Problems solved by technology

However, this method makes the metal parts sprayed with ink flat printing graphics, which lacks permeability in the coating and is easy to fade, and the retention is not long.
Moreover, the graphics and texts are flat graphics and texts, and the color layering of the graphics surface is less, which limits the visual perception of sprayed parts as decorations.

Embodiment Construction

[0008] Take the speckled and three-dimensional crystal coating sprayed on the aluminum profiles for construction as a specific illustration, and the specific implementation measures are as follows:

[0009] One, the technological process of this embodiment is briefly described as follows:

[0010] The metal workpiece to be treated (pre-treatment) - spraying primer - one pre-curing - spraying another layer of paint - final curing - quality inspection - packaging

[0011] Two, the main technological process described in above-mentioned (1):

[0012] The surface of the metal workpiece will have defects such as unevenness or scratch marks, and the appearance of the workpiece or the appearance color after pretreatment is prone to uneven phenomena, so it is necessary to spray the base color powder coating on the workpiece to eliminate the above. Base color powder coatings mainly use thermosetting powder coatings, such as: pure polyester, epoxy, polyurethane, etc. The thickness of ...

Abstract

A spray technology for generating a multi-color spot-state stereoscopic crystalline pattern on the surface of a metal workpiece includes such steps as pre-treating of said metal workpiece, spraying a priming color paint layer, pre-solidifying, electro-statically spraying the powder paint with another color in pulse mode, and solidifying. It is possible to electro-statically spray the paints with different colors several times.

Description

Technical field: [0001] The invention relates to a spraying process for obtaining a multicolored spot-like three-dimensional crystal layer on a metal sprayed piece Background technique: [0002] At present, due to the complexity of powder coating formulations, it is not easy to obtain colorful three-dimensional crystal dot patterns for aluminum profiles for construction, daily and industrial large-scale aluminum, steel and other metal decorations that have been powder-coated! The existing transfer printing technology allows the metal powder sprayed parts to pass through the secondary thermal transfer technology after spraying, so that the metal parts can be sprayed with plane texture graphics on their outer surfaces. But what this method makes the metal part spraying part obtain is ink planar printing picture and text, and it lacks permeability in coating and fades easily, and retention is not long. Moreover, the graphics and text are planar graphics and texts, and the colo...
