Embodiment Construction

[0010] Attached below figure 1 ~ attached figure 2 , taking the rolling printing of three-dimensional wood grains on the aluminum profiles for construction as a specific illustration, and the specific implementation measures are as follows:

[0011] One, the technological process of this embodiment is briefly described as follows:

[0012] Metal workpieces to be treated (pre-treated)—spraying primer—primary pre-curing—spraying rendering color base powder—full brushing and leveling rendering color base powder—secondary preparatory curing—spraying cover powder—rolling Embossed texture - final curing - quality inspection - packaging

[0013] Two, the main technological process described in above-mentioned (1):

[0014] 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 t...

Abstract

The present invention is text and graph roller printing process and apparatus for metal powder painting part. The process includes the pre-treatment of the metal painting part, spraying the first layer of base color powder paint, curing at 155-175 deg.c for 5-8 min, spraying the second layer of powder paint, re-curing at 155-175 deg.c for 5-8 min, spraying the third facing powder paint to form the destination color, printing with rubber roller with wood grains or other patterns to form the required pattern, and final curing at 190-210 deg.c for 10-15 min to obtain stereo grains with gradually changed colors. The stereo grains formed in the technological process of the present invention has the features of strong touch and visual stereo feeling and long maintained period.

Description

Technical field: [0001] The invention relates to a rolling printing process and main equipment for imitating hand-feeling wood grain, pattern and other texture graphics of metal powder sprayed parts. Background technique: [0002] At present, the powder-coated aluminum profiles for construction, the large-scale aluminum and steel metal decorations for daily and industrial use, due to the complexity of the powder coating formula, cannot easily obtain the three-dimensional appearance of the image. Wait for texture effects! There is a transfer printing process that 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 the outer surface. 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...
