AI Technical Summary
The existing acrylic rubber compositions used in cross-linked rubber laminates for fuel hoses have limited crosslinking adhesiveness with fluororubber compositions, which affects the performance and durability of the fuel hoses.
Incorporating a heteroatom-containing alcohol, specifically an amino alcohol, into the acrylic rubber composition, along with a carboxyl group-containing acrylic rubber and a polyvalent amine compound, enhances the crosslinking adhesiveness with the fluororubber composition.
The modified acrylic rubber composition exhibits excellent crosslinking adhesiveness with the fluororubber composition, leading to improved mechanical properties and durability of the cross-linked rubber laminate, particularly in applications like fuel hoses.
