Description
Technical field
The present invention relates to tinned copper wire production technical field, be particularly applicable to a kind of tinned copper wire scaling powder and preparation method thereof that production continuous annealing tinned copper wire uses.
Background technology
In electric wire is produced, the most frequently used plating wire is tinned copper wire, and it is mainly used in the conductor wire core of rubber covered mine cable, retardant cable of locomotives and cable for ship etc.Oxidation and the copper wire that after copper wire is zinc-plated, can effectively prevent copper wire directly contact the problems such as the rubber causing is clamminess, copper wire blackening with rubber, improve the weldability of cable service life and core simultaneously.
At present, the production of China's line cable industry tinned copper wire, mainly contain two kinds of modes of chemical plating stannum (electrotinning) and physics zinc-plated (hot tinning), the production technology that the zinc-plated mode of physics is produced tinned copper wire mainly comprises unwrapping wire → annealing → pickling (use scaling powder) → zinc-plated → cooling → draw → add guide shaft oil (minimizing tin ash) → eight flow processs such as take-up.Copper wire annealing has through water cooling rear surface the oxide layer that one deck is very thin, direct zinc-plated meeting causes that zinc-plated copper wire frequently breaks when inhomogeneous, zinc-plated, tinned copper wire leaks the problems such as copper, so enter tin stokehold, must clean with suitable pickle (being scaling powder), to guarantee having good tack between tin layer and copper wire.Can say that pickling directly affects zinc-plated effect and the properties of product of tinned copper wire, be one of tinned copper wire production important step.
The disclosure of the invention of CN1041125A a kind of soldering flux for lead-tin soldering, its component is as follows: rosin 17～23%, stearic acid 17～23%, zinc chloride 13～17%, ammonium chloride 2.5～3.5%, vaseline 31～37%, water 5.5～7.5%.This scaling powder helps weldering poor effect, and contains rosin etc. and human body is had to the material of harm, and the security of use is low.
Summary of the invention
The object of the invention is to overcome the above-mentioned defect that prior art exists, a kind of tinned copper wire scaling powder is provided, it helps weldering property strong; help weldering effective; produce continuously there will not be and leak copper phenomenon, wetting effect is good, and Weldability is strong; postwelding light is mellow and full; scaling powder high temperature easily decomposes, and coordinates air exhauster to use tin stove place non smoke free from extraneous odour, and the coating light of producing the tinned copper wire obtaining is level and smooth; to coating protection, anti-oxidation plays good result.
Another object of the present invention is to provide the preparation method of a kind of tinned copper wire scaling powder.
The technical solution adopted for the present invention to solve the technical problems is: a kind of tinned copper wire scaling powder, by weight percentage, described tinned copper wire is made up of following component with scaling powder: ethylene glycol 0.3-0.6%, triethanolamine 0.3-0.6%, glycerine 0.3-0.6%, dimethylamine hydrochloride 0.05-0.12%, zinc chloride 0-0.6%, ammonium chloride 0.3-0.6%, hydrochloric acid 1.6-2.6%, surplus is water.
Zinc chloride is strong lewis acid, meets water intense hydrolysis, generates complex acid, also can emit hydrogen chloride gas and be pernicious to people, and has corrosivity and toxicity, has dissolution of metals oxide and cellulosic characteristic, can strengthen the bright property of tin plated wire.Dimethylamine hydrochloride activity is high, can reduce surface tension, makes scolder and weld metal mutually moistening, strengthens the weldering ability that helps.Aqueous ammonium chloride solution is faintly acid, acid enhancing when heating.Ferrous metal and other metal are corrosive, larger to copper corrosion especially, therefore contribute to clear up copper wire surface copper powder.Ethylene glycol, triethanolamine and glycerine can strengthen and help weldering effect, and low toxicity, uses safer.
The present invention designs through science, and the tinned copper wire obtaining after rational proportion has following features with scaling powder:
1, help weldering property strong, promote and help weldering effect, produce continuously there will not be and leak copper phenomenon;
2, wetting effect is good, and Weldability is strong, and postwelding light is mellow and full;
3, high temperature easily decomposes, and coordinates air exhauster to use tin stove place non smoke free from extraneous odour;
4, the coating light forming for the production of tinned copper wire is level and smooth, and to the protection of coating, anti-oxidation plays good result.
As preferably, described tinned copper wire is made up of following component with scaling powder: ethylene glycol 0.3-0.6%, triethanolamine 0.3-0.6%, glycerine 0.3-0.6%, dimethylamine hydrochloride 0.05-0.12%, zinc chloride 0.1-0.5%, ammonium chloride 0.3-0.6%, hydrochloric acid 1.6-2.6%, surplus is water.
As preferably, described water is industrial demineralized water.Adopt industrial demineralized water, the weldering effect that helps of the present invention is better.
A preparation method for scaling powder for tinned copper wire, first mixes to obtain compound by ethylene glycol, triethanolamine, glycerine, dimethylamine hydrochloride, zinc chloride and ammonium chloride; In compound, add part water, mix, then add hydrochloric acid, more remaining water is added and mixed, obtain tinned copper wire scaling powder.
As preferably, described in to add part water be the 50-70wt% that adds tinned copper wire scaling powder total water amount.
Because hydrochloric acid is easy to volatilization, therefore, water need to add at twice, first adds the water of tinned copper wire scaling powder total water amount 50-70wt%, then adds hydrochloric acid, is then adding water, and hydrochloric acid is not volatile like this, little to environmental hazard.
The invention has the beneficial effects as follows:
1, help weldering property strong, promote and help weldering effect, produce continuously there will not be and leak copper phenomenon;
2, wetting effect is good, and Weldability is strong, and postwelding light is mellow and full;
3, high temperature easily decomposes, and coordinates air exhauster to use tin stove place non smoke free from extraneous odour;
4, the coating light forming for the production of tinned copper wire is level and smooth, and to the protection of coating, anti-oxidation plays good result.
