Abstract

The invention provides a high-heat-resistance halogen-free flame-retardant polyamide compound. The high-heat-resistance halogen-free flame-retardant polyamide compound is characterized by being prepared from the following raw materials, by weight: 10 to 60 parts of aliphatic polyamide, 5 to 30 parts of aromatic polyamide, 10 to 30 parts of a halogen-free flame retardant, 1 to 10 parts of phenolicresin, 10 to 50 parts of a glass fiber, and 0.1 to 0.5 part of an antioxidant; the phenolic resin is linear phenolic resin, and the molecular weight of the phenolic resin is 1000-4000 g / mol. Accordingto the high-heat-resistance halogen-free flame-retardant polyamide compound and the preparation method thereof disclosed by the invention, the halogen-free flame-retardant polyamide compound is endowed with excellent ageing resistance, flame retardance and mechanical property through the combined synergistic effect of multiple components including the phenolic resin, the antioxidant, the aromaticnylon and the halogen-free flame retardant.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high heat-resistant halogen-free flame-retardant polyamide compound and a preparation method thereof. Background technique [0002] Halogen-free flame retardant polyamide has excellent flame retardancy, mechanical properties, heat resistance, low smoke and environmental protection, and is widely used in the fields of electronics, automobiles and aerospace. At present, industries such as electronic appliances and new energy are showing the development trend of high current, thin wall, miniaturization and integration. High current, miniaturization and integration will cause the local temperature of the part to be too high, and plastic will occur Thermal oxidation leads to a sharp decrease in its mechanical properties, which in turn leads to functional failure of the part and, in severe cases, a safety accident. Therefore, this puts forward more stringent requirements o...
