The present invention relates to a preparation method of polysiloxane emulsion, which comprises hyperbranched polysiloxane, linear polysiloxane, crosslinking agent, polyether modified polysiloxane and surfactant , catalyst and water. Through the reaction of hyperbranched polysiloxane, linear polysiloxane and cross-linking agent, a dense structure is formed, and the active group is further reacted with substrates such as cement mortar, so as to solve the problem of poor waterproof effect and inconvenience in the prior art. persistent problem. |
