Abstract
The present invention relates to silver-based soldering paste, particularly to silver soldering paste and a soldering method for silver ornaments. The silver-based soldering paste provided by the present invention is formed by mixing silver-based solder powder, soldering flux, adhesive and organic solvent according to certain proportion. The soldering paste has two functions of pre-positioning bonding and soldering. When used for soldering silver ornaments, the silver-based soldering paste shortens production period and saves solder. Soldered products have high quality. The present invention is a fitting method for soldering artworks and ornaments made of silver.
Description
The present invention relates to the silver-base solder soldering paste, especially for the soldering paste of Silver Jewelry goods of furniture for display rather than for use and the method for welding of Silver Jewelry.
At present, the solder that silver-colored goods of furniture for display rather than for uses such as complete silver colored oolong wind and other soldering with Silver Jewelry of labyrinth are used is powder such as AgCuZn system, AgCu system, AgCuAs system, and the method for soldering generally is to adopt the traditional-handwork gas brazing, its soldering processes are: at first the honeysuckle flower silk is stuck with paste with bletilla striata powder and be bonded at silver-colored tire design position, be combined into various patterns, drying is after about 24 hours under the room temperature, the powder scolder of artificial filings added be sprinkling upon the welding position after the borax powder mixes, heating again, the honeysuckle flower wire bond on carcass, is cleaned at last.This method complex procedures, the cycle is long, and production efficiency is low.And the postwelding quality problems are more.For example: because scolder is to be sprinkling upon on the workpiece, also sprinkled solder powder in those places that do not need to weld, under welding temperature, scolder on these positions dissolves and forms many protruding pits, influenced the outward appearance fineness and the quality of ornaments, and caused the preceding preliminary treatment pickling degreasing of craft of gilding subsequently unclean, so that plating back irregular colour is even, even cause waste product or cause gold-plated layer color after putting furnishings a period of time, lose the gloss of gold.
U.S. Pat 3033713 discloses a kind of solder flux that is used for silver brazing.This solder flux is to apply one deck welding agent skin on the scolder exterior skin, and it does not have paste functionality in advance.
The objective of the invention is to overcome the deficiency of existing scolder and method for welding, propose a kind of have the paste scolder that is suitable for meticulous soldering of pre-determined bit and two kinds of functions of soldering and the new technology of carrying out the Silver Jewelry soldering with this paste scolder.
Technical scheme of the present invention is: add certain organic solvent so that it possesses and has high viscosity to be beneficial to bonding and make things convenient for soldering in the money base scolder.
Feature of the present invention is to contain the money base solder powder, adding certain amount of organic solvent in the scolder of brazing flux and binding agent, making it to become paste.The organic solvent and the ratio in soldering paste (in wt%) thereof that add are respectively: ester acid butyl ester 3.0-7.0, isoamyl acetate 8.0-9.0.
The organic solvent that adds is to do as carrying, each component of soldering paste is evenly disperseed, form paste, organic carrier as feature of the present invention, before soldering, make soldering paste have good spreadability and coating, the binding agent in the cream is concentrated, give cementation thereby reach good between the pricker spare by the volatilization between dry period.During soldering, above-mentioned organic solvent remaining under the brazing temperature effect volatilizees fully or burns totally, can be in soldered fitting surface or weld seam the residual residue that influences the brazing filler metal performance.
Method for welding of the present invention is: with silver-base solder soldering paste of the present invention, be coated with or stick on the honeysuckle flower silk, the honeysuckle flower silk that will speckle with soldering paste then is attached to the design position of silver-colored carcass, under the room temperature after dry 2-5 hour, the filigree that has fixed and carcass flame or in stove heating soldering, after the soldering, available hot water or rare citric acid water clean the face of weld.
Compared with prior art, the characteristics of paste scolder of the present invention are: pricker spare gives positioning function before having soldering.Because soldering paste has viscosity higher, can well be coated on silver-colored carcass surface before soldering, therefore,, just filigree can be bonded on the carcass design position as long as be stained with filigree.
Method of the present invention has following advantage:
(1) simplifies traditional processing technology, shortened the production cycle, be easy to realize the automation of producing in batches.
(2), thereby saved the consumption of silver solder because the non brazing part no longer sprinkles solder powder.
(3) presentation quality of product and the stability of surface quality have been improved.
Embodiment one:
Solder paste composition (in wt%):
（1）Ag Cu28 75;
(2) polymethyl methacrylate 5.0;
（3）Na
2B
4O
79.0;
(4) organic solvent: butyl acetate 3.0, ethyl ester isopentyl ester 8.0.
Each component is mixed according to the above ratio and stir, can use.Under 800 ℃ of temperature, carry out soldering, after the soldering, with hot water with soldering after the residue wash clean.
Embodiment two
Soldering paste is formed (in wt%):
(1) the Ag56Cu22Zn17Sn5 solder powder 70;
(2) polymethyl methacrylate 5;
（3）B
2O
33、KBF4 2、KF 4;
(4) butyl acetate 7, isoamyl acetate 9.
With each component mixing according to the above ratio, soldering under 750 ℃ of temperature is cleaned the face of weld with 15% citric acid water after the soldering.
Embodiment three: accompanying drawing is seen in the soldering of silver bracelet
Description of drawings
1, silver bracelet bracelet body
2, honeysuckle flower silk
3, vegetarian noodles.
Claims (2)
1, a kind of silver-base solder soldering paste that contains money base solder powder, brazing flux, binding agent, it is characterized in that this silver-base solder soldering paste contains organic solvent butyl acetate and isoamyl acetate, its content (in wt%) in the money base soldering paste is butyl acetate 3.0-7.0, isoamyl acetate 8.0-9.0.
2, a kind of method for welding that utilizes the Silver Jewelry of the described money base soldering paste of claim 1 is characterized in that with the money base soldering paste honeysuckle flower silk being sticked on silver-colored carcass design position, under the room temperature dry 2-5 hour, utilizes flame or heating soldering in stove.
