Abstract
The invention discloses a high-weatherproof silver powder paint color coated steel plate. The coated steel plate comprises a base layer (1) taking a zinc coated plate or an aluminum-zinc coated plate as a base material, wherein a front treatment layer (2), a primer layer (3) and a silver powder paint layer (4) are sequentially arranged on the facade of the base layer (1) from inside to outside; a front treatment layer (6), a primer layer (7) and a finish paint layer (8) are sequentially arranged on the back surface of the base layer (1) from inside to outside; the primer layer (3) on the facade of the base layer is made of polyurethane primer; the silver powder paint layer (4) is between 18mu m and 22mu m in thickness; a varnish layer (5) is arranged outside the silver powder paint layer (4) and made of transparent varnish; the varnish layer (5) is between 10 mu m and 15mu m in thickness. The color coated steel plate is simple in manufacturing process; the silver powder paint layer is coated with a layer of transparent varnish, so that the anti-corrosion performance and the weatherproof performance of the color coated steel plate are improved while the color brilliance of the color coated steel plate is ensured, i.e.,, the color coated steel plate is richer in color. According to the testing, the time of a salt fog test of the silver powder paint color coated steel plate with the transparent varnish layer can be prolonged by 500 hours or so.
Description
Technical field
The present invention relates to a kind of color coated steel sheet, specifically a kind of aluminium paint color coated steel sheet with high-weatherability energy.
Background technology
Aluminium paint is aluminium paint, refers to that one adds aluminium powder in paint as a kind of special pigment, makes it have special flash effect, the paint of metalloid look.
The flicker degree of silver powder generally with the silver powder particles particle size of selecting, relevant with particle diameter silver powder content ratio, the higher aluminium paint of general visual flicker degree, needs the silver powder particle diameter of 70-80% more than 30 μ m.When requiring degree of flicker higher, need by the aluminium paint coil of strip salt spray test of this type of silver powder particles production poor.
And aluminium has reproducibility, very easily oxidation, in view of the metal properties of above-mentioned aluminium powder, the color coated steel sheet acid-alkali-corrosive-resisting that uses aluminium paint to produce is poor, and weatherability is not good.
For solve aluminium paint produce color coated steel sheet acid-alkali-corrosive-resisting poor, the problem that weatherability is not good, manufacturer generally selects aluminium powder and the stronger resin of parcel property that particle diameter is less, and aluminium powder is wrapped in resin as far as possible, with this, improves its corrosion-resistant, weatherability.
Adopting said method to improve color coated steel sheet corrosion-resistant, that weatherability is produced, is that the stronger resin of parcel property is wrapped in aluminium powder major part in resin due to what use, and the product colour therefore obtaining is darker, and silver powder flicker degree deficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high weather-proof aluminium paint color coated steel sheet, and on this color coated steel sheet, corrosion-resistant, the weather resistance of aluminium paint is greatly enhanced.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of high weather-proof aluminium paint color coated steel sheet, comprise the basic unit take galvanized sheet or aluminium plating zinc plate as base material, in the front of described basic unit, be preprocessing layer, prime coat, silver powder enamelled coating from inside to outside successively, at the back side of described basic unit, be preprocessing layer, prime coat, top coat layer from inside to outside successively, the prime coat material in described basic unit front is polyurethane primer, the thickness of described silver powder enamelled coating is 18～22 μ m, at described silver powder enamelled coating, also has layer of varnish outward.Polyurethane primer can be selected the polyurethane primer of selling outside Nippon Paint (China) Co., Ltd..
Due to varnish poor heat resistance, under the effect of ultraviolet light, easily flavescence, will bring impact to silver powder degree of flicker like this.For this reason, the clear varnish thickness of layer of varnish of the present invention is selected 10～15 μ m, preferably 15 μ m.Under above-mentioned thickness, contribute to the light that is radiated at surface of steel plate to reflect away, at utmost avoid the layer of varnish flavescence of being heated, affect the flicker degree of silver powder.
Preprocessing layer, prime coat and the top coat layer at the basic unit back side adopt prior art, for conventional technological means realizes not doing, change.
In order to improve coating quality and the efficiency of clear varnish, will there be certain roughness on the surface of silver powder enamelled coating.But during surface roughness Ra >1.6 μ m, just can adopt range estimation, during surface roughness Ra >1.6 μ m, can see intuitively in other words.General silver powder enamelled coating is due to reasons such as light, and its surperficial roughness is not very obvious, and when varnish coating layer outside silver powder enamelled coating, it is very obvious that the roughness of silver powder enamelled coating will become, and have a strong impact on the color of product, and silver powder flicker degree.For head it off, silver powder enamelled coating surface roughness Ra of the present invention is controlled at 0.3～1 μ m.The surface roughness that general surperficial enamelled coating reaches optimum protection effect is 55～65 μ m, because silver powder enamelled coating also has layer of varnish outward, therefore silver powder enamelled coating surface roughness Ra is significantly controlled.Silver powder enamelled coating surface roughness Ra is controlled at 0.3～1 μ m, utilizes on the one hand roughness to be convenient to apply, and roughness is too low, can cause adhesive force bad, finds expression in especially thick film enamelled coating; Solve on the other hand color coated steel sheet product appearance problem.
Varnish, has another name called varnish, is to be that main film forming substance is adding the coating of solvent composition by resin, and it is not containing the transparent of pigment or with light flaxen coating, good luster, and film forming is fast, and main component is resin and solvent or resin, oil and solvent.
The technique that the present invention manufactures is simple, by application layer of transparent varnish on silver powder enamelled coating, has improved corrosion-resistant, the weatherability of product, guarantees again its bright-colored degree, and color is abundanter.Through experiment, the aluminium paint color coated steel sheet salt mist experiment that the present invention scribbles clear varnish layer can improve about 500 hours.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, high weather-proof aluminium paint color coated steel sheet comprises the basic unit 1 take galvanized sheet or aluminium plating zinc plate as base material, in the front of described basic unit 1, is preprocessing layer 2, prime coat 3, silver powder enamelled coating 4 and layer of varnish 5 from inside to outside successively; At the back side of described basic unit 1, be preprocessing layer 6, prime coat 7, top coat layer 8 from inside to outside successively.
The aluminium paint of aluminium powder enamelled coating 4 is again antirust paint or aluminium paint, as the aluminium paint of selling outside the ippon coating Co., Ltd of Shanghai.Conventional aluminium paint has two kinds at present, a kind of common ready-mixed aluminum paint (majority is phenolic aldehyde character), for general anti-rust metal surface, one is strong anticorrosion anti-Acidity of Aikalinity aluminium paint, for marine metal surface, and the very strong metal surface, chemical plant of Acidity of Aikalinity.Aluminium paint of the present invention can be selected from above-mentioned two kinds, specifically according to practical application, selects.
