Description

Efficient and environmentally friendly waterless car wash cleaning liquid and preparation method thereof Technical field

The invention belongs to the field of automobile cleaning, and particularly relates to an efficient and environmentally-friendly waterless car wash cleaning liquid and a preparation method thereof.

Background technique

At present, most of the car washes on the market use water and car cleaning agents for car washing, which wastes a lot of water resources and takes a lot of labor. When the vehicle is driving fast, the static electricity on the vehicle body absorbs the dust and sand into the body, forming tiny scratches, and then the dust will fill the naked eye with no visible scratches. High-pressure water flow, rough car wash brush and towel, damage the paint surface, will cause the more washable and dirty, the traditional car wash tap water contains soluble calcium and magnesium compounds and impurities, easy to produce watermark. Gum, animal excrement, insect carcass is difficult to clean, need to wipe repeatedly, easy to hurt the paint surface.

Many automotive car wash liquids (liquids) and car wash powders on the market currently contain a large amount of ionic surfactants, or a mixture of ionic surfactants and nonionic surfactants. For example, CN103627550A contains anionic surfactant sodium lauryl sulfate, dodecyl sulfate triethanolamine, dioctylsulfonated sodium succinate, sodium alkylbenzene sulfonate. CN02149400.2A Environmentally-friendly water-saving car wash liquid uses ionic surfactant octylphenol ethoxylate, which uses boric acid to inhibit bacteria, sterilization and stabilizer. CN 102559401A uses an ionic surfactant fatty acid diethanolamide fatty alcohol using a nonionic surfactant polyoxyethylene ether phosphate, and an anionic surfactant in CN 102492566A includes sodium secondary alkyl sulfonate, dodecyl phosphate The ester potassium salt, sodium alkyl sulfate, etc., nonionic surfactants include ethoxylated alcohols, fatty acid glycerides, polysorbates, fatty acid methyl ester ethoxylates and the like. Since ionic surfactants are mainly irritating and sensitizing to tissues such as skin and eyes, safety and mildness are difficult to ensure.

The invention is a cup-washing powder, the Chinese invention patent No. 201310074954.2, discloses a polyacrylamide used in a cup washing machine powder. The health department has stipulated residual acrylamide content in polyacrylamide industrial products, generally 0.5%-0.05%. The toxicity of polyacrylamide comes from its residual monomer acrylamide (AM). Acrylamide is a neurotoxic agent that has a damaging effect on the nervous system. At the same time, poor stability is easy to fail.

At present, there is no phosphorus in the formula of waterless car wash cleaning liquid (agent). For example, CN2013104819239A has sodium hexametaphosphate, and CN200410033974.6A contains calcium phosphate, which belongs to phosphate, and does not meet environmental protection standards.

The formula contains wax, which is not easy to wipe clean, and there are traces of residue after wiping, especially the black body has white filament residue. CN200410033974.6A, CN02132584.7A, CN200610026720.0A, CN200710037268.2, CN201010557874.9A, CN201510577764.1, CN201510367131.8 contain palm wax or paraffin wax. CN201510367131.8 The formula also contains cyclohexylamine with ammonia smell and is toxic.

The formula has a stimulating taste, and has no flocculation property, and is easy to scratch the paint surface, such as CN01107806.5A, CN03138853.1A, CN200310115183.3A, CN200610026720.0A, CN200610072850.8A, CN200810168533.5A, CN2014106638849A. CN200610072850.8A contains methanol poisonous.

Currently used automotive cleaning agents usually contain nitrogen, phosphorus, ammonia, benzene ions or groups. Compounds containing these ions or groups can achieve rapid and thorough cleaning effects in traditional car wash products, but these compounds have certain properties. The environmental hazard will cause certain pollution and damage to the users and the use environment, and the direct discharge of the waste liquid after cleaning will directly pollute the environment. Therefore, how to develop an environmentally friendly and pollution-free automotive cleaning solution containing no nitrogen, phosphorus, ammonia, benzene plasma or groups, and the performance can reach or exceed the commonly used cleaning liquid containing the above harmful ions, and more The car wash fluid product with maintenance function is a hot spot in current research.
