chapas de aço galvanizadas e agente de tratamento de superfície para as mesmas. a presente invenção diz respeito a um agente de tratamento de superfície para chapas de aço galvanizadas, que compreende derivados de silano contendo epóxi, derivados de silano contendo alquila, derivados de alcóxi silano, e um ou mais selecionados do grupo que consiste em uma dispersão aquosa de polímero catiônico, uma dispersão de polímero não-iônico e um polímero solúvel em água. é também descrito um método para sua produção, que compreende misturar cada componente, uniformemente, por 0,5 a 8 horas, a 5 a 70oc. são ainda proporcionadas chapas de aço galvanizadas revestidas com o agente de tratamento de superfície sobre a superfície e um método para sua produção. o agente de tratamento de superfície para chapas de aço galvanizadas tem resistência à corrosão, resistência alcalina, resistência a solvente, propriedade de revestimento, resistência à temperatura alta e condutividade elétrica, excelentes. Disclosed is a surface treatment agent for galvanized steel sheets, which comprises epoxy-containing silane derivates, alkyl-containing silane derivates, alkoxy silane derivates and one or more selected from the group consisting of a cationic polymer aqueous dispersion, a non-ionic polymer aqueous dispersion and a water-soluble polymer. Also disclosed is a method for producing it, which comprises mixing each component uniformly for 0.5 to 8 hours at 5 to 70°C. Further provided are galvanized steel sheets coated with the surface treatment agent on the surface and a production method thereof. The surface treatment agent for galvanized steel sheets has excellent corrosion resistance, alkali resistance, solvent resistance, recoating property, high temperature resistance and electrical conductivity.
