The light-transmitting adhesive is required to be colorless and transparent, has the light transmittance of more than 95 percent, has good adhesive strength, can be cured at room temperature or middle temperature, and has the characteristics of small curing shrinkage and the like.
However, the above solutions have in common that a surface treatment is made on the back side of the transparent material to enable the illusion-colour effect to be seen on the front side. The proposal has higher requirement on the transparency of the material surface, and the double-layer structure of the glass and injection molding proposal increases the product thickness (the main flow thickness is 0.65-0.8 mm).
In order to solve the problems, the scheme provides the novel battery cover plate with the multicolor effect, the design idea of the multicolor process is completed from the front side of the base plate, and the multicolor effect is achieved by performing surface treatment on the front side of the base plate. The scheme directly acts the multicolor process on the substrate, namely the bottom plate of the battery cover plate, and a layer of plate structure does not need to be additionally added on the bottom plate to serve as a carrier of the multicolor process, so that the battery cover plate provided by the scheme is of a single-layer plate structure, and the product thickness (the total thickness is about 0.35-0.42mm) can be effectively reduced while the same effect is achieved.
Specifically, referring to fig. 1, fig. 1 is a schematic view of an overall structure of a novel battery cover plate with a colorful effect according to an embodiment of the present application. An aspect of the embodiment of the present application provides a novel battery cover plate with a magic color effect, including: the surface of the substrate 1 is provided with a pattern filling area 2; the colorful effect layer 3 is covered on the pattern filling area 2; transparent sclerosis layer 4, transparent sclerosis layer 4 cover in the surface of base plate 1 just covers at least illusion-colour effect layer 3.

And this scheme is different from other battery apron that realize the illusion-colour effect equally, can furthest reduce the whole thickness of battery apron, promotes user's experience and feels and the radiating effect. The production cost can be saved in the preparation process.
The novel battery cover plate with the multicolor effect comprises a cover plate which is any one of a glass fiber plate, a composite plate of resin and glass fiber cloth, a composite plate of resin and ceramic powder or a composite plate of resin and ceramic fiber cloth. In the embodiment, the substrate 1 is preferably made of glass fiber with a thickness of 0.30-0.35 mm, the glass fiber with the thickness can meet the use strength of the battery cover plate, and the raw material manufacturing is easy to realize. In order to facilitate the subsequent realization of the multicolor process on the substrate 1, the pattern filling region 2 is provided on the surface of the substrate 1 in advance.
Illustratively, the pattern fill area 2 includes a graphic area and/or a texture area.
The pattern area comprises logo or other patterns needing mirror silver effect, and is printed on the substrate 1 through an ink silk-screen printing process.
The texture region includes texture effect patterns such as hard drawn lines, matte, bright surface textures and the like, and the required textures are transferred onto the substrate 1 through a UV transfer printing process.
The novel battery cover plate with the multicolor effect comprises an multicolor effect layer 3 which covers the pattern filling area 2.
Illustratively, the multicolor effect layer 3 is a plating layer formed by electroplating in the pattern filling region 2 by a magnetron sputtering or vacuum evaporation process. It should be noted that, in order to generate the magic color effect, the thickness of the coating layer needs to be controlled at 400-500 nm. The coating layer is one or more of an aluminum oxide layer, a niobium oxide layer, a titanium oxide layer, a vanadium oxide layer, a tungsten oxide layer, a silicon oxide layer and a silicon nitride layer.
