摘要
在表面活性剂三乙醇胺存在的条件下,以Zn（NO3）2.6H2O和H3BO3为原料,利用水热反应制备出分散均匀的4ZnO·B2O3·H2O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：所制备的硼酸锌微米棒分散均匀,直径为0.2-0.5μm,长度为5-10μm;400℃时,添加10%（质量分数）的硼酸锌微米棒可使杨木粉的残炭量比未添加硼酸锌的提高18.69%,极限氧指数达43.2,说明硼酸锌微米棒具有良好的阻燃性能.
Well-dispersed 4ZnO·B2O3·H2O microrods 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.
