共聚物分散剂对氧化铁红颜料的分散作用
Dispersion of Iron Oxide Red Pigmentby Copolymer Dispersant
摘要
Abstract
A copolymer dispersant was synthesized with maleic anhydride (MA), acrylic acid (AA) and butyl acrylate (BA) as monomers. The dispersity of iron oxide red pigment particles in the suspension is improved at different amounts of the as-synthesized dispersant. The effects of monomer molar ratio, dosage of initiator, dosage of chain transfer agent, reaction time and temperature on the dispersion of the particles were investigated, and the synthesis conditions were optimized. The results show that the copolymer dispersant possesses the superior dispersive capability on iron oxide red pigment under the optimum reaction conditions (i.e., MA:AA:BA molar ratio of 2:1:0.25, reaction temperature of 85oC, initiator dosage of 8％ and chain-transfer agent dosage of 20％). The abrasion resistance of colored sand can be enhanced when the copolymer dispersant is used in the preparation of man-made colored sand.关键词
