Normal-temperature water-based non-phosphorus rust-proof cleaning agent for heavy oil

Abstract

The invention discloses a normal temperature water-based non-phosphorus rust-proof cleaning agent for heavy oil. The rust-proof cleaning agent comprises an anionic surfactant, a nonionic surfactant and auxiliaries, wherein the mass ratio of the anionic surfactant to the nonionic surfactant to the auxiliaries is (1.5-4): (1.5-4): 1. The cleaning agent comprises the following components in parts by weight: 5 parts of sulfonated fatty acid ester, 6 parts of AEO (alcohol ethoxylate), 2 parts of JFC, 2 parts of sodium carbonate, 2 parts of sodium metasilicate pentahydrate, 2 parts of EDTA (ethylene diamine tetraacetic acid) disodium and 3 parts of dimer acid-modified water-based acrylate. The cleaning agent disclosed by the invention has a relatively high natural degradation effect and overcomes the defect that common cleaning agent has the cleaning function only at a medium temperature or relatively high temperature and the cleaning agent disclosed by the invention has a relatively high cleaning effect at normal temperature. In addition, the cleaning agent disclosed by the invention further overcomes the defect that the existing cleaning agent is poor in anti-rust performance.

Description

technical field [0001] The invention belongs to the technical field of chemicals used in the petroleum industry, and relates to a cleaning agent, in particular to a normal-temperature water-based phosphorus-free heavy oil antirust cleaning agent. Background technique [0002] Early metal cleaning agents mostly used organic solvents, such as gasoline, diesel, kerosene, etc., during the cleaning process. This type of cleaning agent is flammable and expensive due to its low flash point, and causes a large waste of resources and pollutes the environment. The new water-based cleaning agent does not contain the above-mentioned components, is safe and environmentally friendly, has low cost, and has good decontamination effect. It can be used for various metal products, such as carbon steel, copper, zinc, iron, titanium, alloy and other equipment and pipelines. [0003] Water-based metal cleaners use water as a solvent, add acid and alkali, add surfactants and additives to achieve ...

AI Technical Summary

Problems solved by technology

[0005] At present, the quality of domestic washing products is still very rough. Many products can be effectively cleaned at temperatures above 50°C. When the temperature is low, such as normal temperature, the washing effect is obviously insufficient, and the detergent below normal temperature is even less.

And most small and medium-sized enterprises are still using non-environmentally friendly detergents, which brings certain pressure to the environment

Traditional cleaning agents mainly rely on strong alkalinity to improve the cleaning effect, but excessive alkalinity will cause certain harm to operators
