Spraying process for nano-coating matte black decorative plate

Abstract

The invention discloses a nano-coating matte black decorative plate spraying process which comprises the following steps: step 1, surface treatment of a decorative plate: cleaning impurities such as oil stains and dust on the surface of the decorative plate by adopting a cleaning agent, and polishing a to-be-sprayed surface on the decorative plate to ensure the brightness of the to-be-sprayed surface of the decorative plate; and 2, primer spraying is conducted, specifically, the face, to be sprayed, of the decorative plate is coated with a layer of primer, so that the adhesive force of a subsequent nano coating is increased. The spraying equipment has the beneficial effects that the spraying range on the spraying equipment is flexibly adjusted according to the to-be-sprayed area on the decorative plate in the spraying process of the nano matte black coating, so that the nano matte black coating can be fully adhered to the surface of the decorative plate when the nano matte black coating is sprayed on the surface of the decorative plate; excessive waste of paint in the spraying process of the nano matte black coating is avoided, and meanwhile, the tedious operation of subsequent additional cleaning due to the fact that the paint is attached to spraying equipment is also avoided.

Description

Technical Field

[0001] The invention relates to the technical field of nano-coated matte black decorative plate processing, in particular to a nano-coated matte black decorative plate spraying process. Background Art

[0002] Nano spraying is the application of nano technology in engineering. It is a new spraying technology that forms a dense nano coating on the surface of an object. The coating contains high-hardness, high-corrosion-resistant nano materials, which can provide a variety of colors and glosses. It is an environmentally friendly, economical and durable surface treatment. When protecting the surface of decorative panels, it is often necessary to spray a nano matte black coating.

[0003] At present, the general process for spraying nano matt black coating on the surface of decorative panels is: surface cleaning, primer spraying, nano matt black coating spraying, drying and curing, quality inspection and adjustment. Although the spraying process of nano matt black coating on decorative panels can be achieved under the above spraying process, the spraying range on the spraying equipment is mostly certain under the above spraying process, which leads to the waste of paint due to the spraying range being larger than the spraying area on the decorative panels during the spraying process, and the excess paint after spraying is easy to adhere to the equipment, resulting in the need for additional cleaning later. Summary of the invention

[0004] The purpose of the present invention is to provide a nano-coated matte black decorative plate spraying process in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A nano-coated matte black decorative plate spraying process, which comprises the following steps:

[0007] Step 1: Surface treatment of the decorative board: Use a cleaning agent to remove impurities such as oil and dust on the surface of the decorative board, and polish the surface of the decorative board to be sprayed to ensure the brightness of the surface of the decorative board to be sprayed;

[0008] Step 2: Primer spraying: apply a layer of primer on the surface of the decorative panel to be sprayed to increase the adhesion of the subsequent nano coating;

[0009] Step 3: Configuration of the spraying machine: install a spraying mechanism with adjustable spraying range and spraying height on the decorative panel spraying table, and arrange an exhaust purification mechanism on one side of the spraying structure;

[0010] Step 4: Spraying of nano matte black coating: Place the decorative board after spraying the primer on the spraying table, and adjust the spraying width and spraying height on the spraying mechanism according to the width of the decorative board. At the same time, make the exhaust port of the exhaust purification mechanism face the surface to be sprayed on the decorative board, and then use the spraying mechanism to spray the nano matte black coating on the decorative board;

[0011] Step 5: Curing and drying. After spraying, a hot air blower is used to blow dry the sprayed surface of the decorative panel to ensure the rapid drying and forming of the nano matte black paint.

[0012] Step 6: Quality inspection and adjustment. After the nano matte black coating is sprayed, a CCD camera is used to inspect the surface of the decorative board to screen out unqualified decorative boards for secondary finishing.

[0013] Furthermore, in step 1, when the surface of the decorative panel is polished, it is mainly achieved with the help of polishing equipment, and the purpose of polishing is to remove the original coating, defects and the original uneven surface of the decorative panel surface, and ensure the adhesion of the subsequent spray coating layer and the surface of the decorative panel to be sprayed.

[0014] Furthermore, in step 2, when spraying the primer, it is necessary to ensure that the color of the bottom layer is similar to the color of the subsequently sprayed nano matte black coating. At the same time, spraying the primer can fill the uneven areas on the surface of the decorative board, making the surface of the decorative board smoother, and ensuring the uniformity of the thickness of the nano matte black coating after the final spray head.

[0015] Furthermore, the adjustment of the spraying range of the spraying mechanism in step 3 is mainly achieved by adjusting the spraying area at the bottom of the spraying mechanism, and the spraying area in the spraying mechanism needs to be flexibly adjusted according to the surface area of ​​the decorative panel to be sprayed. Flexible adjustment of the spraying area can effectively avoid excessive waste of paint during the spraying process, and at the same time avoid the disadvantage of excessive spray of paint adhering to the equipment and requiring additional cleaning.

[0016] Furthermore, the exhaust purification mechanism and the spraying mechanism in step 3 work synchronously. The exhaust purification mechanism is mainly used to absorb and purify the air around the decorative panel during the spraying process, and to filter and collect the nano matte black paint floating in the air around the decorative panel. The air around the decorative panel is adsorbed and purified, which can effectively ensure the cleanliness of the environment around the decorative panel.

[0017] Furthermore, in step 4, when spraying the primer on the surface of the decorative board, it needs to be done in two spraying steps to ensure the accuracy of the thickness of the nano matte black coating after the final spraying.

[0018] Furthermore, in step 5, when drying the sprayed decorative board, a mobile conveying and blowing method is used to achieve rapid drying of the nano matt black coating on the surface of the decorative board. Such drying can greatly improve the drying efficiency of the nano matt black coating on the surface of the decorative board.

[0019] The beneficial effects of the present invention are:

[0020] The present invention flexibly adjusts the spraying range of the spraying equipment according to the area to be sprayed on the decorative board during the spraying process of the nano matt black coating, so that the nano matt black coating can fully adhere to the surface of the decorative board when spraying on the surface of the decorative board, thereby avoiding excessive waste of paint during the spraying process of the nano matt black coating, and also avoiding the tedious operation of subsequent additional cleaning due to the paint adhering to the spraying equipment.
