According to the method for processing the surface of the steel plate, the paper, with decorative patterns, such as grainy paper directly adheres to the steel plate through the specially-made glue, so that the steel plate processed through the method is free of rusting and corrosion, adhesion of the grainy paper to the steel plate is firm, the whole process is easy to operate, pollutant discharge caused by high-temperature transfer print is reduced, the energy consumption of the whole processing technology is reduced, the labor cost is greatly reduced, and the production efficiency is improved.

Description

A kind of surface of steel plate processing method
Technical field
The present invention relates to a kind of surface treatment method, be specifically related to a kind of surface treatment method that pattern is set at surface of steel plate.
Background technology
Steel plate is solid be firmly widely used, but it is easily by dioxygen oxidation moistening in air, therefore need the surface of steel plate to process before it uses, to avoid steel plate oxidized, increases its service life.And, in order to reach attractive in appearance or wooden simulated effect, conventionally on the surface of steel plate, understand various patterns in transfer printing, as the common steel timber with grain pattern.
And in prior art, in the method for surface of steel plate pattern transferring, normally by after steel plate acid-washing phosphatization, its plastic-blasting is dried, then pattern is arrived to surface of steel plate by high temperature transfer, then transfer paper is removed and sprayed transparent paint again and obtain.If the patent No. is three processes of printing, thermal dye sublimation transfer printing processing procedure that stainless steel stereo shaping plate picture on surface heat-transferring method comprises pattern on surface preparation, thermal dye sublimation transfer printing paper as described in ZL200510062378.5 " corrosion resistant plate surface treatment, pattern heat transfer process and the plate making thereof ".And thermal dye sublimation transfer printing processing procedure comprises four step: A, will cover the treated surface that is fixed on stereo shaping steel plate with the figuratum one side of figuratum thermal dye sublimation transfer printing paper; B, with vacuum suction hold down gag, the transfer paper and the stereo shaping steel plate that overlay on stereo shaping surface of steel plate are fitted tightly; C, by above-mentioned, fit tightly stereo shaping steel plate under state and transfer paper baking, make pattern thermal dye sublimation transfer printing on transfer paper to stereo shaping surface of steel plate; D, peel off transfer paper.
This by being transferred in surface of steel plate, that the method step of pattern is set is loaded down with trivial details, and needs can produce a large amount of waste gas in heating, production process, and also higher to operating personnel's specification requirement.
Summary of the invention
The object of the present invention is to provide a kind of high temperature transfer, the surface of steel plate processing method that simple to operate, process costs is low of not needing.
For achieving the above object, the technical solution used in the present invention is: a kind of surface of steel plate processing method comprises step:
A. steel plate acid-washing, phosphatization are processed;
B. the surface of steel plate after processing is pasted decorative paper layer with bonding glue;
C. at decorative paper layer outer surface, spray paint and obtain product.
It is the processing means of commonly using that pickling, phosphatization are processed, and pickling is with solution such as hydrochloric acid or sulfuric acid, the oxide layer of surface of steel plate, dust, Ester to be washed; And phosphatization is to allow steel plate immerse in Phosphating Solution, at surface of steel plate, produce the water-fast phosphating coat of one deck, prevent that to a certain extent steel plate is corroded, also can improve the adhesive force of surface of steel plate.Steel plate is just directly coated with last layer bonded adhesives water after pickling and phosphatization processing on surface, then decorative paper layer is attached to surface, finally sprays one deck paint vehicle again.Decorative paper layer can be woodgrained paper, can be also other facing paper, is mainly the facing paper that Decoration Industry is conventional.
Further, described bonding glue comprises following parts by weight of component: 1000-1500 part water, 80-100 part polyvinyl alcohol, 0.2-1 part ammonium persulfate, 100-150 part vinyl acetate, 0.2-1 part emulsifying agent, 0.2-1 part NaOH, 2-5 part vinyl acetate-ethylene copolymer, 1-5 part matal deactivator.
Emulsifying agent is a kind of surfactant, when it is dispersed in dispersate surperficial, form film or electric double layer, can make decentralized photo with electric charge, so just can stop the droplet of decentralized photo to condense mutually, make the emulsion of formation more stable, as polyacrylamide amine emulsifier, non-ionic surface active agent etc.Vinyl acetate-ethylene copolymer is ethylene-vinyl acetate copolymer, claims again EVA, VAE, EVA resin.Matal deactivator is the additive that suppresses the various impacts of metal pair oil, as compound, the N of three (O, O-diη-propyl two sulfo-s) this class antimony of phosphate antimonic salt, N'-bis-salicylidene propane diamine etc.
Further preferred, described bonding glue comprises following parts by weight of component: 1100-1300 part water, 85-95 part polyvinyl alcohol, 0.2-0.6 part ammonium persulfate, 130-150 part vinyl acetate, 0.2-0.5 part emulsifying agent, 0.3-0.6 part NaOH, 3-5 part vinyl acetate-ethylene copolymer, 1-2 part matal deactivator.
Further preferred, described bonding glue comprises following parts by weight of component: 1200 parts of water, 90 parts of polyvinyl alcohol, 0.5 part of ammonium persulfate, 140 parts of vinyl acetates, 0.4 part of emulsifying agent, 0.5 part of NaOH, 4 parts of vinyl acetate-ethylene copolymers, 1.5 parts of matal deactivators.
Further, with inorganic base or inorganic acid, to be modulated into final pH be 7 ± 0.1 to described bonding glue.That is to say that it is 7 ± 0.1 that bonding glue is finally modulated into pH with inorganic acids such as the inorganic bases such as NaOH or potassium hydroxide or hydrochloric acid sulfuric acid.
Further, described emulsifying agent is nonionic emulsifier.Nonionic emulsifier is in the aqueous solution, can dissolve and not produce the surfactant of ionization, mainly contain ether class, ester group kitchen range, acyl by class and heterocyclic etc., as conventional NPE, OPEO, tribenzyl phenol polyethenoxy ether, phenethyl phenol polyethenoxy ether, ethoxylated dodecyl alcohol, polyoxyethylene oleic acid ester, polyol fatty acid ester, alkylbenzenesulfonate etc.
Further preferred, described matal deactivator is N, N'-bis-salicylidene propane diamine.
Further preferred, described bonding glue sprays to surface of steel plate by high pressure airless spray equipment.Namely with booster pump, coating is increased to high pressure, by very thin spray orifice, spray, make coating form the fan-shaped vaporific surface of steel plate that is coated to.This spraying method is convenient, and coating thickness is more even.
In technique scheme, the consumption of each component is the optimum feed stock ratio that participates in reaction, but the variation that those skilled in the art can instruction according to the present invention be equal to.For example: because the parameter that the error of industrial production itself causes changes with technical scheme of the present invention, be equal to.
The paper that the present invention directly has woodgrained paper etc. decorative pattern by the glue with special is adhered on steel plate, and corrosion phenomena can not occur the steel plate after processing by this method, and the bonding of woodgrained paper and steel plate is very firm.And whole process operation is simple, reduced the discharge of the high temperature transfer produced pollution, reduced the energy consumption of whole treatment process, greatly reduced cost of labor, improved production efficiency.
