자동차용 라디에이터 누수방지제 조성물{The Composition of Radiator Stop-Leak}Radiator Leak-proof composition for automobiles {The Composition of Radiator Stop-Leak}

본 발명은 자동차용 라디에이터 누수방지제 조성물에 관한 것으로, 더욱 상세하게는 목분, 아크릴아마이드, 젤라틴, 알긴산소다, 벤조트리아졸, 아질산소다 및 에틸렌글리콜을 일정 함량으로 함유시켜 누수방지제 조성물을 제조함으로써 자동차의 냉각시스템내 누수발생시 그 부분의 누수를 신속하게 차단시키는 효과를 가지는 자동차용 라디에이터 누수방지제 조성물에 관한 것이다.The present invention relates to a radiator leakage preventing agent composition for automobiles, and more particularly, containing wood flour, acrylamide, gelatin, sodium alginate, benzotriazole, sodium nitrite and ethylene glycol in a predetermined amount to prepare a leakage preventing composition of an automobile. The present invention relates to a radiator leakage preventing agent composition for automobiles having the effect of quickly blocking the leakage of the part when leakage occurs in the cooling system.

자동차 내연기관의 온도를 적절히 유지하기 위해 냉각시스템 내에 냉각수가 사용되어 지고 있다. 이때 냉각수가 누수에 의해 부족하게 되면 엔진이 과열되어 오버히터 현상이 일어나고 고장의 원인이 된다. 냉각수가 누수되는 원인으로는 냉각시스템을 구성하는 각종 부품의 연결 부위 조임이 느슨해 지거나 외부로부터 물리적인 충격 또는 냉각수의 부식방지 능력부족으로 냉각시스템 내 금속부품의 부식이 발생하여 누수가 된다. Cooling water is used in the cooling system to properly maintain the temperature of the automotive internal combustion engine. At this time, if the cooling water is insufficient due to leakage, the engine is overheated, overheating phenomenon occurs and cause a failure. The leakage of the cooling water may be caused by loosening of the connection parts of various components constituting the cooling system or by corrosion of metal parts in the cooling system due to physical shock from the outside or lack of corrosion protection of the cooling water.

이러한 누수 부위를 차단키 위하여 종래에는 냉각수에 누수방지제를 첨가하였으나, 종래 누수방지제는 목분의 입자가 고르지 않고, 응집제 농도가 맞지 않아 누수방지제 주입 후 상당 기간동안 기다려야 누수된 부분이 막히거나, 누수량을 약간 줄일 정도로 확실한 효과를 보기가 어려웠으며, 고르지못한 응집제의 입자가 라디에이터의 냉각수통로를 막아 엔진이 과열되는 경우가 있었다. 또한 누수방지제 성분과 부동액의 각종 성분들이 맞지않아 누수방지제 투입 후 냉각계통의 부식과 고무부품들의 팽윤, 부동액 수명의 감소시키는 등의 어려움이 있었다.In order to block the leakage site, a leak prevention agent was added to the cooling water in the related art, but the conventional leak prevention agent has an uneven concentration of wood powder and the concentration of the coagulant does not match, so that the leaked part may be blocked or leaked. It was difficult to see a definite effect, with a slight reduction, and uneven coagulant particles blocked the radiator coolant passages, resulting in engine overheating. In addition, the leakage preventive components and various components of the antifreeze did not match, there was a problem such as corrosion of the cooling system, swelling of rubber parts, reduction of the antifreeze life after the leakage inhibitor is added.

이에, 본 발명에서는 상기와 같은 종래의 자동차용 라디에이터 누수방지제 조성물이 가지고 있는 문제점을 극복하고자 노력한 결과 목분, 아크릴아마이드, 젤라틴, 알긴산소다, 벤조트리아졸, 아질산소다 및 에틸렌글리콜을 일정 함량으로 함유시켜 제조한 누수방지제 조성물을 냉각수 중에 투입하면 누수방지제의 투입후의 누수부분의 틈세를 빠른시간에 막을뿐만 아니라 냉각시스탬내 들어있는 부동액의 성능에 전혀 영향을 주지않음을 알게되어 본 발명을 완성하였다.Therefore, in the present invention, as a result of trying to overcome the problems of the conventional car radiator leakage preventing agent composition as described above containing wood powder, acrylamide, gelatin, sodium alginate, benzotriazole, sodium nitrite and ethylene glycol in a certain amount When the prepared anti-leakage agent composition was added to the cooling water, the present invention not only prevents the leakage of the leakage portion after the leakage-inhibitor addition but also affects the performance of the antifreeze contained in the cooling system.

따라서, 본 발명은 자동차의 냉각시스템내 누수발생시 그 부분의 누수를 신속하게 차단시키는 효과를 가지는 자동차용 라디에이터 누수방지제 조성물을 제공하는데 그 목적이 있다. Accordingly, an object of the present invention is to provide a radiator leakage preventing agent composition for automobiles, which has an effect of quickly blocking the leakage of a portion thereof when a leak occurs in a cooling system of an automobile.

본 발명은 목분 10 ∼ 13 중량%, 아크릴아마이드 1.0 ∼ 1.6 중량%, 젤라틴 1.0 ∼ 2.0 중량%, 알긴산소다 0.1 ∼ 0.5 중량%, 벤조트리아졸 0.1 ∼ 0.3 중량%, 아질산소다 0.1 ∼ 0.5 중량% 및 에틸렌글리콜 28 ∼ 35 중량%가 함유된 자동차용 라디에이터 누수방지제 조성물을 그 특징으로 한다.The present invention is wood powder 10-13% by weight, acrylamide 1.0-1.6% by weight, gelatin 1.0-2.0% by weight, sodium alginate 0.1-0.5% by weight, benzotriazole 0.1-0.3% by weight, sodium nitrite 0.1-0.5% by weight and An automobile radiator leakage preventing agent composition containing 28 to 35% by weight of ethylene glycol is characterized by the above-mentioned.

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

본 발명은 자동차의 냉각시스템내 누수방지 기능을 갖는 자동차용 라디에이터 누수방지제 조성물에 관한 것이다.The present invention relates to a radiator leakage preventing agent composition for a vehicle having a leakage preventing function in a cooling system of an automobile.

이와 같은 본 발명의 누수방지제 조성물을 구성성분별로 더욱 상세히 설명하면 다음과 같다.Such a leak prevention composition of the present invention will be described in more detail by component as follows.

먼저, 본 발명은 충전재 역할을 하는 목분을 전체 조성물 중에 10 ∼13 중량% 함유하며, 만일 그 함유량이 10 중량% 미만이면 누수되는 부분의 차단이 어렵고, 13 중량%를 초과하면 라디에이터의 코어를 막아 엔진의 냉각성능이 떨어질 수 가 있다. 또한, 상기 목분은 입자 크기가 20 메쉬 이상의 것을 사용하는 것이 바람직하다.First, the present invention contains 10 to 13% by weight of the wood powder acting as a filler in the total composition, if the content is less than 10% by weight is difficult to block the leaking portion, if it exceeds 13% by weight to block the core of the radiator Engine cooling may be impaired. In addition, the wood powder is preferably used having a particle size of 20 mesh or more.

그리고, 본 발명은 응집제로 아크릴아마이드, 젤라틴, 알긴산소다 등을 사용하며, 그 함유량은 전체 조성물 중에 아크릴아마이드 1.0 ∼ 1.6 중량%, 젤라틴 1.0 ∼ 2.0 중량% 및 알긴산소다 0.1 ∼ 0.5 중량% 함유하는 것이 바람직하다.In the present invention, acrylamide, gelatin, sodium alginate and the like are used as flocculants, and the content of the acrylamide is 1.0 to 1.6% by weight, 1.0 to 2.0% by weight of gelatin and 0.1 to 0.5% by weight of sodium alginate. desirable.

특히, 수용액에서 응집성능이 우수한 아크릴아마이드의 경우 1.0 중량% 미만 함유하면 누수방지의 효과가 없고, 1.6 중량%를 초과하여 함유하면 더 이상의 효과는 기대하기 어렵고 원가만 상승된다. 또한, 냉각수의 주성분인 에틸렌글리콜에서 응집성능이 우수한 젤라틴의 경우 1.0 중량% 미만 함유하면 누수방지의 효과가 없고, 2.0 중량%를 초과하면 냉각수의 흐름을 방해한다. 그리고, 알긴산소다의 함유량이 0.1 중량% 미만이면 누수차단 시간이 길어지며, 0.5 중량%를 초과하면 냉각계통의 금속부품에 대한 방식성능을 떨어뜨리는 문제점이 있다. In particular, when acrylamide having excellent cohesive performance in aqueous solution contains less than 1.0 wt%, there is no leakage preventing effect, and when it contains more than 1.6 wt%, further effects are difficult to expect and only cost increases. In addition, in the case of gelatin having excellent cohesive performance in ethylene glycol, which is the main component of the cooling water, containing less than 1.0% by weight does not have an effect of preventing leakage, and when it exceeds 2.0% by weight, the flow of cooling water is hindered. In addition, when the content of sodium alginate is less than 0.1% by weight, the leakage blocking time is long, and when the content of sodium alginate is more than 0.5% by weight, the corrosion resistance of the metal parts of the cooling system is deteriorated.

또한, 본 발명은 냉각기관내 부식방지를 위하여 벤조트리아졸과 아질산소다를 전체 조성물 중에 각각 0.1 ∼ 0.3 중량%, 0.1 ∼ 0.5 중량% 함유하는 것이 바람직하다. 이때, 벤조트리아졸의 함유량이 0.1 중량% 미만이면 냉각시스템내 동계부품의 부식방지에 어려움이 있으며, 0.3 중량%를 초과하면 아연으로된 부품에 부식을 일으킬 수가 있다. 그리고, 아질산소다의 함유량이 0.1 중량% 미만이면 냉각시스템 중 철계부품의 방식에 어려움이 있으며, 0.5 중량%를 초과하면 알루미늄부품에 영향을 준다.In addition, the present invention preferably contains 0.1 to 0.3% by weight and 0.1 to 0.5% by weight of benzotriazole and sodium nitrite in the total composition, respectively, in order to prevent corrosion in the cooling engine. At this time, when the content of benzotriazole is less than 0.1% by weight, it is difficult to prevent corrosion of the copper-based parts in the cooling system, and when it exceeds 0.3% by weight, the parts made of zinc may be corroded. In addition, if the content of sodium nitrite is less than 0.1% by weight, there is a difficulty in the method of the iron-based components in the cooling system, if the content of more than 0.5% by weight affects the aluminum parts.

본 발명은 냉각수의 주성분인 에틸렌글리콜을 전체 조성물 중에 28 ∼ 35 중량% 함유하며, 만일 그 함유량이 상기 범위를 벗어나면 조성물의 첨가제에 대한 분산성과 저장안정성에 문제가 있다.The present invention contains 28 to 35% by weight of ethylene glycol, which is the main component of the cooling water, in the total composition. If the content is outside the above range, there is a problem in dispersibility and storage stability of the additive of the composition.

본 발명의 자동차용 라디에이터 누수방지제의 조성물은 상기 성분의 외에 나머지 성분으로 물을 함유한다.The composition of the automobile radiator leakage preventing agent of the present invention contains water as the remaining components in addition to the above components.

위와 같은 조성 및 함량으로 구성된 본 발명의 자동차용 라디에이터 누수방지제의 조성물은 누수차단시간 단축과 부식방지성능 등의 장점이 있으므로 자동차용 라디에이터 누수방지에 효과적이다.Radiator leakage preventing composition for automobiles of the present invention composed of the composition and content as described above is effective in preventing the leakage of a radiator for automobiles because it has advantages such as shortening the leakage blocking time and corrosion resistance.

이하, 본 발명을 실시예에 의거하여 더욱 상세하게 설명하겠는바, 본 발명이 실시예에 의하여 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited by Examples.
