摘　　要：以羟基硅油OHX-4081为例,考察用于乳化的表面活性剂的种类和用量、HLB值以及其他因素对硅油乳液静置稳定性、高温稳定性、离心稳定性等的影响。结果显示:在室温、HLB值10.8、TO5和TO7作为乳化剂、m(乳化剂)∶m(硅油)=25∶100、分散机转速1000 r/min,乳化时间90 min的条件下,得到的硅油乳液粒径较小,各项稳定性均达标;OT-75也适合作为羟基硅油OHX-4081的乳化剂;氨基硅油OFX-8468的加入,亦有利于羟基硅油乳液的稳定。Taking hydroxyl silicone oil OHX-4081 as an example,the effects of the types and dosage of surfactant,HLB value and other factors on the stability of static,high temperature stability and centrifugal stability of silicone oil emul-sion are investigated.The results show that under the conditions of room temperature,HLB value 10.8,TO5 and TO7 as emulsifier,m(emulsifier)∶m(silicone oil)=25∶100,dispersing machine speed 1000 r/min,emulsification time 90 min,the particle size of silicone oil emulsion was smaller,and all the stabilities reach the standard.OT-75 is also suitable as an emulsifying agent for hydroxyl silicone oil OHX-4081.The addition of amino silicone oil OFX-8468 is also beneficial to the stability of hydroxyl silicone oil emulsion.
