    • PROBLEM TO BE SOLVED: To provide a surface-treated plate which has good processability, high corrosion resistance, high dew condensation/whitening resistance or the like.SOLUTION: A surface-treating agent contains a water-dispersible polyurethane resin (A), and 5-50 parts by mass of a rust-preventive agent (B), 10-150 parts by mass of colloidal silica (C) having been treated with a silane coupling agent, and 30-110 parts by mass of a basic alkali silicate (D), each amount based on 100 parts by mass of the total solid content in the water-dispersible polyurethane resin (A). The rust-preventive agent (B) contains a titanium compound (b1) and an organic phosphoric acid compound (b2), and further contains at least one kind selected from among a vanadium compound (b3) and a zirconium compound (b4).
    • 要解决的问题:提供一种表面处理板,其具有良好的加工性,高耐腐蚀性,高结露/耐白化性等。 解决方案:表面处理剂含有水分散性聚氨酯树脂(A)和5-50质量份防锈剂(B),10〜150质量份胶态二氧化硅(C) 已经用硅烷偶联剂处理,和30-110质量份碱性碱式硅酸盐(D),每种量基于水分散性聚氨酯树脂(A)中的总固体含量100质量份。 防锈剂(B)含有钛化合物(b1)和有机磷酸化合物(b2),并且还含有选自钒化合物(b3)和锆化合物(b4)中的至少一种。 版权所有(C)2012,JPO&INPIT
