织物用聚醚改性氨基硅油柔软剂的合成

以α,ω-二羟基聚二甲基硅氧烷(WS-62M)、N-β-氨乙基-γ-氨丙基三甲氧基硅烷(SG-Si900)和聚氧乙烯甲基缩水甘油醚(GPOME)为原料,经酯交换和开环反应合成了可用于织物柔软整理的聚醚改性氨基硅油,用它整理后的织物具有柔软的手感、较好的白度和吸水性。氨基硅油的最佳合成条件:n(WS-62M)/n(SG-Si900)=1.33:1,ω(三乙胺)=1.53%,反应温度120℃,反应时间10 h,在0.01 MPa 条件下抽真空0.5～1h。聚醚改性氨基硅油的最佳合成条件:n(GPOME)/n(氨基硅油)=7.2:1,m(异丙醇)/m(GPOME+氨基硅油)=1:1,反应温度80℃,反应时间5 h。

SYNTHESIS OF POLYETHER-CONTAINING AMINOPOLYSILOXANE FABRIC SOFTENER

Using α,ω-dihydroxydimethylpolysiloxane(WS-62M),N-β-aminoethyl-γ-aminopropyltrime- thoxysilane(SG-Si900)and glycidyl polyoxyethylene methyl ether as starting materials,polyether-con- taining aminopolysiloxane fabric softener that can impart good soft handle,whiteness and wettability power to fabrics,was synthesized by ester interchange and ring-opening reactions.The aminopolysi- loxane with regular distribution of amino groups in the molecule was synthesized under the conditions that the molar ratio of WS-62M to SG-Si900 was 1.33:1,the mass ratio of triethylamine was 1.53%,reaction temperature was 120 ℃,reaction time was 10 h,and vacuum time under a pressure of 0.01 MPa was 0.5～1 h.The optimum reaction conditions of polyether-containing aminopolysilox- ane were obtained as follows:the molar ratio of glycidyl polyoxyethylene methyl ether to aminopolysi- loxane 7.2:1,the mass ratio of isopropanol to glycidyl polyoxyethylene methyl ether and aminopol- ysiloxane 1:1,reaction temperature 80℃,reaction time 5 h.
