Definitions
- the present invention relates to a paste-like composition for brazing and a brazing method using the same, and in particular, a paste-like composition containing brazing material powder for joining metal, ceramic or graphite. It relates to a brazing method using it.
- Brazing methods fall into the category of welding methods, and are a type of joining method for metals, ceramics, etc.
- the brazing method is a brazing method using a brazing material having a melting point lower than that of a base material as an object to be brazed and having a melting point of 450 ° C. or higher.
- brazing is performed as follows. The brazing material applied to the surface of one of the base materials melts and heats to a temperature at which the pressure and the base material do not melt, so that the melted brazing material attracts the joint surface of the other base material by capillary action. A thin film of brazing material is formed. Thereafter, the base material is joined by cooling and solidifying the brazing material.
- the paste-like brazing material is a portion where it is difficult to supply the brazing material in the form of plate, foil, linear or powder, that is, before brazing or brazing. It is often used because it is suitable for supplying to the area where the brazing material is likely to fall.
- the pasty composition is mainly composed of a brazing material powder, a binder, and an organic solvent. Also, as a binder solution, cement for brazing and the like are commercially available. When this binder solution is used, it can be mixed with a commercially available powdery brazing material to obtain a paste-like composition.
- Brazing is performed using a reducing gas atmosphere furnace, an inert gas atmosphere furnace, or a vacuum furnace as an industrial brazing furnace. Brazing using conventional paste-like compositions Depending on the type of brazing furnace, when burn-in was performed, carbon components remained in the brazed part after brazing, and so-called leftover carbon and the like were generated, resulting in the occurrence of brazing defects. For example, when brazing is performed in a reducing gas atmosphere furnace such as a hydrogen-containing gas, no brazing failure occurs with certain pasty compositions, but inert gases such as argon gas and helium gas are not generated. When brazing was performed in an atmosphere furnace or in a vacuum furnace, brazing defects such as residual coal sometimes occurred significantly.

It is necessary to be within the range of 0 or less, preferably 1% by mass or more and 6% by mass or less, more preferably 2% by mass or more and 4% by mass or less. If the content of butyl rubber is less than 0.5% by mass, the viscosity of the paste-like composition becomes low, the coatability decreases, and the adhesion with the base material as the object to be brazed deteriorates. If the content of butyl rubber exceeds 10% by mass, the effect of using butyl rubber as a binder may be saturated, resulting in an increase in cost.
- the organic solvent contained in the paste-like composition of the present invention is not particularly limited as long as butyl rubber is soluble.

- the paste-like composition may be dried at a temperature of about 30 ° C. to about 150 ° C. After applying the paste-like composition, it is preferable to completely dry it and then transfer it to the brazing step. The reason is that, if it is not dried, the organic solvent in the applied pasty composition may be rapidly vaporized, and the applied pasty composition may be scattered by the gas. However, when using a furnace equipped with a residual heat chamber as a brazing furnace, it is not necessary to completely dry the paste-like composition after application since the organic solvent is removed in the residual heat step, It is also possible to transfer to the brazing process in the touch-dried or non-dried state.
- dry to the touch means drying to such an extent that the pasty composition does not adhere to the finger even when pressed by the finger.
