摘要
以硅烷偶联剂改性的纳米TiO2为核,阴离子乳化剂十二烷基硫酸钠(SDS)与非离子乳化剂壬基酚聚氧乙烯醚(OP-10)为复合乳化剂,其质量比为1:1,采用半连续种子乳液聚合法,制备了具有核壳结构的纳米TiO2/聚丁苯(PSB)复合乳液,其固含量最高可达50%以上,黏度可依据不同使用要求进行调节。
Based on nano-TiO2 modified by silane coupling agent as nuclear, anionic emulsifier sodium dodecyl sulfate （ SDS ）and non-ionic emulsifier OP-10 as emulsifier, mass ratio is 1 ： 1, a nano-TiO2/polystyrene-butadiene （ PSB ） composite emulsion with the core-shell structure was prepared by semi-continuous seeding emulsion polymerization method, and the performance of the composite emulsion was analyzed. The solid content of the emulsion is up to 50%. And viscosity can be adjusted according to different application requirements.
