| 中文摘要: |
| 通过一步法制备纳米淀粉/乙烯-乙酸乙烯酯橡胶（EVM）复合材料，研究偶联剂KH570对复合材料性能的影响。结果表明：在不添加偶联剂KH570时，复合材料的物理性能明显提高，但纳米淀粉与EVM基体的相容性较差；偶联剂KH570的加入可以改善纳米淀粉与EVM基体的相容性；随着偶联剂KH570用量的增大，复合材料的硬度、300%定伸应力和拉伸强度逐渐增大；在本试验范围内，偶联剂KH570用量为2份时，复合材料的物理性能最佳。 |
| 英文摘要: |
| The nanostarch/ethylene-co-vinyl acetate rubber（EVM） composites were prepared by one-step method，and the effects of coupling agent KH570 on the properties of the composites were investigated.The results showed that，without coupling agent KH570，the physical properties were improved，but the compatibility between nanostarch and EVM matrix was poor. The addition of coupling agent KH570 could improve the compatibility of nanostarch and EVM matrix，and as the addition level of coupling agent KH570 increased，the hardness，modulus at 300% elongation and tensile strength of the composites increased gradually. In the range of this experiment，when the addition level of coupling agent KH570 was 2 phr，the physical properties of the composites were the best. |
