Abstract
The present invention relates to a method for making coloured coating stainless steel, which comprises the step (1): the surface of stainless steel is first processed, and the surface of the stainless steel forms a tiny hole pitting surface; the step (2): one to three coloured coatings with strong binding force are coated and plated on the tiny hole pitting surface of the stainless steel through surface processing, and the thickness of the coloured coatings is about 5 to 160 mu m; the step (3): the coloured coatings are solidified; the step (4): one to two glazing transparent coatings are coated on the coloured coatings, the thickness of the glazing transparent coatings is about 5 to 45 mu m, and then, the glazing transparent coatings are solidified; the step (5): finally, one to two protective glue films for packaging and transportation are covered at the surfaces of the glazing transparent coatings. Not only can colors be abundant, but also a base material of stainless steel can be protected. The appearance decorative effect, and the performance of corrosion resistance, abrasion resistance, and the like of the stainless steel are greatly enhanced. Coloured coating stainless steel can be applied to decorative board materials, pipe materials, sectional materials, articles of daily use, small workpieces, construction decorations and construction door and window products.
Description
Technical field
The present invention relates to the stainless making method of a kind of coloured coating.
Background technology
The existing stainless making method of coloured coating is directly to spray coloured coating on stainless steel surface, and its coloured coating and stainless steel base are bonding not firm, are easy to come off.The coloured coating stainless steel also has a shortcoming the most fatal: antifouling property is very poor, is easy to be made dirty, therefore, has limited its development greatly.For improving the stainless antifouling property of coloured coating and satisfy the new demand in market, stainless material is carried out kinds of surface handle deep processing, make it have better properties and better decorative effect is very necessary.
Summary of the invention
The purpose of this invention is to provide the stainless making method of a kind of coloured coating, improve the decorative effect, anti-soil of Color Stainless Steel, anti-aging, wear resisting property and coated adhesive performance, to satisfy the needs of the needs in market, particularly decorated articles and building doors and windows.
The present invention adopts such technical scheme to solve the problems referred to above: the stainless making method of coloured coating has following steps:
Step (1): stainless steel is carried out surface treatment earlier, make its surface form the micropore pitted skin;
Step (2): one to three layer of coloured coating of coating on above-mentioned surface treated stainless steel micropore pitted skin, the thickness of this coloured coating is 5 microns to 160 microns;
Step (3): above-mentioned coloured coating is cured;
Step (4): be coated with on above-mentioned coloured coating and load onto one to two layer of Lacquer finish Clear coating, the thickness of this Lacquer finish Clear coating is about 5 microns to 45 microns, then to its curing;
Step (5): last again at one to two layer of protection glued membrane that is used for packed and transported of surface coverage of this Lacquer finish Clear coating.
Above-mentioned steps (1) has three kinds of selectable methods:
Method 1. sandblast forms stainless steel micropore pitted skin;
Method is 2. at CrO
3And H
2SO
4Chemical stain solution in form stainless steel micropore pitted skin by oxidation;
Method is the method for comprehensive above-mentioned two kinds of methods 3..
The coloured coating of above-mentioned steps (2) is powder coating, liquid coating or fluorocarbon coating.
The coating process of the coloured coating of above-mentioned steps (2) have three kinds selective: 1. adopt spray of direct liquid coating or spread coating; 2. adopt direct powder coating spraying method, 3. adopt electrophoretic paint electrophoretic painting method.
It is photocuring or thermofixation that coloured coating in the above-mentioned steps (3) solidifies.
Above-mentioned steps (4) can be omitted and remove.
Beneficial effect: the stainless making method of coloured coating of the present invention is compared with existing method and is had the following advantages:
A, make the coloured coating stainless steel have colored application layer, the color of coating, be not interference of light look, it can not resemble the oxide film interference of light look of the painted generation of stainless steel direct oxidation and cause the color layer change in color because of the subtle change of the thicknesses of layers that dirt (as: clc layer) causes.
B, make the stainless colour of coloured coating very abundant, can be according to any furnishing distinct colors of user's needs;
C, coloured coating stainless steel are to cover one deck coloured coating again at stainless steel surface, and this not only makes its color very abundant, and has protected stainless steel substrate.Therefore it has also not only improved stainless exterior decorative effect greatly but also has improved performances such as stainless solidity to corrosion, wear resistance.
D, coloured coating stainless steel breed structure is greatly enriched, applicable to dalle, stainless steel pipe, section bar, daily necessities, small workpiece and other finished product, this popularization to Color Stainless Steel particularly will have very big realistic meaning in the popularization of decoration, building doors and windows Color Stainless Steel goods.
