The application roller of double-color aluminium-plastics composite plate finishing coat
(1) technical field
The utility model relates to a kind of application roller that has the double-color aluminium-plastics composite plate finishing coat of two kinds of colors at grade.Double-color aluminium-plastics composite plate is mainly used in indoor and outdoor decorations such as sign, display card, market, gas station, facility, chain store and decorates.Belong to decorative materials technology.
(2) background technology
The coating of conventional aluminum plastic clad plate is monochromatic coating, promptly adopt primary coat, in be coated with, face is coated with three layers of full width of cloth coating.Owing to be full width of cloth application, temperature control is convenient, simple to operate when three layers of coating for the tradition aluminium-plastic panel, interlayer can not occur in conjunction with not firm situation, particularly floating coat and the bond strength height of finishing coat.
When the conventional aluminum plastic clad plate needed color combination in the design and construction process, what take usually was to utilize the aluminium-plastic panel splicing of the glued seam method of sealing with two different colours.This method is because of the existence of gluing seam, and it is not attractive in appearance to decorate the rear surface, and installs inconvenient.
For overcoming above-mentioned defective, be badly in need of a kind of double-color aluminium-plastics composite plate that has two kinds of colors at grade.
The application roller that is provided in the market all can only carry out monochromatic application, and promptly the plate face is same color entirely, can not realize double-colored or the multicolor operation.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of application roller that can realize the double-color aluminium-plastics composite plate finishing coat of double-colored or multicolor operation is provided.
The purpose of this utility model is achieved in that a kind of application roller of double-color aluminium-plastics composite plate finishing coat, it is the raw material steel billet that described application roller adopts 45# carbon steel, remove not needing the roll surface position of application, this position depth of section is lower than needs application roll surface height 20~25mm, is coated with the chromium layer on need application roll surface surface.
The utlity model has following characteristics:
The utility model is by change application roller, can realize double-colored or the multicolor operation to reach interlayer combination firm (floating coat and finishing coat), the boundary binding site of the situation of depainting can not occur, peeling off, particularly two kinds of colors.Simultaneously, the knot suture bar of two kinds of colors is straight, not burr, the limit of collapsing.

Chromium layer 2.
(5) specific embodiment
Referring to Fig. 1, the utility model relates to a kind of application roller of double-color aluminium-plastics composite plate finishing coat, it is the raw material steel billet that described application roller is selected 45# carbon steel for use, remove not needing the roll surface position of application, this position depth of section is lower than needs application roll surface height 20~25mm, need carry out chromium plating 2 processing by application roll surface 1 again, control application roller surface accuracy at 2.0~2.5 μ m, 10~15 ° of application roller two edges chamferings.
