摘要:
以环氧度为25%的环氧化天然橡胶(ENR)为基质、聚多巴胺(PDA)改性的纳米TiO2(PTiO2)为填料,采用胶乳共混法制备了PTiO2 /ENR复合膜,并研究了填料PTiO2的添加量对PTiO2 /ENR复合膜力学性能、热稳定性和抗紫外老化性能的影响。结果表明,PDA提高了纳米TiO2在ENR基质中的分散性;随着填料PTiO2的加入,PTiO2 /ENR复合膜的热稳定性逐渐提高;当PTiO2添加量为5份(质量)时,PTiO2 /ENR复合膜的拉伸强度为8.15 MPa,与ENR相比提高了2.8倍,扯断伸长率为1 141%;PTiO2 /ENR复合膜经紫外线照射后力学性能保留率均超过97%,具有较好的抗紫外老化性能。
Abstract:
Polydopamine (PDA) modified nano-TiO2 (PTiO2)/epoxidized natural rubber (ENR) composite films were prepared by latex blending method using ENR with epoxy degree of 25% as matrix and PTiO2 as filler, and the effects of the addition amount of the filler PTiO2 on the mechanical properties, thermal stability and anti-ultraviolet aging performance of PTiO2/ENR composite films were studied. The results showed that PDA improved the dispersion of nano-TiO2 in ENR matrix. After the addition of the filler PTiO2, the thermal stability of PTiO2/ENR composite film increased gradually, and when the addition amount of PTiO2 was 5 phr (mass), the tensile strength of PTiO2/ENR composite film was 8.15 MPa, which increased by 2.8 times compared with that of ENR,and the elongation at break was 1 141%. The retention rate of mechanical properties after ultraviolet irradiation were more than 97%, which indicated that PTiO2/ENR composite film had better anti-ultraviolet aging performance.
