[0053] Preparation of Zirconium Phosphonate 1#
[0054] Accurately weigh 20.3g of zirconium oxychloride and dissolve it in 200mL of deionized water to make an aqueous solution of zirconium oxychloride, and accurately weigh 21g of glyphosate and dissolve it in 3000mL of deionized water to make an aqueous solution of glyphosate. Add 40 g of hydrofluoric acid with a concentration of 40% to the zirconium oxychloride aqueous solution, stir and mix the zirconium oxychloride aqueous solution and the glyphosate aqueous solution in a flask, keep stirring, heat the reaction in a water bath at 80° C. for 6 hours, centrifuge the product, and use Wash with deionized water until the supernatant is neutral, dry at 90°C, and grind the sample into powder to obtain 28.7 g of zirconium glyphosate phosphonate, which is denoted as ZrGP1, and its X-ray diffraction (XRD) spectrum is shown in figure 1 , the scanning electron microscope (SEM) photo see figure 2 .
[0055] Preparation of Silver Ammo...
Embodiment 1
[0062] 7 parts of intumescent flame retardant, 7 parts of silver ammonium phosphomolybdate intercalated zirconium phosphate, 4 parts of ceramic fiber powder, 2 parts of silicone masterbatch MB50-001 (Dow Corning), 0.8 parts of antioxidant 1010, 36 parts of white oil #0.5 parts and 78.5 parts of polypropylene 6012 (Sinopec) were weighed and mixed uniformly in proportion, then added to a twin-screw extruder with a length-to-diameter ratio of 38:1, melted, extruded and granulated to obtain the product. The product performance is shown in Table 2.
Embodiment 2
[0064] 9 parts of intumescent flame retardant, 3 parts of silver ammonium phosphomolybdate intercalated zirconium phosphate, 2 parts of ceramic fiber powder, 3 parts of silicone masterbatch MB50-001 (Dow Corning), 0.5 parts of antioxidant 1010, 36 parts of white oil #0.5 parts and 82 parts of polypropylene 6012 (Sinopec) were weighed and mixed uniformly in proportion, then added to a twin-screw extruder with a length-to-diameter ratio of 38:1, melted, extruded and granulated to obtain the product. Product properties are shown in Table 2.
