내식성, 탈지 후 내식성, 도장 밀착성, 탈지 후 도장 밀착성, 내흑변성, 내결로 백화성, 처리제 안정성, 실기 조업성 등의 성능을 충족함과 함께, 내스택 백화성 및 내필라멘트 테이프성이 우수한 피막을 형성 가능한 아연 도금 강재용 또는 아연기 합금 도금 강재용 수계 표면 처리제, 이 처리제를 사용한 피복 방법, 및 이 방법을 이용하여 얻어지는 피복 강재의 제공에 관한 것이다. 양이온성 폴리우레탄 수지(A)와, 양이온성 페놀 수지(B)와, 실란 커플링제(C)와, 티타늄의 아세틸아세톤 착체(D)와, 올레핀계 왁스(F)와, 바나듐 화합물(E)과, 아세트산 성분(G)과, 인산 성분(H)을 물에 배합하여 이루어지는 아연 도금 강재용 또는 아연기 합금 도금 강재용 수계 표면 처리제에 관한 것이다. [Problem] To provide: an aqueous surface treatment agent that is for a zinc plated steel material or a zinc-based alloy plated steel material, that has satisfactory properties such as corrosion resistance, post-degreasing corrosion resistance, coating adhesion, post-degreasing coating adhesion, blackening resistance, condensation whitening resistance, treatment agent stability, actual device operability, and the like, and that can form a coating having excellent stack whitening resistance and filament tape resistance; a coating method using the treatment agent; and a coated steel material obtained using the method. [Solution] This aqueous surface treatment agent for a zinc plated steel material or a zinc-based alloy plated steel material is obtained by blending a cationic polyurethane resin (A), a cationic phenolic resin (B), a silane coupling agent (C), an acetylacetone complex of titanium (D), an olefin wax (F), a vanadium compound (E), an acetic acid component (G), a phosphoric acid component (H), and water.
