摘要：以含磷单体、三聚氰胺、苯酚和甲醛为原料,合成了一种含磷含氮酚醛树脂(NP-PF)。将NP-PF进行固化,通过红外、热重分析比表面及电镜分析考察了固化物的成炭过程和炭化物的结构。结果表明:含氮酚醛树脂炭化物表面粗糙疏松,孔洞结构丰富,比表面达到971.25 m^2/g。随着含磷组分的引入,NP-PF炭化物表面的孔洞变少,主体结构较为致密。由于磷氮的共同作用,NP-PF固化物的残炭率提高至57.5%,与PF固化物的残炭率相近。NPPF可以作为一种高强度炭的前驱体。
The phosphorus-nitrogen containing phenolic resins （NP-PF）were synthesized from phosphorus-containing monomer, melamine,phenol and formaldehyde and then were cured. The charting process of the cured product and the structure of the carbonized materials were investigated by FF-IR,TG, specific surface analysis and electron microscopy. The results showed that the surface of the carbide of nitrogen containing phenolic resins was rough and loose. The pore structure was rich. The specific surface was 971.25 m^2/g. With the introduction of phosphorus-containing components, the pores on the surface of NP-PF carbide were smaller and the main structure was more compact. Due to the collective role of phosphorus and nitrogen,the char yield of the cured NP-PF was up to 57.5% and similar to that of cured PF. The NP-PF resin could be used as high-strength carbon precursor.
