쇽업소버의 씰링부재용 고무 조성물{Rubber composition for sealing of shock absorber}Rubber composition for sealing member of shock absorber

본 발명은 쇽업소버의 씰링부재용 고무 조성물에 관한 것으로, 더욱 상세하게는 현가장치에 구비된 쇽업소버의 씰링을 구성하는 쇽업소버의 씰링부재용 고무 조성물에 관한 것이다.The present invention relates to a rubber composition for a sealing member of a shock absorber, and more particularly to a rubber composition for a sealing member of a shock absorber constituting the sealing of the shock absorber provided in the suspension.

본 발명은 쇽업소버의 씰링부재용 고무 조성물에 관한 것으로, 더욱 상세하게는 자동차 현가장치에 구비된 쇽업소버 내에 형성된 오일의 유실을 방지하는 오일 링이나 밀봉 부재 등의 쇽업소버의 씰링부재용 고무 조성물에 관한 것이다.The present invention relates to a rubber composition for a sealing member of a shock absorber, and more particularly, to a rubber composition for a sealing member of a shock absorber such as an oil ring or a sealing member that prevents loss of oil formed in the shock absorber provided in an automobile suspension. It is about.

자동차 현가장치(suspension system)는 자동차 주행 중에 발생하는 진동 및 충격이 차체와 운전자에게 전달되지 않게 하고, 주행 안정성을 향상시키기 위하여 차체와 타이어 사이에 설치되는 완충장치이다. 이러한 현가장치를 구성하는 부품 중 하나로 쇽업소버(Shock absorber)가 있으며, 이러한 쇽업소버가 외부의 충격을 흡수하는 통상적인 방식으로 모노튜브 방식이 있다. 모노튜브 방식 쇽업소버는 튜브와, 상기 튜브의 내측으로 삽입되고 타단은 튜브의 상단을 통해 외측으로 연장된 피스톤로드와, 상기 튜브의 하부 내측에서 오일이 충진되는 상부의 압축챔버와, 가 스가 충진되는 하부의 가스챔버와, 상기 압축챔버와 가스챔버를 구획하면서 상하이동하게 되는 분리피스톤을 구비한다. 이러한 분리피스톤에는 오일링이 형성되고, 피스톤로드와 튜브가 접촉되는 영역에는 씰링부재가 형성된다.The suspension system is a shock absorber installed between the vehicle body and the tire to prevent vibrations and shocks generated while driving the vehicle from being transmitted to the vehicle body and the driver, and to improve driving stability. One of the components constituting the suspension device is a shock absorber (Shock absorber), and the conventional shock absorber absorbs the external shock is a monotube method. The monotube type shock absorber includes a tube, a piston rod inserted into the inside of the tube and the other end extending outward through the upper end of the tube, an upper compression chamber filled with oil in the lower inside of the tube, and filled with gas. It is provided with a gas chamber in the lower portion, and the separation piston which is moved while moving the partitioning the compression chamber and the gas chamber. An oil ring is formed in the separation piston, and a sealing member is formed in an area where the piston rod and the tube contact each other.

최근에는 자동차의 성능이 고출력화 및 고속화되고, 이에 따라 높은 충격과 강한 압력이 쇽업소버로 전달되는데, 이러한 강한 압력은 피스톤로드에 전달되고, 피스톤로드에 전달된 강한 압력은 씰링부재에 전달된다.In recent years, the performance of automobiles has become higher and higher, and thus high shocks and strong pressures are transmitted to the shock absorbers. Such strong pressures are transmitted to the piston rods, and strong pressures transmitted to the piston rods are transmitted to the sealing members.

일반적인 상기 씰링부재는 높은 압력을 견뎌내기 어려운 문제점이 있다. 따라서, 높은 압력이 반복적으로 작용하에 의해 씰링부재가 손상되면, 피스톤로드가 튜브와 반복적으로 접촉하게 되다가 결국에는 파손된다. 이에 따라, 쇽업소버가 외부의 충격이나 진동을 흡수하지 못하게 되어, 외부의 충격이나 진동이 차량 몸체로 직접 전달되기 때문에 자동차의 주행성능이 떨어지는 것은 물론이고, 승차감 및 안정성이 나빠지게 된다.In general, the sealing member has a problem that is difficult to withstand high pressure. Therefore, if the sealing member is damaged by high pressure repeatedly, the piston rod repeatedly comes into contact with the tube and eventually breaks. As a result, the shock absorber does not absorb external shocks or vibrations, and the external shocks or vibrations are directly transmitted to the vehicle body, thereby degrading driving performance of the vehicle and deteriorating ride comfort and stability.

이와 같은 문제점을 해결하기 위해, 종래의 쇽업소버의 씰링부재용 고무 조성물보다 내마모성 및 내구성이 강한 쇽업소버의 씰링부재용 고무 조성물이 요구된다.In order to solve such a problem, there is a need for a rubber composition for a sealing member of a shock absorber having a higher wear resistance and durability than the conventional rubber composition for a sealing member of a shock absorber.

본 발명은 내마모성과 내구성이 개선된 쇽업소버의 씰링부재용 고무 조성물을 제공하는 것을 목적으로 한다.It is an object of the present invention to provide a rubber composition for a sealing member of a shock absorber having improved wear resistance and durability.

따라서, 본 발명에 일 실시예에 따른 쇽업소버의 씰링부재용 고무 조성물은: 폴리머와; 상기 폴리머 100 중량부에 대하여 95 내지 115 중량부로 이루어진 충진제와; 상기 폴리머 100 중량부에 대하여 5 내지 10 중량부로 이루어진 노화방지제와; 상기 폴리머 100 중량부에 대하여 5 내지 10 중량부로 이루어진 가교조제와; 상기 폴리머 100 중량부에 대하여 5 내지 10 중량부로 이루어진 가교제와; 상기 폴리머 100 중량부에 대하여 10 내지 20 중량부로 이루어진 가소제;를 구비한다.Accordingly, the rubber composition for sealing member of the shock absorber according to an embodiment of the present invention comprises: a polymer; A filler consisting of 95 to 115 parts by weight based on 100 parts by weight of the polymer; Anti-aging agent consisting of 5 to 10 parts by weight based on 100 parts by weight of the polymer; A crosslinking aid consisting of 5 to 10 parts by weight based on 100 parts by weight of the polymer; 5 to 10 parts by weight based on 100 parts by weight of the polymer; It comprises a plasticizer consisting of 10 to 20 parts by weight based on 100 parts by weight of the polymer.

본 실시예의 쇽업소버의 씰링부재용 고무 조성물은 종래의 씰링 고무 조성물보다 내마모성과 내구성이 향상됨으로서, 본 발명의 실시예에 따른 쇽업소버의 씰링부재용 고무 조성물로 속업소버용 씰링을 형성하면, 자동차의 성능이 고출력화와 고속화되어 많은 진동과 충격이 발생하게 되더라도, 쇽업소버의 씰링부재가 파손되지 않아서 쇽업소버 내의 오일이 새거나 쇽업소버의 성능 저하를 방지할 수 있는 효과가 있다.The rubber composition for the sealing member of the shock absorber of the present embodiment has improved wear resistance and durability than the conventional sealing rubber composition, and when the sealing composition for the absorber is formed from the rubber composition for the sealing member of the shock absorber according to the embodiment of the present invention, Even if the performance of high output and high speed causes a lot of vibration and shock, the sealing member of the shock absorber is not damaged, so that oil in the shock absorber or the performance of the shock absorber can be prevented.

Will understand. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

이하 첨부된 도면을 참조하여, 바람직한 실시예에 따른 본 발명을 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 통상적인 자동차용 현가장치의 일 예를 도시한 도면이다.1 is a view showing an example of a conventional vehicle suspension.

자동차용 쇽업소버(10)에 대해 개략적으로 설명하자면, 자동차용 쇽업소버(10)는 튜브(11)와, 피스톤로드(12)와, 피스톤밸브(13)와, 분리피스톤(14)과, 로 드가이드(16)를 구비한다.For the automotive shock absorber 10 schematically, the automotive shock absorber 10 includes a tube 11, a piston rod 12, a piston valve 13, a separation piston 14, and a furnace. The guide guide 16 is provided.

피스톤로드(12)는 튜브(11) 내측으로 삽입되고 타단은 튜브(11)의 상단을 통해 외측으로 연장된다.The piston rod 12 is inserted into the tube 11 and the other end extends outward through the top of the tube 11.

피스톤밸브(piston valve)(13)는 피스톤로드(piston rod)(12)와, 피스톤로드(12)의 하측에 설치되어 튜브(11) 내부를 상부의 인장챔버(rebound chamber)(17a)와 하부의 압축챔버(compression chamber)(17b)로 구획시키며 그 몸체에는 인장챔버(17a)와 압축챔버(17b)간의 오일 유동을 위한 유로(13a)가 형성되어 있다.A piston valve 13 is installed on the piston rod 12 and the lower side of the piston rod 12 so that the inside of the tube 11 is extended to the upper rebound chamber 17a and the lower part. It is divided into a compression chamber (17b) of the body is formed in the body passage 13a for oil flow between the tension chamber (17a) and the compression chamber (17b).

분리피스톤(14)은 튜브(11) 내부에 위치하여 상부의 압축챔버(17b)와 하부의 가스챔버(gas chamber)(18)를 구획시킨다.Separation piston 14 is located inside the tube 11 to partition the upper compression chamber (17b) and the lower gas chamber (gas chamber) (18).

로드가이드(rod guide)(16)는 분리피스톤(14)과, 튜브(11)의 상단에서 피스톤로드(12)를 습동 지지하도록 구비한다.The rod guide 16 is provided to slide-support the separation piston 14 and the piston rod 12 at the upper end of the tube 11.

상기와 같은 구조로 이루어진 쇽업소버(10)의 동작 과정은, 차량 주행에 따라 노면으로부터 충격이 입력되면, 피스톤로드(12)가 상하로 왕복 이동하게 되고, 이에 따라 피스톤밸브(13)의 내부에 형성된 유로(13a)를 통해 상부의 인장챔버(17a)와 하부의 압축챔버(17b)간에 오일이 이동하여 흐르면서 입력된 충격을 완화시키는 감쇠력을 발생시키게 된다.In the operation process of the shock absorber 10 having the above-described structure, when an impact is input from the road surface as the vehicle travels, the piston rod 12 reciprocates up and down, and thus the inside of the piston valve 13 The oil flows between the upper tension chamber 17a and the lower compression chamber 17b through the formed flow path 13a to generate a damping force to alleviate the input shock.

이 경우, 쇽업소버의 씰링부재(100)는 피스톤로드(12)와 튜브(11)사이에 형성되어 외부로부터 이물질이 유입되는 것을 방지하기도 하고, 내부의 오일이 외부로 유출되는 것을 방지한다. 이러한 쇽업소버의 씰링부재(100)는 제조사의 의도에 따라 복수의 부재로 이루어질 수 있으며, 일체형으로 형성될 수도 있다.In this case, the sealing member 100 of the shock absorber is formed between the piston rod 12 and the tube 11 to prevent foreign substances from flowing in from the outside, and to prevent the oil inside from leaking to the outside. The sealing member 100 of the shock absorber may be made of a plurality of members according to the manufacturer's intention, it may be formed integrally.

상술한 자동차용 쇽업소버(10)에 있어서, 쇽업소버의 씰링부재(100)용 고무 조성물은 폴리머와, 충진제와, 노화방지제와, 가교조제와, 가교제와, 가소제를 포함하여 이루어진다.In the above-described automotive shock absorber 10, the rubber composition for sealing member 100 of the shock absorber comprises a polymer, a filler, an anti-aging agent, a crosslinking aid, a crosslinking agent, and a plasticizer.

폴리머는 일반적인 아크릴로니트릴과 부타디엔과의 공중합으로 만들어지는 합성 고무로 이루어질 수 있다. 이러한 합성 고무는 내유성과 내마모성이 강하여 내유성과 내마모성을 필요로 하는 씰링 부재에 주로 사용된다.The polymer may be made of synthetic rubber made by copolymerization of common acrylonitrile and butadiene. Such synthetic rubbers are mainly used for sealing members that have high oil resistance and wear resistance and require oil resistance and wear resistance.

충진제는 폴리머의 접착성을 향상시키는 한편, 가공성 및 보강성을 높이기 위한 것이다. 본 실시예에 따르면, 충진제는 폴리머 100 중량부에 대하여 95 내지 115 중량부로 이루어진 것이 바람직하다.Fillers are intended to improve the adhesion of the polymer while improving processability and reinforcement. According to this embodiment, the filler is preferably composed of 95 to 115 parts by weight based on 100 parts by weight of the polymer.

노화방지제(antioxidant)는 유기고분자 재료의 노화를 방지하는 역할을 한다. 노화방지제는 산화방지제와 같은 작용을 갖는 것이 많기 때문에 산화방지제라고도 한다. 노화방지제는 노화현상의 주요 인자인 산소에 의해서 자동 산화되는 연쇄반응을 정지시키는 작용을 한다. 본 실시예에 따르면, 노화방지제는 폴리머 100 중량부에 대하여 5 내지 10 중량부로 이루어지는 것이 바람직하다.Antioxidants serve to prevent aging of organic polymeric materials. Antioxidants are also called antioxidants because they often have the same effect as antioxidants. Antioxidants act to stop the chain reaction, which is automatically oxidized by oxygen, a major factor in aging. According to this embodiment, the anti-aging agent is preferably composed of 5 to 10 parts by weight based on 100 parts by weight of the polymer.

가교조제는 폴리머의 가교 속도를 증가시키는 한편, 측쇄(side chain) 반응을 방지하여 가교 밀도를 증가시키기 위한 것이다. 본 실시예에 따르면, 가교조제는 폴리머 100 중량부에 대하여 5 내지 10 중량부로 이루어지는 것이 바람직하다.Crosslinking aids are intended to increase the crosslinking speed of the polymer while preventing side chain reactions to increase the crosslinking density. According to this embodiment, it is preferable that the crosslinking aid consists of 5 to 10 parts by weight based on 100 parts by weight of the polymer.

가교제(cross-linking agent)는 상기 폴리머를 구성하는 단량체들을 상호 가교(cross-link)하는 기능을 한다. 본 실시예에 따르면, 가교제는 폴리머 100 중량 부에 대하여 5 내지 10 중량부로 이루어지는 것이 바람직하다.Cross-linking agents function to cross-link the monomers constituting the polymer. According to this embodiment, it is preferable that the crosslinking agent consists of 5-10 weight part with respect to 100 weight part of polymers.

가소제는 상기 폴리머를 유연하게 해주는 역할을 한다. 일반적으로 가소제라 함은 염화비닐과 아세트산비닐 같은 열가소성 플라스틱에 첨가하여 열가소성을 증대시킴으로써 고온에서 성형가공을 용이하게 하는 유기물질로, 유연성을 주는 연화제(softener)와 유사한 역할을 한다. 가소제의 작용을 예를 들어 간단히 설명하면, 플라스틱은 긴 끈 같은 분자가 모여서 된 것으로, 분자 사이에 서로 끌어당기는 힘이 강할수록 딱딱해진다. 이 경우 분자 사이에 가소제가 끼어들면 플라스틱 분자 사이의 직접 끌어당기는 힘이 약해져 잘 휘게 된다. 그러므로 가소제는 상기 폴리머에 잘 섞일 수 있는 성질, 즉 섞임성이 있는 것이 유리하다. 본 실시예에 따르면, 가소제는 폴리머 100 중량부에 대하여 10 내지 20 중량부로 이루어지는 것이 바람직하다.Plasticizers serve to soften the polymer. In general, plasticizers are organic materials that are added to thermoplastics such as vinyl chloride and vinyl acetate to increase thermoplasticity, thereby facilitating molding at high temperatures, and play a role similar to softeners that give flexibility. For example, the plasticizer is a simple description of a long string of string-like molecules, the harder the pull between each other. In this case, when the plasticizer is inserted between the molecules, the direct pulling force between the plastic molecules is weakened, which causes the plastic to bend well. It is therefore advantageous for the plasticizer to be well mixed, i.e., blendable, with the polymer. According to this embodiment, the plasticizer preferably comprises 10 to 20 parts by weight with respect to 100 parts by weight of the polymer.

한편, 충진제는 실리콘 디옥사이드(Silicon dioxide)와 실리콘 카바이드(Silicon carbide)로 이루어진 것이 바람직하다. 일반적으로 보강성을 향상시키는 요인으로는 충진의 입자경 크기, 구조, 입자 표면 성질 등이 영향을 미치는 데, 화이트 카본(White Carbon)이라고 하는 실리콘 디옥사이드와 실리콘 카바이드는 고무와 충전제 개연에서의 작용력을 향상시켜 고무와의 가교밀도를 증가시키고 이는 고무의 보강성을 향상시키는 역할을 한다.On the other hand, the filler is preferably made of silicon dioxide (Silicon dioxide) and silicon carbide (Silicon carbide). In general, the reinforcing properties are influenced by the particle size, structure, and particle surface properties of the filling.Silicone dioxide and silicon carbide, called white carbon, improve the action of rubber and filler fumes. To increase the crosslinking density with the rubber, which serves to improve the reinforcement of the rubber.

본 실시예에 따른 쇽업소버의 씰링부재(100)용 고무 조성물에는 상기와 같은 물질이 포함됨으로서, 쇽업소버의 씰링부재(100)용 고무 조성물의 내마모성 및 내구성을 향상시킬 수 있다. 상기와 같은 본 발명에 따른 쇽업소버의 씰링부재(100) 용 고무 조성물이 종래의 쇽업소버의 씰링부재용 고무 조성물보다 내마모성과 내구성이 우수하다는 것은 아래 표 1과 표 2에 의해 더욱 명확하게 이해될 수 있다.Since the rubber composition for the sealing member 100 of the shock absorber according to the present embodiment includes the above materials, it is possible to improve wear resistance and durability of the rubber composition for the sealing member 100 of the shock absorber. The rubber composition for the sealing member 100 of the shock absorber according to the present invention as described above is superior to the wear resistance and durability than the rubber composition for the sealing member of the conventional shock absorber will be more clearly understood by Table 1 and Table 2 below.
