细乳液聚合炭黑/乳胶粒纳米复合粒子的制备及其性能

以可聚合分散剂1-烯丙氧基-3-(4-壬基苯酚)-2-丙醇聚氧乙烯(10)醚硫酸铵（DNS-86）为乳化剂，甲基丙烯酸甲酯（MMA）为共聚单体，通过细乳液聚合法制备了炭黑/乳胶粒纳米复合粒子。以炭黑/乳胶粒纳米复合粒子为着色剂对棉织物印花，探讨了粘合剂用量，固色温度和时间对摩擦色牢度的影响。FTIR，TEM及TGA研究结果表明细乳液聚合可以在炭黑表面包覆乳胶粒，制备炭黑/乳胶粒纳米复合粒子。炭黑/乳胶粒纳米复合粒子作为着色剂较佳印花工艺为粘合剂用量15wt%，固色温度180oC，固色时间150s。相同条件下，炭黑/乳胶粒纳米复合粒子印花织物的K/S值、摩擦牢度明显优于超细炭黑。

Preparation and printing behavior of carbon black/latex nanocomposite particles by miniemulsion polymerization

Nanocomposite particles of polymethyl methacrylate and carbon black were prepared via miniemulsion polymerization with polymer dispersant 1 - allyloxy-3 - (4 - nonylphenol) -2 - propanol, polyoxyethylene (10) ether sulfate (DNS-86). The influence of binder concentration，fixing temperature and time on rubbing fastness of cotton fabric printed by CB/Latex nanocomposite was investigated. FT-IR, TEM and TGA results confirmed that CB/Latex nanocomposite was prepared successfully. The optimal printing conditions were that the concentration of binder was 15wt%, reacted 150s under the temperature of 180℃. The K/S values and rubbing fastness of printed fabric were better than using ultra-fine carbon black under the same condition.
