Abstract
The utility model relates to stainless steel, particularly relates to the cated composite coating corrosion resistant plate of tool.It comprises stainless steel substrate, also comprise one deck aluminium sheet, described stainless steel substrate is provided with two-layer, two-layer stainless steel substrate is by heating the upper and lower surface rolled respectively in described aluminium sheet, and closely bind with described aluminium sheet, the surface roller coating of described stainless steel substrate is attached with composite coating, and described composite coating comprises the nickel dam, potassium phosphate layer and the ion plating zirconium nitride layer that set gradually from the inside to the outside.The surface roll of stainless steel substrate scribbles composite coating, greatly can improve corrosion resistance and the wearability of corrosion resistant plate, roller coat there is the upper and lower surface of stainless steel substrate calendering at aluminium sheet of composite coating, make composite coating corrosion resistant plate while having the characteristics such as the basic corrosion resistance of stainless steel, wearability, there is again the advantage that quality is light, processability is good of aluminium, and the more simple stainless steel material of being able to bear strong corrosion of cost is low.
Description
Technical field
The invention relates to stainless steel, particularly relates to the cated composite coating corrosion resistant plate of tool.
Background technology
Household electrical appliance and commercial appliance; as refrigerator, washing machine, dryer, baking box etc.; stainless steel usually can be used in its surface; because stainless steel material has good corrosion resistance, wearability and diamagnetism; its surface forms various outward appearance texture by process; have stronger ornamental; be widely used; but its cost is higher; particularly along with International Nonferrous Metals Ni; the rise of the price of Cu, some stainless prices with corrosion-resistant go up day by day, limit stainless application to a certain extent.
Summary of the invention
The object of the invention is to avoid above-mentioned weak point of the prior art and provides a kind of corrosion resistance strong, and the composite coating corrosion resistant plate of relative low price.
The object of the invention is achieved through the following technical solutions:
Provide composite coating corrosion resistant plate, comprise two-layer stainless steel substrate and one deck aluminium sheet, two-layer stainless steel substrate by heating the upper and lower surface rolled respectively in described aluminium sheet, and closely binds with described aluminium sheet.
The surface roller coating of described stainless steel substrate is attached with composite coating, and described composite coating comprises the nickel dam, potassium phosphate layer and the ion plating zirconium nitride layer that set gradually from the inside to the outside.Wherein, the thickness of described ion plating zirconium nitride layer is 0.2mm ~ 0.4mm, and the thickness of described composite coating is 0.5mm ~ 0.8mm.
In outermost surface plating one deck ion plating zirconium nitride layer of described composite coating, to improve the hardness of corrosion resistant plate, make it more wear-resisting.
The integral thickness of described composite coating corrosion resistant plate is less than 2.5mm.
The beneficial effect of the invention:
The composite coating corrosion resistant plate of the invention, the surface roller coating of its stainless steel substrate is attached with composite coating, composite coating is made up of nickel dam, potassium phosphate layer and ion plating zirconium nitride layer, greatly improve corrosion resistance and the wearability of corrosion resistant plate, various adverse circumstances can be applied to, apply more extensive.Roller coat has the upper and lower surface of stainless steel substrate calendering at aluminium sheet of composite coating, make composite coating corrosion resistant plate while having the characteristics such as the basic corrosion resistance of stainless steel, wearability, there is again the advantage that quality is light, processability is good of aluminium, by the composite coating corrosion resistant plate closely binded with general stainless steel substrate and aluminium sheet, the more simple stainless steel material of being able to bear strong corrosion of cost is low.
Accompanying drawing explanation
Accompanying drawing is utilized to be described further innovation and creation, but the embodiment in accompanying drawing does not form any restriction to the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the following drawings.
Fig. 1 is the structural representation of the composite coating corrosion resistant plate of the invention.
Reference numeral:
1-aluminium sheet,
2-stainless steel substrate,
3-composite coating, 31-nickel dam, 32-potassium phosphate layer, 33-ion plating zirconium nitride layer.
Detailed description of the invention
With the following Examples the invention is further described.
The composite coating corrosion resistant plate of the invention, as shown in Figure 1, comprises one deck aluminium sheet 1 and the two-layer stainless steel substrate 2 laying respectively at aluminium sheet 1 upper and lower surface.
Two-layer stainless steel substrate 2 is by adding the upper and lower surface of hot calender bonding at aluminium sheet 1, before calendering, first the bond area between two-layer stainless steel substrate 2 and aluminium sheet 1 is cleaned out, after superposition is placed, roll after being heated by heater, make closely to bind between two-layer stainless steel substrate 2 and aluminium sheet 1, integrate.
Be attached with composite coating 3 at the surface roller coating of stainless steel substrate 2, composite coating 3 comprises nickel dam 31, potassium phosphate layer 32 and ion plating zirconium nitride layer 33.Particularly, nickel dam 31 is plated in the outer surface of stainless steel substrate 2, and 32, potassium phosphate layer covers the surface of nickel dam 31, then in this ion plating zirconium nitride layer 33 of coating surface of potassium phosphate layer 32, thus form described composite coating.Preferably, the thickness of ion plating zirconium nitride layer 33 is 0.2mm ~ 0.4mm.The thickness of composite coating is then preferably 0.5mm ~ 0.8mm.The integral thickness of described composite coating corrosion resistant plate preferably controls in 2.5mm.
Finally should be noted that; above embodiment is only in order to illustrate the technical scheme of the invention; but not the restriction to the invention protection domain; although done to explain to the invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical scheme of the invention or equivalent replacement, and not depart from essence and the scope of the invention technical scheme.
