Preparation of a Novel Dispersant for Carbon Black Dispersing and Fixing
Abstract:The branched poly (styrene-alt-maleic anhydride) (BPSMA) was synthesized by chain transfer polymerization of styrene (St) and maleic anhydride (MA) using (4-vinylphenyl)methanethiol (VPMT) as a chain transfer agent and benzoyl peroxide (BPO) as an initiator. Fourier transforms infrared (FTIR) spectroscopy, 1H nuclear magnetic resonance (NMR) spectroscopy and gel permeation chromatography (GPC) BPSMA confirmed that the copolymer with the branched structure. BPSMA exhibited high dispersing efficiency for CB particles, and prepared CB dispersion showed excellent stability to centrifugal forces and treatment temperature. In addition, BPSMA can also greatly improve the prubbing and washing fastness of the cotton fabrics when cotton fabrics was printed using this dispersion.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
