Problems solved by technology

[0009] The resin system currently used for copper foil substrates and printed circuit boards is epoxy resin, generally using standard FR4 substrates, and its main component is brominated epoxy resin made of bisphenol A epoxy resin and tetrabromobisphenol A , using dicyandiamide as a curing agent, and then adding accelerators and solvents, the disadvantages of this epoxy resin composition are that the glass transition temperature (Tg) is too low (120-140°C) and the heat resistance is poor. Using multifunctional epoxy resin instead of bisphenol A epoxy resin can improve the disadvantage of low glass transition temperature (Tg) by using the increase of crosslinking density, but it does not contribute much to improving heat resistance and electrical properties

Abstract

The invention provides an epoxy modified maleic anhydride copolymer prepolymer with a structural formula shown as formula (I) and a resin composition containing the same. The resin composition using the epoxy modified maleic anhydride copolymer prepolymer with a structural formula shown as formula (I) has good heat resistance and excellent electrical properties, and the viscosity does not rise along with time variation to affect the quality of a semi-cured film. At the same time, the resin composition is suitable for making semi-cured films and copper clad laminates, and can be applied to general or high frequency printed circuit boards.

Description

technical field [0001] The invention relates to an electronic material, in particular to an epoxy-modified maleic anhydride copolymer prepolymer and its resin composition, preparation method and application. Background technique [0002] Epoxy resin has been widely used in copper clad laminate (CCL) and printed circuit board (PCB) for many years, the main reason is that epoxy resin and reinforcing materials such as glass fiber cloth, glass fiber mat , paper base, etc. have good bonding strength; and there will be no volatile components during curing, and the molding shrinkage is small. The copper foil substrate produced has excellent mechanical strength, electrical insulation, chemical resistance, good dimensional accuracy and is easy to process. It has become the most important raw material in printed circuit boards. [0003] At present, the copper foil substrates used in printed circuit boards are mainly FR-4 boards in terms of quantity and technical level. It is necessa...
