Description

A kind of nano-suspended rinse-free cleaning agent and its preparation method and application

Technical field

The invention belongs to the technical field of cleaning and maintenance, and specifically relates to a rinse-free cleaning agent and a preparation method thereof.

Background technique

With the development of the automobile industry, automobiles have become one of the basic ways for families to travel. Since the invention of the automobile, water has been indispensable for cleaning the car body. When the car body is covered with mud, dust and other dirt, drivers always use a lot of water to clean the dirt on the car surface first. Rinse, wipe dry, and then apply expensive car wax on the washed car surface. All this work not only takes 1-2 hours each time, but is also very labor-intensive, and even more headaches for drivers. Due to the insurmountable shortcomings of car wax itself, such as short protection period, insufficient protection hardness and easy dust collection, it is often necessary to do it 3-4 times a month. Not only does car wax and cleaning agents cost a lot, but also a lot of money. time and labor costs. Compared with the automobile manufacturing field, the development of vehicle cleaning methods is relatively lagging behind. The car washing industry basically uses a large amount of water to clean the exterior of the vehicle. Each vehicle uses 100 to 200 liters of water, causing a huge waste of water resources. In addition, phosphorus-containing detergents cause the water body to become rich in oxidation, and microorganisms multiply excessively, causing water damage. The detergents used in traditional car washing processes are mostly alkaline (pH>10), which will accelerate the aging and yellowing of the varnish on the car paint surface, and even crack and fall off. Therefore, green, environmentally friendly, clean and efficient are important development directions in the field of automotive cleaning.

In recent years, waterless car washes first emerged in European and American countries, and were later introduced to China. The so-called waterless car wash uses detergent and towel wiping to clean the vehicle, without the need for subsequent water flushing and water collection. It helps clean the stains and dirt on the car while forming a thin film to protect the car and reduce damage caused by ultraviolet radiation, acid rain, pollution, etc.

Chinese patent CN100485022C discloses a waterless cleaning agent for automobile casing, which is low-priced and environmentally friendly, but the coating protection effect needs to be further improved. Patent CN1624098A discloses a waterless cleaning agent that can perform comprehensive cleaning and maintenance on the entire car. It has the ability to prevent ultraviolet rays and antistatic electricity, but has limited decontamination and polishing properties.

Therefore, in order to better meet the development of the automobile cleaning industry and the needs of practical applications, it is necessary to propose a resource-saving, environmentally friendly, no-rinse cleaning agent that can effectively protect the paint surface, have good decontamination effects, and is easy to use. .
