The invention discloses a flame-retardant and high-heat-resistance resin composition, a copper clad laminate and a preparation method thereof. The flame retardant and high heat-resistant resin composition composed of resin, inorganic filler and curing accelerator is mixed with an appropriate amount of solvent to make resin composition glue, and the glass fiber cloth is impregnated. The temperature of the impregnated glass fiber cloth is 130 ℃ Bake in a drying tunnel at ~170℃ for 4 ~ 7min to obtain a prepreg; stack 3 ~ 25 layers of prepreg and attach copper foils on both sides, heat press at 160℃ ~ 250℃, 0.2 ~ 4MPa for 3 ~ 5h and thermoset into shape The glass fiber cloth copper clad sheet, that is, flame retardant and high heat resistant copper clad laminate. The flame-retardant and high-heat-resistant copper clad laminate prepared by using the flame-retardant and high-heat-resistant resin composition of the invention has good comprehensive performance, can be widely used in the field of printed circuit boards, and has strong practicability. |
