Description
Technical field
The present invention relates to a kind of phosphorization technology more particularly to a kind of sides of efficient rubber tyre iron wire phosphatization antirust technology
Method.
Background technique
Phosphorating treatment is that metal surface (mainly steel) is nonmetallic, non-conductive by one layer of chemical reaction generation
, porous phosphate film.Using conventional phosphatizing liquid processing workpiece, energy consumption is high, the time is long.For large-scale workpiece, pass
The higher cost that phosphorating treatment of uniting needs, and the time to form a film is long, forms a film loose, film forming thickness is uneven, and hardness is not high, table
Face is not clean, and corrosion resistance is poor, is especially unsuitable for the phosphatization of the secret workpiece such as gear.Tire, can be in rubber in order to enhance toughness
Iron wire is added and plays the role of support, iron wire and water, air contact get rusty easily, and rusty part is easily broken off or divides with rubber
Iron wire from, separation, fracture is easy to poke tire and causes accident, therefore carrying out phosphatization to the iron wire in insertion tire is that one kind has
Imitate the method for preventing tire accident.And the iron wire after phosphatization can decrease with rubber conjugation, in order to solve this problem, I
Used the hydrophilic radical combination iron wire of coupling agent and lipophilic group and rubber are effectively combined.With patent
CN201210001427 the difference is that raw material is simply at low cost, behind use coupling agent treatment, it is more preferable with rubber conjugation.
With patent CN200710157983 the difference is that a variety of phosphating solutions provided, have zinc system, calcium system etc., and reaction process is not required to
Want catalyst, rapid reaction, simple process.With patent CN201010248086 the difference is that formula and simple process, original
Material is easy to get, is low in cost, and treatment effect is more preferable.
Summary of the invention
It is an object of that present invention to provide a kind of antirust technology of effective tire iron wire, can effectively make to make in tire
The abundant phosphatization of iron wire, and can with rubber is stable is combined together, prevent iron wire from getting rusty, prolong the service life of tire
It is long.
A kind of method of rubber tyre iron wire phosphatization antirust technology, it is characterised in that:
(1) there are greasy dirts, cleaning process alcoholic solution to carry out first time cleaning on iron wire surface, and cleaning way is sonic oscillation
Cleaning, scavenging period 15min；
(2) part greasy dirt is still remained after iron wire is cleaned using organic solvent, needs further alkali cleaning, and cleaning way is super
Sound oscillation cleaning, scavenging period 15min；
(3) it after iron wire surface and oil contaminant cleans up, is cleaned and is dried with distilled water, iron wire is put into bonderite and carries out phosphorus
Change, phosphatization mode is static dip phosphatizing, time 30min；
(4) iron wire phosphatization rear surface can generate a large amount of bubbles, prevent phosphatization and will affect the stabilization of phosphate coating, therefore phosphorus
It needs for iron wire to be put into immersion 10min in defrother after the completion of changing and removes bubble removing；
(5) iron wire surface needs for iron wire to be added quiet in oxidizing agent solution because bubble has part without complete phosphatization
Only impregnate 15min.The non-phosphatization part in its surface is set to be oxidized to form dense oxidation film；
(6) the iron wire cleaning after aoxidizing is dried is smeared with coupling agent solution, it is made to form one layer of parent close to iron wire side
Aqueous group and iron wire surface bonding form one layer of lipophilic group on the outside of iron wire, enable its in the rubber for being embedded in tire when
It is enough more preferably to be combined with rubber.The process of dipping coupling agent can be direct smearing, static can also impregnate.
Organic solution of present invention used in the process of iron wire cleans greasy dirt, can be alcoholic solution, petroleum ether solution, third
Ketone solution, carbon tetrachloride solution, chloroform etc. or any two kinds of mixture.
Present invention lye used in the process of iron wire cleans greasy dirt can be the NaOH solution of concentration 0.1mol/L-1mol/L
Or KOH solution.

Cr (the NO of 0.5mol/L not can be used by phosphatization part for iron wire in the present invention3)3Solution also can be used identical dense
The KMnO of degree4Solution is aoxidized, and dense oxidation film is formed.
In order to preferably in conjunction with rubber, need to smear one layer of coupling agent on surface after iron wire phosphatization in the present invention,
Wherein coupling agent can be the ethanol solution or 3- aminopropyl dimethylamino silane ethanol solution of trimethyl phenyl silane
Deng.Its concentration is 1%-2% (volume).
The mode of iron wire dipping coupling agent can be static dipping in the present invention, coupling agent can also be heated to 50-100
It is impregnated after DEG C, dip time 10-30min.
The present invention is using the one of which in the organic solutions such as alcohol, petroleum ether, chloroform, carbon tetrachloride or centainly
Ratio mixing solution to will phosphatization iron wire carry out surface clean to degrease.Using NaOH solution to the iron cleaned
Silk further cleaning, guarantees that iron wire surface cleaning is bright.Use Ca (H2PO4)2Solution, Zn (H2PO4)2Solution or both presses one
The mixed solution or and MnSO that certainty ratio is constituted4The mixed solution that solution is constituted by a certain percentage carries out immersion phosphorus to iron wire
Change, KNO is added in immersion after a certain period of time2Solution or KNO2With KNO3The solution being mixed in a certain ratio removes blibbing,
Guarantee complete phosphatization.It is dried after phosphatization, then uses Cr (NO3)3Solution immersion makes the complete iron wire of non-phosphatization form dense oxide
Film and phosphating coat play the role of protecting iron wire jointly.It completes that iron wire is immersed 3- aminopropyl dimethylamino silane second after this step
The coupling agents such as ethyl alcohol of alcoholic solution, trimethyl phenyl silane, make it form one layer of hydrophilic radical on iron wire surface, and outside
Side forms one layer of lipophilic group, guarantee its can with rubber tyre is even closer is combined together.
