ABSTRACT:
A papermaking shoe press belt is formed of a reinforcing fiber base material and a polyurethane layer integrated with each other. The reinforcing fiber base material is embedded in the polyurethane layer. The papermaking shoe press belt includes, as the polyurethane layer, a polyurethane layer obtainable by curing a composition composed in combination of a urethane prepolymer and one or more curing agent. The urethane prepolymer is obtainable by reacting a p-phenylene diisocyanate compound with a long-chain polyol. The at least one curing agent is selected from 4,4′-methylene bis(2,6-diethyl-3-chloroaniline), 4,4′-methylene bis(2-chloroaniline), methylene bis(2-ethyl-6-methylaniline), 4,4′-methylene bis(2-ethylbenzeneamine), methylene bis(2,3-dichloroaniline), 4,4′-methylenedianiline, 3,5-dimethylthiotoluene-2,4-diamine, 3,5-dimethylthiotoluene-2,6-diamine, 3,5-diethyltoluene-2, 4-diamine, 3,5-diethyltoluene-2,6-diamine, polytetramethylene oxide di-p-aminobenzoate, poly(tetramethylene/3-methyl tetramethylene ether)glycol bis(4-aminobenzoate) , trimethylene bis(4-aminobenzoate) and isobutyl 4-chloro-3,5-diaminobenzoate.
