【摘要】 以环氧树脂(E-44)为基体,氯磺化聚乙烯(CSM)为增韧剂,纳米TiO2为填料,制备了环氧树脂/CSM复合材料,研究了改性物对复合材料的拉伸性能、冲击性能及耐腐蚀等性能的影响。实验结果表明CSM质量为环氧树脂的6%、TiO2为5%时,环氧树脂/CSM复合材料性能最佳。复合材料冲击强度达到11.25MPa,拉伸强度为8.775MPa,复合材料的耐腐蚀性也得到了一定的改善。环氧树脂/CSM复合材料冲击断面扫描电镜图片表明,改性后由脆性断裂转变为韧性断裂。更多还原

【Abstract】 Used epoxy resin( E-44) as matrix,chlorosulfonated polyethylene( CSM) as a toughening agent, nano-TiO 2 as a filler,epoxy resin( E-44) / CSM composites were produced. The variations of tensile strength,impact strength and corrosion resistance of the composites with the modifiers respectively were studied. The experimental results show that the CSM quality TiO 2 as 5% of the E-44. 6%,the composites had the best performance. The impact strength of the composites were 11. 25MPa,the tensile strength of the composites were 8. 775MPa,the corrosion resistance of the composites has also been obtained some improvement. The scanning electron microscopy images of the the composites impact cross-section show that modified composite fracture transition from brittle fracture to ductile fracture.更多还原
