Description

technical field [0001] The invention belongs to the manufacture field of halogen-free flame retardants, and in particular relates to a modified nano-MCA composite flame retardant, a preparation method thereof and an application in preparing a halogen-free flame-retardant nylon composition for spinning. Background technique [0002] Melamine cyanurate (MCA) is a nitrogen-containing, halogen-free, environmentally friendly flame retardant, which is a white powdery solid. The preparation technology of MCA is very mature. The main method is to use melamine and cyanuric acid to generate directly. However, the particle size of MCA produced by this method is generally 1-50 μm. [0003] MCA is especially suitable for nylon 6 and nylon 66 without filler. The product is economical, efficient, and has excellent electrical and mechanical properties. At the same time, it has low toxicity, is safe for users, has good compatibility with the environment, and has good thermal stability, whi...
