Abstract
The invention relates to a preparation process of a composite coating on a metal surface. The preparation process of the invention comprises the following flows: surface preparation, application of liquid paint, drying or solidification, electrostatic spraying of powder paint, and baking solidification or leveling. In the preparation process of the composite coating of the metal surface, the liquid paint coating is bottomed, finish coats of the powder paint is used to form the composite coating, and the advantages of the powder paint and the liquid paint are combined to greatly improve the construction efficiency and simultaneously increase the decoration of the coating.
Description
Technical field
The present invention relates to a kind of preparation technology of coating, be specifically related to the preparation technology of a kind of metal surface composite coating.
Background technology
The composite coating application is to strengthen surfacecti proteon at present and improve one of common technology of decorate properties, most composite coating application, for preventing that holiday and ply adhesion from descending, the coating of two kinds of different cultivars is not used with basically in same composite coating system, all carries out the multipass application in same material field or coating process field and forms.And present coating variety is more, their pluses and minuses difference, and complementary phenomenon mostly has superiority.For the subregion that electrostatic screen is arranged, if adopt earlier the powdery paints electrostatic spraying, again through the liquid coating repair technology, but surface color is difficult to reach consistent after solidifying fully, and adopt the liquid coating bottoming, with the composite coating technology of powdery paints cover research, application are not arranged very also.
Summary of the invention
In order to solve some unfavorable problems that existing composite coating exists, the invention provides the preparation technology of a kind of metal surface composite coating, the preparation technology of this metal surface composite coating feels secure with the liquid coating coating, form composite coating with the powdery paints coat finishing, the advantage of consolidated powder coating and liquid coating, improve efficiency of construction greatly, increased the ornamental of coating simultaneously.
Preparation technology's of the present invention flow process is: surface preparation → application liquid coating → drying or curing → electrostatic spraying powder coating → baking-curing or levelling.
Shot Blasting is carried out in the metal surface, remove adjuncts such as surperficial oxide skin, welding slag, iron rust, greasy dirt; Through the brushing liquid coating, treat its surperficial bone dry, curing, described liquid coating is to have the dual-component coating that curing agent participated in and can carry out normal-temperature reaction, and again by electrostatic spraying powder coating, the workpiece of spray coating powder paint enters that heating space is heating and curing, levelling.
The invention has the beneficial effects as follows: the preparation technology of this metal surface composite coating feels secure with the liquid coating coating, form composite coating with the powdery paints coat finishing, the advantage of consolidated powder coating and liquid coating, improve efficiency of construction greatly, the advantage of consolidated powder coating and liquid coating improves efficiency of construction greatly, improves efficiency of construction, economize on resources and the energy, the efficient height, pollute less, Corrosion Protection and decorative surface be fabulous.
Specific embodiment
Impeller blasting is carried out in the metal surface, remove adjuncts such as surperficial oxide skin, welding slag, iron rust, greasy dirt, make the surface of the work ball blast to the Sa2.5 level, easily form the zone of electrostatic screen, brushing liquid coating at workpiece, color is consistent with the color of the powdery paints that is about to spraying, in the air drying completion of cure, behind electrostatic spraying powder coating, enter in 200 ℃ of baking ovens and be baked to 10min, after treating that coating is solidified fully, workpiece is taken out.Through the metal works of this explained hereafter, production efficiency height, solid colour, good decorative property.
Claims (2)
1. the preparation technology of metal surface composite coating is characterized in that: surface preparation → application liquid coating → drying or curing → electrostatic spraying powder coating → baking-curing or levelling.
2. the preparation technology of metal surface according to claim 1 composite coating is characterized in that: Shot Blasting is carried out in the metal surface, remove adjuncts such as surperficial oxide skin, welding slag, iron rust, greasy dirt; Through after the surface treatment, brushing liquid coating, the liquid coating here are to have the dual-component coating that curing agent participated in and can carry out normal-temperature reaction, after treating its surperficial bone dry, solidifying, electrostatic spraying powder coating, the workpiece of spray coating powder paint enter that heating space is heating and curing, levelling.
