Wood has always maintained an important position in construction engineering and decoration due to its unique excellent characteristics, but its flammability has limited various application. In this study, phytic acid (PA) derived from plant seeds and uracil (U) derived from ribonucleic acid (RNA) were prepared as water solution, and natural wood just through physical infiltration in the water solution to obtain wood/PA/uracil (flame retardant [FR] wood), which was environmentally friendly, high strength and fire‐resistant. The three‐point bending test performance was basically unchanged, compressive strength was increased by 15.3%. The peak heat release rate, total heat release, smoke production rate, and total smoke production of FR wood were reduced up to 41%, 30%, 61%, 56%, respectively, compared with the natural wood. Limiting oxygen index value of FR wood can reach 31.8%, and UL‐94 V‐0 rating can be reached. These results suggested that wood/PA/uracil could be promising green construction applications.

通过使用天然植酸和尿嘧啶进行一步处理的木材，可增强机械性能和阻燃性

木材由于其独特的优异特性一直在建筑工程和装饰中保持重要地位，但其易燃性限制了其各种应用。在本研究中，将植物种子中的植酸（PA）和核糖核酸（RNA）中的尿嘧啶（U）制成水溶液，而天然木材仅通过在水溶液中物理渗透即可获得木材/ PA /尿嘧啶（阻燃[FR]木材），它是环保，高强度和耐火的。三点弯曲试验性能基本保持不变，抗压强度提高了15.3％。与天然木材相比，FR木材的峰值放热率，总放热，烟雾产生率和总烟雾产生率分别降低了41％，30％，61％，56％。FR木材的极限氧指数值可以达到31.8％，可以达到UL-94 V-0等级。这些结果表明，木材/ PA /尿嘧啶可能是有前途的绿色建筑应用。
