| titleOfInvention | Ionic polyurethane hot melt adhesive foam product and preparation method thereof |
| abstract | The invention belongs to the field of polymer high-molecular foaming materials, and particularly relates to an ionic polyurethane hot melt adhesive foam product and a preparation method thereof. The ionic polyurethane hot melt adhesive foam product comprises moisture curing polyurethane hot melt adhesive, ionic polyurethane hot melt adhesive and water. The preparation method comprises the following steps of carrying out graft reaction on an anionic surfactant containing active hydrogen and a polyurethane hot melt adhesive to prepare an ionic polymer containing NCO active groups, adding water at 35-95 ℃, and carrying out foaming reaction to prepare an ionic polyurethane foam product. Compared with the traditional polyurethane foam product, the ionic polyurethane hot melt adhesive foam product has the advantages that due to the grafting introduction of the anionic surfactant, after water is added, the hydrophilicity of a polymer system is increased, the ionic polyurethane hot melt adhesive foam product has a certain self-emulsifying effect, the foam stability is increased, the foam merging probability is reduced, foam holes are more compact and uniform, and the ionic polyurethane hot melt adhesive foam product has the characteristics of low compression deformation, high resilience, excellent mechanical strength and the like. |
