Abstract

The invention relates to an efficient environment-friendly type water-based metal degreasant and belongs to the technical field of metal surface treatment. The efficient environment-friendly type water-based metal degreasant comprises the following chemical components of, by mass, 1.2%-1.8% of alkylphenol polyoxyethylene ether, 0.4%-0.8% of alpha-sodium olefin sulfonate, 0.3%-0.6% of sodium xylenesulfonate, 0.2%-0.3% of thiourea, 0.5%-1.0% of sodium carbonate, and the balance deionized water. According to the water-based metal degreasant, the alkylphenol polyoxyethylene ether and the alpha-sodium olefin sulfonate are adopted for compounding, and meanwhile, a certain amount of sodium xylene sulfonate, thiourea and sodium carbonate are added, so that a good washing effect is achieved at normal temperature. Meanwhile, the formula is low in alkalinity, corrosivity to metal is low, and the water-based metal degreasant is especially suitable for non-alkali-proof metal, is friendly to the environment and has very good promotional value.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to an efficient and environment-friendly water-based metal degreasing agent. Background technique [0002] At present, there are many kinds of metal degreasing agents, and most of them are cleaned at high temperature. The washing effect at room temperature is not good, or the degreasing agent contains phosphorus, which requires high emission requirements, or the use of organic solvents, the economic cost is high, and there is a certain pollution to the environment. . [0003] A large number of degreasing agents on the market, such as the patent with the authorized announcement number CN109536976A, discloses a multifunctional degreasing agent that can be used at room temperature and has a good comprehensive ability to remove oil and wax, and the oil removal rate can reach 99%. The degreasing agent contains phosphate potassium salt. Due to its eutrophic effect, phosph...
