Abstract

The invention relates to a porous membrane material continuous radiation grafting method and support equipment therefor, belonging to the technical field of graft copolymerization. The method comprises the following steps: a macromolecule porous membrane material with absorbed allyl monomer aqueous solution or aqueous emulsion passed through an electron beam irradiation chamber for carrying out electron beam electron beam in an expansion mode. The method features simple process, can be used to overcome the defect of discontinuous pre-irradiation and copolymerization irradiation in the prior art and is conducive to industrialized application of the radiation grafting technology. Meanwhile, according to the characteristics that the porous membrane material is porous and easy to be continuously transmitted, electron beam irradiation is directional and absorption dose is large, the invention further provides the support equipment for carrying out the porous membrane material continuous radiation grafting method; the equipment comprises an electron accelerator, an irradiation chamber connected with the electron accelerator, a coating device and a guidance device for guiding the coated macromolecule porous membrane material to pass through the irradiation chamber. The equipment features high automation degree, high pertinence and excellent application prospect.
