Abstract
The purpose of the present invention is to provide a novel sealing treatment liquid for an anodic oxide film of an aluminum alloy, which is characterized by containing a thickening polysaccharide.
Description
Technical Field
The present invention relates to a sealing treatment liquid for an anodic oxide film of an aluminum alloy.
Background
An anodized film of an aluminum alloy is generally subjected to a sealing treatment for preventing contamination, improving corrosion resistance, and the like. As a sealing treatment method, a sealing treatment with boiling water, a sealing treatment with water vapor, a sealing treatment at normal temperature, a sealing treatment with nickel acetate using a nickel acetate aqueous solution, and the like are known.
Among them, the sealing with nickel acetate is particularly used for the reasons that the corrosion resistance of the coating is more easily obtained than the sealing with boiling water, the sealing operation efficiency is more excellent than the sealing with steam, and the liquid management is more easily performed than the sealing at normal temperature. However, since nickel allergy and toxicity of a fine powder nickel salt are problematic, it is necessary to exhibit sealing performance such as corrosion resistance and sealing degree equivalent to those of nickel acetate sealing as a sealing method without using a nickel salt in producing an anodic oxide film.
Patent document 1 is a technique of the present applicant, and is a sealing treatment liquid for an anodic oxide film of an aluminum alloy containing an alkali metal salt, a pH buffer and a surfactant. When the plugging treatment liquid is used, the plugging performance can be imparted to the anodic oxide film of the aluminum alloy to the same extent as when the plugging treatment liquid containing a nickel salt is used, and excellent contamination resistance can be imparted.
Patent document 2 describes a method of sealing an anodized aluminum surface by irradiation with light irradiation energy using an activated inorganic substance, organic substance, or a free and ionized complex. In this technique, only pb (CH) is used3COO)2And NiSO4As a result of the pore sealing treatment agent.
Patent document 3 describes that a hydrophilic film (anodic oxide film) can be formed on an aluminum substrate and subjected to a sealing treatment. In this technique, only an example of using an aqueous sodium silicate solution is described as a sealing treatment using particles.
