Halogen-free resin composition containing ester curing agent for high-frequency and high-speed printed-circuit board

The invention discloses a halogen-free resin composition containing an ester curing agent for a high-frequency and high-speed printed-circuit board. The halogen-free resin composition is prepared from the following ingredients in parts by weight: 9 to 12 parts of phenolic epoxy resin, 10 to 14 parts of phosphorus-containing epoxy resin, 15 to 25 parts of benzoxazine, 0 to 10 parts of active esters, 5 to 15 parts of phosphorus-containing environment-friendly halogen-free flame retardant resin, 0.5 to 1.5 parts of accelerants and 15 to 25 parts of silicon dioxide molten powder. The halogen-free resin composition containing the ester curing agent for the high-frequency and high-speed printed-circuit board solves the problem of deficiency of certain performance of a laminated board made from resin composition with single ingredients; the laminated board made from the composition has excellent dielectric property, thermal expansion coefficient, good moisture and heat resistant performance, good mechanical processing performance, good flame retardant performance and the like.
