[발명이 속하는 기술분야 및 그 분야의 종래기술][Technical field to which the invention belongs and the prior art in that field]
본 발명은 백테 타이어의 사이드 월 고무조성물에 관한 것으로, 좀더 상세하게는 구두굽이나 구두의 바닥창에 사용되고 있는 루틸형 (Rutile type)의 이산화티타늄 (Titanium Dioxide)을 사이드 월(side wall) 컴파운드에 적용하여 외관을 개선시킨 백테 타이어의 사이드 월 고무조성물에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sidewall rubber composition of a back frame tire, and more particularly, to a side wall compound of rutile type titanium dioxide used in a shoe sole or an outsole of a shoe. The present invention relates to a sidewall rubber composition of a bag frame tire having improved appearance.
타이어는 미가류 배합고무와 섬유상 혼합제를 여러 가지 조합한 형상의 반제품으로 형성한 다음, 이를 성형공정에서 조립하고 135-170℃ 온도의 몰드내에서 일정시간 가류시키므로써 원하는 형상으로 가교반응시켜서 제조하는데, 사이드 월은 타이어의 옆부분으로 카카스를 보호하고 굴신운동을 하므로써 승차감을 좋게해 주는데, 우선 외관이 좋아야 한다.The tire is manufactured by forming a semi-finished product of various combinations of the unvulcanized rubber compound and the fibrous mixture, and then assembling it in a molding process and vulcanizing it in a mold at 135-170 ° C. for a certain time to crosslink the reaction to a desired shape. In addition, the sidewall protects the carcass by the side of the tire and improves the ride quality by exercising.
종래에는 백색 타이어 사이드 월 고무조성물의 백색도(brightness)를 좋게하기 위하여 현용(Anatase type)의 이산화티타늄을 사용해 왔으나, 현용의 이산화티타늄을 사용한 사이드 월 고무조성물은 자외선에 의한 노화, 외관 변색 및 고하중으로 인한 외관상 및 원가증가의 문제점이 있다.In the past, Anatase type titanium dioxide was used to improve the whiteness of the white tire sidewall rubber composition. However, the sidewall rubber composition using the titanium dioxide of the present type is aging due to ultraviolet rays, discoloration and high load. There is a problem of appearance and cost increase.
[발명이 이루고자 하는 기술적 과제][Technical problem to be achieved]
본 발명자들은 이러한 문제점을 해결하기 위한 연구를 수행하던 중, 기존의 현용 이산화티타늄을 구두굽이나 구두의 바닥창에 사용되고 있는 루틸형 이산화티타늄으로 대체하므로써, 상기의 문제점을 해결할 수 있음을 알아내고 본 발명을 완성하였다.The inventors have found out that the above problems can be solved by replacing existing existing titanium dioxide with rutile type titanium dioxide which is used for the sole of the shoe or the sole of the shoe during the research to solve the problem. The invention has been completed.
따라서, 본 발명의 목적은 기존의 현용 이산화티타늄을 적용한 사이드 월 고무조성물보다 백색도, 노화 및 황색화 저항성, 내마모성 등을 개선시킨 루틸형 이산화티타늄을 이용한 백색 타이어의 사이드 월 고무조성물을 제공함에 있다.Accordingly, it is an object of the present invention to provide a sidewall rubber composition of a white tire using rutile type titanium dioxide having improved whiteness, aging and yellowing resistance, abrasion resistance, and the like, compared to the existing sidewall rubber composition to which current titanium dioxide is applied.
즉, 본 발명은 원료고무, 보강제, 충진제, 가류활성제, 공정조제, 공정오일, 가황제 및 가류촉진제로 구성된 공지의 사이드 월 고무조성물에 30∼40 PHR의 루틸형 이산화티타늄을 함유하는 백색 타이어의 사이드 월 고무조성물 임을 특징으로 한다.That is, the present invention relates to a white tire containing 30-40 PHR of rutile titanium dioxide in a known sidewall rubber composition composed of raw rubber, reinforcing agent, filler, vulcanizing agent, process aid, process oil, vulcanizing agent and vulcanization accelerator. It is characterized in that the sidewall rubber composition.
[발명의 구성][Configuration of Invention]
자동차용 타이어의 요구성능은 사용용도에 따라서 크게 다르며, 타이어의 각가가의 부위에 따라서도 요구성능이 크게 달라지게 된다. 노면과 타이어가 접촉하는 트레드 고무조성물은 내마모성, 내 컷앤칩성, 내발열성 및 저연비 성능이 요구되며, 사이드 월 부위는 내노화성, 내황색화성, 내피로성, 내오존성이 요구된다. 특히, 백테 타이어의 사이드 월은 선명한 백색도를 요구하고 있다.The required performance of automobile tires varies greatly depending on the intended use, and the required performance varies greatly depending on the parts of the tires. The tread rubber composition in contact with the road surface is required to have abrasion resistance, cut and chip resistance, heat resistance and low fuel consumption performance, and side wall parts are required for aging resistance, yellowing resistance, fatigue resistance, and ozone resistance. In particular, the sidewalls of the back frame tires require clear whiteness.
본 발명은 기존의 백색 사이드 월 부위의 백색도를 증가시키며 자외선에 의한 황색화 정도를 감소시킬 뿐만 아니라, 사이드 월 고무조성물의 노화를 감소시킬 수 잇는 백테 타이어의 사이드 월 고무조성물에 관한 것이다.The present invention relates to a sidewall rubber composition of a back frame tire that can increase the whiteness of the existing white sidewall portion and reduce the yellowing degree by ultraviolet rays, as well as reduce the aging of the sidewall rubber composition.
본 발명에 의한 사이드 월 고무조성물은 원료고무로 SMR, 보강제 및 충진제로 하드 클레이(Hard Clay), 가류활성제로 스테아린산 및 산화아연, 공정조제, 공정오일, 가류촉진제, 가황제로 구성된 고무조성물에 루틸형 이산화티타늄을 30∼40 PHR 변량 첨가하여 시험한 결과, 기존의 현용 이산화티타늄을 사용한 사이드 월 고무조성물에 비하여 백색도, 황색도, 저항선 및 내마모성이 향상되었다. 이러한 효과는 본 발명에 사용한 루틸형 이산화티타늄의 굴절율은 2.73으로서 종래의 현용 루틸형 이산화티타늄의 굴절율 2.55보다 더 높은 물리적 특성에 기인한다.The sidewall rubber composition according to the present invention is a rutile type rubber composition composed of SMR as a raw material rubber, a hard clay as a reinforcing agent and a filler, a stearic acid and zinc oxide as a vulcanizing agent, a process aid, a process oil, a vulcanization accelerator, and a vulcanizing agent. As a result of 30 to 40 PHR variable titanium dioxide test, the whiteness, yellowness, resistance line and abrasion resistance were improved compared to the conventional sidewall rubber composition using titanium dioxide. This effect is due to the physical property of the refractive index of the rutile titanium dioxide used in the present invention is 2.73, which is higher than the refractive index of 2.55 of the conventional rutile titanium dioxide.
