[0002] An air conditioner usually includes an indoor unit and an outdoor unit. Common panels of indoor units mainly include acrylic panels, PC panels and glass panels. In order to enhance the fashion sense and grade of such home appliance panels, a metal texture is often given to their surfaces. The main processing methods include electroplating and screen printing. For example, an invention patent application discloses a process for manufacturing an air conditioner curved panel with a metal texture (publication number CN106989499A), which mainly includes blank cutting and hardening treatment, electroplating, printing, laminating, bending and engraving steps. The air conditioner curved panel produced by this manufacturing process has a strong metal texture, does not crack or discolor, and is durable. However, the steps are complicated, the cost of electroplating and printing is high, and the metal texture layer is easily scratched and worn.

[0007] In step 1, the decorative sheet is a PET sheet.

[0008] In step 1, the liquid metal powder is liquid aluminum or liquid silver, and the roll coating thickness of the liquid metal powder is 8-15 um.

[0009] In step 2, the protective film is a PETG film, and the protective film is coated on the outer surface of the decorative sheet by UV glue.

[0010] In step 4, the substrate is a PC substrate, a PMMA substrate or a glass substrate.

[0011] In step 4, the curing speed is 6 to 8 s / m.

[0012] In step 5, the post-processing is a bending process and / or an ultrasonic fastener welding process.

[0013] An air conditioning panel comprises a substrate and a decorative sheet bonded to the substrate, wherein the side of the decorative sheet close to the substrate is an inner surface, and the side of the decorative sheet away from the substrate is an outer surface, and a liquid metal texture layer and a protective film layer are compounded in sequence from the inside to the outside on the outer surface of the decorative sheet.

[0014] The substrate is a PC substrate, a PMMA substrate or a glass substrate, and the decorative sheet is a PET sheet.

[0015] The liquid metal texture layer is a liquid silver texture layer or a liquid aluminum texture layer, and the protective film layer is a PETG film.

[0016] After adopting the above technical scheme, the present invention provides a manufacturing process for an air-conditioning panel with a metallic texture, wherein the liquid metal powder is rolled onto the outer surface of the decorative sheet, and then heated and rolled out in a rolling device to produce a liquid metal texture, and then bonded to a substrate to obtain an air-conditioning panel, so that the surface of the air-conditioning panel forms a flowing metallic texture, and can present a unique metallic texture and color effect, and the surface texture can achieve a visual and tactile concave and convex three-dimensional sense, which is unique. Moreover, the texture layer formed by the liquid metal is sun-resistant, wear-resistant, scratch-resistant, has a long service life, and has a wide range of market application value. This manufacturing process can not only manufacture flat air-conditioning panels, but also manufacture curved air-conditioning panels. BRIEF DESCRIPTION OF THE DRAWINGS
