본 발명의 첨부도면을 참조하여 본 발명의 구성과 작용에 대한 바람직한 일실시예를 상세히 설명하면 다음과 같다.Referring to the accompanying drawings of the present invention will be described in detail a preferred embodiment of the configuration and operation of the present invention.
도 1은 본 발명의 팽윤용매를 이용한 수축튜브의 제조공정을 나타내는 도면으로서, 먼저 변성 폴리에스터(Modified polyester)로 결정성 폴리에스터계 수지인 PET(Poly ethylene trrephtalate)와 PBT(Poly buthylene terephtalate)와 비결정성의 고무특성을 갖는 성분을 결합시킨 공중합체(copolymer)를 사용하여 원하는 크기의 튜브를 압출 또는 사출하여 제조 튜브(1)를 제작한다. 상기 제조 튜브(1)를 제작하는 공정에서 제조된 제조 튜브(1)는 팽윤 용매인 클로로포름(Chloroform)(CHCl3) 또는 혼합제조한 클로로포름에 10분이상 담구어 팽윤 튜브(2)를 제조하게 되는데, 상기와 같이 팽윤 튜브(2)는 팽윤 튜브 제조공정(3)에서 제조된다. 즉, 상기 팽윤 용매인 클로로포름 또는 혼합제조한 클로로포름의 용매속에 제조 튜브(1)를 담구어 팽윤 튜브(2)를 제조하게 된다.1 is a view showing the manufacturing process of the shrink tube using the swelling solvent of the present invention, first modified polyethylene (Modified polyester) of crystalline polyester resin PET (Polyethylene trrephtalate) and PBT (Poly buthylene terephtalate) and The production tube 1 is manufactured by extruding or injecting a tube of a desired size using a copolymer in which a component having amorphous rubber properties is combined. The production tube (1) manufactured in the process of manufacturing the production tube (1) is to swell the swelling tube (2) by immersing in chloroform (CHCl 3 ) or chloroform of mixed swelling for 10 minutes or more As described above, the swelling tube 2 is manufactured in the swelling tube manufacturing process 3. That is, the swelling tube 2 is manufactured by immersing the production tube 1 in a solvent of chloroform, which is the swelling solvent, or a mixed chloroform.
상기 설명과 같이, 변성 폴리에스터(Modified polyester)는 "폴리에스터 공중합체"라고도 하는데, 상기 폴리에스터에 대한 일반적인 특징을 설명하면 다음과 같다.As described above, the modified polyester (Modified polyester) is also referred to as a "polyester copolymer", the general characteristics of the polyester will be described as follows.
일반적인 PET(Poly ethylene trrephtalate)와 PBT(Poly buthylene terephtalate)는 결정성을 갖는 열가소성 폴리머로 딱딱한 특성을 가지며, 상기 PET와 PBT는 클로로포름 용매에 잘녹지 않고 부풀림(swelling) 현상도 없다.In general, polyethylene ethylene trrephtalate (PET) and poly buthylene terephtalate (PBT) are crystalline thermoplastic polymers, which have hard properties. The PET and PBT are not soluble in chloroform solvents and do not have swelling.
따라서, 여기에 부드러운 특성을 갖는 소프트 세그먼트(soft segment)를 붙여 중합시킨 폴리머를 변성 폴리에스터(Modified polyester) 또는 폴리에스터 공중합체(polyester elastomer)라 한다.Therefore, the polymer polymerized by attaching a soft segment having soft properties to the polymer is referred to as a modified polyester or a polyester elastomer.
상기 PET와 PBT 공중합체는 블록 타입 공중합체로 다음과 같은 구조를 갖는다.The PET and PBT copolymers are block type copolymers and have the following structure.
상기 변성 PET(PBT)로 제조된 제조튜브(1)를 용매에 담구면 클로로포름의 용매분자가 변성 PET(PBT)인 제조 튜브(1)의 분자사이로 끼어 들어가게 되고 부풀음(swelling) 현상이 나타나 팽윤 튜브(2)가 제조되며, 이때 상기 제조 튜브(1)는 용매에 잘 녹지 않는 성질을 갖는다.When the production tube 1 made of modified PET (PBT) is immersed in a solvent, solvent molecules of chloroform are sandwiched between molecules of the production tube 1 of modified PET (PBT), and a swelling phenomenon appears. (2) is produced, wherein the production tube (1) has a property of being poorly soluble in a solvent.
상기 팽윤 튜브(2)를 용매에서 꺼내면 용매의 특징상 상온에서 용매의 휘발성이 크므로 시간이 지나면 모두 용매가 휘발하여 원래의 상태로 돌아오게 된다.(상기 용매를 날리는 공정은 일반적으로 후드(hood) 같은 안전장치 내에서 실행한다)When the swelling tube 2 is taken out of the solvent, the solvent has a high volatility at room temperature due to the characteristics of the solvent, so that the solvent volatilizes and returns to its original state over time. (The process of blowing the solvent is generally a hood. Execute in the same safety device)
상기 팽윤튜브 제조공정(3)에서 제조된 팽윤 튜브(2)는 공기를 주입한 포장재(6)를 사용하여 포장하는 포장 공정(4)을 진행한다. 상기 포장 공정(4)에서 사용되는 포장재(6)는 클로로포름에 대한 용해성이 없어야 한다.The swelling tube 2 manufactured in the swelling tube manufacturing process 3 is subjected to the packaging process 4 for packaging using the packaging material 6 infused with air. The packaging material 6 used in the packaging process 4 should not be soluble in chloroform.
상기 포장 공정(4)을 통해 포장된 팽윤 튜브(2)는 사용시 포장을 제거하고 원하는 물체부위에 끼워놓은 후 상온에서 3시간 이상 방치하거나 낮은 열을 가하여 용매를 기화시키면 원래의 크기로 돌아오게되는 수축공정(5)으로 구성된다. 상기 팽윤 튜브(2)의 수축공정(5)에서 일어나는 수축현상을 일으키기위한 방치하는 시간과 가하는 열의 양은 제조 튜브(1)의 재질과 크기에 따라 변할수 있음은 당연하다.The swelling tube (2) packaged through the packaging process (4) is removed from the packaging during use and inserted into the desired object portion, and left at room temperature for at least 3 hours or by applying low heat to vaporize the solvent to return to its original size It consists of a shrinkage process (5). Of course, the amount of heat to be left and the amount of heat applied to cause the shrinkage phenomenon occurring in the shrinking process (5) of the swelling tube (2) may vary depending on the material and size of the production tube (1).
상기 제조 튜브 제조공정, 팽윤튜브 제조공정(3), 포장 공정(4) 및 수축공정(5)을 통하여 용매팽윤을 이용한 수축튜브가 제조에서 제품의 사용까지 끝나게 되는데, 변성 폴리에스터는 강도 내충격성, 경도 등의 기계적 특성뿐 아니라 전기적 특성도 좋은 반면 녹는 온도가 200°C - 250°C 사이로 다른 열수축 수지에 비해 공정 온도가 높기 때문에 열수축 튜브의 제조시 가공뿐 아니라 가교, 팽창 공정에도 어려움이 있어 열수축 튜브로는 사용하지 않지만, PVC(Poly vinylchloride)용매 수축튜브보다 열적, 기계적 특성이 우수하다는 장점으로 인해 수축튜브로 사용하는 것이다.Through the manufacturing tube manufacturing process, swelling tube manufacturing process (3), packaging process (4) and shrinkage process (5), the shrink tube using the solvent swelling is finished from the production to the use of the product, the modified polyester is impact resistance In addition to the mechanical properties such as hardness and hardness, the electrical properties are good, while the melting temperature is between 200 ° C-250 ° C, so the process temperature is higher than that of other heat shrink resins. Although it is not used as a heat shrink tube, it is used as a shrink tube because of its superior thermal and mechanical properties than polyvinyl chloride (PVC) solvent shrink tubes.
상기 변성 폴리에스터는 통상 사용하는 열수축 튜브 제품의 용도와 동일하며, 전선 연결부위의 절연 및 보호, 기타 파이프 유사제품의 외관보호 등에 적용할 수 있고, 특히 상기 제품은 화학적, 기계적 특성이 다른 폴리머 재질보다 우수하여 내열성 및 경도가 우수하므로 특수용도로 사용하게 된다.The modified polyester is the same as a commonly used heat shrink tubing product, and can be applied to insulation and protection of wire connection parts and external appearance protection of similar pipe products, and in particular, the product is made of a polymer material having different chemical and mechanical properties. It is superior to heat resistance and hardness, so it is used for special purpose.
상기 변성 폴리에스터와 일반적인 폴리올레핀의 특징을 살펴보면 비교예와 같다.Looking at the characteristics of the modified polyester and the general polyolefin is the same as the comparative example.
〈 비교예 〉<Comparative Example>
상기 팽윤 용매로는 클로로포름 또는 클로로포름(Chloroform), 아세톤(Aceton), 메틸 알코올(Methyl alcohol), 에틸 알코올(Ethyl alcohol) 및 테트라 하이드로프란(Tetra hydrofurane)과 같은 용제를 0 - 15%(v/v)로 혼합시킨 혼합용액을 사용할 수도 있다. 상기 용매의 혼합비율은 폴리머(polymer)의 종류에 따라 다르나 통상 클로로포름이 가장 효과적이라 할 수 있다.The swelling solvent is a solvent such as chloroform or chloroform (Chloroform), acetone (Aceton), methyl alcohol (Methyl alcohol), ethyl alcohol (Ethyl alcohol) and tetra hydrofurane (v / v) The mixed solution mixed with) can also be used. The mixing ratio of the solvent varies depending on the type of polymer, but chloroform is usually the most effective.
전술한 구성과 작용에 의한 본 발명의 효과를 설명하면 다음과 같다.Referring to the effects of the present invention by the above-described configuration and operation are as follows.
열수축 튜브의 경우는 사용할 때 열수축 튜브의 팽창시의 온도로 사용하여야하는 반면에, 본 발명에 의한 용매팽윤을 이용한 수축튜브는 제조튜브 제조공정에서 제조된 제조튜브를 용매에 담군후 팽창된 팽윤튜브를 꺼내서 공기를 주입시킨 포장지에 밀봉한 후 상온에서 사용하거나 낮은 온도로 가열해 사용할 수 있으므로 제조 및 제품에 대한 사용공정이 간단한 장점이 있고, 또한 제조된 수축 튜브는 열적, 기계적 특성이 우수한 장점이 있다.In the case of the heat shrinkable tube, the shrinkage tube using the solvent swelling according to the present invention should be used as the temperature at the time of expansion of the heat shrinkable tube. The product can be used at room temperature or heated to a low temperature after being sealed by air-packed wrapping paper, and the manufacturing process for the product and the product are simple, and the manufactured shrink tube has excellent thermal and mechanical properties. have.
