氰酸酯树脂/纳米三氧化二镧复合材料研究
|
摘要
将纳米三氧化二镧(La_2O_3)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/La_2O_3系列复合材料。通过力学性能及耐腐蚀性测试研究了纳米La_2O_3用量对材料性能的影响。结果表明,当纳米La_2O_3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La_2O_3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La_2O_3粒子引入CE基体后,优化了CE树脂的性能。
The CE/La_2O_3 series composites were prepared by adding nano lanthanum trioxide(La_2O_3)particles with dibutyltin dilaurate(BDTL)as initiator to the cyanate ester resin(CE)matrix. The effects of nano La_2O_3 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-La_2O_3 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-La_2O_3 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 La_2O_3 particles to the CE matrix,the performance of the CE resin was optimized.
