Description

technical field [0001] The invention relates to the technical field of manufacturing special coatings, in particular to a water-based conductive coating for the inner wall of a CRT vertebra. Background technique [0002] Traditional conductive coatings are all oil-based. During the use of these products, organic solvents volatilize, which not only pollutes the environment, but also poses a great hazard to the health of construction workers. [0003] With the rapid development of the microelectronics industry, the demand for conductive coatings is also increasing. At present, the products are changing from oil-soluble to water-based. Carbon-based water-based conductive coatings are based on the advantages of high quality, low price and long life. Important position. [0004] The technology of water-based conductive coating on the inner wall of CRT cones is available; the adjustability of the conductive performance is not good, the attention to the air permeability and therma...
