According to the preparation method, hydroxyl polysiloxane, terminated hydrogen-containing polysiloxane quaternary ammonium salt and a cross-linking agent form an active substance with a cross-linked network structure under the action of a base catalyst, so that the film-forming property and the waterproof property of the emulsion are improved; a composite surfactant is introduced, namely the composite surfactant is obtained by reaction of polyether modified polysiloxane and polysiloxane quaternary ammonium salt through hydrogen-bond interaction, the stability of an emulsion system is improved, meanwhile, the surfactant can improve the dispersion and permeability of the system, siloxane groups and emulsion active substances cooperate, and the dispersion and permeability of the system are improved. The waterproof performance of the emulsion is further improved, and polysiloxane quaternary ammonium salt is introduced, so that the emulsion has a mildew-proof effect. 本发明公开了一种有机硅乳液及其制备方法，将羟基聚有机硅氧烷、端含氢聚硅氧烷季铵盐和交联剂在碱
