Abstract
The invention discloses a kind of environment friendly and pollution-free aluminium soldering silk, the fusion temperature scope of this welding wire is 520-560 DEG C, diameter 1.6-4.0mm; Component by following mass percent forms: potassium fluoride 5-10%, rare earth 5-15%, aluminium 10-25%, silicon 5-15%, bismuth 2-10%, surplus are copper. The all material that aluminium of the present invention uses from solder is environment-friendly materials, meets ROHS standard, has realized zero pollution to environment, and then has protected that operative employee's is healthy; Owing to there is no corrosive material, therefore can save this operation of postwelding pickling, save production cost.
Description
Technical field
The present invention relates to technical field of soldering materials, be specifically related to a kind of environment friendly and pollution-free aluminium soldering silk and preparation work thereofSkill.
Background technology
Along with the enhancing of people's environmental consciousness, environmental regulation day by day improve and strict, although tin-lead solder has excellenceThe advantage such as wetability, weldability, good mechanical property, low melting point and low price, but lead and compound are harmThe harmful and noxious substance of human health and contaminated environment, therefore needs no-lead soft soldering to replace traditional tin in electronics industryKupper solder, particularly along with the lightweight of electronic product, miniaturization, microminiaturized lifting to the quality requirement of electronic product moreStrictly, existing lead-free solder majority is SnAg, SnCu, SnAgCu, SnCuNi.
There are three large unfavorable factors in traditional aluminium soldering:
1) fusing point of aluminium solder, 580 DEG C of left and right, approaches the fusing point (630 DEG C) of mother metal, failure welding rate ratio very muchVery high, actual soldering must be used skilled aluminium weldering skilled worker while production, and production cost is higher.
2) use corrosivity brazing flux, once enter tube interior, easily cause solder corrosion.
3) because soldering brazing flux and solder separate, there is certain difficulty for realizing automatic welding, directly restrictionThe in batches realization of the automation process of scale.
Summary of the invention
Technical problem to be solved by this invention is to provide the pollution-free aluminium soldering silk of a kind of safety, environmental protection.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of environment friendly and pollution-free aluminium soldering silk, the fusion temperature scope of this welding wire is 520-560 DEG C, diameter 1.6-4.0mm; Component by following mass percent forms:
Potassium fluoride 5-10%
Rare earth 5-15%
Aluminium 10-25%
Silicon 5-15%
Bismuth 2-10%
Surplus is copper.
The better quality percentage of each component is:
Potassium fluoride 8%
Rare earth 10%
Aluminium 15%
Silicon 10%
Bismuth 6%
Surplus is copper.
A preparation technology for environment friendly and pollution-free aluminium soldering silk, comprises following processing step:
1) by said ratio configuration raw material, dust, mix, send into smelting furnace and smelt;
2) cooling, hydrostatic profile
3) extruding
4) wire drawing
5) cut off.
The invention has the beneficial effects as follows:
1) alloy system is Al-Si-Bi-Rare Earth quaternary alloy composition, and fusion temperature scope is 530-560 DEG C, canMake the silk material of diameter 1.6-4.0. According to work-hardening capacity difference, silk material diameter is different and change to some extent.
2) all material that aluminium uses from solder is environment-friendly materials, meets ROHS standard, has realized zero dirt to environmentDye, and then protected that operative employee's is healthy. Owing to there is no corrosive material, therefore can save postwelding pickling thisOne operation, has saved production cost.
3) the soldering meeting of general aluminum pipe is used brazing flux, and due to the inhomogeneities that brazing flux is smeared, easily soldering burning, weldingWorkpiece burn-through, causes workpiece to scrap, and this product is due to without brazing flux, has therefore effectively avoided inhomogeneities that brazing flux smearsOccur.
4) realized the two organic unity of solder and brazing flux due to this solder, reduced and smeared this operation of brazing flux, madeAluminium soldering becomes easy realization, and common laborer can carry out high-quality welding through simple training, and owing to being composite woodMaterial can be realized on automatic production line and welding, and has reduced the activity duration, has improved production efficiency.
