본 발명은 타이어 트레드 부위에 임의의 배열밀도를 가진 단섬유를 임의로 배열하므로서 트레드의 탄성률을 향상시키고 마찰저항 및 빙상의 미끄럼저항을 항상시키기 위한 것으로서 특히 트레드 부위가 마모시에 단섬유가 외부로 노출하여 노면에 직접 접촉되게 하여 스파이크 효과를 발휘토록 하기 위하여 타이어의 가압가류시에 트레드 부위에 단섬유를 배열하여 압력에 의해 고무에 단섬유질이 혼입되게 하는 방법을 제공하는 것이 본 발명의 목적이다.The present invention is to improve the elastic modulus of the tread and to always keep the frictional resistance and the sliding resistance of the ice sheet by arranging the short fibers having a random arrangement density on the tire tread part, especially when the tread part is exposed to the outside when the tread part wears It is an object of the present invention to provide a method in which short fibers are incorporated into rubber by pressure by arranging short fibers in a tread part during pressurized curing of a tire so as to directly contact the road surface to exert a spike effect.
종래 동절기용 타이어는 빙설노면에서의 미끄럼저항을 증가시키기 위하여 트레드 고무에 이물질을 혼입하여 미끄럼저항을 개선해왔으나 혼입 물질인 섬유질, 금속, 모래, 금강사 등을 다량으로 혼입하여 내마모성이 떨어지는 문제점이 있었다.Conventional winter tires have improved the sliding resistance by incorporating foreign matter in the tread rubber to increase the sliding resistance on the ice snow surface, but there is a problem in that the wear resistance by incorporating a large amount of mixed materials such as fiber, metal, sand, gold steel yarn.
또한 트레드 고무에 규칙적으로 섬유질을 혼입하는 종래의 혼입 방법은 혼입물질을 트레드 고무 배합물의 배합공정에서 첨가하여 압출기에서 압출하게 되므로 섬유등 혼합물은 방향성을 갖게 되는데 이와 같이 혼입물질이 방향성을 가짐으로서 고무의 탄성률이 크게 증가하지만 배향방향과 다른 방향에서는 탄성률이 불량한 결점이 있기 때문에 이 방향성을 무방향성으로 하려는 시도가 있으나 현재에는 정확히 이루어지지 않고 있다.In addition, in the conventional mixing method of regularly incorporating fiber into the tread rubber, the mixed material is added in the blending process of the tread rubber compound and extruded in the extruder, so that the mixture such as fibers has a directionality. Although the modulus of elasticity increases greatly, there is a defect in the elastic modulus which is poor in a direction different from the orientation direction, an attempt has been made to make this orientation non-directional, but it is not made precisely at present.
이러한 이유로 섬유나 기타 혼입물의 배향을 무방향성으로 해야 탄성률이 증가하는데 이때는 여러 방향으로 배향한 고무를 적층해야 하는 문제점이 있다.For this reason, the elastic modulus increases when the orientation of fibers or other admixtures is non-directional, and there is a problem in that rubbers oriented in various directions must be laminated.
또 상기한 방법으로 타이어를 제조하게 되면 타이어의 중량이 많아지고 기타 성능에도 악영향을 미치므로 이 방법은 가치가 없는 것으로 알려져 있다.In addition, when the tire is manufactured by the above method, the weight of the tire is increased and other performances are adversely affected, so this method is known to be of no value.
이상과 같은 종래의 트레드의 결점을 개선하기 위하여, 본 발명은 트레드 고무에 단섬유질을 혼입하는 방법을 개선함으로써 단섬유의 방향성을 없애고자 한 것이다.In order to improve the drawbacks of the conventional tread as described above, the present invention is to eliminate the direction of the short fibers by improving the method of incorporating the short fibers in the tread rubber.
트레드 고무 배합시에 혼입물질을 첨가하는 현재의 과정을 생략하고 성형에 의하여 만들어진 그린케이스(C)위에 단섬유(B)를 보통의 천 정도의 두께로 감고, 그 단섬유가 감긴 상태의 그린케이스를 가류기(A)에 넣어 가류 함을 특징으로 한 것으로서, 이와 같은 방법으로 가류하게 되면 고온에 의해 고무는 몰드 형상에 따라 녹아 들어가게 되고, 단섬유는 제2도에서 나타낸 바와 같은 형태로 트레드 바로 밑으로 스며들어 층을 이루면서 그루브 부위에서는 조밀한 분포를 갖고, 블록에서는 압력이 낮아지므로 상대적으로 단섬유의 밀도가 낮은 분포로 된다.By omitting the current process of adding the mixed material in the tread rubber compounding, the short fiber (B) is wound on the green case (C) made by molding to a thickness of about a thousand cloth, and the green fiber in the state of the short fiber is wound. It is characterized in that the vulcanizer in the vulcanizer (A), and when vulcanized in this way, the rubber melts according to the mold shape due to the high temperature, and the short fibers have a tread bar in the form as shown in FIG. As it penetrates to form a layer, it has a dense distribution in the groove area and a low pressure in the block, resulting in a relatively low density of short fibers.
또한 이 방법에서는 압출시에 발생되는 방향성이 없어지기 때문에 고무의 탄성률이 모든 부위에서 같고, 노면을 주행시 구동성이나 조종성 및 제동성능을 향상시킴과 동시에 빙설노면에서의 접지 능력도 향상시킨다.In addition, in this method, since the direction generated during extrusion is lost, the elastic modulus of the rubber is the same in all parts, and the driving performance, the maneuverability and the braking performance when driving the road surface are improved, and the grounding ability on the ice snow road is also improved.
또한 현재 섬유질 타이어의 조기 마모의 문제점을 해소하여 내마모 성능을 향상시키면서 트레드 고무의 탄성률이 높아져서 마찰 저항성이 향상되므로써 빙설노면에서의 타이어 성능을 향상시킬 수 있는 장점이 있다.In addition, the current problem of early wear of the fibrous tire to improve the wear resistance, while improving the elastic modulus of the tread rubber has the advantage of improving the tire performance on the ice snow road surface by improving the frictional resistance.
본 발명은 성형공정에 의해 제조된 그린케이스에 단섬유만 감아주는 공정만 추가 될 뿐이므로 제조공정이 간단하면서 성능을 향상시킬 수 있는 장점이 있다.The present invention has the advantage that the manufacturing process is simple and the performance can be improved since only the process of winding only short fibers is added to the green case manufactured by the molding process.
이상과 같은 본 발명 방법에 의한 타이어 트레드는, 단섬유의 방향성을 무방향성으로 하여 트레드 고무의 탄성을 높여 타이어의 성능을 향상시키며, 제조시 그린 케이스에 단섬유를 감아주고 가류시에는 단섬유가 트레드 고무를 가류하게 되므로 공정이 간단하고 단섬유의 방향을 임의로 할 수 있게 된다. 또한, 트레드 부위의 마모가 진행됨에 따라 섬유층이 표층으로 노출되어 빗길, 눈길에서의 제동력과 가속성능 및 내마모성을 향상시키게 되고 그루브 부위에 형성되는 고밀도의 단섬유는 이 부위를 보강하므로서 크랙을 방지한다.As described above, the tire tread according to the present invention improves tire performance by increasing the elasticity of the tread rubber by making the directionality of the short fibers non-directional, and winding the short fibers in a green case during manufacture and short fibers during vulcanization. Since the tread rubber is vulcanized, the process is simple and the direction of the short fibers can be arbitrarily selected. In addition, as the wear of the tread site progresses, the fiber layer is exposed to the surface layer, thereby improving braking force, acceleration performance, and abrasion resistance at rain, snow, and high density short fibers formed in the groove area reinforce the site to prevent cracking. .
