【摘要】：通过阳离子淀粉预处理氢氧化铝来制备阻燃植物纤维模塑墙体装饰材料。实验研究表明,阳离子淀粉预处理氢氧化铝后增大了其粒径;随着阳离子淀粉用量的增加,墙体装饰材料的灰分显著增加,采用预处理工艺得到的材料灰分增加得更明显,当阳离子淀粉用量为1.5%时,预处理中添加和普通植物纤维纸浆内添加的墙体装饰材料的灰分均达到最大值,分别为19.9%和19.3%。还探讨了预处理工艺对植物纤维墙体装饰材料挺度的影响,在提高阻燃剂留着率的同时,也对纸浆滤水性能进行了探讨,最后利用热重分析、SEM等方法探讨了阻燃机理。
[Abstract]:Flame retardant plant fiber molding wall decoration material was prepared by pretreatment of aluminum hydroxide with cationic starch. The experimental results show that the particle size of aluminum hydroxide pretreated with cationic starch increases. With the increase of cationic starch content, the ash content of wall decoration material increases significantly, and the ash content of the material obtained by pretreatment process increases more obviously, when the amount of cationic starch is 1.5%, The ash content of wall decoration materials added in pretreatment and common plant fiber pulp reached the maximum, 19.9% and 19.3%, respectively. The effect of pretreatment process on the stiffness of plant fiber wall decoration materials was also discussed. while improving the retention rate of flame retardant, the water filtration performance of pulp was also discussed. finally, the flame retardant mechanism was discussed by thermogravimetric analysis and SEM.
