摘要： A high-CTI and halogen-free epoxy resin composition for copper-clad plates and uses thereof is provided. The formula of the high-CTI and halogen-free epoxy resin composition for copper-clad plates comprises 100˜140 parts of halogen-free phosphorous epoxy resin, 10˜35 parts of dicyclopentadiene phenolic epoxy resin, 32˜60 parts of benzoxazine, 1˜5 parts of phenolic resin, 0.05˜0.5 parts of accelerants; and 25˜70 parts of fillers, by weight. The copper-clad plates, prepared according to embodiments of the present invention, can reach the requirements of high CTI (CTI≥500V), high heat resistance (Tg≥150° C., PCT, 2 h>6 min) and the level of flame retardance of UL-94 V0, and they are widely used in the electronic materials of electric machines, electric appliances, white goods and so on.
