Abstract
Described is a method for preparation of stable fatty alcohol emulsion, wherein, fatty acid esters are introduced into an antifoaming agent emulsion system, and an anionic surfactant is added in the late stage of emulsification process in order to further improve the stability of the emulsion. The anionic surfactant is absorbed to the surface of fatty alcohol particles to make the fatty alcohol emulsion more stable under the action of ionic mutual repulsion. The prepared fatty alcohol emulsion has favorable foam elimination and suppression performance in the paper making procedure, and is stable during storage.
