Abstract: |
Thermoplastic polyurethane elastomer(TPU)/polylactic acid(PLA) composites were prepared by extrusion molding,and the effect of plasticizer dibutyl phthalate(DBP),naphthenic oil and titanate coupling agent TCA-101 on the mechanical properties and thermal properties of the composites were investigated.The results showed that,DBP and naphthenic oil had good plasticizing effect on the TPU/PLA composites,and their addition was beneficial to the extrusion processing of the composites,but DBP would reduce the mechanical properties of the composites.Titanate coupling agent TCA-101 had good reinforcing effect on the composites. When the dosages of TPU,PLA and naphthenic oil were 178,20 and 2 g,respectively,the tensile strength of the composites reached 100. 54 MPa,and the elongation at break reached 429%. |
