Abstract

The invention relates to the technical field of surfactants, particularly to a stable diesel oil emulsifying composite additive, which comprises the following raw materials by weight: 35-42 parts of an oleic acid ethylene oxide adduct, 30-35 parts of oleic acid triethanolamine, 6-9 parts of glycerin, 0.5-1.5 parts of water, 1-3 parts of potassium hydroxide, 0.5-1.2 parts of sodium petroleum sulfonate, 0.8-1.2 parts of a combustion-supporting agent, 6-8 parts of an increasing agent, and 25-32 parts of light diesel oil. According to the present invention, the emulsifier prepared based on the formula has good stability, can restore a good emulsified state by slightly stirring even if long-term placement, and can be added with a certain corrosion inhibitor according to different water qualities of each place so as to effectively improve the use efficiency of the emulsifier.

Description

technical field [0001] The invention relates to the technical field of surfactants, in particular to a compound additive for stabilizing diesel emulsification. Background technique [0002] Emulsifier is a substance that can improve the surface tension between the various constituent phases in the emulsion to form a uniform and stable dispersion system or emulsion. Emulsifier is a surface active substance with both hydrophilic and lipophilic groups in the molecule. The base, which gathers on the oil / water interface, can reduce the interfacial tension and reduce the energy required to form the emulsion, thereby increasing the energy of the emulsion. [0003] The existing emulsifiers used in diesel preparations have poor surface activity and poor interfacial tension, which cannot meet the growing demand for use. Contents of the invention [0004] In order to overcome the existing above-mentioned shortcomings, the invention provides a stable diesel emulsifying compound addit...
