Embodiment Construction
[0023] 1. Preparation of microencapsulated red phosphorus powder
[0024] After removing yellow phosphorus and finely ground red phosphorus powder (particle size 50 μm), add zinc nitrate and ammonium phosphate under alkaline conditions, deposit a thin layer of zinc phosphate on the surface of red phosphorus powder, and then add phenol and formaldehyde, Silicone resin, reacting to produce composite coated red phosphorus powder of phenolic resin and silicone resin. The coated red phosphorus powder and nylon 6 are processed into red phosphorus masterbatch A with nylon 6 as the carrier resin through an extruder, and the phosphorus content of the red phosphorus masterbatch is 50%.
[0025] After removing yellow phosphorus and finely ground red phosphorus powder (particle size 50 μm), add zinc nitrate and boric acid under alkaline conditions, deposit a thin layer of zinc borate on the surface of red phosphorus powder, and then add epoxy resin and polyurethane after treatment Resin,...
