摘要
Abstract
Heat damp test was carried out according to the GJB150.9 standard.The laminated glass samples with polyurethane（PU） and polyvinylbutyral（PVB） as interlayer respectively were tested under heat damp environment,which optical properties were changed evidently in different times,such as the transparence decreased 2.2% and haze increased 11.6%.And then,the samples were placed for a long time in natural environment.It is found that the haze of laminated sample with PU can＇t comeback,while sample with PU can.Accelerated aging was carried out by submerging the samples in 60±1℃ water for some time,the sample absorbed enough water were dried entirely.With the help of Fourier transform infrared（FTIR） spectroscopy and subtraction spectra,the results are shown that new structures are formed between the interaction of PU and water.关键词
