Problems solved by technology

However, limited by the physical and chemical properties of aluminum itself, on the one hand, its surface hardness is low, and it is prone to scratches or scratches; on the other hand, the color of the panels and profiles produced can remain bright for a period degree, but after a period of time (usually about one-third of its equipment life), its color will become lighter or even completely faded, especially in an environment with strong light intensity and long light time, it can keep bright degree time will be shorter
In the 1990s, a stainless-steel-like aluminum profile appeared on the market. It used electrophoresis to form a layer of stainless steel-like metal color film on the surface of the aluminum profile. Although its surface hardness is higher than that of conventional aluminum profiles Slightly higher, but the time it can maintain (including hardness and color) is not too long, so its durability is poor

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. The following description is by way of example, but the protection scope of the present invention should not be limited thereto.

[0018] The imitation stainless steel aluminum material surface treatment process of the present embodiment, its specific technological process is as follows:

[0019] 1. Initial surface treatment:

[0020] A. Degreasing:

[0021] Using the conventional acid degreasing method, the normal temperature degreasing agent is composed of surface active medium, oxidizing agent, complex compound and inorganic acid compound compound alkali, and then adding dilute sulfuric acid to prepare the degreasing liquid.

[0022] When degreasing, put the aluminum parts in the degreasing liquid (the temperature is controlled at 45±2°C, and the time is 180S±30S), which can quickly remove the oil stains and grease marks on the surface of the treated...

Abstract

The invention discloses an imitated stainless steel aluminum surface treatment technology, relating to the technical field of aluminum surface treatment. The technological flow comprises the following steps of: (1) surface pretreatment: A, oil removal; B, dirt removal; C, anode oxidation; D, coloring; and E, primary hole sealing; (2) surface re-treatment: F, spraying of a mixed coating; and G, curing. The surface of the aluminum product after the treatment has relatively high hardness and strength as well as the characteristics of bright color, long maintaining time and the like; and the technology is suitable for treating panels and sections made from aluminum products and having various colors.

Description

technical field [0001] The invention relates to the technical field of aluminum material surface treatment, in particular to a surface treatment process for imitating stainless steel aluminum material. Background technique [0002] In the prior art, due to its light weight, low cost, easy processing and molding, and easy coloring and dyeing, aluminum can be processed into various colors. Therefore, it has been widely used. panels and profiles. However, limited by the physical and chemical properties of aluminum itself, on the one hand, its surface hardness is low, and it is prone to scratches or scratches; on the other hand, the color of the panels and profiles produced can remain bright for a period degree, but after a period of time (usually about one-third of its equipment life), its color will become lighter or even completely faded, especially in an environment with strong light intensity and long light time, it can keep bright The degree time will be shorter. In the...
