| Impact strength, KJ/m 2 | 110 | 112 | 111 | 110 |
From the test data in the table above, it can be seen that:
the proportion of the hyperbranched polyesteramide powder in the modified TPU resin has a certain influence on the impact strength of the TPU composite material of the final product, and the comparison shows that the mass ratio of the TPU resin to the hyperbranched polyesteramide powder to the curing agent to the accelerator is 100 (3-10): 5: within 10, the performance of the obtained TPU composite material is optimal.
Test III, influence of modification of TPU resin on TPU composite Material Performance
Comparative example 5: the raw material composition was identical to that of example 1 except that the TPU resin was not modified at all;
comparative example 6: the raw material composition was identical to that of example 2 except that the TPU resin was not modified at all;
comparative example 7: the raw material composition was identical to that of example 3 except that the TPU resin was not modified at all;
the procedure for the preparation of TPU composite of comparative examples 5-7 above is the same as that of example 1 except that the "modified TPU resin" in the preparation of example 1 is replaced by a "TPU resin".
Test object: TPU composites prepared in examples 1-3, comparative examples 1, 3 and comparative examples 5-7;
the testing method comprises the following steps: the test standard is consistent with the test standard of the test I;
test results:
from the test data in the table above, it can be seen that:
(1) The tensile strength of the TPU composites of comparative examples 5-7 was not only lower than that of the TPU composites of examples 1-3, but also lower than that of the TPU composites of comparative examples 1 and 3, i.e., the addition of unmodified TPU resin as a starting material produced a TPU composite that failed to improve its final impact resistance;
(2) The low temperature flexural and impact strength of the TPU composites of comparative examples 5-7 are maintained at substantially the same level as the associated performance strengths of the TPU composites of examples 1-3.
Therefore, the TPU resin is modified by the hyperbranched polyesteramide, and the impact strength of the TPU composite material of the final product is obviously improved by adding the hyperbranched polyesteramide, and the tensile strength and the bending strength of the TPU composite material can still keep the original strength level.
Test IV, determining the wear resistance of the TPU composite material

| example 2 | Comparative example 8 | Reference example 1 | Test standard | |
| Wear resistance, secondary | 2000 | 1976 | 1988 | GB/T19089-2012 |
From the test data in the table above, it can be seen that:
when wollastonite is added as one of the raw materials for preparing the TPU composite material, the wear resistance of the TPU composite material can be improved, however, after the wollastonite is modified, the wear resistance of the TPU composite material can be more obviously improved.

The procedure for preparing the TPU composite of comparative example 9 above is the same as that of example 3, except that no "modified montmorillonite" is added.

Test object: the TPU composites prepared in example 3, comparative example 9 and reference example 2;
test results:
from the test data in the table above, it can be seen that:
after montmorillonite is added into the raw material of the TPU composite material, compared with the TPU composite material without any montmorillonite, the TPU composite material has a certain flame retardant effect, but has no great effect on improving the air tightness. However, when aminobenzoic acid is used for modifying montmorillonite, not only the air tightness effect of TPU composite material is obviously improved, but also the flame retardant property of the TPU composite material is further improved.
