Problems solved by technology

[0003] However, in order to produce the water-based conductive agent for alkaline manganese batteries, there are three major problems to be solved. First, in the technical scheme of the single-component water-based conductive agent for alkaline manganese batteries, it is necessary to establish Water-based" qualitative change chemical reaction, that is, there is a qualitative change chemical reaction that turns the water-based conductive agent product into a water-resistant spray film; second, control the qualitative change chemical reaction time at the moment when the spray liquid is dried to form a film; third, Reaction temperature needs to be reduced; yet, so far, there is no technical report on the successful production of water-based conductive agents that can solve the above-mentioned problems in the alkaline-manganese battery industry; The conductive agent has the same quality and can completely replace the water-based conductive agent used in the alkaline manganese battery used in the oil-based conductive agent, which has become an urgent problem to be solved in the industry

Description

technical field [0001] The invention relates to a water-based conductive agent and a production method thereof, in particular to a water-based conductive agent for alkaline manganese batteries and a production method thereof, belonging to the field of fine chemical materials. Background technique [0002] At present, the conductive agent for alkaline manganese batteries in China is an oily conductive agent (Patent No. ZL03149783.7). The oil-based conductive agent is solvent-based, containing a large amount of volatile organic solvents, which seriously pollutes the environment and poses a threat to human health; at present, it has become a product that the country requires production enterprises to gradually reduce production and transformation, and use enterprises to gradually reduce and stop using it; Therefore, there is an urgent need to develop a low-carbon, environmentally friendly and harmless water-based conductive agent product. [0003] However, in order to produce ...
