一种低含氢硅油、有机硅表面活性剂及其制备方法和应用
摘要：
本发明一种低含氢硅油，通式为MDxD’yM，M表示(CH3)3SiO1/2，D表示(CH3)2SiO；D’表示(CH3)2(H)SiO；(x+y)为25~120；还提供了一种有机硅表面活性剂，采用烯丙基聚醚和上述的低含氢硅油制备而成，所述的烯丙基聚醚的通式为CH2=CH‑CH2‑(C2H4O)a(C3H6O)bR'，R'表示为1~4个碳原子的烷基、丁基、或‑OH及–C(O)CH3。本发明还提供了上述的一种有机硅表面活性剂在制备聚氨酯软质块状泡沫体中的应用。本发明的低挥发的有机硅表面活性剂可明显降低泡沫体的气味和挥发物含量。
摘要（英）：

The invention discloses low-hydro silicone oil. The general formula of the low-hydro silicone oil is MDxD'yM, wherein M represents (CH3)3SiO1/2, D represents (CH3)2SiO, D' represents (CH3)2(H)SiO, and (x+y) is 25-120. The invention further provides an organosilicon surfactant which is prepared from allyl polyether and the low-hydro silicone oil. The general formula of the allyl polyether is CH=CH-CH-(C2H4O)a(C3H6O)bR', and R' represents alkyl or butyl or -OH or -C(O)CH3 of 1-4 carbon atoms. The invention further provides application of the organosilicon surfactant for preparation of a polyurethane soft blocky foam body. The low-volatile organosilicon surfactant can remarkably reduce smell of the foam body and lower the voltatile content.
