Abstract

The invention discloses a nano-carbon aqueous anionic dispersant, and the nano-carbon water-based anionic dispersing agent is composed of the following raw materials in parts by weight: 50-60 parts ofa first dispersion, 50-60 parts of a second dispersion, 30-40 parts of an anionic surfactant and 100-130 parts of deionized water. The first dispersion and the second dispersion belong to negativelycharged anionic dispersants, are easy to dissolve in water and have a good dispersion effect, the first dispersion and the second dispersion are compounded with the anionic surfactant, so that the water-based anionic dispersing agent with strong affinity with nano-carbon can be obtained, the water-based anionic dispersing agent can be combined with the nano-carbon to generate a negatively chargedgroup, the nano-carbon is mutually exclusive and stably dispersed in a water solution, the nano-carbon is dispersed in the water solution and is not easy to precipitate, and the nano-carbon and the positively-charged pore wall have better binding force.

Description

technical field [0001] The invention belongs to the field of direct metallization of flexible circuit boards, and in particular relates to a nano-carbohydrate anion dispersant. Background technique [0002] At present, most flexible circuit boards replace the chemical copper process by depositing nano-carbon black. The process of depositing nano-carbon black is characterized by first using an electrostatic regulator to make the surface of the substrate in the hole positively charged, and then soaking with The aqueous solution of dispersed nano-carbon black (referred to as black hole liquid) makes the carbon black deposited in the pores, so as to realize electrical conductivity. However, the black hole liquid currently on the market will be affected by gravity after being placed for a period of time, and the carbon black will precipitate to deactivate the black hole liquid. Contents of the invention [0003] The purpose of the present invention is to overcome the above pro...
