Abstract:
The present invention provides a halogen-free flame retardant resin composition, and, a prepreg, a laminate, and a laminate for printed circuit that are made from the halogen-free flame retardant resin composition. The halogen-free flame retardant resin composition comprises: (A) 40-80 parts by weight of the mixture of a phenoxyphosphazene compound (A1) and a dihydrobenzoxazine ring-containing compound (A2), and, the weight ratio between the phenoxyphosphazene compound (A1) and the dihydrobenzoxazine ring-containing compound (A2) being between 1:10 and 1:2; (B) 15-45 parts by weight of a polyepoxy compound; (C) 5-25 parts by weight of a phenolic resin type hardener; and (D) 0.1-1 parts by weight of an imidazole type compound as the curing accelerator. The prepreg, the laminate, and the laminate for printed circuit that are made from the halogen-free flame retardant resin composition provided by the present invention, have excellent flame retardancy, as well as has high glass transition temperature (Tg), high thermal resistance, high flexural strength, high reliability, low dielectric dissipation factor, low moisture, low C.T.E, good chemical resistance, and good processability.
