Low-precipitation red-phosphorus flame-retardant nylon material and preparation method and application thereof

The invention discloses a low-precipitation red-phosphorus flame-retardant nylon material and a preparation method and application thereof. The low-precipitation red-phosphorus flame-retardant nylon material is prepared from, by mass, 30%-80% of nylon resin, 5%-30% of red-phosphorus flame retardant, 0.1%-2% of red-phosphorus stabilizer, 0-10% of toughening agent, 10%-50% of reinforcing filler and 0.1%-5% of other additives. According to the low-precipitation red-phosphorus flame-retardant nylon material, the red-phosphorus flame retardant is adopted to be blended with other components, the red-phosphorus flame-retardant nylon material with good stability is prepared by adjusting the proportion of all the components, the red-phosphorus flame-retardant nylon material is low in phosphorus precipitation in a long-term high-temperature and high-humidity environment, and therefore corrosivity to metal and dies is reduced; meanwhile, the red-phosphorus flame-retardant nylon material has the good flame retardancy, el
