Beschreibung
Zusammenfassung:	A metal surface treatment agent for a zinc-plated steel material contains organic resin particles (A), silicon oxide particles (B), lithium silicate (C), an organic titanium compound (D) and an epoxy group-containing compound (E), wherein the organic resin particles (A) are obtained by modifying a base resin with a silane coupling agent (A-1) and a polyfunctional epoxy group-containing compound (A-2), and have silanol groups and/or alkoxysilyl groups, wherein the total number of moles of elemental silicon, calculated in terms of SiO2, contained in the silicon oxide particles (B) and the lithium silicate (C) is 40-70 times the number of moles of elemental lithium, calculated in terms of Li2O, contained in the lithium silicate (C), and wherein the ratio of the mass of lithium silicate (C) relative to the mass of elemental titanium contained in the organic titanium compound (D) is 0.2-200. 本发明的镀锌钢材用的金属表面处理剂含有有机树脂颗粒(A)、氧化硅颗粒(B)、硅酸锂(C)、有机钛化合物(D)及含环氧基化合物(E)，前述有机树脂颗粒(A)为通过硅烷偶联剂(A-1)和含多官能环氧基化合物(A-2)使基体树脂改性的树脂颗粒，且为具有硅
