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

The water base Phosphorus-free heavy oil anti-rust cleaning agent of a kind of normal temperature
Technical field
The invention belongs to petroleum industry chemical technical field, relate to a kind of clean-out system, the water base Phosphorus-free heavy oil anti-rust cleaning agent of especially a kind of normal temperature.
Background technology
Early stage metal cleaner, in cleaning process, adopts organic solvent to clean, as gasoline, diesel oil, kerosene etc. mostly.This kind of clean-out system due to flash-point lower, inflammable, price costly, and causes larger waste and contaminate environment to resource.Novel aqueous clean-out system is not containing said components, and safety and environmental protection, cost is low, and clean effect is good, may be used for various metal products, as equipment Pipe-Lines such as carbon steel, copper, zinc, iron, titanium, alloys.
Water-based metal clean-out system is solvent with water, adds outside acid, alkali, and interpolation tensio-active agent and auxiliary agent play the object of cleaning.General water-based metal clean-out system is divided into acidity, alkalescence and neutrality three kinds, is also market uses more three kinds.And the tensio-active agent used in clean-out system is very important one side in cleaning performance, it is also the emphasis of research at present.
Alkaline water-based cleaning agent is by adding tensio-active agent in alkali aqueous solution and auxiliary agent forms, alkali can produce saponification to animal-plant oil, and becoming water-soluble salt, tensio-active agent has stronger emulsifying effect to mineral oil, thus reaches effective degreasing washing.With uses merely compared with tensio-active agent, reducing degreasing cost, improve degreasing effect, is the waterborne cleaning agent that use is the widest at present.Except using alkali and tensio-active agent, generally also add some washing assistants, as some alkali inorganic substance: sodium carbonate, water glass, tripoly phosphate sodium STPP etc.Its effect has: (1) reduces the micellar concentration of tensio-active agent; (2) demineralized water; (3) in water, be dispersed into colloid, play the effect of absorption, dispersion dirt, and can prevent dirt from adhering again to metallic surface.
Cleaning product quality domestic at present also seems very coarse, and a lot of product just can reach effective cleaning more than 50 DEG C, and when temperature is lower, as normal temperature, then washing effect is obviously not enough, and the washing composition lower than normal temperature is then less.And most of medium-sized and small enterprises are also at the non-friendly washing composition of environment for use, and this brings certain pressure to environment.Conventional clean agent mainly relies on stronger alkalescence to improve cleaning performance, but base number is crossed conference and brought certain injury to operator.The composite product of the present invention is water-soluble washing agent, and the tensio-active agent of use is not phosphorous, and can at occurring in nature natural degradation, and in addition, the present invention can carry out effective protection against corrosion to metal in cleaning process, and can effectively wash at normal temperatures.
Summary of the invention
The present invention aims to provide the water base Phosphorus-free heavy oil anti-rust cleaning agent of a kind of normal temperature, and object is in order to the efficient heavy oil to metallic surface attachment cleans, and well can carry out protection against corrosion to metallic surface, and the cleaning materials selected is degraded under field conditions (factors).
The present invention is achieved through the following technical solutions:
The water base Phosphorus-free heavy oil anti-rust cleaning agent of a kind of normal temperature, comprise anion surfactant, nonionogenic tenside and auxiliary agent, wherein the mass ratio of anion surfactant, nonionogenic tenside and auxiliary agent is 1.5 ~ 4:1.5 ~ 4:1.
Described anion surfactant is one or more in aliphatic alcohol polyethenoxy ammonium sulfate, amine hydroxybenzene, Sodium dodecylbenzene sulfonate, fatty acid ester sulfonated bodies, and described fatty acid ester sulfonated bodies structure is wherein R is alkyl, two R differences.
Described nonionogenic tenside is one or more in AEO, JFC or polyoxyethylene nonylphenol ether.
Described auxiliary agent is one or more in sodium hydroxide, sodium carbonate, metasilicate pentahydrate sodium, Sunmorl N 60S, sodium tartrate or EDETATE SODIUM.
Clean-out system of the present invention also comprises dimer acid modified water-and acrylate, for forming one deck polymeric membrane in metallic surface in cleaning process.
Clean-out system of the present invention, according to parts by weight, comprises following component:
Preferably, clean-out system of the present invention, according to parts by weight, comprises following component:
During clean-out system preparation of the present invention, first measure respectively certain tap water, first by EDETATE SODIUM, sodium carbonate, Starso, be dissolved into homogeneous phase transparent solution successively according to weight part, again tensio-active agent, high molecular polymer are dissolved into homogeneous phase successively, the two mixing and stirring.
Clean-out system of the present invention uses by cleaning, flooding or spray hyperacoustic processing mode, dilution 20 times before composite substance migration.
Beneficial effect of the present invention is: the efficient surfactant that the present invention adopts, not only there is higher degreasing efficiency, also there is higher natural degradation effect, overcome the shortcoming that general clean-out system needs just to have cleaning function under middle temperature or comparatively high temps, just have higher cleaning performance at normal temperatures.Solvent acid-basicity is suitable, there is no higher base number, pH value is between 9-11, not containing organic solvent, non-stimulated to skin, not phosphate-containing in auxiliary agent, cleaning waste liquid environmentally safe, corrosion-free to metal body, and owing to having selected water-soluble polymer membrane-forming agent also to have stronger rustless property, overcome the defect that the cleaned rear metal of clean-out system in the past gets rusty easily.
