호스 {Hose}Hose {Hose}

본 고안은 호스에 관한 것으로서, 특히 연질의 호스 외면에 나선형으로 돌출된 돌출부를 형성하고 그 내부에는 경질의 재질로 코어를 형성하며 그 외부에는 특수재질의 내마모성 재질을 코팅한 호스에 관한 것이다.The present invention relates to a hose, and in particular, to a hose formed on the outer surface of the flexible hose protruding helically, the core is formed of a hard material, the outside of the hose coated with a special wear-resistant material.

폴리염화비닐 PVC(polyvinyl chloride)는 염화비닐의 단독 중합체 및 염화비닐을 50% 이상 함유한 혼성중합체를 이른다. 염화비닐수지라고도 불리는 PVC는 각종 조제를 배합하여 열가공되어 제품이 된다. 용도는 대부분 가소제를 첨가한 연질 제품인데 포장용 농업용 등의 시트나 필름 등 아주 넓게 쓰인다. 폴리에틸렌 제품과 비교하여 내한성 신장성은 뒤떨어지나 투명성, 강도에서 우수하다. 압출성형은 전선 피복용 각종 튜브, 호스 등을 제조한다. 경질 제품에서는 압출성형에 의한 수도관의 제조가 가장 중요하다. 흡수성은 없으나 탄력이 있고 약품에 대한 저항력도 크지만 열에는 약하다.Polyvinyl chloride PVC is a homopolymer of vinyl chloride and a copolymer containing at least 50% of vinyl chloride. PVC, also called vinyl chloride resin, is blended with various preparations and thermally processed into a product. It is mostly used as a soft product with added plasticizer, and is widely used for sheets and films such as agricultural products for packaging. Compared to polyethylene products, cold resistance extensibility is inferior but excellent in transparency and strength. Extrusion manufactures various tubes, hoses and the like for wire coating. In rigid products, the production of water pipes by extrusion is of paramount importance. It has no absorbency but is elastic and resistant to chemicals, but weak in heat.

종래의 호스는 폴리염화비닐과 같이 연질로 이루어진 경우에는 그 유연성은 뛰어나나 내구성이 약하여 쉽게 파괴되고 고무 호스와 같이 내구성이 강한 경질로 이루어진 경우에는 내구성이 강하나 유연성이 떨어지는 문제점이 있다.When a conventional hose is made of a soft material such as polyvinyl chloride, its flexibility is excellent, but its durability is weak, and it is easily broken, and when it is made of a hard rigid material such as a rubber hose, there is a problem that durability is low but flexibility is low.

본 고안은 상술한 문제점을 해결할 수 있는 고안으로서, 내부에 유체가 흐를 수 있도록 연질부재로 압출된 호스에 있어서, 상기 호스의 외면에는 나선모양의 돌출부가 연속하여 형성되어 있고, 그 돌출부의 내부에는 경질부재가 나선모양을 따라 삽입되어 있으며, 그 돌출부의 외면에는 내마모성이 뛰어난 경질과 연질의 혼합재질의 특수수지층이 형성되어 있는 호스를 제공한다.The present invention has been made to solve the above problems, in the hose extruded by a soft member so that the fluid flows in the inside, the outer surface of the hose is formed with a spiral projection is continuously formed, the inside of the protrusion The hard member is inserted along the spiral shape, and the outer surface of the protrusion provides a hose having a special resin layer of a hard and soft mixed material having excellent wear resistance.

본 고안에 의한 호스는 전체적으로 연질부재를 사용하였기 때문에 그 유연성이 뛰어난 동시에 경질부재를 사용하여 강도를 증대시키고 외면에 내마모성의 재질을 추가함으로써 내마모성을 향상시킨 호스이다.Since the hose according to the present invention uses a soft member as a whole, it is excellent in its flexibility and at the same time, it increases the strength by using a hard member and improves the wear resistance by adding a wear resistant material to the outer surface.

도 1을 참고하면, 본 고안에 의한 호스(10)는 내부에 유체가 흐를 수 있도록 균일한 유로가 형성되도록 연질부재(20)로 압출되어 있다. 그 연질부재(20)의 외면에는 나선모양의 돌출부(11)가 연속하여 형성되어 있다.Referring to FIG. 1, the hose 10 according to the present invention is extruded into the soft member 20 so that a uniform flow path is formed to allow fluid to flow therein. On the outer surface of the soft member 20, spiral protrusions 11 are formed continuously.

연질부재(20)의 돌출부(11)에는 그 돌출부(11)와 마찬가지로 나선모양으로 그 내부에 경질부재(30)가 형성되어 함께 압출되어 있다.The protruding portion 11 of the soft member 20, like the protruding portion 11, is formed in the shape of a spiral and a hard member 30 is formed therein and extruded together.

또, 돌출부(11)의 외면에는 내마모성이 강한 특수수지층(40)이 그 나선모양의 돌출부(11)를 따라 연속하여 코팅되어 있다.The outer surface of the protrusion 11 is coated with a special wear resistant layer 40 that is highly resistant to wear along the spiral protrusion 11.

연질부재(20)로는 상술한 폴리염화비닐이 사용될 수 있고, 경질부재(30)로는 고무 등이 사용될 수 있다. 그리고 특수수지층(40)으로는 연질과 경질을 배합한 것도 가능할 뿐만 아니라 연질부재(20)에 코팅이 잘되고 내마모성이 강한 재질이면 무난하다.As the soft member 20, the above-described polyvinyl chloride may be used, and the hard member 30 may be rubber or the like. In addition, the special resin layer 40 may be blended with soft and hard as well as a good coating on the soft member 20 and may be a good material having high abrasion resistance.

한편, 도 2는 본 고안의 다른 실시 예에 의한 호스(10')를 보여주고 있다. 도시된 바와 같이 앞선 실시예와 다른 것은 돌출부를 이루지 않는다는 것이다. 즉 연질부재(20')에 돌출부를 형성하지 않고 그 내부에 나선모양으로 경질부재(30')를 삽입하여 압출하고, 그 바깥에 역시 나선형 모양으로 특수수지층(40')를 코팅한 것이다.On the other hand, Figure 2 shows a hose 10 'according to another embodiment of the present invention. As shown, the difference from the previous embodiment is that it does not form a protrusion. That is, the flexible member 20 'does not form a protrusion, and inserts the hard member 30' in a spiral shape therein and extrudes, and the special resin layer 40 'is coated in a spiral shape outside thereof.

도 1은 본 고안에 의한 호스의 부분 단면도이다.1 is a partial cross-sectional view of a hose according to the present invention.

도 2는 본 고안에 의한 다른 실시예의 부분 단면도이다.2 is a partial cross-sectional view of another embodiment according to the present invention.
