Abstract

The invention belongs to the technical field of cleaning agent and particularly relates to a cleaning agent of a refining device. The cleaning agent of the refining device comprises the following components in parts by weight: (1) 38-57 parts of D-limonene; (2) 9-13 parts of polyether; (3) 4-8 parts of son oil fatty acid monoethanol amine; (4) 4-12 parts of dodecylbenzene sulfonic acid; (5) 0.5-3.5 parts of butylcellosolve; and (6) 6.5-44.5 part of water. The invention also discloses a preparation method of the cleaning agent. The cleaning agent of the refining device has the advantages of energy conservation, safe use, pollution reduction, labour condition improvement, good cleaning effect, and the like and can be widely applied in the oil refining device along with the enhancement of the environmental awareness. The cleaning agent has wide application range, is mainly used for cleaning pipelines, containers and heat exchangers of the oil refining device and can be also used for cleaning machining parts, device parts and mechanical devices to be maintained.

Description

technical field [0001] The invention relates to a cleaning agent and the technical field of preparation thereof. Background technique [0002] Existing a kind of application number is that the Chinese invention patent of CN1339579A name is called " water-based microemulsion cleaning agent for heavy oil pollution and preparation method thereof " proposes a kind of formula. It is composed of water, oily solvent, surfactant, co-surfactant and electrolyte. The brine and the oil phase containing surfactant are stirred by a high-speed mixer to make a liquid-liquid dispersion system, which has transparency, low viscosity and isotropy System stability features. The oily solvent is one or more of kerosene, ethyl acetate, butyl acetate, low-carbon alcohols, and alcohol ether organic solvents. The added amount is 0.01-10%, preferably 1-8%. The surfactant is one or more of anionic surfactants, nonionic surfactants, zwitterionic surfactants and cationic surfactants. The added amount ...
