본 발명은 3중 구조로 된 트레드부를 갖는 겨울용 스터드레스 타이어에 관한 것으로, 보다 상세하게는 트레드부가 기존의 부타디엔 고무와 천연고무 혼합물로 이루어지되, 주로 천연고무의 비율에 따라 3중 구조로 구성되고, 동시에 블럭이 다소 작고 조밀하게 설계된 트레드 패턴을 가짐으로써 겨울용 트레드로서의 특성과 빙상, 설상에서의 제동력 및 구동력의 향상이 기대되는 겨울용 스터드레스 타이어에 관한 것이다.The present invention relates to a winter studless tire having a tread portion having a triple structure, and more particularly, the tread portion is made of a conventional butadiene rubber and natural rubber mixture, and mainly composed of a triple structure according to the ratio of natural rubber. In addition, the winter stud tire is expected to improve the characteristics of the winter tread, the braking force and the driving force on the ice and snow, as the block has a slightly smaller and densely designed tread pattern.

타이어중 겨울용 타이어의 특징은 빙상, 설상에서의 제동 및 구동능력을 향상시키고 저온에서의 고무특성을 유지시키기 위해 저온특성이 우수한 부타디엔(BR) 고무를 많이 사용하고 충진제의 양을 적게 하여 부드러운 고무를 사용한다. 그리고, 트레드의 패턴블럭을 넓게 하고 커프를 많이 삽입하여 지면과의 접촉면을 크게 하는 것이 특징이다.The characteristics of winter tires among tires include soft butadiene (BR) rubber with high temperature characteristics and small amount of filler to improve braking and driving ability on ice and snow, and to maintain rubber characteristics at low temperature. use. And, it is characterized by widening the pattern block of the tread and inserting a lot of cuffs to increase the contact surface with the ground.

또한 더 좋은 성능향상을 위해 강철 스파이크핀을 사용하기도 한다. 그러나, 스파이크 타이어의 경우 도로면에 대한 강철핀과의 충격으로 도로파손과 그에 따른 분진, 소음에 의한 환경문제가 최근 크게 대두되고 있어 스파이크핀을 사용하지 않는 스파이크레스 타이어가 각광을 받고 있는 추세이다. 이러한 스파이크레스 타이어의 성능을 향상시키고자 트레드 표면에 마이크로 셀을 다량 함유한 발포고무층을 사용하기도 하고, 고무에 단섬유, 셀룰로오스조각, 엔지니어링 플라스틱조각 또는 무기필러로 세라믹 가루, 철가루, 돌가루 등 다양한 재료를 혼합하여 사용하기도 한다.It also uses steel spike pins for better performance. However, in the case of spike tires, environmental problems due to road damage, dust and noise caused by impacts with steel pins on the road surface have recently emerged, and spikeless tires without spike pins are in the spotlight. . In order to improve the performance of these spikeless tires, a foamed rubber layer containing a large amount of microcells is used on the surface of the tread, and short fibers, cellulose pieces, engineering plastic pieces or inorganic fillers are used for the ceramic powder, iron powder, stone powder, etc. Different materials may be mixed.

그러나 이러한 재료의 사용에도 불구하고 고무재료 자체가 연하기 때문에 도로면과 마찰시 지지능력이 크게 향상되지 않고 고무자체가 마찰면적이 넓어져 빙상에서 미끄럼성이 크게 되는 경향이 있으며 발포고무의 경우는 고무자체의 약함 때문에 큰 효과가 없다. 따라서 주로 겨울이 많은 지역에서는 체인과 스파이크 타이어를 사용할 수 밖에 없다.However, despite the use of these materials, the rubber material itself is soft, so the ability to support friction with the road surface does not significantly improve, and the rubber itself tends to have a large friction area, resulting in greater sliding on ice. Because of the weak rubber itself, it does not have a great effect. Therefore, chains and spike tires have to be used mainly in the winter season.

최근에는 고무의 경화특성을 이용하여 낮은 온도에서는 경화되고 상온에서는 고무특성을 갖는 고무핀을 이용하기도 하나, 이 경우는 고무핀의 머리부분이 닳아 없어질 경우 그 효과가 많이 반감되고, 또한 매우 많은 수의 고무핀을 사용해야 하며 그 제조과정도 복잡한 문제점이 있다.Recently, the rubber pins are hardened at low temperatures by using the hardening properties of rubber and rubber pins having rubber properties at room temperature. However, in this case, the effect is halved when the head of the rubber pins is worn out. There must be a number of rubber pins and the manufacturing process has a complicated problem.

본 발명은 상기와 같은 종래의 문제점들을 해결하기 위하여 안출된 것으로서 본 발명의 목적은 빙상 및 설상에서의 제동력 및 구동력이 우수한 겨울용 스터드레스 타이어를 제공하는데 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a winter studless tire having excellent braking force and driving force on ice and snow.

상기와 같은 목적을 달성하기 위한 본 발명에 따른 스터드레스 타이어의 트레드부(제2도)는, 종래의 겨울용 타이어의 트레드부(제1도)가 한 종류의 고무조성물로 이루어진 것과는 달리 성분이 서로 다른 고무조성물로 이루어진 표면층, 중간층 및 내층의 3중 구조로 형성되어 있으며, 표면층인 제1층(3)은 지면에 닿는 부위로서 전체트레드 두께의 1/5을 이루고, 중간 지지층인 제2층(4)은 트레드 두께의 3/5을 이루며, 내층인 제3층(5)은 벨트층(1) 바로 위에 위치하며 트레드 두께의 1/5을 이루도록 구성되어 있음을 특징으로 한다.The tread portion (FIG. 2) of the studless tire according to the present invention for achieving the above object is different from each other, unlike the tread portion (FIG. 1) of a conventional winter tire made of one kind of rubber composition. It is formed of a triple structure of the surface layer, the middle layer and the inner layer made of another rubber composition, and the first layer (3), which is the surface layer, reaches 1/5 of the total thickness of the tread as a part touching the ground, and the second layer (the middle supporting layer) 4) is 3/5 of the thickness of the tread, the inner layer is characterized in that the third layer (5) is located directly above the belt layer (1) and configured to achieve 1/5 of the tread thickness.

또한, 종래의 겨울용 타이어의 트레드 블럭은 가로, 세로 4~5cm인 것에 반하여, 본 발명에 따른 스터드레스 타이어의 패턴은 가로, 세로 각 0.5~3cm 정도의 크기가 다소 작은 트레드 블럭이 많은 수로 포함되도록 설계되어 있음을 특징으로 한다.In addition, while the tread block of the conventional winter tire is 4 to 5 cm in width and length, the pattern of the studless tire according to the present invention includes a large number of tread blocks having a smaller size of about 0.5 to 3 cm in width and length. It is characterized by the fact that it is designed.

본 발명에서 트레드부의 표면층에 해당하는 제1층의 고무조성물의 배합은 전체원료고무 100중량부로 기준했을 때 천연고무 80~60 중량부와 부타디엔고무 20~40 중량부로 하고, 이러한 원료고무 100 중량부에 대하여 무기충진제로서 입자크기가 약 100~500 미크론인 세라믹가루를 10~20중량부, 열경화성 레진(페놀알데하이드 레인)을 20~50 중량부, 카본블렉을 20~50중량부 사용하여 경도가 70~75 정도가 되도록 한다.In the present invention, the rubber composition of the first layer corresponding to the surface layer of the tread part is 80 to 60 parts by weight of natural rubber and 20 to 40 parts by weight of butadiene rubber based on 100 parts by weight of the total raw material rubber, and 100 parts by weight of such raw rubber 10 to 20 parts by weight of ceramic powder having a particle size of about 100 to 500 microns, 20 to 50 parts by weight of thermosetting resin (phenolaldehyde lane), and 20 to 50 parts by weight of carbon block are used as the inorganic filler. Make it about ~ 75.

중간층인 제2층은 블럭의 유동과 접촉면 증가를 위해 매우 무르고 저온특성이 우수한 고무층으로 이루어지는 데, 부타디엔고무 100중량부, 카본블렉 30~60중량부를 사용하여 경도가 40~50이 되도록 한다.The second layer, which is an intermediate layer, is made of a rubber layer which is very soft and has excellent low temperature properties for increasing the flow of the block and the contact surface, and the hardness is 40 to 50 using 100 parts by weight of butadiene rubber and 30 to 60 parts by weight of carbon blocks.

내층인 제3층은 언더트레드와 같은 역할을 하도록 천연고무 40중량부, 부타디엔고무 60중량부를 사용하고, 카본블렉을 40~60 중량부 사용하여 경도가 50~60이 되도록 한다.The third layer, which is an inner layer, uses 40 parts by weight of natural rubber and 60 parts by weight of butadiene rubber to serve as an undertread, and 40 to 60 parts by weight of carbon black to have a hardness of 50 to 60.

본 발명에 따른 스터드레스 타이어의 트레드 블럭은 가로·세로 각 0.5~3cm의 크기로서 트레드 블럭의 부피비율이 75~80% 가 되도록 조밀하게 설계되어 있다. 그리고, 그 루브의 폭은 0.5~1cm 간격을 유지한다.The tread block of the studless tire according to the present invention is densely designed so that the volume ratio of the tread block is 0.5 to 3 cm in width and length, respectively. And, the width of the grooves are kept 0.5 to 1cm apart.

이하, 참고예 및 실시예를 통하여 본 발명을 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to examples and examples.
