Embodiment 1
[0026] (1) Add 0.01mol of tin tetrachloride and 0.02g of sodium dodecylbenzenesulfonate into a 100mL deionized water beaker containing 20g of nano-calcium carbonate, and sonicate for 20 minutes until completely dissolved;
[0027] (2) Disperse 0.01mol of zinc chloride in 60mL of deionized water, sonicate for 10 minutes until the dispersion is uniform, add the dispersion liquid dropwise into the beaker of step (1), and stir magnetically to make it evenly mixed;
[0028] (3) Dissolve 0.002mol of sodium hydroxide in 10mL of deionized water, sonicate for 10 minutes until completely dissolved, add the solution dropwise into the beaker of step (2), and stir magnetically to make it evenly mixed;
[0029] (4) Put the mixture in step (3) at 50°C for coating reaction for 8 hours, take out the precipitate, wash it with deionized water for 5 times, and dry the product after washing to obtain a low-cost coated flame retardant and smoke suppressant;
