Embodiment 1
[0028] In a four-necked flask, 2-sulfonic acid group-4-β-sulfate ethyl sulfonyl aniline (sulfonated para-ester) and dimethylformamide (DMF) were mixed at a mass ratio of 1:10 at room temperature at 25 Fully dissolved at ℃, adding formic acid as a catalyst.
[0029] Raise the temperature to 80°C, then drop γ-glycidyl etheroxypropyltrimethoxysilane (KH-560) with a molar ratio of 2.1 times the sulfonated para-ester into the four-necked flask at a rate of 1 drop / second, and continuously Stir. After the dropwise addition, nitrogen gas was introduced, and the reaction was continued at 80° C. for 3 h under mechanical stirring, and then the temperature was lowered to stop the reaction. After the reaction is over, the mixed liquid is distilled out of the organic solvent DMF under reduced pressure, and a viscous light yellow liquid is obtained after distillation, which is a flame retardant for natural fibers.
[0030] After the viscous light yellow liquid is tested by an infrared inst...
