Description
Technical field
The invention belongs to welding technology field, it is related to a kind of ingredient of ABS type sticky brazing filler material and prepares forming method, and infuses
Its welding procedure is illustrated.
Background technique
Solder be two kinds of materials bonding gap in or gap by added by filler, solder mainly with powdery, filiform,
The modes such as strip, sheet are supplied, wherein carrying out welding using weld tabs, oxidation area is small when having welding, and postwelding attractive appearance is used
Material is uniformly, less to there is the advantages that lacking weldering and solder skip, but the production of weld tabs needs metal solder to have certain ductility, wherein
Gold, silver, copper-based metal ductility are preferable, can roll as foil, but high temperature sticky brazing filler material is added to reduce fusing point
The alloying elements such as Si, Mn, B, P, so that the brittleness of material becomes larger, so as to cause Foil strip rolling process easy fracture；This adhesive tape pricker
Material can only prepare powdering during use or paste uses.
Soldering paste or welding powder all have the shortcomings that be difficult to smear uniformly, welding efficiency it is lower under, in contrast, sticky brazing filler material
Welding point is smooth, and welding performance is stablized, and strength of welded joint error is small.Therefore, solder powder is processed into soft adhesive tape
Solder can guarantee its in the uniform coating of piece surface solder, part or rock-candy structure table that can effectively to some complexity
Face carries out more accurate welding.Presently commercially available sticky brazing filler material uses methylene chloride, and the irritations solvent such as chloroform is right
Environment and people's health have certain harm, and when in use, and traditional sticky brazing filler material surface viscosity is inadequate, and it is accurate right to need
Level is set, and is otherwise easily put askew or is folded, causes welding defect.
It is using polymethyl methacrylate, methyl methacrylate in CN1580170A " production sticky brazing filler material binder "
Ester and dibutyl phthalate make binder, methylene chloride, and chloroform makees solvent, and the sticky brazing filler material surface of synthesis is smooth viscous
Spend it is low, easily cause sticky brazing filler material weld shift, need fixture to fix, furthermore its solvent have toxicity.
CN106141508 " a kind of high temperature sticky brazing filler material preparation facilities and method " use a set of continuous preparation facilities into
The production method of row sticky brazing filler material, easy industrialized production, but process is relatively complicated.The dosage of sticky brazing filler material is less, and not big
Scale uses.
Summary of the invention
Present invention mainly solves the technical issues of be that it is simple and easy to control to provide a kind of technical process for existing sticky brazing filler material
It makes, the more environmentally-friendly method of solvent, product viscosity made from this method is bigger, and convenient for welding, and the holding time is more permanent.
In order to solve the above technical problems, the scheme that the present invention uses is a kind of ABS type sticky brazing filler material and preparation method thereof,
It is characterized in that, method includes the following steps:
1. the preparation of binder
Binder each component includes being pre-dissolved solvent acetone, binder ABS resin, and toughener dibutyl phthalate is main
Solvent acetic acid butyl ester, weight percent are as follows:
Solution heating water bath is removed into acetone, and is sealed after supplementing butyl acetate in right amount.
2. the preparation of sticky brazing filler material
Gained after sticky brazing filler material is dried after mixing by superalloy powder and binder, wherein alloy powder and bonding
The weight percent of agent is
Binder 8-15%
Alloy powder 85-92%
The organic binder powder of the alloy powder of 85-92% mass and 8-15% mass is mixed and stirred for uniformly, it will
Obtain solder mixture to be put into baking oven, be dried to solder in pureed, obtained pureed solder is put into milling train, multiple rolling into
Binder is uniformly mixed by one step with metal solder powder, and removes bubble.When solder color is uniform and surfacing Shi Keting
Only roller is pricked.
The solder rolled is twisted into strip and is placed on progress roller bundle on masking foil, rolling spacing is adjusted, is initiated with 2mm, rolls every time
The complete back roller hypotelorism 0.05mm of roller repeats roll, and final roll width is predetermined sticky brazing filler material thickness and masking foil thickness
The sum of (0.2mm).After being made by cutting strip is made in product.
3. the welding procedure of sticky brazing filler material
ABS type sticky brazing filler material is cut into the shape being consistent with surface to be welded, is then affixed on sample surface, two exemplars are closed up
After ensure to move between the two, heating in vacuum brazing furnace is put into, when temperature reaches 250 DEG C, using the liter of 5 DEG C/min
Warm rate rises to 600 DEG C, and the brazing temperature for rising to brazing filler metal melts after heat preservation 10min again is brazed.
Compared with the prior art, the present invention has the following advantages:
1. preparing, the method that sticky brazing filler material uses is simple, time-consuming is short, at low cost, without special instrument, and milling train also can be used
Flour stranding machine replaces, and only needs time half a day from mixing to molding.
2. in the organic binder that sticky brazing filler material uses, acetone only plays a part of to be pre-dissolved and finally by whole volatilization, and second
Acid butyl ester is low with dibutyl phthalate toxicity, will not cause toxic reaction.In addition, compared to methylene chloride equal solvent, second
Acid butyl ester volatilization is slower, and the process of processing can reserve more time moldings.
3. the finished product sticky brazing filler material that the method is made has higher tack, the patch of sticky brazing filler material butt-welding fitting is facilitated
It is attached, and by test, the residual ash of ABS resin is very low, will not have an impact to weld interface, and product can save for a long time,
It will not be hardened and become fragile because dry.
