Abstract: In this paper，using Octamethylcyclotetrasiloxane(D4) and Glycidoxypropyltrimethoxysilane (KH-560) as raw material，KOH as catalyst，epoxy modified silicone oil was synthesized by emulsion polymerization，then polyether amine D-400 was introduced to make amino polyether modified silicone oil by the reaction of epoxy groups and amino，and the product structure was characterized by IR spectrum. The orthogonal experiments were conducted to investigate how different reaction conditions affect the ammonia value，viscosity and solid content of the product. The results showed that the optimum process parameters are as follows：the molar ratio of D4 and KH-560 is 4∶1，the quantity of catalyst is equal to 0.2% of feedstocks，emulsifier dosage is 30%，the complex formulation ratio of AEO-3 to AEO-9 is 1∶1，the reaction temperature is 90 ℃，and the reaction time is 4h. The results of the characterization measurement indicated that the stability of products is good，amino value is 0.89 mmol/g，viscosity is 73 mPa?s，and solid content is 30%.

摘要： 以八甲基环四硅氧烷（D4）、?-(2,3环氧丙氧)丙基三甲氧基硅烷（KH-560）为原料，以氢氧化钾为催化剂，采用乳液聚合法合成环氧基改性硅油，再通过环氧基与氨基的反应将聚醚胺D-400引入，制成氨基聚醚共改性硅油，并通过红外光谱对产物结构进行了表征。通过正交实验，探讨了不同反应条件对改性硅油氨值、黏度和固含量等因素的影响。结果表明：八甲基环四硅氧烷与硅烷偶联剂KH-560的物质的量比为4∶1，催化剂用量为反应物质量的0.2%，乳化剂用量为30%，AEO-3与AEO-9的复配比为1∶1，反应温度为90 ℃，反应时间为4 h是较理想的工艺参数，通过表征测定其产物稳定性较好，氨值为0.89 mmol/g，黏度为73 mPa?s，固含量为30%。
