Patent ID: 7947154

Claim:
A shoe press belt for papermaking comprising a reinforcing fiber base and a polyurethane layer which are integral with each other, said reinforcing fiber base being embedded in said polyurethane layer, wherein said polyurethane layer comprises a polyurethane layer produced by curing a mixed composition of a urethane prepolymer (A) and a curing agent (B) having an active hydrogen group (H), said urethane prepolymer (A) obtained by reacting a polyisocyanate compound (a) comprising 55 to 100 molar % of a polyisocyanate compound selected from the group consisting of p-phenylene-diisocyanate, 4,4′-methylene-bis(phenyl isocyanate), and tolylene-diisocyanate, with a polyol compound (b) selected from the group consisting of polypropylene glycol, polytetramethylene glycol, and polycarbonate diol, and having a terminal isocyanate group, and said curing agent (B) comprising: 75 to 99.9 molar % of a curing agent (B1) selected from an aliphatic diol compound (B1 1 ) having the active hydrogen group (H) and a molecular weight in a range from 62 to 1,000, hydroquinone-bis-β hydroxylethyl ether and an organic polyamine compound (B1 2 ) having the active hydrogen group (H) and a molecular weight in a range from 108 to 1,300; and 25 to 0.1 molar % of an aliphatic triol compound (B2) having the active hydrogen group (H) and a molecular weight in a range from 92 to 134.
