Abstract As a modifier, silica sol was introduced into the traditional melamine cyanurate (MCA) preparation process and therewith modified MCA (mMCA) was prepared. mMCA was blended with nylon 6 (PA 6) to prepare flame retardant PA 6 composites and the flame retardant properties were investigated. The results show that silica sol may contribute to the enhancement of flame retardant property. With the increase of silica sol content, the limited oxygen index (LOI) of PA 6/mMCA composites increase firstly
and then decrease, and the self-extinguishing time decreases. In the presence of silica sol, the amount of drippings can be reduced, the formation of non-flame dripping increases and the char structure can be improved.
