Description
본 발명은 대기압 플라즈마를 이용한 알루미늄 표면의 처리 방법 및 이에 의해 처리된 알루미늄을 포함하는 본디드 피스톤씰에 관한 것이다.The present invention relates to a method for treating an aluminum surface using atmospheric pressure plasma and to a bonded piston seal comprising aluminum treated by the method.
종래의 피스톤씰은 고무립과 철(Fe)로 구성된 철계 금속 보강링을 일체로 조합한 링 형상으로, 하우징의 내벽과 접하는 부위에 배치하여 작동유가 외부로 새어나가지 않도록 밀봉하는 장치이며, 피스톤의 작동 유압과 리턴 스프링(return spring)에 의해 피스톤 왕복 운동을 전달하는 장치로 자동차 등 광범위한 분야에 사용되고 있다.The conventional piston seal is a ring shape in which a rubber lip and an iron-based metal reinforcing ring composed of iron (Fe) are integrally combined. It is a device that transmits the reciprocating motion of a piston by operating hydraulic pressure and a return spring, and is used in a wide range of fields such as automobiles.
이와 같은 피스톤씰은 제조 과정 중에서 상기 고무립과 상기 금속 보강링의 접착성을 높이기 위하여 상기 금속 보강랑의 표면에 부착된 유지분을 제거하는 탈지 작업을 실시한 다음 인산염 피막(Phosphating)을 형성하게 되는데, 이때 인산염 피막이 형성된 표면에 접착제가 도포된다. 접착제가 도포된 상기 금속 보강링은 다음 공정에서 상기 고무립과 일체화되는 공정을 거쳐 피스톤씰이 제조된다.In order to increase the adhesion between the rubber lip and the metal reinforcing ring during the manufacturing process of the piston seal, a degreasing operation is performed to remove the oil and fat attached to the surface of the metal reinforcing ring, and then a phosphate film is formed. , At this time, an adhesive is applied to the surface on which the phosphate film is formed. The metal reinforcing ring to which the adhesive is applied is integrated with the rubber lip in the next process to manufacture a piston seal.
이때 피스톤씰의 상기 금속 보강링과 상기 고무립을 가류시키는 공정 과정에서 접착 불량이 발생하면 완성된 피스톤씰이 작동 유압과 리턴 스프링의 물리적인 힘으로 상기 금속 보강링과 상기 고무립이 분리되어 파손될 수 있다. 그러면 피스톤의 오일이 손실되어 하우징 내의 압력이 저하되고 그로 인해 자동차의 변속 기능에 치명적인 결함이 발생할 수 있으며, 연료 소비가 증가하는 등의 문제점을 야기시킨다.At this time, if adhesion failure occurs in the process of vulcanizing the metal reinforcing ring and the rubber lip of the piston seal, the completed piston seal may be damaged by separating the metal reinforcing ring and the rubber lip with the operating hydraulic pressure and the physical force of the return spring. can Then, the oil in the piston is lost and the pressure in the housing is lowered, which may cause a fatal defect in the transmission function of the vehicle and cause problems such as increased fuel consumption.
최근에는 연비 향상을 위한 자동차 경량화의 요구에 따라 알루미늄으로 제조된 금속 보강링에 홈을 가공하고, D-링 형태의 고무링을 조립한 형태의 피스톤씰로 사용하고 있다.Recently, in response to the demand for weight reduction in automobiles for improving fuel efficiency, a groove is machined on a metal reinforcing ring made of aluminum, and a rubber ring in the form of a D-ring is used as an assembled piston seal.
그러나 이러한 종래 기술은 상기 홈을 가공함과 더불어 복잡한 조립 공정을 거치기 때문에 고무립을 금속 보강링에 접착시키는 피스톤씰보다 가격 경쟁력이 떨어질 뿐만 아니라, 코킹(Cocking. 작동유압이 불균일하게 유입됨으로 인해 발생하는 피스톤씰의 이상 동작) 현상으로 인해 조립된 D-링이 홈에서 이탈되면서 피스톤씰이 파손되어 자동차의 변속 기능에 치명적인 결함을 발생시키는 문제가 있다.However, in this prior art, because the groove is processed and a complicated assembly process is performed, the price competitiveness is lower than that of the piston seal that bonds the rubber lip to the metal reinforcing ring. There is a problem that the assembled D-ring is separated from the groove due to the abnormal operation of the piston seal), and the piston seal is damaged, causing fatal defects in the shift function of the vehicle.
본 발명은 상기 종래 기술상의 요구를 충족할 수 있는 본디드 피스톤씰의 제조에 응용될 수 있는 알루미늄 및 고무의 접착 방법을 개발하고자 연구한 결과, 플라즈마를 이용할 경우 접착성이 향상될 수 있다는 것을 확인하였으므로, 이에 대기압 플라즈마를 이용한 접착성이 향상된 본디드 피스톤씰용 알루미늄의 표면 처리 방법을 제공하고자 한다.As a result of research to develop an adhesion method of aluminum and rubber that can be applied to the manufacture of a bonded piston seal that can satisfy the requirements of the prior art, the present invention confirmed that adhesion can be improved when plasma is used Therefore, it is intended to provide a method for surface treatment of aluminum for a bonded piston seal with improved adhesion using atmospheric pressure plasma.
상기의 과제를 해결하기 위하여 본 발명자들은 알루미늄의 표면의 일부에 대기압 플라즈마를 처리하는 단계(S1); 및 상기 대기압 플라즈마가 처리된 표면의 일부에 접착제를 도포하는 단계(S2); 및 상기 접착제를 건조하는 단계(S3)를 포함하는, 대기압 플라즈마를 이용한 본디드 피스톤씰용 알루미늄 표면 처리 방법을 제공한다.In order to solve the above problems, the present inventors process a portion of the surface of aluminum with atmospheric pressure plasma (S1); And applying an adhesive to a portion of the surface treated with atmospheric pressure plasma (S2); and drying the adhesive (S3), providing a method for treating an aluminum surface for a bonded piston seal using atmospheric pressure plasma.
또한, 본 발명은 알루미늄과 고무가 접착되어 있는 본디드 피스톤 씰로서,In addition, the present invention is a bonded piston seal in which aluminum and rubber are adhered,
상기 알루미늄 상에 고무의 가류를 통해 접착된 것이고,It is adhered through vulcanization of rubber on the aluminum,
상기 알루미늄은, 고무의 가류 전에 표면의 일부가 대기압 플라즈마로 처리된 후, 접착제를 도포하여 표면 처리된 것을 특징으로 하는, 본디드 피스톤 씰을 제공한다.The aluminum provides a bonded piston seal, characterized in that the surface is treated by applying an adhesive after a portion of the surface is treated with atmospheric plasma before vulcanization of the rubber.
본 발명에 따른 대기압 플라즈마를 이용한 알루미늄 표면 처리 방법은, 종래 공정이 알루미늄 탈지, 수세 및 Al 피막 공정을 거치면서 발생하는 폐수에 의한 환경 오염 위험성과, 시설 확충에 따른 비용이 필수적이었던 것과 다르게, 폐수가 발생하지 않으며, 외관 손상이 방지될 수 있는 장점이 있다.In the aluminum surface treatment method using atmospheric pressure plasma according to the present invention, the risk of environmental contamination by wastewater generated while the conventional process goes through aluminum degreasing, water washing, and Al film process, and cost due to facility expansion were essential. does not occur, and there is an advantage that damage to the appearance can be prevented.
상기 표면 처리 방법에 의해 접착력이 향상된 알루미늄을 통해 제조된 본디드 피스톤씰은 경량화되어 엔진의 응답속도를 향상시키고 연비를 개선할 수 있으며, 종래 고무링을 조립하는 제조방법과 비교하여 높은 가격 경쟁력을 확보할 수 있다.The bonded piston seal manufactured from aluminum with improved adhesion by the surface treatment method can be lightened to improve the response speed of the engine and improve fuel efficiency, and has high price competitiveness compared to the conventional manufacturing method of assembling rubber rings. can be obtained
