Description

Cleaning agent and preparation method and application thereof

Technical Field

The invention relates to the field of fine chemical engineering, and particularly relates to a cleaning agent as well as a preparation method and application thereof.

Background

As urban traffic is more and more convenient, pollutants discharged by exhaust gas generated by incomplete combustion exist in a large amount of automobile exhaust on roads, and along with traffic jam, particularly the pollutants are attached to the back of a truck, so that an oil film is formed on automobile glass inevitably. In addition, if the automobile is stopped near the exhaust of a restaurant chimney, a great deal of oil smoke dirt is easily deposited on the surface of the automobile glass, and oil dirt can be formed after the automobile is not treated for a long time. The appearance of an oil film on automobile glass can block the sight of a driver besides the basic aesthetic problem, for example, if the front windshield is not clearly seen in rainy days under the oil film, the sight is seriously influenced by the glare of the opposite high beam at night, and the traffic safety is influenced; or the windscreen wiper is opened in rainy days, the visual field of the front windshield does not become clear after the windscreen wiper is repeatedly wiped, and the effect is not achieved no matter the windscreen wiper is continuously sprayed water or repeatedly wiped.

The traditional cleaning agents for the oil film on the automobile glass are divided into three categories, the first category is neutral liquid cleaning agents, namely, surfactants and solvents are mixed, such as common glass water and concentrated glass water, the neutral liquid cleaning agents can only remove the oil film on the surface of the automobile glass, and the oil film on the bottom layer cannot be effectively removed; the second type is a strong alkaline liquid cleaning agent, namely, strong alkali such as sodium hydroxide and the like are added on the basis of a neutral liquid cleaning agent, and a water-based alkaline cleaning agent which takes an inorganic thickening agent, a friction agent and a surfactant as main raw materials can effectively clean a bottom oil film, but certain corrosion is caused to a glass rubber strip and a plastic part; the third type is a paste cleaning agent, which can effectively clean the oil film on the surface and the bottom layer at the same time, but needs the paste and the glass to be wiped for multiple times, and is time-consuming, labor-consuming and inconvenient to operate. Some pasty cleaning agents are unstable and have the phenomena of layering, particle flocculation and agglomeration, and the like, so that water is extruded from the front part and paste comes out from the rear part when the cleaning agent is used, and the glass scratches can be caused by serious flocculation. Whether the paste cleaning agent is cleaned or not can be checked after the paste cleaning agent needs to be washed in the operation process, so that the paste cleaning agent is very inconvenient for a user and wastes time and labor. In addition, some rubbing sponges are too loose and not tight, so that the friction resistance is not high enough, a large amount of force is required for the rubbing process, and the rubbing time is prolonged.

Therefore, it is necessary to provide a cleaning agent which is stable without adding a surfactant, has a good cleaning effect, and can visually remove an oil film, and can achieve a cleaning effect while cleaning and checking the cleaning effect.
