High-toughness and precipitation-resistant red phosphorus flame-retardant nylon composite material and preparation method thereof

The invention discloses a high-toughness and precipitation-resistant red phosphorus flame-retardant nylon composite material, which is prepared from the following raw materials in percentage by mass: 39 to 47 percent of nylon resin, 23 to 27 percent of glass fiber, 12 to 16 percent of phosphorus flame retardant, 2.0 to 4.0 percent of flame-retardant synergist, 1.0 to 3 percent of acid acceptor and 8.0 to 15 percent of flexibilizer. The material has high mechanical strength, meets the requirement for high toughness, and has flame retardance and low acid precipitation performance. 本发明公布一种高韧性、耐析出红磷阻燃尼龙复合材料，包含以下质量百分比的原料：尼龙树脂39~47%、玻璃纤维23-27%、磷系阻燃剂12~16%、阻燃协效剂2.0~4.0%、吸酸剂1.0~3%、增韧剂8.0~15%。该材料具有较高机械强度的同时满足高韧性要求，同时赋予阻燃、低酸析出性能。
