Abstract:
1. A high thermal-conductive, halogen-free and flame-retardant resin composition, based on total weight of the resin composition, comprising: (1) 5% to 70% of phosphorus-containing epoxy resin; (2) at most 50% of multifunctional or bifunctional epoxy resin, (3) 1% to 20% of curing agent; (4) 0.01% to 10% of accelerant; (5) at most 20% of inorganic powder for enhancing rigidity if the resin composition is cured, wherein the inorganic powder having an average diameter of 0.01-20 micron(s) is at least one selected from the group consisting of SiO (6) 5% to 85% of high thermal conductivity powder(s) having an average diameter of 0.1-10 micron(s) in form of dust, beads, fibers, chips or pieces, and having closest packed in highest density model by Horsfield packing model, wherein the high thermal conductivity powder is at least one selected from the group consisting of metal nitrides, metal oxides, carbides, corundum and aluminum powder; and (7) 0.01% to 10% of processing agents;
