Description

자동차 유리세정제Automotive glass cleaner

본 발명은 자동차 유리세정제에 관한 것으로서, 더욱 상세하게는 고비점 고급알콜과 양이온성 계면활성제가 함유되어 있어 동절기 성애제거능을 부여함은 물론이고 발수능을 부여하고 있어 하절기 폭우로 인한 물필름 형성을 방지하므로써 차창 시야를 맑게하여 안전운전에 기여하게 되는 자동차 유리세정제에 관한 것이다.The present invention relates to a glass cleaner for automobiles, and more specifically, high boiling point alcohol and cationic surfactants are contained to provide winter defrosting ability as well as water repellency to form water film due to heavy rains in summer. The present invention relates to a glass cleaner for automobiles, which contributes to safe driving by clearing the window view.

유리는 통기성이나 흡수성을 전혀 갖지 않고 빛의 투과성만을 갖는 치밀한 구조의 비결정성 고체로서 그 표면은 내부와 달리 성형도중 휘발성 물질의 휘산과 보관중의 풍화 및 침식에 의해 나트륨과 붕소 등의 농도가 떨어지고 이산화규산층이 생겨 알칼리에 의해 이산화규소가 파괴되고 유리표면의 일부가 떨어져 나감으로써 침식이 반복되거나 물을 함유한 규산층에서 물이 건조되면 미세한 균열이 발생하기도하여 미세한 다공질 구조로 변하게 된다. 이로인해 유리의 표면층에는 대기중의 먼지입자, 매연, 유지류등이 손쉽게 흡착, 확산 및 침투되어 오염막을 형성하게 되며, 시간이 지남에 따라 유리표면이 치밀함은 상실되어 물이나 천을 이용하여 닦아도 쉽게 제거되지 않는 두터운 오염막을 이루게 된다.Glass is a non-crystalline solid that has no air permeability or absorbency but only light transmittance, and its surface has a low concentration of sodium and boron due to volatilization of volatile substances during molding and weathering and erosion during storage. Silica dioxide layer is formed and silicon dioxide is destroyed by alkali and part of the glass surface is dropped, so that erosion is repeated or water is dried in the silicic acid layer containing water. As a result, the surface layer of glass easily adsorbs, diffuses, and penetrates into the air to form a contaminated film. As time passes, the surface of the glass is lost, and the surface of the glass is lost. It forms a thick fouling film that cannot be removed.

특히 자동차 창유리의 경우는 대기중의 오염외에 자동차용 왁스 등의 원료로 사용되는 유지, 실리콘오일, 수지류 등이 흡착되어 강우시나 야간주행시에 구름막을 형성하거나 빛을 굴절시켜 시계를 차단함으로써 사고를 유발할 수 있다.Especially in the case of automobile window glass, fats, silicone oil, resins, etc., which are used as raw materials for automobile wax, are adsorbed in addition to the air pollution, so that during rain or night driving, it forms a cloud film or refracts the light to block the clock. May cause

따라서, 종래에는 유리세정제를 유리면에 접착된 먼지, 얼룩 등의 오염을 제거하는 것을 주목적으로 하고, 겨울철이나 장마철에 자동차 유리의 내·외의 온도차이에 의해 형성되는 김서림 방지효과에 대한 특별한 대책이 없어 유리세정후의 시계확보의 어려움을 안고 있었다.Therefore, conventionally, a glass cleaner is mainly used to remove dirts, stains, etc. adhered to the glass surface, and there is no special countermeasure against the anti-fog effect formed by the temperature difference between the inside and outside of the automobile glass in winter or rainy season. He had difficulty securing the clock after glass cleaning.

또한, 우리나라 공업규격에 따른 자동차 유리세정제는 빙결점, 금속부식성, 투명도, 색상 등에만 국한되어 있고, 현재 유통되고 있는 대부분의 유리세정제가 획일적으로 공업규격에만 충실해 왔다.In addition, the automotive glass cleaner according to the industrial standard of Korea is limited only to the freezing point, metal corrosion, transparency, color, etc., and most of the glass cleaners currently in circulation have been faithful to the industrial standard.

현재 국내에서 유통되고 있는 일부 유리세정제가 통상물에 메틸알콜을 22 ~ 25 중량% 함유시켜 빙결점을 -20℃ 이하로 강하시키나, 28 ~ 32 중량% 함유시켜 빙결점을 -25℃ 이하로 강하시키거나, 또는 메틸알콜을 전혀 함유시키지 않고 봄, 여름, 가을용으로 사용하고 있다. 또한, 여기에 소량의 계면활성제(0.05 ~ 0.10 중량%)를 첨가하여 세정력을 부여하였고, 필요에 따라 소량의 금속부식방지제를 첨가하여 창유리 주변의 금속에 발생될 수도 있는 부식을 방지하였다.Some glass cleaners currently distributed in Korea contain 22 to 25% by weight of methyl alcohol in ordinary products to lower the freezing point to -20 ℃ or lower, but 28 to 32% by weight to lower the freezing point to -25 ℃ or lower. It is used for spring, summer and fall without any methyl alcohol. In addition, a small amount of surfactant (0.05 ~ 0.10% by weight) was added thereto to impart cleaning power, and if necessary, a small amount of metal corrosion inhibitor was added to prevent corrosion that may occur on the metal around the window glass.

그러나, 상기에서 설명한 바와 같은 국내 공업규격에 따른 자동차 유리세정제는 단순히 빙점강하에만 전념한 나머지 세정제를 유리에 뿌리는 순간에는 창의 눈, 서리를 녹이지만 고휘발성의 메탄올이 순식간에 휘발하고 메탄올의 휘발에 의해 물이 즉시 얼어붙어서 창유리를 흐리게 하는 바, 시야장애를 없애려면 세정제를 지속적으로 뿌리주어야 하는 문제가 있다. 또한, 발수능이 전혀 고려되지 않아 하절기 폭우중의 빗물이 창유리에 젖어 흘러내림으로써 시야장애를 일으키는 또다른 문제가 있다.However, the automotive glass cleaner according to the domestic industrial standard as described above is devoted to simply dropping the freezing point and dissolves snow and frost at the moment of spraying the cleaner onto the glass. As the water freezes immediately and blurs the window glass, there is a problem in that the cleaning agent must be continuously sprayed to eliminate visual disturbances. In addition, the water repellency is not considered at all, there is another problem causing the visual field impaired by the rain water dripping down the window glass during heavy rain in summer.

종래의 자동차 유리세정제가 세정의 기본 기능만을 고려하고 일시적인 서림방지효과를 얻기 위해 강한 향취를 갖는 유기용제와 계면활성제를 사용하였는데 반하여, 본 발명에서는 고비점의 고급알콜을 함유시켜 동절기의 눈, 서리에 의해 생기는 성애를 제거하도록 하고, 또한 생분해능이 우수하면서도 발수능을 보유하고 있는 특정 양이온성 계면활성제를 함께 함유시켜 하절기 폭우에 의한 김서림을 방지하는 새로운 조성의 자동차 유리세정제를 제조함으로써 본 발명을 완성하였다.Conventional automotive glass cleaners use organic solvents and surfactants that have strong odors in order to consider only the basic functions of cleaning and to obtain temporary anti-fog effects. In the present invention, high-alcohol high-alcohol contains high-alcohol snow and frost. The present invention is completed by preparing a vehicle glass cleaner having a new composition which removes the frost caused by the stiffness and also prevents fog caused by heavy rain in summer by containing a specific cationic surfactant having excellent biodegradability and water repellency. It was.

따라서, 본 발명은 눈, 서리가 끼는 겨울이나, 여름의 폭우중에도 항상 시야를 맑게하여 안전운전에 기여하는 자동차 유리세정제를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide an automobile glass cleaner that contributes to safe driving by clearing the field of vision at all times during heavy rains such as winter and summer when snow and frost are present.

본 발명은 자동차 유리세정제에 있어서, 고비점의 고급알콜 5 ~ 20 중량%와 양이온성 계면활성제 0.2 ~ 0.5 중량%가 함유된 것을 그 특징으로 한다.The present invention is characterized in that the automotive glass cleaner contains 5 to 20% by weight of a high boiling point high alcohol and 0.2 to 0.5% by weight of a cationic surfactant.

이와 같은 본 발명을 더욱 상세히 설명하면 다음과 같다.Referring to the present invention in more detail as follows.

본 발명은 자동차 유리세정제에 고비점의 고급알콜과 양이온성 계면활성제를 함께 함유시켜 성애제거능 및 발수능을 동시에 보유토록하여 4계절내내 맑은 시야를 보장하여 안전운전에 기여하게 되는 자동차 유리세정제에 관한 것이다.The present invention relates to an automobile glass cleaner which contains high-alcohol and cationic surfactant having high boiling point in the automobile glass cleaner to simultaneously maintain the defrosting ability and water repellency, thereby ensuring a clear view in all four seasons, thereby contributing to safe driving. will be.

본 발명에서는 고비점의 고급알콜으로서 탄소원자수 3 ~ 10의 알콜을 사용한다. 저급알콜로 분류되는 메탄올이 빙점(어는점) -98℃와 비점(끓는점) 64.6℃를 갖는데 반하여 본 발명에서 사용되는 고급알콜은 빙점(어는점)이 높고 비점(끓는점)이 낮아 휘발속도가 느리게되므로 고급알콜은 눈, 서리를 용해한 물과 함께 고급알콜 수용액을 형성하므로써 재빙결되지 않는다.In the present invention, alcohol having 3 to 10 carbon atoms is used as a high boiling point alcohol. Methanol, which is classified as a lower alcohol, has a freezing point (freezing point) of -98 ° C and a boiling point (boiling point) of 64.6 ° C, whereas the high alcohol used in the present invention has a high freezing point (freezing point) and a low boiling point (boiling point) and thus has a low volatilization rate. Alcohol does not freeze by forming a higher alcoholic solution with snow and frost-dissolved water.

이러한 고비점의 고급알콜 성분으로서 이소프로필알콜 3 ~ 8 중량%와 에틸렌글리콜 2 ~ 4 중량% 그리고 프로필렌글리콜 2 ~ 4 중량%를 함유시킬 때 본 발명에 요구하는 최대효과를 얻을 수 있는 바, 이 경우 빙결점은 -20℃이하를 유지하게 된다. 특히, 에틸렌글리콜과 프로필렌글리콜은 흡습성이 매우 강하므로 고급알콜 성분으로서 함유되면 창유리에 흡습성 필름을 형성하여 운전자의 시야를 보다 맑게 유지한다.The maximum effect required for the present invention can be obtained when containing 3 to 8% by weight of isopropyl alcohol, 2 to 4% by weight of ethylene glycol and 2 to 4% by weight of propylene glycol as the high boiling point alcohol component. If the freezing point is kept below -20 ℃. In particular, since ethylene glycol and propylene glycol are very hygroscopic, when contained as a higher alcohol component, a hygroscopic film is formed on the window glass to keep the driver's vision clearer.

또한, 본 발명에서는 상기에서 설명한 고비점의 고급알콜 이외에도 양이온성 계면활성제를 함께 함유시켜 발수능을 부여하는 바, 이로써 이들 서로간의 상승효과(synergy effect)로 인하여 보다 우수한 성애제거능 및 발수능을 발휘하게 된다.In addition, in the present invention, in addition to the high-boiling high-alcohol described above, cationic surfactants are added together to impart water repellency, thereby exhibiting superior defrosting ability and water repellency due to synergy effects between them. Done.

일반적인 유리세정제가 세정효과를 얻기 위해 음이온 또는 비이온 계면활성제를 사용하고 있는데 반하여, 본 발명에서는 양이온성 계면활성제를 사용함으로써 세정효과는 물론이고 이와 더불어 자동차 유리면에 발수능을 창출하여, 폭우에 의한 물필름 형성을 방지함으로써 운전자의 시야를 맑게 유지한다. 이때, 양이온성 계면활성제로는 디메틸세틸암모니움 클로라이드 등을 사용한다. 본 발명자의 실험결과에 따르면, 양이온성 계면활성제로서 예컨대 디메틸세틸암모니움 클로라이드를 0.2 ∼ 0.5 중량% 첨가한 경우, 시속 60 ∼ 70킬로미터로 운전할 때 탁월한 발수작용으로 인하여 폭우 중에서도 와이퍼를 사용치 않고서도 시야를 맑게 유지할 수 있었다.While general glass cleaners use anionic or nonionic surfactants to obtain a cleaning effect, in the present invention, cationic surfactants are used to generate water repellency on the glass surface of the automobile as well as the cleaning effect. Keeps the driver's vision clear by preventing water film formation. At this time, dimethyl cetyl ammonium chloride or the like is used as the cationic surfactant. According to the experimental results of the present inventors, when 0.2 to 0.5% by weight of dimethylcetylammonium chloride is added as a cationic surfactant, the wiper is not used even during heavy rains due to its excellent water repellency when operating at 60 to 70 kilometers per hour. I could keep my vision clear.

이상에서 살펴본 바와 같이, 본 발명에 따른 자동차 유리세정제는 고비점의 고급알콜과 양이온성 계면활성제를 특정 함량범위로 함께 함유하고 있어 성애제거능 및 발수능을 동시에 보유하므로써 겨울의 혹한이나 여름의 폭우 중에서도 항상 맑은 시야를 보장하여 안전운전에 기여하게 된다.As described above, the automotive glass cleaner according to the present invention contains high-alcohol high alcohol and cationic surfactant together in a specific content range, thereby maintaining both defrosting ability and water repellency, even in the cold or the heavy rain of winter. It ensures clear vision at all times and contributes to safe driving.
