정전기 발생을 방지한 타이어{Tire for static electricity generation prevention}Tire for static electricity generation prevention

본 발명은 정전기 발생을 방지한 차량용 타이어에 관한 것으로, 특히 싱글 와인딩(Single Winding) 방식으로 압출 성형되는 타이어에서 타이어의 마모진행과 기타 성능에 관계없이 정전기 발생을 방지한 타이어에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle tire that prevents the generation of static electricity, and more particularly, to a tire that prevents the occurrence of static electricity regardless of the progress of tire wear and other performance in a tire that is extruded by a single winding method.

주지된 바와 같이 차량에 장착되어 주행하는 타이어에는 노면바닥의 마찰, 공기와 차체의 마찰 등으로 인해 차체에 정전기가 쌓이게 되는데, 차체에 쌓인 이러한 정전기는 타이어의 전도성 압출물을 통해 지면으로 어스(Earth) 시키도록 되어 있다.As is well known, tires mounted and running on a vehicle accumulate static electricity on the body due to friction of the road surface, friction between air and the body, and the static electricity accumulated on the body is grounded through the tire's conductive extrudates to the ground. It is supposed to.

즉, 종래 정전기 발생을 방지한 일반적인 타이어를 살펴보면, 도 6에 도시된 바와 같이 노면과 접촉하는 타이어의 트레드(103)에는 전도성 물질인 카본 비임(111)이 압출 성형시에 형성되어 있는바, 이 카본 비임(111)을 통하여 타이어에서 발생하는 정전기를 지속적으로 노면에 어스 시키도록 되어 있다.That is, when looking at a conventional tire that prevents the occurrence of static electricity, as shown in Figure 6, the tread 103 of the tire in contact with the road surface is formed of carbon beam 111, which is a conductive material at the time of extrusion molding, Through the carbon beam 111, the static electricity generated from the tire is to be continuously grounded on the road surface.

이 같은 종래 타이어는 다이 압출방식으로 트레드(103)가 압출될 때 주로 적용하게 되어 있으나, 싱글 와인딩(Single Winding) 압출방식으로 제조되는 트레드 에서 실리카(Silica) 타이어를 제조할 경우 전기 전도성이 나빠서 차량에서 발생하는 전기를 효과적으로 방출하지 못하였다.Such a conventional tire is mainly applied when the tread 103 is extruded by a die extrusion method, but when the silica tire is manufactured from a tread manufactured by a single winding extrusion method, the vehicle has poor electrical conductivity. It did not effectively release the electricity generated by

여기서 싱글 와인딩 압출방식으로 제조되는 타이어는 도 1과 도 2에 도시된 바와 같이 싱글 와인딩 압출기(1)에서 압출되는 실리카 압출물(10)이 드럼(4)에 연속적으로 적층식으로 감기어 실리카 재질의 트레드(103)를 도 5와 같이 갖도록 되어 있기 때문에 차체와 타이어에서 발생한 정전기를 제대로 방출시키지 못한 구조로 되어 있다.In this case, the tire manufactured by the single winding extrusion method is a silica material 10, which is extruded from the single winding extruder 1 and continuously wound on the drum 4, as shown in FIGS. 1 and 2. Since the tread 103 is formed as shown in FIG. 5, the static electricity generated in the vehicle body and the tire is not properly discharged.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 싱글 와인딩 압출방식으로 제조되는 타이어에서 타이어의 마모진행과 상관없고, 기타 타이어 성능저하도 발생하지 않으면서 차체와 타이어에서 발생하고 정전기를 지속적으로 노면으로 어스 시킬 수 있는 정전기 발생을 방지한 타이어를 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the above-mentioned conventional problems, and the tire produced by the single winding extrusion method is irrelevant to the wear progress of the tire, and occurs in the vehicle body and the tire without any deterioration in tire performance and static electricity The object of the present invention is to provide a tire which prevents the occurrence of static electricity which can continuously ground the road.

상기와 같은 목적을 달성하기 위한 본 발명은 싱글 와인딩 압출기를 통하여 실리카 압출물이 압축되어 드럼에 연속적으로 감기면서 실리카 재질의 트레드를 갖는 타이어에 있어서, 상기 실리카 압출물 둘레에는 전도성 카본이 일정두께로 코팅되고, 이 카본으로 코팅된 실리카 압출물이 다층으로 적층되어 전도성 카본이 다층으로 연속 연결되어 이루어진 구조로 되어 있다.In order to achieve the above object, the present invention provides a tire having a silica tread while the silica extrudate is compressed through a single winding extruder and continuously wound on a drum, wherein the conductive carbon has a predetermined thickness around the silica extrudate. The coated carbon-extruded silica extrudates are laminated in multiple layers, and conductive carbon is continuously connected in multiple layers.

상기와 같이 본 발명에 따른 정전기 발생을 방지한 타이어는 타이어의 트레드 마모진행과 상관없이 기타 타이어 성능에도 영향을 끼치지 않으면서 정전기를 지속적으로 방지하는 효과를 지닌다.As described above, the tire of preventing static electricity according to the present invention has an effect of continuously preventing static electricity without affecting other tire performance regardless of progress of tread wear of the tire.
