Abstract:
The present invention relates to an epoxy resin composition for a copper clad laminate, and an application of the epoxy resin composition. The epoxy resin composition may be used for the preparation of pre-pregs and copper clad laminates. By using brominated epoxy resin such as a low bromine epoxy resin and a high bromine epoxy resin as bromine sources and taking a phosphorus-containing phenanthrene-type compound as a phosphorus source, and adjusting the proportions of the brominated epoxy resins and the phosphorus-containing phenanthrene-type compound within the epoxy resin composition, the bromine content is controlled at 5-12%, the phosphorus content is controlled at 0.2-1.5%, and the flame retardancy achieves the level of UL94 V-0. Compared to pure bromine flame retardant copper clad laminates, the heat resistance is higher, and a higher CTI value is achieved. Compared to pure phosphorus flame retardant copper clad laminates, the moisture absorption is low, and the adhesion performance and process operability required for printed circuit substrates are provided. Compared to the use of a large amount of aluminum hydroxide in traditional high CTI sheet material, the present invention achieves CTI>600V using a small amount of aluminum hydroxide or without using aluminium hydroxide.
