Problems solved by technology

[0005] is not limited to the above-mentioned patents and / or patent application proposals. The vibration and noise reduction steel plate recommended is not a vibration and noise reduction steel plate in the true sense, because its The effect of vibration reduction and noise reduction is reflected by increasing the number of steel plates and setting the material with sound-absorbing and buffering function between the two layers of steel plates, so this steel plate is not suitable for the applicant's above proposal because it is heavy and expensive. And industries such as construction, vehicles, furniture, home appliances, electrical products, and steel structures
The so-called color-coated steel plate for vibration and noise reduction in the true sense should be a steel plate that reflects the technical effect of vibration and noise reduction by virtue of its own single-layer structure without adding additional steel plates. However, this steel plate There is no corresponding technical revelation in the patents and non-patent literatures that have been published so far

Embodiment 1

[0028] prepared by figure 1 The color-coated steel plate with vibration and noise reduction functions of the structure shown.

[0029] A) Uncoiling and pretreatment, uncoiling the colored galvanized steel sheet with a thickness of 1.2 mm and in the shape of a roll, and cleaning the surfaces on both sides after uncoiling. The cleaning method is preferably disk brush cleaning, and after the disk brush cleaning Alkaline cleaning and electrolytic cleaning, or pickling and electrolytic cleaning after dish brushing, or electrolytic cleaning directly after dish brushing, in order to remove surface oxide skin and / or oil stains, etc. Drying in the drying tunnel, the drying temperature is 90°C, the traveling speed of the steel plate is 60m / min, and the color coated steel plate substrate 1 is obtained;

[0030] B) Passivation treatment, preferably using a roller coating method to apply a trivalent chromium solution with a mass concentration of 30g / L at room temperature on one sid...

Embodiment 2

[0035] A) Uncoiling and pretreatment, uncoiling the color galvalume steel plate with a thickness of 0.2 mm and in the shape of a roll, cleaning the surfaces on both sides after uncoiling, and guiding the color galvanized steel plate through the drying tunnel after cleaning Drying, the drying temperature is 70°C, the traveling speed of the steel plate is 70m / min, and the color coated steel plate substrate 1 is obtained;

[0036] B) Passivation treatment, preferably using a roller coating method to apply a trivalent chromium solution with a mass concentration of 15g / L at room temperature on one side surface and the other side of the color-coated steel plate substrate 1 obtained in step A). surface, so that the first conversion layer 2 is formed on the one side surface, and the second conversion layer 3 is formed on the other side surface. In this embodiment, the first and second conversion layers 2, 3 are blunt The thickness of the chemical film layer is 1 μm, and the steel ...

Embodiment 3

[0041] A) Uncoiling and pretreatment, uncoiling the colored galvanized steel sheet with a thickness of 0.7 mm and in the shape of a roll, cleaning the surfaces on both sides after uncoiling, and guiding the colored galvanized steel sheet through the drying tunnel to dry after cleaning. The drying temperature is 80° C., the traveling speed of the steel plate is 65 m / min, and the color coated steel plate substrate 1 is obtained;

[0042] B) Passivation treatment, preferably using a roller coating method to apply a trivalent chromium solution with a mass concentration of 22g / L at room temperature on one side surface and the other side of the color-coated steel plate substrate 1 obtained in step A). surface, so that the first conversion layer 2 is formed on the one side surface, and the second conversion layer 3 is formed on the other side surface. In this embodiment, the first and second conversion layers 2, 3 are blunt The thickness of the chemical film layer is 2 μm, and th...

Abstract

The invention provides a color coated steel plate with vibration and noise reduction functions and a method for manufacturing the color coated steel plate, and belongs to the technical field of color coated steel plates. The method includes steps of uncoiling a color coated steel coil and cleaning and drying the color coated steel coil after the color coated steel coil is uncoiled; passivating a base plate of the color coated steel plate and drying the passivated base plate to obtain a steel plate to be coated with protective layers; coating a first protective layer on the surface of a first conversion coating of the steel plate to be coated with the protective layers, coating a second protective layer on the surface of a second conversion coating, baking the steel plate, then feeding the steel plate into a water tank to cool down the steel plate, and drying the steel plate by hot air after the steel plate is discharged from the water tank to obtain a steel plate to be subjected to damping treatment; coating vibration and noise reduction damping paint on the surface of the first protective layer of the steel plate to be subjected to damping treatment, and forming a vibration and noise reduction damping layer on the surface of the first protective layer to obtain an aftertreatment steel plate; and feeding the aftertreatment steel plate into a baking oven to bake the aftertreatment steel plate, feeding the aftertreatment steel plate into the water tank to cool down the aftertreatment steel plate after the aftertreatment steel plate is discharged from the baking oven, drying the aftertreatment steel plate by hot air after the aftertreatment steel plate is discharged from the water tank, and rolling the aftertreatment steel plate to obtain a finished product. The color coated steel plate and the method have the advantages that vibration amplitude and vibration are reduced, noise is suppressed, technological steps are simple, and continuous and efficient production can be realized.

Description

technical field [0001] The invention belongs to the technical field of color-coated steel plates, in particular to a color-coated steel plate with the function of reducing vibration and noise, and also relates to a preparation method thereof. Background technique [0002] Color-coated steel plate is referred to as color-coated plate or color-coated steel plate. It is a composite material formed by coating one or more layers of organic paint on the surface of a metal substrate when it passes through a color-coating unit, and then bakes and solidifies it. It is widely used in Industries such as construction, vehicles, furniture, home appliances and steel structure manufacturing.
