Problems solved by technology

[0003] At present, there are solvent-based cleaning agents, strong acid cleaning agents, and strong alkaline cleaning agents. Solvent-based cleaning agents have the disadvantages of high toxicity and volatility, which do not meet the current environmental protection requirements.
However, strong acid and strong alkaline cleaning agents are highly corrosive, easy to cause human injury, and have certain safety hazards.

Abstract

The invention discloses a microemulsion type oil stain cleaning agent, a preparation method and an application thereof, and belongs to the technical field of oil stain cleaning. The microemulsion type oil stain cleaning agent is prepared by the following components by weight: 1, chlorine-3, fluorocyclohexane 10-26%; methyl ethyl ketone 5-16%; dodecyl fluoroallyl Sodium sulfosuccinate 3-5%; diethylenetriamine 1-3%; pyridinethione urea 0.5-1%; emulsifier 1-3%; and the balance of water. In the embodiment of the present invention, through the synergistic compounding of the above components, the prepared microemulsion type oil pollution cleaning agent can quickly remove the crude oil deposits in the oil pipeline, and the removal rate is high, ensuring that the pipe wall is free of oil and wax, and presents metal luster. The microemulsion type cleaning agent does not contain strong acid and alkali substances, does not damage the human body, is safe and environmentally friendly, and has stable product performance, is not easy to volatilize, and has a high safety factor during storage and transportation.

Description

technical field [0001] The invention relates to the technical field of oil stain cleaning, in particular to a microemulsion type oil stain cleaning agent and a preparation method and application thereof. Background technique [0002] During the transportation of crude oil, paraffin, colloid, asphaltene and mechanical impurities in crude oil, as well as sediment are gradually deposited in the oil pipeline. These pipeline deposits reduce the pipeline capacity. In order not to affect the properties of the modified transmission medium and improve the pipeline transportation capacity, it is necessary to clean the sediment in the pipeline; or when the oil pipeline reaches the service life or meets the scrapping standard, the sediment on the inner wall of the pipeline needs to be cleaned, otherwise it will be scrapped If the pipeline loses corrosion protection for a long time, the protective layer will fail due to aging. Under the corrosion effect of electrochemistry and microorgan...
