Problems solved by technology

Chinese patent CN1468976 discloses a surface treatment method suitable for metals and non-metals. It is mainly because the existing surface treatment method pollutes the environment, and the post-treatment has poor anti-corrosion effect and surface gloss. It is a fixed frame that can be used for positioning items. The items are fixed on the fixed frame. First, a layer of film is placed on the surface of the object, and then a metal layer is formed by vacuum plating. After that, the fixed frame and the object are directly electrocoated to make the product The surface forms a strong anti-corrosion, wear-resistant and glossy acrylic layer, which can effectively improve the problems caused by ordinary surface treatment
However, this process has the following problems: 1. It has high requirements on the external environment, and the spraying temperature is required to be above 20°C; 2. The obtained silver layer is easily oxidized and will appear yellow, black and foggy; 3. The contact between the silver layer and the substrate Poor adhesion; 4. The reagents used in the reaction are unstable and easy to deteriorate

Description

technical field [0001] The invention belongs to the technical field of surface treatment, in particular to a method for depositing a nano-alloy film layer by phase inversion technology. Background technique [0002] Many items require different surface treatments to obtain metal layers to meet decorative and functional requirements. At present, the main surface treatment methods mainly include water electroplating, vacuum coating and nano-plating. Although these methods can obtain metal layers with different properties, they all have more or less problems. [0003] Disadvantages of water plating: [0004] The electroplating process will produce a large amount of wastewater. The impurities in the electroplating wastewater are relatively complex. Most of the organic solvents contain cyanide and other highly toxic substances. For example, three polyethylenes are anesthetic and can suffocate people. Phosgene and highly corrosive hydrogen chloride can lead to fainting, high fev...
