The invention relates to a production method of waterborne polyurethane polystyrene foam surface gloves, which is characterized in that the step of dipping a coagulator on the surface of a glove lining is omitted before the glove lining is dipped in waterborne polyurethane emulsion, so that the glove production steps are simplified, the use of raw materials is reduced, and the energy consumption is also reduced; the sewage generated in the production process and the pollution of the sewage to the environment are reduced. In addition, through the arrangement of the large-particle-size polyurethane aqueous dispersion, the production method of the gloves reduces permeation of the impregnation liquid to the inner side of the glove lining, further improves the wearing comfort of the manufactured gloves, and through the arrangement of the surfactant and the foaming auxiliary agent, the foaming effect of the waterborne polyurethane emulsion is improved, so that the service life of the gloves is prolonged, and the se
