Problems solved by technology

[0003] The main components of existing metal degreasers are strong acids, strong alkalis and surfactants, etc. They generally can only deal with light oil stains on the metal surface, and have low cleaning efficiency for heavy oil stains, and the cleaning time is long and the effect is also very poor; There are many foams, which affect the degreasing effect and cleaning after degreasing; and the existing degreasing agent contains phosphorus, which is not conducive to environmental protection.

[0033] The preparation method of described isomerism alcohol polyoxyethylene ether sodium sulfate, comprises the following steps at least:

[0034]a. Add 3,5,5-trimethyl-1-hexanol and catalyst magnesium hydroxide into the pressure reactor, connect the propylene oxide metering tank to the pressure reactor, replace the air in the reactor with nitrogen for 3 times, and wait for the reactor to When the temperature rises to 115-120°C, propylene oxide is introduced, the molar ratio of 3,5,5-trimethyl-1-hexanol to propylene oxide is 1:1, the passage is completed within 0.5 hours, and the reaction is continued for 2 hours; The temperature of the kettle rises to 175-180°C, and ethylene oxide is introduced into it. The molar ratio of 3,5,5-trimethyl-1-hexanol and ethylene oxide is 1:5, and the passage is completed within 3 hours. Continue to react for 1h. After the reaction is completed, cool and release the pressure to obtain a colorless and transparent product a. The mass of magnesi...

Description

technical field [0001] The invention relates to the field of degreasing agents, in particular to an environment-friendly degreasing agent. Background technique [0002] Metal surface degreasing is a common process in metal processing or use. Commonly used metal cleaning agents are divided into solvent type, semi-solvent type and water-based type. Among solvent-based metal cleaners, petroleum solvents are flammable, explosive, and a waste of resources. Chlorofluorocarbons are the most commonly used solvent-based metal cleaners, but are banned due to their damage to the atmospheric ozone layer. Therefore, solvent-based metal cleaners are gradually being replaced by semi-solvent and water-based metal cleaners. Compared with the semi-solvent type, the application advantages of the water-based metal cleaning agent are more prominent. [0003] The main components of existing metal degreasers are strong acids, strong alkalis and surfactants, etc. They generally can only deal wit...
