Abstract

The invention provides a degreaser and a preparation method thereof. The degreaser comprises an emulsifier, a complexing agent, a surfactant and an adsorbent; and the adsorbent is aluminum hydroxide. The invention also provides a preparation method of the degreaser. The degreaser has an excellent degreasing effect, and has an extremely good protection effect on metals in a degreasing solution.

Description

technical field [0001] The invention belongs to the field of surface treatment, in particular to a degreasing agent and a preparation method thereof. Background technique [0002] Cleaning and degreasing processes are often used in the process of metal production and processing. Various metal degreasers that are often used at present mainly include strong acids, strong alkalis and surfactants. They are generally aimed at the treatment of light oil stains on the metal surface. The cleaning efficiency of heavy oil stains is low, which is reflected in the long cleaning time and poor effect; there are many foams, which affect the effect of degreasing and cleaning after degreasing; Toxic and harmful substances such as sodium nitrite, etc., pollute the environment and cause harm to the operator's body; they are easy to cause corrosion to more active metals such as aluminum, which affects subsequent processing. [0003] The patent with publication number CN 102108321A discloses a...
