Abstract

The invention discloses a steel surface microemulsion degreaser and a preparation method thereof. The steel surface microemulsion degreaser is prepared from the following components in parts by weight: 12 to 25 parts of lauryl sodium sulfate, 14 to 28 parts of sodium dodecyl benzene sulfonate, 17 to 32 parts of hexadecyl trimethyl ammonium bromide, 18 to 30 parts of normal propyl alcohol, 13 to 28 parts of isopropyl alcohol, 8 to 19 parts of n-butyl alcohol, 9 to 15 parts of normal hexane, 13 to 26 parts of isooctane, 25 to 40 parts of nano sodium molybdate, 20 to 38 parts of nanosilicon dioxide, and 24 to 38 parts of absolute ethyl alcohol. The steel surface microemulsion degreaser provided by the invention can be used for effectively removing oil stains on steel surfaces, and cannot harm the environment.

Description

technical field [0001] The invention relates to the field of steel surface treatment, in particular to a steel surface microemulsion degreasing agent and a preparation method thereof. Background technique [0002] In the 1940s, scientists described the spontaneous formation of transparent or translucent systems when oils and water were mixed with ionic surfactants and co-surfactants. It was not until 1959 that scientists first referred to the above system as "microemulsion" or "microemulsion". In 1985, a relatively complete definition of microemulsion was put forward: microemulsion is a thermodynamically stable, isotropic and transparent dispersion system generated by two immiscible liquids under the action of surfactant molecular interface film. [0003] Microemulsions are usually transparent, isotropic, thermodynamically stable, oil - Water-surfactant dispersion system. The droplet diameter is about 10-100nm. According to the ratio of oil to water in the system and its...
