Abstract
The present invention relates to an antirust metal cutting fluid from polyaniline, which belongs to the field of metal cutting fluids. The present invention is prepared from the following components (wt. %): 25 to 30 portions of polyaniline water nature preservative agent, 15 to 20 portions of triethanolmine, 45 to 55 portions of polyvinyl chloride latex, 2 to 3 portions of polyether glycol and 15 to 40 of water. The present invention greatly improves the corrosion resistant properties of products. The present invention is used for the relief of oil, the production of gas wells, and metal corrosion during pipeline transportation processes. The present invention has the advantage that polyaniline is used as a corrosion resistant additive which dissolves in a cutting fluid for improving the rust prevention function and the corrosion resistance function of the metal cutting fluid.
Description
Technical field
The invention belongs to the metal working fluid field.
Background technology
When metallic substance by giving the set pattern lattice when cutting, be the mill sassafras between minimizing instrument and the workpiece, increase oilness and take away the heat that produces because of the mill sassafras, need and be cut at instrument and inject metalworking coolant between the metallic substance, be called for short cutting fluid.Cutting fluid also should have good Corrosion Protection except that above-mentioned functions, to guarantee the workpiece cleaning, not have the erosion of embroidery.Cutting fluid is the companion in the process of metal working, is again the meson that very easily causes metallic corrosion simultaneously.The cutting fluid that present China uses in process of metal working has two big classes, promptly water-insoluble metal working fluid and water-soluble metal cutting fluid.In these two kinds of cutting fluids, for improving the rustless property of product, dosed the organic anti-corrosive agent mostly, and acidifying takes place and goes bad in the organic anti-corrosive compound under high-temperature condition, recycle and can not guarantee its antiseptic property.
Summary of the invention
The invention provides a kind of polyaniline anti-rust metal cutting fluid, to solve the bad problem of metal current cutting fluid rustless property.The technical scheme that the present invention takes is: be made up of the component by following weight part:
25～30 parts of polyaniline aqueous sanitass
15～20 parts of trolamines
45～55 parts of polyvinylchloride latexs
2～3 parts of polyether glycols
15～40 parts in water
The preferred embodiment of the present invention is: be made up of the component by following weight part:
29.5 parts of polyaniline aqueous sanitass
18 parts of trolamines
50 parts of polyvinylchloride latexs
2.5 parts of polyether glycols
20 parts in water
The invention has the advantages that first polyaniline to mix with cutting fluid, improve the anti-embroidery erosion function of metal working fluid as anticorrosion compound.This rust preventive cutting fluid has special anticorrosion mechanism, it is generally acknowledged that polyaniline has certain redox potential, and it makes the surface of iron and steel that oxidation take place, and reaches the passivation potential of iron, makes the Fe of surface generation one deck densification of iron
3O
4Zone of oxidation has stoped the further oxidation of iron.In order to solve the preservative effect problem that cutting fluid recycles for a long time, we have proposed polyaniline to dissolve in the cutting fluid as anticorrosion compound first, thereby have effectively prevented organic anti-corrosive agent acidifying and the etching problem that brings, have improved quality product.Simultaneously, because this rust preventive cutting fluid remains in the metallic surface, the turnover staging life after the metal process segment is finished, anticorrosionly get rusty after extending to 30 days, save secondary and smeared anticorrosion greasy technology, reduced production cost, solved a corrosion difficult problem.
Physical and chemical index of the present invention: outward appearance: black liquor, pH value: 8.2-9.5 (3% distilled water diluting) density: 0.96-1.2, corrosion experiment: experiment method: SH/T0080, copper sheet, 45
#Steel disc: 100 ℃/24h, qualified.Damp and hot experiment: experiment method: GB/T2361, copper sheet, 45
#Steel disc: 25d is qualified.
