Description
Technical field
The present invention relates to a kind of solder flux cream for welding, particularly a kind of solder flux cream containing solder, brazing flux, this solder flux cream directly can spread upon welding junction and weld in atmosphere.
Background technology
Tradition solder brazing soldering paste mainly contains two kinds, pure flux paste and pure solder paste, and in conventional welding process, brazing flux and solder are separately coated with and add, and in technique, be therefore often divided into two steps to add, add the step of operation.
In solder brazing field, the soldering paste of institute's extensive use refers to flux paste in fact, and maximum or water base flux paste.Brazing flux powder cannot be suspended in a solvent by water base flux paste uniformly, therefore easily forms precipitation and layering.In the process of manual welding, this point artificially can process and evade, but then more difficult in automation process, especially needing pipeline to transport in the automation process of soldering paste, being unfavorable for the coating of soldering paste, and then affecting the quality of soldering.
In normal solder cream, the specific area of metal solder is little, and degree of oxidation is weak, can realize smooth soldering under brazing flux coordinates.And if make the specific area of granularity at 150-300 object metal dust metal and raise tens times than common solder, metal dust is oxidation by air very easily.Meanwhile, different from solder, the welding temperature of solder brazing is higher, reaches more than 450 degree, and the overwhelming majority is in the scope of 600-1000 degree Celsius.If carry out welding operation in atmosphere, the oxidation that metal occurs is more serious.Therefore traditional braze metal powder cream is all use in the stove having protective atmosphere; such as nitrogen, hydrogen, decomposition ammonia protect metal dust not oxidized; this metal powder cream, at vacuum brazing furnace, has application in tunnel soldering oven, but cannot be used for directly welding in atmosphere.
From describing above, existing soldering paste, due to the defect of self performance, is not suitable for the industrialization automatic welding of solder brazing under air ambient.
Summary of the invention
An object of the present invention is to provide a kind of solder flux cream, object solves prior art problem, provides a kind of solder flux cream simultaneously containing solder, brazing flux, this solder flux cream is suspension, physical property is stablized, and not easily sedimentation layering occurs, can directly weld in atmosphere.
The present invention deal with problems adopt technical scheme be:
Solder flux cream, comprises solder, brazing flux, carrier, and the percentage by weight of each component is, solder 50 ~ 85%, brazing flux 5 ~ 25%, carrier 10 ~ 25%, and the density metal of its soldering paste is 2-12 ton/cubic meter, and granularity reaches 80-400 order, and lotion viscosity is at 50-250pas.
The percentage by weight of each component is preferably, solder 60 ~ 75%, brazing flux 10 ~ 20%, carrier 15 ~ 20%
Described solder is selected from the one in brazing solder, silver-colored brazing solder, nickel-based solder.Its solder can also be other hard solder solders applicatory.
Described brazing flux to be selected from boric acid, borax, potassium fluoborate, potassium fluoride, calcirm-fluoride, sodium fluoride one or more mixing.The selection of brazing flux can also be other hard solder brazing fluxes applicatory.In the present invention, the modal silver-colored brazing flux powder trade mark of main use is FB101 or FB102.
Described carrier is selected from one or more mixing of deodorized kerosine, No. 5 white oils, No. 150 white oils, No. 300 white oils, white oil thickener, hexylene glycol, polyethylene glycol, low molecular polyethylene and spans emulsifying agents.Carrier is for regulating viscosity and the suspended of solder flux cream.
Above-mentioned solder flux cream is by metal dust solder and brazing flux powder Homogeneous phase mixing, brazing flux powder wraps braze metal powder uniformly and prevents it in welding process in air oxidation, it is made to weld in atmosphere, and utilize high activity reduction brazing flux and non-oxidizable organic solvent that is suspended to merge, can prevent solder flux cream from easily layering occurring.
The application that described solder flux cream welds in hardware & tools.
Present stage, often uniformity is high for its welding junction of hardware & tools industry soldering, and joint is less, generally adopt weld tabs to add soldering paste, or the mode that welding wire adds soldering paste carries out soldering, mainly contains weldering three kinds of Type of Welding in flame welding, high-frequency welding and stove.But because existing soldering paste can not weld in atmosphere, therefore these three kinds of welding methods limit and carry out automatic welding to hardware & tools.And solder flux cream of the present invention can weld in atmosphere, automatic welder(welding machine) therefore can be used to weld, simultaneously, because above-mentioned solder flux cream adopts organic solvent as carrier, its suspended is good, not easily layering, and solder, brazing flux need not be added respectively during welding, be conducive to using on automatic welder(welding machine).
Beneficial effect of the present invention:
1. the present invention adopts the mixed uniformly mode of solder soldering paste, coordinates hand-held or automatic some cream machine by solder and soldering paste is disposable is quantitatively directionally applied in welding junction place accurately.Eliminate the inconvenience that solder soldering paste in traditional approach separately adds, while raising the efficiency and ensuring the quality of products, greatly improve the uniformity of welding point, largely avoid waste, less cost, ensure that the clean of working environment.Process ba-sis is laid for realizing automatic welding further.It is the soldering application that the high-quality hardware & tools industry of a kind of clean environment firendly high efficiency uses.
2. this solder flux cream can carry out solder brazing in atmosphere, and particularly flame welding, can realize the automatic welding of solder brazing.
3. this solder flux cream is evenly suspended not stratified, can realize automatic welding.
