Technical Field

The invention belongs to the technical field of car washing essence, and particularly relates to a multi-ion micro-gold-plating car washing essence, and a preparation method and application thereof.

Background

In the car washing industry, it is very common to use inferior, toxic and harmful chemical cleaning products, and the sewage after car washing is discharged directly into the urban domestic drainage system. In the above sea, the total amount of private cars in the Shanghai in 2019 is about 415.8 thousands, the total discharge of car washing sewage in one year is 33 hundred million liters, and the total consumption of car washing liquid is 1247 thousand liters. These car washing liquids contain chemical additives such as surfactants and phosphorus which are difficult to degrade, which cause serious damage to the whole environment and are very serious problems in front of the people. The harm of the surfactant to the ecological environment has four main aspects: 1. damage to soil; 2. damage to water bodies; 3. damage to living beings; 4. damage caused in the self-degradation process.

At present, advanced foreign countries do not have great innovation in the aspect of using a detergent for washing vehicles, and mainly achieve the purpose of environmental protection in the aspects of saving water, saving energy, recycling, reducing emission and the like.

However, the prior art restricts the development of water conservation and environmental protection: on one hand, the water consumption is less, so that more foam remains, and on the other hand, the dirt can be removed only by wiping with more force, so that the vehicle paint is easy to scratch.

In addition, the protective vehicle paint in the market uses organic polymers such as synthetic wax, silicone oil and the like, and the components are difficult to degrade and cause harm to the environment.

In view of the above, there is a need to provide a new car washing liquid to solve the drawbacks of the prior art.

On the basis of the technical scheme, the invention can further have the following specific selection or optimized selection.

Specifically, the lithium ion-containing compound is one or two of spodumene and lepidolite, the sodium ion-containing compound is one or two of sodium bicarbonate and sodium hydroxide, the potassium ion-containing compound is sylvine, the magnesium ion-containing compound is magnesium oxide or magnesium carbonate, the silicon ion-containing compound is wollastonite, and the germanium ion-containing compound is germanium oxide.

Specifically, in the lithium ion-containing compound, the concentration of lithium ions is 3.2-5.5 mM; in the compound containing sodium ions, the concentration of the sodium ions is 5.2-11.5 mM; in the compound containing potassium ions, the concentration of potassium ions is 4.0-8.0 mM; in the compound containing magnesium ions, the concentration of the magnesium ions is 0.001-0.002 mM; in the compound containing silicon ions, the concentration of the silicon ions is 0.005-0.010 mM; the concentration of germanium ions in the compound containing germanium ions is 0.025-0.035 mM.

In addition, the invention also provides a method for preparing the polyion micro-gold-plating car washing essence, which comprises the following steps:

1) respectively weighing a lithium ion-containing compound, a sodium ion-containing compound and a potassium ion-containing compound according to the concentration of each ion, adding the sodium ion-containing compound into weighed deionized water accounting for one tenth of the total amount required, stirring for 20-30 minutes, then sequentially adding the lithium ion-containing compound and the potassium ion-containing compound, and reacting for 1 hour under stirring to obtain ionic liquid I;

2) adding the rest of deionized water into the ionic liquid I obtained in the step 1), and stirring for 1 hour to obtain ionic liquid II;

3) weighing a compound containing germanium ions according to the concentration of the germanium ions, adding the compound into the ionic liquid II obtained in the step 2), and reacting for 1 hour under stirring to obtain ionic liquid III;

Specifically, the lithium ion-containing compound, the potassium ion-containing compound and the silicon ion-containing compound in the step 1) are crushed to a particle size of not more than 0.1mm in the step 5).

In addition, the invention also provides application of the polyion micro-gold-plating car washing essence in the car washing industry.

It should be noted that although compounds containing different ions may react with each other and even precipitate during the dissolution process, the ion content is the content of ions stably existing in the supernatant after the reaction, and the content of these ions is quite low, which is different from the conventional definition of solubility under the influence of interaction.

Compared with the prior art, the invention has the beneficial effects that:

1. the polyion micro-gold-plating car washing essence does not contain any organic solvent, wax, surfactant and other organic chemical substances, so that the car washing essence has the advantages of no foam, easiness in washing, good washing effect, water saving, environmental friendliness and bright car body after washing.

2. The surfactant with cleaning effect in the traditional vehicle washing liquid has no corrosion prevention effect, and the vehicle washing liquid needs to be additionally added with a preservative to ensure that the product does not deteriorate in the quality guarantee period. However, the active ingredients in the polyion micro-gold-plating car washing essence provided by the invention have the effects of corrosion prevention, sterilization and bacteriostasis besides the cleaning effect, and can be stored for a long time without adding an additional preservative.

3. The surfactant in the traditional car washing liquid generates durable foam which is not easy to disappear in water, and sewage discharged after washing forms an isolation layer on the water surface, so that gas exchange between the water body and the atmosphere is weakened, and the water body smells. Compared with the polyion micro-gold-plating car-washing essence, the polyion micro-gold-plating car-washing essence disclosed by the invention is free of bubbles, and cannot generate the above adverse effect on a water body.

4. In the multi-ion micro gold-plating car washing essence provided by the invention, various active ions are stably and orderly arranged in an aqueous solution through an organic or inorganic chelating technology, wherein lithium is a metal element with the strongest metal activity and the smallest relative atomic weight in known elements. After the car is washed by the car washing liquid added with the lithium, the resident metal elements on the car body are more stably, orderly and compactly arranged, the uneven part damaged by the car paint is filled, a protective layer is formed on the car paint, the hydrophobicity is stronger, the car is brighter after being washed, and water drops are not easy to be retained.
