摘要:

用八甲基环四硅氧烷、乙烯基环四硅氧烷、三氟乙酸丙烯酯共同对苯丙乳液进行改性,确定了适宜的改性单体加入量及有机硅/氟配比.乳液的红外光谱显示,得到了有机硅/氟改性苯丙乳液.研究了有机硅、氟的加入量对聚合体系稳定性、乳液涂膜性能、反应速度的影响.结果表明,随着改性单体含量的增加,反应速度有所降低;当控制体系中改性单体质量分数≤15%时,八甲基环四硅氧烷、乙烯基环四硅氧烷、三氟乙酸丙烯酯配比对乳液稳定性没有影响.

Abstract:

The phenylene acrylic emulsion was modified with octamethylcyclotetrasiloxane, vinyl cyclotetrasiloxane and propylene trifluoroacetate, and the appropriate amount of modified monomer and the silicone/fluorine ratio were determined. The infrared spectrum of the emulsion showed that the silicone/fluorine-modified styrene acrylic emulsion was obtained. The effects of silicone and fluorine on the stability of polymerization system, the performance of emulsion coating film and reaction speed were studied. The results showed that with the increase of the content of modified monomers, the reaction speed decreased. When the mass fraction of modified monomer in the control system ≤15%, the ratio of octamethylcyclotetrasiloxane, vinyl cyclotetrasiloxane and propylene trifluoroacetate had no effect on the stability of the emulsion.
