Description

주황색 싸이드월 고무조성물Orange Sidewall Rubber Composition

본 발명은 변색이 덜되거나 느리고 장식효과도 얻을 수 있고 동적 내오존성, 내피로균열성 및 접착성을 향상시킨 주황색 싸이드월 고무조성물에 관한 것이다.The present invention relates to an orange sidewall rubber composition having less discoloration or slowness and a decorative effect and improving dynamic ozone resistance, fatigue crack resistance and adhesion.

싸이드월은 타이어의 측면을 보호하는 것이 주목적이나 규격, 제품명, 상표명 등의 표시가 있어 외관상 더러움이 적은 것이 바람직하다. 그러나 오늘날에는 장식적인 효과를 얻기 위한 목적으로 백색 싸이드월을 사용하는 경우가 많아지고 있으나 사용 환경에 따른 영향, 즉 오존, 자외선, 오염물질 등으로 변색이 되고 타이어의 노화방지를 위해 사용한 오염성 노화방지제나 오염성 오일에 의해서도 변색이 되어 오히려 외관상 더러워 보이는 경우가 흔히 있다.The side wall is mainly intended to protect the side of the tire, but it is preferable that there is little dirt in appearance since there are indications such as specifications, product names, and brand names. Today, however, the use of white sidewalls for the purpose of achieving decorative effects is increasing. However, the effects of the environment, such as ozone, ultraviolet rays, pollutants, etc., discoloring and preventing the aging of tires. Often discolored by detergents or contaminated oils, they appear rather dirty.

따라서 본 발명은 변색이 덜 되고 장식적인 효과도 얻을 수 있을 뿐만 아니라 동적 내오존성, 내피로균열성 그리고 접착성을 향상시킨 주황색 싸이드월 고무조성물을 제공코져하는 것이다.Therefore, the present invention is to provide a orange sidewall rubber composition which is less discoloration and can obtain a decorative effect as well as improved dynamic ozone resistance, fatigue crack resistance and adhesion.

고무용 안료(착색제)는 무기, 유기계로 나눌 수 있으며 색깔에 따라 백색안료, 흑색안료, 황색안료, 적색안료, 청색안료, 녹색안료, 금속안료 등이 있다. 따라서, 이러한 안료를 적절히 사용함으로써 제품의 색깔을 마음대로 조절할 수 있다. 그러나 현재 타이어에는 대부분 백색 싸이드월 만이 사용되고 있으며 이 싸이드월의 고무조성물은 부틸고무, 천연고무, 이피디엠에 티타늄디옥사이드, 클레이, 왁스, 노화방지제, 스테아린산, 점착제, 공정오일, 아연화, 가류제, 촉진제 등으로 구성되어 있다.Rubber pigments (colorants) can be divided into inorganic and organic, depending on the color, there are white pigments, black pigments, yellow pigments, red pigments, blue pigments, green pigments, metal pigments. Therefore, the color of a product can be adjusted arbitrarily by using such a pigment suitably. However, only white sidewalls are currently used in tires, and the rubber composition of these sidewalls is butyl rubber, natural rubber, EPDM, titanium dioxide, clay, wax, anti-aging agent, stearic acid, adhesive, process oil, zincation, vulcanizing agent, accelerator. And the like.

주황색을 나타내기 위한 안료로는 황연, 카드늄 옐로우, 한사 옐로우, 디스아조계 안료 등이 있으나 황연은 고무를 가황할때 검은색으로 변화함으로 사용할 수 없으며 카드늄 옐로우는 독성이 있으며 한사 옐로우는 브리딩(Bleeding)성과 브루밍(Blooming)성이 있어 사용에 제약을 받는다. 디스아조계 안료는 구조에 따라 청색에서 적색까지 나타낼 수 있으나 본 발명에서는 다음과 같은 구조식을 갖는 디아니시딘 오렌지(Dianisidine orange, o-dianisidine과 acetoacetanilide의 결합체)를 이용한 주황색 싸이드월 고무조성물에 대한 것이다.Pigments to represent orange include sulfur lead, cadmium yellow, Hansa yellow, and disazo pigments, but sulfur lead cannot be used as it turns black when vulcanizing rubber. Cadmium yellow is toxic and Hansa yellow is bridding. ) And blooming (Blooming) is restricted in use. The disazo pigment may be represented from blue to red depending on the structure, but the present invention relates to an orange sidewall rubber composition using dianisidine orange (a combination of o-dianisidine and acetoacetanilide) having the following structural formula. .

싸이드월은 내오존성, 내변색성, 비오염성, 자외선 저항성, 우수한 접착성 등의 요구 특성을 나타낼 수 있어야 하므로 본 발명에서는 내오존성, 비오염성, 내변색성을 향상시키고자 클로로부틸고무 5-50PHR, 이피디엠고무 5-30PHR, 천연고무 10-50PHR를 사용하였으며, 특히 동적 내오존성과 내피로균열성을 높이기 위하여 클로로부틸고무와 디아니시딘 오렌지(Dianisidine orange; o-dianisidine과 acetoacetanilide의 결합체)50-100PHR를 이용한 주황색 싸이드월 고무조성물을 제공코저 하는 것이다.Since the sidewall should be able to exhibit the required characteristics such as ozone resistance, discoloration resistance, non-pollution resistance, UV resistance, and excellent adhesion, in the present invention, to improve ozone resistance, non-pollution resistance, and discoloration resistance, chlorobutyl rubber 5-50PHR , IPIDM rubber 5-30PHR, natural rubber 10-50PHR, especially chlorobutyl rubber and dianisidine orange (combination of o-dianisidine and acetoacetanilide) to improve the dynamic ozone resistance and fatigue crack resistance It is to provide orange sidewall rubber composition using -100PHR.

여기에서 노화방지를 위하여 비오염성 노화방지제인 2,6-디 터시아리 부틸 파라 크레졸(2,6-di-tert-butyl-p-cresol)과 탄화수소계 파라핀 왁스(Hydrocarbon paraffine wax; 중간 내지 저분자량)를 적용하였다.Here, 2,6-di-tertary butyl para cresol (2,6-di-tert-butyl-p-cresol) and hydrocarbon-based paraffin wax (medium to low molecular weight), which are non-polluting anti-aging agents, are used to prevent aging. ) Was applied.

공정오일은 비오염성인 파라핀 오일을 이용하였으며 가류제로는 스테아린산, 아연화, 불용성황 (오일함향 20%), 알킬 페놀 디설파이드(유황함량 21%) 1-5PHR를 사용하였고 촉진제로는 N,N-디페닐 구아니딘(N,N-diphenyl guanidine), N-옥시 디에틸렌-2-벤조티아질 설펜아마이드(N-oxy didthylene-w-benzothiazyl sulfenamide)를 사용하였다. 여기에 접착성을 부여하기 위하여 소량의 페놀 포름알데히드 레진 1-3PHR을 사용하였다.Non-polluting paraffin oil was used as a process oil. Stearic acid, zincation, insoluble sulfur (oil content of 20%), alkyl phenol disulfide (21% sulfur content) 1-5PHR were used as a vulcanizing agent, and N, N-di as an accelerator. Phenyl guanidine (N, N-diphenyl guanidine), and N-oxy diethylene-2-benzothiazyl sulfenamide (N-oxy didthylene-w-benzothiazyl sulfenamide) were used. A small amount of phenol formaldehyde resin 1-3PHR was used to impart adhesion thereto.

표 1에 나타낸 바와 같은 고무배합표에 의해 만들어진 싸이드월 고무조성물을 160℃로 20분간 가류시킨 결과 동적 내오존성과 내피로균열성이 뛰어난 주황색 싸이드월을 얻을 수 있었다.The sidewall rubber composition produced by the rubber compounding table as shown in Table 1 was quenched at 160 ° C. for 20 minutes to obtain an orange sidewall having excellent dynamic ozone resistance and fatigue cracking resistance.
