Description

자동차 타이어용 실란트 조성물{SEALANT COMPOSITION FOR CAR TIRE}Sealant composition for automobile tire {SEALANT COMPOSITION FOR CAR TIRE}

본 발명은 자동차 타이어용 실란트 조성물에 관한 것으로, 더욱 상세하게는 밀봉제, 동결방지제, 점착제, 고형분 및 탈이온수를 포함하여 이루어지는 자동차 타이어용 실란트 조성물에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealant composition for automobile tires, and more particularly, to a sealant composition for automobile tires comprising a sealant, an antifreeze agent, an adhesive, a solid content, and deionized water.

본 발명은 펑크난 타이어를 봉함하는 조성물에 관한 것으로, 보통의 경우 튜브레스 타이어(Tubeless)는 못이나 쐐기 등의 이물에 찔려도 이물질이 쉽게 빠지지 않기 때문에 급격한 공기압의 저하가 발생하지 않아 비교적 안전한 것으로 여겨지고 있으나, 이물에 찔린 상태로 고속 주행시에는 타이어 자체가 매우 동적인 상태로 전환되어 이물이 쉽게 빠져나가게 되므로 공기압의 급격한 저하가 야기되고 차량은 균형을 잃어 운전자는 위험한 상태에 놓이게 된다.The present invention relates to a composition for sealing flat tires, and in general, tubeless tires are relatively safe because they do not easily fall out due to foreign matters being easily caught by foreign substances such as nails or wedges. Although it is considered, when the vehicle is stuck in a high speed, the tire itself is converted into a very dynamic state, and the foreign material is easily pulled out, which causes a sudden drop in air pressure and the vehicle loses balance and the driver is in a dangerous state.

따라서 타이어 제조업계에서는 이러한 타이어의 펑크를 없애거나 감소시키기 위해 타이어의 인너라이너 내면 및 외면에 봉함용 조성물을 일정한 두께로 도포하거나, 성형 또는 스프레이 하는 공정을 통해 이물에 의한 펑크 발생시 펑크부위의 즉각적으로 자체 봉함되어 내부공기의 누출을 방지하도록 하여 차량의 안전운행에 기여하려는 기술의 개발을 계속 시도하고 있다.Therefore, in the tire manufacturing industry, in order to remove or reduce the puncture of the tire, the puncture portion is immediately applied when the puncture caused by foreign matter is applied to the inner and outer surfaces of the tire by applying a sealing composition to a certain thickness, or forming or spraying the coating. The company continues to develop technologies to contribute to the safe operation of vehicles by sealing them to prevent leakage of internal air.

종래에 개발된 타이어 봉함용 조성물은 저분자량인 액상 엘라스토머와 고분자량인 고상 엘라스토머를 단순히 브랜드하여 제조된 것이 주로 사용되었는데, 이러한 종래에 타이어 봉함용 조성물은 주행중 타이어가 동적인 상태에 놓여지게 되면 혼합되어 있는 저분자량의 엘라스토머는 점도가 떨어지기 때문에 원심력에 의해 중앙부위로 이동하게 되고 봉함용 조성물이 이동한 부위에 못과 같은 이물이 찔리게 되면 봉함효과가 나타나지 않는 단점이 있으며, 이러한 문제점을 해결하기 위해 고분자량의 엘라스토머의 양을 추가할 경우에는 조성물의 상 분리 현상은 해소할 수 있으나 봉함용 조성물이 쉽게 경화되어 봉함효과를 상실하는 문제점이 있었다.The tire sealing composition developed in the related art was mainly manufactured by simply branding a low molecular weight liquid elastomer and a high molecular weight solid elastomer. Such a tire sealing composition is mixed when the tire is placed in a dynamic state while driving. The low molecular weight elastomer has a disadvantage in that its viscosity decreases, so it moves to the central part by centrifugal force, and foreign matters such as nails are stuck on the moving parts of the sealing composition. When the amount of the high molecular weight elastomer is added, the phase separation phenomenon of the composition can be solved, but there is a problem in that the sealing composition is easily cured and loses the sealing effect.

전술한 밀봉제는 20 내지 60 중량부가 첨가되며, 수성라텍스를 포함하여 이루어지는데, 전술한 수성라텍스는 주로 고무성분으로 이루어져 있기 때문에 타이어를 구성하는 물질과 상당한 유사성이 있어 실란트 조성물이 타이어 내부에서 밀봉효과를 유지하도록 하는 역할을 한다.The above-mentioned sealant is added 20 to 60 parts by weight, and includes an aqueous latex. The above-described aqueous latex is mainly composed of a rubber component, so that the sealant composition is sealed in the tire because the sealant composition is substantially similar to the tire constituent material. It plays a role in maintaining the effect.

전술한 동결방지제는 20 내지 40 중량부가 첨가되며, 프로필렌글리콜, 에틸렌글리콜, 디에틸렌글리콜 및 부틸렌글리콜로 이루어진 그룹으로부터 선택된 하나 이상을 포함하여 이루어지는데, 이러한 동결방지제는 겨울철 영하에 온도에서도 실란트 조성물이 동결되지 않도록 하여 사용가능한 온도의 범위를 넓혀주는 역할을 한다.The aforementioned cryoprotectant is added 20 to 40 parts by weight, and comprises at least one selected from the group consisting of propylene glycol, ethylene glycol, diethylene glycol and butylene glycol, wherein the cryoprotectant is a sealant composition even at temperatures below freezing in winter.

전술한 성분들로 이루어진 자동차 타이어용 실란트 조성물을 제조하는 방법은 일정한 용량의 비이커에 전술한 함량비의 혼합물을 넣어 밀봉하고 상온에서 12시간 동안 혼합하여 제조하게 된다.The method for producing a sealant composition for automobile tires composed of the above-mentioned components is prepared by sealing a mixture of the above-described content ratios in a beaker of a constant capacity and mixing at room temperature for 12 hours.

전술한 방법을 통해 제조된 자동차 타이어용 실란트 조성물은 대기중에 공기와 접하며 굳어지는 성질이 있기 때문에 제조과정이 완료된 후에는 사용하기 전까지 밀봉용기에 넣어 보관하게 된다.Since the sealant composition for automobile tires manufactured by the above-described method is in contact with air in the air and hardens, it is stored in a sealed container until use after the manufacturing process is completed.

전술한 과정으로 제조된 자동차 타이어용 실란트 조성물을 테스트하는 방법은 드릴을 이용하여 타이어에 임의적으로 구멍을 내고, 손상부위에 비눗물을 분사하여 공기압 누출 확인 및 손상부위를 표시해 놓는다.In the method for testing a sealant composition for automobile tires manufactured by the above-described process, a hole is arbitrarily drilled into the tire using a drill, and soapy water is sprayed on the damaged part to check for air pressure leakage and to mark the damaged part.

다음으로 콤푸레셔를 결합하고 실란트 조성물 180 내지 200 밀리리터와 공기압을 타이어 내부에 동시에 주입하고 비눗물을 구멍난 부위에 분사하여 공기압 누출 여부를 확인하게 된다.Next, the compressor is combined and 180 to 200 milliliters of the sealant composition and air pressure are simultaneously injected into the tire, and soapy water is injected into the hole to check whether the air pressure leaks.

타이어 공기압의 85%(65PSI) 까지 공기를 주입하고, 공기를 주입한 타이어를 자동차에 적용하여 저속으로 2킬로미터를 주행한 후에 비눗물을 구멍난 부위에 분사하여 공기압 누출을 확인하고, 타이어 공기압 측정기를 이용하여 타이어 내부에 공기압에 변화량을 측정한다.Inject air up to 85% (65PSI) of tire pressure, apply air-inflated tires to the car, drive 2 kilometers at low speed, and spray soapy water on the hole to check for air pressure leaks. Measure the change in air pressure inside the tire.

전술한 과정 이후에 2시간 간격으로 3차례에 걸쳐 타이어 공기압을 측정하여 밀봉상태를 확인한다.After the above-described process, the tire air pressure is measured three times at intervals of two hours to check the sealing state.
