Definitions
- the present invention relates to raw material powder for solder paste used for joining stainless steel and the like, and to solder paste produced using the raw material powder.
- brazing filler metals containing nickel, iron, and cobalt as the main components are used, and the parts are joined by furnace brazing.
- Methods for applying the brazing filler metal include laying amorphous foil, dispenser application using a brazing paste, screen printing, and sprinkle printing, and in particular, application methods using a brazing paste are used to reduce the amount of brazing filler metal applied.
- solder paste is obtained by kneading solder powder with a binder, and requires three steps: making the solder powder, making the binder, and making the paste.
- solder paste shown in Patent Document 1.
- Hydrophobic (oil-based) and water-soluble binders are used for paste wax, but water-soluble binders are preferable because they have a lower environmental impact and do not require a working environment or explosion-proof facilities.
- water-soluble binders are preferable because they have a lower environmental impact and do not require a working environment or explosion-proof facilities.
- lumps called "mamako" lumps in which only the outer surface of powder particles or their aggregates is hydrated, forming a viscous gel layer that prevents water from penetrating into the interior
- strong stirring, long stirring, or a long dispersion period is required until the water-soluble binder is stabilized, which limits the production of paste wax.
- problems such as the viscosity of the binder being unstable due to the generation of "mamako" and the evaporation of water during production.
- the inventor has developed a new paste brazing material that suppresses the generation of mold deposits and eliminates the need for a binder manufacturing process, as well as a mixed powder for the paste brazing material.
- the mixed powder for paste brazing of the present invention contains brazing powder and resin powder, which is a water-soluble thickener, and is characterized in that the mass ratio of the brazing powder to the resin powder is 99.88-97.90:0.12-2.10.
- the resin powder used as the thickener is preferably cellulose-based, and is characterized in that the resin powder is one or two types selected from methyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, etc.
- the paste wax of the present invention can be obtained by mixing 8.0 to 26.6 parts by mass of water with 100 parts by mass of the paste wax mixed powder.
- the paste wax of the present invention can also be obtained by kneading 100 parts by mass of the paste wax mixed powder with 7.8 parts by mass or less of 1 to 3 types selected from acetone, methyl alcohol, ethyl alcohol, n-propyl alcohol, isopropyl alcohol, ethylene glycol, and glycerin (hereinafter referred to as organic solvents) in total (excluding cases where the total of the organic solvents is 0 parts by mass) and 2.0 to 20.0 parts by mass of water, in which case the total of the water and the organic solvent is 8.0 to 22.0 parts by mass.
- organic solvents glycerin
- the paste wax of the present invention can also be obtained by kneading 100 parts by mass of the paste wax mixed powder with water and one or two of the water-soluble resins polyvinyl alcohol, urethane resin, acrylic resin, and vinyl acetate in a total amount of 1.0 part by mass or less (excluding cases where the total is 0 parts by mass), in which case the total amount of water and water-soluble resin is 8.0 to 22.0 parts by mass.
- the paste wax of the present invention contains, per 100 parts by mass of the paste wax mixed powder, one to three of acetone, methyl alcohol, ethyl alcohol, n-propyl alcohol, isopropyl alcohol, ethylene glycol, and glycerin as organic solvents in a total amount of 7.8 parts by mass or less (excluding cases where the total of the organic solvents is 0 parts by mass), and one or two water-soluble resins selected from polyvinyl alcohol, urethane resin, acrylic resin, and vinyl acetate in a total amount of 1.0 part by mass or less (excluding cases where the total is 0 parts by mass), with the remainder being water, and the total of the water, organic solvent, and water-soluble resin being 8.0 to 22.0 parts by mass.
- the remaining water is preferably 2.0 to 20.0 parts by mass.
- the aqueous solution may be a solution with a solid content of 50% or less, such as polyvinyl alcohol with a solid content of about 10% by mass, urethane resin with a solid content of about 30% by mass, or vinyl acetate with a solid content of about 40% by mass.
- the solder paste of the present invention is a solder material used for furnace brazing of stainless steel, so the solder powder is preferably a solder material whose main component is nickel, iron, or cobalt.
- the brazing powder contained in the paste brazing powder mixture of the present invention is preferably an alloy powder produced by an atomization method, and its particle size is preferably 250 ⁇ m or less.
- the particle size of the brazing powder is preferably 150 ⁇ m or less, and more preferably 63 ⁇ m or less.
- the water-soluble thickener in the paste brazing mixed powder of the present invention has the function of suppressing settling and separation of the brazing powder, but if it is less than 0.12 parts by mass per 100 parts by mass of the paste brazing mixed powder, the thickening effect is weak and the brazing powder will settle, and if it exceeds 2.10 parts by mass, the viscosity of the paste brazing increases, impairing application workability and generating a large amount of decomposition gas from the resin during the brazing process, causing brazing defects, so the amount of water-soluble thickener added is limited to the range of 0.12 to 2.10 parts by mass.
- the water-soluble thickener is preferably a cellulose-based thickener that inhibits settling and separation of the brazing powder.
- water-soluble powdered thickeners other than cellulose-based ones can also be used.
- the amount of water added is less than 8.0 parts by mass per 100 parts by mass of the paste wax mixed powder, the viscosity of the paste wax will be high, impairing application workability. Furthermore, if the amount of water exceeds 26.6 parts by mass, the viscosity of the paste wax will be low, the brazing powder will be prone to settling, impairing application workability, so the amount of water in the paste wax is limited to the range of 8.0 to 26.6 parts by mass.
- an organic solvent not only allows the paste to blend in even if oil and fat adhere to the stainless steel base material, but also provides an antiseptic effect and allows the adjustment of the drying speed, whether fast or slow.
- a water-soluble organic solvent can be selected, and one to three types selected from acetone, methyl alcohol (methanol), ethyl alcohol (ethanol), n-propyl alcohol, isopropyl alcohol, ethylene glycol, and glycerin can be included.
- the total amount of water and organic solvent is preferably in the range of 8.0 to 22.0 parts by mass per 100 parts by mass of the paste wax mixed powder.
- the amount of water added is less than 2.0 parts by mass or the total amount of organic solvent exceeds 7.8 parts by mass, the amount of water that reacts with the water-soluble thickener is reduced, the viscosity of the paste wax is unstable, and the wax powder is more likely to precipitate, impairing the coating workability.
- the amount of water added is limited to the range of 2.0 to 20.0 parts by mass, and the total amount of organic solvent added is limited to 7.8 parts by mass or less.
- the paste brazing material of the present invention can contain one or two of water-soluble polyvinyl alcohol, urethane resin, acrylic resin, and vinyl acetate to suppress the settling and separation of the brazing material powder and to improve adhesion to the stainless steel base material.
- the amount added to the paste exceeds 1.0 part by mass, the amount of decomposition gas generated during the brazing process increases, causing brazing defects, so the amount added to the paste is limited to a range of 1.0 part by mass or less.
- the total amount of water and water-soluble resin is preferably in the range of 8.0 to 22.0 parts by mass per 100 parts by mass of the paste brazing mixed powder.
- the total amount of water, organic solvent, and water-soluble resin is preferably in the range of 8.0 to 22.0 parts by mass, as described above.

- the brazing filler metal powder in the present invention is preferably, for example, the Ni-based heat-resistant brazing filler metal described in Patent No. 3354922, which is composed of, by weight, 25-35% Cr, 4-8% P, 3-6% Si, a total of 9-11.5% P + Si, and the remainder Ni and unavoidable impurities.
- a paste wax can be obtained using the paste wax mixed powder of the present invention by adding a predetermined amount of a solution containing water, an organic solvent, etc. to the paste wax mixed powder and kneading it using a kneading machine (mixer) or the like.
- a brazing filler paste was prepared according to the above procedure so as to have the compounding ratio shown in Table 1. After mixing, the mixture was placed in a sealed container and stored at 25° C. for 12 hours, and the viscosity of the paste was confirmed using a Viscotester VT-06 (using a No. 2 rotor, rotor speed 62.5 rpm) manufactured by Rion Co., Ltd. It was also confirmed whether the brazing powder had settled in the sealed container.
- the mixing ratio, paste viscosity, and precipitation state of the brazing powder for the examples and comparative examples are shown in Table 1. Note that the brazing powder used was the Ni-29Cr-6P-4Si alloy powder described in Patent No. 3354922.

In all of the Examples and Comparative Examples of the paste prepared using the present invention, no formation of mold was observed.
- Example No. A shows the manufacturing details of Example No. 2 in Table 1, and in addition to manufacturing and adjusting the mixed powder for the paste brazing (Step I), the paste manufacturing process (Steps II and III) took one day.
- Comparative Example No. B which has the same components as Example No. 2, but does not mix the thickener into the paste wax powder
- the number of days required for the paste manufacturing process was one day, as in Example No. A, but the paste wax could not be used because the powder was granulated in step III of the paste manufacturing process.
- Comparative Examples No. C and No. D which have a general paste wax manufacturing process
- Comparative Example No. C which was stirred for a long time in step II of the binder manufacturing process, required a total of three days for the paste manufacturing process (the total of steps II and III), which was longer than the manufacturing time of the present invention.
- the paste wax manufacturing method of the present invention is more effective than current paste wax manufacturing methods in terms of the occurrence of mold deposits, manufacturing time, and viscosity stability of the paste wax.
- the solder paste mixed powder according to the present invention and the solder paste using the same have a viscosity suitable for application of the solder paste, and there is no settling of the solder powder, making it possible to obtain a solder paste with excellent application workability.
