摘　　要：针对纸张易燃的问题,基于钠基蒙脱土的吸水膨胀及钠离子交换特性,分别用钠基蒙脱土吸附尿素(UM)、磷酸二氢铵(ADP)和三聚氰胺(MEL)制成新型复合阻燃剂,并涂覆于纸张表面制备阻燃纸张。通过傅里叶变换红外光谱(FTIR)、热重分析(TGA)、垂直燃烧测试、力学性能测试等对阻燃纸张的微观结构、阻燃性能和力学性能进行分析。结果表明,相比于空白纸张,利用MMT-UM、MMT-ADP和MMT-MEL涂覆得到的阻燃纸张,其阻燃性能得到显著提升,热稳定性得到增强。且随阻燃剂用量的增加,制备的阻燃纸张的炭化长度明显变短,断后伸长率、撕裂强度和挺度等力学性能都有不同程度的提升。Based on the water-absorbing and swelling properties of sodium montmorillonite and the sodium ion exchange properties of sodium montmorillonite,a new type of composite flame retardant was made from sodium montmorillonite by adsorption of urea(UM),ammonium dihydrogen phosphate(ADP),and melamine(MEL),respectively,which was coated on the surface of the paper to prepare flame-retardant paper.The microstructure,flame retardancy and mechanical properties of flame-retardant paper were analyzed by Fourier transform infrared spectroscopy(FTIR),thermogravimetric analysis(TGA),vertical combustion test and mechanical test.Research shows that,compared to blank paper,the flame-retardant paper obtained by coating with MMT-UM,MMT-ADP and MMT-MEL has significantly improved flame-retardant properties and enhanced thermal stability.With the increase of flame retardant dosage,the carbonization length is obviously shorter,and the mechanical properties such as elongation at break,tear strength and stiffness of the prepared flame retardant paper were improved to different degrees.
