Abstract

The invention discloses a phosphorus-free automobile cleaning solution and a preparation method thereof. The cleaning solution comprises the following components in percentage by weight: 6.5-48.0% of a surfactant, 4.2-26.0% of a washing assistant, 1.0-15.0% of a penetrating agent, 0.05-1.0% of a leveling film forming agent and the balance of deionized water. The preparation method comprises the following steps: (1) mixing fatty alcohol-polyoxyethylene ether sodium sulfate with a solubilizer, and adding the deionized water; (2) mixing with the surfactant, the phosphorus-free metal chelating agent, the penetrating agent and the leveling film forming agent in the formula; (3) mixing the mixture with an anti-redeposition agent and an inorganic base; and (4) standing to obtain the cleaning solution. The automobile cleaning solution provided by the invention can realize wiping-free cleaning, is high in cleaning rate, can form an anti-fouling film after cleaning, is environment-friendly and can be degraded easily; and the preparation method provided by the invention is mild in condition and suitable for large-scale production.

Description

technical field [0001] The invention belongs to the field of cleaning compositions, and more specifically relates to a phosphorus-free car cleaning solution and a preparation method thereof. Background technique [0002] With the extremely rapid development of the automobile industry, car cleaning agents have a huge market development space. Various types of car cleaning agents have been developed. According to the appearance of the cleaning agent, the cleaning agent can be divided into two types: powder and liquid. They generally consist of surfactants and detergent builders. [0003] Currently commercially available car shell cleaning agents require pre-washing and sponge wiping in the cleaning process, resulting in scratches on the car shell and loss of luster on the car paint surface. After washing the car, additional steps are required to restore the gloss of the paintwork. [0004] At the same time, commercially available cleaning agents, especially car shell clean...
