Automotive glass cleaner
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.
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.
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
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.
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.
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.
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.
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.
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.
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.
Referring to the present invention in more detail as follows.
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.
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.
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.
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.
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.
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.
