氰酸酯树脂/纳米三氧化二铈粒子复合材料的制备及性能研究
|
摘要
为改善氰酸酯树脂自身缺陷,将纳米三氧化二铈(Ce_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/Ce_2O_3系列复合材料。实验结果表明,当纳米Ce_2O_3粒子引入量为0.2%时,材料弯曲强度达到162.40 MPa,较纯体CE浇铸体板材提高92.0%;当Ce_2O_3粒子引入量为0.3%时,冲击强度达13.56 k J/m2,较纯CE浇铸体板材提高63.4%。通过浇铸体板材微观形貌的变化,分析复合材料性能得以提高的原因。体系耐酸碱腐蚀实验中,当纳米Ce_2O_3粒子引入量为0.4%时,耐碱腐蚀性能最佳,腐蚀率仅为0.08%;当纳米Ce_2O_3粒子引入量为0.3%时,耐酸腐蚀性能最佳,腐蚀率仅为0.09%。故将纳米Ce_2O_3粒子引入CE高分子基体后,当纳米Ce_2O_3粒子含量为0.3%时,复合材料浇铸体板材综合性能最佳,改善氰酸酯树脂自身的缺陷,实现对CE树脂性能的优化。
In order to improve the defects of cyanate ester resin,CE/Ce_2O_3 series composite materials were prepared by adding nano cerium oxide(Ce_2O_3) particles into cyanate ester resin(CE) matrix and using dibutyltin dilaurate(BDTL) as initiator.The experimental results show that when the content of Ce_2O_3 nanoparticles is 0.2 %,the bending strength of the material reaches 162.40 MPa,which is 92.0 % higher than that of pure Ce cast sheet.The impact strength of 13.56 kJ/m~2 is 63.4 % higher than that of pure Ce cast sheet when Ce_2O_3 particle content is 0.3 %.Through the change of the micro-morphology of the cast sheet,the reason why the properties of the composite material are improved is analyzed.In the resisting acid and alkali corrosion resistance experiment of the system,when the content of Ce_2O_3 nanoparticles is 0.4 %,the alkali corrosion resistance is the best,and the corrosion rate is only 0.08 %.When the content of Ce_2O_3 nanoparticles is 0.3 %,the acid corrosion resistance is the best and the corrosion rate is only 0.09 %.Therefore,when nano Ce_2O_3 particles are introduced into the CE polymer matrix and the content of nano Ce_2O_3 particles is 0.3 %,the composite cast sheet has the best performance,which improves the defects of cyanate ester resin itself and realizes the optimization of CE resin performance.
