Embodiment 1

[0026] Taking aluminum sheet as an example, the process of imitating copper wire drawing on the surface of aluminum includes the following steps:

[0027] 1) Conventional chemical pretreatment of aluminum materials, including: a) degreasing, b) chemical polishing, c) neutralization, d) cleaning, e) drying; it is a mature technology in this industry and will not be described in detail here.

[0028] 2) Electrostatic spraying of transparent red outdoor powder coatings containing pigments, wherein:

[0029] a) The equipment adopts a high-voltage electrostatic gun, the static voltage is 50-80Kv, the air supply pressure is 0.6-0.8MPa; the powder suction pressure is 0.05-0.1MPa, the powder fluidization pressure is 0.1-0.2MPa; the air pressure of the powder floating air valve is 0.05-0.1 Mpa; the distance between the powder spray gun and the workpiece is 100-200mm; the upper and lower limit positions are 40-100mm longer than the workpiece;

[0030] b) Bake and cure at 195°C-205°C fo...

Embodiment 2

[0036] Except step 2) electrostatic spraying pure transparent outdoor powder coating, all steps are all identical with embodiment one.

[0037] In this embodiment, an aluminum material with the effect of imitating red copper wire drawing on the surface can also be obtained.

Embodiment 3

[0039] Except step 3) pasting imitation copper base color dark gray blue straight pattern transfer paper, the imitation copper color of its base color is purple red; Coating, also can be pure transparent outdoor powder coating by electrostatic spraying as embodiment two.

[0040] In this embodiment, an aluminum material with the effect of imitating copper wire drawing on the surface can be obtained.

Abstract

The invention relates to a metal material surface coating process, in particular to a metal material surface copper imitation wire drawing process. The technical problem to be solved by the invention is to overcome the defects of the prior art and provide the metal material surface copper imitation wire drawing process with good copper imitation effect, strong copper metal texture, long light-keeping and color-keeping time and easy scale production. The technical proposal is as follows: the copper imitation wire drawing process comprises the following steps of: 1) carrying out conventional chemical pretreatment on the surface of a metal material and leading the metal surface to be clean, smooth and flat; 2) electrostatic spraying a transparent red outdoor powder coating or a pure transparent outdoor powder coating containing pigments; and 3) using a thermal-sensitive transfer paper with copper imitation bottom color of deep sky blue or black straight stripes for carrying out thermal transfer and obtaining the copper imitation wire drawing effect, wherein the straight-silkiness stripes with the color phase of deep sky blue or black silkiness straight textures are printed on the thermal-sensitive transfer paper with the copper imitation bottom color of deep sky blue or black straight stripes, the bottom color of the copper imitation color is light red purple or red purple or light yellow. In addition to the advantages, the copper imitation wire drawing process is more conductive to environmental protection.

Description

technical field [0001] The present invention relates to a coating process on the surface of metal materials, in particular to a copper imitation wire drawing process on the surface of aluminum or stainless steel; the aluminum or stainless steel involved in the present invention is mainly used for building materials and furniture, for example, for making houses Doors and windows and shop windows as well as display cabinets, tea tables and other furniture. Background technique [0002] Aluminum alloy materials are widely used in various fields of people's lives because of their light weight and low price; especially in building materials, and in building materials, they are more used to make the frames of house doors and windows, shop windows and display cabinets. However, because the surface of aluminum is relatively soft and its mechanical properties are poor, it is more for the needs of decoration, and the surface treatment process for it emerges in an endless stream, const...
