Description
본 발명은 젤 상태로 상하수관, 가스관, 각종 전선, 파이프, 문틀 등의 접속부에 밀봉 및 충전 접합하여 충격 흡수, 누수 , 부식 등을 방지할 수 있도록 하는 탄성 고분자 젤에 관련된 것이다. 상기 탄성 고분자 젤은 소정의 높은 온도로 가열되면 수지 공중합체가 용융되기 시작하면서 점도가 낮은 유체로 되고, 그 유체를 실온에 방치하여 다시 냉각시키면 점도가 높은 부분과 낮은 부분 사이에 망상 구조가 형성되면서 젤 형태가 된다.The present invention relates to an elastomeric polymer gel that can be sealed and filled in joints such as water and sewage pipes, gas pipes, various wires, pipes, door frames, and the like to prevent shock absorption, leakage, and corrosion. When the elastomeric gel is heated to a predetermined high temperature, the resin copolymer starts to melt and becomes a fluid having a low viscosity, and when the fluid is left at room temperature and cooled again, a network structure is formed between the high viscosity portion and the low portion. It becomes gel form.
상기와 같은 특징을 갖는 고분자 젤은 일반적으로 상하수관이나 전선, 파이프 등의 접촉부에 충전 접합하여 충격흡수나 누수, 부식 등을 방지하기 위하여 사용된다.The polymer gel having the above characteristics is generally used for filling and contacting contact parts such as water and sewage pipes, electric wires, and pipes to prevent shock absorption, leakage, and corrosion.
더 구체적으로 설명하면 상기 탄성 고분자 젤은 미네랄 및 실리콘 오일 등으로 된 분산매에 소정의 젤화제를 넣어 용해시킨 후 그 젤 상태의 용액에 SEBS(Styrene Ethyene Butylene styrene) 블록공중합체로 된 수지를 넣어 가열 교반하고, 그 젤이 상기 수지 내에 침투하여 결합하도록 제조한다. 상기 종래의 탄성고분자 젤의 제조시에는 탄성 고분자 젤의 특성 즉, 응력, 탄성력 내식성, 인장력 등을 향상시키기 위하여 점착제, 산화방지제, 난연제, 계면활성제, 기포방지제 등을 첨가한다.More specifically, the elastic polymer gel is dissolved by putting a predetermined gelling agent in a dispersion medium made of mineral and silicone oil, and then heated with a resin of SEBS (Styrene Ethyene Butylene styrene) block copolymer in the gel solution. Stir and prepare the gel to penetrate into the resin and bind. In the preparation of the conventional elastic polymer gel, an adhesive, an antioxidant, a flame retardant, a surfactant, an anti-foaming agent, etc. are added to improve the characteristics of the elastic polymer gel, that is, stress, elasticity corrosion resistance, and tensile strength.
그러나, 상기와 같은 과정에 의하여 제조되는 종래의 고분자 젤은 상기 고분자 수지 내에 분산매 즉, 오일이 침투한 상태로 결합하여 신축성과 탄성을 주는 오일과 강도를 유지하여 주는 고분자 수지간의 결합력이 약한 문제점이 있다.However, the conventional polymer gel prepared by the above process has a weak bonding strength between the polymer resin that maintains the strength and the elasticity and elasticity by combining the dispersion medium, that is, the oil penetrated into the polymer resin in the state that the oil penetrated. have.
상기 고분자 수지와 오일간의 결합력의 약하면 상하수도관 등에 시공한 후 시간이 경과함에 따라 고분자 수지 내에 침투된 분산매 오일과의 결합력이 쉽게 깨져 고분자 수지와 오일간에 상분리가 일어난다.When the binding force between the polymer resin and the oil is weak, after the construction of the water and sewage pipe, the bonding force with the dispersion medium oil penetrated into the polymer resin is easily broken, and phase separation occurs between the polymer resin and the oil.
상기 탄성 고분자 젤의 상분리는 그 젤의 파괴 강도나 신장률, 크리이프, 균일성 등에 악영향을 미치고, 시간이 지남에 따라 품질이 현저히 열화된다Phase separation of the elastomeric gel adversely affects the breaking strength, elongation, creep, and uniformity of the gel, and the quality deteriorates significantly with time.
따라서, 상기와 같은 종래의 탄성 고분자 물질은 초기에는 미네날 및 시리콘 오일로 가소화 되어 있지만 인장강도나 신율 등의 기계적 성질이 낮고, 시공 후 시간이 경과함에 따라 파괴력, 신장력, 크리이프, 균열 및 인열특성이 현저히 떨어지는 문제점이 있다.Therefore, the conventional elastic polymer materials as described above are initially plasticized with mineral and silicone oil, but have low mechanical properties such as tensile strength and elongation, and have breakage, elongation, creep, cracking and tearing with time after construction. There is a problem that the characteristics are significantly reduced.
또, 각종의 다른 배합물질과 배합되었을 때 젤의 비상용성으로 인하여 배합물질이 불균일하여 지고, 접착력이 약하여 파이프 등의 접속부에서 쉽게 떨어지는 문제점이 있다.In addition, when blended with various other compounding materials, the compounding material becomes non-uniform due to the incompatibility of the gel, and there is a problem in that the adhesive strength is weak and easily falls from the connection part such as pipe.
또, 철, 플라스틱, 자기류 등의 각종 재질로 만들어진 접속부에 사용할 경우 그 접속부의 접합이 어렵고, 접속부로부터 고분자 젤을 떼어낼 때도 기계적인 성질이 열악하여 고분자 젤 충전물 자체가 손상되는 문제점이 있다.In addition, when used in connection parts made of various materials such as iron, plastic, magnetics, it is difficult to join the connection, and even when removing the polymer gel from the connection, the mechanical properties are poor, there is a problem that the polymer gel filler itself is damaged.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로 미네랄 및 실리콘 오일과 고분자 수지가 물리적인 네트워크 중합반응에 의하여 결합하도록 하여 상분리가 일어나는 것을 방지함으로서 탄성 고분자 젤의 기계적인 성질을 향상시키는 것을 목적으로 한다.An object of the present invention is to improve the mechanical properties of the elastomeric gel by preventing the phase separation by allowing the mineral, silicone oil and polymer resin to be bonded by a physical network polymerization reaction to solve the above problems. It is done.
본 발명의 또 다른 목적은 상기 미네랄 및 실리콘 오일과 고분자 수지간의 상분리가 방지되는 젤을 제공함으로서 철, 플라스틱, 자기류 등의 각종 재질로 만들어진 접속부에 사용할 경우 그 접속부에 접합(결합)이 잘되고, 시공 후 시간이 경과하더라도 젤의 파괴력, 신장력, 크리이프, 균열 및 인열 특성이 변하지 않도록 하는데 있다.Still another object of the present invention is to provide a gel that prevents phase separation between the mineral and silicone oil and the polymer resin, and when used in a connection part made of various materials such as iron, plastic, magnetics, etc. Even after time passes, the gel's breaking, stretching, creep, cracking and tearing properties do not change.
상기 목적 달성을 위하여 본 발명은 먼저 분산매로 작용하는 미네날 오일 및 실리콘 오일에 틱소겔(Tixogel) 또는 테트라에틸암모늄 브로마이드(tetraethylammonoium bromid)로 된 겔화제를 용융시켜 오일용액을 만드는 공정,In order to achieve the above object, the present invention first melts a gelling agent made of thixogel or tetraethylammonoium bromid in a mineral oil and a silicone oil which act as a dispersion medium, thereby making an oil solution.
이어서, 상기와 같이 제조된 오일 용액에 폴리이소프렌(polyisoprene)과 SEBS 블록공중합체로 수지를 혼합하는 공정,Next, a process of mixing the resin with a polyisoprene and SEBS block copolymer in the oil solution prepared as described above,
상기 혼합물을 150℃에서 250℃까지 가열하여 용융시키는 공정,Melting the mixture by heating from 150 ° C. to 250 ° C.,

상기 실시예 1내지 5에 의한 실험방법에서는 먼저, 질소 분위기 하에서 반응기에 분산매인 미네랄 오일과 실리콘 오일을 넣고, 젤화제를 넣어 용해시킨다. 상기 젤화제는 미네랄 오일과 실리콘 오일에 대하여 SEBS 블록공중합체 및 폴리이소프렌 수지의 분산, 확산, 팽창을 균일하고 신속하게 이루어지도록 작용한다. 젤화제가 용해되어 있는 오일에 폴리이소프렌, SEBS 블록공중합체, 난연제, 점착제, 산화방지제, 계면활성제, 기포제거제를 소정량 혼합한다.In the experimental method according to Examples 1 to 5, first, the mineral oil and the silicone oil, which are dispersion mediums, are added to the reactor under a nitrogen atmosphere, and then the gelling agent is added to dissolve. The gelling agent acts to uniformly and rapidly disperse, diffuse, and expand SEBS block copolymer and polyisoprene resin with respect to mineral oil and silicone oil. A predetermined amount of polyisoprene, SEBS block copolymer, flame retardant, pressure-sensitive adhesive, antioxidant, surfactant, and defoamer is mixed with oil in which gelling agent is dissolved.
이어서, 상기 혼합물을 150∼200℃ 사이에서 3∼6시간 동안 교반하면서 적절한 점도가 되도록 반응시킨 후 상온에 방치하여 제조한다.Subsequently, the mixture is reacted to an appropriate viscosity while stirring for 3 to 6 hours between 150 to 200 ° C, and then left to stand at room temperature.
상기 가열 교반 과정에서 SBS 블록공중합체와 폴리이소프렌 수지에 미네랄 오일과 실리콘 오일이 다가가면 그 오일과 혼합되면서 가소화 과정이 일어나고, 그 오일에 의하여 SBS 블록 공중합체와 폴리이소프렌의 확산이나 팽창이 일어난다. 상기 팽창과 함께 미네랄 오일과 실리콘 오일로 확산이 일어나고 동시에 중합개시제의 작용에 의하여 실리콘 오일과 중합반응을 일으켜 팽창된 탄성을 지닌 고분자 젤이 형성된다.When the mineral oil and the silicone oil approach the SBS block copolymer and the polyisoprene resin in the heating and stirring process, the oil is mixed with the oil to cause plasticization, and the oil diffuses or expands the SBS block copolymer and the polyisoprene. . With the expansion, diffusion occurs into the mineral oil and the silicone oil, and at the same time, a polymerization reaction with the silicone oil is formed by the action of the polymerization initiator, thereby forming a polymer gel having expanded elasticity.

본 발명의 실시예에서 사용한 수지는 라텍스의 탄성을 갖는 폴리이소프렌과 SEBS 블록공중합체이며, SEBS의 스틸렌 블록과 에틸렌 블록의 성분비율과 폴리이소프렌의 조합에 따라 물성이 달라진다. 이때 SEBS 블록공중합체는 평균분자량의 폭이 좁은 것보다는 넓은 것이 서로 잘 혼합되고 폴리이소프렌을 첨가함으로서 최소한의 용적으로 탄성 고분자 젤을 균일하게 충전 할 수 있도록 하였다.The resin used in the embodiment of the present invention is a polyisoprene and SEBS block copolymer having elasticity of latex, and the physical properties vary according to the combination of polyisoprene and the component ratio of the styrene block and the ethylene block of SEBS. At this time, the SEBS block copolymer is a wider than the narrow average molecular weight is well mixed with each other and by adding polyisoprene to uniformly fill the elastomeric gel with a minimum volume.
본 발명의 실험 결과 분산매 오일과 수지의 비율은 각각 80∼85w%, 15∼20w%로 구성하고, 상기 분산매 오일 중 미네랄 오일과 실리콘 오일의 비율은 각각 80wt%와 20wt%의 비율로 구성하고, 상기 수지 중 폴리이소프렌과 SEBS 블록공중합체의 비율은 각각 30wt%와 70wt%의 비율로 구성하였을 때 이상적이 결과가 얻어졌고, 특히, 상기 SEBS 수지는 스틸렌블록이 29∼33w%, 에틸렌블록이 67∼71w%이고, 중량평균 분자량이 50,000∼240,000의 범위에 있을 때 가장 이상적이었다.As a result of the experiment of the present invention, the ratio of the dispersion medium oil and the resin is 80-85w% and 15-20w%, respectively, and the ratio of the mineral oil and the silicone oil in the dispersion medium oil is 80wt% and 20wt%, respectively. When the ratio of polyisoprene and SEBS block copolymer in the resin was composed of 30wt% and 70wt%, an ideal result was obtained. In particular, the SEBS resin is 29-33w% styrene block and 67% ethylene block. It was -71w%, and it was most ideal when the weight average molecular weight was in the range of 50,000-240,000.
상기와 같이 구성되는 본 발명의 탄성 고분자 젤은 상하수도관 및 전선 등의 매몰 케이스에 접합제로 충진하여 사용할 수 있다. 상기 탄성 고분자 젤은 폴리이소프렌과 SEBS 블록공중합체를 혼합하여 사용함으로서 그 젤의 응력과 탄성력을 크게하는 효과를 얻을 수 있다.The elastic polymer gel of the present invention configured as described above can be used by filling in a buried case, such as water and sewage pipes and wires as a binder. The elastic polymer gel may be obtained by mixing polyisoprene and SEBS block copolymer to increase the stress and elastic force of the gel.
또, 분산매로 사용하는 반응오일은 미네랄 오일과 실리콘 오일을 혼합하여 사용함으로서 온도를 증가시켜 수지와 교반하는 과정에서 반응 초기에는 두 오일이 분산매로 작용하다가 점차 수지에 오일이 확산되고 온도가 증가함에 따라 수지에 분산된 오일 중 실리콘 오일은 수지와 상호 물리적 네트워크 형태의 중합반응을 일으켜 결합력이 커지게 된다. 따라서, 종래의 탄성 고분자 젤이 가지고 있던 문제점 즉, 오일이 수지에 침투된 형태의 결합구조에 있어서, 시간이 지남에 따라 오일과 수지의 상분리가 일어나는 것을 근본적으로 해결하는 효과를 얻을 수 있다.In addition, the reaction oil used as the dispersion medium is a mixture of mineral oil and silicone oil to increase the temperature, the two oils act as a dispersion medium at the beginning of the reaction in the process of stirring with the resin, the oil gradually diffuses into the resin and the temperature increases. Accordingly, silicone oil in the oil dispersed in the resin causes a polymerization reaction in the form of a physical network with the resin, thereby increasing the bonding strength. Therefore, the problem that the conventional elastic polymer gel has, that is, in the bonding structure in which the oil penetrates the resin, it is possible to obtain the effect of fundamentally solving the phase separation of the oil and the resin over time.
또, 시간이 지남에 따라 오일과 수지의 상분리가 일어나지 않음으로 외부로부터 반복되는 탄성과 응력에 대응할 수 있는 물성을 얻을 수 있고, 재사용이 가능한 장점이 있다.In addition, as the phase separation of the oil and the resin does not occur over time, it is possible to obtain physical properties that can cope with repeated elasticity and stress from the outside, and reusable.
