Background technology
Engineering machinery is the important component of equipment manufacturing industry.Put it briefly, all restoration in earth-rock construction engineerings, pavement construction with
Machinery dress necessary to comprehensive mechanized construction engineering needed for maintenance, the operation of flow-type lift and various architectural engineerings
It is standby, referred to as engineering machinery.It necessarily can't do without the use of steel, existing process for machining and manufacturing in the processing and manufacturing of engineering machinery
In, more there is steel and metal or the nonmetallic form bonded by resin binder, and in order to lift such adhesive form
Stability in use, it is necessary to strengthen the cohesive force between two workpiece, and the method for lifting cohesive force has the spy of lifting resin binder
Property, improve surface bonding characteristic of resin binder and steel, metal, nonmetallic etc. etc., paying attention to resin people at present more and gluing
The performance improvement of mixture, and the research to the latter is less.
The content of the invention
The purpose of the present invention is to be directed to the problem of existing, there is provided a kind of phosphorization treatment process of steel plate.
The present invention is achieved by the following technical solutions：
A kind of phosphorization treatment process of steel plate, comprises the following steps：
（1）Bead：
After surface chemistry oil removing, clear water flushing, draining drying process are first carried out to pending steel plate, then put it into shot-peening
It is standby to being taken out after steel plate progress bead in machine；
（2）Freezing processing：
To step（1）Move to be put into freezer again after one layer of antirust solution of surface of steel plate atomized spray after processing and carry out freezing processing,
It is -5 ~ -8 DEG C to keep cryogenic temperature, is taken out after 3 ~ 4h of freezing processing standby；
（3）Phosphorating treatment：
By step（2）Steel plate after processing, which is immersed in etching solution, carries out phosphorating treatment, controls phosphorating treatment during phosphatization
The temperature of liquid is 13 ~ 15 DEG C, is taken out after 20 ~ 25min of phosphorating treatment standby；
（4）Drying process：
With deionized water to step（3）After steel plate after processing rinses once, then put it into drying box and place is dried
Reason, after the completion of take out.
Further, step（1）Described in electrochemical deoiling using acetone carry out oil removing.
Further, step（1）Described in bead when blasting media be diamond dust, its granularity is 80 mesh, spray
The pressure of compressed air is 0.75 ~ 0.8MPa during sand, and the distance of sandblasting is 90 ~ 100mm, and the angle control of sandblasting is 90 °.
Further, step（2）Described in antirust solution be antirust agent and water according to mass ratio 1：30 ~ 35 mixed and
Into.
Further, step（3）Described in etching solution in each composition and its corresponding content be：Sodium dihydrogen phosphate 30
~ 35g/L, phosphatase 79 ~ 12ml/L, 3 ~ 6g/L of sodium nitrate, 1 ~ 2g/L of tartaric acid, 0.5 ~ 1g/L of citric acid, 0.5 ~ 1.5g/L of phytic acid,
Surplus is water.
Further, step（4）Described in drying process temperature be 80 ~ 85 DEG C.
Improve steel surface characteristic, it is adhesion strength between enhancing workpiece to lift its bonding characteristic between adhesive interface
One of direction, also there is the processing method improved to steel surface characteristic at present, but mode is more single, and the effect of processing is still
It is unsatisfactory, special optimization has been carried out again to the process of surface treatment of steel on the basis of a large amount of practices to this present invention
Improve, wherein first having carried out bead to steel, substantial amounts of miniature pit is formd on the surface of steel, is follow-up behaviour
Lay a good foundation, and carried out freezing processing, specifically first with antirust solution be sprayed on steel surface then carry out it is cold
Freeze, now antirust solution is filled with pit tissue caused by shot-peening, and is fixedly attached on surface of steel plate, antirust solution quilt during freezing
Freezing is in solid-state, is laid the foundation for follow-up phosphorating treatment, has finally carried out phosphorating treatment, the steel plate after freezing is direct plungeed into
Into etching solution, the solid-state antirust solution of the surface of steel plate thaw by outer surface, the table of the steel after bead
Face projection thaws from solid-state antirust solution at first, raised with this by etching solution phosphating reaction, the phosphate of formation immediately
Deposit and be nucleated for attachment point, form the phosphating coat of radial distribution, with the progress that solid-state antirust solution thaws, phosphating coat not medium well
Come into drawout, after solid-state antirust solution complete thaw, phosphorating treatment process is almost completed, because continuous by solid-state antirust solution
The influence of defrosting dissolution, it can not deposit to form phosphating coat in the pit bottom of steel surface, namely the lower floor of phosphating coat can have
Substantial amounts of miniature pit, phosphating coat have the function that capillary in itself, can promote penetrating down into for resin binder, and deposition is fixed
In the pit under phosphating coat, the contact area and bonding dynamics of resin binder and steel surface are improved, so as to improve
The adhesion characteristic of steel.
The present invention has advantages below compared with prior art：
The present invention has carried out special phosphorating treatment to steel plate, effectively improves the phosphatization institutional framework of surface of steel plate, improves
Its bonding characteristic with resin binder, has good value for applications.
