Document Type and Number:
WIPO Patent Application WO/2024/096089
Kind Code:
A1
Abstract:
The present invention provides: a mixed powder for paste brazing materials; a paste brazing material which is produced using this powder; and a method for producing a paste brazing material. A paste brazing material according to the present invention is able to be produced by mixing 8.0 parts by mass to 22.0 parts by mass of an aqueous solution that contains an organic solvent or the like into 100 parts by mass of a mixed powder for paste brazing materials, wherein the mass ratio of a brazing filler material powder to a resin powder, which serves as a water-soluble thickening agent, is 99.88-97.90:0.12-2.10. It is preferable that the resin powder is composed of a cellulose-based material; and it is particularly preferable that the resin powder is composed of one or two materials selected from among methyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose and hydroxypropylmethyl cellulose.
