Embodiment 1
[0020] Embodiment 1: A kind of flame-retardant plant fiber, is prepared by the following method:
[0021] ①Add 100mL of magnesium chloride solution with a concentration of 0.8mol / L to a three-necked flask, heat and stir, control the temperature at 50°C, add 3g of hardwood fiber and 0.04g of ultrafine silica, and stir rapidly for 20min;
[0022] ② Add 200mL of ammonia water with a concentration of 2%, and continue to stir rapidly for 10min;
[0023] ③ After filtering the broad-leaved wood fibers, wash them with clean water to obtain flame-retardant plant fibers;
[0024] ④Copy the flame-retardant plant fiber with a copying machine and make it quantitatively 45g. m -2 flame retardant paper.
Embodiment 2
[0025] Embodiment 2: A kind of flame-retardant plant fiber, is prepared by the following method:
[0026] ①Add 100mL of magnesium chloride solution with a concentration of 1.0mol / L into a three-neck flask, heat and stir, control the temperature at 60°C, add 3g of hardwood fiber and 0.06g of ultrafine silica, and stir rapidly for 30min;
[0027] ② Add 200mL of ammonia water with a concentration of 2%, and continue to stir rapidly for 15min;
[0028] ③ After filtering the broad-leaved wood fibers, wash them with clean water to obtain flame-retardant plant fibers;
[0029] ④Copy the flame-retardant plant fiber with a copying machine and make it quantitatively 50g. m -2 flame retardant paper.
Embodiment 3
[0030] Embodiment 3: A kind of flame-retardant plant fiber, is prepared by the following method:
[0031] ①Add 100mL of magnesium chloride solution with a concentration of 1.2mol / L to a three-neck flask, heat and stir, control the temperature at 70°C, add 3g of hardwood fiber and 0.04g of ultrafine silica, and stir rapidly for 30min;
[0032] ② Add 200mL of ammonia water with a concentration of 2.5%, and continue to stir rapidly for 20min;
[0033] ③ After filtering the broad-leaved wood fibers, wash them with clean water to obtain flame-retardant plant fibers;
[0034] ④Copy the flame-retardant plant fiber with a sheeter to make a quantitative 60g. m -2 flame retardant paper.
