With the materials of octamethyl cyclotetrasiloxane, silane coupler KH - 602 and tetramethylammonium hydroxide, a amino silicone had been synthetized. And then a hydrophilic silicone oil modified with polyether was prepared by reacting with polyether 818. Results showed that the optimal synthetic conditions were as follows; 120℃ of reaction temperature, 5. 5 hours of reaction time in the reaction of preparing amino silicone; 88 to 92 ℃ of reaction temperature, 4. 5 hours of reaction time, 0. 06% of catalyst, n(D4): n(602) = 1 : 0. 15 ~ 1 :0. 20, m(Polyether) :m(amino silicone) = 30% ,3500~4200 molecular weight of amino silicone, 35% of isopropanol in the reaction of preparing polyether silicone. Under those conditions, the polyether silicone, as a softener and smooth agent of leather, could make leather keep plump soft touch and excellent lasting smooth effect.%以八甲基环四硅氧烷(D4)、N-β(氨乙基)-γ氨丙基甲基二甲氧基硅烷(602)为原料,四甲基氢氧化铵为催化剂,合成氨基硅油；再用聚醚818对其进行改性,合成了聚醚改性氨基硅油.结果表明,最佳合成工艺条件为:制备氮基硅油反应温度为120℃,反应时间为5.5h,聚醚改性反应温度为88～92℃左右,反应时间为4.5h;最佳原料配比为:催化剂用量为0.06％,n(D4)∶n(602)=1∶0.15～1∶0.20,m(聚醚818)∶m(氨基硅油)=30％,所用氨基硅油分子量为3500～4200,异丙醇用量为35％.在该工艺条件下制得的聚醚硅油用作皮革柔软剂和滑爽剂,可使皮革具有柔软丰满的手感、优异持久的滑爽效果.
