Abstract

The invention belongs to the technical field of ceramic ink dispersants, and discloses an acrylic ester block copolymer, a synthesis method thereof and its application as a ceramic ink-jet ink dispersant. The acrylate block polymer is prepared by polymerizing methyl methacrylate and N-(3-dimethylaminopropyl)methacrylamide. Its synthetic method comprises the following steps: under anaerobic conditions, monomer N-(3-dimethylaminopropyl) methacrylamide (or methyl methacrylate) generates RAFT reagent under the action of initiator and RAFT reagent The macromolecule reacts with the monomer methyl methacrylate (or N-(3-dimethylaminopropyl) methacrylamide) to generate the acrylate block polymer under the induction of the initiator. The acrylate block polymer has a good effect of covering and encapsulating the surface of inorganic particles, and has a stable dispersion system, and is mainly used in the dispersion of ceramic pigment particles for ceramic inkjet.

Description

technical field

[0001] The invention belongs to the technical field of ceramic ink dispersants, and in particular relates to an acrylic ester block copolymer, a synthesis method thereof and its application as a ceramic ink-jet ink dispersant. Background technique

[0002] Ceramic inkjet printing technology has brought epoch-making changes to China's ceramic industry since Spain, Italy, the United States and other ceramic powers were introduced into China, and it has gradually become a popular trend in the domestic ceramic industry. One of the keys to the application of ceramic inkjet technology lies in the development of ceramic inks. The development of ceramic inks with high brightness, wide color range, smooth printing, good stability, safety and environmental protection is an inevitable trend of future ceramic inkjet printing.

[0003] Ceramic ink is generally composed of ceramic pigments (colorants), solvents, dispersants, binders and other auxiliary agents. The dispers...
