以Ba(OH)2为催化剂,合成了水溶性钼酚醛树脂MoPF,研究了原料(苯酚、甲醛、钼酸铵和Ba(OH)2)配比、反应温度和时间对合成的影响,并用红外光谱、热重分析和差热分析对所粘接岩棉的结构和耐热性进行考察。结果表明,当m甲醛∶m苯酚∶m钼酸铵=3∶1∶0.54,60℃恒温反应1 h后升温至70℃,并于70℃恒温反应2 h,MoPF所粘接岩棉的耐热性与纯酚醛树脂( PF)相比有明显提高。初始分解温度为450℃,比PF-岩棉提高190℃；885℃时失重8%,比PF-岩棉减少22%；红外光谱表明,钼元素以钼氧键的形式引入到PF结构中。

Water soluble Mo-phenolic formaldehyde( MoPF) resin was synthesized with Ba( OH) 2 as cata-lyzer. Effect of proportion of raw materials ( including phenol,formaldehyde,ammonium) ,reaction temper-ature and time were studied. Meanwhile,the structure and thermal resistance of the rock wool were investi-gated by fourier transform infrared spectroscopy,thermogravimetric and differential scanning calorimetry a-nalysis. When m(formaldehyde)/m(phenol)/m(ammonium) =3∶1∶0. 54,the reaction temperature and time is 60 ℃ for 1 h and 70 ℃ for 2 h,the heat resistance of MoPF is obviously improved compared with pure PF. The initial decomposition temperature is 450℃,which is increased by 190℃ compared with the PF-rock wool. The weightlessness is 8%,which is decreased 22% at 885 ℃. The bond exist between Mo and PF from the IR spectrum analysis.
