Abstract
The present invention discloses an imitation gold electrolytic coloring agent for aluminium and aluminium alloy products. The present invention is made of the following components according to the total weight percentage: 0.15 to 2.5% of benzene sulfonic acid, 0.2 to 10% of sulfuric acid, 0.5 to 10% of potassium hypermanganate, 0.3 to 2.5% of magnesium sulphate, 0.01 to 0.1% of orthoboric acid, 0.2 to 15% of catechol, 0.01 to 0.05% of ascorbic acid, and deionized water or tap water for the rest of the mixture. The imitation gold electrolytic coloring agent for aluminium and aluminium alloy products can be used in the technological method of plating imitation gold films on the surfaces of aluminium and aluminium alloy products. The technological method comprises: the preprocessing process step of removing oil on the surfaces of the products and etching the surfaces of the products by alkali for polishing, the process step of sulfur acid anodic oxidation so as to form the films, the process step of electrolytic coloring and the process step of closing. The present invention has the advantages that the oxidation films formed by the sulfuric acid anodic oxidation have the advantages of corrosion resistance, wear resistance and light resistance; the electrolytic solution by using the formula is stable, and the electrolytic conditions are easy to control; the electrolytic coloring can be evenly carried out on the oxidation films; the plated products have vivid imitation gold decoration effect; since the component materials of the electrolytic coloring agent have the advantages of low price and easy control of technology, the present invention has the advantage of low production cost and widens the application range.
Description
Technical field
The present invention relates to the surface treatment and the decoration technique of aluminium and Al-alloy products, exactly relate to the imitative golden electrolytic coloring agent of sulphuric acid oxidation coating of a kind of aluminium and Al-alloy products.
Background technology
In aluminium and Al-alloy products manufacturing enterprise, aluminium and aluminum alloy surface are handled, protected and decorates, comparatively sophisticated technology has been arranged.At present to painted staining and the electrolytic process of mainly containing of product surface, goods of handling with staining wherein, because colorant solution instability, the difficult control of its pH value when painted, make product criticize and batch between form obvious aberration, thereby cause product colour repeatability very poor, make difficult quality guarantee, and the solidity to corrosion of product surface film, wear resistance and photostabilization are also poor; Electrolytic process generally can make the coloring film of aluminium and aluminum alloy product surface that solidity to corrosion, wear resistance and photostabilization are preferably arranged, and tone control is also easy than staining.But, up at present painted to the decoration of aluminium and aluminium alloy, only make the titanium look and failed to make the gold look that is gold texture, as adornment is a very big shortcoming, and owing to present titanium look obtains by the electrolysis of selenium salt, raw materials used tin anhydride costs an arm and a leg, and causes production cost high, makes to use to be restricted.
Summary of the invention
The objective of the invention is to: provide a kind of and can obtain the good imitative golden electrolytic coloring agent of gold color and luster effect, solidity to corrosion, wear resistance and photostabilization aluminium and aluminum alloy product surface.
The objective of the invention is to realize by implementing following technical proposals:
The imitative golden electrolytic coloring agent composition of a kind of aluminium and Al-alloy products is characterized in that: by total weight percent, include:
