| description | The invention discloses a mineral oil defoaming agent and a preparation method thereof, and relates to the technical field of defoaming agents. The mineral oil defoaming agent is prepared from the following raw materials in parts by weight: 50-90 parts of mineral oil, 5-20 parts of a cationic emulsifier, 5-20 parts of a nonionic emulsifier, 1-10 parts of modified silicon polyether, 0.5-5 parts of a defoaming agent and 0.5-5 parts of a thickening stabilizer, and the molecular structure of the modified silicon polyether has a polyether-siloxane-alkyl structure. The cationic emulsifier and the nonionic emulsifier are selected as the compound emulsifier, so that the emulsifying effect and the stability of the defoaming agent can be improved, and the defoaming agent can be suitable for foam elimination in multiple industries. Besides, modified silicon polyether with a polyether-siloxane-alkyl structure is added, the hydrophilic polyether end of the modified silicon polyether can improve the water solubility of the |
