Description
Technical Field
The invention belongs to the technical field of gold stamping processing, and particularly relates to a gold stamping processing method for a mobile phone metal frame antenna broken seam and a mobile phone metal shell.
Background
With the thinner appearance design and larger screen size of mobile phone products, the requirement for the strength of the mobile phone shell is higher and higher, and the metal shell is applied to the mobile phone more and more. Traditional cell phone case is the plastics material, can not influence built-in antenna receiving and dispatching wireless signal. The metal housing has a great advantage in appearance and texture compared to a plastic housing. However, because metal casing's electromagnetic shield effect makes the unable signal of receiving and dispatching of antenna to influence the normal communication of cell-phone, in order to solve the signal problem, adopted the metal frame broken joint to handle on the existing market, promptly: the metal frame is disconnected in cell-phone antenna installation region and is left the gap, thereby does not let the metal casing continuity form a conductive loop and influence the receiving and dispatching of signal, then adopts the plastic that does not electrically conduct to fill, fills back plastic and flushes with the metal frame surface, guarantees the integrality of cell-phone outward appearance, can guarantee good receiving and dispatching signal again. However, this method ensures the integrity of the mobile phone shell, but the metal frame is a metal surface and has a metallic luster, and the plastic cannot achieve this luster, which results in the non-uniform appearance of the mobile phone shell, and is an aesthetic regret.
Disclosure of Invention
In order to make up the defect of beautiful appearance caused by non-uniformity of the appearance of the mobile phone shell, the plastic has the same color and metal luster as the metal frame, so that the whole mobile phone can be watched integrally without color difference, and the consistency of the appearance is realized.
In order to achieve the purpose of the invention, the technical scheme adopted by the invention is as follows:
a gold stamping processing method for a mobile phone metal frame antenna broken seam is characterized in that gold stamping paper is adopted, and gold stamping processing is carried out on the surface of the mobile phone metal frame antenna broken seam through hot-pressing hot stamping; the gilding paper comprises from top to bottom: a glue layer, an electroplated layer, a color layer, a stripping layer and a film base layer; the electroplated layer is made of tin, indium or tin-indium alloy; the thickness of the electroplated layer is 10nm-30 nm.
Furthermore, the pressurizing time of the hot-pressing and hot-stamping is 0.5-2.0 seconds, and the hot-stamping temperature is 220-300 ℃.
Further, the ratio of tin to indium in the tin-indium alloy is 3: 1.
The mobile phone metal frame shell adopts the gold stamping processing method for the mobile phone metal frame antenna broken seam to carry out gold stamping processing on the mobile phone metal frame antenna broken seam.
The invention has the beneficial effects that:
the invention relates to a gilding paper which is used for gilding the broken seam of an antenna, so that the color and the metallic luster of the plastic surface are the same as those of a metal frame, but the electroplated layers of the common gilding paper are metal layers with good conductivity such as aluminum plating, copper, silver, gold and the like, so that the gilding can influence the receiving and sending of signals. The metal has conductivity because the metal molecules have good continuity, and the continuity of the molecules becomes poor when the thickness of the tin/indium molecules is below 30 nanometers, so that the conductivity is lost, and simultaneously, the tin/indium molecules have silvery white metal reflective luster, so that the gilding paper using the tin indium as the electroplated layer is adopted to gilt the antenna seam of the metal frame of the mobile phone, so that the plastic has the same color and metal luster as the metal frame, the whole mobile phone can be viewed outside the mobile phone, the color difference is avoided, and the consistency of the appearance is realized.
