Problems solved by technology

It is difficult to use general detergent blended products in places with low temperature, and it is easy to freeze and make it impossible to clean the car windows, especially in the cold winter in the north
In the domestic market, there are few qualified products for car window washer liquid to be filled. After some unqualified or even inferior products are selected, it is easy to cause damage to the car, such as paint film peeling off and discoloration due to the use of car window washer liquid. Pipeline blockage, cleaning system plastic aging too fast and other adverse effects, the existing domestic patents and literature on glass cleaning, the main function focuses on cleaning and removing dirt, shellac and other functions, without considering the impact of windshield washer liquid on Compatibility of automotive coatings, plastics, rubber, and protection of metal parts of the cleaning system. The windshield washer fluid that is really used for filling high-end cars must consider the comprehensive protection that the car cleaning system can provide.

Abstract

The invention discloses an automobile air window washing liquid which contains following components by mass percent: 15 percent to 90 percent of methanol, 0.01 percent and 0.5 percent of benzotriazol, 0.08 percent and 0.5 percent of alkyl poly indicant, 0.05 percent to 0.5 percent of fatty alcohol ether sodium sulfate and 0.0005 percent to 0.003 percent of paint. The molecular formula of alkyl poly indicant in de-ionized water is (C6H6O5)nCmH2m+1, wherein n can be an integer between 1 and 8 and m can be an integer between 8 and 12. The invention has the advantages that the automobile air window washing liquid can be evaporated from the surface of windows rapidly without residue and removes shell-lac from window surfaces and also can clean the window surfaces; in addition, the washing liquid has excellent function to prevent the metal of washing system form being oxidized and etched by acid, and can effectively protect all metal parts of pipes of washing system.
