Abstract
The invention provides a glass cleaner. The cleaner comprises a nonionic surfactant, an anionic surfactant, a corrosion inhibitor, an antifreezing film-forming agent, a lubricant and a solvent. The invention also provides application of the glass cleaner to the cleaning of front windshields of trains, in particular application of the glass cleaner to the cleaning of front windshields of motor trains. The cleaner has extremely strong decontamination capacity, and can quickly and effectively remove pollutants which appear on windshields of trains running at a high speed; the cleaner has higher ambient temperature adaptability, and can be used at the temperature of between minus 40 and 60 DEG C; the pH value is 6.8 to 7.2, and the cleaner has lower corrosivity; the cleaner has high lubricity and can prevent the windshields from being bruised; an antifreezing film-forming component is added and can achieve the effects of anti-icing and demisting; and the cleaner does not contain components which are toxic or irritant to human bodies such as methanol, ammonia water and the like.
Description
technical field [0001] The invention relates to a glass cleaning agent and an application thereof, in particular to a front windshield cleaning agent of an EMU and an application thereof. Background technique [0002] With the development of high-speed railways, EMUs have been put into use in large numbers. When the EMU is moving at high speed (generally above 250km / h), the front windshield is often polluted by shellac, bird droppings, small animal corpses, lubricating oil, gasoline and diesel oil; in rainy and snowy days, there are also rain and Ice and snow will affect the driver's line of sight and cause great traffic safety hazards. In addition, the running distance of EMUs is long, and some EMUs need to travel from the cold northeastern region to the warm southern region. At present, there is no effective EMU front windshield cleaning agent that has both good cleaning ability and low temperature resistance (below -40°C). [0003] Domestic EMU front windshield cleaner...
