【摘要】 将纳米三氧化二镧（La₂O₃）粒子加入氰酸酯树脂（CE）基体中,以二月桂酸二丁基锡（BDTL）为引发剂,制得CE/La₂O₃系列复合材料。通过力学性能及耐腐蚀性测试研究了纳米La₂O₃用量对材料性能的影响。结果表明,当纳米La₂O₃添加质量分数为0.3%时,材料弯曲强度达到155.45 MPa,较纯CE提高了83.8%,耐酸腐蚀性最佳,腐蚀率仅为0.09%。纳米La₂O₃添加质量分数为0.4%时,材料冲击强度达13.05 kJ/m2,较纯浇铸体板材提高了48%,耐碱腐蚀性最佳,腐蚀率仅为0.08%。将纳米La₂O₃粒子引入CE基体后,优化了CE树脂的性能。更多还原

【Abstract】 The CE/La₂O₃ series composites were prepared by adding nano lanthanum trioxide（La₂O₃）particles with dibutyltin dilaurate（BDTL）as initiator to the cyanate ester resin（CE）matrix. The effects of nano La₂O₃ dosage on the material properties were investigated by mechanical property and corrosion resistance tests. The results showed that when the mass fraction of added nano-La₂O₃ was 0.3%,the flexural strength of the material reached 155.45 MPa,which was 83.8% higher than that of the pure CE.The acid corrosion resistance was the best,and the corrosion rate was only 0.09%. When the mass fraction of nano-La₂O₃ was 0.4%,the impact strength of the material was 13.05 k J/m2,which was 48% higher than that of the pure cast sheet. The alkali corrosion resistance was the best,and the corrosion rate was only 0.08%. After adding the nano La₂O₃ particles to the CE matrix,the performance of the CE resin was optimized.更多还原
