Description

technical field [0001] The invention belongs to the technical field of electrode films, and in particular relates to an inorganic conductive terminal film and a preparation method thereof. Background technique [0002] At present, the inorganic conductive terminal film of various voltage and large and small current electrical contact elements used in electric heating electrical equipment, instruments and electric heating elements mainly uses lead oxide as the main component. Lead oxide is indispensable as the intermediate of the film layer of the inorganic conductive terminal, and the film cannot be formed without lead oxide. When preparing the inorganic conductive terminal film, the content of lead oxide reaches more than 70%-80%. Therefore, a large amount of waste water, waste gas, waste materials and other pollutants will be generated during the preparation process, which will damage the ecological environment and seriously affect human health. What's more serious is tha...
