With the rapid development of national economy and the development of automobile industry, automobiles become one of the basic ways for people to walk instead of families. Vehicle cleaning development is relatively delayed relative to the automotive manufacturing field. At present, the car washing industry adopts a large amount of washing modes to clean the outside of a car, each car uses 100 liters of water, great waste is caused to water resources, frost is added on snow in China with deficient water resources, and water conservation becomes a social consensus. In addition, the phosphorus-containing detergent causes water to be rich in oxidation and microorganisms to be excessively propagated, so that the water is damaged. The car washing and waxing step by step can be completed in at least 60 minutes, which wastes time and has higher cost, and the requirement of daily household car is difficult to meet. The method for realizing waterless car washing by using the phosphorus-free detergent is an important method for realizing green environmental protection, and is an important development direction in the field of car cleaning in future.

At present, corresponding anhydrous vehicle washing liquid and other related products are produced in domestic and foreign markets, and as effective protection of vehicle paint cannot be realized, paint surface scratches in the forms of sun stripes and the like are caused, so that the vehicle paint is difficult to be widely accepted by vehicle owners. In addition, the cleaning and polishing effects are unsatisfactory, and cannot be compared favorably with the traditional cleaning and polishing effects, so that the technical bottleneck needs to be solved urgently.

Example 2

Example 3

The blank control was wiped using the same method with clear water and tested for roughness and cleanliness using aluminum foil to simulate car paint scratches.

The simulated scratch test method is as follows: 1g and 4g of silica particles with average particle sizes of 0.002mm and 2mm were uniformly coated on the aluminum foil, respectively, 2mL of an equivalent amount of oil stain was sprayed, and a wiping test of the same strength was performed using a towel to spray the responsive car wash. And testing the reflectivity, the roughness and the chroma of the wiped aluminum foil. The roughness can reflect the abrasion degree of the sandstone to the aluminum foil, the higher the abrasion is, the lower the light reflection rate is, and the roughness of the aluminum foil which is not wiped is 0.005 mm. The chroma is defined as 100%, and can reflect the oil stain cleaning condition, and the higher the oil stain cleaning degree is, the higher the chroma is, the closer to the initial value is. The reflection rate of the brand new aluminum foil is defined as 100%, and simultaneously the cleanness degree of oil stains and sand dust is reflected. The results obtained are shown in table 1.
