Description
Summary:The aging behavior of polyurethane adhesive in medium was investigated and compared by means of scanning electronic microscopy（SEM）, infrared spectroscopy（IR）, interface analysis and shearing strength test. The experimental results show that the shear strength of polyurethane adhesive in salt water is decreased more quickly than that in water. Na^＋ and Cl^- ions could make the polyurethane adhesive age faster and the interface metal corrosion. The high temperature accelerates the diffusion of water molecule, Na^＋ and Cl^- ions and the degradation of the giant molecule.
