Abstract
The invention discloses a powder coating electrostatic spraying color process method for stainless steel, which includes the steps: A, selecting stainless steel and processing the stainless steel into a formed stainless steel part; B, grinding the surface of the formed stainless steel part to lead the surface of the stainless steel part to be neat and smooth; C, polishing the grinded stainless steel part; D, waxing the surface of the surface of the polished stainless steel part; E, phosphatizing the stainless steel part, soaking and cleaning the stainless steel part with purified water, and drying the stainless steel part; F, performing thermosetting powder coating electrostatic spraying for the surface of the stainless steel part in a spray booth; and G, solidifying baking finish for the sprayed stainless steel part in a baking booth at the temperature ranging from 180 DEG C to 200 DEG C for 20 minutes, and obtaining a colored finished stainless steel product after solidifying. The finished product manufactured by the process method is higher in corrosion resistance, less in environmental pollution, high in impact strength and fine in ultraviolet resistance, and the adhesive force of a coating layer is improved.
Description
Technical field
The present invention relates to the stainless steel surfaces Electrostatic Spraying, specifically is the colored process of a kind of stainless powdery paints electrostatic spraying.
Background technology
In the stainless use of primary colors, it is found that stainless appearance color is single, under the irradiation of daylight; Light is dazzling especially, its color and some use occasion and not too harmony of environment, as in public places, the balcony guardrail of residential quarters, protect indoor and outdoor such as window and decorate when using; Some place requires to use of light color or stainless steel that color is soft or the like; For satisfying these requirements, inlay one deck ornament materials at stainless steel surfaces when constructing sometimes, so not only increased cost; And can influence stainless original performance; In addition, stainless corrosion resistance and weatherability are also waited to improve, and the main method that adopts of stainless steel surfaces coloured silkization has spray paint liquid and plastic-blasting method at present; All there is certain shortcoming in these two methods, drop down and cause on the hole or the hole primer thickness is inhomogeneous and adhesive ability is low thereby liquid coating is prone in enough holes underflow; Plastic-blasting method also causes on the hole or hole primer thickness inhomogeneous easily.
The powdery paints electrostatic spraying is a kind of new technology, the new technology of anti-corrosion of metal, decorative coating; It is the spraying coating process that substitutes liquid coating; Owing to be solvent-free spraying; Because thoroughly removed environmental pollution phenomenon, the coating adhesion of electrostatic spraying, corrosion resistance, impact strength, anti-uv-ray are far longer than liquid coating in addition, and the cost effectiveness of electrostatic spraying and liquid spray and Integrated Energy economic indicator also are extremely superior.
Summary of the invention
The objective of the invention is the colored process of stainless powdery paints electrostatic spraying that a kind of corrosion resistance is strong, impact strength good, anti-uv-ray is good.
The technical scheme that realizes the object of the invention provides the colored process of a kind of stainless powdery paints electrostatic spraying, and method step is following:
Steps A: select stainless steel, be processed into the moulding stainless steel part;
Step B: polishing in the stainless steel part surface to moulding, makes stainless steel part surfacing, smooth;
Step C: the stainless steel part to after the polishing carries out polishing;
Step D: the waxing of the surface of the stainless steel part after the polishing is handled;
Step e: carry out phosphatization and handle, use pure water soaking and washing and dry then;
Step F: in the spray room, the thermosetting powder coating electrostatic spraying is carried out on the stainless steel part surface;
Step G: in temperature is 180 ℃～200 ℃ barn, the stainless steel part after the spraying is carried out the baking vanish curing molding and handle, be 20 minutes hardening time, after curing, obtains the colored stainless steel finished product.
Further, in step F, said thermosetting powder coating is a metal powder coating, and coating is crackle coating, the hang down bronze-colored coating of line, golden flower coating, blue and white coating or sesame honeysuckle flower coating, and the bisque coating thickness needs greater than 130um.Or said thermosetting powder coating is metal powder coating, and coating is light coating, low luster coating or frosted coating, and the bisque coating thickness needs greater than 80um.
Further, in steps A, said stainless steel is a bar section of stainless steel, handles through high-frequency welding, accomplishes the moulding stainless steel part.
Or said stainless steel is stainless steel belt sheet material, and said stainless steel belt sheet material detects processings, fine finishining processing, surface finish and saponification processing, degreasing also twice usefulness pure water soaking and washing, dried completion moulding stainless steel part through high-frequency welding processings, eddy current inspection processing, rectification and hydraulic pressure successively.
The present invention has positive effect: adopt the thermosetting powder coating Electrostatic Spray Technology, compare traditional technology, the colored stainless steel corrosion resistance that this method is processed is stronger, and production cost is lower; And can not cause the stainless steel part coating layer thickness inhomogeneous,, thereby can effectively reduce environmental pollution phenomenon, and adhesive force that can enhancement coating, improve the impact strength and the anti-uv-ray of finished product simultaneously owing to do not need the solvent spraying.
