A rapid method for the preparation of environmental dense membrane

A rapid method for preparing green compact separation membrane, belonging to the field of membrane separation. Said method comprising: a porous base film is fixed to the rotary table carrier film, film surface temperature and the porous substrate film is 60-200 deg.] C; respectively liquid oligomer and the curing agent solution was sprayed in an atomized manner porous the surface of the base film, the liquid oligomer in situ crosslinking reaction in the porous surface of the base film, to obtain a dense, defect-free separation. The method of the present invention provides a simple, greatly reducing the deposition time and improve the efficiency of the film; and green, green, having a universal, easy-to-scale preparation and application.
