| 摘 要： | 采用正交试验法,探讨了不同物质的量比、反应时间以及催化剂用量对酚醛树脂性能的影响,并借助红外光谱(FTIR)对生成产物的结构进行分析,热重分析法(TCA)对其热稳定性进行表征.通过对改性后树脂的固含量和残炭率的测定分析,得到了合成树脂的优化条件:n甲醛:n苯酚=1.3:1,反应时间100min,NaoH用量为苯酚质量的1.1%.以煤焦油为改性剂时其改性,并对其固舍量、残炭率、水分及游离酚进行测定,结果表明,加入煤焦油后树脂的品质得到了提高.

| Abstract: | In this paper,effects of initial molar ratio of phenol and formaldehyde,reaction time and amount of catalyst on the performance of modified phenolic resin were investigated by orthogonal method.Structure of the product was analyzed using FT-IR and the thermal property was observed using TG.By analyzing solid content and carbon residue content of the phenolic resins,the optimum condition was found n_F:n_P =1.3:l,reaction time is 100 min and the amount of NaOH is 1.1%by weight of phenol.by measuring solid con... |
