摘要:
Disclosed is a shoe press belt (10) which comprises a reinforcing fibrous base material (6) embedded in a polyurethane layer, and has an outer circumference layer (2a) and an inner circumference layer (2b) each formed with a polyurethane. The polyurethane layer constituting the outer circumference layer (2a) comprises a polyurethane which is cured by the reaction of an urethane prepolymer (A) with a curing agent mixture (B). The urethane prepolymer (A) is produced by reacting an isocyanate compound selected from p-phenylene-diisocyanate and 4,4′-methylenebis(phenylisocyanate) with a polytetramethylene glycol and has an isocyanate group at its terminal. The curing agent mixture (B) comprises 1,4-butanediol and an aromatic polyamine having an active hydrogen group (H). The shoe press belt has excellent wear resistance, cracking resistance and bending fatigue resistance.
