Cleanser for vehicle windscreen

Abstract

The invention relates to a detergent for automobile windshields, in particular to a detergent for antifogging automobile windshields with the minimum using temperature of minus 40 DEG C; the detergent mainly consists of the raw materials with the weight (percent): water solution with 30 percent of coconut oil amide propyl betaine: 1 to 5, ethylene glycol monobutyl ether: 1 to 15, propanediol: 10 to 15, water solution with 50 percent of alkyl glucoside: 1 to 10, p-nitrobenzoic acid: 0.16 to 3, water solution with 30 percent of cocamidopropylamine oxide: 1 to 2, isopropanol: 30 to 50 and tributyl phosphate: less than or equal to 0.01; the preparation method is that firstly the raw materials are dissolved, and the dissolved raw materials are uniformly mixed and the rest water is added and the raw materials and the water are uniformly stirred to obtain the detergent. The product which is colorless transparent liquid can be used in winter in most areas and can clean common fouling on the automobile windshields; the product has certain antifogging effect and reduces the occurrence of traffic accidents; most of the raw materials adopted by the detergent are novel green environmental protective surfactants which can be well degraded and can effectively reduce pollution to the environment; the product is wide in application range and has wider market prospects.

Description

Technical field: [0001] The invention relates to an automobile windshield cleaning agent, in particular to an anti-fog automobile windshield cleaning agent with a minimum service temperature of -40°C, and belongs to the technical field of chemical product manufacturing. Background technique: [0002] The temperature in winter in the northern region is generally around minus 25 degrees Celsius. Due to the large thickness of the windshield of the car cab and the large temperature difference between the inside and outside of the cab, during driving in winter, a large amount of suspended water vapor in the cab gathers on the low-temperature glass, producing a layer of indistinct mist , as the temperature continues to drop, a thin layer of ice crystals will form on the windshield, and the driving environment with low visibility will bring certain difficulties to the driver's operation and easily cause a car accident. Most of the current automobile windshield defrosting method ad...

Problems solved by technology

Due to the large thickness of the windshield of the car cab and the large temperature difference between the inside and outside of the cab, during driving in winter, a large amount of suspended water vapor in the cab gathers on the low-temperature glass, producing a layer of indistinct mist , as the temperature continues to drop, a thin layer of ice crystals will form on the windshield, and the driving environment with low visibility will bring certain difficulties to the driver's operation and easily cause a car accident

Most of the current car windshield defrosts are blown by a hot fan, which consumes a lot of power and is easy to form fog, which is difficult to dissipate quickly
