Abstract
The invention relates to the technical field of water treatment chemicals and particularly relates to a petroleum sulfonate corrosion inhibitor and a preparation method thereof. The petroleum sulfonate corrosion inhibitor comprises the following components in parts by weight: 10-20 parts of petroleum sulfonate, 10-15 parts of hydroxyethylidene diphosphonic acid, 5-15 parts of barium petroleum sulfonate, 3-8 parts of sodium lignin sulfonate and 60-80 parts of distilled water. The product provided by the invention has good antirusting property and low-temperature dissolubility.
Description
Technical field
The present invention relates to the water treatment agent technical field, especially a kind of sulfonated petro-leum inhibiter and method of manufacture thereof.
Background technology
People are for preventing metallic corrosion, getting rusty in the past, often vegetable and animals oils, MO, lubricated wet goods directly are coated on the metallic surface, and these greases are to stabilized metal, can corroding metal, and they have water, O in certain air-isolation
2Ability, but stop H
2O, O
2Limited in one's ability to metallic surface migration.Someone did experiment, found to be coated with the thick oil-bound film of 5ram in the metallic surface, and the moisture that sees through oil film after 5 days is 0.34～0.45g, and the moisture that sees through the antirust oil film of same thickness has only 0.005～0.008g.In addition, these greases can not stop SO
2, H
2Penetrating of corrosive deposits such as S.Grease itself also can cause metallic corrosion because of oxidation produces free acid.
Summary of the invention
The object of the present invention is to provide a kind of sulfonated petro-leum inhibiter and method of manufacture thereof, mainly solve above-mentioned existing in prior technology technical problem, it has rust-preventing characteristic and dissolution in low temperature property preferably.
For realizing above-mentioned purpose, the present invention realizes like this.
A kind of sulfonated petro-leum inhibiter is characterized in that: it is 10～20 parts of sulfonated petro-leums according to the composition of parts by weight, 10～15 parts of HEDPs, 5～15 parts of barium mahogany sulfonates, 3～8 parts of sodium lignosulfonates, 60～80 parts of zero(ppm) water.
A kind of method of manufacture of aforesaid sulfonated petro-leum inhibiter; It is characterized in that: zero(ppm) water is put in the reaction vessel; Add sulfonated petro-leum, HEDP, barium mahogany sulfonate, sodium lignosulfonate in the reaction vessel successively then; After stirring, get product.
The advantage that prescription of the present invention and method can embody is:
1, employed HEDP in the disclosed a kind of sulfonated petro-leum inhibiter of the present invention, it can form stable complex compound with multiple metals ions such as iron, copper, zinc, can the surperficial oxide compound of dissolution of metals.Can belong to ion with underwater gold, especially calcium ion forms six annulus inner complexs, and tool is scale inhibition effect and the significantly molten limit effect of tool preferably.
2, employed sodium lignosulfonate is to heavy metal in the disclosed a kind of sulfonated petro-leum inhibiter of the present invention, and especially iron, copper, stannous ion have sequestering power preferably, play corrosion inhibition.
3, employed barium mahogany sulfonate has good anti-embroidery, antiseptic property to ferrous metal, non-ferrous metal copper and alloy thereof in the disclosed a kind of sulfonated petro-leum inhibiter of the present invention, and oil soluble is good.
4, in use it has rust-preventing characteristic and dissolution in low temperature property preferably to the disclosed a kind of sulfonated petro-leum inhibiter of the present invention.
Embodiment
Embodiment 1: 60 parts of zero(ppm) water are put in the reaction vessel, then 10 parts of sulfonated petro-leums, 10 parts of HEDPs, 5 parts of barium mahogany sulfonates, 3 parts of sodium lignosulfonates are added in the reaction vessel successively, after stirring, get product.
Embodiment 2: 70 parts of zero(ppm) water are put in the reaction vessel, then 15 parts of sulfonated petro-leums, 12 parts of HEDPs, 10 parts of barium mahogany sulfonates, 5 parts of sodium lignosulfonates are added in the reaction vessel successively, after stirring, get product.
Embodiment 3: 80 parts of zero(ppm) water are put in the reaction vessel, then 20 parts of sulfonated petro-leums, 15 parts of HEDPs, 15 parts of barium mahogany sulfonates, 8 parts of sodium lignosulfonates are added in the reaction vessel successively, after stirring, get product.
Being merely preferred embodiment of the present invention in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should be technological category of the present invention.
