Abstract: |
The application of pre-modified lamellar clay[SBR/clay (dosage ratio 100/80 )nanocomposite] in brominated butyl rubber (BIIR) was studied. The results showed that,uniform nano
dispersion of the pre-modified lamellar clay in BIIR was achieved,and the interaction force between the lamellar clay and rubber molecular chain increased. Compared with the compound without the pre-modified lamellar clay,the crosslinking density of the pre-modified lamellar clay/BIIR composite decreased,the optimum curing time was shortened,the tensile strength,elongation at break and permanent deformation at break increased,the loss factor at 60 ℃ decreased,the air tightness was significantly improved.The composite
had a high performance cost ratio. |
