Description
본 발명은 니트릴계 고무에 부틸계 고무를 혼합하고 여기에 침전 실리카 등을 혼합함으로써 슬립저항성 및 내마모성 등의 물성을 향상시킬 수 있도록 하는, 모노 펌프 고정자용 부틸계 고무 조성물 및 이를 이용하여 제조되는 모노 펌프 고정자에 관한 것이다.The present invention is to improve the properties such as slip resistance and abrasion resistance by mixing butyl rubber with nitrile rubber and mixing precipitated silica therein, and a mono-pump stator butyl rubber composition prepared using the same. It relates to the pump stator.
일반적으로 모노 펌프는 프랑스의 모-노(Rene Moineau)라는 수학박사가 프랑스 공군의 의뢰를 받아 공군기 엔진의 슈퍼 차져(super Charger)를 개발하던 중 액체를 연속적으로 정량이송하는 펌프원리를 발명하였다고 하여 붙여 지게된 펌프로써 모노펌프의 구성요소 중 하나인 고정자는 금속제 외통의 안쪽에 탄성재로 성형시킨 암나사이며, 이 탄성재는 모두 외통에 굳게 접착되어 있어 로타의 격한 밀착 회전에도 나사가 상하지 않고 우수한 자흡력, 정량성, 내구성을 발휘하여야 한다.In general, the monopump is said to have invented the principle of a pump that continuously quantitatively transfers liquid while developing a super charger for an air force engine at the request of the French Air Force by a doctor of mathematics named Rene Moineau of France. As the attached pump, the stator, one of the components of the monopump, is a female screw molded with an elastic material inside the metal outer cylinder, and all of these elastic materials are firmly bonded to the outer cylinder, so the screw is not damaged even when the rotor rotates closely and is excellent. Absorption, quantitative, and durability must be exhibited.
상기 탄성재는 어느 단면도 같은 장원형, 그 사이즈는 단면방향은 로타경과 거의 같고 장원방형은 로타경의 약 2배가 되며, 이 장원형은 고정자의 입구에서 출구로 향해 시계 방향으로 감겨져서 로타의 2배의 피치로 2조의 암나사가 형성되어 있다. 그리고 고정자는 용도에 맞춰 각종 고무제품을 비롯하여 수지나 금속 등으로 제작하고 있다.The elastic material has an oblong shape like a cross section, and its size is approximately the same as the rotor diameter, and the oblong square is approximately twice the rotor diameter, and this oblong shape is wound clockwise from the inlet to the outlet of the stator and is twice as large as the rotor. Two sets of female threads are formed with a pitch. And the stator is made of resin or metal as well as various rubber products according to the purpose.
그리고 상기와 같은 모노 펌프는 추진공동형펌프, 편심스크류펌프, 또는 나선형 로타펌프 등으로 불리고, 점도성이 높은 유동물을 압축 이송하여 연속적으로 배출할 수 있는 장치로서, 화학, 도료, 화장품, 제지펄프, 제당, 요업, 등의 다양한 분야에서 이용되고 있고 사용분야가 점차 확대되고 있다.And the mono pump as described above is called a propelling joint pump, an eccentric screw pump, or a spiral rotor pump, and is a device capable of continuously discharging a fluid with high viscosity by compressing and conveying it. It is used in various fields such as pulp, sugar, ceramics, etc., and the fields of use are gradually expanding.
하지만, 탄성을 가지는 모노 펌프 고정자(stator)를 성형하여 제조할 때, 실제 고정자의 유동로에서 회전되는 회전자와 동일한 형태와 크기의 회전자모델을 이용하여 고정자의 유동로를 형성시키기 때문에, 모노펌프의 사용으로 인하여 고정자의 유동로가 일부 마모된 경우, 모노펌프의 이송압력이 급격하게 저하되는 문제가 발생된다.However, when manufacturing a mono-pump stator having elasticity, the flow path of the stator is formed by using a rotor model of the same shape and size as the rotor rotating in the actual flow path of the stator. When the flow path of the stator is partially worn due to the use of the pump, there is a problem that the transfer pressure of the monopump is rapidly decreased.
또한, 기존의 모노 펌프의 회전자가 고정자 내부에서 회전하여 원료를 이송시킬 경우 회전자와 고무재질인 이송부와 마찰력으로 인해 마찰열이 발생되고 이로인해 장시간 사용 시 고정자가 파손되는 단점이 발생된다.In addition, when the rotor of the conventional mono pump rotates inside the stator and transfers raw materials, frictional heat is generated due to the frictional force between the rotor and the transfer part made of rubber, which leads to a disadvantage that the stator is damaged when used for a long time.
이를 해결하기 위하여 특허문헌 1 및 2 등에서는 고정자의 형태 변형을 통해 이를 해결하고자 하였으나, 실제 상기와 같은 단점을 해소하기 어려운 문제점이 있었다.In order to solve this problem, Patent Documents 1 and 2 attempted to solve this problem by modifying the shape of the stator, but there is a problem in that it is difficult to solve the above disadvantages.
즉, 슬립저항성이나 내마모성을 동시에 만족시켜 고정자에 형성된 공간층에 의해 회전자와 이송부의 마찰력에 의한 열을 흡수시킴으로써 열 발생에 따른 이송부의 손상을 방지 할 수 있는 기술이 절실히 필요한 실정이다.That is, there is a desperate need for a technology capable of preventing damage to the transfer part due to heat generation by simultaneously satisfying slip resistance and abrasion resistance and absorbing heat due to frictional force between the rotor and the transfer part by the space layer formed on the stator.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 니트릴계 고무에 부틸계 고무를 혼합하고, 여기에 침전 실리카(precipitated silica) 등을 혼합하여 모노 펌프 고정자를 제조함으로써, 모노 펌프 고정자의 슬립저항성 및 내마모성 등의 물성을 향상시킬 수 있도록 함을 과제로 한다.The present invention is to solve the above problems, by mixing a nitrile-based rubber with a butyl-based rubber, and mixing precipitated silica thereto to prepare a monopump stator, and thus, the slip resistance of the monopump stator and The task is to be able to improve physical properties such as abrasion resistance.

아울러, 본 발명은 상기와 같은 조성물을 이용하여 제조되는 모노 펌프 고정자를 과제의 다른 해결 수단으로 한다.In addition, the present invention uses a mono pump stator manufactured using the above composition as another solution to the problem.
여기서 상기 고무기재는, NBR(acrylonitrile-butadiene rubber) 40 ~ 50 중량% 및 BR(polybutadiene rubber), SBR(styrene-butadiene rubber) 또는 IIR(Isobutene-isoprene rubber) 50 ~ 60 중량%가 혼합되어 이루어지는 것이 바람직하다.Here, the rubber substrate is made by mixing 40 to 50% by weight of acrylonitrile-butadiene rubber (NBR) and 50 to 60% by weight of polybutadiene rubber (BR), styrene-butadiene rubber (SBR), or isobutene-isoprene rubber (IIR). desirable.
그리고 상기 가교제는 황 또는 퍼옥사이드 가교제를 사용하고, 상기 보강성 충진제는 침전 실리카(precipitated silica)를 사용하는 것이 바람직하다.In addition, the crosslinking agent is preferably a sulfur or peroxide crosslinking agent, and the reinforcing filler is preferably precipitated silica.
본 발명은 니트릴계 고무에 부틸계 고무를 혼합하여 슬립저항성을 향상시킬 뿐만 아니라 침전 실리카 등을 혼합함으로써 내마모성 등의 물성을 향상시킬 수 있는 효과가 있다.The present invention has an effect of improving slip resistance by mixing nitrile-based rubber with butyl-based rubber, as well as improving physical properties such as abrasion resistance by mixing precipitated silica and the like.
본 발명은 슬립저항성이 우수한 모노 펌프 고정자용 부틸계 고무 조성물 및 이를 이용하여 제조되는 모노 펌프 고정자에 관한 것으로서, 본 발명의 기술적 구성을 이해하는데 필요한 부분만이 설명되며 그 이외 부분의 설명은 본 발명의 요지를 흩트리지 않도록 생략될 것이라는 것을 유의하여야 한다.The present invention relates to a butyl-based rubber composition for a mono pump stator having excellent slip resistance and a mono pump stator manufactured using the same, and only parts necessary to understand the technical configuration of the present invention are described, and the description of other parts is the present invention. It should be noted that it will be omitted so as not to distract from the gist of.
이하, 본 발명에 따른 슬립저항성이 우수한 모노 펌프 고정자용 부틸계 고무 조성물 및 이를 이용하여 제조되는 모노 펌프 고정자를 상세히 설명하면 다음과 같다.Hereinafter, a butyl-based rubber composition for a mono pump stator having excellent slip resistance according to the present invention and a mono pump stator manufactured using the same will be described in detail.
본 발명에 따른 슬립저항성이 우수한 모노 펌프 고정자용 부틸계 고무 조성물 및 이를 이용하여 제조되는 모노 펌프 고정자는 고무기재 100 중량부에 대하여, 가교제 0.01 ~ 0.5 중량부, 보강성 충진제 1 ~ 10 중량부, 가교 촉진제 0.01 ~ 0.03 중량부, 금속산화물 2 ~ 4 중량부, 스테아린산 0.5 ~ 2.5 중량부 및 노화방지제 0.3 ~ 1.5 중량부를 포함하여 이루어지는 것을 특징으로 한다.The butyl-based rubber composition for a monopump stator having excellent slip resistance according to the present invention and a monopump stator manufactured using the same are 0.01 to 0.5 parts by weight of a crosslinking agent, 1 to 10 parts by weight of a reinforcing filler, It characterized in that it comprises 0.01 to 0.03 parts by weight of a crosslinking accelerator, 2 to 4 parts by weight of a metal oxide, 0.5 to 2.5 parts by weight of stearic acid, and 0.3 to 1.5 parts by weight of an anti-aging agent.
상기 고무기재는 NBR(acrylonitrile-butadiene rubber) 40 ~ 50 중량% 및 BR(polybutadiene rubber), SBR(styrene-butadiene rubber) 또는 IIR(Isobutene-isoprene rubber) 50 ~ 60 중량%가 혼합되어 이루어진다. 여기서 상기 BR, SBR 또는 IIR의 경우 변성(modified) SBR, 변성 BR 및 변성 IIR 등의 적용이 가능하며, 상기 NBR과의 혼합비가 상기 범위를 벗어날 경우 슬립저항성이 미비해질 우려가 있다.The rubber substrate is made by mixing 40 to 50% by weight of acrylonitrile-butadiene rubber (NBR) and 50 to 60% by weight of polybutadiene rubber (BR), styrene-butadiene rubber (SBR), or isobutene-isoprene rubber (IIR). Here, in the case of BR, SBR, or IIR, modified SBR, modified BR, and modified IIR can be applied, and if the mixing ratio with the NBR is out of the above range, there is a concern that slip resistance may be insufficient.
상기 가교제는 황 또는 디큐밀 퍼옥사이드 등과 같은 퍼옥사이드 가교제의 적용이 가능하며, 그 사용량이 0.01 중량부 미만일 경우 가교가 되지 않아 고정자 성형이 어려울 수 있으며, 0.5 중량부를 초과할 경우 경도가 급격히 높아지고 물성이 저하될 우려가 있다. The crosslinking agent can be applied with a peroxide crosslinking agent such as sulfur or dicumyl peroxide, and if the amount is less than 0.01 parts by weight, crosslinking may not be possible and thus stator molding may be difficult.If it exceeds 0.5 parts by weight, the hardness increases rapidly and physical properties There is a possibility that this may decrease.
상기 보강성 충진제는 고정자의 물성 향상을 목적으로 첨가되는 것으로 침전 실리카(precipitated silica)를 사용한다. 한편, 상기 보강성 충진제의 사용량이 1 중량부 미만일 경우 물성 보강효과가 미비해질 우려가 있으며, 10 중량부를 초과할 경우 점도 증가로 인하여 경도의 급격한 향상 및 흐름성이 저하될 우려가 있다The reinforcing filler is added for the purpose of improving the properties of the stator and uses precipitated silica. On the other hand, if the amount of the reinforcing filler is less than 1 part by weight, the reinforcing effect of physical properties may be insufficient, and if it exceeds 10 parts by weight, there is a risk of a sharp improvement in hardness and a decrease in flowability due to an increase in viscosity.
상기 가교촉진제는 성형시간 단축과 적정 가교구조를 얻기 위한 것으로 트리아릴 시아누레이트(tri-Aryl cyanurate), 테트라메틸티우람 모노설파이드(Tetramethylthiuram monosulfide) 등의 적용이 가능하며, 그 사용량이 0.01 중량부 미만일 경우에는 상기 기능이 제대로 발휘되지 못할 우려가 있으며, 0.03 중량부를 초과할 경우 과도한 가교로 인하여 물성이 저하될 우려가 있다. The crosslinking accelerator is to shorten the molding time and obtain an appropriate crosslinking structure, and can be applied such as tri-Aryl cyanurate, tetramethylthiuram monosulfide, and the like, and the amount used is 0.01 parts by weight. If it is less than, there is a fear that the function may not be properly exhibited, and if it exceeds 0.03 parts by weight, physical properties may be deteriorated due to excessive crosslinking.
상기 금속산화물은 가교 속도 조절과 물성을 향상시키는 역할을 하는 것으로서, 산화아연, 산화마그네슘, 산화칼슘 등의 사용이 가능하며, 그 사용량이 2 중량부 미만일 경우에는 가교 속도가 떨어져 물성이 저하될 우려가 있고, 4 중량부를 초과할 경우에는 가교 속도가 너무 빨라 도리어 물성이 저하될 우려가 있다.The metal oxide plays a role in controlling the crosslinking rate and improving physical properties, and zinc oxide, magnesium oxide, calcium oxide, etc. can be used, and if the amount is less than 2 parts by weight, the crosslinking rate is lowered and the physical properties may be deteriorated. In the case of exceeding 4 parts by weight, the crosslinking speed is too fast, but there is a concern that physical properties may be deteriorated.
상기 스테아린산은 고무 기재에 첨가된 혼합물을 균일하게 분산시키는 역할을 하는 것으로서, 그 사용량이 0.5 중량부 미만일 경우에는 고무 기재에 첨가된 혼합물이 충분히 분산되지 않을 우려가 있고, 2.5 중량부를 초과할 경우에는 그에 따른 효과가 미약하며 과사용에 따른 성형물의 표면에 스테아린산이 용출될 우려가 있다.The stearic acid serves to uniformly disperse the mixture added to the rubber substrate, and if the amount is less than 0.5 parts by weight, there is a possibility that the mixture added to the rubber substrate may not be sufficiently dispersed, and if it exceeds 2.5 parts by weight The resulting effect is weak, and there is a concern that stearic acid may be eluted on the surface of the molded product due to overuse.
상기 노화방지제는 고무의 컴파운드 제조, 이송 및 보관에서 나타나는 물성 저하를 방지하기 위한 역할을 하는 것으로서, N,N'-디페닐-p-페닐렌디아민(N,N'-diphenyl-p- phenylenediamine), 4,4'-비스(알파,알파-디메틸벤질)디-페닐아민(4,4'-Bis(alpha,alpha- dimethylbenzyl)di -phenylamine), 중합 1,2-디하이드로-2,2,4-트리메틸 퀴놀린(polymerized 1,2-dihydro-2,2,4-trimethyl quinoline) 등의 사용이 가능하다. 한편 노화방지제의 사용량이 0.3 중량부 미만일 경우에는 노화방지 효과를 기대하기 어렵고, 1.5 중량부를 초과할 경우에는 노화방지제의 사용량 과다로 고무 컴파운드 등의 표면에 노화방지제가 분출될 우려가 있다.The anti-aging agent serves to prevent the deterioration of physical properties occurring in the manufacture, transport and storage of the rubber compound, and N,N'-diphenyl-p-phenylenediamine (N,N'-diphenyl-p-phenylenediamine) , 4,4'-Bis(alpha,alpha-dimethylbenzyl)di-phenylamine), polymerization 1,2-dihydro-2,2, It is possible to use 4-trimethyl quinoline (polymerized 1,2-dihydro-2,2,4-trimethyl quinoline). On the other hand, if the amount of the anti-aging agent is less than 0.3 parts by weight, it is difficult to expect the anti-aging effect, and if it exceeds 1.5 parts by weight, there is a concern that the anti-aging agent is ejected on the surface of the rubber compound due to the excessive amount of the anti-aging agent.
