SHOE PRESS BELT FOR PAPERMAKING |
摘要 |
<p>A belt for papermaking shoe presses 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'-methylenebis(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-ß-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.</p> |
