首发时间:2010-11-26
摘要:以α, ω-二羟基聚二甲基硅氧烷(WS-62M)、N-β-氨乙基-γ-氨丙基甲基二甲氧基硅烷(DL-602)、单端环氧聚醚(X-09)为主要原料,合成了一系列聚醚改性氨基聚硅氧烷,探讨了最佳改性条件,并考察了DL-602用量、n(X-O9):n(DL-602)对聚醚改性氨基硅油乳液性能及其应用性能的影响,结果表明:以异丙醇作溶剂,偶联剂用量为10%,n(X-O9):n(DL-602)=3:1,80℃下反应4h为最佳反应条件;所制聚醚改性氨基硅油乳液稳定性好,整理织物白度和亲水性较氨基硅油提高,摩擦系数相差不大,耐洗。

Synthesis and application of polyether modified amino-silicone
Abstract:A series of polyether modified amino-silicone were synthesized from α, ω-dihydroxypolydimethylsiloxane(WS-62M),N-β-aminoethyl-γ-aminopropyl methyl dimethoxy siloxane(DL-602) and single-ended epoxy polyether. Suitable modified conditions were obtained, and the influence of the mass percentage of DL-602 and the molar ratio of DL-602 to X-09 on the properties and application performance of polyether modified Amino-silicone solution was explored. Experiment results showed that the optimum experimental conditions were that isopropanol as solvent, DL-602 dosage was 10%, n(X-O9):n(DL-602)=3:1 and reacted at 80℃ for 4h. The stability of the prepared polyether modified amino-silicone emulsion was good, compare with amino-silicone, the whiteness and hydrophilic of the fabric treated with this product were improved, little difference in the coefficient of friction, washable.
Keywords: polyether modified Amino-silicone synthesis emulsion properties application performance
