The method of preparing a synthetic porous packing boards calcium silicate modified polyethylene powder filling

The present invention relates to a process for synthesizing a porous calcium silicate powder filling modified polyethylene packing boards, belonging to the packaging sheet metal processing art. The method of preparing porous calcium silicate powder is selected mainly synthetic material, dried, and antioxidant properties to improve the decrease of nuclear capability, the surface-modified silane coupling agent, the surface self-assembly, after passing it through the lubrication modified modified powder prepared as porous synthetic calcium silicate, calcium silicate and synthetic porous polyethylene powder and modified through earnest two stage extruder and sheet line forming extruder to prepare a modified synthetic porous calcium silicate powder polyethylene packaging sheet is filled. Synthetic porous calcium silicate modified powder prepared by the present invention is filled polyethylene packaging sheet has a low density, high strength, thermal insulation, sound insulation, and high adsorption characteristics. The preparation method is simple and low equipment requirements, easy operation control is easy to realize industrial production without special equipment.
