일반적으로 바다양식용으로 사용되는 부구는 부표라고도 하며 어망을 수면위에 지탱하는데 사용되는 것으로, 어망을 좌우에서 로프로 연결시키고 양측의 로프사이에 일정한 간격으로 간답대를 형성하고 상기 간답대에 부구를 부착하여 사용하게 된다.Buoys, which are generally used for aquaculture, are also called buoys, which are used to support fishing nets on the surface of the water.The fishing nets are connected by ropes from right to left, forming a pad at regular intervals between the ropes on both sides. It is attached and used.

그러나 종래의 합성수지재질로 된 통형상의 부구는 해수면의 수온상승과 하절기의 뜨거운 태양열 등에 의해 부구 내부의 공기가 팽창하여 쉽게 변형되거나 터짐으로써 사용하지 못하게 되는 문제점이 있었고, 스티로폼재질로 된 부구의 경우에는 부구의 부력을 높이기 위해 전체적으로 저밀도로 된 스티로폼(압축강도 0.5 ~ 3.0 kg/㎠)으로만 제조되었기 때문에 스티로폼이 파도 등에 의해 쉽게 마모되거나 부서지며, 또한 파도가 심하게 칠 경우에는 부구가 수중으로 유입되면서 수압에 의해 부구 표면이 뒤틀리거나 심하게 파손되며 내부에 물이 침투되어 부력이 급격히 저하되는 문제가 있었다.However, the conventional tubular ball made of synthetic resin material has a problem in that the air inside the ball is easily deformed or deformed due to expansion of the sea level and hot solar heat in the summer, and thus it cannot be used. In the case of the ball made of styrofoam material, In order to increase the buoyancy of the buoy, the styrofoam is made of low-density styrofoam (compressive strength 0.5 ~ 3.0 kg / ㎠), so that the styrofoam is easily worn or broken by waves, etc. While there is a problem that the surface of the float is distorted or severely damaged by the water pressure and the water is penetrated inside the buoyancy is sharply lowered.

본 발명은 상기와 같은 문제점들을 해결하기 위한 것으로 부구몸체의 표면을 일정온도에서 단계적으로 1,2차용융처리하여 더욱 높은 강도를 지닌 용융피막이 형성되도록 하면서 상기 부구몸체의 표면을 열수축필름으로 랩핑처리하고 용융피막과 일체로 밀착되게 부착하여 부구의 표면강도가 월등히 증가되도록 함으로써 장기간 사용시에도 일정 부력을 유지하면서 파도에 의해 부구의 표면이 마모되거나 파손되어 조각나는 것을 방지하고, 자외선 등에 의해 부구 표면이 변질되는 것을 방지하는 것에 그 목적이 있다.The present invention is to solve the problems as described above by lapping the surface of the secondary body at a predetermined temperature step 1 and 2 to form a molten coating having a higher strength while lapping the surface of the secondary body with a heat shrink film It adheres closely to the molten film so that the surface strength of the float is greatly increased, so that the surface of the float is not worn out or broken by the waves while maintaining a constant buoyancy even during long-term use. The purpose is to prevent deterioration.

이러한 목적을 달성하기 위하여 스티로폼재질로 된 부구몸체를 130 ~ 150℃로 가온된 가열로에서 1 ~ 3분간 가열하여 스티로폼재질의 부구몸체 표면이 용융되면서 0.3 ~ 0.7mm 두께로 1차용융피막이 형성되도록 하는 1차용융피막형성단계, 1차용융피막이 형성된 부구몸체를 상온에서 냉각시켜 용융피막이 경화되도록 한 다음 자외선차단제로서 카본블랙이 2 ~ 4중량% 혼합되어 제조된 열수축필름을 상기 부구몸체의 외주면 전체에 랩핑하는 열수축필름랩핑단계, 상기 열수축필름이 랩핑된 부구몸체를 160 ~ 180℃로 가온된 가열로에서 2 ~ 4분간 가열하여 상기 열수축필름이 수축되어 부구몸체에 밀착되게 랩핑되도록 하면서 상기 부구몸체 표면의 1차용융피막이 재용융되어 0.8 ~ 2mm 두께로 더 두꺼운 2차용융피막이 형성되도록 하고 상기 부구몸체 표면의 2차용융피막과 열수축필름이 일체로 부착되도록 하는 2차용융피막형성단계, 상기 2차용융피막과 열수축필름이 일체로 밀착되게 부착된 부구몸체를 상온에서 5 ~ 10분간 냉각시켜 2차용융피막이 경화되도록 하여 완성하는 냉각및완성단계를 통해 제조되는 것에 본 발명의 특징이 있다.In order to achieve this purpose, the molten body made of styrofoam material is heated in a heating furnace heated to 130 to 150 ° C. for 1 to 3 minutes to melt the surface of the molten body of styrofoam material to form a primary molten coating film with a thickness of 0.3 to 0.7 mm. The primary molten film forming step, the primary molten film is formed to cool the molten film formed at room temperature to harden the molten film and then heat shrink film prepared by mixing the carbon black 2 ~ 4% by weight as a sunscreen the entire outer peripheral surface of the secondary body Wrapping the heat shrink film wrapping step, the heat shrink film is wrapped in the secondary body in the heating furnace heated to 160 ~ 180 ℃ heated for 2 to 4 minutes to shrink the heat shrink film to wrap in close contact with the secondary body The primary molten film on the surface is remelted to form a thicker secondary molten film with a thickness of 0.8 to 2 mm and the secondary molten film on the surface of the secondary body. The secondary molten film forming step of attaching the coating film and the heat shrink film integrally, and the secondary molten film is cooled by cooling the secondary body attached to be integrally in close contact with the secondary melt film and the heat shrink film at room temperature for 5 to 10 minutes. It is a feature of the present invention to be prepared through the complete cooling and finishing steps.

상기와 같이 본 발명에 의하면 부구몸체의 표면을 일정온도에서 단계적으로 1,2차용융처리하여 더욱 높은 강도를 지닌 일정두께의 용융피막이 형성되도록 하면서 상기 부구몸체의 표면을 열수축필름으로 랩핑처리하고 용융피막과 일체로 밀착되게 부착되도록 하여 부구의 표면강도가 월등히 증가되도록 함으로써 장기간 사용시에도 일정 부력을 유지하면서 파도에 의해 부구의 표면이 마모되거나 파손되어 조각나는 것을 방지할 수 있고 자외선 등에 의해 부구 표면이 변질되는 것을 방지할 수 있는 효과가 있다.As described above, according to the present invention, the surface of the float body is wrapped with a heat-shrink film and melted while forming a molten coating film having a higher strength by forming the molten film having a higher strength by gradually melting the surface of the float body at a predetermined temperature. The surface strength of the float is greatly increased by attaching it integrally with the film, so that the surface of the float can be prevented from being worn or broken by the waves while maintaining a constant buoyancy even during long-term use. There is an effect that can prevent the deterioration.

본 발명은 표면에 용융피막이 형성되고 열수축필름이 일체로 밀착되게 랩핑되어 표면강도가 증가된 스티로폼재질의 바다양식용 부구 및 그 제조방법에 관한 것으로, 1차용융피막형성단계, 열수축필름랩핑단계, 2차용융피막형성단계, 냉각및완성단계를 통해 표면강도가 월등히 증가된 바다양식용 부구가 제조된다.The present invention relates to a molten film is formed on the surface and the heat-shrink film is integrally wrapped so that the surface strength of the styrofoam material for increased sea surface and the manufacturing method, the primary melt film forming step, heat shrink film wrapping step, The secondary molten film forming step, the cooling and the finishing step produce a marine culture ball with a much higher surface strength.

이하 본 발명에 따른 부구의 각 제조단계를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, the manufacturing steps of the float according to the present invention will be described in detail by the accompanying drawings.

1. 1차용융피막형성단계1. Primary Molten Film Formation Step

상기 1차용융피막형성단계는 도 1 및 2에 도시된 바와 같이 통상의 스티로폼재질로 된 원기둥형이나 다각기둥형 또는 구형 등으로 형성된 부구몸체(2)의 표면을 1차 가열하여 융융시키는 단계로서, 상기 부구몸체(2)를 130 ~ 150℃ 정도로 가온된 통상의 가열로에 투입하여 1 ~ 3분간 가열하여 스티로폼재질로 된 부구몸체(2)의 표면이 용융되면서 0.3 ~ 0.7mm 정도의 두께를 지닌 얇은 1차용융피막(3)이 형성되도록 한다.As shown in FIGS. 1 and 2, the primary molten film forming step is a step of first heating and melting the surface of the secondary body 2 formed of a cylindrical, polygonal, or spherical shape made of a conventional styrofoam material. Inject the secondary body 2 into a conventional heating furnace heated to about 130 to 150 ° C. and heat it for 1 to 3 minutes to melt the surface of the secondary body 2 made of styrofoam material to a thickness of about 0.3 to 0.7 mm. The thin primary molten coating film 3 having the same is formed.

상기 부구몸체(2)의 가열시 150℃를 초과하여 더 높은 온도로 가열하는 경우에는 부구몸체(2)의 형상이 원형 그대로 유지되지 않고 뒤틀리거나 한꺼번에 많은 양의 스티로폼이 융융되면서 표면이 울퉁불퉁하게 변형되는 문제점이 발생되며, 130℃ 미만으로 가열하는 경우에는 부구몸체(2)의 표면이 용융되지 않아 융융피막이 잘 형성되지 않거나 너무 얇은 두께로 용융피막이 형성되는 문제점이 발생하게 된다.When heating the secondary body 2 at a temperature higher than 150 ° C., the shape of the secondary body 2 is not maintained in a circular shape and is warped or deformed unevenly as a large amount of styrofoam melts at once. When the heating occurs below 130 ° C., the surface of the float body 2 is not melted, so that the molten film is not formed well or the molten film is formed with a too thin thickness.

한편, 상기 부구몸체(2)는 통상적으로 바다양식용 부구(1)의 부력을 높이기 위하여 압축강도가 대략 0.5 ~ 3.0kg/㎠ 정도인 저밀도 스티로폼을 사용하는 것이 바람직하다.On the other hand, the float body (2) is typically used in the low density styrofoam having a compressive strength of about 0.5 ~ 3.0kg / ㎠ in order to increase the buoyancy of the marine aquaculture floats (1).

2. 열수축필름랩핑단계2. Heat Shrink Film Wrapping Step

상기 열수축필름랩핑단계는 1차용융피막(3)이 형성된 부구몸체(2)를 상온에서 5 ~ 10분간 서서히 냉각시켜 1차용융피막(3)이 경화되도록 한 다음 자외선차단제가 2 ~ 4중량% 혼합된 상태로 제조된 열수축필름(4)을 상기 부구몸체(2)의 외주면 전체에 감싸 랩핑(wrapping)하는 단계로서, 상기 열수축필름(4)은 폴리에틸렌(polyethylene), 폴리염화비닐(polyvinyl chloride), PET(polyethylen terephthalate) 등의 합성수지를 이용하여 열수축되도록 가공한 것으로 부구몸체(2)를 전체적으로 감싸 열수축과정을 통해 부구몸체(2)의 표면에 밀착되게 부착되면서 부구몸체(2)가 마모되거나 조각나는 것을 방지하도록 되어 있으며 햇빛으로부터의 자외선 등에 의한 변질을 막기 위하여 자외선차단제로서 카본블랙이 2 ~ 4중량% 포함되어 제조되도록 되어 있다.In the heat-shrinkable film wrapping step, the secondary molten film (2) on which the primary molten film (3) is formed is gradually cooled at room temperature for 5 to 10 minutes to allow the primary molten film (3) to cure, and then the sunscreen 2 to 4 wt% Wrapping the heat-shrink film (4) prepared in a mixed state on the entire outer circumferential surface of the secondary body (2) (wrapping), the heat-shrink film (4) is polyethylene (polyethylene), polyvinyl chloride (polyvinyl chloride) , Which is processed to heat shrink using synthetic resin such as polyethylen terephthalate (PET). The entire body 2 is wrapped and adhered to the surface of the body 2 through a heat shrinking process. It is intended to prevent flying, and to prevent alteration due to ultraviolet rays from sunlight, carbon black 2 to 4% by weight is prepared as a sunscreen.

또한, 상기 열수축필름(4)은 0.2 ~ 2mm 정도의 두께를 지닌 것을 사용하는 것이 바람직하다.In addition, the heat shrink film 4 is preferably used having a thickness of about 0.2 ~ 2mm.

3. 2차용융피막형성단계3. Secondary molten film formation step

상기 2차용융피막형성단계는 열수축필름(4)이 전체적으로 랩핑된 부구몸체(2)를 2차가열하여 열수축필름(4)이 열수축되도록 하면서 부구몸체(2)의 표면을 2차 용융시키는 단계로서, 상기 열수축필름(4)이 랩핑된 부구몸체(2)를 160 ~ 180 ℃ 정도로 가온된 통상의 가열로에 투입하여 2 ~ 4분간 가열하여 상기 열수축필름(4)이 수축되어 부구몸체(2)에 밀착되게 랩핑되도록 하면서 이와 함께 상기 부구몸체(2) 표면의 1차용융피막(3)이 재용융되어 0.8 ~ 2mm 두께로 더 두꺼운 2차용융피막(5)이 형성되도록 하며 이때 상기 부구몸체(2) 표면의 융융된 2차용융피막(5)과 열수축되는 열수축필름(4)이 일체로 부착되어 더욱 견고하고 높은 표면강도를 지닌 부구(1)가 제조된다.The secondary molten film forming step is a step of secondary melting the surface of the secondary body (2) while secondary heat the secondary body (2) that the heat-shrinkable film (4) is entirely wrapped so that the heat-shrinkable film (4) heat shrink Injecting the secondary body (2) wrapped with the heat shrink film (4) into a normal heating furnace heated to about 160 ~ 180 ℃ and heated for 2 to 4 minutes to shrink the heat shrink film (4) to the secondary body (2) The primary molten coating film 3 on the surface of the secondary body 2 is remelted with the secondary molten coating film 5 having a thickness of 0.8 to 2 mm while forming the secondary molten coating film 5. 2) The molten secondary molten coating film 5 on the surface and the heat shrinkable film 4 heat-shrinkable are integrally attached, thereby making the mouthpiece 1 having a more firm and high surface strength.

상기 열수축필름(4)이 랩핑된 부구몸체(2)의 가열시 1차용융피막형성단계보다 높은 온도로 가열하여 좀더 두꺼운 용융피막이 형성되도록 하는데, 가열온도가 180℃를 초과하는 경우에는 부구몸체(2)의 형상이 뒤틀리거나 내부가 융융되어 변형되는 문제점이 발생되며, 150℃ 미만으로 가열하는 경우에는 부구몸체(2)의 표면에 형성된 1차용융피막(3)이 용융되지 않아 2차용융피막(5)이 잘 형성되지 않거나 너무 얇은 두께로 2차용융피막(5)이 형성되어 표면강도가 저하되는 문제점이 발생하게 된다.When the heat-shrink film 4 is heated, the molten film is wrapped at a higher temperature than the primary molten film forming step, so that a thicker molten film is formed. When the heating temperature exceeds 180 ° C., 2) the shape is twisted or the inside is melted and deformed, and when heated to less than 150 ℃ primary molten coating (3) formed on the surface of the secondary body (2) is not melted secondary molten coating (5) is not well formed or the secondary molten coating (5) is formed to a too thin thickness to cause a problem that the surface strength is lowered.

4. 냉각및완성단계4. Cooling and completion stage

상기 냉각및완성단계는 2차용융피막(5)과 열수축필름(4)이 일체로 밀착되게 부착된 부구몸체(2)를 가열로로부터 꺼내 상온에서 5 ~ 10분간 서서히 냉각시켜 2차용융피막(5)이 경화되도록 하여 도 3에 도시된 바와 같이 부구몸체 (2) 표면에 두께 0.8 ~ 2mm정도의 용융피막이 형성된 바다양식용 부구(1)를 완성하게 된다.In the cooling and finishing step, the secondary molten coating 5 and the heat shrinkable film 4 are integrally adhered to the secondary body 2 to be integrally in contact with each other and slowly cooled at room temperature for 5 to 10 minutes. 5) to harden to complete the marine culture floats (1) formed with a molten coating of about 0.8 ~ 2mm thickness on the surface of the float body (2) as shown in FIG.
