Abstract
The invention relates to a novel cold-rolled steel sheet passivating agent. The novel cold-rolled steel sheet passivating agent is prepared from, by weight, 3.5 parts of 2-hydroxyethyl-1-tin sulfoacid, 5 parts of tetramethylethylenediamine, 4.2 parts of tri-nickel sulfate amine sodium phosphate, 1.2 parts of zinc nitrate, 3 parts of sodium hypochlorite, 8 parts of bentonite, 0.08 part of strontium chloride, 42 parts of phosphoric acid with the mass fraction of 80%, and 15 parts of water. The novel cold-rolled steel sheet passivating agent is easy to use, the passivating effect is improved, passivating is more uniform, the compactness of a passvated layer is high, and the anti-corrosion capacity of stainless steel can be greatly improved; in addition, a surface can be protected against oil dirt, and the dirt resistance and the fingerprint pressing resistance of the surface of the stainless steel are improved; meanwhile, a treatment method using the passivating agent is simple, low in energy consumption, high in treatment agent utilization rate, and free of pollution.
Description
Technical field
The invention belongs to metal conditioner field, be specifically related to a kind of Novel cold-rolled steel plate passivator.
Background technology
Cold-reduced sheet has good performance, namely by cold rolling, thickness is thinner, precision is higher cold rolled strip and steel plate can be obtained, planeness is high, surface smoothness is high, cold-reduced sheet surface cleaning light, be easy to carry out coating processing, wide in variety, purposes is wide, there is punching performance high and not timeliness, feature that yield-point is low simultaneously, so cold-reduced sheet tool purposes widely, be mainly used in automobile, print the industries such as metal bucket, building, building materials, bike, still produce the best selection of steel plate with organic coating simultaneously.
After stainless steel cold-rolled plate machines, need to carry out surface treatment, promote non-corrosibility and the surface stability of cold-reduced sheet.
Summary of the invention
The object of this invention is to provide a kind of Novel cold-rolled steel plate passivator, improve Stainless Steel Watch face stability and erosion resistance.
The present invention is achieved through the following technical solutions:
A kind of Novel cold-rolled steel plate passivator, is formed by following preparation of raw material: 3.5 parts, 2-hydroxyethyl-1-sulfonic acid tin, Tetramethyl Ethylene Diamine 5 parts, three single nickel salt amine sodium phosphates 4.2 parts, zinc nitrate 1.2 parts, clorox 3 parts, wilkinite 8 parts, strontium chloride 0.08 part, the phosphatase 24 2 parts of massfraction 80%, 15 parts, water by weight.
Beneficial effect of the present invention: Novel cold-rolled steel plate passivator provided by the invention uses simple, improve passivation effect, make passivation evenly, passivation layer density is high, can greatly improve stainless anti-corrosion capability, and surface can oil-stain-preventing, improve antifouling, the anti-fingerprint pressing ability of stainless steel surface, use the method for passivator process of the present invention simple simultaneously, energy consumption is low, and disposal methods agent utilization ratio of the present invention is high, pollution-free.
Embodiment
A kind of Novel cold-rolled steel plate passivator, is formed by following preparation of raw material: 3.5 parts, 2-hydroxyethyl-1-sulfonic acid tin, Tetramethyl Ethylene Diamine 5 parts, three single nickel salt amine sodium phosphates 4.2 parts, zinc nitrate 1.2 parts, clorox 3 parts, wilkinite 8 parts, strontium chloride 0.08 part, the phosphatase 24 2 parts of massfraction 80%, 15 parts, water by weight.
The present invention uses cesium chloride to add, and greatly improves compactness and the stability of Passivation Treatment, and use passivator process steel plate 1h of the present invention, after measured, surface of steel plate is without the space of non-passivation.Use wilkinite to improve dispersion effect, strengthen the contact of passivator and steel plate, promote passivation effect, make passivation layer finer and close, and passivator process post passivation layer stability is high, hardness is also higher.
Use following methods to carry out Passivation Treatment, comprise the following steps:
Cold-rolled steel sheet is cleaned up, dry, then passivator is used to carry out Passivation Treatment, Passivation Treatment temperature is 55-58 DEG C, the Passivation Treatment time is 20-25s, and passivator is formed by following preparation of raw material by weight: 3.5 parts, 2-hydroxyethyl-1-sulfonic acid tin, Tetramethyl Ethylene Diamine 5 parts, three single nickel salt amine sodium phosphates 4.2 parts, zinc nitrate 1.2 parts, clorox 3 parts, wilkinite 8 parts, strontium chloride 0.08 part, the phosphatase 24 2 parts of massfraction 80%, 15 parts, water.
Use process passivator of the present invention process 301 stainless steel plate, use the display of Bluepoint test result qualified.
Use neutral salt spray test, salt fog temperature 35 DEG C, brine concentration is 50g/L, and during process, pressure is 0.025MPa, and process 195h stainless steel surface starts to occur corrosion.
Use acetic acid salt spray test, treatment temp 35 DEG C, brine concentration is 50g/L, adds Glacial acetic acid, regulates and makes its PH be 3, and process 102h stainless steel surface starts to occur corrosion.
Result proves, the stainless steel surface good corrosion resistance after process of the present invention.
Make to press with finger stainless steel surface, substantially without fingerprint residues, and after process, the wear resistance of stainless steel surface also improves greatly.
Above-mentioned 301 stainless steel plates handled well are put into Cupric Chloride Solution, and 38 DEG C of process 3h, interval 8h, again process 3h, circulate 3 times, stainless steel surface is separated out without copper, proves without leak source.
Use passivator process 304 stainless steel plate of the present invention, use the display of Bluepoint test result qualified.
Use neutral salt spray test, salt fog temperature 35 DEG C, brine concentration is 50g/L, and during process, pressure is 0.025MPa, and process 201h stainless steel surface starts to occur corrosion.
Use acetic acid salt spray test, treatment temp 35 DEG C, brine concentration is 50g/L, adds Glacial acetic acid, regulates and makes its PH be 3, and process 98h stainless steel surface starts to occur corrosion.
Result proves, the stainless steel surface good corrosion resistance after process of the present invention.
Make to press with finger stainless steel surface, without fingerprint residues, after process, the wear resistance of stainless steel surface also improves greatly.
Above-mentioned 304 stainless steel plates handled well are put into Cupric Chloride Solution, and 38 DEG C of process 20h, stainless steel surface is separated out without copper.
Passivator proportioning of the present invention reaches optimum value through repetition test, passivation effect can be caused not reach effect of the present invention after change passivator proportioning, parameter.
