Description

진공성형 친환경 부표 및 이의 제조방법{Buoy and its manufacturing method}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a buoy and its manufacturing method,

본 발명은 부표에 관한 것으로, 보다 상세하게는, 대응하는 제1·2 반제품의 보호필름을 융착고정하는 진공성형 친환경 부표 및 이의 제조방법에 관한 것이다.The present invention relates to a buoy, and more particularly, to a vacuum-formed eco-friendly buoy for fusing and fixing a protective film of a corresponding first and second semi-finished products and a method of manufacturing the same.

일반적으로 부표는 부력을 이용하여 각종 수산물 양식에 필요한 시설이나 부교 등의 부상 시설물을 물 위에 띄우기 위해 사용되는 도구이며, 통상 스티로폼으로 성형한 원통형의 스티로폼의 외주면에 마대를 감아 끈으로 연결하여 사용하였다.In general, buoy is a tool used to float float facilities such as facilities and bridge for water aquaculture using buoyancy, and is usually connected to a circumference of a cylindrical styrofoam formed by styrofoam, .

그러나 스티로폼으로 제작되는 부표는 재질이 연약하고 표면이 매끄럽지 않아 조류나 파도, 작업선 등의 외부 충격이 그대로 전달되어 쉽게 부스러지고, 강한 자외선에 의해 조직이 손상되어 사용 수명이 짧아 자주 교체하여야 할 뿐만 아니라 그에 따른 경제적 손실이 증가하며, 파손된 스티로폼이 수면 위로 부유하여 심각한 오염을 일으키는 문제점이 있었다.However, buoys made of styrofoam are weak in material and smooth on the surface, so they are easily damaged by the external impacts such as algae, waves and work lines, and are damaged by strong ultraviolet rays. However, there is a problem in that the economic loss is increased, and the damaged styrofoam floats on the surface of water and causes serious pollution.

또한, 스티로폼 재질의 밀도가 낮고 표면이 거칠어서 각종 해조류 및 패류 등의 이물질이 부착되기 쉽고 스티로폼 내부에 수분이 침투되어 시간이 갈수록 부력이 급격히 저하되어 사용이 어려운 문제점이 있었다.Also, since the density of the styrofoam material is low and the surface is rough, various seaweeds and shellfish are easily adhered to the styrofoam, and the water is infiltrated into the styrofoam.

선 등록된 특허는, 상부가 개방된 폴리프로필렌 재질의 성형필름 두 개를 서로 마주보게 위치하여 내부에 폴리프로필렌폼으로 발포된 부표를 내장한 상태에서 측면테두리를 열융착시킨 후, 오븐에 넣어 가열하여 성형필름이 부표에 열융착되도록 함으로써 종래의 문제점을 해결할 수 있었다.In the registered patent, two molding films of a polypropylene material having an open top are placed facing each other, and a side edge foamed with polypropylene foam foamed inside is thermally fused, and then placed in an oven and heated So that the molded film is thermally fused to the buoys, thereby solving the conventional problems.

그러나 선 등록된 특허는, 성형필름이 부표에 열융착되도록 오븐에 넣어 가열하므로 제조공정이 복잡함은 물론 작업시간이 늘어나 생산성이 떨어지는 문제점이 있었다.However, since the pre-registered patent is heated in an oven so that the molding film is thermally fused to the buoy, the manufacturing process is complicated, and the working time is increased.

도 1은 본 발명에 따른 부표의 제조공정도이고, 도 2는 본 발명에 따른 부표의 분리사시도이다.FIG. 1 is a view showing a manufacturing process of a buoy according to the present invention, and FIG. 2 is an exploded perspective view of a buoy according to the present invention.

도 1 및 도 2를 참조하면, 본 발명 진공성형 친환경 부표(100)는, 제1 반제품(110), 제2 반제품(120)을 포함한다.Referring to FIGS. 1 and 2, the vacuum forming eco-friendly buoy 100 of the present invention includes a first semi-finished product 110 and a second semi-finished product 120.

상기 제1·2 반제품(110)(120)은, 비드폼이면서 내충격성 및 내구성이 우수한 미세화분말화의 진행이 안되는 발포 폴리프로필렌(expanded polypropylene) 또는 발포 폴리에틸렌(expanded polyethylene) 등으로 발포체(111)(121)가 형성되는데, 상기 발포체(111)(121) 내부에는 부력이 발생하는 수용공간 및 복수의 리브를 형성하여 보강할 수 있다.The first and second semi-finished products 110 and 120 may be made of expanded polypropylene or expanded polyethylene or the like having a bead form and excellent in impact resistance and durability, A plurality of ribs may be formed and reinforced in the accommodation space where buoyancy is generated in the foams 111 and 121. [

상기 발포체(111)(121)는 반원형과 사각형 및 다각형 등 성형틀의 모양에 따라 다양한 형상으로 제작이 가능하다.The foams 111 and 121 can be formed into various shapes according to the shape of the mold such as a semi-circle, a square and a polygon.

또한, 상기 발포체(111) 외주면에는 외부의 충격 및 자외선으로부터 보호하도록 소정두께로 형성되는 보호필름(112)(122)에 장착되어 융착고정된다.The outer surface of the foamed body 111 is fused and fixed to a protective film 112 (122) formed to have a predetermined thickness to protect it from external impact and ultraviolet rays.

상기 보호필름(112)(122)은 소정두께를 가지면서 외부 충격에 의한 손상을 방지할 수 있는 강도를 가져야 한다.The protective films 112 and 122 may have a predetermined thickness and strength to prevent damage due to an external impact.

다음은 본 발명 진공성형 친환경 부표(100)의 제조과정을 설명한다.The following describes the manufacturing process of the vacuum-forming eco-friendly buoy 100 of the present invention.

먼저, 도 3을 참조하면, 반제품(110)(120)을 형성하는 성형틀 중 하부 성형틀(11)에 보호필름(112)(122)을 안착시킨 후, 흡입기(미도시)로 흡입하여 하부 성형틀(11) 내부에 밀착시킨다. 이때, 상기 흡입기에서 발생하는 흡입력이 하부 성형틀(11)에 관통된 다수의 통공(11')을 통해 하부 성형틀(11) 내부의 공기를 흡입함과 동시에 보호필름(112)(122)을 흡입하면서 보호필름(112)(122)이 하부 성형틀(11) 내면에 밀착되도록 한다.3, a protective film 112 (122) is placed on a lower mold 11 of a mold for forming a semi-finished product 110 (120), and then sucked into an inhaler (not shown) And is brought into close contact with the inside of the forming die 11. At this time, the suction force generated in the inhaler sucks the air inside the lower mold 11 through the plurality of through holes 11 'penetrating the lower mold 11, and at the same time, So that the protective film (112) (122) is brought into close contact with the inner surface of the lower mold (11).

상기 하부 성형틀(11)에 보호필름(112)(122)이 밀착되면, 도 4 및 도 5와 같이, 상기 보호필름(112)(122) 내부로 폴리프로필렌(expanded polypropylene) 또는 발포 폴리에틸렌(expanded polyethylene)의 발포체를 공급한 후, 하부 성형틀(11)에 상부 성형틀(12)를 안착시켜 결합한 상태에서 제어부(30)의 제어에 따라 가열부로 성형틀을 가열하여 보호필름(112)(122)에 폴리프로필렌(expanded polypropylene) 또는 발포 폴리에틸렌(expanded polyethylene)가 융착되는 발포체(111)(121)를 형성한다.As shown in FIGS. 4 and 5, when the protective film 112 and 122 are adhered to the lower molding die 11, the expanded polypropylene or expanded polyethylene expanded into the protective film 112 and 122, the upper mold 12 is mounted on the lower mold 11 and the mold is heated by the heating unit under the control of the controller 30 to form the protective film 112 (Expanded polypropylene) or expanded polyethylene is fused to the foamed body 111 (121).

상기 발포체(111)(121)는 폴리프로필렌(expanded polypropylene) 또는 발포 폴리에틸렌(expanded polyethylene)에 자외선 차단제, 산화방지제 및 보강재 중 어느 하나 또는 하나 이상 혼합하여 형성하는데, 자외선 차단제, 산화방지제 및 보강재는 폴리프로필렌(expanded polypropylene) 또는 발포 폴리에틸렌(expanded polyethylene) 100 중량부에 대하여 20~30 중량부로 포함되도록 한다.The foams 111 and 121 are formed by mixing at least one of an ultraviolet screening agent, an antioxidant, and a reinforcing material in an expanded polypropylene or an expanded polyethylene. The ultraviolet light blocking agent, the antioxidant, 20 to 30 parts by weight based on 100 parts by weight of expanded polypropylene or expanded polyethylene.

이는 폴리프로필렌(expanded polypropylene) 또는 발포 폴리에틸렌(expanded polyethylene) 100 중량부에 대하여 자외선 차단제, 산화방지제 및 보강재가 20 중량부 이하이면 자외선 차단제, 산화방지제 및 보강재의 기능이 약하고, 30 중량부 이상이면 기능은 탁월하나 제조원가가 상승되어 경제성이 떨어지기 때문이다.If the amount of the ultraviolet ray blocking agent, the antioxidant and the reinforcing material is 20 parts by weight or less based on 100 parts by weight of the expanded polypropylene or expanded polyethylene, the function of the ultraviolet screening agent, the antioxidant and the reinforcing material is weak. But the cost of manufacturing is lowered.

또한, 상기 발포체(111)(121)가 융착되는 보호필름(112)(122) 내면에는 발포체(111)(121)와의 접촉면적을 넓혀 용이하게 융착되되도록 다수의 요철(미도시)을 형성할 수 있으며, 상기 요철은 경사지거나 돌기/홈 및 다양한 모양으로 형성할 수 있다.A plurality of protrusions and protrusions (not shown) are formed on the inner surface of the protective film 112 (122) to which the foams 111 and 121 are fused by spreading the contact area with the foams 111 and 121 so that they are easily fused And the concavities and convexities may be inclined, protrusions / grooves, and various shapes.

상기 발포체(111)(121)를 상·하부 성형틀(12)(11)로부터 분리하고, 냉각시켜 형성하는 과정을 반복하여 복수로 형성하는데, 도 6과 같이, 상기 발포체(111)(121)가 융착된 보호필름(112)(122) 단부는 내측에서 외측으로 경사지게 형성되어 발포체(111)(121)를 면접촉시켰을 때, 발포체(111)(121)가 융착된 보호필름(112)(122) 내측은 접촉되고 외측은 벌어지도록 한다.The foams 111 and 121 are separated from the upper and lower forming molds 12 and 11 and then cooled to form a plurality of the foams 111 and 121. As shown in FIG 6, The end portions of the protective films 112 and 122 to which the foams 111 and 121 are adhered are inclined from the inside to the outside so that the protective films 112 and 122 ) Inner side is contacted and outer side is opened.

여기서, 상기 상부 성형틀(12)의 모양에 따라 발포체(111)(121) 내부에는 부력이 발생하는 수용공간 및 발포체(111)(121)를 보강하는 복수의 리브를 형성할 수 있다.According to the shape of the upper forming mold 12, a plurality of ribs may be formed inside the foams 111 and 121 to reinforce the receiving space for generating buoyancy and the foams 111 and 121.

도 7과 같이, 상기 보호필름(112)(121)에 발포체(111)(121)가 융착고정된 제1·2 반제품(110)(120)을 제1·2 열접착기(21)(22)에 각각 장착한 후, 제1·2 열접착기(21)(22)를 이동시켜 제1·2 반제품(110)(120)의 대응면이 면접촉되면서 보호필름(112)(122)이 면접촉되도록 한다.The first and second semi-finished products 110 and 120 having the foams 111 and 121 welded and fixed to the protective films 112 and 121 are attached to the first and second heat bonding devices 21 and 22, The first and second thermal adhesives 21 and 22 are moved so that the corresponding surfaces of the first and second semi-finished products 110 and 120 are in surface contact with each other so that the protective film 112 .

상기의 과정으로 보호필름(112)(122)이 면접촉되면, 제어부(30)의 제어에 따라 제1·2 열접착기(21)(22)의 열선(23)접촉면에서 열이 발산됨과 동시에 발산되는 열선(23)에서 발산하는 열에 의해 대응하는 보호필름(112)(122)이 융착된다.When the protective films 112 and 122 are brought into surface contact with each other as described above, heat is radiated from the contact surface of the heat ray 23 of the first and second heat bonding units 21 and 22 under the control of the control unit 30, The corresponding protective film 112 (122) is fused by the heat radiating from the heat line (23).

이때, 상기 보호필름(112)(122)은 단부가 외향으로 경사지게 형성되어 있으므로 제1·2 열접착기(21)(22)의 열전달면적이 넓어 경사진 부분이 용이하게 용융되면서 보호필름(112)(122)이 일체화되는 부표(100)를 형성할 수 있는데, 상기 보호필름(112)(122) 중 어느 하나의 단부가 경사지게 형성될 수도 있고, 양자 모두 경사지게 형성할 수도 있다.Since the end portions of the protective films 112 and 122 are inclined outwardly, the heat transfer area of the first and second thermal adhesives 21 and 22 is wide and the inclined portions are easily melted, The protective film 112 or 122 may be integrally formed with the buoy 100. Any one of the protective films 112 and 122 may be inclined or both may be inclined.

도 8과 같이, 상기 보호필름(112)(122) 단부가 융착된 부표(100)를 제1·2 열접착기(21)(22)에서 분리한 후, 보호필름(112)(122)이 응고되어 일체로 형성되는 부표(100)를 제조할 수 있는 것이다.As shown in FIG. 8, after the buoy 100 having the ends of the protective films 112 and 122 fused is separated from the first and second thermal adhesives 21 and 22, the protective films 112 and 122 are solidified So that the buoy 100 formed integrally can be manufactured.

상기의 과정으로 제조된 부표(100)는 나무나 합성수지를 이용한 고정부재에 다수 배치되고, 부표(100)와 고정부재를 와이어와 같은 별도의 고정부재로 고정할 수 있는데, 상기 부표(100)는 보호피름(112)(122)에서 일차적으로 외부의 충격을 흡수하여 보호할 수 있으므로 제품의 품질 향상 및 수명을 연장하면서 안정감있게 사용할 수 있는 것이다.A plurality of buoys 100 manufactured by the above process are disposed on a fixing member using wood or synthetic resin, and the buoys 100 and the fixing members can be fixed with separate fixing members such as wires. Since the protective film 112 and the protective film 112 can primarily absorb external impacts, they can be used in a stable manner while enhancing the quality of the product and prolonging its service life.

또한, 부표(100) 내부에 수용공간이 형성되어 있어, 물속에 들어가 수압에 의한 변형이 발생되어도 물 위로 나오면 복원되면서 원형을 유지할 수 있으므로 안정감있게 사용할 수 있는 것이다.In addition, since the receiving space is formed in the buoy 100, if it enters the water and deformation due to the water pressure occurs, it can be restored when it comes out of the water, and the circular shape can be maintained.
