ABSTRACT:
A belt for papermaking shoe press is provided which comprises a reinforcing fibrous base (6) and a polyurethane layer (2) united therewith, the reinforcing fibrous base (6) having been embedded in the polyurethane layer (2). The belt includes a polyurethane layer obtained by curing a mixture comprising: a urethane prepolymer obtained by reacting a polyisocyanate compound selected among p-phenylene-diisocyanate, 4,4′-methylene-bis(phenyl isocyanate), and tolylene-diisocyanate with a polyol compound selected among polypropylene glycol, polytetramethylene glycol, and a polycarbonate diol; a hardener selected among an aliphatic diol compound, hydroquinone-bis-β-hydroxyethyl ether, and organic polyamine compound; and an aliphatic triol compound. Due to this layer, the shoe press belt for papermaking is excellent in wearing resistance and flexing fatigue resistance.
