Abstract

The invention discloses a ramming paste adhesive for aluminum electrolytic cells and a preparation method thereof. The adhesive comprises the following components in parts by weight: 10-15 parts of brominated epoxy resin, 1-4 parts of antimony trioxide, 1-4 parts of carnauba wax, 2-8 parts of glycidyl methacrylate, 1-5 parts of a coupling agent, 1-3 parts of lauroyl peroxide, 2-6 parts of a stearic acid, 1-4 parts of barium stearate, and 5-10 parts of phenolic polybutadiene. The preparation method comprises the following steps: adding brominated epoxy resin, antimony trioxide, carnauba wax, glycidyl methacrylate, a stearic acid, barium stearate and phenolic polybutadiene into a reaction kettle, heating for reacting under the condition of inert gas protection, adding a coupling agent and lauroyl peroxide, uniformly stirring, heating for reacting under vacuum conditions, and cooling to room temperature, so that the ramming paste adhesive for aluminum electrolytic cells is obtained. The ramming paste adhesive for aluminum electrolytic cells provided by the invention has a good adhesive property, and is high temperature resistant, and acid and alkaline resistant.

Description

technical field [0001] The invention belongs to the technical field of chemical electrolysis, and in particular relates to a tamping paste binder for an aluminum electrolytic cell and a preparation method thereof. Background technique [0002] The main equipment for aluminum electrolytic production is the electrolytic cell. The life of the aluminum electrolytic cell is not only related to the cost of overhaul, the output and quality of aluminum, but also to the economic benefits of the entire enterprise. The cost of electrolytic aluminum can be reduced by extending the life of the electrolytic cell is the most effective way. There are many factors that affect the life of the aluminum electrolytic cell. Although the cathode itself is not consumed during the aluminum electrolysis process, under the action of corrosion and various stresses, the lining of the electrolytic cell will also be severely damaged over time, forcing the electrolytic cell to Stop production.
