본 발명은 니트릴부타디엔러버를 주성분으로 하는 내면고무, 폴리에틸렌계 편상섬유층, 및 클로로프렌 러버를 주성분으로 하는 외면고무로 이루어진 파워 스티어링 호스 조성물에 있어서,The present invention relates to a power steering hose composition comprising an inner rubber mainly composed of nitrile butadiene rubber, a polyethylene-based fibrous layer, and an outer rubber mainly composed of chloroprene rubber,

상기 내면고무 및 외면고무는 Cl 함량이 35∼40 중량%인 클로리네이티드 폴리에틸렌 고무를 주성분으로 함유하는 저압용 파워 스티어링 호스 조성물을 그 특징으로 한다.The inner rubber and the outer rubber are characterized by a low pressure power steering hose composition containing a chlorinated polyethylene rubber having a Cl content of 35 to 40% by weight as a main component.

이하, 본 발명을 더욱 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.

본 발명은 내열성 및 내구성이 우수한 저압용 파워 스티어링 호스 조성물을 제공하는 것이다.The present invention provides a low pressure power steering hose composition having excellent heat resistance and durability.

이러한 본 발명의 호스 조성물은 내면고무, 폴리에틸렌계 편상섬유층 및 외면고무로 구성되어 있다.The hose composition of the present invention is composed of an inner rubber, a polyethylene-based fibrous layer and an outer rubber.

상기 내면고무 및 외면고무는 모두 Cl 함량이 35∼40 중량%인 클로리네이티드 폴리에틸렌 러버(Chlorinated Polyethylene Rubber)를 주성분으로 사용하는 특징이 있다. 이로써, 내열성 및 내구성을 향상시켜 자동차의 고출력으로 인한 온도 상승문제를 해결할 수 있다. 이때, 상기 Cl의 함량이 35 중량% 미만이면 내열성 (135℃)이 취약한 문제가 있고, 40 중량%를 초과하면 내열성은 우수하지만 저온 (-40℃)에서 열세를 나타낸다.The inner rubber and the outer rubber are both characterized by the use of chlorinated polyethylene rubber (Chlorinated Polyethylene Rubber) having a Cl content of 35 to 40% by weight. As a result, it is possible to improve the heat resistance and durability to solve the temperature rise problem due to the high power of the vehicle. At this time, if the Cl content is less than 35% by weight, there is a problem that the heat resistance (135 ℃) is weak, if it exceeds 40% by weight is excellent in heat resistance but low temperature (-40 ℃) is poor.

상기 내면고무는 상기 주성분으로 사용하는 클로리네이티드 폴리에틸렌 고무 외에 카본블랙, 프로세스 오일, 산화아연, 노화방지제, 가류촉진제, 및 가류제를 함유하고 있다.The inner rubber contains carbon black, process oil, zinc oxide, antioxidant, vulcanization accelerator, and vulcanizing agent in addition to the chlorinated polyethylene rubber used as the main component.

또한, 상기 외면고무 역시 상기 주성분으로 사용하는 클로리네이티드 폴리에틸렌 고무 외에 카본블랙, 프로세스 오일, 산화아연, 노화방지제, 가류촉진제, 및 가류제를 함유하고 있다.The outer rubber also contains carbon black, process oil, zinc oxide, antioxidant, vulcanization accelerator, and vulcanizing agent in addition to the chlorinated polyethylene rubber used as the main component.

상기 내면고무 및 외면고무에 사용되는 카본블랙은 보강성 및 고충진을 위해사용하며, 바람직하게는 고속 압출로(Fast Extrusion Furnace)를 사용한다. 이때 상기 카본 블랙으로 만약 종래의 카본 블랙인 세미-강화로(semi-resinforcing furnace)를 사용하면 혼합(Mixing)이 불안정하여 품질 문제가 발생한다. 상기 카본블랙의 함량은 클로리네이티드 폴리에틸렌 러버 100 중량부에 대하여 50 ∼ 65 중량부로 사용하는 것이 바람직하며, 그 함량이 50 중량부 미만이면 강도가 떨어져서 내충격성이 취약하고, 65 중량부를 초과하면 강도가 우수하여 내충격성은 유리하지만, 고무의 특성인 탄성력이 떨어져 내구력에서 균열발생 등의 기능 저하가 발생한다.The carbon black used for the inner rubber and the outer rubber is used for reinforcement and high filling, and preferably, a fast extrusion furnace is used. In this case, if the carbon black is a semi-resinforcing furnace, which is a conventional carbon black, the mixing is unstable and a quality problem occurs. The content of the carbon black is preferably used in an amount of 50 to 65 parts by weight based on 100 parts by weight of the chlorinated polyethylene rubber, and if the content is less than 50 parts by weight, the strength is poor and the impact resistance is weak. It is excellent in impact resistance, but the elastic force, which is a characteristic of rubber, is poor, resulting in functional degradation such as cracking in durability.

또한, 상기 내면고무 및 외면고무에 사용되는 프로세스 오일은 저점도 오일을 사용하는 것이 바람직하며, 그 함량은 클로리네이티드 폴리에틸렌 러버 100 중량부에 대하여 28 ∼ 32 중량부로 사용한다.In addition, the process oil used for the inner rubber and the outer rubber is preferably to use a low viscosity oil, the content is used in 28 to 32 parts by weight based on 100 parts by weight of the chlorinated polyethylene rubber.

상기 내면고무 및 외면고무에 사용되는 산화아연(ZnO)은 고무류의 물성, 특히 탄성, 영구변형율 및 내열성을 더욱 촉진시키기 위한 가교촉진제로 사용한다. 상기 산화아연(ZnO)의 함량은 클로리네이티드 폴리에틸렌 러버 100 중량부에 대하여 내면고무는 23 ∼ 27 중량부로, 외면고무는 18 ∼ 22 중량부로 사용할 수 있다.Zinc oxide (ZnO) used for the inner rubber and the outer rubber is used as a crosslinking accelerator for further promoting physical properties of rubbers, particularly elasticity, permanent strain and heat resistance. The zinc oxide (ZnO) may be used in an amount of 23 to 27 parts by weight of the inner rubber and 18 to 22 parts by weight of the outer rubber with respect to 100 parts by weight of the chlorinated polyethylene rubber.

상기 내면고무 및 외면고무에 사용되는 노화방지제는 주성분으로 사용하는 고분자외에 내열성을 향상시키기 위해 사용한다. 상기 노화방지제로는 2-하이드로(2D)를 사용할 수 있으며, 그 함량은 클로리네이티드 폴리에틸렌 러버 100 중량부에 대하여 18∼22 중량부로 사용한다. 상기 노화방지제의 함량이 18 중량부 미만이면 내열성이 불리해지고, 22 중량부를 초과하면 내열성은 우수하지만 저온 및 장기 내구력이 불리하다.The anti-aging agent used for the inner rubber and the outer rubber is used to improve heat resistance in addition to the polymer used as the main component. As the anti-aging agent, 2-hydro (2D) may be used, and the content thereof is used in an amount of 18 to 22 parts by weight based on 100 parts by weight of the chlorinated polyethylene rubber. If the content of the anti-aging agent is less than 18 parts by weight, the heat resistance is disadvantageous, if it exceeds 22 parts by weight, the heat resistance is excellent but low temperature and long-term durability is disadvantageous.

상기 내면고무 및 외면고무에 사용되는 가류촉진제는 고무의 경화속도를 조절하기 위해 사용한다. 상기 가류촉진제로는 테트라-디하이드로(TD)를 사용할 수 있으며, 그 함량은 클로리네이티드 폴리에틸렌 러버 100 중량부에 대하여 2.5 ∼ 3.5 중량부로 사용할 수 있다.The vulcanization accelerator used for the inner rubber and the outer rubber is used to control the curing rate of the rubber. Tetra-dihydro (TD) may be used as the vulcanization accelerator, and the content thereof may be 2.5 to 3.5 parts by weight based on 100 parts by weight of the cloned polyethylene rubber.

상기 내면고무 및 외면고무에 사용되는 가류제는 경화성 향상을 위해 사용한다. 상기 가류제로는 SO4를 사용할 수 있으며, 그 함량은 클로리네이티드 폴리에틸렌 러버 100 중량부에 대하여 0.5 ∼ 0.6 중량부로 사용한다.The vulcanizing agent used for the inner rubber and the outer rubber is used to improve the hardenability. SO 4 may be used as the vulcanizing agent, and the content thereof may be used in an amount of 0.5 to 0.6 parts by weight based on 100 parts by weight of the cloned polyethylene rubber.

그밖에, 통상의 파워 스티어링 호스 조성물에 사용될 수 있는 첨가제를 필요에 따라 선택하여 사용할 수 있다.In addition, additives that can be used in conventional power steering hose compositions can be selected and used as necessary.

이와 같이, 본 발명의 호스 조성물은 내면고무 및 외면고무의 주성분으로 Cl이 특정량 함유된 클로리네이티드 폴리에틸렌 러버를 사용함으로써 내열성 및 내구성을 크게 향상시켜 자동차의 엔진에 적용시 온도상승을 방지하여 비용절감을 꾀할 수 있다.As described above, the hose composition of the present invention uses a cloned polyethylene rubber containing Cl as a main component of the inner rubber and the outer rubber, thereby greatly improving heat resistance and durability, thereby preventing a temperature increase when applied to an engine of a vehicle. Savings can be made.
