IMPROVING ADHESION OF SILICONE RUBBER COATING TO POLYURETHANE SURFACE
提高聚氨酯表面硅橡胶涂层粘接性研究

Surface modification of polyurethane(PU) by appropriate treatment and introducing silane coupling agent to PU surface was used to improve the adhesion of PU to silicone rubber(SR).FTIR and X-ray energy spectrometer were employed to investigate the surface treatment and graft reaction of silane coupling agent,while surface morphology and properties of materials were characterized by scanning electron microscopy and water contact angle.Different PU/SR interfaces after oscillation and shear were compared as we...
