Study On Modified SBS Adhesive

Through the s olut ion a nd me lti ng grati n g modi fic a tion on t he SBS by organic silicon monomers, modified SBS adhesive was prepared. After every reaction conditions were re viewed, the best modification adhes ive for mul a s we re obtai ne d. The gra ft rea cti on was de monstra ted by infrar ed spectr osc opy. The t her mal decomposition te mperature and the glass inversion temperature of the mo dified product we re det e r mi n ed b y t he t h er mo - gra vi me t ri c analysis method and the DSC test me thod, respectively. Tests of wa ter resi sta nce, acid and al kali resi stance, atmo spheric aging resi stance and salt fog resist anc e of t he modified SBS adhesive were carried on. The tests results obtained that the performances of modi fied SBS by organic silicon have been changed. The thermo-stability, compatibility performance of SBS and CR rubber she e t , a nd a dh e sio n pr opert y, water re s ista nce , aci d a nd al kal i resi stance, atmo spheric aging resi stance and salt fog resist anc e of t he modified SBS adhesive have been improved.
