Preparation method of viscoelastic microporous elastomer |
| abstract |
The invention discloses a preparation method of a viscoelastic microporous elastomer, belonging to the fields of polymer synthesis and high polymer material preparation. The method comprises the following steps: preparing a polyurethane prepolymer from a polymer polyol; adding epoxy resin dehydrated in vacuum at high temperature into the polyurethane prepolymer to prepare a component B simultaneously containing isocyanate groups and epoxy groups; compounding a polyurethane curing agent according to a predetermined proportion, and then adding an epoxy resin curing agent to prepare a component A which has a curing function on both a polyurethane system and an epoxy system; a, B two component materials are mixed uniformly according to a proportion by a foaming machine and poured into a mould for molding; finally, the samples were demolded and post-cured. According to the invention, polyurethane resin and epoxy resin are hybridized to prepare the microporous elastomer with the IPN structure, a large number of polyurethane networks with excellent deformation recovery capability are formed, a large number of external impact energy can be consumed by depending on the special network structure in the polymer, and the microporous elastomer with the IPN structure has excellent deformation recovery capability. |
