摘要： The present invention provides a cleaning blade having an elastic body formed of a urethane elastomer, and a treated surface layer formed at least at a portion which comes into contact with a contact target of the elastic body. The treated surface layer is formed through impregnating a surface portion of the elastic body with a surface treatment liquid containing a bifunctional isocyanate compound, at least one polyol selected from a bifunctional polyol and a trifunctional polyol, and an organic solvent; or a surface treatment liquid containing an isocyanate group-containing compound having an isocyanate group at an end thereof, which compound is a reaction product of the bifunctional isocyanate compound with said at least one polyol selected from a bifunctional polyol and a trifunctional polyol, and an organic solvent, and curing the surface treatment liquid. The difference between the nitrogen concentration at the surface of the treated surface layer and the nitrogen concentration in the elastic body at a depth of 0.5 mm from the surface of the treated surface layer is 0.02 to 0.15 mass%.
摘要翻译：本发明提供一种清洁刮板，其具有由聚氨酯弹性体形成的弹性体以及至少在与弹性体的接触目标接触的部分处形成的经处理的表面层。处理过的表面层通过用含有双官能异氰酸酯化合物，至少一种选自双官能多元醇和三官能多元醇的多元醇和有机溶剂的表面处理液浸渍弹性体的表面部分而形成; 或含有在其末端具有异氰酸酯基的含异氰酸酯基的化合物的表面处理液，该化合物是双官能异氰酸酯化合物与选自双官能多元醇和三官能多元醇中的至少一种多元醇的反应产物，有机溶剂，并固化表面处理液。处理过的表面层表面处的氮浓度与处理过的表面层表面0.5mm深度处的弹性体中的氮浓度之差为0.02至0.15质量％。
