Problems solved by technology

Obviously, the traditional method of bonding with epoxy resin can be bonded, but it is very difficult to reopen after curing. Therefore, in the conventional method of bonding with epoxy resin, the opening of the amorphous core has to be bonded. , which affects the performance of amorphous core and amorphous transformer

Abstract

The invention discloses a method for flexible bonding of an amorphous alloy steel sheet and a special bonding compound. The special bonding compound comprises the following components by weight: 100 parts of liquid polysulfide rubber, 20 to 28 parts of a coumarone-indene resin, 35 to 45 parts of asbestos powder, 0.1 to 0.3 parts of dibutyl phthalate, 3 to 7 parts of filament glass fiber, 0.3 to 0.6 parts of a promoter TT, and 1 to 2 parts of zinc oxide. According to the method for the flexible bonding of the amorphous alloy steel sheet and the special bonding compound provided in the invention, the processing efficiency and the performance level of an amorphous alloy iron core can be effectively improved with substantial effects; meanwhile, an amorphous transformer product, which is more energy efficient and has low noise, can be produced.

Description

technical field [0001] The invention relates to a method for flexibly bonding amorphous alloy steel sheets and a special bonding glue, belonging to the field of design and manufacture of power transformers. Background technique [0002] The application of amorphous alloy core as a magnetic circuit in the production of amorphous alloy transformer can make the amorphous transformer obtain very excellent low loss characteristics. In the manufacture of amorphous alloy transformers, the low loss level of amorphous alloy core represents the level of energy saving and consumption reduction of amorphous transformers. Therefore, the low loss characteristics of magnetic conduction of amorphous cores are very important for obtaining high-quality amorphous transformers. [0003] The amorphous core is cut and assembled from amorphous alloy steel strips. The quality of the cutting process and assembly process determines the performance of the amorphous core. In the assembly process, the ...
