Abstract

The invention discloses a special surfactant composition for mixed oil stain cleaning, and a preparation method thereof. The surfactant composition comprises the following components, by weight, 40-70 parts of an epoxyethane epoxypropane block polyether, 5-30 parts of modified isomeric alcohol polyoxyethylene ether, 2-20 parts of polyvinylpyrrolidone, 1-20 parts of fatty alcohol polyoxyethyleneether carboxylate and 1-10 parts of a dispersant. The surfactant composition provided in the invention has the advantages of continuous low foaming, good mixed oil stain cleaning force, difficult precipitation in an alkaline solution, easy rinsing, low cost, and environmental protection, and has a good market prospect.

Description

technical field [0001] The invention relates to the field of cleaning agents, in particular to a special surfactant composition for cleaning mixed oil stains and a preparation method thereof. Background technique [0002] Surfactant refers to a substance that has fixed hydrophilic and lipophilic groups, can be aligned on the surface of the solution, and can significantly reduce the surface tension. Surfactants are widely used, especially in the fields of descaling and washing. There are many kinds of surfactants for cleaning, such as LAS (sodium dodecylbenzene sulfonate), AES (sodium fatty alcohol polyoxyethylene ether sulfate), AEO 9 (Lauryl polyoxyethylene 9 ether), OP-10 (Alkylphenol polyoxyethylene ether), but these surfactants are not strong in cleaning mixed oil stains, and these surfactants have high foam, so they need to be added Defoamer, but after adding the defoamer, although a certain defoaming effect can be obtained, but because the hydrophobic base will combi...
