[규칙 제26조에 의한 보정 06.02.2017]　실란트용 카트리지[Revision based on Rule 26 06.02.2017] 카트리지 Sealant cartridge
본 발명은 실란트용 카트리지에 관한 것으로서, 특히 포장된 실리콘 접착제 등의 실란트가 외부 습기에 의해 특성이 변화되는 것을 방지할 수 있는 실란트용 카트리지에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealant cartridge, and more particularly, to a sealant cartridge which can prevent a sealant such as a packaged silicone adhesive from changing its properties due to external moisture.
건축 분야에서 창틀 및 줄눈의 방수 등을 위해 실리콘(silicone)계 실란트, 폴리 우레탄계 실란트 또는 폴리설파이드계 실란트, UV 실란트, UV 접착제 또는 UV 코팅제 등의 공기 중의 수분에 의해 경화하는 실란트가 널리 사용되고 있다. 상기에서 실리콘계 실란트(이하, 실리콘이라 칭함)는 유기기를 함유한 규소(organosilicone)와 산소 등이 화학결합으로 서로 연결된 폴리머로 반도체 재료인 규소(silicon)와 다른 물질이다. 상기에서 실리콘은 유기성과 무기성을 겸비한 독특한 화학재로서 오일(oil), 고무(rubber) 및 수지(resin) 등의 여러 형태로 구분된다. 이러한 실리콘은 건축 분야뿐만 아니라 절연체, 접착제, 브레이크액, 방수액, 유방 성형 재료 및 윤활유 등으로 산업분야에서 필수적인 고기능 재료로서 사용되고 있다.In the construction field, a sealant which is cured by moisture in the air such as silicone sealant, polyurethane sealant or polysulfide sealant, UV sealant, UV adhesive, or UV coating agent is widely used for waterproofing window frames and joints. The silicone sealant (hereinafter referred to as silicon) is a polymer in which an organic group-containing silicon (organosilicone) and oxygen are connected to each other by chemical bonds, and are different from silicon, which is a semiconductor material. In the above, silicon is a unique chemical having both organic and inorganic properties, and is classified into various forms such as oil, rubber, resin, and the like. This silicone is used as an essential high performance material in the industrial field as an insulator, an adhesive, a brake fluid, a waterproofing liquid, a breast forming material and a lubricant, as well as in the construction field.
상기에서 실리콘 등의 실란트는 액상 또는 페이스트(paste) 상태를 가지며 공기에 노출시 경화되므로 카트리지(cartridge) 내에 밀폐되게 실란트용 카트리지에 내장된다. 카트리지 내에 내장된 상태에서 장기간 동안 경화되지 않도록 하는 것이 중요하다. 그러므로, 내장된 실란트가 외부 공기 중의 습기와 접촉되는 것을 차단하기 위해 카트리지의 기밀성을 향상시키는 것이 매우 중요하다.The sealant such as silicone has a liquid or paste state and is hardened when exposed to air, so that the sealant, such as silicone, is embedded in the sealant cartridge to be sealed in the cartridge. It is important not to cure for a long period of time embedded in the cartridge. Therefore, it is very important to improve the airtightness of the cartridge to prevent the built-in sealant from coming into contact with moisture in the outside air.
기밀성을 향상시키기 위한 실란트용 카트리지가 일본 특개소 60－68272호에 개시되어 있다. 종래 기술에 따른 실란트용 카트리지는 실란트가 내장된 본체와, 본체의 일측 끝단에 설치되어 본체에 내장된 실란트를 외부로 토출하는 노즐부와, 본체의 타측 내부에 삽입되어 가해지는 압력에 의해 일측으로 이동하면서 내장된 실런트를 본체의 외부로 토출하는 플런저(plunger)와, 본체 타측 내부 표면의 플런저와 접촉되는 부분 또는 플런저의 외측표면에 도포된 밀봉 도막으로 형성된다.A sealant cartridge for improving airtightness is disclosed in Japanese Patent Laid-Open No. 60-68272. The sealant cartridge according to the prior art has a main body in which a sealant is embedded, a nozzle part installed at one end of the main body to discharge the sealant embedded in the main body to the outside, and a pressure applied to the other side of the main body to be applied to one side. A plunger for discharging the built-in sealant to the outside of the main body while moving, and a sealing coating film applied to a portion in contact with the plunger of the other inner surface of the main body or the outer surface of the plunger.
상기에서 본체, 플런저 및 토출부 등이 폴리에틸렌 등의 합성수지로 형성된다.In the above, the main body, the plunger, the discharge part, and the like are formed of synthetic resin such as polyethylene.
상술한 구성의 실란트용 카트리지는 노즐을 개봉한 상태에서 압력을 가하여 플런저를 본체의 타측 방향으로 이동시키는 것에 의해 본체에 내장된 실런트를 본체의 외부로 토출한다. 상기에서 밀봉 도막은 본체의 내부 표면과 플런저의 외부 표면 사이의 공간을 채워 외부 공기가 본체 내부로 유입되는 것을 방지하여 내장된 실런트가 경화되지 않도록 한다. The sealant cartridge of the above-described configuration discharges the sealant built into the main body to the outside of the main body by moving the plunger in the other direction of the main body by applying pressure while the nozzle is opened. In the above, the sealing coating fills the space between the inner surface of the body and the outer surface of the plunger to prevent external air from flowing into the body, thereby preventing the embedded sealant from curing.
그러나, 종래 기술에 따른 실란트용 카트리지는 본체, 플런저 및 토출부 등의 기밀성이 부족하여 습기가 내부로 침투되는 것을 방지하지 못하여 보관시 내부의 실리콘 등의 실란트가 경화되는 문제점이 있었다.However, the sealant cartridge according to the prior art has a problem in that the sealant such as silicone inside the sealant is hardened at the time of storage due to insufficient airtightness of the main body, the plunger and the discharge portion, and preventing moisture from penetrating therein.
본 발명의 목적은 상기한 종래 문제점을 해결하기 위하여 발명된 것으로서, 실란트가 경화되는 문제점을 해결하여 실란트를 장기간 보관하기 위해, 본체와 플란저 사이의 기밀성을 높여서 실란트에 습기가 침투를 막는데 있다.An object of the present invention is to invent the above-mentioned conventional problems, to solve the problem that the sealant is cured to increase the airtightness between the main body and the plunger in order to store the sealant for a long time to prevent moisture from penetrating the sealant. .
상기의 목적을 달성하기 위한 본 발명의 실란트용 카트리지는 타측이 개방되며 실란트가 내장되는 본체 및 본체의 타측 내부 표면에 접촉되는 측면부와, 측면부에 곡면으로 연접되는 커버부를 포함한다. The sealant cartridge of the present invention for achieving the above object includes a main body in which the other side is opened and the sealant is built, and a side part in contact with the other inner surface of the main body, and a cover part connected to the side part by curved surfaces.
또한, 본 발명은 커버부의 상단부에 기체가 밀봉된 완충부를 더 구비할 수 있다.In addition, the present invention may further include a buffer in which a gas is sealed at the upper end of the cover part.
또한, 본 발명의 완충부는 연성 소재일 수 있다.In addition, the buffer portion of the present invention may be a soft material.
또한, 본 발명의 측면부 또는 커버부는 탄성 소재로 구성될 수 있다.In addition, the side portion or the cover portion of the present invention may be composed of an elastic material.
또한, 본 발명의 측면부는 나사산과 나사골로 구성된 나사가 형성되어 있으며 상기 나사산이 탄성 소재로 이루어질 수 있다.In addition, the side portion of the present invention is formed with a screw consisting of a screw thread and screw bone, the screw thread may be made of an elastic material.
또한, 본 발명은 나사골에 흡습제가 충진될 수 있다.In addition, the present invention may be filled with a hygroscopic agent in the screw bone.
본 발명에 따른 실란트용 카트리지는 플런저에 의해 습기 등이 본체 내부로 침투되어 실란트가 경화되는 것을 방지할 수 있는 이점이 있다.The sealant cartridge according to the present invention has an advantage of preventing moisture or the like from being penetrated into the main body by the plunger and preventing the sealant from curing.

이하, 첨부한 도면을 참조하여 본 발명을 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.
도1은 본 발명의 일 실시 예에 따른 실란트용 카트리지의 단면도이고, 도2는 본 발명의 일 실시 예에 따른 실란트용 카트리지의 분해도, 도3은 본 발명의 일 실시 예에 따른 실란트용 카트리지의 플런저 단면도, 도4는 본 발명의 다른 실시 예에 따른 실란트용 카트리지의 플런저 단면도이다.1 is a cross-sectional view of a sealant cartridge according to an embodiment of the present invention, Figure 2 is an exploded view of a sealant cartridge according to an embodiment of the present invention, Figure 3 is a sealant cartridge according to an embodiment of the present invention Plunger cross section, Figure 4 is a plunger cross section of a sealant cartridge according to another embodiment of the present invention.
본 발명의 일 실시 예에 따른 실란트용 카트리지는 본체(11), 노즐부(12), 토출보조부(13), 플런저(21), 측면부(22), 커버부(23), 완충부(24), 나사산(25) 및 나사골(26)을 포함한다.Sealant cartridge according to an embodiment of the present invention is the main body 11, the nozzle portion 12, the discharge auxiliary portion 13, the plunger 21, the side portion 22, the cover portion 23, the buffer portion 24 , Thread 25 and threaded bone 26.
상기 본체(11)에는 실란트가 내장되고 개방된 방향에는 플런저(21)가 위치하게 된다. 플런저(21)가 노즐부(12) 방향으로 이동하면 플런저(21)는 내장된 실란트에 힘을 가하게 되고 실란트는 노즐부(12)에서 토출된다. 노즐부(12)에서 토출된 실란트는 토출보조부(13)에 투입되어 사용자가 원하는 굵기로 사용할 수 있게 보조해준다.The sealant is built in the main body 11 and the plunger 21 is positioned in the open direction. When the plunger 21 moves in the direction of the nozzle part 12, the plunger 21 exerts a force on the built-in sealant and the sealant is discharged from the nozzle part 12. The sealant discharged from the nozzle unit 12 is introduced into the discharge assistant 13 to assist the user in using the desired thickness.
상기에서 본체(11)은 실란트가 내장되는 것으로 타측이 개방되는 원통형으로 형성된다. 상기에서 실란트(11)는 본체 내에 액상 또는 페이스트 상태로 내장되어 피접착제를 접착시키는 것으로 공기와 접촉되거나 햇빛에 노출되면 경화된다.The main body 11 is formed in a cylindrical shape in which the other side is opened as the sealant is embedded. In the above-described sealant 11 is embedded in the liquid state or paste in the body to adhere the adhesive to be cured when contacted with air or exposed to sunlight.
상기에서 플런저(21)는 타측 내부에 유동되게 설치된다. 상기에서 플런저(21)은 외측면의 적어도 일부분이 본체(11)의 내부면에 접촉되어 사용자가 외부에서 가하는 압력에 의해 본체(11)의 내부에서 일측 방향으로 이동한다. 이에 의해, 플런저(21)는 본체(11)에 내장된 실란트가 사용자에 의도에 맞게 내부에서 이동할 수 있게 한다.The plunger 21 is installed to flow inside the other side. In the plunger 21, at least a portion of the outer surface is in contact with the inner surface of the main body 11 and moves in one direction from the inside of the main body 11 by a pressure applied by the user from the outside. As a result, the plunger 21 allows the sealant embedded in the main body 11 to move inside the user intentionally.
측면부(22)는 본체의 타측 내부와 접촉하며 기밀성을 유지하여 실란트와 외부 환경이 교통이 없도록 한다. 측면부(22)는 사용자가 사용하지 않는 상태에서는 실란트가 외부환경과 교류하지 않도록 기밀성을 최대한 보유하고 있어야 되지만, 사용자가 사용시에는 플런저(21)가 유동될 수 있게 본체(11)의 개방된 타측 방향에서 힘을 가할시에는 플런저와 본체 사이에 플런저가 충분히 유동할 수 있는 정도의 공간이 생겨야 한다. 플런저의 유동이 쉽게 되지 않을 시에 사용자가 이용할 때 많은 힘을 요하게 된다.The side portion 22 is in contact with the other inside of the main body and maintains airtight so that the sealant and the external environment are free from traffic. The side portion 22 should have the maximum airtightness so that the sealant does not interact with the external environment when the user is not in use, but when the user uses the other side of the main body 11 in the open direction so that the plunger 21 can flow. When exerting force at, the space between the plunger and the body should be sufficient to allow sufficient flow of the plunger. When the plunger does not flow easily, it requires a lot of power when used by the user.
커버부(23)는 실란트가 주는 힘에 대해 견딜 수 있는 내구성이 있어야 한다. 상기 실란트는 온도 등의 외부 환경에 부피가 변화한다. 외부 온도가 높아질 경우 실란트의 부피는 팽창하기에 커버부(23)는 실란트의 부피 팽창에 따른 압력을 흡수할 수 있어야 한다. 사용자가 사용시에는 커버부(23)에 전해지는 사용자의 힘에 의해 실란트가 쉽게 나갈 수 있어야 하기에 본체의 개방된 타측 방향에서의 힘에 대해 실란트에 용이하게 적용되어 실란트가 유동할 수 있도록 한다. Cover portion 23 should be durable to withstand the force given by the sealant. The sealant changes in volume in an external environment such as temperature. When the external temperature increases, the volume of the sealant expands, so that the cover part 23 should be able to absorb the pressure due to the volume expansion of the sealant. When the user is in use, the sealant should be easily exited by the user's force transmitted to the cover 23 so that the sealant can be easily applied to the sealant against the force in the other open direction of the main body.
상기 측면부(22)와 상기 커버부(23)는 PP, PS, 6N, MC, PC, PA 등과 같이 탄성계수가 높은 물질을 사용한다.The side portion 22 and the cover portion 23 uses a material having a high modulus of elasticity, such as PP, PS, 6N, MC, PC, PA, and the like.
완충부(24)는 상기 실란트의 부피 팽창에 따른 압력을 흡수 또는 완충할 수 있어야한다. 상기 완충부는 실란트가 전달하는 힘에 대해선 흡수 또는 완충함과 동시에 실란트에 전달하는 힘에 대해선 용이하게 전달 할 수 있어야 한다. 본 발명은 커버부(23) 위에 완충부(24)를 형성하여 실란트가 전달하는 힘에 대해선 흡수 또는 완충 할 수 있다. 상기 완충부(24)는 HD-PE, PP, PUR, UHMW-PE 등과 같이 신장률이 높은 물질을 사용한다.The buffer 24 should be able to absorb or buffer the pressure due to the volume expansion of the sealant. The shock absorbing portion must be able to absorb or buffer the force transmitted by the sealant and to easily transmit the force transmitted to the sealant. In the present invention, the buffer unit 24 may be formed on the cover unit 23 to absorb or cushion the force transmitted by the sealant. The buffer part 24 uses a material having high elongation such as HD-PE, PP, PUR, UHMW-PE, or the like.
나사산(25)은 측면부(22)에 위치하고 본체 타측 내부와 플런저의 기밀성을 높인다. 나사산(25) 부분이 본체 타측 내부와 접촉하여 실란트와 본체(11) 외부가 접촉하는 것을 막아준다.The thread 25 is located on the side part 22 and improves the airtightness of the inside of the main body and the plunger. The thread 25 portion is in contact with the other side of the main body to prevent the sealant from contacting the outside of the main body 11.
