Abstract:
Disclosed in the present invention are a flame-retardant nylon composite material and an application thereof. The flame-retardant nylon composite material comprises the following components: 55-80 parts of a nylon resin, 1-30 parts of red phosphorus, and 0.01-2 parts of a phenolic substance. According to the present invention, by adding a small amount of phenolic substance into the red phosphorus flame-retardant nylon composite material, phosphorus can be effectively prevented from being separated out and the separate-out amount of hydrogen phosphide can be reduced to 30 ppm or below; and meanwhile, a good electric property can be kept, so that the flame-retardant nylon composite material is suitable for the fields of connectors, contactors and the like in electric products.
