, and stone, conventionally, molds were used to produce commemorative boats or three-dimensional reliefs using materials such as synthetic resins, for example, FRP, Homica, etc. On the other hand, since the product itself is light, it is profound and hard to expect any texture or effect, and there is a problem that it is difficult to expect a high quality product because of defects that are easily broken in terms of materials.

Therefore, the present invention is to solve the defects of the memorial boat of the above-mentioned materials, such as those cast in natural wood, stone or metal materials such as silver, copper, tin or metal materials such as alloy materials thereof in a simple manufacturing process or The purpose is to provide a large amount of three-dimensional reliefs made of a non-foaming urethane having the same heavy texture, weight, and color as the natural materials, such as direct three-dimensional engraving.

In addition, the present invention is excellent in durability due to the physical properties and properties of the non-foaming urethane material itself, excellent durability and form a precise three-dimensional pattern and letters to express the decorative molding beauty and aesthetics as natural materials, excellent appearance and decorative Another purpose is to provide a large amount of non-porous polyurethane reliefs such as this excellent memorial boat and sculpture at a low cost.

In addition, the present invention reproduces the elaborately carved wooden form as a basic form to obtain a memorial boat or three-dimensional relief of the elaborate state, it is easily applied to the memorial boat and plaques of various competitions, as well as the memorial boat or decorative reliefs that require decoration Another aim is to be able to obtain the various types of three-dimensional monuments or decorative reliefs required.

The present invention for achieving the above object is an FRP support frame molding process for forming an FRP support frame made of FRP around the basic wooden mold, a silicone molding frame molding process formed by the FRP support frame and the wooden mold, and the silicon It is made of a combination of a three-dimensional relief-shaped foam-free polyurethane molded product formed by a molding die, when explaining the embodiment according to the accompanying drawings as follows.

After binding and binding with the lower FRP support frame 6 (FIG. 2A), the upper part of the die 1 is exposed to the inside of the upper FRP support 4, and the die 1 is the lower soil layer. After securing the upper space portion 9 formed in the state supported by 5), the silicone (RTV) cured at room temperature through the input hole 4 'of the FRP support frame 4 in the space portion 9 (RTV). After the silicon upper mold 10 is primarily formed by injecting, filling, and curing the silicon rubber), the upper silicon mold 10 is completely cured (FIG. 2 (b) and (d)). Upper and lower back FRP supports (4) , (6) are dismantled, and the lower FRP support frame (6) of the other one of the upper and lower FRP support frames (4) and (6) is also peeled off, and the dividing line of the wooden die (1) embedded therein ( 2) The remaining portion of the lower soil layer (5) is completely removed to secure the space portion 12, and then a mold release agent is applied to the upper surface of the already formed silicon upper mold 10 and the mold 1 to the upper silicon mold 10 ) And a mold release layer 11 so that the die 1 and the silicone lower mold 13 to be described later can be separated smoothly, and then the lower FRP support frame 6 is sealed with the upper FRP support frame 4. The silicon lower mold 13 by injecting, filling, and curing the silicon through the injection hole 6 'in the inner space 12 with the die 1 formed in the lower FRP support frame 6; Molding, but the injection tube 14 is embedded in the injection hole (6 ') to insert the end of the injection tube 14 in close contact with the die 1, close to the state, and then through the surrounding space After the silicon is injected into the space 12 and cured, the silicon lower mold 13 is formed in the lower FRP support frame 6 so that the injection tube 14 protrudes to the outside. After completely hardened, dismantle the upper and lower FRP support frames (4) and (6) and remove the dies (1) between the upper and lower molds (10) and (13) at the room temperature without requiring a separate heating process. The upper and lower molds 10 and 13 having the cavity 10 'and 13' of the required shape are fixed in the upper and lower FRP support molds 4 and 6 to be molded.

In this process, the soil layer 3, 5 is formed between the upper and lower portions of the upper and lower FRP support frames 4 and 6 and the upper and lower portions of the die 1, which are made of FRP. ), (5) shows lubrication or excellent mold release function, so that the upper and lower FRP support frame (4), (6) is completed, and the upper and lower FRP support frame (4) and (6) When dismantled and removing the soil layer (3) and (5), which had been covered around the die (1), the state of contact with the surface of the die (1) or the surface of the FRP support frame (4) and (6) is not good. As it exists in the adhesive state, when the soil layer (3) and (5) are removed, the soil layer (3) and (5) remain on the surface of the FRP support frame (4), (6) or die (1). It can be easily peeled off and removed to keep the carving surface of the die (1) clean and clear in its original state, by injecting and filling-hardening the silicone to form the upper, lower molds (10) and (13). Silicone upper and lower molds in operation (10), (13) The shape or shape of the three-dimensional grooves 10 'and 13' is perfectly shaped into the shape of the shape of the solid shape opposite to the three-dimensional pieces of the wooden mold 1, and the silicon-like, lower molds 10 and 13 are When molding sequentially, the upper and lower FRP support frame which becomes FRP by applying a release agent to the surface of the upper silicon mold 10 and the mold 1 formed beforehand to form a release layer 11 therebetween. 4), (6) to obtain a silicon phase, the lower mold 10, (13) that is completely separated up and down, wherein the silicon used is a simple working condition at room temperature by using the RTV silicone cured at room temperature Under the silicon phase, the lower mold 10, 13 will be obtained.

(Polyfoamable Urethane Resin Molding Process)

This process as shown in Figure 3 is a molding process for obtaining a foam-free polyurethane three-dimensional relief 100.

Representing on the surface of the non-porous polyurethane three-dimensional relief 100 on the inner circumferential surface of the three-dimensional groove (10 ', 13') of the silicon phase, the lower mold (10), (13) formed by a series of processes as described above After applying the pigment of the desired color, for example, metal powder such as gold powder, silver powder, brass powder, or pigment of stone or natural color of stone or wood, the barrier treatment is applied, and then the upper and lower FRP support frame (4), (6) by fastening and applying a release agent between the upper and lower silicon molds 10 and 13, and then the upper and lower silicon molds through the injection tube 14 formed in the lower FRP support frame 13 When the foamless polyurethane liquid is gradually injected into the three-dimensional grooves 10 'and (13') of (10) and (13), the air present in the three-dimensional grooves 10 'and (13') is not foamed. It is discharged to the outside while being pushed up to the injection pipe 14 and is discharged to the outside. Filled and filled without bubbles in the silicon molds 10 and 13, and pigments in the three-dimensional grooves 10 'and 13' of the upper and lower silicon molds 10 and 13 are colored and painted on the front and back surfaces. The layer-free foamed polyurethane three-dimensional relief 100 formed on the three-dimensional surface is molded in a state where bubbles are not generated therein, and then cured at room temperature, and then the upper and lower FRP support frames (4). (6) was dismantled and demolded the foamless polyurethane three-dimensional relief article 100 in which the paint layer 101 was formed in the desired color on the front and back surfaces, and the powdery pigment was sprayed and ground on the front and back surfaces to form the foamless polyurethane three-dimensional relief article. Fig. 100 shows the three-dimensional contrast portion 102 formed in the groove formed by the inherent texture of the wood formed by the irregularities on the front and back surfaces or the wooden die 1, so that the pigment is added to the groove portion thereof to give the effect of the three-dimensional contrast. Foam-free polyurethane three-dimensional relief 100 of the three-dimensional state such as four It will be good.

In the present invention made by such a process, the wooden mold (1) is a basic mold for forming the foam-free polyurethane three-dimensional relief 100, due to the physical properties of the relatively easy engraving or processing of the three-dimensional pattern of the yin and yang, It can be easily engraved or engraved on the front or rear, such as figures and characters, as needed, and at room temperature curing to form a foam-free polyurethane three-dimensional relief (100) as a basis of the elaborately carved wooden (1) The upper and lower molds 10 and 13 are formed by using silicon, and the upper and lower molds 10 and 13 are also molded into an elaborate form opposite to the shape represented by the die 1. Next, by forming the three-dimensional shape of the three-dimensional relief, such as three-dimensional reliefs, sculptures, patterns, or character shapes expressed in the wooden mold 1 by the upper and lower molds, to form a foam-free polyurethane three-dimensional relief 100 It is possible to obtain three-dimensional reliefs of various shapes with fine shapes and characters on both the front and back surfaces (100 ') and (100 ″) of the foam-free polyurethane reliefs (100), and the upper and lower molds of silicone ( 10), (13) of the three-dimensional groove (10 ', 13') of the coating layer 101 and the three-dimensional paint showing the same texture as the original color of metal, wood, stone, etc. By forming the contrast portion 102, it is possible to obtain a three-dimensional relief 100 that is relatively heavy after molding and heavy in appearance and touch.

On the other hand, in the above, the foam-free polyurethane three-dimensional relief 100 is formed by the upper, lower mold 10, 13 of the room temperature curing divided into two sets around the upper and lower dividing lines 2 of the die (1) One example has been described as an example, but the present invention is not limited thereto, and a sculpture or a shape having many frostbite, a bust of a human body, and an asymmetric unevenness is simply sculpted in a wooden shape, and the number of UTO layers and FRP supporting frames is increased along the dividing line arbitrarily divided therefrom. While the Uto layer and the FRP support frame are detachable and bonded together, and the Uto layer is sequentially removed while injecting the silicon at room temperature, the silicone mold is divided into a plurality of molds. Even if the bust of the human body, asymmetrical irregularities are difficult to restore or reproduce a lot of three-dimensional sculptures can be easily and easily expressed in three dimensions.
