Problems solved by technology

For the convenience of use, these alloy powders (-100 mesh ~ 800 mesh) are usually mixed with various binders to make paste solder, and then the paste solder is applied to the waiting However, for parts with special structures such as honeycomb and irregular contact surfaces, these solder preset methods have disadvantages such as difficult operation and low efficiency.
[0003] In order to solve the above problems, it is the best solution to make these brittle brazing materials into sticky solder or further process them into preformed solder. Alkanes and other irritating solvents have a certain impact on the environment. The production cycle of the adhesive tape solder is long, and the strength is insufficient, and it is easy to break. In addition, it is difficult to prepare ultra-thin adhesive tape solder in the existing technology

Embodiment 1

[0028] To prepare a nickel-based high-temperature adhesive tape solder with a thickness of 2.0 mm, the operation steps are as follows:

[0029] (1) Take 170g of binder and 830g of nickel-based high-temperature solder powder with a mesh number of -100~800 mesh, mix and stir evenly to form a paste;

[0030] (2) Pour the paste into the extrusion barrel of the extruder, and install the needle;

[0031] (3) Adjust the roller spacing to 2.2mm;

[0032] (4) Start the preparation device, adjust the rotation speed of the rolls, the release paper tray, the receiving tray and the rolls run synchronously, pass the upper and lower layers of release paper through the gap between the rollers, and then wind them on the receiving tray;

[0033] (5) Start the extruder, extrude a strip paste on the center line of the lower release paper, the strip paste forms a strip-shaped solder under the co-extrusion of the release paper and the roll, and then collect it in the receiving In the plate;

Abstract

The invention discloses a high-temperature adhesive tape solder preparation device and method. The preparation device comprises release paper trays 1, a material extruding machine 2, a roller rolling machine 3 and a material collecting disc 4. The preparation method comprises the following steps: firstly mixing a high-temperature welding powder and an adhesive to form a paste; secondly loading the paste into the material extruding machine 2 and extruding strip-shaped paste on a release paper by the material extruding machine 2, rolling the mixed paste isolated by the release paper by the roller rolling machine 3, and finally placing the material collecting disc 4 which has collected the strip-shaped solder in a constant-temperature drying chamber provided with ventilation facilities, and carrying out drying treatment. According to the invention, the extrusion action force of the double-roller rolling mill is utilized, so that the mixed paste of the adhesive and the high-temperature welding powder flows in the two-dimensional space of the release paper, the gap and the rotating speed of the roller are controlled to obtain the high-temperature adhesive tape solder which is flat in surface, compact in the overall density and uniform in thickness. The method is simple and easy to operate and the industrial production is easy to achieve.

Description

technical field [0001] The invention relates to the technical field of brazing material processing, in particular to a device and method for preparing high-temperature adhesive tape brazing material. Background technique [0002] High-temperature solders such as nickel-based, cobalt-based, manganese-based and copper-based, etc., usually add silicon, boron, phosphorus and other elements to form binary or multi-element alloys in order to achieve the purpose of lowering the melting point. These alloys generally have greater brittleness and do not It can be processed into filaments, strips, flakes and other shapes, and it is only used in powder state. For the convenience of use, these alloy powders (-100 mesh ~ 800 mesh) are usually mixed with various binders to make paste solder, and then the paste solder is applied to the waiting However, for parts with special structures such as honeycomb and irregular contact surfaces, these solder preset methods have disadvantages such as ...
