Title:

AUTOMOBILE FUEL CONTAINER MATERIAL EXCELLENT IN ENVIRONMENT COMPATIBILITY AND AUTOMOBILE FUEL CONTAINER

Document Type and Number:

WIPO Patent Application WO/2001/086020

Kind Code:

A1

Abstract:

An automobile fuel container material and an automobile fuel container, being favorable in processability, in corrosion resistance on the inner and outer surfaces, and in weldability, and excellent in environmental compatibility without elution of harmful components such as lead and chromium (VI), and being capable of mass-production at low costs. The automobile fuel container material comprises, formed on at least one surface of a steel sheet, a zinc-plated layer having a deposition amount of 5-80 g/m?2¿ as a first layer, a Ni-plated layer overlying the first layer and having a deposition amount of up to 10 g/m?2¿ as a second layer, and a post-treating layer overlying the second layer and having a deposition amount of up to 5 g/m?2¿ as a third layer, wherein the post-treating layer is formed by painting using as essential components partially reduced chromic acid and reducing organic compounds, or by an electrolytic chromate coating on the lower layer and resin on the upper layer.
