阻燃型包装纸板材料的阻燃剂制备及性能研究

Preparation of a Flame Retardant Agent for Flame Retardant Type Packaging Paperboard and Its Properties

目的制备一种阻燃性能较佳的包装纸板阻燃剂,并研究分析其阻燃性能。方法在安全环保及阻燃剂在纸制品方面应用研究的基础上,选用磷酸胍(GP)、氢氧化镁(MH)和羟甲基纤维素(CMC)作为安全环保阻燃剂,通过对磷酸胍单组分及多组分复配配方的阻燃效果进行试验和筛选,分析探讨并确定安全环保阻燃剂的最佳配方及制备方法。结果磷酸胍阻燃液质量分数为10%,氢氧化镁质量浓度为20 g/L,CMC质量浓度为10 g/L,溶剂为水,涂覆温度为60℃时,制备的阻燃性包装纸板材料的阻燃性能最佳。结论该配方涂覆B瓦单瓦楞纸板时,能使纸板达到较好的难燃等级。

Objective To prepare a flame retardant agent for packaging paperboard with good flame retardant properties, and analyze its flame retardant properties. Methods Based on the safe and green properties as well as the application study of flame retardants in paper products, GP, MH and CMC were selected to prepare flame retardants. Tests and screening were conducted using GP as single composition and the blended formula for their flame-retardant performance, and the optimal formula as well as the preparation method for the safe and green flame retardant were analyzed and determined. Results The flame retardant paperboard packaging materials with the best performance were prepared when the concentration of the flame retardant Guanidine Phosphate（GP） was 10%, the dosages of magnesium hydroxide and CMC were 20 g/L and 10 g/L, the solvent was water, and the coating temperature was 60 ℃. Conclusion When B watts single corrugated cardboard was coated with flame retardant prepared using this formula, higher fire retardant grade was achieved.
