Abstract:
Polybenzoxazine, a new class of phenolic thermosetting resins, has been studied for aluminum adhesive. In this work, the mechanical property of polybenzoxazine based on aniline and on methylamine was determined by lap shear test. It was found that the incorporation of a small amount of amine terminated butadiene acrylonitrile (ATBN) improved the strength of polybenzoxazine adhesive. The shear strength of polybenzoxazine based on methylamine adhesive (B-m adhesive) was investigated at 150 °c. The result showed that B-m adhesive has a potential to be a high temperature adhesive. The corrosion protection of B-a on copper in humid environment was studied by Fourier transform infrared reflection-absorption spectroscopy (FTIR-RAS). It was found that B-a can protect copper from corrosion in humid environment.
