Abstract

The invention discloses a halogen-free and highly-heatproof resin composition for a copper-clad board. 100 PHR of organic solids of the composition mainly comprise 5-60 PHR of polystyrene-containing main chain benzoxazine resin, 20-50 PHR of highly-heatproof epoxy resin, 5-30 PHR of other curing agents, 0.1-10 PHR of toughened resin, 10-30 PHR of a phosphorus-containing fire retardant, 40-150 PHRof an inorganic filler, 0.01-1 PHR of a curing promoter, 0.01-1 PHR of a silane coupling agent, and a proper amount of a solvent. The copper foil-clad laminated board produced from the composition hasthe advantages of excellent dielectric properties, high glass transition temperature, low coefficient of thermal expansion, high heatproof property, good flame retardancy and excellent PCB processingperformances.

Description

technical field [0001] The invention relates to the technology in the field of copper-clad laminates, in particular to a halogen-free high heat-resistant resin composition for copper-clad laminates, which has excellent dielectric properties, high glass transition temperature, low thermal expansion coefficient, high heat resistance Thermal, excellent machinability and other properties, can meet the high frequency and high speed PCB multilayer board process. Background technique [0002] In order to make the flame retardant reach UL94V0 level and prevent the circuit from causing fire due to short circuit, traditional printed circuit laminates usually add brominated flame retardants, such as tetrabromobisphenol A, to the composition, but halogenated flame retardants Or when the resin burns, it will generate toxic and corrosive gas, which will cause great harm to the human body and the surrounding environment. In particular, the European Union officially implemented two environ...
