| 摘 要： | 探讨了苯酚与桦木粉质量比（液比）、NaOH用量、苯酚与甲醛摩尔比等对酚醛树脂性能的影响,结果表明,影响酚醛树脂性能的主次依次为甲醛与苯酚摩尔比〉苯酚与木粉质量比（液比）〉NaOH用量,木材液化物制备酚醛树脂的最佳工艺条件：苯酚与木粉质量比为4,甲醛与苯酚摩尔比为2.4,NaOH用量为12 g。并对制得的酚醛树脂进行压板测试,结果表明,胶合板的胶合强度达到了国家标GB/T9846—2004Ⅰ类胶合板要求。

| Abstract: | The effects of the mass ratio of phenol to birch powder,quantity of NaOH,molar ratio of formaldehyde to phenol on the properties of PF resins.As indicated by the results,the impact of those factors on the performance of PF reduced as molar ratio of formaldehyde to phenol > mass ratio of phenol to birch powder > quantity of NaOH.Optimum condition for PF resin was determined through orthogonal experiment.The optimum preparation conditions were as follows: molar ratio of formaldehyde to phenol was 2.4,and mass... |
