为解决次磷酸铝(AHP)水溶性高、热稳定性差等问题,采用原位聚合法,以聚脲甲醛(PUF)为壁材,阻燃剂AHP为芯材,制备了聚脲甲醛次磷酸铝(PUFAHP)微胶囊。通过红外光谱、扫描电镜和粒径分析对PUFAHP的结构和形貌进行了表征。AHP粒子表面包覆一层PUF树脂后,棱角被淡化,粒径变大。水溶性和水接触角测试结果表明,AHP经过PUF树脂微胶囊化改性后疏水性得到增强,水溶性明显降低。热失重分析结果表明,所制备的PUFAHP微胶囊具有优良的热稳定性。
- Abstract:

Polyurea formaldehyde aluminum hypophosphate microcapsules (PUFAHP) were prepared with polyurea formaldehyde (PUF) as the wall material and flame retardant aluminum hypophosphate (AHP) as the core material by in-situ polymerization,since AHP possesses the high water solubility and poor thermal stability. The structure and morphology of PUFAHP were characterized by Fourier transform infrared spectrometry,scanning electron microscopy and particle size test. After the AHP particles were coated with PUF resin,their edges and angles were desalinated, and the particle sizes became larger. The water-solubility test and water contact angle test indicate that the hydrophobicity of AHP increases and the water solubility decreases significantly after microencapsulation of PUF resin. Thermogravimetric analysis shows that PUFAHP microcapsules have excellent thermal stability.
