High-foam easy-rinsing water-saving car washing liquid

Technical Field

The invention relates to the technical field of cleaning products for vehicles, in particular to a high-foam easy-rinsing water-saving vehicle washing liquid and a preparation method thereof.

Background

Car washing is required when the car body is covered with some dust, bird droppings, shellac, gum, etc., and thus is the most basic automobile maintenance item. According to research and market discovery, no matter the general low-middle-end special car washing store or the high-end maintenance store, the good fine and smooth feeling of foam in the car washing process is pursued to be presented to car washing car owners. They therefore have a clear requirement for high foaming properties in car wash products. However, foam generated by a high-foaming washing product is not easy to rinse, residual foam needs to be washed by a large amount of water, otherwise, the position of the foam is dried and marks are generated at the corresponding position behind the automobile, so that the cleanness after the automobile is washed is low.

Therefore, the contradiction between the high foaming performance requirement of the car washing liquid in the car washing market and the waste of water resources is to be solved urgently.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a high-foam easy-rinsing water-saving vehicle washing liquid which has compact foam performance and easy rinsing performance and aims to solve the problems in the background art.

Foams are dispersions of gas dispersed in a liquid and are thermodynamically unstable systems. In order to form stable foams, foaming agents, foam stabilizers and the like must be added in addition to the gas phase and the liquid phase, and defoaming agents are required to be added for defoaming. Mechanisms of foam disappearance include liquid film drainage and gas diffusion in the foam: therefore, the strength of the absorption layer film at the interface is enhanced, the viscosity of the liquid film is increased, and the foam stabilizing effect is facilitated; otherwise, the strength of the adsorption layer film at the interface is reduced, the year of the liquid film is reduced, and the defoaming effect is facilitated.

Self-assembled worm micelles, called "living polymers", form a three-dimensional network when their concentration exceeds the critical entanglement concentration, giving the solution the properties of a gel, giving it the properties of a gel, with high viscosity and shear thinning. Worm micelles have been used in the fields of household washing products as well as personal care products, oil field exploitation, etc. However, the application of the worm micelle technology in the vehicle washing products is rarely reported;

the worm micelle technology is introduced into the car washing liquid to improve the viscosity of the car washing liquid and enhance the strength of a liquid film, and the foam is stable under the condition of no shearing force; when the condition of shearing force, the carwash viscosity diminishes, reduces liquid film intensity, and the foam easily disappears, and through the mode of shearing force response viscosity, the water conservation carwash that satisfies the fine and close high bubble performance of carwash simultaneously can promote the rinsing performance of foam again has the dual advantage of satisfying customer's performance demand and water economy resource simultaneously.
