摘要: 在表面活性剂三乙醇脏存在的条件下,以Zn( NO3)2  • 6H2O和民BO3 为原料,利用水热反应制备出分散均匀的4ZnO • B2O3 • H2 O微米棒.利用x-射线粉末衍射、热重差示扫描量热、红外及扫描和透射电镜对微米棒的物相、组成、表面结构及形貌进行了分析.研究表明:所制备的棚酸辞微米棒分散均匀,直径为0.2 -0.5μm ,长度为5 -10μm;400℃时,添加10% (质量分数)的棚酸辞微米棒可使杨木粉的残炭量比未添加棚酸铸的提高18.69% ,极限氧指数达43.2 ,说明明酸锌微米棒具有良好的阻燃性能.

Abstract:

Well-dispersed 4ZnO • B2O3 • H2 Omicrorods were prepared via the hydrothermal synthesis from zinc nitrate and boric acid , with triethanolamine as the surfactant. The phase , composition , surface structure and morphology of the product were then analyzed by means of powder X-ray diffraction , TG-DSC , IR , SEM and TEM. The results indicate that (1) The diameter and length of the well-dispersed product are 0.2 - 0.5μm and 5 -10μm ,respectively; (2) as for the poplar wood powder treated with 10% of zinc borate microrods , the limit oxygen index reaches 43. 2 and the residual charcoal ratio increases by 18. 69%, as compared with that of the powder without zinc borate. The results clearly show that zinc borate microrods are of fine flame-retardant properties.
