Problems solved by technology

[0004] Existing glass backplanes generally use colorful decorative colors, such as gradient colors, but lack the thickness of metallic colors, so a metallic glass backplane is needed, and the existing metallic glass backplanes are generally The metal film is pasted on the back of the glass with an adhesive, but the manufacturing cost of this glass plate is very high, and its physical and chemical resistance cannot meet the quality requirements. After a period of use, the glue between the metal film and the glass plate The adhesive is easy to yellow, which affects the appearance of the product, and the metal film also affects the reception and transmission of signals to a certain extent

Abstract

The invention belongs to the technical field of mobile phone parts, and particularly relates to a manufacturing method of a mobile phone backboard with metal color. The method comprises the followingsteps: S1, selecting 4-6mm transparent glass as a glass substrate; S2, forming a silk making layer by adopting a subtraction concave line pattern brushing mode; S3, printing brightening ink on the surface of the silk making layer, and sintering for the first time to obtain a silk making brightening layer; S4, printing a protective ink layer on the surface of the silk-making brightening layer, andthen sintering for the second time to obtain a metal color glass plate. A mode of coating metal color ink on a glass substrate is adopted, the metallic glass ink can stably generate color, the metal color glass plate can be cured by adopting a common baking curing molding process, metal color display of different styles can be formed by adding metal powder or organic toner according to different metal colors needing to be displayed, and the metal color glass plate is proper in apparent brightness and color and luster, is also suitable for the development trend of a mobile phone back plate, andimproves the transmitting and receiving strength of mobile phone signals.

Description

technical field [0001] The invention belongs to the technical field of mobile phone parts, and in particular relates to a method for manufacturing a back plate of a mobile phone with a metallic color. Background technique [0002] Metal backplane: Along with the lightweight of mobile phones and the advancement of metal processing technology, metal materials have begun to be widely used in mobile phones. Compared with plastic, the strength of aluminum-magnesium alloy is several times higher, and its heat dissipation performance is also much better. With the advancement of CNC and die-casting technology, processing technology is no longer an obstacle to the improvement of metal permeability. However, the same as plastics, magnesium-aluminum alloys have low hardness and are not resistant to scratches and corrosion. After long-term use, scratches will be left on the surface of the fuselage. Metal is a conductor and has the characteristics of electromagnetic shielding. Even if t...
