Specific embodiment
Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
All other embodiments obtained without creative efforts shall fall within the protection scope of the present invention.
It should be appreciated that term " comprising " and " having " used herein and their any deformation, it is intended that cover
Cover it is non-exclusive include, be not necessarily limited to for example, containing the process of series of steps or unit, method, system, product or equipment
Those steps or unit clearly listed, but may include not listing clearly or for these processes, method, product
Or the intrinsic other steps of equipment or unit.
As electronic equipment develops rapidly, mobile phone is not only the tool of a call-information, and it is daily also to become people
Ornament, the appearance of mobile phone is in recent years also in the update and innovation to emerge in an endless stream, as everybody puies forward cell phone appearance attention rate
Height, the processing technology of mobile phone are also changing.Existing frosted phone housing not only allows mobile phone to have more texture, moreover it is possible to prevent mobile phone from going out
The phenomenon that existing serious wear, some consumers show special preference to frosted phone housing very much at present.
The icon of existing frosted phone housing and symbol overlap technique generally use following methods：
Lacquer print map brushing mark and character in 1., such icon and character printing it is complete after, above spray paint, because of icon and word
Symbol is under finishing coat, so icon and character gloss are identical with finishing coat；
2. first spraying housing finishing coat, then icon slot is milled out in surface of shell, then in icon slot internal pressure textures mark stainless steel
Piece, the gloss of this programme icon is exactly the gloss of stainless steel, so highlighted smooth metal effect can be presented, but this programme needs
Increase icon steel disc, and increase steel disc hot pressing technique, processing cost is caused to increase；
3. carrying out laser marking to product surface using laser engraving machine, laser carving goes out icon and character, because finishing coat carries emery dust
Meeting extinction, causes surface the icon marking occur during grain cold carving, this icon marking, which is susceptible to, to come off, and be worn so finishing coat can only be carved
Icon and character is presented, this technique Icon Color can only be grey, and there is the left coarse effect of laser carving on surface.
The present invention is based on problem above to propose a kind of surface of shell forming method, housing and mobile terminal.
The part term in the application is explained below, so as to those skilled in the art understand that.
Priming paint is the first layer of paint system, is resisted for improving the adhesive force of finishing coat, the richness for increasing finishing coat, providing
Alkalinity provides anti-corrosion function etc., while can ensure the uniform pickup of finishing coat, paint system is made to play optimum efficiency, priming paint is then
It lays particular emphasis on and improves adhesive force, anti-corrosion function, alkali resistance etc..
Finishing coat is the final coating of application, and the overall effect showed after spraying is embodied by this layer,
Finishing coat has material therefor higher requirement, not only to there is good coloration and brightness, more requires good anti-pollution, resistance to
Aging, moisture-proof, mildew resistance is good, also to have it is free from environmental pollution, safe and non-toxic, without fire hazard, easy for construction, dried coating film it is fast,
The features such as light protects good color, good permeability is protected, there is decoration and defencive function, such as color, gloss, texture, also needed in face of disliking
The repellence of bad environment.
Laser carving is also laser engraving or laser marking, is a kind of technique being surface-treated with optical principle, laser carving
Or a kind of process of surface treatment, lettering or icon on product.
Laser engraving machine is that the permanent marking is carved out inside material surface or transparency material using radium-shine light beam.It is radium-shine
Light beam can generate substance metaplasia effect and special two kinds of effect of reason, be generated physically or chemically after substance transient absorption laser light
Reaction, so as to which indentation mark shows icon or word, also known as laser marking machine, laser engraving machine.
Sandstone paint, commonly referred to as stone similar paint, are a kind of coating of artificial stone, the coating direct spraying, decorative effect tool
There are the texture and color of lithotome, the surface of shell decorated using sandstone paint, the not only luxurious appearance with stone material and hard
Degree, and with elegance, noble, the artistic effects such as three-dimensional sense is strong.
Embodiment one：
Fig. 1 is the flow chart of surface of shell forming method that the embodiment of the present invention one provides, refering to Figure 1, this hair
The surface of shell forming method of bright embodiment includes the following steps：
S101, multiple enamelled coatings are sequentially formed on the surface of the housing；
