Solid cleaning liquid concentrate and preparation method and application thereof
Technical Field
The invention relates to the field of cleaning liquid, in particular to a solid cleaning liquid concentrate and a preparation method and application thereof.
Background
In our actual life, transparent glass is used for enclosing walls of many buildings, and the glass is easy to be stained with impurities such as greasy dirt and dust after being exposed in the air for a long time, so that periodic cleaning is required, the cleaning requirements are relatively simple, corrosion protection is basically not involved, and in motor vehicles such as automobiles, locomotives and the like, dust, bird droppings, insect carcasses and the like are easy to accumulate on windows and bodies during long-term running and placement. The glass surface is easy to fog and freeze in winter; in summer, a lot of shellac is often stained, greasy dirt, dust and the like are inevitably attached to a windshield at ordinary times, the sight of a driver is seriously influenced, potential safety hazards are caused in the driving process, the attractive appearance and the service life of the vehicle, particularly the service life of a paint surface are also influenced, the response to the requirement of cleaning liquid is strict, the glass surface can be effectively cleaned, and the cleaned residual liquid cannot corrode the adhesive tape on the surface of the vehicle window, the surrounding finishing paint and the coating film.
For the motor vehicle window cleaning liquid, the requirement is higher, but the price is cheaper, the transportation of the glass cleaning liquid with low freezing point also relates to the transportation and storage of dangerous goods, the use is very inconvenient, and the transportation cost of the product which is quite cheaper is more than 50%, so that the cost of the motor vehicle cleaning liquid is high. In recent years, the glass cleaning liquid sold in supermarkets and free of ice points cannot be used in winter, has good quality, cannot meet the requirements of convenience in carrying and economy, and is not suitable for long-term use of vehicles.
At present, solid-state wiper concentrates are sold in domestic markets, most of the solid-state wiper concentrates are produced in small workshops, only the cleaning and instant functions are considered, the functions of corrosion resistance, ageing resistance, scaling resistance and the like of metal parts of a wiper system are not considered, long-term application of the wiper concentrates can not only cause accelerated ageing of wiper strips, but also cause corrosion and fracture of blades or shafts of a wiper motor pump, and quality accidents are caused.
CN104099188a discloses a solid glass water and a preparation method thereof. Wherein, the solid glass water comprises the following raw materials: 2-5 parts of nonylphenoxy polyoxyethylene ether alcohol, 1-3 parts of 1, 2-ethylene tetra-sodium acetate, 5.5-9 parts of sodium lauryl sulfate, 5-7 parts of sodium carbonate, 3-5.5 parts of sodium bicarbonate and 0.5-0.7 part of citric acid. However, the patent does not consider the requirements of corrosion prevention and scale dispersion, the citric acid can only play a slight descaling role, a large amount of scale is easy to cause to block a nozzle for a vehicle which is widely diluted by tap water, the solid glass water is most suitable for cleaning household glass and building glass with low requirements, the glass water prepared by the formula cannot meet the standard requirements of GB23436-2009, and cannot be used for cleaning automobile windows and train window glass, and meanwhile, the patent does not give a specific solution for winter use.
Therefore, research and development of a solid cleaning fluid concentrate with functions of corrosion prevention, scaling prevention, dispersion and aging resistance are of great significance.
