The invention discloses an elastic polyether type acrylate emulsion which is mainly prepared from the following raw materials: deionized water, a compound emulsifier, polyether polyol, sodium bicarbonate, a core pre-emulsion, a shell pre-emulsion, an initiator and a redox agent. The compound emulsifier adopts polyether polyol with different molecular weights, esterification reaction is performed under the action of a catalyst and a polymerization inhibitor to obtain a macromonomer polymer emulsifier, and the macromonomer polymer emulsifier and the auxiliary compound emulsifier are mixed to obtain the compound emulsifier; adding deionized water and a compound emulsifier into a container, uniformly stirring, adding an acrylate monomer, and stirring to obtain a core pre-emulsion; the preparation method comprises the following steps: adding deionized water into a container, stirring, adding a compound emulsifier and vinyl siloxane, and stirring to obtain a shell pre-emulsion; according to the elastic polyether ac
