Abstract
Belonging to the technical field of synthetic paper preparation, the invention relates to a synthetic paper preparation method based on emulsion polymerization. The method includes the steps of: adding water and an emulsifier into a reactor, stirring the mixture evenly, then adding divinyl benzene, vinylidene chloride and acrylonitrile, stirring the mixture evenly, and then adding an initiator, performing heating to carry out polymerization reaction, then adding ferric trioxide and powder, stirring the mixture evenly, and conducting pumping filtration to obtain a polymer, then washing a filter cake with ethanol, and drying the filter cake to obtain a prepolymer; mixing the prepolymer, polyethylene, polypropylene, plant fiber, starch, a surfactant, dicumyl peroxide, calcium stearate, zinc stearate and an antioxidant evenly to obtain a mixture; and sending the mixture into a twin-screw extruder to undergo extrusion granulation, then performing blow molding on the obtained pellets, and conducting cutting. The powder granules are coated by means of emulsion polymerization, and the mechanical strength of the synthetic paper can be improved.
