The present invention discloses a highly efficient red phosphorus masterbatch with low phosphine release, comprising the following components by weight: 5 to 15 parts low-temperature resin, 15 to 20 parts red phosphorus powder, synergist for red phosphorus 20–60 parts by weight, adsorbent 1–10 parts by weight, lubricant 1–2 parts by weight.
The prepared red phosphorus flame retardant exhibits excellent flame retardancy, low phosphine release, and a simple preparation process, offering promising application prospects.
The invention also proposes a preparation method for the high-efficiency red phosphorus masterbatch comprising the following steps:
uniformly blending all components of the masterbatch; feeding the resulting mixture into a twin-screw extruder; undergoing plasticization and blending at 80°C to 140°C; followed by extrusion and hot-cut pelletization to obtain the low phosphine release, high-efficiency red phosphorus masterbatch.
