Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of glass cleaning solution, and particularly relates to a high-efficiency glass cleaning solution for vehicles and a preparation method thereof. BACKGROUND

[0002] During driving, the automobile is impacted by pollution particles such as coal ash, dust and insects, and the pollution particles are adhered to the glass to form dirt which is difficult to remove. The glass cleaning solution has a high wetting, dissolving and dissociating dispersion effect, and has a very significant dirt removal effect. In particular, the glass cleaning solution is sprayed onto the automobile glass through a nozzle, and the glass is cleaned by starting the wiper, so that the glass is easily cleaned, the glass is not damaged by the irregular small sand particles carried by the wiper, and the glass is effectively protected, and the glass cleaning solution also has a certain anti-fog effect.

[0003] However, the cleaning ability of the automobile glass cleaning solution on the market is generally low, and the glass with oil stains cannot be cleaned well. Although the special oil film removing glass cleaning solution has good cleaning effect, the glass cleaning solution has the problem of excessive solid particle residue after evaporation due to excessive addition of the surfactant.

[0004] In addition, most of the glass cleaning solutions on the market are not comprehensively considered, especially when the glass cleaning solution is used with the wiper, the glass cleaning solution with the defoaming agent can cause abnormal sound of the wiper, and the glass cleaning solution with ethylene glycol can cause the surface of the windshield to be blurred after being cleaned by the wiper. SUMMARY

[0005] Therefore, the application aims to provide a high-efficiency glass cleaning solution for vehicles and a preparation method thereof, which has high cleaning effect and is suitable for use with the wiper.

Compared with existing technologies, this invention uses three surfactants—FMES, FMEE, and sodium alkyl alcohol polyether sulfate—as active, cleaning, degreasing, and lubricating components. FMEE and FMES both have excellent degreasing and dewaxing capabilities and are easily soluble in water, while also possessing low pollution and high stability. The sodium alkyl alcohol polyether sulfate surfactant has highly efficient foaming properties, which can effectively lubricate the windshield wipers during operation, reducing abnormal noise during wiper operation, and further enhancing the foaming and degreasing film removal effects of the windshield washer fluid.
