Description

Solder powder composition for jewelry wire and processing method thereof

technical field

The invention relates to a powder composition, in particular to a welding powder composition for jewelry wires capable of effectively welding metal jewelry chain sections and a processing and application method thereof.

Background technique

Commonly used materials for jewelry are non-metallic wires with low strength such as copper and aluminum. The biggest reason for making jewelry with low-strength non-metallic materials is because it is easy to weld and prevents the welded surface from cracking or cracking during processing. However, the unit price of aluminum as a jewelry material is relatively high, and its specific gravity is light, which reduces the value of jewelry. As a jewelry material, the unit price of copper is higher than that of aluminum. Copper has a high specific gravity, durability, and high jewelry value. However, as a jewelry material, its unit price is high, and the price of jewelry is also high. The unit price of metal wire is several times lower than that of copper, but the reason why it cannot be used to make jewelry such as necklaces or bracelets is that the double welding surface of the chain is easily damaged when various processes such as positive and negative carvings are performed on its surface .

When welding ordinary metal wire, the reason why the metal wire cannot withstand the pressure of cutting or punching is that welding powder for low-strength metals is used when welding metal wire, and these solder powders can only be used for low-strength metals such as aluminum or copper. When welding general metal wires, if you want to use welding powder for low-strength metals such as aluminum or copper to cut or stamp the wires, due to the high strength of the metal wires, it needs to be subjected to a higher cutting pressure or stamping than aluminum or copper. The wire will receive too much welding pressure, and the welding surface is prone to skin damage. Therefore, although metal wire has great advantages in terms of economy and practicability, the above-mentioned problems cannot be solved by using general solder powder, and metal wire cannot be used to make jewelry materials so far.

In the past, the bonding agent used when welding the cross section of the copper chain was a solder powder made of a mixture of high-viscosity lubricating oil and metal powder solvent boric acid. The reason why this type of solder powder is not suitable for welding high-strength wire is because of the following three reasons:

First, reduce the solvency and synthesis power

Second, due to the high heat, the adhesion of the solder powder is gradually reduced, and it cannot be attached to the soldering surface for a long time and detached.

Third, solder powder is not easy to penetrate into the section.

In addition, due to the phenomenon of reduced adhesion caused by high heat, the welding surface will be weak and weak.

Contents of the invention

The purpose of the present invention is to provide a new welding powder composition for jewelry wire, so that manufacturers can produce high-quality jewelry made of metal wire, and solve the problem of welding wire by using appropriate solder powder. The unit price of metal wire is lower than that of copper It is several times lower and has advantages in terms of weight and durability. The gold plating process is easy and of good quality; when the above-mentioned powder welding composition welds metal chains, the welding surface will not crack or crack even though the metal chain is subjected to strong cutting or stamping pressure. .

Another object of the present invention is to provide a method for processing a solder powder composition for jewelry wire, which can weld a metal wire section with higher strength than copper wire for general jewelry materials, so that the metal can be used as a material for making bracelets or necklaces.

The purpose of the present invention and the solution to its technical problems are achieved by adopting the following technical solutions. According to the present invention, a solder powder composition for jewelry wires is prepared by mixing the following raw material components in percentage by weight: copper powder 10-30%; iron powder 10-20%; silver powder 10-20% %; square pillar powder 20-30%; boric acid 10-20%; borax 5-10%; butter 3-8%; castor oil 2-4%.

In addition, the present invention also proposes a processing method of a solder powder composition for jewelry wire, firstly, 10-30% copper powder, 10-20% iron powder, 10-20% silver powder, 20-30% Mix sclereid powder, 10-20% boric acid, 5-10% borax, 3-8% butter, and 2-4% castor oil to make solder powder for wire, and then use the mixed solder powder Apply evenly to the metal chain.

The metal chain is pre-treated with talcum powder, and then welded at a temperature of 1100-1200°C.

When the thickness of the metal wire increases or decreases by 0.5-1m/m, the filling amounts of the butter and the castor oil in the solder powder composition formula increase or decrease by 5-10%.

By means of the above-mentioned technical scheme, the solder powder composition for jewelry wire and its processing method of the present invention have advantages and beneficial effects as follows:

1) The present invention can weld the wire section with higher strength than the copper wire of general jewelry material, so that metal becomes the material for making bracelets or necklaces; the solder powder composition for jewelry wire of the present invention can weld the section of every metal chain, and can be connected to each other;

2) Using the welding powder for jewelry metal wire of the present invention, the welding is firm and strong; even though the metal chain is processed with positive and negative inscriptions and the welding surface is subjected to cutting or stamping pressure, the welding surface will not be broken or cracked.

Detailed ways

The solder powder composition for jewelry wire of the present invention is copper (CU), iron (TE), silver (AG), square pillar (SN) and boric acid (H ₃ BO ₃ ), borax (Na ₂ B ₄ O ₇ ), butter, and castor oil. The reasons for using these raw material components are as follows:

The first copper powder and iron powder are characterized by solidity and have advantages in processing; the second silver powder: has the characteristics of good ductility, because the ductility and softness at low temperatures are significantly increased and the synthesis rate is high; Triangular stone powder: high synthetic power and resistance to rust; fourth boric acid and borax: high solubility; fifth butter: high cohesion and adhesion; sixth castor oil: high adhesion and penetration.

The solder powder for metal wires of the present invention can also be prepared by mixing the powder raw material components in the following weight percentages. Among them, copper powder 10-30%, iron powder 10-20%, silver powder 10-20%, square pillar powder 20-30%, boric acid 10-20%, borax 5-10%, butter 3-8%, castor oil 2 to 4%.

Wherein, the particle size of the above-mentioned copper powder, iron powder, silver powder, and square pillar powder can pass through a 30-100 mesh sieve.

Since the welding time is determined according to the thickness of the wire, the filling amount of butter and castor oil can also be adjusted according to the thickness of the wire.

We all know that soldering time is extremely important. When welding copper wire, the welding time is also determined according to the thickness of the copper wire.

The reason why the filling amount of butter and castor oil is determined according to the thickness of the wire is because the thicker the wire, the longer the welding time, and the longer the solder powder needs to stick to the welding surface. The filling amount of butter and castor oil determines the adhesion of solder powder to the welding surface.

Butter also has superior adhesion and cohesion at high temperatures, which can melt boric acid, borax, copper powder, silver powder, and square pillar powder to achieve welding. However, although butter has superior adhesion and cohesion, it can only be superior to welding of non-metallic materials, and is limited to welding of wire, so there are still big problems in making jewelry with wire.

Castor oil can improve the adhesion of butter, and make the dissolved copper powder, silver powder, and square pillar powder penetrate into the cross section quickly, so that the welding surface will be firm and firm. Zinc and square pillars form a protective layer on metal surfaces with relatively monotonous colors such as copper or brass to prevent corrosion, especially the corrosion of the welding surface of metal chains. When the thickness of the metal wire increases or decreases by 0.5-1m/m, the filling amounts of butter and castor oil will increase or decrease by 5-10%.

At the same time, the thicker the wire, the longer the welding time.

The present invention is further described in detail through specific preferred embodiments below, but the present invention is not limited to the following embodiments.

Example 1

Welding processing of wire with a diameter of 2m/m

First mix 320g of copper powder, 250g of iron powder, 210g of silver powder, 210g of square pillar powder, 130g of boric acid, 60g of borax, 40g of butter, and 30g of castor oil. on a metal chain. In order to prevent the chains from sticking to each other, the chains are first treated with talcum powder and then welded at 1100-1200 °C.

Welding by the above method, the welding surface will be round and not uneven.

Example 2

Welding processing of wire with a diameter of 3m/m

First mix 319g of copper powder, 200g of iron powder, 209g of silver powder, 209g of square pillar powder, 129g of boric acid, 58g of borax, 43g of butter, and 33g of castor oil. on a metal chain. In order to prevent the chains from sticking to each other, the chains are first treated with talcum powder and then welded at 1100-1200 °C.

Welding by the above method, the welding surface will be round and not uneven.

The difference between the above-mentioned embodiment 2 and embodiment 1 is that the diameter of the former metal chain is 1m/m longer than that of the latter, the time required for welding increases accordingly, and the time required for welding powder to stick on the metal surface also increases. For this reason, increase the filling amount of butter and castor oil by 7-10%, and reduce the filling amount of other materials. When the thickness of the metal wire increases or decreases by 0.5-1m/m, the filling amounts of butter and castor oil will increase or decrease by 5-10%.

After the metal chain is made by the method provided in the above-mentioned embodiments 1 and 2, each chain is processed by cutting or stamping, etc., and then gold-plated on the surface to complete the jewelry.

The strength of the metal chain is 2 to 4 times higher than that of copper or aluminum. Therefore, the metal chain cannot be processed with the same cutting or stamping pressure as copper or aluminum, but the metal chain should be processed with 2 to 3 times greater processing pressure. If the metal chain is welded by the previous non-metallic welding method, the welding surface will be cracked or cracked and cannot be processed.

However, if a metal chain is welded with the solder powder composition for metal wire of the present invention, although the processing pressure is 2 to 3 times greater than that of copper or aluminum, the welding surface of the metal chain can be processed without cracking or cracking.

The unit price of the metal chain is several times lower than that of copper, and the solder powder composition for metal wire of the present invention can make the metal wire chain become an ornament material, thereby greatly reducing the unit price of ornament production. Moreover, compared with non-metallic materials, the gold plating process is easy and good in quality, and can produce high-quality ornaments.

The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form, so any simple modification made to the above embodiments according to the technical essence of the present invention does not depart from the content of the technical solution of the present invention. , equivalent changes and modifications all still belong to the scope of the technical solution of the present invention.
