Description
Technical field
The present invention relates to metal processing sectors, more particularly to a kind of copper bar antioxidant and its application method.
Background technology
It is increasing to the demand of electric wire product with the development of electrical industry, while to the requirement of its quality
Also improve therewith, it is necessary to using high-purity, highly conductive, the moulding good copper conductor of processing.
Updraft continuous casting process is the main production for producing electric wire oxygen-free copper-wire base, in southern plum rain season,
There was dampness in the air, and continuous up-casting copper bar easily aoxidizes, and have impact on its using effect.
Patent 201310278163.1 discloses a kind of suitable packfong high temperature-proof colour-changing agent and its application method, and it is solved
Determine the non-environmental protection and high temperature failure problem of traditional anti-blushing agent, but it is not particularly suited for drawing for packfong
Continuous casting copper bar.
The content of the invention
For existing technical problem, the present invention provides a kind of copper bar antioxidant and its application method, can solved
Draw the problem of oxidation of continuous casting copper bar.
To achieve the above object, the technical solution used in the present invention is：Antioxidant include following percentage by weight into
Point：50 ~ 500ppm of aphthotriazoles, 50 ~ 500ppm of BTA, 50 ~ 500ppm of mercaptobenzothiazoler, methyl benzotriazazole
50 ~ 500ppm, 10 ~ 100ppm of sodium phosphate, 10 ~ 100ppm of sodium molybdate, 10 ~ 100ppm of sodium metasilicate, 10 ~ 100ppm of sodium tungstate, mountain
10 ~ 100ppm of potassium sorbate, ethanol 50 ~ 60%, surplus are deionized water.
After aphthotriazoles, BTA processing, surface assembles chain structure by one layer and covered on copper bar surface,
Play a part of protection purifying.
Mercaptobenzothiazoler can act synergistically with aphthotriazoles, BTA, play more preferable protecting effect.
Aphthotriazoles, BTA be by forming the oxidation that complex compound film prevents copper with the Cu+ on copper surface, this film-strength is big,
Compactness is good, has excellent protective effect, but its film forming speed is slow, if imperfect, can cause local loss.Sulfydryl
Benzothiazole is to prevent oxidation by directly adsorbing in copper liquid surface, and adsorption rate is fast, will not cause local losses, when sulfydryl benzene
And thiazole and aphthotriazoles, BTA, when co-existing in a system, can mutually promote interface interaction, form polynary protection
Film, produce good cooperative effect.
Methyl benzotriazazole more nonpolar methyl on molecular structure than BTA, can form single point
The hydrophobicity of sublayer film is more preferable, and the presence of methyl does not interfere with to the reaction between substrate molecule and copper.
Potassium sorbate can be by forming cuprous oxide, Kocide SD and Cu with copper（Ⅱ）The composite bed of-sorbate,
Copper can be played a protective role.
Sodium phosphate, sodium molybdate, sodium metasilicate are as good cosolvent.
Described aphthotriazoles, BTA, mercaptobenzothiazoler, the component ratio of methyl benzotriazazole are 1：1：
1：1.
Described sodium phosphate, sodium molybdate, sodium metasilicate, sodium tungstate, the component ratio of potassium sorbate are 1：1：1：2：2.
Application method of the present invention：Continuous up-casting copper bar extracts from crystallizer, by draw-gear, copper bar table
There is 70 ~ 90 DEG C of residual temperature in face, and antioxidant is uniformly dripped and pours copper bar surface, is then again rolled up copper bar by take-up
Take.
Described drop leaching speed is 30 ~ 60 drops/min.
The beneficial effect of technical scheme provided by the invention：
1. aphthotriazoles, BTA, mercaptobenzothiazoler, methyl benzotriazazole, sodium phosphate, sodium molybdate, sodium metasilicate,
Sodium tungstate, potassium sorbate etc. mutually cooperate with, and reach good oxidation-protective effect.
2. using the residual temperature on continuous up-casting copper bar surface, antioxidant is set preferably to play oxygen in the range of 70 ~ 90 DEG C
Change acts on.
3. the antioxidant cost selected is low, easy to operate, meet the industrialization production of continuous up-casting copper bar.
Specific embodiment
Example 1
Antioxidant includes following weight percent composition：Aphthotriazoles 200ppm, BTA 200ppm, sulfydryl benzo thiophene
Azoles 200ppm, methyl benzotriazazole 200ppm, sodium phosphate 50ppm, sodium molybdate 50ppm, sodium metasilicate 50ppm, sodium tungstate
100ppm, potassium sorbate 100ppm, ethanol 50%, surplus are deionized water.
Continuous up-casting copper bar extracts from crystallizer, and by draw-gear, there is 75 DEG C of residual temperature on copper bar surface, will be anti-oxidation
Uniformly drop pours copper bar surface for agent, and drop leaching speed is 50 drops/min, is then again batched copper bar by take-up.
