摘　　要：以苯酚和甲醛为原料,采用草酸作为催化剂,通过有机硅改性合成的热塑性酚醛树脂。讨论了催化剂草酸的含量、反应时间和有机硅的含量对改性酚醛树脂性能的影响。结果表明:当草酸含量为2.0 wt%,反应时间为2.5 h,有机硅含量为3.0 wt%时,合成改性酚醛树脂的固化时间、流动距离和挥发度等综合性能较好,合成的酚醛树脂可用作摩擦材料粘合剂。With phenol and formaldehyde as raw materials, using oxalic acid as catalyst, the modified thermoplastic phenolic resin is prepared with adding organic silicone. It was investigated oxalic acid content, reaction time and organic silicon content in the paper. The results show that the properties of phenolic resin were better when oxalic acid content, reaction time and organic silicon content were 2.0 wt%, 2.5 h and 3.0 wt%, respectively. The synthetical thermoplastic phenolic resin can be used for adhesive of the friction materials.
