Abstract
The invention discloses an acid pickling inhibitor in a steel wire acid pickling solution, which comprises any one or two or three of phenylthiocarbamide, ammonium bifluoride and tributyl phosphate. The acid pickling inhibitor accounts for 0.008-0.4 wt% of the hydrochloric acid pickling solution. When being used for performing acid pickling on steel wires, the acid pickling solution prepared from the acid pickling inhibitor and hydrochloric acid can decelerate the corrosion of the hydrochloric acid on the steel wire matrix in the acid pickling process, inhibit the hydrogen absorption capacity of the steel wire, effectively avoid the hydrogen brittleness phenomenon of the steel wire and enhance the utilization ratio of the acid pickling solution; the steel wire subjected to acid pickling has stable mechanical strength; and after being subjected to chemical plating, the steel wire has higher adhesive force with rubber and higher rubber adhesion rate.
Description
Technical field
The present invention relates to steel bead wire plating front surface treatment process, relate in particular to a kind of hydrochloric acid that can slow down in acid cleaning process and the burn into of steel wire matrix is suppressed to steel wire hydrogen-absorbing ability effectively avoid steel wire that the restrainer of " hydrogen embrittlement " occurs.
Background technology
In industrial production, for the removal of steel material surface oxide skin, often adopt the acidic cleaning solution that corrodibility is stronger, the mode such as example hydrochloric acid is washed, electrolysis sulfuric acid is washed, chemical sulfuric acid is washed.These pickle solutions, in the process of cleaning material surface scale, tend to the matrix of material to cause certain corrosion, affect the performance of material itself, have also caused the excessive waste of material and pickle solution; Meanwhile, in these acid cleaning process, the hydrogen that pickling produces can produce " hydrogen embrittlement " phenomenon to steel wire matrix permeability, affects mechanical strength.
Along with the development of automotive light weight technology, high speed, as the radial of automobile important component part, with advantages such as its high speed, energy-saving, lightweight, actual service life length, obtain application and development rapidly.Radial in use will bear stretching, compression, torsion and the reactive force such as centrifugal, and as the steel bead wire of one of framework material, the quality of quality directly affects the quality of tire.Conventional steel bead wire is that a kind of tinning bronze is as the steel wire at fortified tyre edge at present.Tyre bead is the Steel Traveler being compiled into by steel bead wire and squeegee, and cover tire is closely stabilized on tyre bead.During automobilism, tire bead and tyre bead edge are stressed very large, if form the framework material steel bead wire of tyre bead and the bounding force of rubber not high, very easily cause tyre bead loose and make tyre break, security incident occurs, thereby Production for Steel Wire producer and tire enterprise are all paid much attention to this problem.In actual use, the height of the bounding force of steel wire and rubber, is directly connected to the quality of tire quality.In steel bead wire production process, steel bead wire surface-brightening will cause bounding force very low, and the sizing material that Steel Wire Surface is adhered to when being wound around tyre bead is less, and common intermittently kiss-coating not, directly expose the situation that existing Steel Wire Surface has not a particle of youngster's sizing material.State Intellectual Property Office discloses the production method of the bonding tin bronze tempered bead wire of mono-kind of CN102586787A and rubber height, comprise the steps: 1., choose diameter range at the steel wire of 0.70-2.60mm, 2., steel wire by step in is 1. by the lead of melting, tin, bismuth, lead alloy, tin alloy, any one single solution in bismuth alloy solution or carry out tempering by the mixing solutions of two or more the single solution composition in them, 3., the steel wire that step is obtained in 2. rinses through water, through electrolytic pickling, on its surface, form again sags and crests, wash again, 4., the surface that utilizes chemical replacement method to obtain in 3. in step is covered with the copper coating tin alloy coat of the steel wire of sags and crests, 5., the coating wire that step is obtained in is 4. washed, dry, 6., 5. the antirust tackifier coating of coating wire surface-coated obtaining in step, 7., take-up, obtain the tin bronze tempered bead wire with rubber adhesion intensity >=1100N/50cm.
In the production technology of current conventional steel bead wire, before electroless plating, the mode of the electrolytic pickling conventionally adopting, electrolytic pickling easily makes the steel bead wire of high-carbon content that " hydrogen embrittlement " occurs, and affects the work-ing life of steel bead wire; Meanwhile, conventional plating pre-treating process also easily makes Steel Wire Surface occur the phenomenon that concavo-convex degree is inhomogeneous, affects subsequent plating layer quality, reduces the bond properties of steel bead wire and rubber.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of and can slow down hydrochloric acid in acid cleaning process and the burn into of steel wire matrix is suppressed to steel wire hydrogen-absorbing ability effectively avoid steel wire that the restrainer of " hydrogen embrittlement " occurs.
The present invention is achieved by the following technical solution:
For the restrainer of steel wire pickle solution, comprise in benzene thiocarbamide, ammonium bifluoride, tributyl phosphate any one or by two or three in them, formed, its mass percent in hydrochloric acid pickler is 0.008-0.4%.
It is particularly useful for steel bead wire plating pre-treatment.
The present invention compared with prior art has following beneficial effect:
The present invention and hydrochloric acid preparation form after pickle solution, steel wire is carried out to pickling, can slow down hydrochloric acid in acid cleaning process effectively avoids steel wire that " hydrogen embrittlement " phenomenon occurs to the burn into inhibition steel wire hydrogen-absorbing ability of steel wire matrix, improve the utilization ratio of pickle solution, after pickling, the physical strength of steel wire is stable, after changing plating, the bounding force of steel wire and rubber, binding efficiency are all higher.
