Problems solved by technology

[0002] At present, most of the surface treatment methods for imitating marble effects on metal workpieces on the market are to print imitation marble patterns on transfer paper first, and then print them on metal workpieces through transfer printing, or directly use imitation marble patterns. The patterned PVC plastic film adheres to the metal workpiece. The metal workpiece painted by these processes not only has a poor imitation of marble effect, but also can only be coated with a marble-like effect on regular metal workpieces, which cannot be repaired and reworked. The adhesion of the imitation marble pattern poor

Embodiment 1

[0016] A construction method for imitating marble effect on metal parts with metal baking paint, comprising the following steps:

[0017] (1) Bottom material treatment: the metal parts are iron parts. First, the iron parts are polished or derusted with a wire brush, then cleaned and degreased with an organic solvent, then pickled, phosphated with phosphating solution, washed with water, and dried; After washing with water, spray with dilute chromic acid and then dry;

[0018] (2) Solid color baking paint spraying: According to the color depth of the desired marble effect, dilute the adjusted solid color (base color) paint to 9 seconds, use a hand-held electrostatic gun or DISK coating machine to spray the diluted paint on the material or dilute it to 11-14 seconds with matte transparent baking varnish, spray the diluted paint on the material manually with a pneumatic spray gun, let it dry at room temperature for 3 minutes, then put it in a 150°C oven and bake for 20 minutes, a...

Embodiment 2

[0023] A construction method for imitating marble effect on metal parts with metal baking paint, comprising the following steps:

[0024] (1) Bottom material treatment: the metal parts are non-ferrous metal products, the non-ferrous metal products are first cleaned with corrosion-inhibiting lye, then treated with nitric acid, then washed with water and dried;

[0025] (2) Solid color baking paint spraying: According to the color depth of the desired marble effect, dilute the adjusted solid color (base color) paint to 10 seconds, and use a hand-held electrostatic gun or DISK coating machine to spray the diluted paint on the material or dilute it to 14 seconds with a matte transparent baking varnish, spray the diluted paint on the material manually with a pneumatic spray gun, let it dry for 5 minutes at room temperature, then put it in an oven at 150°C for 20 minutes, and cool for 30 minutes after baking minute;

[0026] (3) Effect paint spraying: Use a slow-drying thinner to d...

Embodiment 3

[0030] A construction method for imitating marble effect on metal parts with metal baking paint, comprising the following steps:

[0031] (1) Bottom material treatment: the metal parts are non-ferrous metal products, the non-ferrous metal products are first cleaned with corrosion inhibiting lye, then etched with chromic anhydride sulfuric acid solution, then washed with water and dried;

[0032] (2) Solid color baking paint spraying: According to the color depth of the desired marble effect, dilute the adjusted solid color (base color) paint to 10 seconds, and use a hand-held electrostatic gun or DISK coating machine to spray the diluted paint on the material or dilute it to 14 seconds with a matte transparent baking varnish, spray the diluted paint on the material manually with a pneumatic spray gun, let it dry for 5 minutes at room temperature, then put it in an oven at 150°C for 20 minutes, and cool for 30 minutes after baking minute;

[0033] (3) Effect paint spraying: Us...

Abstract

The invention provides a coating method using metal baking paint to achieve imitation marble effect on metal parts, which comprises the following steps of (1) base material treatment, (2) solid color baking finish spray coating, (3) effect paint spray coating, (4) imitation marble effect achievement, and (5) highlight transparent baking finish. The method enables biofidelity of wood grain simulation effect on metal work pieces to be high by design of metal baking paint and the coating method. The effect of wood grain is clear, adhesion is good, and the effect of wood grain can be arranged on irregular work pieces. The coating method is widely applied to metal furniture, metal accessories of the metal furniture, indoor and outdoor ornaments made of metal materials and decoration materials made of metal materials and the like, low in cost and simple in operation.

Description

technical field [0001] The invention relates to the technical field of construction methods of metal baking varnish, in particular to a coating method of using metal baking varnish on metal parts to imitate marble effect. Background technique [0002] At present, most of the surface treatment methods for imitating marble effects on metal workpieces on the market are to print imitation marble patterns on transfer paper first, and then print them on metal workpieces through transfer printing, or directly use imitation marble patterns. The patterned PVC plastic film adheres to the metal workpiece. The metal workpiece painted by these processes not only has a poor imitation of marble effect, but also can only be painted with a marble-like effect on regular metal workpieces, which cannot be repaired and reworked. The adhesion of the imitation marble pattern poor. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provi...
