Abstract
The utility model belongs to the technical field of mobile phone adhesive film, and particularly relates to a semitransparent and non-conducting metal reflecting film used on a mobile phone. The metal reflecting film comprises a transparent basal film made of PET (polyester), PC (polycarbonate) or PMMA (polymethylmethacrylate); a clad layer formed by sputtering a bottom SiO2 cluster layer, an Sn or Zn metal cluster layer and a top SiO2 cluster layer in sequence is arranged on the surface of the transparent basal film; and insular Sn, Zn or In metal cluster of SiO2 clusters in the top SiO2 cluster layer and the bottom SiO2 cluster layer is separated at the Sn, Zn or In metal cluster layer and is in insulation fit. Through the adoption of the structure, the metal reflecting film has the characteristics of metal reflection, semitransparency and non-conducting performance, and can not cause attenuation to radio frequency signals.
Description
Technical field
The utility model relates to and is used for the technical field that mobile phone pastes decorating film, refers in particular to a kind of translucent on the mobile phone, nonconducting metallic reflective coating that is used for.
Background technology
Metallic reflective coating is widely used in the decoration field of various consumer electronicses such as mobile phone etc., nonconducting metallic reflective coating is mainly used in the decorative appearance structural part of the electronic product of band radiofrequency signal transmitting-receiving such as mobile phone etc. such as eyeglass etc., when it keeps metallic luster and texture, can not form and disturb the transmitting-receiving of radiofrequency signal, thus the design of simplification signal receiving and transmitting system.
Be coated with the organic undercoat of last layer on the plastic cement surface, adopt evaporation process to plate layer of metal Sn on undercoat, be coated with last layer protection organic coating again on Sn coating, what obtain also is a kind of nonconducting metallic luster decorating film.This technology has the following disadvantages: 1) sticking power of coating and plastic rubber substrate is bad, therefore, must be coated with the last layer organic coating and just can carry out plated film on plastic basis material; 2) because the coating reason, can not be on transparent material direct plated film, obtain the decoration coating of translucent effect; 3) coating is oxidized easily, and therefore, when structural part adopted this coating, the organic coating protection must be carried out in the surface.Therefore, the plated film of this structure can not use on the injectable plastic material in the film at transparent material such as lens materials, IML.
Summary of the invention
This novel purpose provides a kind of translucent on the mobile phone, nonconducting metallic reflective coating that is used at the deficiencies in the prior art part exactly.
For achieving the above object, this novel technical scheme is: a kind of nonconducting metallic reflective coating, include the transparent basement membrane that constitutes by PET plastics or PC plastic material or PMMA plastic material, and be coated with bottom SiO in described transparent membrane surface sputter successively
2Grain group layer, Sn or Zn or In clipped wire group layer and top SiO
2The coating that grain group layer constitutes, top SiO
2Grain group layer and bottom SiO
2SiO in the grain group layer
2Grain group intercepts at Sn or Zn or In clipped wire group layer to become between each Sn of island or Zn or the In clipped wire group to form Insulation Coordination.
The thickness of described coating for more than or equal to 300 dusts smaller or equal to 900 dusts.
After adopting said structure, this novel employing multilayer continuous coating device and technology, utilize the bonding force of island film forming principle and different atomic group and base material different, the interference of light of different thickness rete and the theory that luminous reflectance can be controlled, realize that metal plating has the specular reflection effect of metal, simultaneously, this coating has very high face resistance, reaches at thickness under the situation of 500 dusts-900 dust, face resistance is less than 10E9, and this rete can not cause decay to the electromagnetic wave signal by it substantially.And this novel coating structure can use on transparent material and form translucent basement membrane.
Description of drawings
Fig. 1 is this novel texture principle schematic.
Embodiment
As shown in Figure 1, a kind of nonconducting metallic reflective coating includes the transparent basement membrane 10 that is made of PET plastics or PC plastic material or PMMA plastic material, is coated with bottom SiO in described transparent membrane surface 10 sputter successively
2 Grain group layer 21, Sn or Zn or In clipped wire group layer 22 and top SiO
2Grain group layer constitutes 23 coating 20, top SiO
2 Grain group layer 23 and bottom SiO
2SiO in the grain group layer 21
2Grain group intercepts between each Sn of Sn or Zn or 22 one-tenth island of In clipped wire group layer or Zn or In clipped wire group and forms Insulation Coordination.
The thickness of described coating 20 for more than or equal to 300 dusts smaller or equal to 900 dusts.
The PET plastics formal name used at school here is that polyethylene terephthalate belongs to the line style saturated polyester resin; The PC plastics formal name used at school here is a polycarbonate; The PMMA formal name used at school here is: polymethylmethacrylate; The SiO2 silicon-dioxide here; The Sn here is a metallic tin, and Zn is a metallic zinc, and In is an indium metal; The unit of length dust is 1/10th nanometers.
Because Sn or Zn or In clipped wire group layer 22 have the specular reflection effect of metal, because top SiO
2 Grain group layer 23 and bottom SiO
2SiO in the grain group layer 21
2Grain group intercepts between each Sn of Sn or 22 one-tenth island of Zn clipped wire group layer or Zn or In clipped wire group and forms Insulation Coordination, make this coating 20 have very high face resistance, reach at thickness under the situation of 500 dusts-900 dust, face resistance is less than 10E9, and this rete 20 can not cause decay to the electromagnetic wave signal by it substantially.Like this, this is novel to have metal reflective, translucent, nonconducting characteristics, can not cause decay to radiofrequency signal.Can be applied to the preceding visual window lens of mobile phone, eyeglass is a translucent effect, improved the eyeglass of original plating Cr, because plating Cr layer designed very complicated transmitting antenna, and effective standby time of battery has only 48 hours to the interference of radiofrequency signal, and adopt this novel metal reflectance coating as visual window lens, not only simplified sending antenna structure, the effective standby time of battery of the same type extends to 72 hours, and itself decorative effect and structure function are not affected.
