摘要： Provided is a method for preparing a crosslinked polyvinyl chloride structure foamed material by using a physical foaming agent, comprising: melting and mixing a polyvinyl chloride resin, a modified resin, an isocyanate, an anhydride, a nucleating agent and a heat stabilizer to obtain a blank; immersing the blank into a foaming gas for foaming to obtain a foamed body; and subjecting the foamed body to crosslinking curing to obtain a crosslinked polyvinyl chloride structure foamed material. According to the present invention, the crosslinked polyvinyl chloride structure foamed material is prepared by means of a brand-new process route, and the composition and proportion of the PVC resin and other raw materials can be adjusted in a wide range; and carbon dioxide or nitrogen is used for foaming. Further provided is a crosslinked polyvinyl chloride structure foamed material.

摘要： A three-dimensional object is formed by 3D printing, especially by a binder jetting method, in which particulate material in a powder bed is bonded by a printed adhesive. The particulate materials may be inorganic materials, for example sand or a metal powder, or particulate polymeric materials, for example polymethacrylates or polyamides. For this purpose, polymethacrylates may take the form, for example, of suspension polymers, called bead polymers. Powder bed compositions comprising core-(shell)-shell particles can be used for 3D printing, wherein the core-(shell)-shell particles can swell in contact with the binder during the printing operation.
