| titleOfInvention | Thermoplastic polyurethane elastomer foam material with density gradient and preparation method thereof |
| abstract | The invention belongs to the field of high polymer foaming materials, and particularly relates to a thermoplastic polyurethane elastomer foaming material with a density gradient and a preparation method thereof, wherein the thermoplastic polyurethane elastomer foaming material is provided with an outer layer and an inner layer without an interface combination structure, and the density of the outer layer (1) is 0.8-1.3g/cm 3 The density of the inner layer (2) is 0.2-0.8g/cm 3 Wherein the thickness of the outer layer (A) accounts for 2-40% of the thickness of the section of the whole material, and the thickness of the inner layer (1) accounts for 60-98% of the thickness of the section of the whole material. The thermoplastic polyurethane elastomer foaming material with the density gradient is prepared by injection molding 90-99.9wt% of thermoplastic polyurethane elastomer, 0.1-5wt% of chemical foaming agent and 0-5wt% of adhesive; the product has the advantages of light weight, high resilience, wear resistance, excellent tensile strength, compression deformation, thermal dimensional stability, low temperature resistance and the like. |
