【摘要】 利用单体配位插层法制备酚醛树脂/蒙脱土纳米复合材料,并对不同蒙脱土含量的复合材料在软化点、粘结剪切强度和热稳定性方面与纯酚醛树脂进行比较.结果表明:当蒙脱土质量分数为2%~5%时,复合材料的软化点变化不明显;不同蒙脱土含量的酚醛树脂/蒙脱土纳米复合材料的粘结剪切强度均高于纯酚醛树脂;在温度低于300℃和温度高于400℃时复合材料在热稳定性方面均优于纯酚醛树脂.更多还原

【Abstract】 Phenolic resin/montmorillonite nanocomposites were prepared by monomer coordination and intercalative polymerization.Compared with pure phenolic resin,when content of montmorillonite was(2 %～5 %),there was not obvious change in the softening point of nanocomposites and adhesive intensity of nanocomposites was better.When the temperature was less than 300 ℃ or more than 400 ℃,nanocomposites were superior to phenolic resins in thermal stability.更多还原
