Description

자동변속기 오일 쿨러용 호스{Hose for auto transmission oil cooler}Hose for auto transmission oil cooler

본 발명은 자동변속기 오일 쿨러용 호스에 관한 것으로서, 더욱 상세하게는내ㆍ외면층이 주성분인 염소화된 폴리에틸렌(chlorinated polyethylene, CPE)으로 이루어지며, 내면층과 외면층 사이에 있는 중간층이 보강사로 이루어진 호스에 있어서, 염소화된 폴리에틸렌의 염소함량을 일정범위로 조절하고, 보강사의 각도를 대폭 증가시킴으로써, 종래 에틸렌 아크릴릭 러버(ethylene acrylic rubber, EAR)를 사용한 호스에 비해 제조원가가 매우 저렴하며, 비중이 낮아 기존보다 경량화될 뿐 아니라 불량률이 월등히 감소되고, 내열성, 저온성 등이 우수하며 파열강도가 월등히 우수하여 자동변속기 오일 쿨러용으로 유용한 호스에 관한 것이다.The present invention relates to a hose for an automatic transmission oil cooler, and more particularly, consisting of chlorinated polyethylene (CPE), the inner and outer layers of the main component, the intermediate layer between the inner layer and the outer layer is made of a reinforcement yarn. In the hose, by adjusting the chlorine content of the chlorinated polyethylene to a certain range and by greatly increasing the angle of the reinforcement yarn, the manufacturing cost is very low compared to the hose using ethylene acrylic rubber (EAR), and the specific gravity is low Not only is it lighter than conventional, the defect rate is greatly reduced, it is excellent in heat resistance, low temperature, etc., and excellent in bursting strength, it is related to a hose useful for an automatic transmission oil cooler.

종래 자동변속기 오일 쿨러용 호스로는 내면층이 에틸렌 아크릴릭 러버(ethylene acrylic rubber, EAR)로 이루어지고, 중간에 폴리아미드 66(PA 66)과 같은 보강사가 적층되며, 외면층이 에틸렌 아크릴릭 러버로 이루어진 호스를 사용하여 왔다.In the conventional automatic transmission oil cooler hose, the inner layer is made of ethylene acrylic rubber (ethylene acrylic rubber, EAR), the reinforcement such as polyamide 66 (PA 66) is laminated in the middle, the outer layer is made of ethylene acrylic rubber Hose has been used.

일반적으로 자동변속기 오일 쿨러용 호스는 호스 내부에 이형제 및 이물질이 없고, 오일 누설을 방지하며, 자동변속기 오일이나 엔진 오일 등에 대한 내유성이 있고, 내열성, 내구성 및 내후성이 우수한 특성을 지녀야 한다.In general, the hose for the automatic transmission oil cooler should have no releasing agent and foreign substances in the hose, to prevent oil leakage, oil resistance to automatic transmission oil or engine oil, etc., and have excellent heat resistance, durability and weather resistance.

그런데, 상기와 같이 구성된 종래의 호스는 이와 같은 요구조건에 부합되기는 하지만 고가이며, 저온에서의 성능이 다소 떨어지는 문제가 있었다.By the way, the conventional hose configured as described above is expensive but meets the requirements, there is a problem that the performance at a low temperature is somewhat poor.

한편, 미국의 제너럴 모터스, 포드, 크라이슬러사에서는 자동변속기 오일 쿨러용 호스의 내ㆍ외면층 원료로 염소화된 폴리에틸렌(CPE)를 사용한 바 있으나, 염소함량이 많아(38∼40 %) 저온 성능에서 개선의 여지가 있어 광범위하게 실용화되기에는 무리가 있었다.Meanwhile, General Motors, Ford and Chrysler of the United States used chlorinated polyethylene (CPE) as an inner and outer layer of the hose for automatic transmission oil cooler, but it has a high chlorine content (38-40%) to improve at low temperature performance. There was room for it to be widely available.

이에, 본 발명자들은 저렴한 원료인 염소화된 폴리에틸렌를 사용하되, 기존의 자동변속기 오일 쿨러용 호스의 물성을 보다 향상시키기 위하여 연구 노력하였다. 그 결과, 주원료로 사용되는 염소화된 폴리에틸렌의 염소 함량을 특정 범위로 조절하면 종래에 비하여 내열성, 저온성 등이 우수하고, 또한 일반적으로 사용되는 보강사의 각도를 대폭 수정하면 파열강도가 상승함을 알게되어 본 발명을 완성하였다.Thus, the inventors of the present invention tried to improve the physical properties of the hose for the automatic transmission oil cooler using a cheap material chlorinated polyethylene. As a result, when the chlorine content of the chlorinated polyethylene used as the main raw material is adjusted to a specific range, it is excellent in heat resistance and low temperature compared with the conventional one, and when the angle of the reinforcement generally used is greatly modified, the bursting strength is increased. The present invention was completed.

따라서, 본 발명은 내열성, 저온성 및 파열강도 등이 우수한 자동변속기 오일 쿨러용 호스를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a hose for an automatic transmission oil cooler having excellent heat resistance, low temperature, and burst strength.

본 발명은 내ㆍ외면층이 염소화된 폴리에틸렌을 주성분으로 이루어지며, 내면층과 외면층 사이에 있는 중간층이 보강사로 이루어진 자동변속기 오일 쿨러용 호스에 있어서,In the present invention, the inner and outer layers are made of chlorinated polyethylene as a main component, the intermediate layer between the inner layer and the outer layer is an automatic transmission oil cooler hose made of a reinforcement yarn,

상기 염소화된 폴리에틸렌의 염소함량이 30 ∼ 42 중량%이고, 상기 보강사의 각도가 105 ∼ 130 °인 자동변속기 오일 쿨러용 호스에 그 특징이 있다.The chlorinated polyethylene has a chlorine content of 30 to 42% by weight, and the reinforcing yarn has an characteristic of an automatic transmission oil cooler hose having an angle of 105 to 130 °.

또한, 본 발명은 염소화된 폴리에틸렌 수지를 1, 2차로 가황시켜서 자동변속기 오일 쿨러용 호스를 제조하는 방법에 있어서,In addition, the present invention is a method of manufacturing a hose for an automatic transmission oil cooler by vulcanizing the chlorinated polyethylene resin first and second,

상기 2차 가황과정은 170 ∼ 190 ℃에서 5 ∼ 15분간 진행하는 것을 특징으로 한다.The secondary vulcanization process is characterized in that for 5 to 15 minutes at 170 ~ 190 ℃.

이와 같은 본 발명을 더욱 상세하게 설명하면 다음과 같다.The present invention will be described in more detail as follows.

본 발명은 이 기존 제품과 비교하여 동등 이상의 물성을 나타내고, 비중이 낮아 무게가 가벼우며, 특히 파열강도가 우수하여 자동차 등의 분야에 유용하게 활용될 수 있는 자동변속기 오일 쿨러용 호스에 관한 것이다.The present invention relates to the physical properties of the automatic transmission oil cooler that can be usefully used in the field of the automobile, such as exhibiting more than equivalent physical properties, low specific gravity, low weight, especially excellent burst strength.

본 발명의 자동변속기 오일 쿨러용 호스를 그 성분에 따라 더욱 구체화하여 설명하면 다음과 같다.When explaining the hose for the automatic transmission oil cooler of the present invention in more detail according to the components as follows.

본 발명에서 호스의 내ㆍ외면층에 사용되는 성분으로는 염소화된 폴리에틸렌 외에 활성탄, 저점도 오일, ZnO, 노화 방지제, 가황 촉진제 및 가황제 등이 있다.In the present invention, components used for the inner and outer layers of the hose include activated carbon, low viscosity oil, ZnO, anti-aging agent, vulcanization accelerator and vulcanizing agent, in addition to chlorinated polyethylene.

특히, 본 발명에 따르면 상기 염소화된 폴리에틸렌은 염소가 30 ∼ 42 중량% 함유된 것을 사용하는바, 상기 염소가 30 중량% 미만이 함유된 폴리에틸렌을 사용하면 ATF액(Auto Transmission Fluid)에 내성이 취약하고, 42 중량%를 초과하면 내유성 및 저온성이 급격히 저하되는 문제가 있어 바람직하지 못하다.Particularly, according to the present invention, the chlorinated polyethylene uses 30 to 42% by weight of chlorine. If the polyethylene containing less than 30% by weight of chlorine is used, the resistance to ATF liquid (Auto Transmission Fluid) is weak. In addition, if it exceeds 42% by weight, there is a problem that the oil resistance and low temperature resistance are sharply lowered, which is not preferable.

또한, 가황제는 황(sulphur)을 사용할 수 있으며, 본 발명에서는 염소화된 폴리에틸렌 100 중량부에 대하여 0.9 ∼ 1.1 중량부(PHR)를 첨가하는 것이 바람직하다.Sulfur may also be used, and in the present invention, it is preferable to add 0.9 to 1.1 parts by weight (PHR) based on 100 parts by weight of chlorinated polyethylene.

상기 원료들을 배합하여 공지된 방법으로 염소화된 폴리에틸렌 고무를 제조하되, 통상의 방법과 같이 165 ℃에서 5분간 가황을 실시하지만, 본 발명에서는 특별히 2차 가황단계를 추가하여 170 ∼ 190 ℃에서 5 ∼ 15분간 가황시키는바, 그 이유는 성형 후 탈거시 점착성으로 인해 금형에 붙어 탈착이 안되는 문제를 방지하고, 또한 고무의 탄성을 유지하기 위해 2차 가황을 특별히 수행한다.To prepare the chlorinated polyethylene rubber by a known method by combining the raw materials, but vulcanized at 165 ℃ for 5 minutes as in the usual method, in the present invention by adding a secondary vulcanization step in particular from 5 to 170 ~ 190 ℃ After vulcanization for 15 minutes, the reason is that the secondary vulcanization is carried out in order to prevent the problem of sticking to the mold due to the stickiness during detachment after molding, and also to maintain the elasticity of the rubber.

이와 같이 조성된 염소화된 폴리에틸렌 수지로 내외면층을 형성하고 그 중간층은 통상의 자동변속기 오일 쿨러용 호스에서와 마찬가지로 보강사층을 형성하는바, 도 2에 나타낸 바와 같이 본 발명의 호스 중간층에 사용하는 보강사 섬유의 내각은 보편적인 90°가 아니라 105 ∼ 130°인 것이 본 발명의 특징이며, 보강사 섬유로는 폴리아미드 66 또는 나일론 66을 사용할 수 있다. 이때, 보강사 섬유의 내각을 상기 범위로 조정한 이유는 파열압 및 내압성을 향상시키기 위해서이다.The inner and outer layers are formed of the chlorinated polyethylene resin thus formed, and the intermediate layer forms a reinforcing yarn layer as in the case of a conventional automatic oil cooler hose, and is used in the hose intermediate layer of the present invention as shown in FIG. It is a feature of the present invention that the interior of the reinforcing yarn fibers is 105 to 130 ° instead of the general 90 °, and polyamide 66 or nylon 66 may be used as the reinforcing yarn fibers. At this time, the reason why the internal angle of the reinforcement fiber was adjusted to the above range is to improve the bursting pressure and the pressure resistance.

호스를 구성하는 내면층, 중간층 및 외면층은 통상 그 두께(mm)가 각각 1.0 ∼ 1.3, 0.2 ∼ 0.3, 2.0 ∼2.3인 것이 바람직하다.It is preferable that the thickness (mm) of the inner surface layer, intermediate | middle layer, and outer surface layer which comprise a hose is 1.0-1.3, 0.2-0.3, 2.0-2.3 normally, respectively.

이렇게 하여 제조된 본 발명의 호스는 기존제품의 비중 0.987 보다 월등히 낮은 0.894의 비중을 가지며, 상태물성의 경도가 62 ∼ 66 Hs이고, 전반적인 물성이 기존제품과 동등하거나 그 이상인 것으로 나타났다.The hose of the present invention prepared in this way has a specific gravity of 0.894, which is much lower than the specific gravity of 0.987 of the existing product, the hardness of the state property is 62 ~ 66 Hs, the overall physical properties were found to be equal or more than the existing product.

이하, 본 발명을 실시예에 의거하여 더욱 상세하게 설명하겠는바, 본 발명이 실시예에 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited to Examples.
