摘　　要：以不同EO数的烯丙基聚醚制备有机硅表面活性剂,测定不同产物的HLB值、表面张力、润湿性能、乳化稳定性和去污性能。结果表明,EO数为8时,产物具有较好的表面活性、润湿性能和乳化稳定性,可选作润湿剂和乳化剂。随着EO链长增加,产物表面活性、润湿性能下降,但去污性能逐渐提高。EO数增加至22时,去污性能明显提高,可应用于洗涤剂等领域。The organic silicon surfactant is prepared by using allyl polyether with different number of EO. The HLB value, surface tension, emulsifying properties, wetting properties and washing properties of different products are determined. The results show that when the number of EO is 8, the surface tension, wetting and emulsifying properties of the products are best, which can be chosen as wetting age nt and emulsifying agent. With the number of EO increasi ng, the surface tension, wetting and emulsifying properties of the pruducts decrease, but the washing properties become better. When the number of EO reaches 22, the washing property of the product increases obviously, which can be used as a washing agent.
