Problems solved by technology

The traditional car windshield cleaning fluid mainly uses methanol as a solvent. The problem is that methanol is a toxic and harmful solvent. While cleaning the windshield, solvent gas will enter the cab from the car's air conditioning system, and long-term contact will damage the car. cause injury to the insiders, caus

Abstract

The invention relates to an automobile windshield cleaning fluid. The automobile windshield cleaning fluid is prepared from the following components in percentage by mass: 10-40% of alcohol, 5-25% of ethylene glycol, 0.001-0.2% of sodium silicate, 0.01-0.2% of a silicate stabilizer, 0.001-0.2% of long-chain organic acid, 0.05-2% of a surfactant, 0.05-2% of ethylene glycol monobutyl ether, 0.0001-0.005% of a defoaming agent and 0.0001-0.005% of a colorant. Alcohol and ethylene glycol are adopted as a solvent, so that harms of methanol on a human body are effectively avoided; dust and blot on the automobile windshield surface can be quickly cleaned, and thus, the automobile windshield cleaning fluid has performances of being anti-freezing, anti-fogging and lubricant; by virtue of rational compatibility, the cleaning agent has anti-corrosive and inhibiting effects on various metals such as cast aluminum, steel and copper; meanwhile, the adjustment of a pH value of the cleaning agent is realized, so that the automobile windshield cleaning fluid has relatively stable performances, and a simple and practical formula.

Description

technical field [0001] The invention relates to a cleaning fluid, in particular to a cleaning fluid for automobile windshields. Background technique [0002] In addition to quickly removing dust and stains on the surface of the windshield, the car windshield washer fluid also has antifreeze, antifog, and lubricating properties. When used in winter, it can significantly lower the freezing point of the liquid and quickly dissolve the frost. When used in foggy days, it can form a monomolecular protective layer on the glass surface to prevent the formation of fog droplets and ensure the clear and transparent windshield glass. At the same time, it acts as a lubricant between the glass and the wiper to prevent scratches on the glass. Automobile windshield cleaning fluid is mainly composed of antifreeze, water, corrosion inhibitor, defoamer, and dyeing agent. Its key technology is the reasonable mutual matching of various additives. The traditional car windshield cleaning fluid...
