GRAPHENE-BASED POLYURETHANE POROUS NANOMETER MATERIAL AND PREPARATION METHOD THEREFOR

摘要

A graphene-based polyurethane porous nanometer material and a preparation method therefor. The graphene-based polyurethane porous nanometer material is formed by mixing component A and component B according to a mass ratio of (1-2): 1. The component A comprises the following components: polyether polyol, polyester polyol, a chain extender, graphene, an anti-structuring agent, a weak reinforcing agent, a foaming agent, and a diluent; the component B comprises the following components: a tackifying resin, a tackifier, isocyanate, graphene, an anti-structuring agent, a weak reinforcing agent, a foam stabilizer, and a functional additive. The graphene-based polyurethane porous nanometer material has the advantages of porosity and small relative density.
