A processing method for integrally black surface of a 3D watch cover

Abstract

The invention relates to a processing method for integrally blackening the surface of a 3D watch cover, belonging to the technical field of watch cover surface treatment. In order to solve the problem of chromatic aberration on the surface of the existing 3D watch cover, a processing method is provided for the surface of the 3D watch cover to be blacked out. The screen printing area is used to print the ink on the surface of the plane area of ​​the edge mounting surface on the back of the 3D watch cover to form an ink layer; the 3D side wall with a gap on the back of the 3D watch cover is sprayed with ink to form an ink layer, ink printing and The ink used in the spraying process includes black pigment: 20% to 35%; polyester resin: 30% to 46%; glycol ether: 20% to 40%; xylene: 3% to 10%; , get a one-piece black 3D watch cover. The invention can realize the integral black effect with good color consistency of the ink layer in the plane area and the 3D side wall area.

Description

technical field [0001] The invention relates to a method for processing a 3D watch cover with an integral black surface, and belongs to the technical field of surface treatment of watch covers. Background technique [0002] At present, the rapid rise of smart wearable / mobile phones and the rapid development of technology, smart wearables and mobile phones are generally designed with 3D glass screens. Now the 2D glass screen integrated black technology has matured, but there are still obvious deficiencies in the surface ink of 3D products, such as 3D glass screen. The ink of the cover is usually sprayed or printed on the ink area on the back, while the structure of the back of the 3D cover generally includes a flat area on the edge mounting surface and an inwardly concave 3D groove. The 3D groove includes a bottom window area and a The 3D sidewall of the notch integrally forms the back structure of the 3D cover. The ink area on the back surface of the 3D cover (corresponding...

[0002] At present, smart wearables / mobile phones are rising rapidly, and technology is developing rapidly. Smart wearables and mobile phones are generally designed with 3D glass screens. Now 2D glass screen integrated black technology is mature, but there are still obvious deficiencies in the surface ink of 3D products, such as 3D The ink of the cover is usually sprayed or printed on the ink area on the back, and the structure on the back of the 3D cover generally includes a flat area on the edge mounting surface and a 3D groove concave inward. The 3D groove includes the window area at the bottom and has The 3D side wall of the gap forms the back structure of the 3D cover as a whole

The ink area on the back surface of the 3D cover (corresponding to the area outside the window area) usually needs to be coated with an ink layer. However, for this kind of 3D cover, it is impossible to simply use a single screen printing to process the ink layer. At the same time, due to the refraction of light due to the structural characteristics of the 3D screen, there is an obvious outline imprint between the ink layer in the plane area of ​​the installation surface and the surface ink layer in the 3D sidewall area, resulting in color difference, resulting in the 3D sidewall area. Both the color and the color of the flat area have contour marks when observed by the naked eye, which makes the surface ink color of the 3D cover product inconsistent with the color difference.
